Prevalence and possible predictors of the occurence of denture stomatitis in patients older than 60 years Prevalencija i mogući prediktori nastanka protetskog stomatitisa kod pacijenata starijih od 60 godina Abstract Background/Aim. Denture stomatitis (DS) is one of the most common oral health problems among elderly population with removable dentures. Despite the high prevalence, etiology of the disease is not completely understood. It appears to be multifactorial, with a predominance of local factors. The aim of the study was to determine the prevalence and risk factors that contribute to the development of DS in upper removable denture wearers. Methods. This clinical study comprised three groups of subjects with upper removable dentures: the DS group, and the positive and negative control groups. Swab samples were taken from the tongue and palatal mucosa for microbiological examination. Data of denture age, dentures night wearing, unstimulated salivary flow rate (US-FR) and saliva pH values were evaluated for all the participants. Results. The prevalence of DS was found to be 26.5%. Significantly higher values of overnight wearing (p = 0.000) and the mean age of dentures (p = 0.022) were found in the DS group compared to the controls. In relation to the positive mycological finding, a borderline significance difference among the groups was confirmed (p = 0.053). No significant association was found between DS and gender, age, the type of dentures, USFR, pH of saliva and bacteria findings. The patients who wore dentures at night had 26 times more chances to get DS compared to the patients who did not wear them overnight. Conclusion. This study confirms similar characteristics of DS prevalence in elderly population of Vojvodina compared to European. Continuous (overnight) wearing of dentures is considered to be major direct risk factor for DS development, while secondary role is attributed to denture age and oral Candida infection. ApstraktUvod/Cilj. Protetski stomatitis (PS) jedno je od najčešćih oboljenja usne duplje kod starijih osoba sa mobilnim protezama. Uprkos velikoj rasprostranjenosti, etiologija oboljenja nije u potpunosti razjašnjena. Ona je verovatno multifaktorijalna, sa predominacijom lokalnih faktora. Cilj rada bio je da se utvrde prevalencija i faktori rizika koji doprinose nastanku PS kod nosilaca gornjih mobilnih proteza. Metode. Studija je obuhvatila tri grupe ispitanika sa gornjim mobilnim protezama: grupu sa PS, te pozitivnu i negativnu kontrolnu grupu. Brisevi jezika i nepca uzeti su za mikrobiološko ispitivanje. Za sve ispitanike utvrđivani su podaci o starosti proteza, noćnom nošenju proteza, sijalometriji i pH vrednosti pljuvačke. Rezultati. Prevalencija PS iznosila je 26,5%. Utvrđena je statistički značajna razlika između grupe sa PS i kontrolnih grupa u odnosu na noćno nošenje proteza (p = 0,000) i prosečne starosti proteza (p = 0,022). Pozitivan mikološki nalaz u granicama statističke značajnosti (p = 0,053) utvrđen je kod pacijenata sa PS. Nije utvrđena značajna povezanost između prot...

Background:The aim of the study was to determine the microbial presence and type in the biofilms present on the surface of oral squamous cell carcinomas and benign lesions of oral mucosa.Methods: Thirty new (untreated) patients with oral squamous cell carcinoma were examined. The control group consisted of thirty subjects with benign lesions of oral mucosa. Swab samples were taken from the superficial layer of the carcinoma and benign lesions for bacteriological examination. Swabs were transported within 2 hours and immediately sown and incubated. Oral health index was assessed in all patients. Results:The prevalence of pathological bacterial microflora was significantly higher in cancer patients (p<0.01). No significant associations were found between bacterial presence and gender, localization, cigarette smoking, alcohol consumption and denture wearing (p>0.05). Poor oral hygiene was also registered in cancer patients. Conclusion:Possibility of microflora retention on irregular oral carcinoma surface possibly contributes to chronic inflammation often observed on the surface of oral carcinomas.
