摘　　要：Aim The purpose of the study is to compare the labial frenectomy between the laser surgery(erbium yttrium aluminum garnet and neodymium-doped yttrium aluminum garnet(Er:YAG and Nd:YAG))and the scalpel method.Methods The trial was a randomized controlled test.Thirty four patients aged from 5 to 10 years requiring the frenectomy were included in this study.Patients were randomly divided into two groups:group A:Er:YAG and Nd:YAG laser group and group B:scalpel group.In addition,this comparison considered the following factors:surgical time and Visual Analog Scale(VAS)pain score,which includes intraoperative pain,postoperative pain and complications,such as speaking and chewing,for 1 day and 7 days following labial frenectomy.After 3 months,we recorded the healing outcome by photos.Results There was a statistically significant difference in mean surgical time between laser surgery(mean=224±59 s)and scalpel surgery(mean=740±168 s).According to VAS scores of the intraoperative period(3 hours after the operation and 1st postoperative day of pain),chewing and speaking were statistically higher in group B than those in group A;but in the 7th postoperative day of pain,there was no significant difference in speaking and chewing.After 1 month,all of the patient results were recorded,including the healing of wound and scar.Except for one patient in group B who had a scar,all patients achieved good results.Conclusion Based on the results of this study,it can be concluded that Nd:YAG laser is an efficient and more comfortable alternative to the scalpel for a frenectomy in upper lip frenulum.
