RESUMO
Odontoma is the most common odontogenic tumour derived from both epithelial and mesenchymal components of the tooth-forming apparatus. It is commonly diagnosed in the second and third decades of life when a radiograph is taken for some other purpose, as most cases are asymptomatic. This case involves a young boy, with the chief complaint of pain and swelling in the lower left back region. An intraoral examination revealed a carious and hypoplastic left permanent mandibular first molar. Although the molar was suspected as the source of his symptoms, radiographic imaging revealed multiple odontomas and missing second and third molar tooth buds. This case highlights the pathological effects of odontomas on surrounding teeth, including the malformation of the first molar and aplasia of the second and third molars. The sole management depends on the early diagnosis, histopathological examination to rule out malignancy and conservative surgical excision of these tissues.
