Evaluation of toothbrush disinfection via different methods

Abstract

The aim of this study was to compare the efficacy of using a dishwasher or different chemical agents, including 0.12% chlorhexidine gluconate, 2% sodium hypochlorite (NaOCl), a mouthrinse containing essential oils and alcohol, and 50% white vinegar, for toothbrush disinfection. Sixty volunteers were divided into five experimental groups and one control group (n = 10). Participants brushed their teeth using toothbrushes with standard bristles, and they disinfected the toothbrushes according to instructed methods. Bacterial contamination of the toothbrushes was compared between the experimental groups and the control group. Data were analyzed by Kruskal-Wallis and Duncan's multiple range tests, with 95% confidence intervals for multiple comparisons. Bacterial contamination of toothbrushes from individuals in the experimental groups differed from those in the control group (p < 0.05). The most effective method for elimination of all tested bacterial species was 50% white vinegar, followed in order by 2% NaOCl, mouthrinse containing essential oils and alcohol, 0.12% chlorhexidine gluconate, dishwasher use, and tap water (control). The results of this study show that the most effective method for disinfecting toothbrushes was submersion in 50% white vinegar, which is cost-effective, easy to access, and appropriate for household use.

Control of bacterial biofilms formed on pacifiers by antimicrobial solutions in spray

“…In view of low toxicity, low cost and a viable home-use application, apple vinegar and hydrogen peroxide showed the best antimicrobial activity against reference strains in screening tests (agar well diffusion and MIC/MMC evaluation). Vinegar and hydrogen peroxide have been suggested as interesting alternatives for the disinfection of other materials 19,20,[25][26][27][28][29] .…”

Effectiveness of Use of Ultraviolet Sanitizing Devices for Reduction of Bacterial Colonies on Toothbrushes

“…UV sanitation tools can serve as decontamination of toothbrushes that can reduce exposure to bacteria and viruses. [1] Therefore, this study was conducted using UV sanitation tools as decontamination of toothbrushes that can reduce the growth of microorganisms and prevent cross-infection.…”

“…As a result, they may be exposed to enteric bacteria dispersed by aerosols. [1] The oral cavity contains 700 types of microorganisms, which are commonly found in toothbrushes during use and originating from toothbrush storage areas. The toothbrush is important for oral hygiene daily.…”

Evaluation of Effectiveness of Home Remedies for Toothbrush Decontamination using Vinegar and Vinegar with Common Salt

“…10 In this regard, when toothbrush decontaminating efficacy with 50% white vinegar was measured in vitro and in vivo, it has been found to be promising against the specifically tested bacteria. 6,13 On the contrary, during exploration of food preservation techniques, it has also been proven that addition of 3.5% sodium chloride to vinegar increases the antibacterial activity. 14 This present study is aimed to evaluate if vinegar with/without sodium chloride could be used as an alternative to chlorhexidine gluconate for disinfection of toothbrushes.…”
