摘要： 目的: 分析上切牙区两颗多生牙患者的临床特点,为临床诊治提供参考。方法: 收集2017年1月—2021年12月就诊于河北医科大学口腔医院的上切牙区两颗多生牙患者309例,对其年龄、性别、就诊原因及多生牙相关资料进行统计,并对不同性别、不同年龄组的多生牙生长方向、萌出状态、形态、发育等进行分组分析。采用SPSS 21.0软件包对数据进行统计学分析。结果: 309例患者中,平均年龄（8.21±3.89）岁,男女比3.83∶1。6~12岁组就诊人数最多,为205例（66.34%）。204例（66.02%）两颗多生牙生长方向不一致;223例（72.17%）两颗多生牙形态不一致。194例（62.78%）两颗多生牙牙根发育完全,174例（56.31%）两颗多生牙均为未萌状态。不同性别间两颗多生牙在生长方向、萌出状态、发育、就诊原因及对邻近组织影响方面无显著差异（P>0.05）,而在形态方面有显著差异（P<0.05）。不同年龄组两颗多生牙在生长方向方面无显著差异（P>0.05）,在萌出状态、形态、发育、就诊原因及对邻近组织影响方面有显著差异（P<0.05)。结论: 上切牙区两颗多生牙患者,多见于替牙期,男性多于女性,性别对多生牙的形态有一定影响,年龄对多生牙的萌出状态、形态、发育等有一定影响。

Abstract: PURPOSE: To analyze and summarize the clinical characteristics of patients with two supernumerary teeth in the upper incisor area, in order to provide reference for clinical diagnosis and treatment. METHODS: A total of 309 patients with two supernumerary teeth in the upper incisor area who were admitted to Hospital of Stomatology, Hebei Medical University from January 2017 to December 2021 were collected, their age, gender, reasons for medical treatment, and related information on supernumerary teeth were statistically analyzed. The growth direction, eruption status, morphology, and development of supernumerary teeth in different genders and age groups were grouped and analyzed. SPSS 21.0 software package was used for data analysis. RESULTS: Among 309 patients, the average age was (8.21±3.89) years old, and the male to female ratio was 3.83∶1. The 6-12 years old group had the highest number of visits, with 205 cases (66.34%); 204 cases (66.02%) had 2 supernumerary teeth with inconsistent growth directions, 223 cases (72.17%) had 2 supernumerary teeth with inconsistent morphology, 194 cases (62.78%) had 2 supernumerary teeth with fully developed roots, 174 cases (56.31%) had 2 supernumerary teeth in an unexpired state. There was no significant difference(P>0.05) in the growth direction, eruption status, development, treatment reasons, and impact on adjacent tissues between the two supernumerary teeth of different genders, but there was significant difference(P<0.05) in morphology. There was significant difference in the growth direction of two supernumerary teeth in different age groups(P>0.05), but there were significant differences in eruption status, morphology, development, medical reasons, and impact on adjacent tissues(P<0.05). CONCLUSIONS: Patients with two supernumerary teeth in the upper incisor area are mostly seen in the mixed dentition period. The incidence rate of males is significantly higher than that of females. Gender has certain impact on the morphology of supernumerary teeth, and age has certain impact on the eruption, morphology, and development of supernumerary teeth.
