comparison for community periodontal index of treatment needs (cpitn) between insulin dependent diabetic patients and healthy individuals

abstract introduction: diabetes increase salvia sugar and change its bacterial flora these changes destroy periodon-tal tissues. there are contravercies about affect of diabetes on periodontal tissues. in this study cpitn index that show intensity of periodontal damage was compared in insulin depended with healthy individual. methods and materials: in this study 132 cpitn index measured in 132 insulin depended diabetic patients and 132 healthy individual that two groups had similar oral hygiene. thus cpitn index in diabetic patients compared with healthy individuals. results: there was no significant difference for cpitn index in male and female diabetic patients. cpitn index in diabetic patients was 1.36±1.24) and significantly higher than healthy individuals (0.54±0.77). conclusion: saliva change in diabetic patients and change in oral micro organism explins this subject. effects of diabetes in oral cavity and periodontal issue can increase cpitn index in diabetic patients. these changes were not sex related.
