Abstract(s)
Objetivo: O objetivo deste estudo foi avaliar a filtração apical em dentes obturados com 2 cimentos: cimento à base de resina epóxi e cimento biocerâmico e com 3 técnicas de obturação; cone único, condensação lateral e híbrida de Tagger.
Materiais e métodos: Dentes monocanalares foram instrumentados com ProTaper Gold®. Os dentes foram divididos em seis grupos: Dois grupos para cada técnica utilizando os dois cimentos e finalmente, dois grupos controle não obturados. Após imersão em azul metileno os dentes foram finalmente cortados de modo a medir a filtração apical. Os resultados foram registrados e analisados estatisticamente.
Resultados: Os resultados descritivos relacionados à filtração apical mostram que a penetração do corante nos Grupos I, II e III foi maior do que nos Grupos IV, V e VI. Nos grupos obturados com o mesmo tipo de cimento, os grupos III e VI apresentaram menor filtração apical.
Conclusão: A técnica híbrida de Tagger proporcionou melhor selamento apical em comparação com a técnica de condensação lateral e a técnica de cone único e o cimento biocerâmico proporcionou menor filtração apical do que o cimento à base de resina.
Aim: The aim of this study was to evaluate apical leakage in teeth obturated with 2 cements: epoxy resin-based cement and bioceramic cement and with 3 filling techniques; single cone, lateral condensation and Tagger's hybrid. Materials and methods: Single-root teeth were instrumented with ProTaper Gold®. The teeth were divided into six groups: Two groups for each technique using the two cements and finally, two control groups. After immersion in methylene blue the teeth were finally cut in order to measure the apical filtration. The results were recorded and statistically analyzed. Results: The descriptive results related to apical filtration show that the penetration of the dye in Groups I, II and III was higher than in Groups IV, V and VI,. In groups obturated with the same type of cement, Groups III and VI showed less apical leakage. Conclusion: Tagger's hybrid technique provided better apical sealing compared to the lateral condensation technique and the single cone technique, and the bioceramic cement provided less apical leakage than the resin-based cement.
