Electro-acupuncture application may benefit in reducing pain after periodontal flap surgery: Study

Electroacupuncture was applied bilaterally to the Hegu (LI4), Daying (ST5), and Jiache (ST5) points of the patients in the EA group immediately before and after the flap surgery for 30 min at a frequency of 50 Hz to each point at a current that the patient could tolerate. The patients in the control group underwent flap surgery without applying electroacupuncture.

Patients were asked to record their pain levels on the visual analog scale and the number of analgesic tablets they took during the 7 postoperative days on the given form. RESULTS: The total mean score of pain felt in the EA group (16.60 ± 2.78) was found to be significantly lower than that in the control group (31.37 ± 2.78) (P = 0.001). No significant difference was found between the groups regarding the amount of analgesics taken.

The study shows that electro-acupuncture application is beneficial in reducing pain after periodontal flap surgery. Overall, more research is needed to understand the effects of electro-acupuncture on postoperative pain fully.
