RESUMO
To determine the frequency of oral lesions related to gender, age, the length of time of denture usage, the balance of denture and cleaning methods. 106 patients who had old complete dentures and came to Dental Department to have new complete dentures were registered in the study. Frequency in relation to different factors was estimated. Cleaning methods and frequency were divided into 3 subgroups respectively as tooth brush and tooth paste/soap, denture cleansing tablets and sodium carbonate and 3 times a day, every day, every 3 days and once a week. Distributions of oral lesions in different areas were noted. The data obtained were evaluated by one-way ANOVA u test, student t test. The level of statistical significance was set at p<0.05. In 106 patients [51 men and 55 women], 37-80 years of age with a mean age of 60.28 years, oral lesions were present more as the age increases, the more lesions were observed In female patients and associated with unstable dentures. The patients displayed statistically significant difference in presence of oral lesions with the method of cleaning and the way the patients used their dentures. The complete denture wearers should be educated about the importance of periodic examination due to changes of supporting tissues and early detection of mucosal lesions to maintain their oral and denture hygiene in optimum level
