title: [Clinical investigation of pulpotomy with Pulpdent Multi-Cal in young permanent anterior teeth].
abstract: 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).
  
  
  CONCLUSIONS
  PMC is an acceptable material when used in  pulpotomy of young permanent teeth.
