AB - Introduction:
The aim of this study was to evaluate porcine palatal mucosa dissolution by sodium hypochlorite (NaOCl) with or without an auxiliary dissolving agent containing glycocholic acid and a mixture of surfactants (Keratobacter [KB]; Saint Joseph DID, Valencia, Spain).

Methods:
One hundred forty samples were obtained from porcine palatal mucosa and weighed using a high-precision balance. The samples were randomly divided into 4 experimental groups (n = 35) based on the test solution used: distilled water (the negative control), CanalPro NaOCl 6% (Coltene Whaledent, Altstätten, Switzerland), KB, and a 9:1 vol/vol mixture of NaOCl with KB (NaOCl + KB). After 5, 10, 15, and 20 minutes of immersion in the solutions at 27°C ± 1°C, the samples were weighted by a blinded assessor. The intergroup weight at the different time points was statistically analyzed using the analysis of variance test with the Bonferroni posttest.

Results:
All test groups presented with tissue dissolution although complete dissolution did not occur in any sample. The largest percent in weight reduction occurred between time points (t) = 0 minutes and t = 5 minutes for the NaOCl + KB group (22.5%) followed by KB (18.5%) for the same time period. NaOCl presented with similar tissue dissolution activity during the different time points, ranging from 7.8% (t = 10 minutes–t = 15 minutes) to 6.8% (t = 15 minutes–t = 20 minutes). Significant weight differences were found among the different experimental groups after 5, 10, and 15 minutes of incubation, with the only exception being KB versus NaOCl + KB. No significant differences were found when comparing the test groups at t = 20 minutes.

Conclusions:
The addition of KB to NaOCl increased porcine palatal mucosa dissolution in vitro.
