ABSTRACT

Objective: The aim of this study was to determine the correlation between the diameter D0 of guttapercha points from three different commercial brands (Tanari Man, Cone Tech and Dentsply) and their original respective values. Materials and methods: A high precision micrometer was used by a single calibrated operator to evaluate if the gutta-percha points are in aggrement with the n. 57 ANSI/ADA specification. Results: For the 0.04 tapered points, Cone Tech showed lower percentage of inadequate points (52%), followed by Dentsply (56%) and Tanari (80%). For the 0.06 tapered points, Cone Tech showed lower percentage of inadequate points (50%), followed by manufacturers Dentsply (53%) and Tanari (81%). Conclusions: It can be concluded that there is no standardization in the diameter D0 of the gutta-percha points of different commercial brands.


Objetivo: O objetivo deste estudo foi determinar a correlação entre o diâmetro D0 dos cones de guta-percha detrês diferentes marcas comerciais (Tanari Man, Cone Tech e Dentsply) com seus respectivos valores originais. Materiais e métodos: Um micrômetro de alta precisão foi utilizado por um único operador devidamente calibradopara avaliar se os cones de guta-percha estavam de acordo com a norma n. 57 da ANSI/ADA. Resultados:Para a conicidade 0.04, Cone Tech apresentou menor percentual de cones inadequados (52%), seguido deDentsply (56%) e Tanari (80%). Para a conicidade 0.06, Cone Tech apresentou menor percentual de conesinadequados (50%), seguido de Dentsply (53%) e Tanari (81%). Conclusões: Pôde-se concluir que não há padronizaçãono diâmetro D0 dos cones de guta-percha das diferentes marcas comerciais.
