Comparación de la penetración en los túbulos dentínales en el tercio apical de dos cementos endodónticos, BioC Sealer® y AH-Plus® mediante microscopio electrónico de barrido. (SEM): un estudio in vitro

Abstract

Tight three-dimensional obturation of root canals is essential for the success of endodontic treatment, since it prevents reinfection by microorganisms. Sealing cements play a fundamental role in this process. This in vitro study compares the penetration capacity of two endodontic cements, BioC Sealer® and AH-Plus®, into the dentinal tubules of the apical third by means of scanning electron microscopy (SEM). Objective: to evaluate and compare the penetration distance in the dentinal tubules of BioC Sealer® and AH-Plus® in the apical third, determining which of the two cements offers a better seal. Methods: thirty human uniradicular teeth were selected and randomly divided into two groups of 15 teeth, one filled with BioC Sealer® and the other with AH-Plus®. The samples were processed, and the penetration of the cements into the dentinal tubules was measured in microns using SEM. Statistical analysis included the t-test for independent samples. Results: both cements showed penetration into the dentinal tubules, the average penetration being 285.87 μm for AH-Plus® and 265.97 μm for BioC Sealer®. However, no statistically significant difference was found between the two cements (p-value = 0.185). Conclusions: both BioC Sealer® and AH-Plus® offer adequate penetration into the dentinal tubules of the apical third. Although AH-Plus® showed slightly better penetration, this difference was not significant, suggesting that both cements are viable options for endodontic treatment.
