RESUMO
The purpose of this study was to survey the frequency of denture-related lesions of the oral mucosa in patients treated at a Brazilian dental school and to determine if the oral lesions were related to age, sex, denture type, length of denture use and denture cleaning methods. The denture-related lesions observed in this study were chronic atrophic candidiasis, chronic hyperplastic candidiasis, denture-induced fibrous inflammatory hyperplasia (FIH), traumatic ulcer, angular cheilitis and flabby ridge. The most frequent lesion, chronic atrophic candidiasis, occurred more frequently in females, in complete maxillary denture wearers, with denture use for 16-20 years. The most common method of cleaning dentures was a toothbrush and toothpaste. These results suggest that dentures can cause a wide range of lesions of the oral mucosa, that could be prevented with follow-up to evaluate dentures and provide instructions on how to maintain oral tissues healthy.
