Abstract: The morphologic feature of radicular dentin in sensitive and naturally desensitive area was observed with scanning electron microscopy(SEM).Eight specimens were taken from six patients with periodontal diseases,It was establtshed that the orifices of dentinal tubules in hypersensitive areas were much more than those in naturally desensitive areas. The dimension of the orifices in hypersensitive areas was much larger thanthat in naturallydesensitIve areas.The results suggest that there is relationship between dentin morphology and dentin hypersensitivity,In this article,a new dentin biopsy technique with hollow drill was reported also.
