[Clinical investigation of pulpotomy with Pulpdent Multi-Cal in young permanent anterior teeth].

OBJECTIVE: To investigate the clinical characteristics and prognosis of pulpotomy with Pulpdent Multi-Cal (PMC) in young permanent incisors. METHODS: Twenty-five young permanet incisors with vital pulps and complicated crown fractures were treated by pulpotomy with PMC at the Emergency Department of Peking University School and Hospital of Stomatology. The teeth were checked clinically and radiographically during fixed intervals. Healing of the pulp was considered to have taken place if the following criteria were met: absence of clinical symptoms, absence of apical radiolucency, continued root development in immature teeth, radiographic evidence of dentin bridge formation, and positive response to pulp vitality tests. The results were compared with the teeth which underwent pulpotomy with preparation made by our hospital. RESULTS: Followed up for 6-15 months (median 12 months), on basis of the criteria for pulp healing, all teeth got successful treatment. And all the teeth showed radiographic evidence of dentin bridge formation within 1 to 3 months after pulpotomy. The operation time of PMC pulpotomy was significantly shortened (P<0.01). The root length of teeth performed with PMC pulpotomy and normal teeth had no significant difference (P>0.05). CONCLUSION: PMC is an acceptable material when used in pulpotomy of young permanent teeth.
