摘　　要：目的探讨下颌恒切牙先天缺失的性别差异。方法收集2017年至2020年于杭州市中医院口腔科就诊的正畸患者1262例,分别统计每年患有下颌恒切牙先天缺失、下颌恒切牙单颗及多颗牙缺失的男患者例数和和女患者例数。分析下颌切牙缺失发病的性别差异。结果2017年至2020年,杭州市中医院口腔科的正畸就诊患者中,男女性别差异无统计学意义(P>0.05)。下颌恒切牙先天缺失的患者女性明显多于男性(P<0.05)。单颗下颌恒切牙先天缺失的女性患者多于男性(P<0.05)。多颗下颌恒切牙先天缺失的患者,男女性别无差异(P>0.05)。结论下颌恒切牙先天缺失具有显著的性别差异,女性明显多于男性,且单颗下颌恒切缺失者女性较男性多见。Objective To explore the gender difference of the congenital absence of pennanent mandibular incisors.Methods Collected 1,262 orthodontic patients who attended the Department of Stomatology,Hangzhou Hospital of TCM from 2017 to 2020,and counted the number of male or female patients with congenital absence of permanent mandibular incisors,single and multiple missing teeth of permanent mandibular incisors each year.Analyze the gender differences in the incidence of mandibular incisor loss.Results From 2017 to 2020,among orthodontic patients in the Department of Stomatology,Hangzhou Hospital of TCM,there was no statistically significant difference in gender between men and women(P>0.05).There were significantly more women than men with congenital absence of permanent mandibular incisors(P<0.05).There were more female patients with a single permanent mandibular incisor missing than males(P<0.05).There was no difference between male and female in parients with congenital absence of multiple permanent mandibular incisors(P>0.05).Conclusion There is a significant gender difference in the congenital absence of mandibular permanent incisors,which is more in females than in males,the loss of single mandibular permanent incision is more common in females than in males.
