In vitro study of solubilization ability of bovine pulp tissue using different irrigating solutions

Resumo

The aim of this study was to evaluate in
vitro the capacity of solubilization of bovine pulp tissue, promoted by
the following auxiliary chemical solutions: 2.5% sodium hypochlorite
at pH 9, 5.25 % sodium hypochlorite at pH 9, 2% chlorhexidine gel at
pH 6, 17% EDTA at pH 7, and Smear-Clear®. Material and methods:
A total of ten specimens of bovine pulp tissue, weighing 1.65 g each,
were placed into flasks connected to a device developed for the
study in order to reproduce irrigation dynamics. The flasks with the
specimens received a volume of 80 ml of irrigating solution and the
experimental times were 15, 30, 45 and 60 minutes. Results: The
results were analyzed statistically by Kruskal-Wallis test to compare
the different experiment times (15, 30, 45 and 60 minutes) of each
irrigating solution. To compare the variation among the times of one
solution, Kolmogorov-Smirlov test (Lilliefors) was used. Conclusion:
Considering the results obtained and the limitations of the study,
it can be concluded that 5.25% sodium hypochlorite exhibited the
greatest solubilization ability, followed by 2.5% sodium hypochlorite,
Smear-Clear®, 17% EDTA and 2% chlorhexidine gel.
