Evaluation of Prevalence of Soft Tissue Lesions Arising from Removable Prosthesis in Hamadan Patients 1997

There was no documented information about the subject of this survey in the country. Regarding the importance of these lesions and their pathologic changes and considering this epidemiologic survey as a base for future analytical researches , the survey seemed to be justified. A cross - sectional descriptive study was designed and with a cluster-random sampling the 350 patients selected in five zone of Hamadan, who were interviewed, and clinically examined at their homes in 3997. 78.8% of the surveyed patients had at least one denture induced soft tissue lesion. The most common lesion was inflammatory fibrous hyperpisia (26.8%)and Angular chellitis had the least prevalence(2.5%). Other soft tissue changes lied between these two rates. The denture induced soft tissue lesions had considerably more prevalence than any reports up to the time of survey which need more investigation.
