“…Sodium hypochlorite has been reported to be an effective disinfectant. [ 18 ] Sodium hypochlorite is used worldwide for endodontic treatment due to its highly desirable properties as a bactericidal, deodorant and tissue solvent. When NaOCl is added to water, hypochlorous acid is formed, which contains active chlorine, a strong oxidizing agent.…”

Background:Tooth brushing is most common method of maintaining oral hygiene. In removing plaque and other soft debris from the teeth, tooth brushes become contaminated with bacteria, blood, saliva and oral debris. These contaminated tooth brushes can be a source of infection.Aims and objectives:The aim of the present study was to evaluate the presence of microorganisms in the tooth brushes and to investigate the effect of disinfectants such as chlorhexidine gluconate, sodium hypochlorite and water to decontaminate them.Materials and Methods:Twenty-one children were asked to brush their teeth for 5 days with a tooth brush. The tooth brushes were put in Robertson's Cooked Meat broth and were observed for growth of Streptococcal microorganisms. These tooth brushes were then placed in disinfectants such as 0.2% chlorhexidine gluconate (Group I), 1% sodium hypochlorite (Group II) and water (Group III) for 24 hrs and then cultured again. Reduction of growth of microorganisms was seen in Group I, Group II and remnants of growth seen in Group III.Conclusion:We conclude that the use of disinfectant for a tooth brush is a must for every individual at least at regular intervals.

“…Chemical agents, such as cetylpyridinium chloride [11], 1.0% sodium hypochlorite, chlorhexidine, Dettol, essential oil mouthwash, and 3% hydrogen peroxide [12], have been shown to be efficacious in reducing the microbial contamination of toothbrushes. However, there is scant literature on the influence of these chemical agents on toothbrush bristle properties.…”

Background Toothbrushes are the most commonly used mechanical plaque control methods, and they are said to harbor microorganisms if not stored properly following usage. Objective An assessment of the influence of a decontaminating agent (sterile water (control)/chlorhexidine mouthwash/herbal mouthwash) on the properties of toothbrush bristles following storage for 24 hrs by means of scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). Methodology The study involves a total of 24 slim soft toothbrushes (six samples per group) with different decontaminating agents: Group 1: Vented container, Group 2: Sterile water, Group 3: 0.2% Chlorhexidine mouthwash, and Group 4: Herbal mouthwash. The toothbrushes were stored in their respective containers for 24 hours, following which, snippets of toothbrush bristles were collected and tested for the evaluation of wear using SEM and the biochemical alteration occurring in the bristles was assessed using FTIR. Results and conclusion The Group 2 and Group 3 samples showed significant wear (Score 2) under SEM evaluation, and FTIR spectroscopy evaluation revealed that changes occur in the fingerprint region of infrared spectroscopy owing to chemical bond alteration following decontamination. Considering the benefits we acquire in terms of microbial load reduction, decontamination is recommended, though it might necessitate frequent changing of toothbrushes.

“…Essential oil derivates (Listerine) are chemical agents traditionally considered as trustable antiseptics and disinfectants with no secondary effects on host's oral cavity [1,6,8,9]. Listerine is a mouth rinse composed by menthol, ethanol, thymol, eucalyptol (essential oils) and methyl salicylate as active agents; previous investigations reported that this mouth rinse has wide range of disinfectant properties together with CHX [18]. Our results differ from those reported in consulted literature; in our case the average microbial reduction of Listerine was the lowest in comparison to CHX and NaOCl.…”

Objective: To evaluate in the vitro effectiveness of three chemical agents for toothbrush disinfection. Material and Methods: Sixteen new toothbrushes were evaluated, previously sterilized and classified in five experimental groups (n=3) and one item as control. Three chemical agents were assessed: 0.12% Chlorhexidine gluconate (CHX), essential oil mouth rinse (Listerine) and 3.5% Sodium hypochlorite (NaOCl). The five selected strains were inoculated on toothbrushes and incubated for a 24 hours period and 37°C temperature in aerobic conditions. The incubated toothbrushes were immersed for a 15 min period into selected chemical agents and after drying in a controlled air stream, again re-cultured into enriched broth. A comparison was made between the initial and final microorganisms density recovered after chemical disinfection based on Mc Farland scale. The data obtained was compared by descriptive analysis and ANOVA methodology. Results: 3.5% NaOCl was the most effective chemical agent for toothbrush disinfection followed by CHX; Listerine was not effective to eliminate the inoculated bacteria in toothbrushes. Conclusion: 3.5% NaOCl and 0.12% CHX are the most effective chemical agents for toothbrush disinfection and Listerine was only effective against C. albicans.
