Summary

Main Purpose: To evaluate the effect of photodynamic therapy on soft tissue healing after tooth extraction at periodontal infection site, and to compare the effect on pain degree and bone tissue remodeling after tooth extraction.

Conditions

  • Periodontitis

Interventions

DRUG

Dental diode laser device Paiwei™（Zhengzhou Gata biotechnology Co.,Ltd.,China） which was 650-670nm with a power of 160mw-220mw.

The tooth extraction sockets were filled with photosensitizer methylene blue. The guide head of the laser periodontal therapy instrument (Dental diode laser device Paiwei™（Zhengzhou Gata biotechnology Co.,Ltd.,China） which was 650-670nm with a power of 160mw-220mw.) was placed in the tooth extraction sockets to probe and move around the tooth extraction sockets for 1 minute. At the end of irradiation, a cotton ball dipped in saline was used to wipe the guide head and rinse the photosensitizer out of the socket
