Objective. To determine the prevalence of mandibular asymmetries in the condyle, ramus and total ramus height in patients aged 7–25 years treated at the Orthodontics service of the Dental Clinics of Universidad Santo Tomás, Bucaramanga, 2024–2025. Materials and methods. Descriptive cross-sectional study. One hundred and fifty digital panoramic radiographs were analyzed using the Thilander method. Asymmetry was defined as a difference >2 mm between sides. Data were processed in Stata 16.0 with descriptive analysis and Chi-square and Fisher’s exact tests (p<0.05). Results. Total ramus height (Co-Go) was the most affected dimension (37.33%), followed by ramus height (Inc-Go, 29.33%) and condylar height (Co-Inc, 28.67%). Mild asymmetry predominated. A significant association was found between gender and ramus height asymmetry (p=0.020). No association with age was observed. Conclusion. There is a moderate prevalence of mandibular asymmetries in this population. The Thilander analysis on panoramic radiographs is useful for initial screening.
