- Analysis of apical fitting of .06 and .02 tapered gutta-percha master cones in root canals shaped with ProTaper rotary system Manoel Eduardo de Lima Machado Cleber Keiti Nabeshima Guilherme Henrique Rosa Martins Maria Leticia Borges Britto Medicina Endodontics gutta percha root canal preparation Introduction: The fitting of gutta-percha master cone is important for the obturation step. The modified single-cone technique using larger taper has provided better filling of gutta-percha than the original single-cone technique. Objective: The aim of this study was to verify if either .02 or .06 tapered gutta-percha master cone would better fit into the working length of teeth shaped using ProTaper rotary system. Material and methods: Thirty distobuccal root canals of mandibular molars were shaped using F2 ProTaper, and size 40, 35, 30 and 25 0.6 or 0.2 tapered gutta- percha cones were tested. The best fitting into the working length was recorded. The data were gathered and compared with size 25 by using Fisher’s exact test. Results: There was no statistically significant difference between groups (p = 0.4915). Sizes 30 and 35 were the most used. Conclusion: It can be concluded that both .02 and .06 tapered gutta-percha master cones showed best fitting in sizes larger than 0.25 mm in root canals shaped with ProTaper F2. 2013 artículo científico 1806-7727 https://www.redalyc.org/articulo.oa?id=153028468005 en http://www.redalyc.org/revista.oa?id=1530 RSBO Revista Sul-Brasileira de Odontologia application/pdf Universidade da Região de Joinville RSBO Revista Sul-Brasileira de Odontologia (Brasil) Num.3 Vol.10
