Efficacy of straight versus angled interdental brushes on interproximal tooth cleaning: a randomized controlled trial

Int J Dent Hygiene DOI: 10.1111/idh.12042 Jordan RA, Hong HM, Lucaciu A, Zimmer S. Efficacy of straight versus angled interdental brushes on interproximal tooth cleaning: a randomized controlled trial.




To investigate interproximal biofilm reduction with an angled interdental brush as compared to a straight interdental brush (standard control) in a clinical, single-centre, single-blind, controlled, parallel-group trial.


Recruitment and examinations of the subjects were performed at the Witten/Herdecke University School of Dental Medicine. 128 volunteers, aged 20–65 years, were recruited and stratified according to sex and age. Two groups with 64 subjects each used either straight (standard control) or angled (test group) handgripped interdental toothbrushes of the same bristle stiffness. After a 12-day home-care habituation period, participants received a professional tooth cleaning followed by a 48-h plaque regrowth period. At the intervention appointment, plaque was recorded with a fluorescent revelator and soft tissue damage was noted (T0). Interdental brushing was performed by the participant for 2 min, and clinical parameters were recorded again (T1).
The primary efficacy end point was the difference in modified Proximal Plaque Index (mPPI) after brushing compared to baseline. Secondary efficacy end points were mPPI differences in subgroups (anterior vs. posterior teeth; vestibular vs. oral tooth surfaces). Safety end point was the Danser gingival abrasion index (DI).


mPPI showed lower scores after brushing within all (sub)groups (P < 0.01). mPPI brushing efficacy (ΔT0 − T1) in subjects using straight interdental brushes was significantly higher as compared to angled interdental brushes (P < 0.0001). Straight interdental brushes were significantly more effective in posterior teeth, when used from vestibular and from oral tooth surfaces (P < 0.0001, P < 0.01 and P < 0.0001, respectively). No significant differences were found between the groups in anterior teeth and concerning soft tissue damage.


Straight interdental brushes may better remove plaque interproximally when compared to angled interdental brushes.

Effect of brushing and accelerated ageing on colour stability and surface roughness of composites

Available online 11 July 2013



The aim of this study was to evaluate the effect of brushing and artificial accelerated ageing (AAA) on colour stability and surface roughness of aesthetic restorative materials.


One hundred and twenty specimens (12 mm diameter × 2 mm thick), 40 of each material (n = 8) were obtained using nanosized composite Z350 (3M ESPE), nanohybrid composite Tetric N-Ceram (Ivoclar Vivadent) and ceramic IPS e.max Ceram (Ivoclar Vivadent), as control. Initial colour (Spectrophotometer PCB 6807) and surface roughness (Surfcorder SE 1700) readouts were taken and the samples were separated into five groups (n = 8) and treated as follows: Group 1: mechanical brushing with dentifrice RDA* 68 (Colgate), Group 2: mechanical brushing with dentifrice RDA* 180 (Colgate Total Plus Whitening), Group 3: AAA, Group 4: AAA followed by mechanical brushing with dentifrice RDA* 68 and Group 5: AAA followed by mechanical brushing with dentifrice RDA* 180. Mechanical brushing was performed for 205 min and AAA for 480 h; new colour and surface roughness readouts were taken. Data were statistically analyzed (two-way ANOVA repeated measures, Bonferroni test, p < 0.05).


Dentifrice abrasiveness was not significant for colour change and surface roughness. When submitted to AAA+brushing, the colour stability of Tetric was statistically significant (p < 0.05) with both dentifrices and with dentifrice RDA* 180 for Z350. The roughness was different (p < 0.05) for Z350 when brushed with RDA* 68 after AAA.


Dentifrice abrasiveness did not interfere in the ability to remove stains and roughness from aged samples. However, staining is material-dependent.

Clinical significance

The abrasiveness of dentifrice does not change the colour and surface roughness of the composites and does not help to remove surface stains from the aged samples.

coughing. We conducted an evaluation of this oral sensory
system in a laboratory experiment involving 8 participants.
The results show 93.8% oral activity recognition accuracy
when using a person dependent classifier and 59.8%
accuracy when using a person independent classifier.

Effect of endodontic sealers on tooth color

Volume 41, Supplement 3, August 2013, Pages e93–e96
Journal of Color and Apperance in Dentistry




One of the goals of endodontic treatment is the adequate filling of the root canal, which is often done using gutta-percha and sealer. It has been reported that sealer remnants in the coronary pulp chamber cause tooth color changes. Therefore, this study was designed to examine the effect of endodontic sealer remnants on tooth color, testing the hypothesis that sealers cause coronal color changes.


Forty single-rooted human teeth were endodontically treated leaving excess sealer material in the coronary pulp chamber. The specimens were divided into four groups (n = 10) according to the endodontic sealer used (AH, AH Plus; EF, Endofill; EN, endométhasone N; and S26, Sealer 26). Teeth were stored at 37 °C moist environment. Color coordinates (L*a*b*) were measured with a spectrophotometer before endodontic treatment (baseline-control), 24 h and 6 months after treatment. L*a*b* values were used to calculate color changes (ΔE). Data were statistically analyzed using Kruskal–Wallis and Mann–Whitney-U tests.


Color changes were observed for all groups with S26 and EN producing the greatest mean ΔE values after 6 months.


Endodontic sealer remnants affect tooth color confirming the experimental hypothesis.

Clinical significance

This study examined the effect of endodontic sealer remnants on tooth color, and observed that after 6 months, the sealers produced unacceptable color changes.

Effect of cigarette smoke on color stability and surface roughness of dental composites

Volume 41, Supplement 3, August 2013, Pages e73–e79
Journal of Color and Apperance in Dentistry



To evaluate the color stability and surface roughness of 3 dental composites subjected to cigarette smoke and brushing.


Twenty specimens were prepared for each type of restorative material used: nanohybrid (Tetric N-Ceram); hybrid (Z250-3M ESPE) and silorane-based microhybrid (Filtek P90-3M ESPE), which were divided into 2 groups (n = 10), according to the type of finishing/polishing received: Group 1 – papers with decreasing abrasive grit and Group 2 – polyester matrix (without polishing). After initial readouts of color (Easy Shade-VITA) and surface roughness (SJ-201P Mitutoyo), specimens were subjected to action of smoke from 20 cigarettes, (Marlboro Red–Philip Morris). After each cigarette, the samples were submitted to brushing in a standardised device. After this, final readouts were taken to calculate change in color (ΔE and ΔL) and roughness (ΔRa), which were statistically analysed (2-way ANOVA, Bonferroni, and Student's-t tests respectively, p < 0.05).


Tetric N-Ceram presented color change at clinically unacceptable levels (ΔE > 3.3) when the polyester strip was used for finishing, a result differing (p < 0.05) from those of the other composites, which presented no difference between them (p > 0.05). Unpolished composites presented higher Ra values than those that were polished (p < 0.05), with exception of the silorane based composite.


Absence of polishing increases cigarette capacity to stain composites and surface roughness of composites, with exception of the silorane based type.

Safety and efficacy of a high-adhesion whitening strip under extended wear regimen

I would love to see a split test between trays and strips. MJ

Volume 41, Supplement 3, August 2013, Pages e46–e52
Journal of Color and Apperance in Dentistry



This randomized, parallel group, single centre clinical trial was conducted to evaluate the safety and compare the whitening efficacy for an extended wear of an experimental 9.5% H2O2 high-adhesion whitening strip, relative to a marketed 10% H2O2 control strip.


Twenty-nine eligible adult volunteers were randomly assigned to either a treatment series with an experimental 9.5% H2O2 high-adhesion whitening strip at home for 2 h, once a day, for 8 days; or a marketed 10% H2O2 whitening strip for 30 min, on a similar daily regimen. Tooth color/whitening progression was recorded under standardized lighting conditions at baseline, day 3, day 5, and day 9, via digital imaging. Outcomes were reported using the CIELAB system. Usage safety was also assessed at each follow-up visit. Whitening efficacy for each group was investigated using a paired-difference t-test. The treatment groups were compared among each other using the analysis of covariance, with the baseline value and age as the covariates.


Both treatment groups demonstrated statistically significant mean color improvement from baseline for b* (yellowness) and L* (lightness) at each post-baseline visit. In addition, the 2-h high-adhesion strips demonstrated significantly greater improvement in b* and L* relative to the 30-min strip group at each follow-up visit.


The 2-h regimen for the 9.5% H2O2 high-adhesion whitening strip was more efficient for tooth whitening than the 30-min regimen of 10% H2O2 whitening strip. Both treatments were well tolerated and the use of the test products during the study time frame was considered safe.

Clinical relevance

Extending the daily wear time of whitening strips can improve the efficacy of the treatment and ultimately shorten the length of the treatment without any significant adverse effects.

Optical properties of current ceramics systems for laminate veneers

I find this to be an interesting read. MJ 

Volume 41, Supplement 3, August 2013, Pages e24–e30



Full-ceramic systems can be produced by different techniques (layering, heatpressing, CAD/CAM) and have various compositions with different crystalline contents that may affect the optical properties of laminate restorations.


A total of 60 specimens were prepared from e.max Press, e.max CAD, Empress Esthetic, e.max Ceram, Inline, and ZirPress systems (A1 shade; diameter 10 mm; thickness 0.5 ± 0.05 mm). The L*, a*, and b* values, chroma and translucency (TP) of each system were recorded before and after ageing. The statistical analyses were performed by ANOVA, Tukey's tests and the paired sample t-test (p < 0.05).


The L* value of the shade guide was significantly different from those of the full-ceramic systems; however, there were no significant differences between the a* values of Ceram, Esthetic, Inline and Zirpress. There were significant differences between the b* values of the shade guide compared with the full-ceramics except for e.max Press. The L* values decreased, and the a* and b* values increased after the ageing process for all groups. There were no significant differences between the ΔE values of the ceramic systems (p > 0.05). The TP values decreased, and the chroma value increased significantly after the ageing process (p > 0.05). The chroma of the shade guide was found to be the highest.


None of the full-ceramic systems was able to match the color of the shade guide. The chemical structures of the ceramic systems were more effective for determining the optical parameters than the fabrication techniques. Ageing caused full-ceramics to become more opaque, darker, reddish and yellowish.

Evaluation of Efficacy of Different Gingival Displacement Materials on Gingival Sulcus Width

Prasanna GSR, Reddy K, Kumar RKN, Shivaprakash S. Evaluation of Efficacy of Different Gingival Displacement Materials on Gingival Sulcus Width. J Contemp Dent Pract 2013;14(2):217-221.


Aim: The purpose of the present in vivo study was to measure the efficacy of different gingival displacement materials in achieving gingival tissue displacement and to compare the efficacy of Expasyl displacement paste (Pierre Rolland, France) and gingival displacement cord for gingival displacement. Materials and methods: Sixteen subjects were included in the study. Premolars were prepared to receive full veneer crown, gingival displacement was carried using gingival retraction cord and gingival displacement paste. Impression of the gingival sulcus was made. Sulcus width after displacement was measured under magnification. Results: The mean displacement value of sulcus width was 0.21 ± 0.01 mm for the gingival retraction cord and 0.26 ± 0.02 mm for the gingival displacement paste. 'F' test was used for statistical analysis. Difference among the two test agents was statistically significant (p < 0.01). Conclusion: Gingival displacement paste showed better response in achieving horizontal displacement of the gingival sulcus than gingival retraction cord. Clinical significance: Gingival displacement helps in recording the unprepared tooth surface adjacent to the finish line in the impression being made, thereby helping a better marginal adaptation and emergence profile in the extracoronal restoration.

Degree of Conversion and Hardness of Two Different Systems of the Vitrebond™ Glass Ionomer Cement Light Cured with Blue LED.

Calixto LR, Tonetto MR, Pinto SCS, Barros ED, Borges AH, Lima FVP, de Andrade MF, Bandeca MC. Degree of Conversion and Hardness of Two Different Systems of the Vitrebond™ Glass Ionomer Cement Light Cured with Blue LED. J Contemp Dent Pract 2013;14(2): 244-249. 


This study investigated the physicochemical properties of the new formulation of the glass ionomer cements through hardness test and degree of conversion by infrared spectroscopy (FTIR). Forty specimens (n = 40) were made in a metallic mold (4 mm diameter x 2 mm thickness) with two resin-modified glass ionomer cements, Vitrebond™ and Vitrebond™ Plus (3M/ ESPE). Each specimen was light cured with blue LED with power density of 500 mW/cm(2) during 30 s. Immediately after light curing, 24h, 48h and 7 days the hardness and degree of conversion was determined. The Vickers hardness was performed by the MMT-3 microhardness tester using load of 50 gm force for 30 seconds. For degree of conversion, the specimens were pulverized, pressed with KBr and analyzed with FT-IR (Nexus 470). The statistical analysis of the data by ANOVA showed that the Vitrebond™ and Vitrebond™ Plus were no difference significant between the same storage times (p > 0.05). For degree of conversion, the Vitrebond™ and Vitrebond™ Plus were statistically different in all storage times after light curing. The Vitrebond™ showed higher values than Vitrebond™ Plus (p < 0.05). The performance of Vitrebond™ had greater results for degree of conversion than Vitrebond™ Plus. The correlation between hardness and degree of conversion was no evidence in this study.

Evaluation of Effect of Different Cavity Disinfectants on Shear Bond Strength of Composite Resin to Dentin using Two-Step Self-Etch and One-Step Self-Etch Bonding Systems: A Comparative in vitro Study.

Reddy MSC, Mahesh MC, Bhandary S, Pramod J, Shetty A. Evaluation of Effect of Different Cavity Disinfectants on Shear Bond Strength of Composite Resin to Dentin using Two-Step Self-Etch and One-Step Self-Etch Bonding Systems: A Comparative in vitro Study. J Contemp Dent Pract 2013;14(2):275-280. 


Aim and objectives: To evaluate the effect of 2% chlorhexidine, 2% sodium hypochlorite, 3% hydrogen peroxide on shear bond strength of composite resin to dentin using two-step and onestep self-etch bonding systems and to study the mode of failure of specimens under stereomicroscope. Materials and methods: Eighty extracted sound human posterior teeth were used. The occlusal surfaces were ground to expose the dentin and were then randomly divided into 4 main groups. In group I, no cavity disinfectant was used and served as control. In groups II, III, IV, 2% chlorhexidine, 2% sodium hypochlorite and 3% hydrogen peroxide were used as cavity disinfectants respectively. Each group was then divided into two subgroups of 10 teeth each according to the bonding agent used, two-step self-etch (Adper SE Plus) and one-step self-etch (Adper Easy One) respectively. A transparent cylindrical plastic tube was loaded with microhybrid composite and placed over the dentin and light cured for 40 seconds. The specimens were subjected to shear stress in the universal testing machine. Results: Pretreatment with 2% chlorhexidine, 2% sodium hypochlorite and 3% hydrogen peroxide, had a negative effect on the shear bond strength of self-etching bonding systems. Conclusion: The highest bond strength was found in 2% chlorhexidine group followed by 2% sodium hypochlorite group and the lowest bond strength was found in 3% hydrogen peroxide group. Clinical significance: All three cavity disinfectants used in this study reduced the shear bond strength and hence should be used with caution.

Use of Clinical Bleaching with 35% Hydrogen Peroxide in Esthetic Improvement of Fluorotic Human Incisors in vivo.

Shanbhag R, Veena R, Nanjannawar G, Patil J, Hugar S, Vagrali H. Use of Clinical Bleaching with 35% Hydrogen Peroxide in Esthetic Improvement of Fluorotic Human Incisors in vivo. J Contemp Dent Pract 2013;14(2): 208-216.


Aim: The aim of the study was to evaluate esthetic improvement with the use of 35% hydrogen peroxide clinical bleaching as related to the different grades of enamel fluorosis in vivo and to study adverse effect of clinical bleaching with 35% hydrogen peroxide on teeth and gingiva. Materials and methods: A total of 60 children of different grades of fluorosis were included in the study. With 35% hydrogen peroxide-based dual activated bleaching system, in-office vital teeth bleaching was carried out for each subject. Clinical evaluation for improvement in esthetics, effect on teeth and gingiva were performed for each child during preoperative, immediate postoperative and later 6 months postoperative period. For evaluation and comparison, all the collected data were subjected to statistical analysis. Results: Although in all the subjects, partial shade relapse was seen over a period of time, good homogeneous and esthetic results were seen in very mild and mild cases. A total of 35% hydrogen peroxide in-office bleaching has no adverse effect on teeth and gingiva. Conclusion: Comparing all the three groups who participated in the study, 35% hydrogen peroxide in-office bleaching seems to be very effective in very mild and mild forms of fluorosis. Clinical significance: In very mild and mild forms of fluorosis, in-office vital tooth bleaching with 35% hydrogen peroxide is the most conservative and effective approach in esthetic improvement.

New E4D® NEVO™ Scanner and Design Center Enjoys Rave Reviews from Dental Professionals

'Fast,' 'Accurate' and 'Enhanced Patient Comfort', Dentists Say

MELVILLE, N.Y., July 18, 2013 /PRNewswire/ -- Dental professionals in the U.S. recently got a sneak peak of the new E4D® NEVO™ Scanner and Design Center, created by D4D Technologies, LLC, and exclusively distributed by Henry Schein, Inc. (NASDAQ:HSIC). The product, unveiled last month at Henry Schein Dental's National Sales Meeting, received rave reviews by dental professionals using the system for the first time.

Gary Kaye, DDS, FAGD, founder and principal dentist of New York City-based Kaye Dentistry, recently hosted a hands-on demonstration of NEVO for leading dental professionals.

"The technology that E4D has developed, particularly the scanner, is just incredible," said Dr. Kaye. "Scanning inside the mouth with most systems is very difficult to do. With NEVO, one of my associates used the new wand, and after just a few minutes was immediately getting outstanding and accurate results."

That new associate, Sarah Jafari-Namin, DMD, MS, Prosthodontics, offered the following assessment:

"The system was very easy to use," said Dr. Jafari-Namin. "The hand piece is much lighter than before, which made it easier for the patient and me, and the speed of the NEVO E4D system is outstanding."

Colgate Bounces Back from Brush Swap PR Disaster as Competitors Pounce

The much-hyped Colgate Electric ToothBrush Swap launched in London's Waterloo Train Station last week, promising to exchange an old electric toothbrush for the brand's new ProClinical A1500 product, worth £170 ($256).
However, by 5am, hundreds had crowded into the rail station, toothbrushes in hand, clamoring for the freebie. To the dismay of plenty, the brand's supply of 750 new brushes was depleted by 7am, causing chaos at the station and a full-blown PR nightmare for Colgate.

A New Solvent-free One-Step Self-Etch Adhesive: Bond Strength to Tooth Structures.

Shirban F, Khoroushi M, Shirban M. A New Solvent-free One-Step Self-Etch Adhesive: Bond Strength to Tooth Structures. J Contemp Dent Pract 2013;14(2):269-274. 


Introduction: In recent years some new solvent-free dental adhesives have been marketed. This study evaluated bonding effectiveness of a new one-step solvent-free self-etch adhesive in comparison with a common two-step self-etch adhesive used as gold standard. Materials and methods: Flat enamel and dentin surfaces were prepared on 60 incisors using silicon carbide papers. Clearfil SE Bond (CSEB) and Bond 1SF (B1SF) adhesives were applied on enamel/dentin surfaces in four groups (n = 15): (1) Enamel surface and CSEB, (2) dentin surface and CSEB, (3) enamel surface and B1SF, (4) dentin surface and B1SF. Composite resin buildups were carried out using Z100 composite resin. All the specimens were stored for 24 hours at 37°C and 100% relative humidity. After 500 rounds of thermocycling, shear bond strength (SBS) test was performed using a universal testing machine at 1 mm/min crosshead speed. Data were analyzed with one-way ANOVA and a post hoc Tukey test (α = 0.05). In each experimental group, two additional specimens were prepared for scanning electron microscopy evaluation. Results: Significant differences were observed between the study groups (p < 0.001). The highest enamel/dentin bond strengths were recorded in group 1 (CSEB) (p < 0.001). The SBS of the two-step self-etch adhesive to enamel and dentin was significantly higher than that of the one-step self-etch adhesive (p < 0.001). There was no significant difference between enamel and dentin SBS with B1SF (p = 0.559). Conclusion: Within the limitations of the present study, when bonded to enamel and dentin the solvent-free adhesive B1SF underperforms as compared to CSEB as the control gold standard.

Quantum Dental Technologies (QDT) announced the findings from two key presentations last week at the 60th Congress of the European Organization for Caries Research (ORCA) in Liverpool, United Kingdom.
In the first study, lesion depth of natural caries was correlated with the readings from The Canary System, DIAGNOdent (DD), and the ICDAS II (a visual ranking system). Using polarized light microscopy to examine the tooth samples, investigators found that the Canary Numbers produced a more accurate correlation with lesion depth than either the DD or ICDAS II. This strong correlation may be explained by the ability of The Canary System to measure changes in the crystal structure of the tooth.  In contrast, other caries detection devices rely on fluorescence technology.  Fluorescence can detect the presence of bacterial porphyrins but is not capable of identifying changes in tooth crystal structure.
“With an overall Pearson’s Correlation coefficient of 0.84, The Canary System can be a great tool to aid dental professionals in the diagnosis of caries and estimation of lesion depth”, said Dr. Bennett Amaechi, Professor and Director of Cariology at the University of Texas San Antonio. “This is a very exciting development in dentistry and in the management of tooth decay”.
In the second study, the energy conversion technology PTR-LUM that powers The Canary System enabled investigators to accurately detect caries around the intact margins of ceramic crown restorations. In contrast, most of the DIAGNOdent readings did not reveal the presence of tooth decay. This study showed that The Canary System may be a valuable addition to conventional methods for detecting tooth decay that develops around ceramic crowns.
“The Canary System now provides dentists with the ability to detect tooth decay beneath the edges of fillings, crowns and bridges; one of the most common conditions that lead to the clinical failure of these restorations”, said Dr. Stephen Abrams, co-founder of Quantum Dental Technologies.  “Early detection of tooth decay, before it is seen on an x-ray or detected with visual inspection, means that dentists can treat problems before the decay has destroyed significant amounts of tooth structure”. 
The Canary System is a low-powered laser-based device that uses a novel combination of heat and light to directly examine the crystal structure of teeth. The Canary System can detect, map and monitor carious lesions on any tooth surface earlier and more accurately than other existing modalities.

Pocket Guide for Correct Periodontal Coding

Dental Hygiene Thought Leader Patti DiGangi, RDH, BS Publishes Useful Pocket Guide for Correct Periodontal Coding

DentalCodeology: More than Pocket Change Debuts in Print and Digital Formats

Addison, IL – July 10, 2013 –  Patti DiGangi, RDH, BS, a prominent dental hygiene thought leader, recently published a dental insurance coding guide entitled, DentalCodeology: More than Pocket Change.

“This book is intended to be used by the entire dental team, including hygienists, dentists and office managers,” explained DiGangi. It is intended to answer any questions regarding proper periodontal care CDT coding by the dental hygiene department in a general dental practice, which should result in better patient outcomes and expedited insurance reimbursement.”

DentalCodeology is not a reference book that will collect dust on a shelf,” DiGangi adds. “It’s designed to be on the front lines of patient care, whether in its hardcopy, pocket-sized booklet, or the downloadable digital version for smartphones.”

As part of her book launch, Ms. DiGangi is significantly reducing her $16.95 retail price. “For every book purchased at the discounted price of $12.00, I will also give the digital version for free,” explains DiGangi.  “Buy two print books for $20.00, and you can share one print copy and one digital copy.  My hope is that the hygienists who are attending RDH Under One Roof will share a copy with their colleagues who weren’t able to make the event.”

DentalCodeology: More than Pocket Change is the first book of a series designed to guide dental clinicians into the coding and electronic health records world. As dentistry moves from a
treatment-centered model to a diagnostic-centered model, consistent and accurate coding will be vital to ensure interoperability with the rest of healthcare industry.”

The book covers four of the twelve sections of CDT code related to periodontal care, including:

          D0100 - 0999   I. Diagnosis

Quantitative evaluation of apically extruded debris with different single-file systems: Reciproc, F360 and OneShape versus Mtwo




To assess in a laboratory setting the amount of apically extruded debris associated with different single-file nickel-titanium instrumentation systems compared to one multiple file rotary system.


Eighty human mandibular central incisors were randomly assigned to 4 groups (n=20 teeth per group). The root canals were instrumented according to the manufacturers’ instructions using the reciprocating single-file system Reciproc, the rotary single-file-systems F360 and OneShape and the multiple files rotary Mtwo instruments. The apically extruded debris was collected and dried in pre-weighed glass vials. The amount of debris was assessed with a micro balance and statistically analyzed using ANOVA and post-hoc Student-Newman-Keuls test. The time required to prepare the canals with the different instruments was also recorded.


Reciproc produced significantly more debris compared to all other systems (P<0 .05="" and="" between="" difference="" em="" file="" multiple="" no="" noted="" rotary="" significant="" single-file="" system="" systems="" the="" two="" was="">P
>0.05). Instrumentation with the three single-file systems was significantly faster than with Mtwo (P<0 .05="" p="">


Under the condition of this study, all systems caused apical debris extrusion. Rotary instrumentation was associated with less debris extrusion compared to reciprocal instrumentation.

Plasma rich in growth factors had limited effect on early bone formation in extraction sockets

Farina R, Bressan E, Taut A, Cucchi A, Trombelli L. Plasma rich in growth factors had limited effect on early bone formation in extraction sockets. Clin. Oral Impl. Res. 00, 2013, 13



To address the criticisms raised by Anitua et al. (European Journal of Oral Implantology, 6, 2013, 9–11) to the article “Plasma Rich in Growth Factors (PRGF) in Human Post-Extraction Sockets: an Histological and Histomorphometric Study.”, recently published by Farina and colleagues (Clinical Oral Implants Research 2012; doi: 10.1111/clr.12033).


All the methodological aspects criticized in the letter by Anitua et al. were thoroughly reconsidered and discussed in a structured short communication. When indicated, pertinent, additional material was included to reinforce our considerations.


As most clinical studies in implant dentistry, including previous studies evaluating the efficacy/effectiveness of PRGF, the study by Farina et al. has some limitations. However, it is currently the only published controlled trial using quantitative parameters related to PRGF-induced early bone formation.


Despite all limitations, the results of the study by Farina et al., which were based on different quantitative parameters (micro-CT scan, immunohistochemical markers of wound healing and bone deposition), indicated a limited effect of PRGF on early bone formation in extraction sockets.

Immediate Placement of Implants into Infected Sites: A Systematic Review




Traditionally, before placing dental implants, the compromised teeth are removed and the extraction sockets are left to heal for several months. To preserve the alveolar bone level from the collapse caused by healing and to reduce treatment time in situations in which tooth extraction precedes implant placement, some clinicians began to install the implant immediately into the postextraction socket without waiting for the site to heal.


The purpose of this study was to review the literature regarding treatment outcomes of immediate implant placement into sites exhibiting pathology after clinical procedures to perform the decontamination of the implant's site. The following questions were raised: Does the presence of periodontal or endodontic infection affect immediate implant placement success? What is suggested to address the infection in the socket prior to immediate placement?

Materials and Methods

An electronic search in PubMed (U.S. National Library of Medicine, Bethesda, MD, USA) was undertaken in March 2013. The titles and abstracts from these results were read to identify studies within the selection criteria. Eligibility criteria included both animal and human studies, and excluded any review and case reports articles. The publication's intervention had to have been implant placement into a site classified as having an infection (periapical, endodontic, perioendodontic, and periodontal).


The search strategy initially yielded 706 references. Thirty-two studies were identified within the selection criteria, from which nine were case reports and review articles and were excluded. Additional hand-searching of the reference lists of selected studies yielded five additional papers.


The high survival rate obtained in several studies supports the hypothesis that implants may be successfully osseointegrated when placed immediately after extraction of teeth presenting endodontic and periodontal lesions, provided that appropriate clinical procedures are performed before the implant surgical procedure such as meticulous cleaning, socket curettage/debridement, and chlorhexidine 0.12% rinse. However, more randomized controlled clinical trials with a longer follow-up are required to confirm this procedure as a safe treatment. Moreover, the outcome measures were not related to the type of infection; the classification of infection was often vague and varied among the studies. The benefits of antibiotic solution irrigation and systemic antibiotic administration in such conditions are not yet proved and remain unclear.

A computerised third molar surgery simulator – results of supervision by different professionals

Rosen, A., Eliassi, S., Fors, U., Sallnäs, E. .-L., Forsslund, J., Sejersen, R. and Lund, B. (2013), A computerised third molar surgery simulator – results of supervision by different professionals. European Journal of Dental Education. doi: 10.1111/eje.12060


The purpose of the study was to investigate which supervisory approach afforded the most efficient learning method for undergraduate students in oral and maxillofacial surgery (OMS) using a computerised third molar surgery simulator.
Fifth year dental students participated voluntarily in a randomised experimental study using the simulator. The amount of time required and the number of trials used by each student were evaluated as a measure of skills development. Students had the opportunity to practise the procedure until no further visible improvements were achieved. The study assessed four different types of supervision to guide the students. The first group was where they were supported by a teacher/specialist in OMS, the second by a teaching assistant, the third group practised without any supervision and the fourth received help from a simulator technician/engineer. A protocol describing assessment criteria was designed for this purpose, and a questionnaire was completed by all participating students after the study.
The average number of attempts required to virtually remove a third molar tooth in the simulator was 1.44 times for the group supervised by an OMS teacher; 1.5 times for those supervised by a teaching assistant; 2.8 times for those who had no supervision; and 3.6 times when support was provided only by a simulator technician. The results showed that the most efficient experience of the students was when they were helped by an OMS teacher or a teaching assistant. In a time and cost-effective perspective, supervision by a teaching assistant for a third molar surgery simulator would be the optimal choice.

Relationship between odontogenic bacteremia and orthodontic stripping

American Journal of Orthodontics & Dentofacial Orthopedics
Volume 144, Issue 1 , Pages 73-77, July 2013


The aim of this study was to evaluate the prevalence of bacteremia associated with an orthodontic stripping procedure.


The study included 29 orthodontic patients (mean age, 18.2 ± 3.4 years). We used a standardized stripping procedure: a perforated stripping disk with a contra-angle hand piece was used at a low speed (<15 10="" a="" aerobic="" after="" anaerobic="" analyzed.="" and="" antecubital="" anterior="" bacterial="" baseline="" before="" blood="" bottles="" by="" cannula="" collected="" culture="" cultures="" fossa.="" identified="" incubated="" inoculated="" inserting="" into="" left="" mandibular="" on="" p="" procedure.="" procedure="" rpm="" sample="" samples="" second="" seconds="" statistically="" stripping="" taken="" teeth.="" the="" these="" treatment="" was="" were="">


Transient bacteremia was not detected in any pretreatment blood sample, but it was found in 1 postoperative blood sample; this sample tested positive for Streptococcus sanguis.


The bacterial species in the positive postoperative blood sample was S sanguis, which might be associated with infective endocarditis. Clinicians should explain the level of risk to the patient and consult a concerned medical specialist.

Biomimetic mineralisation of phosphorylated dentine by CPP-ACP

Available online 25 June 2013



Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) has the potential to induce the biomimetic mineralisation of dentine collagen fibrils. This study aimed to demonstrate in vitro the ability of CPP-ACP to form apatite crystals on phosphorylated dentine collagen fibrils.


Dentine slices with a 2-mm thickness were prepared from sound human third molars. The slices were etched with phosphoric acid to expose the collagen fibres. Sodium trimetaphosphate was then used to phosphorylate the exposed collagen fibres. CPP-ACP paste was topically applied to the surface of the phosphorylated slices, which were then immersed in a metastable calcium phosphate remineralising solution and incubated at 37 °C for 10 days. The CPP-ACP paste and the remineralising solution were replaced every two days. Phosphorylated dentine slices without a CPP-ACP application and non-phosphorylated dentine slices with a CPP-ACP application were prepared and used for comparison. The slices were examined using scanning electron microscope (SEM), diffuse reflectance-Fourier transform infrared spectroscopy (DR-FTIR) and X-ray diffraction (XRD).


The SEM results revealed the presence of intrafibrillar and interfibrillar crystal nucleation and growth along the phosphorylated dentine collagen fibres. The DR-FTIR and XRD confirmed that the crystals were hydroxyapatite. No apatite crystal nucleation and growth were observed in either the slices that had no non-phosphorylation or those without CPP-ACP application.


CPP-ACP can induce the biomimetic mineralisation of dentine through apatite formation along and between the phosphorylated dentine collagen fibres.

Clinical significance

The in vitro study imitated the application of CPP-ACP to exposed dentine tooth surfaces in the mouth. This could lead to the development of a new therapeutic technique for the treatment of tooth hypersensitivity.

Paired maxillary and smaller mandibular mouthguard for rugby player with malalignment

Takeda, T., Kajima, T., Nakajima, K., Narimatsu, K., Konno, M., Hasegawa, K., Sekiguchi, C., Ozawa, T., Noh, K. and Ishigami, K. (2013), Paired maxillary and smaller mandibular mouthguard for rugby player with malalignment. Dental Traumatology. doi: 10.1111/edt.12050


A rugby player who had frequently experienced soft tissue injuries while playing rugby and wearing a conventional custom-made mouthguard came to the hospital clinic. The patient had suffered traumatic soft tissue injuries such as lip lacerations and bite trauma. Severe crowding due to ectopic maxillary and mandibular canines was observed. In response to the patient's request for better protection, a set of maxillary and mandibular mouthguards was designed: one covering the entire maxillary dentition and the other the mandibular front teeth only. The mouthguards were to be worn simultaneously. In this paper, we describe how these mouthguards were fabricated and discuss the results. The patient has experienced no injury to the stomatognathic system, including the lips, for five seasons since he began wearing this set of mouthguards. This new pairing of mouthguards appears to offer sufficient protection against injury, despite severe malalignment. We believe that this new type of paired maxillary and mandibular mouthguards has the potential to reduce sports-related dental injuries.

A practice-based randomised controlled trial of the efficacy of three interventions to reduce dentinal hypersensitivity



The aim of this study was to evaluate the efficacy of three different interventions (non-desensitising toothpaste, desensitising toothpaste and professionally applied dentine bonding agent) in reducing dentinal hypersensitivity over a two week, three month and six month period in a dental practice setting.


This was a randomised controlled, single-blind; parallel-group trial conducted in general dental practice by a single general dental practitioner. Seventy five subjects were randomly allocated to three groups; non-desensitising toothpaste (NDT), desensitising toothpaste (DT) and professionally applied desensitising agent (DA). Dentinal hypersensitivity was measured using a Visual Analogue Scale (VAS) to record the response from a standardised short blast of air from a triple syringe. Dentinal hypersensitivity was recorded at baseline, two weeks, three months and six months for all groups.


Dentinal hypersensitivity reduced significantly (p < 0.0001) in both groups DT and DA, in addition the reduction in sensitivity was sustained and continued to improve over a 6 month period. The greatest reduction in dentinal hypersensitivity was recorded in group DA.


The results from this study suggest that application of dentine bonding agents, to teeth diagnosed with dentine hypersensitivity provides the greatest improvement in dentine hypersensitivity at 2 weeks and 6 months. This reduction in dentine hypersensitivity is greater than that achieved by the desensitising toothpaste tested and a non-desensitising toothpaste.

The aim of this study was to assess the effect of different resin cement shades on the opacity and color difference of ceramics and to determine the polymerization efficiency of the resin cement at different shades after curing through ceramics.


Two different ceramics (IPSe.maxPress, and IPSEmpress®CAD, Ivoclar Vivadent) were used for this study. A light-cured veneer luting resin (Variolink Veneer, Ivoclar Vivadent) in four different shades of HV + 1, HV + 3, LV-1, and LV-3 was used for the colorimetric measurements. The colour and spectral reflectance of the ceramics were measured according to the CIELab colour scale relative to the standard illuminant D65 on a reflection spectrophotometer (ColorEye7000A,USA). Colour differences (ΔE values) and the contrast ratios (CR) of the different groups of samples were calculated. In order to analyse the polymerisation efficiency of the resin cements, the micromechanical properties of the resins were measured with an automatic microhardness indenter (Fisherscope H100 C, Germany). The results were analysed using one-way ANOVA and Tukey's HSD post-hoc tests (SPSS 18.0).


The one-way ANOVA test showed that the values of ΔE and CR of the different specimen groups were significantly different (p < 0.05). Group 1 (20.7 ± 0.5) (IPS-CAD without resin cement) exhibited the highest and group 10 (14.8 ± 0.5)(e.max:HV + 3) exhibited the lowest ΔE value. Significant differences in the micromechanical properties were identified among the tested resin cements in different shades (p < 0.05).


Resin cement shade is an important factor for the opacity of a restoration. Furthermore, the resin shade affects the micromechanical properties of the underlying resin cement.
