Multivariate analysis of factors affecting the operative time of a single impacted supernumerary tooth in the maxillary incisor region
摘要
Abstract
Objective:To investigate the factors influencing the operative time for the removal of a single impacted supernumerary tooth in the maxillary incisor region,and to provide a reference for pre-operative difficulty assessment.Methods:Clinical data were collected from 154 patients who underwent extraction of a single impacted supernumerary tooth in the maxillary incisor region at the Hospital of Stomatology,Hebei Medical University,from January to December 2023.All patients received a pre-operative cone beam CT(CBCT)examination,and surgeries were performed under general anesthesia.Patient age,sex,tooth morphology,orientation,position,root development status,surgeon's years of experience,and operative time were recorded.Multiple linear regression analysis was used to identify independent factors influencing operative time.Results:Patients'ages ranged from 4 to 21 years,with a mean of(9.03±3.11)years.Operative time ranged from 5 to 70 minutes,with a mean of(26.00±12.15)minutes.Multivariate analysis showed that patient age(B=1.175,P<0.05),vertical position(B=-5.417,P<0.05),orientation(B=2.236,P<0.05),root development of the supernumerary tooth(B=-2.266,P<0.05),and surgeon's years of experience(B=-2.849,P<0.05)were significantly associated with operative time.A regression equation was established:T=24.667+1.175A-5.417B+2.236C-2.266D-2.849E(T:operative time;A:age;B:vertical position;C:orientation;D:root development;E:surgeon's experience).Conclusion:The operative time for the removal of a single impacted supernumerary tooth in the maxillary incisor region is closely related to patient age,the tooth's vertical position,orientation,root development,and the surgeon's experience.The regression equation established in this study may serve as a quantitative reference for pre-operative difficulty assessment and clinician-patient communication.关键词
