Abstract:

Objectives: The objective of this study was to evaluate the efficacy of the single-cone gutta percha technique (SC) through visualization of voids in the mesial root canals of permanent mandibular molars.

Methods: Ten mandibular molars with fully developed roots containing two mesial canals were instrumented using rotary and hand files. The mesial roots were then obturated using the SC technique with bioceramic sealer. The use of a high-powered microscope allowed for visual analysis of sealer adaptation to the root canal wall, sealer adaptation to the gutta percha, the presence of voids, and, when present, the fluidity of sealer and gutta percha into fins, lateral canals, or isthmi. The data was analyzed by comparing the area of voids to the total area of the root canal system in apical and middle cross sections.

Results: When obturating the mesial canals of mandibular first molars, the SC obturation technique will produce about 5.77255% voids relative to the total area of densely filled canal space.

Conclusions: The results of this study can be used to encourage dental professionals to perform SC as the obturation technique of choice in the mesial canals of mandibular permanent molars.
