458例上切牙区多生牙的临床资料分析

Clinical data analysis of 458 cases of supernumerary teeth in the upper incisor area

目的 分析及总结上切牙区多生牙的临床特点,为其诊治提供参考。方法 收集于河北医科大学口腔医院口腔颌面外科就诊的患者458例,对其就诊年龄、性别、多生牙数目和方向、就诊原因、麻醉方式、手术时间等进行统计,并采用SPSS 21.0软件包对数据进行统计学分析。结果 458例患者,共有710颗多生牙。患者平均年龄(8.64±4.31)岁,男女比例为3.63∶1;儿童组人数最多,为387例(84.50%)。患者中,2颗多生牙者231例(50.44%),1颗多生牙者218例(47.60%)。多生牙呈倒置位最多,为362颗(50.99%);临床表现中,以无意中行影像学检查发现者最多,为153例(33.41%)。患者中,390例(85.15%)选择了全麻手术;平均手术时间(23.42±13.95) min。不同性别间的多生牙数目、方向、萌出状态,无明显差异(P>0.05);不同年龄组患者的多生牙数目无明显差异(P>0.05),不同年龄组患者的多生牙方向、萌出状态的差异均有统计学意义(P<0.05)。结论 上切牙区多生牙多见于儿童期,男性发病率明显高于女性;患者常无意中发现,以1颗和2颗者多见,主要为倒置位。

Objective This study aims to analyze and summarize the clinical characteristics of supernumerary teeth in the upper incisor area, and provide a reference for its diagnosis and treatment. Methods A total of 458 patients were collected from the Department of Oral and Maxillofacial Surgery, Hospital of Stomatology, Hebei Medical University.Herein, their age, sex, number of supernumerary teeth, direction, reasons, anesthesia methods, and operation time were statistically analyzed using the SPSS21.0 software package. Results There were 710 supernumerary teeth in 458 patients with an average age of(8.64±4.31) years, and the male-to-female ratio was 3.63:1. The number of children is the largest with 387 cases(84.50%). A total of 231 cases(50.44%) had two supernumerary teeth and 218 cases(47.60%)had one supernumerary tooth. A total of 362(50.99%) were in an inverted position. Among the clinical manifestations,153 cases(33.41%) were found by unintentional imaging examination. Meanwhile, 390 cases(85.15%) chose general anesthesia. The mean operation time was(23.42±13.95) min.There was no statistical difference observed in the number, direction, and eruption state of the supernumerary teeth between different sexes(P>0.05). There was no significant difference in the number of supernumerary teeth among different age groups(P>0.05). However,there were significant differences observed in the direction and eruption status of supernumerary teeth among different age groups(P<0.05). Conclusion The supernumerary teeth in the upper incisor area are more common in childhood,and the incidence of male teeth is higher than that of female teeth, which are often found accidentally by patients, particularly one or two teeth, mainly in an inverted position.
