title: [Observation of osteoclasts on the root surface during human deciduous teeth resorption].
abstract: OBJECTIVE
  To observe osteoclasts on the resorbing surface of human deciduous teeth.
  
  
  METHODS
  After fixing the collected deciduous teeth, we prepared the tooth slices without decalcification, treated them with HE and TRAP dyestuff, and observed the osteoclasts under light and scanning electron microscope.
  
  
  RESULTS
  There were large quantity of various forms of overlapping and huge osteoclasts with many nuclei and silk-like protuberances on the resorbing surface of deciduous teeth. The multinucleated osteoclasts align on the surface of coarse dentin.
  
  
  CONCLUSIONS
  On the resorbing surface of human deciduous teeth there are large amount of osteoclasts which can be used as a source of studying human osteoclast.
