Dr. Dimple Sahni, Dr. Girish Sahni

Abstract: An ectopically erupted tooth with infected dentigerous cyst within the maxillary sinus of a child is a rare occurrence. A twelve year old male child presented with rhinorrhoea, haliotosis and swelling over the right cheek. It was diagnosed to be a large dentigerous cyst with ectopic tooth and right maxillary sinus. However it is a rare entity in children commonly occur in mandible of middle aged persons. Early diagnosis and treatment is a essential as it has greater tendency to produce some resorption of other teeth as compare to other jaw cyst. Although marsupialization is treatment of choice in children but in this case the cyst had lined the antral cavity hence enucleation had to be done through Caldwell luc approach.
