title: Histologic evaluation of human pulp response to total etch and self etch adhesive systems.
abstract: BACKGROUND
  To investigate pulp response to the application of two types adhesive systems (total-etch and self-etch) in human premolar teeth.
  
  
  METHODS
  Cavities limited to enamel walls in all margins with 2.5 mm depth were prepared on buccal surfaces of thirty three human premolars. The cavities were treated with the following adhesive. Single Bond (SB) and Prompt L-Pop (PLP). The teeth were extracted after 30 days and prepared due to histological technique.
  
  
  RESULTS
  Pulp responses were evaluated in three field including inflammatory cell response, pulp tissue disorganization and restorative dentin formation. There were no differences in histological response of the pulp tissue (P > 0.05).
  
  
  CONCLUSIONS
  Both adhesive systems showed good biological compatibility.
