Introduction And Aims:
This study investigated the epidemiological, clinical and radiologic characteristics of non-syndromic supernumerary teeth (ST) using cone beam computed tomography (CBCT) and provided references for the clinical management of ST.
Methods:
Clinical and CBCT image data from 782 patients (1093 ST) were collected. The age, sex and chief complaint of the patients, as well as the number, location, morphology, orientation, crown position, eruption status and complications of the ST, were recorded for analysis.
Results:
The male-to-female ratio was 2.30:1. A single supernumerary tooth was observed in most cases (64.2%) and located in the maxillary central incisor region (89.3%). Most ST were conical, inverted, unerupted, palatally positioned and had complete root development. A total of 57.82% of the ST caused complications. About 53.45% of patients discovered ST by taking X-ray. Chief complaints varied significantly by age group (P < .05). Morphology, location, orientation, crown position and root development varied significantly by eruption status and complication type (P < .05). Location, morphology, orientation, crown position and eruption status varied significantly by region (P < .05). Significant differences in complications were noted among the different age groups (P < .05).
Conclusion:
This study provides a reference for the clinical management of non-syndromic ST in children, emphasising the importance of early screening, precise diagnosis (particularly with CBCT) and personalised treatment. Clinicians should adopt comprehensive, stratified intervention strategies to optimise outcomes and reduce healthcare costs.
Clinical Significance:
Our findings provide a comprehensive understanding of the characteristics of ST in children, offering new insights for clinical management.
