Outcomes of implant therapy in patients with a history of aggressive periodontitis. A systematic review and meta-analysis

Theodoridis, C., Grigoriadis, A., Menexes, G. et al. Clin Oral Invest (2016). doi:10.1007/s00784-016-2026-6



To investigate the outcomes of implant therapy in partially dentate patients treated for aggressive periodontitis (GAgP) in comparison to periodontally healthy (HP) and patients treated for chronic periodontitis (CP) utilizing radiographic and clinical parameters.

Material and methods

An electronic search of databases, supplemented by hand searching, was conducted to identify relevant clinical studies. Sequential screenings at the title, abstract and full-text levels were performed independently and in duplicate. A random effects meta-analysis was conducted and bias corrected bootstrap 95 % confidence intervals were estimated for group comparisons.


The search strategy revealed a total of 899 results. After title screening, abstract scanning, and full-text reading, seven articles fulfilled the inclusion criteria. The 3-year survival rate for CP and HP patients was 100 % while in GAgP subjects, the respective value was 97.98 %; this difference being statistically significant. The 3-year mean marginal bone loss (MBL) was 1.07 mm for the GAgP group, 0.47 mm for the CP group, and 0.69 mm for the HP group. A significant difference between the GAgP and CP groups was identified (p < 0.05). The weighted mean differences of MBL concerning the above groups were also calculated and examined for statistical significance in both 1 and 3 years.


The 3-year survival rate and peri-implant marginal bone loss was found statistically significantly lower in GAgP subjects (SR 97.98 % vs 100 %) in comparison to HP and CP individuals.

Clinical relevance

The outcome of implant therapy in terms of survival rate and marginal bone loss is considered very important for the clinician in decision making when placing implants in patients with a history of aggressive periodontitis.

Panoramic radiographs made before complete removable dental prostheses fabrication: A retrospective study of clinical significance

Available online 23 December 2016


Statement of problem

The value of digital panoramic radiographs to screen for problems before fabricating conventional complete removable dental prostheses is unclear.


The purpose of this retrospective study was to examine the influence of pretreatment digital panoramic radiographs on the clinical management of patients receiving complete removable dental prostheses.

Material and methods

The clinical records, including panoramic radiographs, of 169 patients seeking new complete removable dental prostheses over a 6-year period were interpreted independently by both a prosthodontist and an oral and maxillofacial radiologist to identify radiographic findings that influenced clinical patient management. A 95% confidence interval and an observed proportion of agreement were used to interpret the results.


Sixty percent of the 169 radiographs examined had 1 or more abnormal or positive radiographic findings; however, only 6 (<4 165="" 3="" abnormalities="" and="" clinical="" detected="" during="" examination.="" identified="" influenced="" management="" of="" p="" patient="" the="" them="" were="">


Pretreatment digital panoramic radiographs revealed very few abnormalities that influenced the treatment of patients requiring complete removable dental prostheses. Furthermore, the digital images in this study revealed positive findings at a rate similar to those found in studies assessing analog radiographs, reinforcing current guidelines that recommend against radiographic screening of patients who seek new complete removable dental prostheses.

Training to become a scuba diver? Start at the dentist

Scuba divers may want to stop by their dentist's office before taking their next plunge. A new pilot study found that 41 percent of divers experienced dental symptoms in the water, according to new research from the University at Buffalo.
Due to the constant jaw clenching and fluctuations in the atmospheric pressure underwater, divers may experience symptoms that range from tooth, jaw and gum pain to loosened crowns and broken dental fillings.
Recreational divers should consider consulting with their dentist before diving if they recently received dental care, says Vinisha Ranna, BDS, lead author and a student in the UB School of Dental Medicine.
"Divers are required to meet a standard of medical fitness before certification, but there are no dental health prerequisites," says Ranna, who is also a certified stress and rescue scuba diver.
"Considering the air supply regulator is held in the mouth, any disorder in the oral cavity can potentially increase the diver's risk of injury. A dentist can look and see if diving is affecting a patient's oral health."
The study, "Prevalence of dental problems in recreational SCUBA divers," was published last month in the British Dental Journal.
The research was inspired by Ranna's first experience with scuba diving in 2013. Although she enjoyed being in the water, she couldn't help but notice a squeezing sensation in her teeth, a condition known as barodontalgia.
Published research on dental symptoms experienced while scuba diving is scarce or focuses largely on military divers, says Ranna, so she crafted her own study. She created an online survey that was distributed to 100 certified recreational divers. Those who were under 18-years-old, ill or taking decongestant medication were excluded.
Her goal was to identify the dental symptoms that divers experience and detect trends in how or when they occur.
Of the 41 participants who reported dental symptoms, 42 percent experienced barodontalgia, 24 percent described pain from holding the air regulator in their mouths too tightly and 22 percent reported jaw pain.
Another five percent noted that their crowns were loosened during their dive, and one person reported a broken dental filling.
"The potential for damage is high during scuba diving," says Ranna, who has completed 60 dives.
"The dry air and awkward position of the jaw while clenching down on the regulator is an interesting mix. An unhealthy tooth underwater would be much more obvious than on the surface. One hundred feet underwater is the last place you want to be with a fractured tooth."
The study also found that pain was most commonly reported in the molars and that dive instructors, who require the highest level of certification, experienced dental symptoms most frequently. This frequency is likely attributed to more time spent at shallower depths where the pressure fluctuations are the greatest, says Ranna.
The Professional Association of Diving Instructors has issued more than 24 million certifications around the world. As scuba diving gains popularity as a recreational sport, Ranna hopes to see oral health incorporated into the overall health assessments for certification.
Patients should ensure that dental decay and restorations are addressed before a dive, and mouthpiece design should be evaluated by manufacturers to prevent jaw discomfort, particularly when investigating symptoms of temporomandibular joint disorder in divers, says Ranna.
Additional investigators on the study include Hans Malmstrom, DDS, professor; Sangeeta Gajendra, DDS, associate professor; Changyong Feng, PhD, associate professor; and Michael Yunker, DDS, assistant professor, all of the University of Rochester School of Medicine and Dentistry.
Ranna is conducting a follow-up study with an expanded group of more than 1,000 participants.

3M Hosts First Annual Oral Health Council

International officials meet at 3M to explore needed improvements in oral health standards
ST. PAUL, Minn. – (Dec. 20, 2016) – In too many places around the world, people are suffering immensely from poor oral health. Despite its critical role in overall health, oral care is often overlooked, resulting in a population that suffers. Children who aren’t given proper access to care often have caries and struggle in school because they are in so much pain. These children grow up to become adults and elderly patients who aren’t nearly as educated or healthy as they could be. As a step to ignite worldwide change for oral health, 3M welcomed professionals and policy makers from around the world to the first-ever Oral Health Council on Nov. 28-30, 2016 at the 3M Innovation Center.

The meeting served as a forum for industry leaders from Chile, China, Bolivia, Colombia, the United Kingdom, Peru, Russia and the United States to share the challenges their countries face in delivering care to patients. Attendees learned from industry experts about preventive science innovations, how to better care for elderly, special needs and pediatric patients, and how to implement effective policy for oral health. Attendees walked away from the meeting with solid action plans to improve oral health in their communities.

“Governments are instrumental in influencing the standard for healthcare, so people with a voice must advocate for change – even if it starts small at first” said Simon Hearne, International Vice President for 3M Oral Care. “As a global industry leader, 3M is taking the responsibility to help people who can inspire change create a network that will aid them in promoting preventive oral care within their communities.”
3M plans to continue this global initiative, and looks forward to the impact this council will have on the future of worldwide oral health.

Can nocturnal use of implant-retained overdenture improve cardiorespiratory stability of a patient with obstructive sleep apnea? A clinical report

Journal of Prosthetic Dentistry


Few studies have evaluated the interaction between conventional complete dentures (CCD) and the respiratory system and the authors are unaware of any that evaluated the interaction between implant-retained overdentures (IROs) and the respiratory system. This clinical report documented the effects of wearing an IRO on the cardiorespiratory stability of an edentulous patient with obstructive sleep apnea (OSA). A 64-year-old woman was referred to the department of otolaryngology because of daytime sleepiness and morning headaches. The patient refused polysomnographic evaluation because of claustrophobia. Overnight pulse oximetry (PO) was performed to detect cardiorespiratory stability during sleep, and the oxygen desaturation index (ODI) of the patient was found to be 20.9. A mandibular advancement device (MAD) was fabricated; however, the patient did not comply with the treatment and stopped using the MAD because of intraoral discomfort. Therefore, the patient started to wear the conventional complete dentures (CCDs) nocturnally to prevent upper airway collapses. Despite the significant drop in ODI score to 12.6, because of displacement, the mandibular denture was converted to an IRO. The PO tests performed after another 6 months revealed an ODI score of 7.8. Wearing CCDs might improve respiratory stability of patients with edentulism during sleep; however, more favorable results could be obtained with IROs.

Effectiveness of DIAGNOdent in Detecting Root Caries Without Dental Scaling Among Community-dwelling Elderly

Oral Health Prev Dent 14 (2016), No. 6  (12.12.2016)

Page 555-561, doi:10.3290/j.ohpd.a37140

Purpose: The purpose of this clinical research was to analyze the effectiveness of DIAGNOdent in detecting root caries without dental scaling. 

Materials and Methods: The status of 750 exposed, unfilled root surfaces was assessed by visual-tactile examination and DIAGNOdent before and after root scaling. The sensitivity and specificity of different cut-off DIAGNOdent values in diagnosing root caries with reference to visual-tactile criteria were evaluated on those root surfaces without visible plaque/calculus. The DIAGNOdent values from sound and carious root surfaces were compared using the nonparametric Mann-Whitney U-test. The level of statistical significance was set at 0.05. 

Results: On root surfaces without plaque/calculus, significantly different (p < 0.05) DIAGNOdent readings were obtained from sound root surfaces (12.2 ± 11.1), active carious root surfaces (37.6 ± 31.7) and inactive carious root surfaces (20.9 ± 10.5) before scaling. On root surfaces with visible plaque, DIAGNOdent readings obtained from active carious root surfaces (29.6 ± 20.8) and inactive carious root surfaces (27.0 ± 7.2) were not statistically significantly different (p > 0.05). Furthermore, on root surfaces with visible calculus, all DIAGNOdent readings obtained from sound root surfaces were > 50, which might be misinterpreted as carious. After scaling, the DIAGNOdent readings obtained from sound root surfaces (8.1 ± 11.3), active carious root surfaces (37.9 ± 31.9) and inactive carious root surfaces (24.9 ± 11.5) presented significant differences (p < 0.05). A cut-off value between 10 and 15 yielded the highest combined sensitivity and specificity in detecting root caries on root surfaces without visible plaque/calculus before scaling, but the combined sensitivity and specificity are both around 70%. 

Conclusion: These findings suggest that on exposed, unfilled root surfaces without visible plaque/calculus, DIAGNOdent can be used as an adjunct to the visual-tactile criteria in detecting root-surface status without pre-treatment by dental scaling.

Effect of Whitening Toothpastes on Dentin Abrasion: An In Vitro Study

Oral Health Prev Dent 14 (2016), No. 6  (12.12.2016)

Page 547-553, doi:10.3290/j.ohpd.a36465, PubMed:27351730

Purpose: To compare the effect of toothbrushing abrasion with hydrated silica-based whitening and regular toothpastes on root dentin using contact profilometry.

Materials and Methods: Ninety dentin specimens (4 x 4 x 2 mm) were randomly divided into five experimental groups (n = 18) according to the toothpaste: three whitening (W1, W2 and W3) and two regular toothpastes (R1 and R2) produced by two different manufacturers. Using a brushing machine, each specimen was brushed with a constant load of 300 g for 2500 cycles (4.5 cycles/s). The toothpastes were diluted at a ratio of 1:3 w/w (dentifrice:distilled water). The brush diamond tip of the profilometer moved at a constant speed of 0.05 mm/s with a force of 0.7 mN.

Results: The average value of brushing abrasion in μm (mean ± SD) was obtained from five consecutive measurements of each specimen: W1 = 8.86 ± 1.58, W2 = 7.59 ± 1.04, W3 = 8.27 ± 2.39, R1 = 2.89 ± 1.05 and R2= 2.94 ± 1.29. There was a significant difference between groups (ANOVA, p<0 .0001="" all="" among="" and="" between="" but="" comparisons="" differences="" for="" multiple="" nbsp="" nor="" not="" p="" post-hoc="" regular="" s="" showed="" test="" the="" toothpastes.="" toothpastes="" tukey="" whitening="">
Conclusion: The whitening toothpastes tested can cause more dentin abrasion than the regular ones.

Relationship Between Oral Health Knowledge, Attitude and Practices of Primary School Teachers and Their Oral Health-related Quality of Life: A Cross-sectional Study

Oral Health Prev Dent 14 (2016), No. 6  (12.12.2016)

Page 519-528, doi:10.3290/j.ohpd.a37137

Purpose: To measure oral health (OH) knowledge, attitude and practices (KAP) of primary school teachers and to evaluate the relationship between these measures and oral health-related quality of life (OHRQoL).

Materials and Methods: A total of 1013 school teachers from all regions of Kuwait were randomly selected in this cross-sectional study. A questionnaire on demographics, knowledge, attitude, practices and OHRQoL was used. Frequencies and means (SD) were used for data description.

Correlations between KAP and OHRQoL were evaluated using Pearson's correlation coefficient. Associations between practice-specific knowledge and its corresponding practice as well as knowledge and practices and OHRQoL were determined using the chi-squared test.

Results: About 71% of the participants were females, 57% were 30-50 years old, and 75% had a college education. The mean (95%CI) knowledge score was 60.2% (57.2-62.0), ranging from 15.4% to 93%. The well-known OH facts were the importance of brushing twice a day with fluoridated toothpaste, the cariogenic effect of sticky, sugary foods and snacks, as well as the damage that soft drinks can cause to teeth. The least known facts were replacement frequency of toothbrush, parent's supervision of children's brushing and the benefit of regular flossing. Weak but significant correlations were found between KAP components and OHRQoL (p < 0.05). All practice-specific OH knowledge was significantly associated with its practice, except brushing and flossing (p > 0.05). Self-esteem was the mostly frequently affected OHRQoL construct by improper OH practices.

Conclusion: Oral health knowledge by itself is not enough to change improper OH practices. Developing behaviourchanging interventions based on OHRQoL outcomes may be beneficial.

Acceptance of Minimally Invasive Dentistry Among US Dentists in Public Health Practices

Oral Health Prev Dent 14 (2016), No. 6  (12.12.2016)

Page 501-508, doi:10.3290/j.ohpd.a36464, PubMed:27351729

Purpose: Little is known about use or acceptance of minimally invasive dentistry (MID) in the USA, particularly in public health settings. The purpose of this study was to assess opinions concerning MID among dentists in public-health practices.

Materials and Methods: A cross-sectional study was conducted to assess the views of dentists in public-health practices concerning MID using an online survey instrument among National Network for Oral Health Access (NNOHA) and American Association of Community Dental Programs (AACDP) members. Specific questions focused on diagnostic and preventive techniques, and whether MID was considered to meet the standard of care in the US.

Results: Overall, 86% believed that MID met the standard of care for primary teeth, and 77% did so for permanent teeth. The majority of respondents also agreed that fluoride varnish prevents caries and atraumatic restorative techniques (ART) are an effective caries treatment for children and adults. According to logistic regression results, dentists who had continuing education courses in MID and agreed that ART was an effective treatment for adults were more likely to report that MID met the standard of care for permanent teeth. Subjects who believed that fluoride varnish was effective as caries prevention for children were more likely to view MID as meeting the standard of care for primary teeth.

Conclusions: There appears to be a paradigm shift toward a MID philosophy, and most responding public health dentists believed that MID meets the standard of care for primary and permanent teeth in the US.

Randomised Clinical Trial on Resin Infiltration and Fluoride Varnish vs Fluoride Varnish Treatment Only of Smooth-surface Early Caries Lesions in Deciduous Teeth

Oral Health Prev Dent 14 (2016), No. 6  (12.12.2016)

Page 485-491, doi:10.3290/j.ohpd.a37135

Purpose: To clinically evaluate the effectiveness of resin infiltration in conjunction with fluoride varnish treatment vs fluoride varnish treatment alone on facial smooth-surface caries lesions in deciduous teeth.

Materials and Methods: This randomised clinical trial was conducted in 419 children aged 18-71 months with at least two active smooth-surface caries lesions in deciduous teeth (ICDAS II score 2). Eighty-one participants met the inclusion criteria and were allocated to one of the two treatment groups: resin infiltration and fluoride varnish (RI+FV) (n = 41) and fluoride varnish only (FV) (n = 40). The prevalence of treated white spot lesions (WSL) was scored. Fluoride varnish was applied in both groups every 3 months for a year.

Results: The mean baseline age of children was 3.8 ± 1.3 years. The effectiveness of resin infiltration measured as the percentage of children who did not present any progression of the treated lesions amounted to 43.1%. After one year, 92.1% of the infiltrated lesions (RI+FV) and 70.6% of the FV lesions had not progressed (p < 0.001).

Conclusion: Resin infiltration in conjunction with fluoride varnish treatment of early facial smooth-surface caries lesions in deciduous teeth is superior to fluoride varnish treatment alone for reducing lesion progression.

EPA Issues Final Rule Requiring Dental Practices To Use Amalgam Separators.

The ADA News (12/15, Garvin) reports the EPA released a final rule requiring that all dental practices nationwide install amalgam separators, stating in the final rule executive summary, “EPA has concluded that requiring dental offices to remove mercury through relatively low-cost and readily available amalgam separators and BMPs makes sense.” The ADA commended the EPA, who listened to the association’s input and incorporated the ADA House of Delegates’ nine principles regarding a potential amalgam rule into the final product. In a statement, ADA President Dr. Gary L. Roberts said, “The ADA believes the Environmental Protection Agency’s new federal regulation represents a fair and reasonable approach to the management of dental amalgam waste.”

        The ADA released a statement reaffirming its positionthat “dental amalgam is a durable, safe and effective cavity-filling option” and providing information for patients about restorative materials at The ADA provides more information on amalgams at

To what extent residual alveolar ridge can be preserved by implant? A systematic review

International Journal of Implant Dentistry20162:22
DOI: 10.1186/s40729-016-0057-z



It has been reported that the load for (or to) implant-supported restoration may lead to bone remodeling as bone resorption and/or formation. While many authors supported the process of bone resorption, others elaborated bone apposition and increasing bone density close and remote to implant body (or fixture). This may suggest the role of the implant to reserve alveolar ridge from physiologic/pathologic resorption. The aim of this systematic review was to predict to how extend dental implants can preserve the residual alveolar ridge based on previous clinical investigations.


This systematic review based on the retrospective and prospective studies, randomized clinical trial, and case reports. The process of searching for proposed articles included PubMed, Ovid, and Web of Science databases, with specific inclusion and exclusion criterion.


A total 2139 citations were identified. After expunging the repeated articles between databases and application of exclusion and inclusion criteria, 18 articles were found to meet the topic of this systematic review. Many of the articles reported bone preservation with implant-assisted restorations, and the rest denoted noticeable bone apposition.


According to the published clinical studies, the behavior of bone remodeling around implant predicts a sort of residual alveolar bone preservation.

Effects of low-level laser therapy on burning mouth syndrome




To investigate low-level laser therapy (LLLT) applied to treat burning mouth syndrome (BMS).

Materials and methods

This prospective. comparative. partially-blinded. single-centre. clinical trial of GaAlAs Laser. with 815 nm wavelength. included 44 BMS patients divided randomly into three groups: Group I (n=16): GaAlAs laser 815 nm wave-length. 1W output power. continuous emissions. 4 seconds .4 Joules and fluence rate is 133.3 joules/cm2.
Group II (n=16): GaAlAs infrared laser. 815 nm wavelength. 1W output power. continuous emissions. 6 seconds. 6 Joules and fluence rate 200 joules/cm2 Group III (n=12) placebo group. sham laser. All groups received a weekly dose for 4 weeks. Pain intensity was recorded using a 10-cm visual analog scale; patients responded to the oral health impact profile (OHIP-14). xerostomia severity test and the hospital anxiety-depression scale (HAD). These assessments were performed at baseline, 2 weeks and 4 weeks.


LLLT decreased pain intensity and improved OHIP-14 scores significantly from baseline to 2 weeks in Groups I and II compared with the placebo group. No statistically significant differences were found from 2 weeks to 4 weeks. Overall improvements in VAS scores from baseline to the end of treatment were: Group I 15.7%; Group II 15.6%; Group III placebo 7.3%.


LLLT application reduces symptoms slightly in BMS patients.

Capping carious exposures in adults: a randomized controlled trial investigating mineral trioxide aggregate versus calcium hydroxide




The aim of this multicentre, parallel-group randomized clinical trial was to compare the effectiveness of mineral trioxide aggregate (MTA) and a conventional calcium hydroxide liner (CH) as direct pulp capping materials in adult molars with carious pulpal exposure.


Seventy adults aged 18–55 years were randomly allocated to two parallel arms: MTA (White ProRoot, Dentsply, Tulsa Dental, Tulsa, OK, USA; n = 33) and CH (Dycal®, Dentsply DeTrey GmbH, Konstanz, Germany; n = 37). The teeth were temporized for 1 week with glass–ionomer (Fuji IX, GC Corp, Tokyo, Japan) and then permanently restored with a composite resin. The subjects were followed up after 1 week and at six, 12, 24 and 36 months. The primary outcome was the survival of the capped pulps, and the secondary outcome was postoperative pain after 1 week. Survival was defined as a nonsymptomatic tooth that responded to sensibility testing and did not exhibit periapical changes on radiograph. At each check-up, the pulp was tested for sensibility and a periapical radiograph was taken (excluding the radiographs taken at the 1-week follow-up). Kaplan–Meier survival analysis and log-rank test were used to assess the significant difference in the survival curves between groups. Chi-square test was used to assess the association between the materials and preoperative and postoperative pain.


At 36 months, the Kaplan–Meier survival analysis showed a cumulative estimate rate of 85% for the MTA group and 52% for the CH group (P = 0.006). There was no significant association between the capping material and postoperative pain.


Mineral trioxide aggregate performed more effectively than a conventional CH liner as a direct pulp capping material in molars with carious pulpal exposure in adult patients. This study has been registered at, number NCT01224925.

Apical negative pressure irrigation versus syringe irrigation: a systematic review of cleaning and disinfection of the root canal system


The aim of this study was to systematically review and critically analyse the published data on the treatment outcome (primary outcome) and on the cleaning and disinfection of root canals (secondary outcomes) achieved by negative pressure irrigation as compared to syringe irrigation. An electronic search was conducted in EMBASE, LILACS, Pubmed, SciELO, Scopus, and Web of Knowledge using both free-text keywords and controlled vocabulary. Additional studies were sought through hand-searching of endodontic journals and of the relevant chapters of endodontic textbooks. No language restriction was imposed. The retrieved studies were screened by two reviewers according to predefined criteria. Included studies were critically appraised and the extracted data were arranged in tables. The electronic and hand search retrieved 489 titles. One clinical study and 14 in vitro studies were finally included in the review; none of these studies assessed treatment outcome, 4 studies assessed the antimicrobial effect, 7 studies evaluated the removal of pulp tissue remnants, and 4 studies investigated the removal of hard tissue debris or both hard tissue debris and pulp tissue remnants. Poor standardization and description of the protocols was evident. Inconclusive results were reported about the cleaning and disinfection accomplished by the two irrigation methods. Negative pressure irrigation was more effective under certain conditions when compared to suboptimal syringe irrigation, however, the variability of the protocols hindered quantitative synthesis. There is insufficient evidence to claim general superiority of any one of these methods. The level of the available evidence is low and the conclusions should be interpreted with caution.

Management of cannabis-induced periodontitis via resective surgical therapy: A clinical report.

J Am Dent Assoc. 2016 Nov 18. pii: S0002-8177(16)30856-X. doi: 10.1016/j.adaj.2016.10.009. [Epub ahead of print]



There is a lack of clinical research on the potential effect of cannabis use on the periodontium as well as its effect on treatment outcomes. The aim of this case report is to illustrate the clinical presentation of periodontal disease in a young woman who was a chronic cannabis user, as well as successful treatment involving motivating the patient to quit cannabis use and undergo nonsurgical and surgical therapy.


A 23-year-old woman sought care at the dental clinic for periodontal treatment. During a review of her medical history, the patient reported using cannabis frequently during a 3-year period, which coincided with the occurrence of gingival inflammation. She used cannabis in the form of cigarettes that were placed at the mandibular anterior region of her mouth for prolonged periods. Localized prominent papillary and marginal gingival enlargement of the anterior mandible were present. The mandibular anterior teeth showed localized severe chronic periodontitis. The clinicians informed the patient about the potentially detrimental consequences of continued cannabis use; she was encouraged to quit, which she did. The clinicians performed nonsurgical therapy (scaling and root planing) and osseous surgery. The treatment outcome was evaluated over 6 months; improved radiographic and clinical results were observed throughout the follow-up period.


Substantial availability and usage of cannabis, specifically among young adults, requires dentists to be vigilant about clinical indications of cannabis use and to provide appropriate treatments. Behavioral modification, nonsurgical therapy, and surgical therapy offer the potential for successful management of cannabis-related periodontitis.

Posterior composites: update on cavities and filling techniques

Available online 23 November 2016




The aim of this paper is to examine cavity design for posterior resin composite restorations and to discuss various resin composite filling techniques.


Literature with regard to cavity preparation for amalgam and resin composite restorations has been reviewed. An overview of available bulkfill resin composite systems is provided and a categorization of these systems according to their clinical application and their intended use is outlined.


A literature search was carried out by the authors in Medline.

Study selection

Pre-defined inclusion criteria based on keywords were included and reviewed.


Minimum cavity preparations are advised for posterior resin composite restorations, preserving the greatest amount of healthy tooth structure. For resin composite restorations only the caries lesion needs to be removed with all remaining tooth structure protected for the bonding process. The anticipated outcome of this philosophy will result in the longer survival of teeth. Newer bulkfill restorative resins allow the operator to complete the restoration in a similar time to the placement of a dental amalgam restoration.

An association between vitamin D deficiency and early dental implant failure is not properly verified, but its role in osteoimmunology is discussed. This article illustrates two case reports with vitamin D deficiency and early implant failure. Prior to implant placement, the first patient received crestal bone grafting with autologous material. Both patients received dental implants from different manufacturers in the molar region of the mandible. In the case of bone grafting in the first patient, all implants were placed in a two-stage procedure. All implants had to be removed within 15 days after implant placement. Vitamin D serum levels were measured: Both patients showed a vitamin D deficiency (serum vitamin D level <20 affirm="" after="" and="" between="" both="" clinical="" d="" deficiency="" early="" failure.="" follow="" g="" implant="" in="" l="" must="" nbsp="" osteoimmunology="" p="" patients.="" placement="" prospective="" randomized="" relationship="" successful="" supplementation="" the="" to="" trials="" vitamin="" was="">

Study Shows OraCoat® XyliMelts® Oral Adhering Discs Effectively Treat Acid Reflux

FDA-Approved Clinical Trial Shows that XyliMelts Discs are an Effective Supplement for Treating Many Acid Reflux Symptoms

Bellevue, WA (December 1, 2016) – A recent study revealed that OraCoat® XyliMelts® oral-adhering discs greatly reduce symptoms of heartburn in acid reflux sufferers. The double-blinded, randomized, placebo-controlled study conducted by Peter Van der Ven, DMD, PhD; Jeffrey Burgess, DDS, MSD; and Michael Karcher, BA, PhD candidate; was approved by the Western Institutional Review Board and the U.S. Food and Drug Administration (FDA).

Gastro-esophageal reflux disease (GERD), more commonly known as acid reflux, describes a chronic digestive condition in which an accumulation of stomach acid in the esophagus creates symptoms. Acid reflux affects about 30 percent of the population on a weekly basis and is known to contribute to or cause a number of medical and dental problems including heartburn, sore throat, laryngitis, cough, halitosis, and tooth decay. The condition is also associated with sleep disturbance and can have a negative effect on nighttime comfort and overall quality of life.

The study aimed to prove if XyliMelts, recently rated by a Clinicians Report® survey as the most effective remedy for alleviating dry mouth could produce similar results in treating patients suffering from acid reflux, which is often managed by prescribed and over-the-counter medications that prevent excessive acid production. XyliMelts are formulated from all-natural ingredients commonly used in foods. As tests prove that salivary stimulants can decrease the perception of nighttime dry mouth, tests also suggest increased saliva can diminish nighttime reflux.

Conducted over two weeks, the study analyzed 53 test subjects who provided daily responses to nine questions listing common acid reflux symptoms that might have occurred during the prior night’s sleep. The subjects were separated into two groups, with 26 administered with XyliMelts discs delivered in unmarked packaging, while 27 subjects received the placebo treatment, a water-based gel packaged in an unmarked white tube. Neither the research coordinator nor the subjects were aware which product was being used for data collection.

Test results displayed that both the disc and gel reduced the taste of reflux, heartburn sensation, morning hoarseness, perceived reflux severity, and the number of antacids taken during the night. While both groups demonstrated comparable effectiveness in combating most symptoms, XyliMelts exhibited a profoundly higher improvement rate in lessening heartburn intensity than the placebo gel.*

Overall, the study supports the use of XyliMelts discs as a supplemental remedy for counteracting symptoms during sleep in acid reflux patients.* The discs were well tolerated by all the subjects involved with no adverse reactions reported.

Kerr Launches Harmonize™

Next generation universal composite creates lifelike, long-lasting restorations.

November 30, 2016 Kerr is pleased to announce the launch of Harmonize, a next generation universal composite infused with Adaptive Response Technology (ART), a nanoparticle filler network with features that help dentists achieve a lifelike restoration with more ease and simplicity than ever before. It’s the ART in Harmonize that creates enhanced structural integrity to provide exceptional strength, handling and esthetics.
Harmonize diffuses and reflects light in a similar way as human enamel, leading to an enhanced chameleon effect for better blending. In addition, the particle size and structure is designed to offer superior gloss retention, and easy polishability compared to leading composites.
Harmonize is softer while sculpting, holds its shape without slumping and does so without the stickiness of other composites due to the high loading, spherical shape and rheological modifier of ART.
The ART filler system allows for high loading at 81%, plus a unique reinforced nano-scale filler particle network, which leads to better polymerization, more integration with resin, strength and durability.
Harmonize provides everything doctors expect from a universal composite.
“Harmonize reflects the type of product innovation we are most proud of at Kerr — a superior product that makes the patient happier and the dentist’s day easier,” said Phil Prentice, Vice President of North America for KaVo Kerr. “Our team is committed to the continuous improvement of even our best products and we think our customers will be thrilled with Harmonize.”

Comparison of implant versus tooth-supported zirconia-based single crowns in a split-mouth design: a 4-year clinical follow-up study

Clinical Oral Investigations
, Volume 20, Issue 9, pp 2467–2473




This study aims to evaluate the 4-year clinical performance of tooth versus implant-supported single-unit zirconia crowns (LAVA™) placed on posterior region.

Materials and methods

Twenty-four patients (10 men and 14 women) who had received 48 single crowns (24 implant-supported and 24 tooth-supported) from January 2007 to December 2009, were included. California Dental Association (CDA) quality assessment system, plaque and gingival index scores were used to evaluate the performance of the crowns at baseline and at all follow-up examinations.


During the follow-up period, no fracture of zirconia coping has occurred. Major complication was chipping in three patients that required a new crown fabrication. Except for the failure ones, all crowns in both groups were rated as satisfactory at the follow-up examinations based on the CDA quality assessment criteria. There were no statistically significant differences between tooth and implant-supported crowns in terms of periodontal parameters.


The present 4-year follow-up clinical study demonstrates that single-unit tooth- and implant-supported zirconia crowns have similar prosthetic and periodontal outcomes.

Clinical relevance

Single-unit implant or tooth-supported zirconia crowns may be considered acceptable treatment modalities for restoration of either missing or compromised posterior teeth

A One-Year Evaluation of a Free Fissure Sealant Program

Journal of Dental Biomaterials
Vol 3, No 4 (2016)
Maryam Bakhtiar, Naser Azadi, Ali Golkari


Statement of Problem: Pit and fissure sealant therapy has been approved as an effective measure in the prevention of occlusal dental caries. Resin based ma- terials are the most common materials used worldwide. A variety of resin based fissure sealants are produced and used. Most of them have been presented with ideal results in research environment. However, their effectiveness in the real life, especially in a mass application program such as Iran’s oral health reform plan is not clear.
Objectives: To evaluate the longevity of different fissure sealant applied in Iran’s oral health reform plan in Fars Province (south of Iran) after one year.
Materials and Methods: Seven counties were selected. One hundred 6- to
8-year-old school children who had undergone fissure sealant therapy in spring
2015 were randomly selected from each county. Their first molars were exam- ined to evaluate the status of the fissure sealants which were applied one year ago. Data on the type/brand of fissure sealant materials, type and experience of clinicians who applied them, existence of a chair-side assistant, and whether the children were caries-free at the time of fissure sealant application were collected from the existing reports.
Results: Data of 1974 teeth from 598 children were used for the final analysis. The effects of type/brand of the material was significant on the final results and remained significant (p < 0.001) after adjustments for the level of fluoride, urban/rural area, upper/lower jaw, type of clinician who applied the sealant, existence of a chair-side assistant, and child’s gender, age, and being caries-free.
Conclusions: Many factors affect the success rate of a fissure sealant therapy program. The type/brand of the material remained significantly related to the success rate of the fissure sealant even after adjustments for other influencing factors. In this study, ClinproTM  Sealant (3M/ESPE, USA) showed better longevity after one year of application.
