title: Indirect pulp capping in the primary dentition: a 4 year follow-up study.
abstract: OBJECTIVE
  Evaluate clinical and radiographic changes in primary teeth submitted to indirect pulp capping (IPC) over a 48-month-period.
  
  
  METHODS
  Twenty seven primary molars with deep caries, but without preoperative signs of irreversible pulpits, were treated with IPC. The teeth were randomly divided into two groups, according to the material used for protection of the dentin-pulp complex. (1) a calcium hydroxide liner (Dycal) and (2) glass ionomer cement (Vitremer).
  
  
  RESULTS
  After 48 months, Group-1 showed a success rate of 88.8% and Group-2 of 93%. No statistical significant difference between the groups was observed (P = 0.62).
  
  
  CONCLUSIONS
  The results of this study suggested that indirect pulp capping in primary teeth arrests the progression of the underlying caries, regardless of the material used as a liner.
