Endodontic treatment of a case of fused immature central incisor with a supernumerary tooth with dens in dente is described. Although a chronic dentoalveolar abscess was diagnosed, vitality test signs were positive. Treatment consisted of pulpotomy with calcium hydroxide paste; after 2 1/2 months a permanent root canal filling was placed in the amputated part. Follow-up 2 years postoperatively indicated that the tooth has maintained its vitality. The periapical area is completely healed, and apical closure is evident.
