“…The use of a toothbrush cap has also been reported to increase bacterial survival on toothbrushes. 2,5,18 Nascimento et al 19 investigated the effectiveness of three antimicrobial mouth rinses for toothbrush disinfection under in vivo conditions. The participants of that study stored their toothbrushes in closed containers to avoid external contamination.…”

The aim of this study was to evaluate the knowledge and behavior of dentists regarding toothbrush disinfection. This study included 147 dentists (88 women and 59 men) who were actively employed at a dental school in Ankara, Turkey. Participants were asked to fill out a standard questionnaire, which contained questions regarding their demographics, brushing habits, toothbrush storage and disinfection habits, toothpaste use, knowledge about toothbrush disinfection, and whether they advised their patients about toothbrush storage. Descriptive statistics were calculated, and statistical analyses were performed with t-tests, chi-squared tests, and Fisher exact tests, where appropriate. Among the 147 surveyed dentists, 62.6% and 85.7% reported that they did not have any knowledge about toothbrush disinfection and did not disinfect their toothbrushes, respectively. However, approximately two thirds of surveyed dentists thought that toothbrush disinfection should be performed by everyone, including healthy individuals. Significant associations were found between knowledge about toothbrush disinfection and the professional title of dentists, how they stored their toothbrushes, and whether their toothbrushes were in contact with each other during storage (p < 0.05). A minority of dentists reported that they disinfected their toothbrushes.

“…Furthermore, Nascimento et al (2014) in their study found that 8 h immersion in Periogard solution was highly effective against bacterial toothbrush contamination. According to their study we can determine that Periogard in spray form was considered more economical than 8 h immersion in Periogard solution with the same efficacy.…”

“…Future studies should assess the localization of the biofilm, and the effect of specific cleaning procedures to reduce or prevent biofilm build-up, as the currently recommended approach to empty and carefully swab the container with a clean paper tissue after each use is inefficient. For example, specific cleaning procedures (e.g., simple immersion in 0.12% chlorhexidine gluconate or 1% sodium hypochlorite for 20 h) have been described to reduce successfully the bacterial load on toothbrushes (Balappanavar et al, 2009;do Nascimento et al, 2014;Mehta et al, 2007;Nelson-Filho et al, 2000, 2006. Furthermore, the possible impact of using SAF with a mouth-rinse instead of water on the bacterial colonization of the nozzle and/or the device should be assessed, as the manufacturer in fact recommends using the SAF with tap water or with a mouth-rinse.…”

Objectives: The present proof-of-principle study assessed whether daily use of a power-driven water flosser (Sonicare AirFloss; SAF) leads to bacterial colonization in the nozzle and/or the device, resulting in contaminated water-jet.Material and Methods: In five participants, saliva samples at baseline and waterjet samples of devices used daily with bottled water for 3 weeks (test) were collected.Additionally, water-jet samples from devices used daily with bottled water extraorally for 3 weeks (positive control) and from brand new devices (negative control), as well as samples from newly opened and 1-and 3-week opened water bottles were collected. Colony forming units (CFU) were recorded after 48 h culturing and 20 oral pathogens were assessed by polymerase chain reaction-based analysis.Results: Distinct inter-individual differences regarding the number of detected bacteria were observed; water-jet samples of test devices included both aerobic and anaerobic bacterial species, with some similarities to the saliva sample of the user.Water-jet samples from positive control devices showed limited number of aerobic and anaerobic bacterial species, while the samples from negative control devices did not show any bacterial species. Very few aerobic bacteria were detected only in the 3-week-old bottled water samples, while samples of newly and 1-week opened water bottles did not show any bacterial growth. Conclusions:The present proof-of-principle study showed that daily use of a powerdriven water flosser for 3 weeks resulted in bacterial colonization in the nozzle and/or device with both aerobic and anaerobic, not only oral, species, that are transmitted via the water-jet.

Effectiveness of three antimicrobial mouthrinses on the disinfection of toothbrushes stored in closed containers: a randomized clinical investigation by DNA Checkerboard and Culture

Abstract: Culture and DNA Checkerboard showed positive signals of bacterial contamination. Mouthrinses that contains 0.12% of chlorhexidine gluconate were more effective in reducing bacterial colonisation on the toothbrushes.
