Med Oral Patol Oral Cir Bucal. 2017 Dec 23. pii: 21965. doi: 10.4317/medoral.21965. [Epub ahead of print]

Abstract

BACKGROUND:

To compare the analgesic effect of anesthetic infiltration of lidocaine 2% and low-level laser therapy (LLLT) by GaAlAs into tender points of patients with orofacial pain and fibromyalgia (FM).

MATERIAL AND METHODS:

A randomized clinical trial was performed with adults (N=66) that were allocated into two groups (1:1): Group A received LLLT irradiation by Diode Laser GaAlAs (780nm) with expositions twice a week during six weeks and Group B was treated with anesthetic infiltration of lidocaine 2% without vasoconstrictor once a week for four weeks. The pain assessment included the Visual Analogic Scale (VAS) and tenderness to palpation.

RESULTS:

No dropout and adverse effect was observed during the study. The pain decreased significantly in each group after the treatment (p=0.0001, β=1.0), even though no statistical difference was found between both treatments (p=0.46, β= 0.82). The presence of tender points decreased after both treatments, with responsively in some types of masticatory muscles (p<0 .05="" a="" and="" both="" did="" effective="" except="" few="" improve="" muscle.="" not="" p="" patients="" perception="" posterior="" reported="" showed="" temporalis="" that="" the="" treatment="" treatments="" welfare.="" were="">

CONCLUSIONS:

The LLLT by GaAlAs and anesthetic infiltration of lidocaine 2% were equally effective to control orofacial pain in FM individuals.

Comparison of Effect of Oral Premedication with Ibuprofen or Dexamethasone on Anesthetic Efficacy of Inferior Alveolar Nerve Block in Patients with Irreversible Pulpitis: A Prospective, Randomized, Controlled, Double-blind Study.

Bull Tokyo Dent Coll. 2017;58(4):231-236. doi: 10.2209/tdcpublication.2016-0050.

Abstract

The purpose of this prospective, randomized, double-blind, placebo-controlled study was to determine the effect of preoperative oral administration of ibuprofen or dexamethasone on the success rate of inferior alveolar nerve block (IANB) in patients with symptomatic irreversible pulpitis. Seventy-eight patients with irreversible pulpitis were randomly divided into 3 groups (26 per group) and given one of the following at 1 hr prior to performing local anesthesia: a placebo; 400 mg ibuprofen; or 4 mg dexamethasone. Each patient recorded their pain level on a visual analog scale before taking the medication or placebo, at 15 min after completion of IANB, and during treatment if pain occurred. The success of the anesthesia was defined as no or mild pain at any stage during the endodontic procedure. The success rate of the IANB was 38.5, 73.1, and 80.8% with the placebo, ibuprofen, and dexamethasone, respectively. Both ibuprofen and dexamethasone were significantly more effective than the placebo. No significant difference was observed, however, between the two experimental medications in terms of effectiveness. The results of the present study suggest that premedication with ibuprofen or dexamethasone increases the success rate of an IANB in patients with symptomatic irreversible pulpitis in the mandibular molars.

The prevalence of occupational health-related problems in dentistry: A review of the literature.


J Occup Health. 2017 Dec 6. doi: 10.1539/joh.17-0188-RA. [Epub ahead of print]

Abstract

The study was conducted to report on the scope and prevalence of occupational health related-problems experienced by dentists, dental therapists, and oral hygienists in their practice of dentistry.

BACKGROUND:

Professional practice and dental training have many risk factors, and the dental team should be able to recognize these factors to protect themselves. The prevalence of conditions related to the musculoskeletal system, stress, percutaneous injuries, ears, and eyes are of concern. The dental team should also not forget hepatitis B, hepatitis C, and HIV as risks in practice. Dental practitioners should protect themselves by self-recognizing risk factors and by maintaining proper working conditions.

METHODS:

The study targeted all empirical research, case studies, and systematic literature reviews written in English. All articles selected were subjected to a data analysis process. Data were captured on an Excel spreadsheet and reported in a comprehensive table.

RESULTS:

The literature addressing occupational health among dental practitioners included mainly cross-sectional studies and review papers (2001-2016). Forty-nine studies were included in the review. Musculoskeletal disorders remain the most researched occupational health-related problems in dentistry. Eye protection compliance was low among practitioners. Percutaneous injuries especially among young dentists and students were still a concern.

CONCLUSION:

Occupational health-related problems are still prevalent in current dentistry practice, despite changes in equipment and surgery design. The reported prevalence of occupational related-health problems and other findings of investigative studies highlight the need for continuous professional education and a need to improve clinical practice aspects of dentistry curricula.

Metal free, full arch, fixed prosthesis for edentulous mandible rehabilitation on four implants

Technical procedure

Abstract

Purpose

The goal of this work is to describe an implant-prosthetic protocol for rehabilitation of edentulous mandible, by using a fixed prosthesis made of fiber-reinforced composite material (FRC). The protocol contemplates a minimal invasive surgery and ensures predictable and safe results, with good aesthetic and performance combined to cost savings.

Methods

FRC material is used to build the substructure of a prosthetic framework supported by four short implants (5 mm long and 4 mm wide). The prosthesis substructure is made of Trinia immersed in a matrix of epoxy resin (FRC). It is supplied in milling blocks (pre-cured) for the CAD/CAM (computer-aided design/computer-aided manufacturing) technique.
Implants are placed in lower edentulous jaw in position of first molar and canine, each side. Four month after, a resin bar is build based on a stone model, denture teeth are placed and the occlusion is checked. The resin bar and the stone model with milled abutments are scanned and a FRC bar is achieved with the CAD/CAM technique. The teeth are mounted to the substructure trough denture resin. Temporary cementation of framework is achieved on the abutments connected to the implants.

Conclusion

A protocol for a fixed mandibular implant-prosthetic rehabilitation is described. The protocol contemplates a minimal invasive surgery and ensures predictable and safe results, with good aesthetic and performance combined to cost savings. In addition, this technique allows performing basic surgery also in presence of atrophy.

Factors affecting the outcomes of direct pulp capping using Biodentine




Abstract

Introduction

This study aimed to evaluate the prognostic value of factors with regard to the treatment outcome of direct pulp capping using Biodentine (Septodont, Saint-Maur-des-Fossés, France), in permanent teeth in which the pulps were exposed during caries removal.

Methods

Between 2010 and 2014, 112 teeth with deep carious lesions underwent direct pulp capping. The patients were followed up at 2–3 months and 1–1.5 years with a routine examination on both recall visits. Periapical radiographs were taken at 1–1.5 years. Lack of patient complaints, positive reactions to cold and electric testing, no sensitivity to percussion, and no widening of the periapical ligament indicated success. The Fisher exact test was used for statistical analysis. The significance level was P = .05.

Results

Eighty-six teeth were available for 1–1.5 years follow-up. The overall success rate was 82.6%. Only age had a significant effect on the pulpal survival rate: the success rate was 90.9% in patients younger than 40 years and 73.8% in patients 40 years or older (P = .0480). Sex, initial or secondary caries treatment, occlusal or cervical/proximal caries, delayed placement of permanent filling, tooth position, and arch type did not influence the outcome.

Conclusions

A patient’s age influenced the outcome of direct pulp capping using this new calcium silicate cement.

Clinical relevance

Asymptomatic vital permanent teeth with cariously exposed pulp can be treated successfully by direct pulp capping using Biodentine.

Effect of Er:YAG laser enamel conditioning and moisture on the microleakage of a hydrophilic sealant

Odontology
pp 1–7 | Cite as

Abstract

For a given sealant, successful pit and fissure sealing is principally governed by the enamel conditioning technique and the presence of moisture contamination. A new generation of hydrophilic resin sealants is reported to tolerate moisture. This study investigates the impact of Er:YAG laser pre-conditioning and moisture contamination on the microleakage of a recent hydrophilic sealant. Occlusal surfaces of extracted human molars were either acid etched (n = 30), or successively lased and acid etched (n = 30). Ten teeth from each group were either air-dried, water-contaminated, or saliva-contaminated prior to sealing with UltraSeal XT® hydro™. Samples were inspected for penetration of fuchsin dye following 3000 thermocycles between 5 and 50 °C, and the enamel–sealant interfaces were observed by scanning electron microscopy (SEM). Significant differences in microleakage were evaluated using the Mann–Whitney U test with Bonferroni adjustment (p = 0.05). Laser pre-conditioning significantly reduced dye penetration irrespective of whether the enamel surface was moist or dry. Microleakage of water-contaminated acid etched teeth was significantly greater than that of their air-dried or saliva-contaminated counterparts. SEM analysis demonstrated good adaptation in all groups with the exception of water-contaminated acid etched teeth which exhibited relatively wide gaps. In conclusion, this hydrophilic sealant tolerates the presence of saliva, although water was found to impair its sealing ability. Laser pre-conditioning significantly decreases microleakage in all cases.

The Effect of Membrane Coverage on the Resorption of Autogenous Intraoral Block Grafts IN HORIZONTAL RIDGE AUGMENTATION: A Systematic Review of Literature and Meta-Analysis: Inevitability or an Iatrogenic Vulnerability?

Journal of Evidence Based Dental Practice

Abstract

Background

Autogenous intraoral block grafting is the gold standard augmentation technique for moderate-to-severe horizontal ridge deficiency. However, the graft undergoes variable resorption during healing that might jeopardize the outcome of the procedure. Several studies hypothesized that covering the graft with a membrane decreases the amount of graft resorption, but this effect is not established in the literature.

Objective

The objective of this study is to assess the clinical value of covering intraoral block grafts with membranes in horizontal ridge augmentation regarding graft resorption (primary outcome), graft success, net bone gain, and complications (secondary outcomes).

Data sources

Till August 2017, the review team conducted an electronic search including PubMed, EMBASE, Cochrane, and LILACS databases; we also identified other articles through hand searching. The search terms included alveolar ridge augmentation, bone transplantation, block graft, guided bone regeneration, membranes, resorbable membrane, and nonresorbable membrane.

Study selection

The review included human randomized controlled trials, controlled clinical trials, cohort studies, and case–control studies in English that compared membrane coverage to no membrane coverage of autogenous intraoral block grafts and reported the amount of graft resorption after > 3-month follow-up.

Study appraisal

Two authors independently assessed the risk of bias using the Cochrane risk of bias tool, and the third reviewer was the judge in case of conflict.

Data extraction

Two authors independently filled the effective practice and organization of care form for data extraction, and the third reviewer revised the data.

Data synthesis

The statistical method of choice was the generic inverse variance, and the results were pooled using random-effect models, with the effect size measure being mean difference (MD) for continuous outcomes and risk ratio (RR) for dichotomous outcomes.

Results

The review members screened 2266 records; we excluded 2231 records by the title and abstract and screened 35 full-text records for eligibility, from which we excluded 32 articles for certain reasons (the most common were a different comparison and excluded study design). Three randomized controlled trials were included in the quantitative and qualitative analyses of this review, providing the data for 41 participants with 49 sites. Data analysis showed a statistically significant potential benefit of membrane coverage in decreasing the amount of graft resorption of intraoral block grafts (MD: −1.20 mm, 95% confidence interval [CI]: −2.11 to −0.30, P = .009). There was no statistically significant benefit from the use of membranes regarding graft success (RR: 1.02, 95% CI: 0.89–1.17, P = .79) and net bone gain (MD: 0.46, 95% CI: −0.16 to 1.09, P = .15). The use of membranes did not show a statistically significant increase in the incidence of complications (RR: 1.80, 95% CI: 0.55–5.96, P = .33). The reviewers judged all the studies as of fair quality regarding the risk of bias.

Conclusion

The use of membranes decreased the graft resorption, but there was no difference regarding graft success and net bone gain. The use of membranes did not increase complications. Furthermore, properly conducted studies should be used to justify the adjunctive use of barrier membranes with block grafts.

Evaluation of Related Factors in the Failure of Endodontically Treated Teeth: A Cross-sectional Study

January 2018Volume 44, Issue 1, Pages 38–45 

Abstract

Introduction

The aim of this study was to review the factors related to the failure and extraction of unsuccessful endodontically treated teeth.

Methods

A total of 1000 teeth treated with nonsurgical root canal therapy were analyzed, and the following information was recorded for each patient: reasons for failure and extraction, type of tooth, presence and type of coronal restoration, smoking status, age, gender, and level of education. One main reason was recorded for each failed tooth. The associations between reasons for failure, patient, and tooth were tested by using χ2 analysis.

Results

Of the 1000 endodontically failed teeth analyzed in this study, 28.1% (n = 281) were extracted, 66% (n = 660) were re-treated, and 5.9% (n = 59) were treated with apical surgery. Among the reasons for failure, restorative and endodontic reasons were seen most frequently (43.9%, n = 439), whereas orthodontic reasons were seldom seen (0.1%, n = 1). The most common reason for extraction was for prosthetic reasons (40.8%), and perforation/stripping was the least common (2.9%). The mandibular first molars were the most frequently extracted teeth (27.4%, n = 77).

Conclusions

The most common reason for the extraction of endodontically treated teeth was for prosthetic reasons. Among the reasons for failure, restorative and endodontic reasons were the most frequently seen, and orthodontic reasons were the most seldom. The teeth that failed most frequently were mandibular first molars, and the teeth that failed least frequently were maxillary third molars. The most common reason for the extraction of failed endodontically treated teeth was for prosthetic reasons.

Inter-and intra-examiner reliability of bitewing radiography and near-infrared light transillumination for proximal caries detection and assessment.

Dentomaxillofac Radiol. 2017 Dec 11:20170292. doi: 10.1259/dmfr.20170292. [Epub ahead of print]

Abstract

OBJECTIVES:

The purpose of this in vitro study was to evaluate the inter- and intra-examiner reliability of digital bitewing (DBW) radiography and near-infrared light transillumination (NIRT) for proximal caries detection and assessment in posterior teeth.

METHODS:

From a pool of 85 patients, 100 corresponding pairs of DBW and NIRT images (~1/3 healthy, ~1/3 with enamel caries and ~1/3 with dentin caries) were chosen. Twelve dentists with different professional statuses and clinical experience repeated the evaluation in two blinded cycles. Two experienced dentists provided a reference diagnosis after analysing all images independently. Statistical analysis included the calculation of simple (κ) and weighted Kappa (wκ) values as a measure of reliability. Logistic regression with a backward elimination model was used to investigate the influence of the diagnostic method, evaluation cycle, type of tooth, and clinical experience on reliability.

RESULTS:

Altogether, inter- and intra-examiner reliability exhibited good to excellent κ and wκ values for DBW radiography (Inter: κ = 0.60/ 0.63; wκ = 0.74/0.76; Intra: κ = 0.64; wκ = 0.77) and NIRT (Inter: κ = 0.74/0.64; wκ = 0.86/0.82; Intra: κ = 0.68; wκ = 0.84). The backward elimination model revealed NIRT to be significantly more reliable than DBW radiography.

CONCLUSIONS:

This study revealed a good to excellent inter-and intra-examiner reliability for proximal caries detection using DBW and NIRT images. The logistic regression analysis revealed significantly better reliability for NIRT. Additionally, the first evaluation cycle was more reliable according to the reference diagnoses.

Quality of Life of Implant-Supported Overdenture and Conventional Complete Denture in Restoring the Edentulous Mandible: A Systematic Review



doi: 10.1097/ID.0000000000000668
Meta-Analyses and Systematic Reviews

Objective: The aim of this systematic review was to evaluate the oral health-related quality of life (OHRQoL) associated with an implant-supported overdenture (IOD) compared with a conventional complete denture (CCD) in restoring the edentulous mandible.
Methods: A literature search was performed in the MEDLINE (through Ovid), PubMed, and Cochrane Library databases for articles published between 1990 and July 2016. The search was restricted to articles published in English. Two reviewers selected the articles based on the inclusion and exclusion criteria. Another 2 reviewers analyzed the data.
Results: From 108 articles that were obtained, 5 articles met the inclusion criteria. Four studies had a high risk of bias, and 1 study had an unclear risk of bias. There was a significant difference in Oral Health Impact Profile (OHIP) scores between pre- and post-treatment within the groups and in posttreatment OHIP scores between IOD and CCD groups.
Conclusion: Regarding the edentulous mandible, patients benefited more from the IOD with 2 implants, as determined by OHRQoL scores. Considering the differences between each domain of the Oral Health Impact Profile (OHIP) questionnaire and the lack of long-term performance, more random control trials with sufficient sample sizes need to be designed to investigate long-term performance after treatment.

The Effect of Disinfection with Chlorhexidine on the Shear Bond Strength of Equia Resin-Modified Glass Ionomer Cement to Dentin in Permanent Teeth after Two Thermocycling Protocols


Abstract


Statement of the Problem: There are some concerns regarding the effect of chlorhexidine (CHX) applied for cavity disinfection on the bond strength of adhesive restorations to dentin.
Purpose: This study sought to assess the effect of CHX on the shear bond strength (SBS) of Equia resin-modified glass ionomer cement (RMGIC) to dentin in permanent teeth.
Materials and Method: In this experimental study, the buccal surface of 84 freshly extracted human premolars was ground to expose the flat dentin. The samples were randomly assigned to four groups (n=21). The steps were as following in the group Ia: conditioning, Equia RMGIC, 500 thermal cycles; group Ib: conditioning, Equia RMGIC, 6000 thermal cycles; group IIa: conditioning, CHX, Equia RMGIC, 500 thermal cycles, and group IIb: conditioning, CHX, Equia RMGIC, and 6000 thermal cycles. Twenty samples from each group were subjected to SBS test and one sample was inspected under a scanning electron microscope. Data were analyzed using two-way ANOVA and t-test.
Results: The SBS was significantly different among the groups (p= 0.007). The groups subjected to 500 thermal cycles showed significantly higher SBS to dentin when they were treated with CHX (p= 0.000). There was no significant difference between samples thermocycled for 6000 cycles with and without application of CHX (p= 0.269). The SBS in the groups that were thermocycled for 6000 cycles (Ib and IIb) was lower than those thermocycled for 500 cycles (Ia and IIa). This difference between IIa and IIb was statistically significant (p= 0.007).
Conclusion: Chlorhexidine can positively affect the short term SBS of Equia RMGIC to dentin.

The Risk Factors in Early Failure of Dental Implants: a Retrospective Study

Abstract


Statement of the Problem: Despite the low failure rate of dental implants, recognition of the risk factors can enhance the predictability of failure.
Purpose: The aim of this study was to evaluate the risk factors for early implant failure.
Materials and Method: This retrospective cohort study was conducted on two groups of patients, the patients with a failed implant before loading and those without a failed implant. Age, gender, implant type, implant surface, implant length, bone type, type of surgery (one- or two-stage) and immediate (fresh socket) or delayed placement of implant were the variables to be assessed in this study.
Results: Out of the 1,093 evaluated implants, 73 cases (6.68%) failed in early stages. The two groups were significantly different in terms of implant surface, fresh socket placement, prophylactic use of antibiotics, and bone density (p< 0.05). Age, gender, implant height, implant type (cylindrical or tapered) and one-stage or two-stage placement were not significantly different between the two groups (p> 0.05).
Conclusion: It seems that prophylactic antibiotic therapy, implant surface, bone density and placement in fresh extraction socket may contribute to dental implant failure.

Effect of Simplifying Drilling Technique on Heat Generation During Osteotomy Preparation for Dental Implant


doi: 10.1097/ID.0000000000000692
Basic and Clinical Research
Objectives: To test the hypothesis that there would be no difference in heat production by reducing the number of drills during the implant site preparation relative to conventional drilling sequence.
Methods: A total of 120 implant site preparations with 3 different diameters (3.6, 4.3, and 4.6 mm) were performed on bovine ribs. Within the same diameter group, half of the preparations were performed by a simplified drilling procedure (pilot drill + final diameter drill) and other half using the conventional drilling protocol (pilot drill followed by graduated series of drills to widen the site). Heat production by different drilling techniques was evaluated by measuring the bone temperature using k-type thermocouple and a sensitive thermometer before and after each drill.
Results: Mean for maximum temperature increase during site preparation of the 3.6, 4.3, and 4.6-mm implants was 2.45, 2.60, and 2.95° when the site was prepared by the simplified procedure, whereas it was 2.85, 3.10, and 3.60° for the sites prepared by the conventional technique, respectively. No significant difference in temperature increase was found when implants of the 3 different diameters were prepared either by the conventional or simplified drilling procedure.
Conclusions: The simplified drilling technique produced similar amount of heat comparable to the conventional technique that proved the initial hypothesis.

Immediate Versus Delayed Loading of Postextraction Implants: A Long-Term Retrospective Cohort Study


doi: 10.1097/ID.0000000000000635
Basic and Clinical Research
Purpose: To compare the long-term clinical and radiographic outcomes between immediate loading (IL) and conventional loading of implants placed immediately in fresh extraction sockets.
Materials and Methods: Demographic data, implant details, and periapical radiographs of patients were collected. The long-term marginal bone level remodeling and implant survival rate were calculated.
Results: Twenty-one patients (mean age 52.55 ± 14.61 years) with 35 implants immediately inserted into postextraction sites (22 immediate loaded and 13 delayed loaded) were analyzed. The mean follow-up duration was 6 years (range 2–11 years). The implant cumulative survival rate was 96.5%. At the longest follow-up, the mean crestal bone level averaged 0.144 ± 0.705 for IL and 0.161 ± 0.877 for delayed loading, respectively. The mean implant aesthetic score was 7.
Conclusions: IL does not negatively influence the long-term prognosis of implants inserted into fresh extraction sockets.

Bone Resorption During Submerged Healing After Guided Bone Regeneration: A Prospective Case Series


doi: 10.1097/ID.0000000000000686
Basic and Clinical Research
Objective: The aim of this study was to evaluate bone resorption quantitatively during the healing period subsequent to ridge augmentation.
Materials and Methods: Sixteen patients requiring vertical ridge augmentation before implant placement were recruited in the study. The study used an allograft and nonresorbable membrane. A custom acrylic stent was used to measure changes in bone volume. Augmented bone was compared with remaining bone 6 months after guided bone regeneration (α = 0.05 by means of the paired t test).
Results: All sites following the six months post-surgery were analyzed. Overall changes in alveolar bone were observed with a mean resorption rate of 19.8% (p<0 .001="" 18.7="" 22.8="" 26.0="" 26.5="" 42.1="" a="" among="" an="" average="" bone="" complications="" exposure="" four="" horizontal="" including="" indicated="" mean="" measurement="" membrane="" of="" p="" post-operative="" range="12.6%" rate="" rates.="" resorption="" showed="" sites="" sixteen="" the="" vertical="" with="">
Conclusion: Loss in graft quantity was observed after ridge augmentation using an allograft and nonresorbable membrane during submerged healing before implant placement. Further studies with larger sample sizes are recommended to confirm its findings.

Management of the Maxillary Diastema by Various Dental Specialties

 

Abstract

Purpose

There is considerable controversy in the literature concerning the indications for frenectomy for treating a maxillary diastema, as well as timing of the procedure. The purpose of this study was to survey pediatric dentists, orthodontists and oral and maxillofacial surgeons regarding their opinion about this matter in an attempt to develop a consensus.

Materials and Methods

An anonymous 7-item electronic questionnaire was sent to members of the American Academy of Pediatric Dentists, the American Association of Orthodontists and the American Association of Oral and Maxillofacial Surgeons asking about etiology of the maxillary diastema, its diagnosis, and treatment.

Results

Although there was not agreement among the oral and maxillofacial surgeons regarding timing of frenectomy and when the diastema should be closed, the pediatric dentists and orthodontists generally agreed that frenectomy should not be done before the permanent canines are erupted and that the operation should follow orthodontic closure of the space.

Conclusion

Although there was no complete consensus among the 3 groups, a logical treatment approach for the maxillary diastema is proposed.

Accuracy of extraoral bite-wing radiography in detecting proximal caries and crestal bone loss.

J Am Dent Assoc. 2017 Oct 28. pii: S0002-8177(17)30788-2. doi: 10.1016/j.adaj.2017.08.032. [Epub ahead of print]

Abstract

BACKGROUND:

Extraoral bite-wing (EB) radiography is an imaging technology used in dentistry. The authors conducted an in vivo study comparing the accuracy of intraoral bitewing (IB) radiographs and EB radiographs for proximal caries and bone loss diagnosis.

METHODS:

The authors recruited 116 patients who received IB radiographs to receive EB radiographs. The 5 calibrated authors made a consensus radiographic diagnosis of proximal caries and crestal bone loss. For this study, they assumed IB radiographs as the criterion standard. Next, they obtained EB radiographs for the 116 patients and calculated sensitivity, specificity, and false-positive rates against each patient's IB radiograph.

RESULTS:

The patients' EB radiographs revealed a significantly greater number of caries and crestal bone loss findings compared with their IB radiographs. The EB radiographs had a high to excellent sensitivity and moderate to low specificity of caries and crestal bone loss findings, respectively. Considering IB radiographs to be the criterion standard, the false-positive rate for EB radiographs was moderate for caries and high for bone loss diagnosis.

CONCLUSIONS:

The EB radiographs, which generate fewer images of overlapping proximal surfaces, have the advantage of detecting more carious lesions and bone loss findings than the IB radiographs do, but with the disadvantage of more false-positive diagnoses. Further research is needed to evaluate if the false-positive findings represent true carious lesions and bone loss.

PRACTICAL IMPLICATIONS:

EB radiography is a promising technology, which has several advantages over traditional IB radiography. Clinicians should be aware of false-positive diagnosis of caries and bone loss with EB radiography.

Three-camera setup to record simultaneously standardized high-definition video for smile analysis


Introduction

Our objective was to develop a photographic setup that would simultaneously capture subjects' smiles from 3 views, both statically and dynamically, and develop a software to crop the produced video clip and slice the frames to study the smile at different stages.

Methods

Facial images were made of 96 subjects, aged 18 to 28 years, in natural head position using a standardized setup of 3 digital single lens reflex cameras, with a reference sticker (10 × 10 mm) on the forehead of each subject. To test the reproducibility of the setup, 1 operator took 3 images of all subjects on the same day and on 3 different days in a subset of 26 subjects.

Results

For the same-day observations, correlation coefficients varied between 0.87 and 0.93. For the observations on 3 different days, correlation coefficients were also high. The duplicate measurement error and the mean difference between measurements were small and not significant, pointing to good reliability.

Conclusions

This new technique to capture standardized high-definition video and still images simultaneously from 3 positions is a reliable and practical tool. The technique is easy to learn and implement in the orthodontic office.

Comparison of the effect of endodontic-periodontal combined lesion on the outcome of endodontic microsurgery with that of isolated endodontic lesion: survival analysis using propensity score analysis

Original Article

Abstract

Objectives

The purpose of this retrospective clinical study was to evaluate the effect of lesion types related to endodontic microsurgery on the clinical outcome.

Materials and methods

Patients who underwent endodontic microsurgery between March 2001 and March 2014 with a postoperative follow-up period of at least 1 year were included in the study. Survival analyses were conducted to compare the clinical outcomes between isolated endodontic lesion group (endo group) and endodontic-periodontal combined lesion group (endo-perio group) and to evaluate other clinical variables. To reduce the effect of selection bias in this study, the estimated propensity scores were used to match the cases of the endo group with those of the endo-perio group.

Results

Among the 414 eligible cases, the 83 cases in the endo-perio group were matched to 166 out of the 331 cases in the endo group based on propensity score matching (PSM). The cumulated success rates of the endo and endo-perio groups were 87.3 and 72.3%, respectively. The median success period of the endo-perio group was 12 years (95% CI: 5.507, 18.498). Lesion type was found to be significant according to both Log-rank test (P = 0.002) and Cox proportional hazard regression analysis (P = 0.001). Among the other clinical variables, sex (female or male), age, and tooth type (anterior, premolar, or molar) were determined to be significant in Cox regression analysis (P < 0.05).

Conclusion

Endodontic-periodontal combined lesions had a negative effect on the clinical outcome based on an analysis that utilized PSM, a useful statistical matching method for observational studies.

Clinical relevance

Lesion type is a significant predictor of the outcome of endodontic microsurgery.
