Abstrakt: Objective: The aim of this study is to evaluate the effect of sodium hypochlorite solvent solutions on bovine pulp tissue by analyzing products commercialized in Pelotas/RS, Brazil. Methods: The following substances were tested: Dakin's solution, Milton's solution, Labarraque's solution and double-strength chlorinated soda (5% sodium hypochlorite). Prescriptions were given out by compounding pharmacies and solutions were bought in dental supply stores. Four hypochlorite-based bleaches (Qboa, Clorofina and Brilhante), three bought at ordinary grocery stores and one solution prepared in a compounding pharmacy, were also evaluated. To test tissue dissolution, a peristaltic pump with 15 ml sodium hypochlorite was used. Bovine pulp fragments, previously sectioned into 10 mm slices from their central portion, were inserted into the pump. Pulp dissolution data were tested for normality by means of Anderson-Darling test which directed towards parametric and nonparametric tests. Results: 5% sodium hypochlorite proved to have the greatest pulp tissue dissolving ability. Dakin's solution proved the lowest while 2.5% and 2.0 to 2.5% products had intermediate bovine pulp dissolving ability. The ability to dissolve bovine pulp tissue was not observed in all samples tested. [ABSTRACT FROM AUTHOR]
