Objective

This study was designated to evaluate postoperative pain in irreversible symptomatic teeth after different disinfection methods (Diode laser 810, PhotoDynamic Therapy, and sonic activation) using visual analogue scale.

Patients and methods

30 patients having symptomatic irreversible pulpitis in upper central incisors and canines were involved in the study. All canals were prepared with proTaper gold rotary files and irrigated with sodium hypochlorite during instrumentation. Cases were classified into three groups according to the final disinfection method used, ten patients each group ( n = 10). Group I: Root canals were disinfected with diode laser 810. Group II: Root canals were disinfected using PhotoDynamic Therapy. Group III: Root canals were treated using Eddy sonic activation. Postoperative pain was evaluated after 24, 72, and 1 week. Statistical analysis were analyzed using the Mann–Whitney U test. The significance level was set at P less than 0.05.

Results

In all groups, postoperative pain decreased by time in all time intervals. Group II showed the least postoperative pain experienced in all cases followed by group I then group III. There was no significant difference in postoperative pain among all groups.

Conclusion

Using diode laser 810 in root canal disinfection as adjunctive methods showed improvement in decreasing postoperative pain records than sonic activation method.
