Pulp therapy in a maxillary fused primary central incisor--report of a case.

This paper describes a case in which pulp therapy was provided in a fused maxillary primary central incisor in a 4-year-old patient with a history of fistula on the gingival mucosa. The tooth involved was larger than expected, suggesting fusion. The diagnosis of fusion was confirmed on radiographical examination. The clinical management of the case is described and the diagnosis and treatment discussed.
