Children and adolescents assisted in a referral oral medicine diagnostic service: 20 years of experience in Brazil.

Abstract

Background: Several lesions can affect the oral and maxillofacial region, with trends influenced by lifestyle and age.

Aim: To investigate the occurrence of oral and maxillofacial lesions in paediatric patients assisted in an oral medicine diagnostic service in Brazil over 20 years.

Design: A retrospective cross-sectional study was performed in an oral medicine diagnostic service (1999-2019). Data included sex, age, anatomic site, and diagnosis from clinical records of children (0-9 years) and adolescents (10-19 years). Lesions were diagnosed through clinical examination. Biopsy and histopathologic examination were performed when necessary.

Results: Among 10 530 records, 702 (6.67%) were from patients aged 0-19 years diagnosed with oral or maxillofacial lesions. A high frequency of females was observed (58.1%). Reactive/inflammatory lesions were the most common group of lesions (45.2%), followed by abnormalities of teeth/developmental defects (17.8%) and pulpal and periapical diseases (8.5%). Mucocele/ranula was the most common lesion in children (29.3%) and adolescents (25.3%). Lips were the most affected anatomic sites.

Conclusion: Most lesions were benign, and mucocele/ranula was the most frequent. Our results did not differ from those of histopathological-based studies, but they provided information on the occurrence of oral and maxillofacial lesions to dentists and paediatricians.
