| description | Objectives: Understanding the prevalence of dental anomalies is crucial for improving diagnosis
and treatment by dentists. Additionally, documenting these anomalies is vital in Legal Medicine,
where dental records are instrumental in forensic investigations. Tooth number anomalies, such
as agenesis and supernumerary teeth, significantly impact a child's oral health and development. This study aimed to determine the prevalence of tooth number anomalies in a pediatric
population and highlight the significance of detecting and documenting such anomalies.
Methods: Tooth number anomalies were identified in a pediatric population (6–18 years old)
attending the Pedagogical Dental Clinics of the Faculty of Health Sciences of Fernando Pessoa University, through panoramic radiographs. Statistical analysis was conducted using
IBM© SPSS© Statistics version 25.0.
Results: Analysis of 147 panoramic radiographs revealed that 10.8% exhibited tooth number
anomalies, with 8.8% presenting agenesis and 2.0% supernumerary teeth. The mandibular
second premolar was the most frequently affected by agenesis, followed by the maxillary
second premolar. Three cases of supernumerary teeth were identified: two in the maxilla
and one in the mandible, all within the midline area.
Conclusions: Agenesis was the most prevalent tooth number anomaly in this study. No significant correlation was found between sex and tooth number anomalies identified. Though
infrequent, detecting and documenting these anomalies hold immense significance within
the patient's clinical history, serving as a crucial asset for future identification endeavors. |
