Abstract: Objective: To investigate the occurrence of dental developmental anomalies in children aged 3-12 in Wuhan. Methods: Children aged 3-12 who came to Wuhan First Stomatological Hospital from February 2021 to February 2022 were selected, and 2848 panoramic radiographs were finally included to record the dental developmental anomalies. Results: The prevalence rate of dental developmental anomalies was 11.20%, and there was no significant gender difference (P>0.05). Congenitally absent teeth was common (7.20%), especially in females (P<0.05), and mostly occurred in the mandibular anterior teeth. The prevalence of absent deciduous teeth accompanied with the absent inherited permanent teeth germ was 97.06%. Supernumerary teeth (4.00%) was considerably common in males (P<0.05), and occurred most frequently in the maxillary anterior region. Odontoma was rare (0.07%). The prevalence rate of fused teeth was 1.23%, including 25 cases of deciduous teeth fusion, all of which were the fusion of mandibular deciduous incisors and deciduous canines. The prevalence rate of deciduous tooth fusion with the absent inherited permanent teeth germ was 92.00%, which was common on one side. Conclusion: The prevalence of dental developmental anomalies in children is high, and early panoramic radiograph is important.
