Interrelationship between Candida Colonization, Dentures, and Mucosal Tissue Inflammation in the Pathogenesis of...

Despite being common, the pathogenesis of denture stomatitis (DS) is poorly known; thus, this study was conducted to examine the relationship between candida, dentures, and mucosal tissue inflammation. One hundred and twenty edentulous patients wearing a denture with clinical signs and symptoms of DS and 30 patients without DS as healthy were involved in the study. Patients with DS were divided into three groups according to Newton's classification and fungal colonies, and denture fit was assessed. No significant difference was observed between age, sex, and denture fit between the two groups (P > 0.05). The fungal colonies in patients with DS were significantly more than the controls. The majority of the patients with good denture fit had degree 1 (localized mucosal inflammation), while the majority of the patients with fair denture fit had degree 2 (diffuse inflammation on the denture bearing area) and the majority with poor denture fit had degree 3 (granular type) (P < 0.001). The fungal colonies were negative for the majority of degree 1 patients (57.1%), while they were positive for the majority of patients with degree 2 (61.3%) and degree 3 (63.2%) inflammation (P = 0.003). We concluded that the pathogenesis of DS is elusive. Multiple factors, including lack of hygiene, reduced salivary flow, poor denture care, and fit, provide an easy pathway for Candida strains to colonize dentures.
