Resumo


Objective: The present study aims to evaluate the radiographic position of the mandibular foramen in children aged between 4 and 12 years. Material and methods: The sample consisted of 505 panoramic radiographs of male (n=242) and female (n=263) Brazilian children aged from 4 to 12 years. The panoramic radiographs were obtained for treatment purposes at the Pediatric Dental Clinics of the Federal University of Paraná, Brazil. Digital analysis was performed by an experienced radiologist using Radiocef Studio® 2 (Radiomemory®, Belo Horizonte, Brazil) software. The radiographic position of the mandibular foramen was assessed measuring the distance between an x-axis, parallel to the occlusal plan, and the center of the foramen. Results: The mandibular foramen was mostly detected below the x-axis in children younger than 7 years old and above the x-axis in older children. Spearman Correlation Coefficient revealed a significant association between the measured distance and the age of the studied children (p<0.001). Conclusion: The radiographic position of the mandibular foramen varied according to age, indicating valuable applications in anesthetic pediatric dentistry.
