title: [A primary study of relationship between proteolytic enzymes in dental plaque and deciduous caries].
abstract: OBJECTIVE
  The purpose of this paper was to study the role of proteolytic enzymes in dental plaque in deciduous caries occurrence.
  
  
  METHODS
  Fluorometry and spectrometry were used separately to determine the activities of leucine amino peptidase, dipeptidyl peptidase IV and trypsin-like proteinase in caries-positive and caries-free children.
  
  
  RESULTS
  The activities of the three enzymes in dental plaque in different children were same (P > 0.05).
  
  
  CONCLUSIONS
  The three enzymes may be not related to deciduous caries.
