The objective of this study was to determine the frequency of dental anomalies in form, size, and number in patients aged 4 to 13 years treated at a reference radiological center in 2016. The following materials and methods were used: Permission was obtained from the Radiological Center of Stomatological Images to access panoramic radiographs of patients who visited between January and June 2016. The anomalies in form, size, number, gender, and dental piece were evaluated. Results: The prevalence of dental anomalies in the studied population was 29.8%. Of these, 8.6% were anomalies in form. Fusion was the most prevalent (3.8%), with lateral incisors and canines being the most affected teeth. Additionally, 13.4% of the cases had anomalies in number, with agenesis being the most prevalent (8.6%), mostly affecting the upper second premolar. Finally, 7.7% had anomalies in size, where macrodontia was the most common (5.7%), and the most affected teeth were the lower lateral incisors. According to sex, fusion was more frequent (1.9%) in both males and females for form anomalies. For size anomalies, macrodontia had a higher frequency (4.8%) in males, and for number anomalies, agenesis had a higher frequency (6.7%) in females. Conclusion: In the studied sample of 104 radiographs, the most prevalent anomalies were those related to number, with agenesis being the most frequent (8.6%), predominantly affecting the upper second premolars. The least prevalent anomaly was peg-shaped tooth (0.96%).
