Abstract

Oral infections caused by Candida species are becoming more common, which may be related to an increase in the number of immunologically compromised patients as well as favorable conditions in the oral cavity that often include removable prosthetic appliances. The purpose of this study was to determine the presence of a particular Candida species in patients with PMMA and Cr-Co prosthetic appliances, as well as the salivary flow rate, and oral signs and symptoms. This investigation included a total of 120 subjects with different kinds of removable dentures. A sample of concentrated oral rinse was collected from all subjects in order to detect Candida colonization and identify the Candida species, a quantum of salivation was measured, and subjects were examined clinically. Candida spp. was predominant among the subjects who were denture wearers (p < 0.0001). In all subjects, the most frequently detected species was C.albicans. A statistically significant difference was found between the prevalence of C.albicans (p < 0.001) and C.krusei (p < 0.001) in denture wearers. Subjects with PMMA-based removable prosthetic appliances mostly demonstrated a significant decrease in salivation (p < 0.001), an increase in burning sensations (p < 0.001), and dry mouth (p < 0.001) compared to the subjects who wore partial dentures with Co–Cr metallic frameworks. Red oral lesions were more frequently found among the subjects with partial dentures with Co–Cr metallic frameworks (p < 0.001). Regardless of the material used for the denture, patients must be regularly checked by their dentists in order to prevent the development of oral lesions.

Highlights

Introduction published maps and institutional affilCandida species (Candida spp.) are one of the normal constituents of the physiological oral microbiota and may be found in 30–80% of healthy individuals [1,2,3]
The purpose of this study was to determine the colonization of Candida spp. in patients with polymethyl methacrylate (PMMA) and Cr–Co prosthetic appliances, as well as the salivary flow rate, and oral signs and symptoms
It was demonstrated that 93.8% of subjects with prosthetic appliances were positive for Candida spp. compared to 65% of the subjects who did not wear any appliance

Summary

Introduction

Introduction published maps and institutional affilCandida species (Candida spp.) are one of the normal constituents of the physiological oral microbiota and may be found in 30–80% of healthy individuals [1,2,3]. The positive finding of Candida in the oral cavity does not represent a pathological finding per se, this fungus has all the characteristics of the oportunistic pathogen, meaning it may cause an infection in the mouth when conditions arise. Candida may cause various forms of infections, from superficial to systemic conditions, which in extreme cases may lead to death [5]. The occurence of infection is influenced by factors altering the local oral environment as well as mucosal resistance. These include changes in the host’s immune system, administration of antibiotics, diabetes, smoking, advanced age, pregnancy, hyposalivation, inadequate oral hygiene, and various types of dentures [6,7,8,9].
