Educational approaches for assessing knowledge about and actions of educators in response to dental avulsion.

BACKGROUND: Dental trauma affects especially schoolchildren and adolescents. Educators, the responsible for the first appointment, have a fundamental role in the prognosis of dental avulsion that occurred in this environment. AIM: To evaluate the educational approaches for assessing knowledge and actions in response to dental avulsion among educators. SETTINGS AND DESIGN: This cross-sectional and quanti-qualitative study included 197 teachers and 24 pedagogical coordinators (PCs), from the public schools of Pato Branco, Paraná, Brazil. METHODS: A questionnaire was initially administered regarding the knowledge about avulsion to all participants. Teachers just read a manual and answered the questionnaire after 30 days. PCs were divided into (n = 12): G1 - manual + fictitious scenario of avulsion and G2 - active methodology + fictitious scenario. The questionnaire was re-administered to all. STATISTICAL ANALYSIS: Quantitative data were analyzed statistically. For the qualitative stage, two questions were proposed and the Bardin's analysis was performed. RESULTS: For teachers, knowledge about avulsion increased after the intervention (P < 0.001), except as related to cleaning the tooth (P = 0.21). Activities involving G1 and G2 also led to an increase in knowledge, but no difference occurred in this increase between the approaches (P = 0.14). Qualitative analysis highlighted the need for calm and for performing actions that could favor a good prognosis in cases of avulsion. CONCLUSIONS: The level of knowledge increased after interventions, but no significant differences between the educational approaches were found.

Perfil do usuário e tempo de espera para tratamento endodôntico público em um município brasileiro / User profile and waiting time for public endodontic treatment in a Brazilian municipality / Perfil del usuario y tiempo de espera para tratamiento endodóncico público en un municipio brasileño

RESUMO Objetivo Avaliar o perfil do usuário e o tempo de espera para tratamento endodôntico no Centro de Especialidade Odontológicas (CEO) Positivo, localizado na cidade de Curitiba, PR. Brasil. Métodos Este estudo transversal utilizou dados primários de 77 pacientes que aguardavam na fila de espera para a especialidade de Endodontia, de março a de julho de 2017. Os dados coletados foram: tempo de espera, gênero, idade, dentes referenciados e quantidade de encaminhamentos por Unidade de Saúde do serviço público. Resultados O tempo médio de espera foi de aproximadamente 11 meses. Do total, 56% eram do gênero feminino, com média de idade de 35,5 anos. Os dentes mais referenciados foram os póstero-inferiores. Conclusão O tempo na fila de espera é considerado longo, o que requer maior diálogo com a atenção básica para a formulação de estratégias voltadas à redução dos agravos bucais e à maior capacitação profissional para diagnóstico e condução dos casos.

Cone-Beam Computed Tomography Detection of Separated Endodontic Instruments.

INTRODUCTION: This study compared the accuracy, sensitivity, and specificity of different imaging diagnostic protocols, cone-beam computed tomography (CBCT) and digital periapical radiography (DPR), in identifying separated endodontic instruments in filled root canals. METHODS: One hundred eight root canals from 36 mandibular molars were prepared and obturated. Of these, 84 were filled without separated instruments, and 24 were filled with the presence of a separated instrument (stainless steel hand file or reciprocating instrument). Subsequently, different CBCT imaging protocols were acquired: i-CAT Classic (ICC) (0.25-mm isotropic voxel), i-CAT Next Generation (ICN) (0.125-mm isotropic voxel), and PreXion 3D (PXD) (0.09-mm isotropic voxel). Moreover, a DPR exam was obtained (08 mA, 70 kVp, and exposure time of 0.2 seconds). Two calibrated endodontists evaluated each image for the presence or absence of fractured files on a 5-point scale, ranging from definitely absent to definitely present. The accuracy, sensitivity, and specificity measures for each method were estimated. The data were evaluated by Fisher exact test and binomial test. RESULTS: Nine instruments were identified in DPR (37.5%) and none in the CBCT protocols (P > .05). The type of instrument (stainless steel hand file or reciprocating instrument) did not influence the identification of the separated instrument (P > .05). This study showed that DPR is the most accurate and sensitive imaging technique, with 83.3% and 37.5%, respectively. CONCLUSIONS: DPR is the better imaging diagnostic exam to evaluate the presence of separated endodontic instruments inside a root canal in comparison with the ICC, ICN, and PXD tomographic protocols. However, most of the separated instruments were not identified.

Root Preparation of Deciduous Teeth: Efficacy of WaveOne and ProTaper Systems with and without Passive Ultrasonic Irrigation.

INTRODUCTION: The aim of this study was to compare root preparation of deciduous teeth with WaveOne Large (WO) and ProTaper F4 (PT) instruments with or without passive ultrasonic irrigation (PUI). METHODS AND MATERIALS: Forty-eight deciduous teeth were scanned before and after root preparation and divided in four groups (n=12): WO+EDTA (WO); WO+EDTA with PUI (WOPUI); PTF+EDTA (PT); and PT+EDTA with PUI (PTPUI). Root canal enlargement by micro-computed tomography and root canal cleaning by scanning electron microscopy (SEM) were analyzed. Data were submitted to two-way ANOVA and Tukey's tests to analyze the root canal volume variation, and Kruskal-Wallis followed by Friedman and Wilcoxon tests were used to evaluate the cleaning efficacy. The level of significance was set at 0.05. RESULTS: No significant difference occurred in total volume between groups (P>0.05). On analysis by thirds of the root canal, there was a difference in volume between WO (cervical) compared to WO and PT (apical), and PTPUI (middle and apical) (P<0.05). When cleaning of the thirds within the same group was compared, there was a significant difference in all groups (P<0.05). Among the groups, in the thirds, in the cervical a difference occurred (P=0.028), and the pairwise comparisons indicated statistically difference between WO and PT, and WO and PTPUI (P<0.05). In the pairwise comparisons among thirds, in the groups, difrences occured in all of them when compared the cervical and apical thirds (P<0.05). CONCLUSION: Passive ultrasonic irrigation has not improved the smear layer removal in deciduous teeth. Despite the differences in performance between WO and PT instruments, both were suitable for preparation of deciduous teeth.

Objective: evaluate the association between periodontal disease, preterm births and low birth weight neonates in a group of women from the city of Curitiba, PR, Brazil. Methods: in this case-control study, an evaluation was conducted of 51 mothers aged 16-40 years divided into two groups: those with a preterm delivery and low birth weight babies, and those without a preterm delivery but with low birth weight babies. Data about the mothers and the neonates were collected via questionnaires and medical record analysis. Periodontal examination was performed at six sites of each tooth present, except for the third molars. Results: it was found that 82.4 percent of the women had had a normal delivery and 25.5 percent a preterm delivery. 19.6 percent of the babies weighed less than 2 500 g at birth, and 5.9 percent of the women had periodontal disease.
