ABSTRACT
Complications resulting from removable denture consist of a wide range of oral mucosal lesions, the prevention of which and dealing with their complications are both the dentist's and the patient's responsibilities. The aim of this study was to evaluate the frequency of denture hyperplasia in Mashhad Dental School. In this descriptive-cross sectional study, we aimed to assess the incidence of denture hyperplasia lesions on biopsies received in the Department of Pathology of Mashhad Dental School since 1357 till 1387 Collected data were statistically analyzed using the SPSS software and tables and diagrams were generated. The lesions results from denture were 5.6% of all lesions. From 462 cases, 368 cases occurred in women and 94 in men. In 97.8% of patients IFH and in 2.2% of patients IPH were found. In this study, IFH with 452 cases were observed more frequently in the female [79.7%] than the male subjects and in the 5th and 6th decades [68.2%]. The common location of this lesion was mandible [69.9%] and anterior region [85.7%]. Lesion enlargement [4.6%], Pain and burning [9%] sensation were recognized as the two most common referring factors to the dentist associated with these lesions. In this study the IFH had the highest frequency and the IPH occurred only in a small percentage of lesions. Overall, the denture hyperplasia was more common in females in the 4th and 5th decades. The highest frequency of referring to the Dental School was between years 1367-1376 [54.9%]
