Dentinal defect formation during root canal preparation by Trunatomy files with and without the glide path

ABSTRACT Objective: The aim of the present study is to evaluate the occurrence of dentinal defects on the apical surface after rotary instrumentation at different working lengths with Trunatomy Prime system, with or without the use of a glide path file. Methods: Twenty human single-rooted mandibular...

Summary:ABSTRACT Objective: The aim of the present study is to evaluate the occurrence of dentinal defects on the apical surface after rotary instrumentation at different working lengths with Trunatomy Prime system, with or without the use of a glide path file. Methods: Twenty human single-rooted mandibular premolars were selected and divided into 2 experimental groups (n=10). GTP group (Glide Path + Trunatomy Prime), the TP group (Trunatomy Prime). Results: To check the agreement between the examiners, the Kappa test was performed. Subsequently, the results were subjected to the Shapiro-Wilk normality test. The sample showed abnormal behavior and were subjected to the non-parametric Mann Whitney test with a significance level of 5%. No significant difference was found between the groups. Conclusion: It is concluded that there was no causal relationship with the formation of dentin defects with and without the use of glide path files at different limits of instrumentation with Trunatomy files. RESUMO Objetivo: O objetivo do presente estudo é avaliar a ocorrência de defeitos dentinários na superfície apical após instrumentação rotatória em diferentes comprimentos de trabalho com o instrumento Trunatomy Prime, com ou sem o uso de lima glide path. Métodos: Vinte pré-molares inferiores humanos unirradiculares foram selecionados e divididos em 2 grupos experimentais (n=10). Grupo GTP (Glide Path + Trunatomy Prime), grupo TP (Trunatomy Prime). Resultados: Para verificar a concordância entre os examinadores, foi realizado o teste Kappa. Posteriormente, os resultados foram submetidos ao teste de normalidade de Shapiro-Wilk. A amostra apresentou comportamento anormal e foi submetida ao teste não paramétrico de Mann Whitney com nível de significância de 5%. Não foi encontrada diferença significativa entre os grupos. Conclusão: Conclui-se que não houve relação causal com a formação de defeitos dentinários com e sem o uso de instrumentos de glide path em diferentes limites de instrumentação com instrumentos do sistema Trunatomy.
