Histomorphometric Analysis Of Pulp Submitted To The Action Of Bromelain Associated With Irrigation Solutions

Aim: The objective of this study was to evaluate the tissue disgregation capacity of pulp in different solutions associated or not with bromelain.Methodology Fifty bovine mandibular incisors were used, divided into five groups: C: Control, H: sodium hypochlorite 2.5%, B: bromelain, BL: bromelain + L-cysteine, BH: bromelain + sodium hypochlorite 2.5%. The pulp fragments were stored at -20 degrees C, washed with saline solution and moved to 25 degrees C in eppendorf tubes with 1 ml of each substance. For the histomorphometric evaluation, the pulp fragments were prepared as histological routine, observed with optical microscopy and evaluated using ImageJ 1.49 software.Results: The histomorphometric results showed that, in C: there was no alteration per tissue; H: there was a peripheral and central tissue disintegration; B: there was a protein and cellular degradation pattern, from the peripheral to the central area; BL: there was a central degradation. In BH, showed an effect enhanced by bromelain, when related to sodium hypochlorite, showing greater tissue degradation.Conclusions: The association of bromelain with sodium hypochlorite potentiated the disintegration action of the pulp, opening possibilities for several clinical applications.
