Effervescent tablets and ultrasonic devices against Candida and mutans streptococci in denture biofilm

Abstract

The effervescent tablets significantly reduced mutans streptococci and total aerobes from denture biofilm. However, they was not as effective against C. albicans. Ultrasonic cleansing presented a discrete antimicrobial effect and was less effective than the tablets for complete denture disinfection.

Color Stability, Surface Roughness and Flexural Strength of an Acrylic Resin Submitted to Simulated Overnight Immersion in Denture Cleansers

“…Several agents are indicated for denture biofilm removal, classified into mechanical and chemical agents (1). Cleaning by chemical method consists in immersing the denture in solutions with solvent, detergent, antibacterial and antifungal actions, and such solutions can be employed alone or in association with brushing or ultrasonic devices (2,3). There are two main classes of immersion denture cleansers: NaOCl and alkaline peroxides (4).…”

Effect of Alkaline Peroxide-type Denture Cleaners to the Microbial Profile in Maxillary Complete Denture

“…Previous studies have shown that denture cleansers are effective only against polymicrobials, but are not effective against Candida species, which coincides with the result of this study. 3,14,15 The different response achieved for different microorganisms may be due to the location of the microorganism itself. Polymicrobials may be located in more superficial layers of the biofilm and consequently are more exposed to denture cleanser agents compared with Candida.…”

Evaluation of the Antifungal Effect Vitis vinifera Extract on Candida albicans

“…This because as for the resins to the prosthesis practice, in high scale, as the metallic components that constitute them can be colonized by many microbial species of the oral cavity, such as bacteria, fungal and virus's species. 4,5 The oral candidiasis, also called of stomatitis or popularly thrush, is characterized by the appearance of the white plaques, isolated or grouped adhered to the mucous. They have membranous aspects and, sometimes, are surrounded by halo erythematous.…”

“…Furthermore, some patients are presented as asymptomatic to the infection; however, they normally report various symptoms, as pain, swelling, xerostomia, halitosis and bleeding, symptoms that many times impossible the prosthesis use. 4,7,8 The predisposition to candidiasis is favorable by a range of systemic factors that, directly or indirectly, take to an immunossuppression, as: cancer, prolonged antibiotic therapy; xerostomia; innutrition, age (mainly elderly and children); diabetes; AIDS (Acquired Immunodeficiency Syndrome) and pregnancy. However, local factors can also contribute, among them, the smoking; pre-existing diseases on the oral mucous; precarious hygiene and bad use or maintenance of the dental prosthesis.…”

“…Per definition, the lower concentration capable to individual is compromised, allowing the disordered growing of the fungal and the tissue invasion, characteristic of the opportunist infectious disease. 3,4,9,10,11 The treatment directed to the prosthetic stomatitis include anti fungous topic therapy, caring with the oral hygiene and hygiene procedures and disinfection of the removable prosthesis. However, this treatment many times is not efficient and recurrences occur after the interruption of the medication use.…”
