This report describes a rare case of hypoplastic primary incisor in which the pulp was exposed at the crown portion and covered by the gingiva in a 1-year-11-month-old boy. The patient was referred to us due to swelling of his labial cervical gingiva of the maxillary right primary central incisor, and on examination, extended to the hypoplastic labial surface. Radiographically, there was a round radiolucent area on the crown including the edge. Surgical removal of the swollen gingiva revealed a large defect of the labial aspect of the incisor, showing pulpal tissue inside. The tooth was treated by vital pulpotomy. Histopathologically, the removed gingival tissue contained many pieces of dysplastic tooth elements in the lamina propria portion which should have been connected to the exposed pulp. The findings suggested that pulp exposure resulted from focal dental hypoplasia not from resorption of the tooth. [ABSTRACT FROM AUTHOR] |
