title: A prospective clinical study of mineral trioxide aggregate for partial pulpotomy in cariously exposed permanent teeth.
abstract: The aim of this study was to evaluate the success of using gray mineral trioxide aggregate (MTA) for partial pulpotomy in cariously exposed young permanent first molars. Thirty-one first permanent molars of 23 patients with a carious exposure were treated using a partial pulpotomy technique. The age of the patients ranged from 7.2 to 13.1 yr with an average of 10 yr. Clinical and radiographic examination revealed a pulpal response within normal limits and normal appearance of the periradicular area respectively. A diagnosis of reversible pulpitis and normal periapex was established. After isolation, caries removal and carious exposure, the exposed pulp tissue was removed with a diamond bur to a depth of 2 to 4 mm. After hemostasis, 2 to 4 mm of gray MTA paste was placed against the fresh wound. The floor of the cavity was covered with a base of glass ionomer. The teeth were restored with amalgam or stainless steel crowns. Teeth were reviewed radiographically and clinically at 3, 6, 12, and 24 month intervals. Twenty-two of the treated teeth did not show any clinical or radiographic signs of failure during the follow-up evaluation period. Six teeth did not respond to vitality testing at the final follow-up period; however, no radiographic signs of failure or clinical symptoms were detected. Gray MTA was a suitable dressing agent for parital pulpotomy in cariously exposed young permanent first molars.
