Effect of Three Filling Techniques Using Gutta-Percha and Bioceramic-Based Sealer on Apical Leakage Levels in Roots with Different Apical Foramen Sizes

Author(s): Esma Dinger* and Emre Bodrumlu

Abstract

Aim: This in-vitro study aimed to evaluate the effect of three different filling techniques on apical leakage in roots with various apical foramen diameters, using gutta-percha and bioceramic-based root canal sealers. Method: A total of 160 extracted maxillary anterior teeth were divided into four main groups of teeth based on the apical foramen diameters. The apical foramen diameters of 0.30 mm, 0.40 mm, 0.50 mm, and 0.80 mm were prepared using a 30 #K, 40 #K, 50 #K, and 80 #K type hand file, respectively. Following root canal preparation was completed with adjusted rotary system and root canals were filled using gutta-percha and Well Root ST bio ceramic sealer. The samples were then divided into 3 subgroups as filling techniques the single cone, the lateral condensation, and the thermoplastic injection. The amount of apical leakage of the samples was evaluated using the dye penetration technique. Result: The amount of apical leakage varied according to apical diameter and filling technique used. The greatest leakage occurred in the teeth filled using the single-cone technique with an apical diameter of 0.80 mm (80.74 ± 0.45) and the least leakage occurred in the teeth filled by using the single cone technique with an apical diameter of 0.30 mm (2.821 ± 0.28). There was a significant difference between the groups (p<0.05) Conclusion: In teeth with smaller apical diameters, less apical leakage occurred. The filling technique affects the amount of apical leakage differently depending on the apical diameter of the tooth.
