RESUMO
PURPOSE: To compare the clinical effect of Er:YAG laser and turbine handpiece in the removal of lower horizontally impacted wisdom teeth, and to evaluate the operation time, postoperative pain, facial swelling, degree of mouth opening limitation and complications. METHODS: From March 2020 to May 2022, forty patients with bilateral lower mandibular horizontally impacted wisdom teeth in the Department of Oral and Maxillofacial Surgery of Linyi People's Hospital were selectedï¼and all bilateral wisdom teeth were partially bone buried. The bilateral wisdom teeth of each patient were removed by Er:YAG laser on one side and turbine handpiece on the other side, respectively. The patients were divided into experimental(laser) group and control(turbine handpiece) group according to the ways of bone removal on each side. The clinical effect of the two groups was compared after a week of follow-up. Statistical analysis was performed with SPSS 19.0 software package. RESULTS: There was no significant difference between the two groups in operation time(Pï¼0.05). The incidence of postoperative pain, facial swelling, mouth opening limitation and complications in the experimental group were significantly lower than those in the control group(Pï¼0.05). CONCLUSIONS: The operation time of extraction with Er:YAG laser is similar to that with turbine handpiece, but laser can reduce postoperative reaction and the incidence of complications, which is easy to be accepted by patients and worthy of wide application.
