摘要
Abstract
Objective This study aimed to investigate the incidence,imaging characteristics,and clinical manifesta-tions 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 Decem-ber 2023.A total of 31 331 subjects were included for the radiographic assessment of the tooth eruption failure of decidu-ous 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％(296/31 331).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 mandibu-lar 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 an-tagonist(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 decid-uous molar.For deciduous molars with severe eruption failure,early intervention is crucial to mitigate complications such as malocclusion and space loss.关键词
