title: A comparative evaluation of ProRoot mineral trioxide aggregate and Portland cement as a pulpotomy medicament.
abstract: BACKGROUND
  Recently, some studies have compared mineral trioxide aggregate (MTA) with portland cement (PC), concluding that the principle ingredients of PC are similar to those of MTA. The purpose of the present study was to evaluate the biocompatibility of PC as a pulpotomy medicament.
  
  
  METHODS
  Thirty premolars that scheduled for extraction for therapeutic reasons were randomly assigned to two experimental groups: ProRoot MTA (PMTA) and PC. After isolation and pulp exposure, pulpotomy was carried out and pulps were dressed with PMTA and PC. After 6 months, the teeth were extracted and prepared for histological analysis based on Cox et al. criteria. The data were analyzed by Z-test of proportion with 1% of allowed error.
  
  
  RESULTS
  No statistically significant difference was found between the two groups with respect to inflammatory response, soft tissue organization, and dentine bridge formation (P > 0.05).
  
  
  CONCLUSIONS
  PC was associated with similar favorable biological response to pulpotomy treatment as PMTA. The findings of this study support the idea that PC can be considered a cheaper substitute to MTA.
