RESUMO
Objective To investigate the clinical effect of minimally invasive extraction of anterior tooth residual root after root separation.Methods A total of 400 patients receivinganterior tooth residual root extraction were collected in the clinic of oral and maxillofacial surgery department between January 2015 and December 2016.The patients were divided into a control group and a study group according to their sequence to see the doctor,with an odd for the study group and an even for the control group.In the study group,residual roots were separated mesiodistally by high speed turbine before using minimally invasive extraction tool;while in the control group residual roots were extracted only using minimally invasive extraction tool.The surgical duration,postoperative damage rate of the lip side plate,degree of pain and patient satisfaction in the two groups were analyzed.Results The surgical duration was shorter in the study group compared with the control group (P ＜ 0.05).The postoperative damage rate of the lip side plate and the degree of pain were lower,while patient satisfaction was higher in the study group than in the control group (P ＜ 0.05).Conclusions The postoperative damage rate of the lip side plate is significantly lower in minimally invasive extraction of anterior tooth residual root after root separation.Smaller trauma is conducive to the implant afterwards.Root separation in minimally invasive extraction of anterior tooth residual root is valuable for clinical application.
