Abstract Objective To valuate the effect of photodynamic on pericoronitis treatment. Methods As the study group, 108 patients ramdomly recruited from 211 cases of pericoronitis were given local rinse and photodynamic therapy, and the other patients as the control group were given local rinse and iodine glycerin therapy. On the third day, the curative effect were compared. Results In the study group,the therapy was effective in 98 patients and was ineffective in 10 patients. In the control group ,the therapy was effective in 81 patients and ineffective in 22 patients. The studygroup(90.74%) gained more notable effect than the contrast group(78.64%), with statistically significant difference(P<0.05). In the study group, the therapy was effective in 61 patients and ineffective in 2 patients whose depths of pericoronal pockets were 2.5～4.0 mm.The therapy was effective in 37 patients and ineffective in 8 patients whose depths of pericoronal pockets were 4.1～5.5 mm, the efficacy in the former was higher than in the latter,with statistically signficant difference(P<0.05). Conclusions Treatment ofpericoronitis with photodynamic deserves popularizing. The depth of pericoronal pockets and treatment efficacyare positively correlated.
