摘要: PURPOSE: To evaluate the bovine pulp tissue dissolution ability of photodynamic therapy. METHIDS: Twenty pieces were weighed and divided randomly into four groups (n=5), according to cleaning protocol: G1 - distilled water (negative control), G2 sodium hypochlorite 1% (positive G3 therapy, G4 + The observation events was performed by two observers blinded in relation test using 2x magnification, recording time minutes until complete dissolution. total 2 hours. rate calculated dividing weight fragment (mg) (mg/min). RESULTS: Only group (NaOCl) able promote tissue. In other there no occurrence samples. mean for samples from 1.26 mg/min. CONCLUSION: dissolve fragments therapy does not show
