|
The toothbrush is essential for removing dental plaque and the proper toothbrush hygiene care is important to optimize oral health. The majority of the microorganisms transferred to the toothbrush from the oral cavity or another toothbrush. However, recommended toothbrush hygiene care had a limitation to adapt in daily basis.. In this study we conducted the toothbrush hygiene care by controlling the rinsing temperature, which the oral bacteria are sensitive. In brief, the contaminated toothbrush by Streptococcus mutans were washed ordinary methods and finally washed in three different conditioned, 1) Tap, 2) Ice and 3) Hot. The treated toothbrush was rinsed in sterilized deionized water and smeared on the agar plate. After 24 hours, the CFU was counted. The tests were conducted three times. The statistical analysis was using one-way ANOVA following by Tukey. From the results, the Hot group showed the significant difference when compare to ‘Ice’ and ‘Tap’ and all groups were significantly differences(p<0.05). Although there were limitations in this study such as using one bacteria and the ‘Hot’ groups could damage the brush. However, there was significant meaning to hygiene care of a toothbrush in daily basis without further sanitizer. The further study on general toothbrush hygiene care with clinical
evidence was suggested.
