It is important to clarifv the relationship between prosthetic appliances and periodontal tissues for ideal prosthetic restorations. And therefore objective methods which give proper diagnosis for the first stage of gingivitis are indispensable, The purpose of this study was to investigate, using Periomicroscope, alterations of the blood vessels beneath the oral sulcular epithelium during a human experimental gingivitis, and to establish relationship between observation by Periomicrpscope and clinical and histologic findings on the first stage of gingivitis. The subjects were 22 student volunteers ages 20〜29 years with clinically normal periodontal tissues. At upper anterior teeth, gingivitis was produced by withdrawing tooth brushing for 21 days. After 21 days clinically nearly moderate gingivitis and histopathologically nearly moderatechronic gingivitis were observed, while significant differences were obtained in the changingof the capillary loop form. From the results obtained by Periomicroscope, it was suggested that the continual observation by Periomicroscope was effective for the diaznosis of gingivitis.
