This study was undertaken to investigate the changing patterns and the factors affecting hypersensitivity after the surgical periodontal treatment. For this study, 19 patients with periodontal disease were selected from the patients who visited Kyung Hee Medical Center, and they were operated by gingivectomy, Modified Widrnann flap and osseous surgery. And Pearson correlation method was used to ascertain significant correlation with some factors to root hypersensitivity. The results were as follows 1. The exposed root surfaces were significantly increased in the incidence and degree of hypersensitivity at 1 week after periodontal operation. And most of postoperative sensitivity had been naturally desensitized after the elapse of eight weeks. 2. The teeth of the young aged group showed a higher incidence and degree of preoperative and postoperative hypersensitivity than the old aged group. And postoperative hypersensitivity is more mproved in the teeth of old aged group at 8 weeks after periodontal operation. 3. The stimulus of scratch to teeth, compared to the compressed air blast and cold water, were displayed the lowest sensitivity in incidence and degree during observation peiod. The method of cold stimulus to teeth might be more reliable during the evaluation of improved hypersensitivity. 4. The correlationship between the degree of sensitivity and the width of exposed root surface was recognized before periodontal operation, but at 8 weeks after the periodontal operation there was no correlationship. 5. The correlationship between the degree of sensitivity and the plaque index of the periodontally operated teeth was recognized at 3 weeks after operation, but there was no correlationship during other observation period. 6. The correlationship between the degree of sensitivity and the sulcus bleeding index of the periodontally operated teeth was not recognized before operation, but at 8 weeks after operation there was correlationship.
