Epidemiological, Clinical, Radiographic Characterization Of 1093 Non-Syndromic Supernumerary Teeth

This study described the epidemiological, clinical, and radiological characteristics of non-syndromic supernumerary teeth (ST) using cone beam computed tomography (CBCT), and to provide references for the clinical management of ST. Clinical (age, gender, and chief complaint of the patients ) and CBCT data (number, location, morphology, orientation, crown position, eruption status, and complications of the ST) from 782 patients (1093 ST) were collected for analysis. The male-to-female ratio was 2.30:1. ST were predominantly single (64.19%). Of the 1093 ST, 89.30% were located in the central incisor region of maxilla. Most ST were conical, inverted, impacted, positioned on the palatal side, and had completed root development. 57.82% of the ST caused complications. 53.45% of patients discovered ST by taking X-ray. There were significant differences in chief complaints across different age groups (P < 0.05). Additionally, significant differences were found in the morphology, location, orientation, and root development, depending on their eruption statuses (P <0.05). Different complications were associated with significant variations in morphology, location, orientation, and root development (P < 0.05). Furthermore, significant differences were observed in the location, morphology, orientation, and eruption status across different regions (P < 0.05). Lastly, there were significant differences in the complications among different age groups (P < 0.05). This study provides a reference for clinical management of ST in children, highlighting early screening, precise diagnosis, and personalized treatment. Our findings provide a comprehensive understanding of characteristics of ST, offering new insights for clinical management.
