Due to insufficient studies on this issue in Iran, we investigated the prevalence of denture stomatitis in patients using dentures.<br> <strong>Materials and Methods</strong>: 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&rsquo;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.<br> <strong>Results</strong>: 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&rsquo;s age (P<0.001), patient&rsquo;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.<br> <strong>Conclusion</strong>: The results of the current study presented a high prevalence of denture stomatitis in patients using dentures. Also, the denture&rsquo;s age, patient&rsquo;s age, cleaning frequency, duration of denture use, and appropriate denture significantly affected the prevalence of denture stomatitis.</span></span></span></span></div> Denture, Prevalence, Denture stomatitis 137 142 http://jhs.mazums.ac.ir/browse.php?a_code=A-10-934-1&slc_lang=en&sid=1 Atefeh Ramezani عاطفه رمضانی ramezaniatefeh2007@yahoo.com 10031947532846009769 10031947532846009769 No Department of Prosthodontics, Dental Research Center, Faculty of Dentistry, Mazandaran University of Medical Sciences, Sari, Iran. دانشگاه علوم پزشکی مازندران Melika Mollaei ملیکا ملایی melika.mollaei.7@gmail.com 10031947532846009770 10031947532846009770 No Student Research Committee, Faculty of Dentistry, Mazandaran University of Medical Sciences, Sari, Iran. دانشگاه علوم پزشکی مازندران Jamshid Yazdani Charati جمشید یزدانی چراتی jamshid_1380@yahoo.com 10031947532846009771 10031947532846009771 No Department of Epidemiology, Addiction Institute, Mazandaran University of Medical Sciences, Sari, Iran. دانشگاه علوم پزشکی مازندران Hakhamanesh Tavakolian هخامنش توکلیان mkpebfu@telegmail.com 10031947532846009772 10031947532846009772 No Student Research Committee, Faculty of Dentistry, Mazandaran University of Medical Sciences, Sari, Iran. دانشگاه علوم پزشکی مازندران Abbas Mesgarani عباس مسگرانی a_mesgarani@yahoo.com 10031947532846009773 10031947532846009773 No Department of Endodontics, Dental Research Center, Faculty of Dentistry, Mazandaran University of Medical Sciences, Sari, Iran. دانشگاه علوم پزشکی مازندران Tahereh Molania طاهره ملانیا t_molania117@yahoo.com 10031947532846009774 10031947532846009774 Yes Department of Oral Medicine, Dental Research Center, Faculty of Dentistry, Mazandaran University of Medical Sciences, Sari, Iran. دانشگاه علوم پزشکی مازندران
