The Effect of Different Filling Techniques on the Penetration of AH Plus Bioceramic Paste into Lateral Canals
Abstract
Objective
Lateral canals in root canals can cause infection and apical periodontitis, which can complicate endodontic treatment and affect treatment outcomes. The aim of the study was to evaluate the penetration of AH Plus Bioceramic root canal obturating sealer into lateral canals, using different obturation techniques on 3D-printed teeth.
Method
The study used 45 3D-printed lateral incisors with a working length of 22 mm, an apical tip diameter of 0.30 mm and a lateral canal diameter of 0.15 mm at a distance of 3 mm from the apex. All canals were prepared with Endoart Touch Gold files to a size of 35/0.06. The canals were irrigated with distilled water during preparation. After preparation, the main and lateral canal openings were checked with a #10 K file. Teeth were randomly divided into three groups according to obturation technique: Single cone method (n = 15), cold lateral condensation (n = 15) and warm vertical condensation (n = 15). The teeth were obturated with AH Plus Bioceramic root canal filling paste and gutta-percha. After obturation, the teeth were radiographed and scored. The results were statistically analysed using Kruskall-Wallis and Mann-Whitney U tests and a significance level of p < 0.05 was accepted.
Results
The obturation technique affected the penetration depth of the AH Plus Bioceramic root canal filling paste into the lateral canals. When the warm vertical compaction technique was used, the root canal filling paste penetrated better into the lateral canal.
Ethical Statement
No human or animal-derived materials were used in this study. As this study was conducted on 3D-printed teeth, ethical committee approval was not deemed necessary.
