Figure 5 from Comparison of Bacterial Contamination and Antibacterial Efficacy in Bristles of Charcoal Toothbrushes versus Noncharcoal Toothbrushes: A Microbiological Study | Semantic Scholar (2024)

It is demonstrated that charcoal toothbrushes reduce bacterial contamination and the poor effects on oral health after 1 week of use.

The difference between the two groups was statistically significant in both scenarios when toothbrushes were processed immediately and when processed after 24 h, suggesting the need for drying time for toothbrush to get disinfected before the next use.

84% of miswak toothbrushes are contaminated with persistent bacteria in the first month of use, regardless of storage method, and should be replaced with Miswak toothbrushes every month instead of the previously suggested three months.

It is evident that the microbial contamination of the unprotected toothbrush is higher than that of the toothbrushes that were protected with a cover, and the significance of the same against microbial contamination is unknown.

Immersion of toothbrush in chlorhexidine in CHX for 24 hours and 10 minutes was more effective than other methods for the reduction of L. acidophilus contamination of the toothbrush.

It is illustrated that toothbrushes harbor various microorganisms and that both period of use and user age might affect the microbial composition, as well as the occurrence of antibiotic resistance genes (ARGs) and the impact of different bristle materials on microbial growth and survival.

The microbial contamination of capped and uncapped toothbrushes of adult smoker and non-smoker men was quite high and hence, it increases the risk of dental diseases.

There is insufficient evidence to substantiate the therapeutic and cosmetic marketing claims of charcoal-based mouthwashes, including antimicrobial activity, anti-halitosis, tooth whitening, periodontal disease control, caries reduction and tooth remineralisation, among others.

Comparison of different microbial methods to assess antimicrobial toothpaste properties and evaluate different toothpastes in terms of their antibacterial efficacy against different oral microorganisms in an in vitro setting found that Toothpastes with amine fluoride, and teeth with triclosan resulted in the highest antimicrobial efficacy.

CHX, UV rays and normal saline are effective in a reduction of bacterial count on toothbrushes, according to a statistically significant difference between mean colony-forming unit count pre-Sanitization and post-sanitization in all the groups.

Toothpaste detergents decrease the survival rate of pathogenic species on a toothbrush and can thus limit the risk for bacterial translocation.

The Violight toothbrush holder reduced total CFU by an average of 86% (ANCOVA, P = 0.037) and a tendency was noted for a reduction in total bacterial population as detected by DGGE.

Silver-coating in the current form did not improve any antimicrobial effects against residual bacteria present on the toothbrush head and there was no significant reduction in CFUs by silver-coated toothbrushes.

The antimicrobial spray with chlorhexidine proved to be an effective and practical means for toothbrush disinfection.

Results revealed no statistically significant difference in the quantity of bacteria surviving on toothbrush filaments between control and experimental groups, on both selective and non-selective media, after 30 days.

Toothpaste use reduced the residual microbial contamination for two of three test organisms, but the lower isolation frequencies were not statistically significant.

Toothbrush bristles were contaminated by MS after only one use of dentifrices with or without triclosan, and a dentifrice containing tricrosan significantly reduced bacterial contamination of these toothbrushes.

The Pollenex DS60 Daily Dental Sanitizer was found to be effective in substantially reducing the number of retained bacteria and yeasts as compared to contaminated toothbrushes not treated with such a device.

To overcome a bacterial transmission, a 'one-stage full-mouth disinfection' was recently introduced for the treatment of periodontal infections, which resulted in significant clinical and microbiological improvements when compared with the standard sequential treatment.
