Oral hygiene habits, denture cleanliness, presence of yeasts and stomatitis in elderly people

Abstract

The purpose of this study was to determine oral hygiene habits, denture cleanliness, presence of yeasts and denture stomatitis in elderly people. Seventy complete denture wearers were investigated clinically and mycologically. Subjects were evaluated according to, presence of denture stomatitis, presence of yeasts, denture cleanliness, frequency of denture brushing and denture cleaning methods. Swabs were taken from the palate investigated mycologically in order to identify the yeast colonies. No statistical relationship was found between denture stomatitis and frequency of denture brushing and denture cleaning methods. However, there was a statistically significant relationship between denture stomatitis, yeasts' presence and denture cleanliness.

Comparative effects of denture cleansers on physical properties of polyamide and polymethyl methacrylate base polymers

“…Denture cleansers are used to provide adequate denture plaque control, prevent halitosis, remove discoloring caused by foods and drinks, eliminate Candida albicans and Candida glabrata and other microorganisms, to dissolve calculus and prevent denture-induced stomatitis [3][4][5] . In patients, particularly those who are very old, have Alzheimer's disease, dementia or low motor capacity, the use of chemical agents may be the only means of denture hygiene 6,7) . Denture cleansers can be classified according to their chemical composition: enzymes, alkaline hypocholorites, neutral peroxide with enzymes, acids, disinfectants, and alkaline peroxides 7) .…”

Effect of sodium bicarbonate on Candida albicans adherence to thermally activated acrylic resin

“…[9][10][11][12] However, simple attitudes such as the removal of the denture during the night and its correct hygiene with the daily usage of disinfecting solutions are mentioned in the literature as effective in the prevention and treatment of denture stomatitis. 4,[13][14][15] Thus, many studies have been performed with the objective of evaluating the efficiency of different disinfecting solutions in the control of Candida genus yeasts, searching for a disinfecting solution that would present excellent antimicrobial activity without harming the patient's health or causing alterations in the physical-structural characteristics of dentures. [16][17][18][19][20] Within this context, the objective of the present study was to evaluate the effect of sodium bicarbonate in the adherence of Candida albicans to thermally activated acrylic resin, comparing it to other disinfecting solutions already mentioned and tested in the literature.…”

Effect of repeated cycles of chemical disinfection in microhardness of acrylic resins of complete denture base

“…The increase in health expectancy of people was followed by an increased interest in dental treatment on the part of elderly patients who were concerned not only with aesthetics but also with oral health [2][3] . However, many elderly subjects are affected by diseases that limit their manual ability [3][4] , thus requiring complementation of the mechanical cleaning with chemical substances in order to avoid the accumulation of dental microbial plaque on the oral mucosa membrane and on the surfaces of dentures, what may lead to the development of several diseases, such as candidiasis [5][6] .…”
