We have experienced the Epulis fissuratum in clinic. The most cases are caused by the continuous repeating mechanical stimuli due to the ill-fitting dentures.When we observed them, we have gained the following results.Especially about the dentures which brought the chronically mechanical irritation, we have measured the occlussal stress-concentration by means of “Prescale (FUJI FILM Co., Ltd)”.1. The average of the age was 61.6 S.D.±8.5 years old.2. In respect of sex, the female were 8 cases and the male was a case. The female caused more than the male.3. The position of the proliferation located the parts of the incisor and premolar. The maxilla were 6 cases and the mandible were 3 cases. The maxilla caused more than the mandible.4. About the growing form, the lobulated iype were 5 cases, the ridge type were 3 cases, and the mixed type was a case.5. About the chief complaint, there were many swelling, but few pain.6. All dentures were ill-fitting, and polished insufficiently.7. About the histologic features, we have observed the epithelial proliferation, the proliferation of the fibrous conective tissue, and the accessory salivary glands in a few cases.8. About the alveolar ridge and the dental arch, there were discrepancy between the maxilla and the mandible in the most cases. 9. About the occlusal stress-concentration, the result which used “Prescale (FUJI FILM Co., Ltd)” were distributed the press as the parts of the incisor as the molar.
