Evaluation of pH and calcium ions release of two tricalcium silicate-based sealers through roots of primary teeth.

BACKGROUND

This study aimed to evaluate the pH and calcium ions (Ca) release from two tricalcium silicate-based sealers (Sealer Plus BC and Bio-C Pulpecto) through roots of primary teeth.

METHODS

Forty root canals of primary incisors were prepared and distributed into four groups according to the filling material: G (Sealer Plus BC); G (Bio-C Pulpecto); G (Ultracal); and G (no filled). pH measurement was performed with a digital pH meter, and the Ca+ release was measured in an atomic absorption spectrophotometer at baseline, 24 h and 1, 2, 3, and 4 weeks later. The data were analyzed using two-way ANOVA and Tukey's post hoc tests.

RESULTS

The results did not reveal significant differences between the groups in terms of pH in 24 h, 1-, and 2-weeks' periods. After 4 weeks, there was a significant difference, with the highest mean pH values in G, followed, respectively, by G and G. Regarding the Ca+ release, the G showed greatest mean values at all evaluated times, and the other groups showed no difference between them.

CONCLUSION

Both sealers were able to promote the elevation of the pH and Ca+ release through roots of primary teeth, which brings favorable properties for their use as a filling material.
