Abstract:
Objective To evaluate the preliminary clinical effect of mineral trioxide aggragate (MTA) pulpotomy on immature permanent teeth with irreversible pulpitis.Methods Twenty-six immature permanent teeth with irreversible pulpitis were recuited from Department of Pediatric Dentistry, Peking University School and Hospital of Stomatology.These teeth were treated with partial or full pulpotomy according to the condition of pulp bleeding.MTA was used as pulp capping material.Patients were recalled periodically after the treatment.Clinical and radiographic effects were evaluated.Results At one year follow-up, 20 teeth were evaluated as healed or healing, 2 teeth were evaluated as failure and 4 teeth were dropped out.The success rate was considered 91％(20/22).A dentinal bridge was radiographcally observed underneath the pulpotomy site in 13 teeth(65％, 13/20).Conclusions MTA pulpotomy is an effective method for the treatment of immature permanent teeth with irreversible pulpitis.But further research with longer follow up period is required.
