title: [Root canal morphology of deciduous tooth].
abstract: OBJECTIVE
  To find out the morphological regularity of root canal in the primary tooth.
  
  
  METHODS
  Through transparent specimen of a set of deciduous teeth, the shape of root canal was observed under stereomicroscope.
  
  
  RESULTS
  Among the deciduous anterior teeth, 92% were single canal except for one single-double mixed canal. Maxillary deci-duous molar had 3 canals and mandibular deciduous molar had 4 canals, lateral canal and anastomosis between the root canals were popular in deciduous molar.
  
  
  CONCLUSIONS
  Deciduous root canal morphology is simple in anterior teeth and comparatively complex in molar.
