A RETROSPECTIVE STUDY OF THE CLINICAL RELATIONSHIP BETWEEN THE USE OF REMOVABLE DENTURES AND THE DEVELOPMENT OF FIBROUS PROLIFERATION IN THE ORAL MUCOSA

OBJECTIVE: To evaluate the prevalence of fibrous lesions in the oral mucosa, associated with the use of removabledentures, at the Egas Moniz University Clinic between 2016 and 2019. We evaluated 240 MATERIALS AND METHODS:clinical histories of individuals who were rehabilitated with removable dentures who consulted the department of OralRehabilitation in the University Dental Clinic of IUEM, between 2016 and 2019. Subsequently, the data was submitted to astatistical analysis in the SPSS program. RESULTS:111 (46.3%) individuals were diagnosed with a fibrous lesion and 129(53.8%) had no fibrous lesion. Regarding gender and presence of injury, both variables are dependent p <0.001. Themost common site of appearance of these lesions was the jugal mucosa, with 39.6% of cases. Age group and lesionpresence variables are independent p = 0.766 (p <0.05). As for the type of denture and presence of lesion, these aredependent p = 0.001 (p> 0.05). The most common lesion was denture- induced fibrous hiperplasia with 106 cases(95.5%) and the second lesion was pyogenic granuloma (in involutionary phase) with 5 cases (4.5%). CONCLUSION:There is a direct relationship with gender and the prevalence of oral fibrous lesions, the same was true for the type ofprosthesis the patient had. The age group did not influence the appearance of lesions
