Comparison of two cleansing pastes for the removal of biofilm from dentures and palatal lesions in patients with atrophic chronic candidiasis

Abstract

The efficacy of 2 oral hygiene products, an experimental toothpaste specific for complete denture cleansing and a regular standard toothpaste, was compared in terms of denture biofilm removal and cure of palatal lesions in patients with atrophic chronic candidiasis. The degree of correlation between presence of biofilm and mucosa erythema was also evaluated. Twenty-four complete denture wearers (45-80 years old) were divided into 2 groups: experimental paste and standard toothpaste (Sorriso-Kolynos, Brazil). Both groups received soft toothbrushes. The internal surfaces of upper dentures were stained using 1% sodium fluorescein and photographed at a 45 masculine angle at 0, 15, 30 and 60 days. The slides were scanned and the areas of interest (denture total area and biofilm area) were measured (Image Tool software). The degree of erythema was evaluated on slides according to the Prosthesis Tissue Index. There was a significant reduction (1%) in the degree of biofilm (ANOVA/Tukey) between the two initial visits (0 and 15 days) and the two final visits (30 and 60 days), and in the average erythema scores (Kruskal-Wallis) between 0 and 60 days, in both groups. The Mann-Whitney test showed a significant difference (1%) between pastes in terms of biofilm degree, but no difference was found for the erythema score. Correlation values between biofilm and erythema degree were 0.3801 (experimental paste) and (0.3678 (standard toothpaste). We may therefore conclude that the experimental product was efficient for the removal of denture plaque biofilm.

Effects of mechanical and chemical methods on denture biofilm accumulation

“…Therefore, it should be stated that longer bristles are critical for denture cleansing (27, 28). The effectiveness of soft bristles in brushes for denture hygiene has also been described (18, 27–29). Although the other mechanical and combination methods provided intermediate outcomes, a trend for an additive effect provided by both toothbrushes and soaking can be inferred.…”

Antifungal activity of components used for decontamination of dental prostheses on the growth of Candida albicans

“…for acrylic resin, to which it will adhere and colonize 3,4 . Effective oral and prosthesis hygiene is therefore essential for the maintenance of tissue viability and prevention of denture associated infections 5,6 . Topical antifungal medications, such as Nystatin and Myconazol, are recommended for the treatment of oral candidiasis, especially when associated with the use of dentures 5,7 .…”

Palatal Health of Those Wearing Complete Dentures: For How Long Must a Tissue Conditioner and Chlorhexidine Gluconate Mouthrinse be Used?

“…Denture stomatitis is a term used to describe certain pathologic changes found in the oral mucosa, and two-thirds of the elderly population wearing complete dentures have problems with their palatal and gingival mucosae (1)(2)(3)(4)(5)(6)(7)(8)(9)(10). It usually affects the hard palate and occasionally causes angular cheilitis (2,6,11).…”
