Abstract
ABSTRACT
Ectopic tooth eruption is an uncommon condition, with reported occurrences in areas such as the nasal septum and mandibular condyle. Teeth located within the maxillary sinus are particularly rare and may result from trauma, infection, or developmental abnormalities. These teeth are often identified incidentally in the second or third decade of life and may remain asymptomatic. Advances in cone beam computed tomography (CBCT) have enhanced diagnostic accuracy in both routine and complex dental cases due to its ability to provide three-dimensional visualization. This report presents two cases of ectopic teeth in the maxillary sinus, both detected incidentally on CBCT; one in a female patient with no history of trauma, and another in a male patient with post-traumatic displacement following a road traffic accident. Both patients were asymptomatic at the time of diagnosis. Management options, including surgical removal and conservative monitoring, are discussed, with attention to potential complications such as sinusitis and impaired drainage. These cases highlight the need for patient-specific evaluation and demonstrate the indispensable role of CBCT in accurate diagnosis, risk assessment, and informed decision-making regarding rare ectopic teeth.
