RESUMO

The objective of this study was to evaluate the effect of the simplified ethanol wet-bonding technique on luting of posts to intraradicular dentin. The effect was assessed by push-out bond strength testing and confocal laser scanning microscopic analysis. Thirty endodontically treated roots were distributed into 3 groups (n = 10): water wet-bonding; stepwise ethanol wet-bonding; and simplified ethanol wet-bonding. After cementation of the posts, the roots were sectioned. Specimens were stored for 24 hours or 1 year before they were stressed to failure. Specimens from each group were processed for microscopic analysis. Data were analyzed using a 2-way analysis of variance and the Tukey test (α = 0.05). Statistically significant differences in push-out bond strength values were observed between the technique groups (P < 0.001) and between the storage periods (P = 0.009). The bond strength results in the group bonded using the simplified ethanol wet-dehydration approach did not differ from those in the group bonded using the stepwise ethanol technique at either storage time interval (P > 0.05). From 24 hours to 1 year, there was a similar decrease in bond strength for specimens prepared with the simplified and stepwise techniques. The microscopic results confirmed that ethanol wet-bonding technique improved the quality of the interface. The simplified ethanol wet-dehydration protocol achieved bond strengths and stability over time that were similar to those obtained with the stepwise ethanol technique and may be considered an alternative strategy to accomplish resin cement-root dentin bonding.

RESUMO

Abstract Introduction Mandibular fractures represent a high percentage of all facial fractures, and the bite force is a fundamental parameter to measure the actual mandibular function and, subsequently, the masticatory efficiency and quality of life. Objectives The purpose of the present systematic review was to verify if there is any difference in the bite forces of patients with mandibular fractures fixed by locking or non-locking plates, testing the null hypothesis of no difference in this parameter. Data Synthesis A systematic review of the literature was conducted using four databases (PubMed, Virtual Health Library,Web of Science and Science Direct) without restrictions as to publication date or language. We found 3,039 abstracts, and selected 4 articles for this review. Conclusion The overall results show better performance in bite force for the locking plates when compared with the non-locking plates in the incisor region (mean deviation [MD]: 1.18; 95% confidence interval [95%CI]: 0.13-2.23), right molar region (MD: 4.71; 95%CI: 0.63-8.79) and left molar region (MD: 10.34; 95%CI: 4.55-16.13). Although the results of this study indicated a better bite force result with the locking plates, there is still no sufficient evidence to support this information safely.

RESUMO

OBJECTIVE: This study aimed to examine whether Sjögren syndrome (SS) is related to periodontal status. STUDY DESIGN: A systematic review was performed on the basis of PRISMA (PROSPERO: CRD42017055202). A search was performed in the PubMed/MEDLINE, LILACS, Web of Science, and Science Direct databases. Hand searches and review of the gray literature were also performed. Three researchers independently selected studies, extracted data, and assessed methodologic quality. Studies that correlated primary and/or secondary SS with plaque index, gingival index, probing depth, and bleeding on probing were included. The risk of bias was estimated on the basis of the Newcastle-Ottawa scale. RESULTS: Seventeen studies were included in the review and 9 included in the meta-analysis, with a total of 518 and 544 patients, with or without SS, respectively. The mean difference of plaque index (0.29; 95% confidence interval [CI] 0.17-0.41), gingival index (0.52; 95% CI 0.14-0.89), and bleeding on probing (9.92; 95% CI 4.37-15.47) were larger in patients with SS than in controls. In primary SS (0.47; 95% CI 0.10-0.83) and secondary SS (0.74; 95% CI 0.10-1.38), only the mean gingival index was larger compared with that in control group. The majority of the included studies were judged as having a high risk of bias. CONCLUSIONS: The present review did not provide strong evidence that periodontal status is affected by SS.

RESUMO

Objetivo: o objetivo deste estudo foi verificar a correlação entre a avaliação da ansiedade realizada por meio de medidas fisiológicas e pela observação do comportamento de pacientes com paralisia cerebral realizado pelo dentista durante a primeira consulta odontológica. Métodos: quarenta pacientes com idade variando de 7 a 26 anos, com paralisia cerebral foram submetidos a exames odontológicos. A pressão arterial e a frequência cardíaca foram aferidas no início e no final da primeira consulta odontológica. O dentista avaliou o comportamento antes e após o exame clínico dentário através da observação do comportamento do paciente (inquietação / agitação / tiques nervosos, palidez, transpiração excessiva, resistência e mudança aparente na frequência respiratória). Foi utilizado o teste de correlação de Spearman para determinar a correlação entre as medidas fisiológicas e a classificação comportamental da ansiedade feita pelo cirurgião dentista a um nível de significância de 95%. Resultados: os sinais comportamentais mais frequentes foram inquietação / agitação / tiques nervosos (50,0%) e resistência (27,5%). Foi encontrada uma correlação positiva significativa entre os dois métodos de avaliação de ansiedade utilizados (p <0,05). Os pacientes considerados ansiosos pelo dentista apresentaram medidas fisiológicas mais elevadas do que aqueles considerados calmos (p <0,05). Conclusão: a observação contínua do comportamento de pacientes com paralisia cerebral durante o exame odontológico é uma ferramenta valiosa para o reconhecimento e avaliação da ansiedade por parte da equipe odontológica. Estudos adicionais são necessários para validar um código de expressões faciais e corporais ou reações de ansiedade em pacientes com paralisia cerebral.(AU)


Aim: The present study aimed to verify the correlation between the evaluation of anxiety performed through physiological measures and the observation of the behavior of patients with cerebral palsy performed by the dentist during the first dental visit. Methods: Forty patients with cerebral palsy, varying from seven to 26 years of age, were submitted to dental examinations. The blood pressure and heart rate were measured at the beginning and end of the first dental appointment. The dentist evaluated the behavior before and after the dental exam by observing the patient's behavior (restlessness / agitation / nervous tics, pallor, excessive perspiration, resistance, and apparent change in breathing rate). The Spearman correlation test was used to determine the correlation between the physiological measures and the behavioral classification of anxiety made by the dentist at a significance level of 95%. Results: The most frequent behavioral signs were restlessness / agitation / nervous tics (50.0%), and resistance (27.5%). Through the Kruskal-Wallis test and Spearman's correlation, a significant positive correlation was found between the two anxiety assessment methods used in this study (p<0.05). The patients considered anxious by the dentist presented higher physiological measurements than did those considered calm (p<0.05). Conclusion: It can therefore be concluded that the continuous observation of the behavior of patients with cerebral palsy during the dental examination is a valuable tool for the recognition and evaluation of anxiety on the part of the dental team. Further studies are warranted to validate a code of facial and body expressions or anxiety reactions in patients with cerebral palsy.(AU)
