Abstract

Abstract: Objective: To learn the effect of photodynamic therapy(PDT) on promoting pain relief after pulpotomy combined with stainless steel preformed crowns(SSC)in children. Methods: Thirty pairs of teeth restored with SSC were selected, which were divided into photodynamic therapy and control groups, using an autologous tooth as the control. The children were followed up at 6 h, 24 h, and 72 h after restoration. Results: At 6 h after SSC, the incidence of pain was 20% and 10% in the control group and the experimental group, respectively, and the incidence of pain was 60% and 56.67% in the two groups at 24 h after surgery, respectively, and the pain scores and pain levels in the experimental group were lower than those in the control group (P<0.05). However, the differences between the two groups were not statistically significant at 72 h after surgery (P>0.05). Conclusion: Photodynamic interventions after SSC can effectively relieve post-operative pain symptoms.

Key words: stainless steel crown, post-operative pain, photodynamic therapy
