title: Do orthodontists recommend Class II treatment according to evidence-based knowledge?

description: AbstractIntroductionThe adequate indications for the timing of treatment for Class II malocclusion are mandatory for the ethical and efficient practice of orthodontics, but clinicians are reluctant to accept new information that contradicts their preferred method of treatment.ObjectiveThe aim of this investigation was to assess the agreement regarding the indications for Class II malocclusion interceptive therapy between a group of international opinion-makers on early treatment and a group of orthodontists and to compare their treatment indications with the current evidence-based knowledge.Material and methodAn electronic survey containing photographs of mild, moderate and severe Class II malocclusions in children was sent to two panels of experts. Panel 1 (n=28) was composed of international orthodontists who had authored world-class publications on early orthodontic treatment, and Panel 2 (n=261) was composed of clinical orthodontists. Based on a 5-point Likert-type scale, the orthodontists selected their therapy option for each of the 9 Class II malocclusion cases.ResultThe Class II malocclusion treatment recommendations of Panel 2 were significantly different from those offered by Panel 1 with a skew of at least 1 scale point toward earlier treatment. The Class II malocclusion treatment recommendations of the members of Panel 1 members were in accordance with contemporary evidence-based knowledge.ConclusionClass II malocclusion overtreatment appears to be the tendency among clinical orthodontists but not among orthodontists who are academically involved with early treatment. There is a gap between the scientific knowledge and the practices of orthodontists.

title: Reduction of the dentin proteolytic activity after short periods of application of proanthocyanidin

description: AbstractIntroductionCollagen cross-linkers have been investigated as inhibitors of the enzymatic activity of dentin, therefore improving the longevity of adhesive restorations.PurposeTo evaluate the effect of etched dentin treatment with proanthocyanidin (PA) in short periods of time on the inhibition of dentin metalloproteinases (MMP) activity in situ.Material and methodForty dentin specimens (1x1x6mm) were obtained from sound third molars and divided into 4 groups (n=10). The specimens were etched with 37% phosphoric acid for 15s and rinsed in deionized water. Then they were treated with the following solutions: water, 5% PA for 5s, 15s or 30s. The total MMP activity was analyzed by a colorimetric test (SensoLyte®). Absorbance data (412nm) were submitted to ANOVA and Tukey tests (α=0.05).ResultAll treatment periods were able to reduce the total activity of MMPs. The best results were observed for dentine treated with PA for 15s (63.1% reduction) and 30s (70.2%). Treatment for 5s was capable of inhibiting only 39.9% of the total MMP activity.ConclusionApplication of PA on the etched dentin in extremely short periods of time reduced the MMPs activity of dentin, even after 5s. However, the best results were obtained for the longer periods.

title: The knowledge level of dental surgeons regarding the relationship between occlusal factors and Temporomandibular Disorders (TMD)

description: AbstractIntroductionThe relationship between dental occlusion and temporomandibular disorders (TMD) remains a subject of disagreement. Many professionals erroneously base diagnosis and treatment strictly on the occlusal factor, despite the fact that current scientific evidence does not show such a relationship.ObjectiveTo evaluate the knowledge of dental surgeons (DSs) from João Pessoa (PB)-Brazil, regarding the relationship between occlusal factors and TMD.Materials and methodA sample of 100 DSs who do not have expertise in TMD and orofacial pain (CG Group) and seven DSs with this specialty (EG Group) completed a questionnaire that addresses issues concerning knowledge of TMD and its relationship with occlusal factors. The questionnaire also contained information used to characterize the sample, such as age, gender, and length of experience. The current literature's degree of consensus was established as the "gold standard" response for each statement and was compared with the responses of the specialists and non-specialists. Data were tabulated using the SPSS software package and analyzed descriptively (by percentage) and statistically using the chi-square and Fisher's exact tests (p &lt; 0.05).ResultA wide divergence could be observed between the knowledge of DSs who do not specialize in TMD and orofacial pain and that of professionals who do.ConclusionThere was low agreement between specialists and non-specialists. The relationship between dental occlusion and TMD remains unclear for the vast majority of participating professionals, which may prove to be reflected in diagnostic behaviors and inappropriate occlusal treatment for the management of TMD.

title: Oral health, the perspective of the inmate and the context of vulnerability

description: AbstractIntroductionThe increase in prison populations is a phenomenon which is systematically rising throughout the world, leading to overcrowding of prisons, which has direct consequences on the health conditions of the individuals.ObjectiveTo explore the relationship among oral health, the life path and the perception of subjects in a vulnerability context.Material and methodThis is a qualitative study, developed with inmates in a State Penitentiary. To obtain and process the data, individual interviews and the Thematic Content Analysis technique were used.ResultThe interviewees showed limited perception of the process of oral health and disease fostered by the experiences of relatives and by knowledge acquired in the street or from the media. The life path in prison seemed to have little influence on this understanding. However, the prison experience influenced the oral condition of the inmates by facilitating access to dental service, oral hygiene materials and the improvement in their health knowledge and habits. The oral health results presented were, generally, in agreement with so-called common sense and with studies developed in socially similar populations.ConclusionThus, considering the limitations imposed by the way data were collected, in prison and in a vulnerability context; a non-harmful influence on the condition studied regarding the oral health of inmates is suggested.

title: Influence of one- or two-stage methods for polymerizing complete dentures on adaptation and teeth movements

description: Abstract Introduction The quality of complete dentures might be influenced by the method of confection. Objective To evaluate the influence of two different methods of processing muco-supported complete dentures on their adaptation and teeth movements. Material and method Denture confection was assigned in two groups (n=10) for upper and lower arches according to polymerization method: 1) conventional one-stage - a wax trial base was made, teeth were arranged and polymerized; 2) two-stage method - the base was waxed and first polymerized. With the denture base polymerized, the teeth were arranged and then, performed the final polymerization. Teeth movements were evaluated in the distances between incisive (I-I), pre-molars (P-P), molars (M-M), left incisor to left molar (LI-LM) and right incisor to right molar (RI-RM). For the adaptation analysis, dentures were cut in three different positions: (A) distal face of canines, (B) mesial face of the first molars, and (C) distal face of second molars. Result Denture bases have shown a significant better adaptation when polymerized in the one-stage procedure for both the upper (p=0.000) and the lower (p=0.000) arches, with region A presenting significant better adaptation than region C. In the upper arch, significant reduction in the distance between I-I was observed in the one-stage technique, while the two-stage technique promoted significant reduction in the RI-RM distance. In the lower arch, one-stage technique promoted significant reduction in the distance for RI-RM and two-stage promoted significant reduction in the LI-LM distance. Conclusion Conventional one-stage method presented the better results for denture adaptation. Both fabrication methods presented some alteration in teeth movements.

title: Performance of fluorescence-based methods in evaluating dentin caries removal

description: Abstract Introduction Clinical criteria have been used for the determination of the presence of residual caries, however in a subjective manner. Then the use of auxiliary methods that assist in determination of the remaining presence of caries can be considered for this purpose. Objective Evaluate the in “in vitro” efficacy fluorescence induction methods in the diagnosis of removing artificial dentinal caries. Material and method Ninety-four thirds sound human molars without occlusal enamel were used for microbiological artificial caries lesion induction. The decayed tissue was removed and the remaining dentin evaluated by two examiners with DIAGNOdent, DIAGNOdent pen and Quantitative Light-Induced Fluorescence - QLF. After all assessments, sections of the specimens were observed and photographed in stereoscopic lens with 30× increase by an independent examiner. These images were analyzed with Image J software, allowing quantitation of remaining caries tissue in mm2. The inter-examiner reliability, sensitivity, specificity, and area under the ROC curve was calculated and the McNemar test (p&lt;0.05) was used to compare the different among methods. Result Of the 94 teeth, 51 (54.2%) had residual caries. The sensitivity, specificity, and area under the ROC curve were similar for the three methods (p&gt;0.05). The inter-examiner agreement ranged between 0.952 and 0.978. Conclusion Among the methods used, the DIAGNOdent, DIAGNOdent pen showed better performance in residual caries detection after dentin caries removal when compared to QLF.
