Furcal perforations may occur during access opening of the pulp chamber or cavity preparation. The perforation can cause an inflammatory reaction in the periodontal ligament. Management of these iatrogenic accidents can pose a significant clinical challenge, mainly when they occur in primary teeth. Current developments in the techniques and materials utilized for root perforation repair have enhanced this procedure's prognosis. Recently, mineral trioxide aggregate (MTA) has been used for several dental purposes. This biocompatible material promotes bone healing and elimination of clinical symptoms. The purpose of this case report was to describe the treatment of a furcal perforation using mineral trioxide aggregate (MTA) in a primary molar tooth. After 20 months, the tooth was asymptomatic. The radiolucent image had disappeared and bone formation at the furcation area had been observed, suggesting healing of the underlying periodontal tissues. Therefore, MTA may be considered an alternative option for the repair of furcal perforation in primary teeth, prolonging the longevity of these dental elements.

Pyogenic granuloma (PG) is a lesion characterized by non-neoplastic proliferation of endothelial cells, occurring in gingival tissue and representing an excessive reaction of the connective tissue to stimuli or injuries. The purpose of this report was to describe the treatment of an oral pyogenic granuloma, with emphasis on clinical, histopathological, and radiographic aspects. The surgical therapy comprised lesion excision followed by pedicle graft to cover the exposed root surface. The patient's pyogenic granuloma has been under control for a year, and recurrence has not been observed. The permanent teeth erupted correctly and the gingival tissue of both the receptor and donor sites shows a satisfactory clinical appearance.
