Prevalence of Denture Stomatitis in Patients Using Denture in Sari City, Iran, in 2020-2021

Denture stomatitis is an inflammatory condition in the oral mucosa which develops under the removable denture and affects a considerable percentage of denture users. Due to insufficient studies on this issue in Iran, we investigated the prevalence of denture stomatitis in patients using dentures.

In the current descriptive-analytical cross-sectional study, 130 patients referred to the dental school clinic and other dental clinics in Sari City, Iran, were examined using the census method. Demographic information about the patients, such as age, sex, systemic problems, and type of denture stomatitis (based on Newton’s classification), were recorded. The denture was also clinically examined for its suitability in the mouth. After entering the data in SPSS, version 20, the study variables were analyzed through bivariate correlation, descriptive analysis, and frequency analysis.

A total of 130 patients using dentures (85 male, 45 female) were studied. About 26.2% (n=34) of the patients had denture stomatitis, of whom 58.8% (n=20) were type II and 41.2% (n=14) were type III. There were significant differences between denture’s age (P<0.001), patient’s age (P=0.049), denture use during the day (P=0.002), diseases (P<0.001), denture cleaning frequency (P<0.001), and duration of denture use (P<0.001). Cigarette (P=0.093) and alcohol consumption (P=0.905), and sex (P=0.349) were not significantly associated with the prevalence of denture stomatitis.

The results of the current study presented a high prevalence of denture stomatitis in patients using dentures. Also, the denture’s age, patient’s age, cleaning frequency, duration of denture use, and appropriate denture significantly affected the prevalence of denture stomatitis.
