RESUMO
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.
ABSTRACT Objective To evaluate the user's profile and waiting time for endodontic treatment at the Center of Dental Specialties (CDS) Positivo, located in the city of Curitiba, PR. Brazil. Methods This is a cross-sectional study using primary data from 77 patients queue specialty of Endodontics, from March to July 2017. Data collected were: waiting time, sex, age, referenced teeth and number of referrals per Public Service Health Unit. Results The mean waiting time was approximately 11 months. Of the total, 56% were female, with a mean age of 35.5 years. The most referenced teeth were the lower posterior. Conclusion Waiting time in queue is considered long, which requires a greater dialogue with the primary attention for the formulation of strategies aimed at the reduction of the oral diseases and the greater professional capacity for the diagnosis and the conduction of the cases.
RESUMEN Objetivo Evaluar el perfil de usuario y el tiempo de espera para tratamiento endodóncico en el Centro de Especialidad Odontológica (CEO) Positivo, localizado en la ciudad de Curitiba, PR. Brasil. Métodos Este estudio transversal utilizó datos primarios de 77 pacientes en lista de espera para la especialidad de Endodoncia, de marzo a julio de 2017. Los datos recolectados fueron: tiempo de espera, género, edad, dientes referenciados y cantidad de encaminamientos por Unidad de Salud del Servicio Público. Resultados El tiempo promedio de espera fue de aproximadamente 11 meses. Del total, 56% eran del género femenino, con promedio de edad de 35,5 años. Los dientes más referenciados fueron los postero-inferiores. Conclusión El tiempo en la lista de espera es considerado largo, lo que requiere mayor diálogo con la atención básica para la formulación de estrategias dirigidas de reducción de las enfermedades bucales y la mayor capacitación profesional para diagnóstico y conducción de los casos.
RESUMO
INTRODUCTION: The aim of this study was to evaluate the effect of the order of preparation of four-canal maxillary molars on volume variation, instrument deformation, cyclic fatigue, and preparation time by using the WaveOne Gold Primary (WOG 25.07). METHODS: We selected 48 permanent, human, four-canal maxillary molars. The teeth were divided into 4 groups according to the order of initiation of the canal preparation sequence: (1) mesiobuccal (MB), distobuccal (DB), palatal (P), second mesiobuccal (MB2); (2) DB-P-MB2-MB; (3) P-MB2-MB-DB and (4) MB2-MB-DB-P. Pre- and post-preparation microtomography scanning was performed to obtain initial and final canal volume measurements. The instruments were also evaluated by using scanning electron microscopy to determine the wear and deformation present after use. The active instrumentation time was also recorded. The data were statistically compared by using a significance level of 5%. RESULTS: No statistically significant difference was found between groups for volume variation and time of preparation of the canals with the WOG system (P > .05); however, a statistically significant difference was observed in the deformation of the instruments. In the comparison between the groups for MB-DB-P-MB2 and P-MB2-MB-DB, the latter presented greater deformation of the instruments. CONCLUSIONS: Root canal preparation sequence affected deformation of the instruments but did not influence the volume variation or the canal preparation time with the WOG system. To minimize instrument deformation, the preparation order should be MB-DB-P-MB2.
