Objectivo: O presente estudo teve como objetivo a parametrização do material obturador removido durante o retratamento endodôntico, bem como a quantificação dos detritos extruídos pelos diferentes sistemas de instrumentação em análise.
Materiais e Métodos: 40 dentes monocanalares, com Tratamento Endondôntico prévio, foram selecionados e divididos em 2 grupos (n=20) de acordo com os sistemas em teste: Reciproc 25® (VDW, Munich, Germany) e Reciproc 25® adjuvado pela lima Xp-Endo Finisher® (FKG, La Chaux de Fonds, Switzerland). Todos os dentes foram digitalizados pela técnica “Cone-Beam Computed Tomography”, antes e depois da remoção do material obturador. Foi calculada a área do material obturador remanescente recorrendo ao software de análise Adobe Photoshop CC 2015®, de forma a poder inferir, dados sobre a eficácia da remoção.
Os detritos extruídos pelo Foramen Apical foram coletados para Tubos de Eppendorf, sendo que, para cada dente, a sua quantidade foi pesada.
Os dados obtidos foram colocados em tabelas do Microsoft Excel e analisados estatisticamente recorrendo ao GraphPad Prism® versão 5.00 para Windows, GraphPad Software, San Diego Califórnia. O nível de significância foi fixado em 5% para todos os testes (p < 0,05).
Resultados: Não houve diferenças significativas na remoção de material obturador entre os sistemas em teste. A XP-Endo Finisher® originou maior quantidade de detritos extruídos.
Conclusões: A XP-Endo Finisher® não contribuíu para uma melhor remoção de material obturador e promoveu uma maior extrusão apical de detritos.
Objective: The present study aim to parameterize the filling material removed during Endodontic retreatment, as well as to quantify the debris extracted by the apical foramen during the use of different systems. Material and Methods: 40 single-canal teeth with Endodontic treatment were selected and divided into 2 groups (n = 20) according to the systems in test: Reciproc 25® (VDW, Munich, Germany) and Reciproc 25® supplemented by XP-Endo Finisher® (FKG, La Chaux de Fonds, Switzerland). All teeth were scanned by a Cone-Beam Computed Tomography technique before and after the filling material’ removal. The total area of the remaining filling material was measured using the analysis software Adobe Photoshop CC 2015®, in order to infer data about the efficiency of the technique in test. The debris extracted by the Apical Foramen were collected into Eppendorf Tubes and, for each tooth, its amount was weighed. All data collected were organized into Microsoft Excel tables and, then, statistical analysed using GraphPad Prism® version 5.00 for Windows, GraphPad Software, San Diego California. The level of significance was set at 5% for all the tests (p < 0.05). Results: There were no significant differences in the removal of filling material between the systems in test. XP-Endo Finisher® produced more apical debris extrusion. Conclusions: XP-Endo Finisher® did not contribute to a better removal of filling material and promoted more apical debris extrusion.
