摘要
目的基于口腔曲面体层片,分析乳磨牙萌出障碍的发生率、影像学特点及临床伴随症状,为乳磨牙萌出障碍的诊疗提供依据。方法回顾2021年1月—2023年12月间在浙江大学医学院附属口腔医院拍摄的4~8岁儿童口腔曲面体层片,纳入研究对象31331例,进行乳磨牙萌出障碍影像学诊断,分析记录乳磨牙萌出障碍的发生率、影像学特征及伴随症状。采用SPSS 26.0软件进行统计分析。结果本研究中4~8岁儿童的乳磨牙萌出障碍发生率为0.94%(296/31331),女性发生率是男性的1.55倍,男、女性发生率间差异有统计学意义(P<0.001)。受累牙中下颌第一乳磨牙占76.4%,下颌第二乳磨牙占13.8%,上颌乳磨牙共占9.8%。受累乳磨牙的低位咬合程度与邻牙倾斜、对颌牙伸长均有显著相关性(P<0.001)。结论基于本研究得出4~8岁儿童乳磨牙萌出障碍发生率为0.94%,女性发生率高于男性,最好发的部位是下颌,最好发的牙位是下颌第一乳磨牙。对于重度萌出障碍乳磨牙应尽早干预,以有效防止咬合紊乱、间隙丧失等并发症的出现。
Objective This study aimed to investigate the incidence,imaging characteristics,and clinical manifestations of the eruption failure of deciduous molars using panoramic radiographs to provide a foundation for diagnosis and treatment in this population.Methods This study retrospectively reviewed panoramic radiographs of children aged 4−8 years obtained from Stomatology Hospital,Zhejiang University School of Medicine between January 2021 and December 2023.A total of 31331 subjects were included for the radiographic assessment of the tooth eruption failure of deciduous molars.Incidence,radiographic characteristics,and associated complications were documented.Statistical analysis was performed using SPSS 26.0.Results The incidence of the eruption failure of deciduous molars among children aged 4−8 years was 0.94%(296/31331).The rate was 1.55 times higher in females than in males,demonstrating a significant gender difference(P<0.001).Among the affected deciduous molars,mandibular first deciduous molars accounted for 76.4%,followed by the mandibular second deciduous molars(13.8%),and the maxillary deciduous molars collectively comprised 9.8%.The severity of eruption disorders was significantly associated with the mesial and distal tilting of adjacent teeth and elongation of the antagonist(P<0.001).Conclusion The incidence of the eruption failure of deciduous molars in children aged 4−8 years was 0.94%,with a high prevalence in females and a predilection for the mandible,particularly the mandibular first deciduous molar.For deciduous molars with severe eruption failure,early intervention is crucial to mitigate complications such as malocclusion and space loss.
