Abstract：Objective To explore the responses of patients with all types of burning mouth syndrome to low-level laser therapy.Methods Totally 90 BMS patients were randomly divided into 3 groups,30 cases in each group.Group A and B were treated with low-level laser,and therapeutic regimens were one time a day for continuous irradiation of 20 days (group A),and every other day for ten times (group B),respectively.Group C was treated with non-irradiation light,one time a day for continuous irradiation of 20 days.Group A,B and C were all given routine medication.Before and after the treatment and in the one-month follow-up,the pain (VAS score) and the total effective rates were measured.Results Statistically significant difference (P ＜ 0.05) was found between group A and B in the change of VAS after treatment,and the total effective rates of group A and B were significantly higher than that of group C.The total effective rate of type 2 BMS was significantly higher than that of type 1 and 3.There was no significant difference among groups and types of BMS in the VAS scores and the total effective rates between one-month follow-up and after the treatment (P ＞0.05).Conclusion Low-level laser is effective in the treatment of BMS,especially for type 2.In a certain period of time,there is no difference in the effect with different irradiation times under the same irradiation dose parameters.
