Clinical and Mycological Trial in Patients with Denture Stomatitis

Abstract

SUMMARY Objective: To carry out a clinical and mycological trial with patients affected by Denture Stomatitis (DS) to identify the local risk factors. Materials and Methods: 94 clinical exams were carried out on patients who used a mucosa-supported prosthesis. For the patients whose diagnosis for DS was positive, one sample of biological material both from the palatine mucosa and from the prosthesis’ base were collected to diagnose candidosis. The patients were classified according to Newton (1962) and interviewed for local risk factors. Results: Among the total of patients evaluated, 34 presented DS clinically, among which 78,6% were women, 39,3% were more that 60 years old, 60,7% used a prosthesis up to 5 years old, 82,1% used the prosthesis overnight, 92,8% presented poor hygiene conditions and 78,6% were classified as Type II according to Newton. Mycological infection was found in 100% of the prosthesis’ samples. In 71,5% of the cases, the palatine samples grew, being 40% of them an infection. The sorts identified were C. albicans (92,8%), C. parapsilosis (3,6%) and C. tropicalis (3,6%). Conclusion: Most patients with DS were women, more than 60 years old, used prosthesis up to 5 years old, used their dentures overnight and presented poor hygiene conditions. The Candida spp. infection was higher in patients with DS, being predominantly located on the prosthesis’ internal surface. C. albicans was the most prevalent microorganism.
