Abstract
ABSTRACT Developmental disorders of human dentition may result in various abnormalities according to etiologic agents and the developmental period involved. The size, shape and number of teeth may be affected. Dental abnormalities can occur singly or in multiples in an individual and may or may not be associated with syndromes. Complementary radiographic examinations are valuable for diagnosis, especially in lesions that are asymptomatic and detected only through examination. The present study is intended to report a case of an incidental finding in panoramic radiography of an odontoma, a supernumerary tooth and permanent tooth agenesis in the same non-syndromic individual. According to the literature, the association of hypodontia and hyperdontia (called concomitant hypo-hyperdontia) is most common. The association of hyperdontia and odontoma is uncommon but still reported. However, regarding the association of hypodontia and odontoma no reports were found, as well as the association of the three pathologies.
Highlights
Odontomas are benign mixed odontogenic tumors formed by odontogenic tissues in various degrees of differentiation arranged in a disorganized way
They are still classified by the World Health Organization (WHO) as tumors, many authors consider them hamartomas instead of true neoplasm, due to their behavior being atypical of tumor lesions, as they do not evolve in size until development and do not invade adjacent tissues [1]
Hyperdontia and hypodontia are conditions that affect the number of teeth, the first being an increase in the normal number and the second a reduction
Summary
Odontomas are benign mixed odontogenic tumors formed by odontogenic tissues in various degrees of differentiation arranged in a disorganized way. Functional and aesthetic consequences are observed, such as disturbances of dental eruption and malocclusion, and these anomalies may undergo pathological transformations of the dental tissues [5,6]. They are mostly asymptomatic and, often diagnosed incidentally during routine radiological examinations. The present study aims to report a case of incidental finding in a panoramic radiography of complex odontoma, supernumerary tooth and permanent tooth agenesis in the same individual. Panoramic radiography (figure 1) presented a supplementary supernumerary tooth of 41, agenesis of 43 and persistence of 83, and a complex odontoma adjacent to the apical region of 83 was observed.
