Introduction: Toothbrushes play an essential role in oral hygiene. However, toothbrushes can become contaminated through contact with the environment, from the oral cavity, and by toothbrush storage containers. Aim: To evaluate the effectiveness of vinegar, lime, and salt water as potential household decontaminants for toothbrushes. Materials and Methods: In an in vitro study, 120 used toothbrushes were collected and divided into four groups comprising 30 samples each. Group I was treated with plain water alone after use. Group II was treated with salt water. Group III was treated with a solution which contained lime juice. Group IV was treated with vinegar. Treatment duration for the groups was set to be 12 h. After the treatment, the brush heads of the four groups were incubated in brain-heart infusion agar at 37°C for 24 h. Statistical analysis was performed using the Statistical Package for the Social Sciences version 20.0 software. One-way analysis of variance and Bonferroni post hoc analysis were performed for multiple comparisons. Results: Vinegar group showed statistically significant result for decontamination of toothbrushes when compared to other test and control agents. Conclusion: Commonly used household materials can be potential decontaminants for toothbrushes. The results of this study showed that vinegar was the most effective decontamination agent followed by lime and salt water.
