Abstract

Purpose

This study assessed the prevalence of maxillofacial lesions in children, i.e., 0–9 years, and adolescents, i.e., 10–19 years, in a Brazilian Oral Pathology Service and compared results with available literature.

Methods

Clinical and histopathological records from January 2007 to August 2020 were analysed and a literature review investigating maxillofacial lesions in paediatric populations was also performed.

Results

Overall, “reactive salivary gland lesions” and “reactive connective tissue lesions” were the most prevalent group of soft tissue lesions, affecting children and adolescents equally. From these, mucocele and pyogenic granuloma were the most prevalent histological diagnoses, respectively, regardless of age. These findings were consistent with the 32 studies included. Considering intraosseous lesions, “odontogenic cysts” and “periapical inflammatory lesions” were the most prevalent groups, with no relevant differences between age groups, except for the odontogenic keratocyst, which was more prevalent in adolescents. Moreover, several odontogenic tumours, such as ameloblastic fibroma and odontogenic myxoma, were significantly more prevalent in children.

Conclusion

Most maxillofacial lesions presented a similar prevalence between children and adolescents. Reactive salivary gland lesions and reactive connective tissue lesions were the prevailing diagnostic categories, regardless of age. Some odontogenic tumours and the odontogenic keratocyst showed significantly different frequencies across these age groups.
