Abstract

Abstract: Objective: To analyze the short-term efficacy of pulsed Nd:YAG laser-assisted treatment on pericoronitis during pregnancy and its effect on dental anxiety in pregnant women. Methods: 68 patients with mild pregnancy-associated pericoronitis during the alveolar surgery from September 2017 to May 2019 were collected and randomly divided into two groups (n=34) according to the order of treatment. The treatment period was one week. The non-laser group was given conventional pericoronal irrigation and the laser group was given adjuvant therapy with pulsed Nd:YAG laser. The pain degree (NRS), mouth opening, gingival index (GI), bleeding index (BI), MDAS score, total effective rate, recurrence rate, and pregnancy outcome were compared between two groups. Results: The mouth opening degree, NRS, GI, and BI of the laser group were improved compared with the control group on the 2nd-5th days (P<0.05), however, no difference on the 1st and 7th days (P>0.05). The number of DA in the laser group was lower than that in the non-laser group on the first time of treatment (P<0.01). After 1 week, the total effective rate of the laser group was greater than that of the non-laser group (P<0.05). After 6 months, the recurrence rate in the laser group was lower than that in the non-laser group (P<0.05). None of the 68 patients had adverse pregnancy outcome. Conclusion: Pulsed Nd:YAG laser-assisted treatment has significant short-term efficacy on mild pregnancy-associated pericoronitis. It is safety and can alleviate dental anxiety in pregnant women.
