Effectiveness evaluation of three obturation techniques in the filling of a simulated internal root resorption area

Objective: This study aimed to analyze the effectiveness of three filling techniques for experimental cavities with internal root resorption. Methods: A total of 30 artificial maxillary central incisors with a standardized simulated cavity with internal resorption in the middle third of the root canal were used. After preparation, the teeth were randomly divided into three experimental groups according to the filling technique used: McSpaddenTM compactor (group 1), ultrasound (group 2), and Term Pack WLTM (group 3). Endodontic filling of the internal resorption cavity was verified via radiography in two views: mesiodistal and buccolingual. For analysis of the filling area, Image ToolTM software was used. Data were statistically analyzed by ANOVA, followed by Tukey’s test, with 5% significance level. Results: Analysis of the three filling techniques revealed the use of McSpaddenTM compactor and Term Pack WLTM provided better filling of the resorption cavity than that shown by the use of the ultrasonic spreader. Conclusion: Only McSpaddenTM compactor and Term Pack WLTM completely filled the internal root resorption cavity with root canal filling material.
