Application of high-speed turbine handpiece in extraction of impacted third molar in lower mandible and its influence on patients'mouth opening limitation
Objective To investigate the application of high-speed turbine handpiece in the extraction of the third mo-lar impacted in the lower mandible,and observe the extraction situation of the affected tooth,the degree of limitation of the patient's mouth opening and the occurrence of complications.Methods A total of 120 patients with low impacted mandibular third molar extraction who were admitted to the Stomatology Department of Zhengzhou Yihe Hospital from Au-gust 2021 to August 2023 were randomly divided into the observation group and the control group,with 60 patients in each group.The control group underwent bone chisel and split crown extraction,while the observation group applied high-speed turbine handpiece to sharpen the crown,extrate the tooth and extract the affected tooth.The degree of post-operative mouth opening limitation,postoperative pain and complications were compared between the two groups.Results The extraction time of control group[(24.21±3.11)min]was longer than that of observation group[(17.08±2.19)min](P＜0.05).VAS score of observation group(2.27±0.73)was lower than that of control group(3.70±0.66),and the difference was statistically significant(P＜0.05).The mouth opening limitation of pa-tients in the observation group was significantly lower than that in the control group(P＜0.05).The total complication rate of observation group(3.33％)was lower than that of control group(P＜0.05).Conclution The use of high-speed turbine handpiece to extract the affected teeth in patients with mandibular low third molar obstruction can improve the surgical efficiency and reduce the degree of pain of the patients,alleviate the postoperative mouth opening limitation,and has a high degree of safety,which is worthy of clinical promotion.
