AIM: Compare the dissolution capacity of organic tissue of two solutions (NaOCl and HOCl), subjecting them to different protocolsoftimeandtemperature. MATERIALS AND METHODS: For the present study 120 samples of bovine tissue were obtained ex vivo, which were divided into 10 groups of 12 samples each. Four NaOCl solutions were used at concentrations of: 5.25%, 2.5%, 1% and 0.5% respectively and a solution of 5% HOCl. Samples were observed at different time intervals: 1 minute, 5 minutes, 15 minutes, 30 minutes, 45 minutes and 60 minutes. The data collected from the observations were based on macroscopic changes present on the surface of each sample and were subsequently analyzed statistically indifferent tests. RESULTS:The data were analyzed with the software Statistica 7.0. Analysis 1 compared at different time intervals, the dissolution capacity of organic tissue between the different concentrations of NaOCl and HOCl, within 5 minutes and 15 minutes, they did not show significant differences, while within 30 to 60 minutes, significant differences were observed. In the second part of the statistical analysis, the evaluation between the two temperatures with 21oC and 37oC were compared at the different time intervals, the results obtained for the 1 minute, 45 minute and 60 minute times did not allow to observe significant differences. For the 5-minute, 15-minute and 30-minute intervals, differences were better observed; always in samples treated at 37ooC.
