[Use of dental prostheses and their relationship with oral lesions].

Objective To show the relationship between dental prostheses and the incidence and type of oral lesions developed in the Seridó region of Brazil. Methods 77 patients were registered. All were over 21 years of age, of both sexes, non-alcoholic and / or chronic smokers, and residents of the municipalities of the region corresponding to Seridó. They also all had some type of oral lesion and had been admitted to dental clinics of the University of Rio Grande do Norte. Here, the relationship between these lesions and the dental prostheses that they used was observed. Results The majority of dental prostheses related to oral lesions had more than 5 years of use and required changing. Candidiasis (45.5 %) and inflammatory fibrous hyperplasia (27.2 %) were the lesions most related to the dental prostheses. Conclusions Complete prostheses and removable partial dentures correlated with oral lesions. However, the complete prostheses had a higher percentage ready for change-out and had more than 05 years of use. This demonstrates that removable partial dentures, even without the need for exchange, showed a high correlation with the oral lesions.
