%X objective: the objective of this study was to evaluate changes in root dentin permeability of human teeth after chemical-surgical preparation, and laser irradiation with er: yag, nd: yag, through the use of the radioisotope technetium-99m (99mtc) free. materials and methods: thirty channels palatal roots of human maxillary first premolars were prepared and divided randomly into three experimental groups: g1 (control), g2 (laser irradiation with er: yag) and g3 (nd laser irradiation : yag). in the samples were deposited 99mtc free inside the root canal, enough to fill and placed in test tubes containing 1 ml of saline. after 1 hour, the account of the radioactive isotope (99mtc) was performed. results: after statistical analysis (anova) found that the best results in terms of decreased permeability were found in group 3, followed by group 2 and group 1. conclusion: we conclude that irradiation with nd: yag caused a significant decrease in the permeability of root canal dentin. laser er: yag and control in relation to the dentin permeability of root canal walls showed no statistically significant differences at 5%.
