Research Abstract	To determine the relationship between dentin hypprsensitivity and gingival recession, 70 subjects (358 teeth) were examined in Tokushima University Hospital and Fukumoto Dental Clinic. The result showed that cold stimulus index per subject (y) was positively con-elated with the mean levels of gingival recession (x), indicating y=0.188x+0.194. When the teeth were individually analysed, the teeth with gingival recession showed a higher response against cold stimulation compared with those without gingival recession. In addition, the greater level of gingival recession, the higher response was observed. These findings suggest that onset and intensity of dentin hypersensitivity may be associated with the levels of gingival recession.
