COMPARATIVE EVALUATION OF OBTURATION QUALITY OF FIVE DIFFERENT OBTURATING TECHNIQUES USING CONE BEAM COMPUTED TOMOGRAPHY- AN IN VITRO STUDY

Abstract

Introduction: The proper obturation of the root canal system is a key factor in achieving successful results in endodontic treatments. Achieving a fluid-tight seal is the ultimate goal of the obturation technique using gutta-percha and sealer.

Aim: To evaluate the quality of obturation done by five different obturation techniques.

Material and Methods: A total of 50 mandibular premolars with single roots were selected. Biomechanical preparation was done by Wave one Gold file of medium size. Teeth were allocated into five groups of 10 teeth each according to the obturation technique, i.e., Lateral compaction, Vertical compaction, Thermafil, Injection Technique, and Continuous wave compaction. Cone beam computed tomography was employed to measure filling area and voids at the coronal, middle and apical third of the root canal following obturation by different techniques. Obturation time was calculated using Stopwatch. The data was statistically analyzed by One Way ANOVA test followed by Tukey HSD for multiple comparisons.

Results: The continuous wave of compaction technique resulted in more amount of filling area and the least number of voids. Least time for obturation was observed with the Thermafil. Conclusion: The Continuous Wave of Compaction may be a good alternative for the great quality of 3D obturation, and it may be beneficial in obtaining the fluid tight seal in endodontically treated teeth. Thermafil technique showed the least time for obturation. Further, In vivo research is required in endodontically treated teeth.
