To assess the efficacy of the antimicrobial properties of charcoal vs. non-charcoal toothbrushes and the level of bacterial contamination in the oral cavity using a charcoal toothbrush.
This was a randomized, double-blind controlled study in which both male and female subjects aged from 18 to 35 were included ( = 30; 15 males and 15 females). The subjects were selected from (students) of Riyadh Elm University in Riyadh, Saudi Arabia. Subjects were informed about the study and signed the consent form before participation. From January to April 2019, subjects were given charcoal and non-charcoal toothbrushes.
The Wilcoxon signed rank test showed that there was a significant difference in bacterial counts between non-charcoal and charcoal toothbrushes ( = 0.000). Of the subjects, 70% showed a decrease in the number of bacterial counts while 30% showed no increase in bacterial counts. There was a statistically significant decrease in the number of bacteria in the gingival crevicular fluid (GCF) with charcoal treatment ( < 0.001). Of the subjects, 96.6% showed a decrease in the count of bacteria in GCF after using a charcoal toothbrush. Only 3.3% of the subjects had the similar counts of bacteria in GCF after using the charcoal toothbrush.
The study demonstrates that charcoal toothbrushes reduce bacterial contamination and the poor effects on oral health after 1 week of use.
评估炭质牙刷与非炭质牙刷抗菌性能的疗效以及使用炭质牙刷时口腔内的细菌污染水平。
这是一项随机、双盲对照研究，纳入了年龄在18至35岁之间的男性和女性受试者（n = 30；15名男性和15名女性）。受试者从沙特阿拉伯利雅得伊玛目大学的（学生）中选取。在参与研究前，向受试者告知了研究情况并让其签署了知情同意书。2019年1月至4月，为受试者提供了炭质牙刷和非炭质牙刷。
Wilcoxon符号秩检验显示，非炭质牙刷和炭质牙刷的细菌计数存在显著差异（P = 0.000）。在受试者中，70%的人细菌计数减少，而30%的人细菌计数没有增加。炭质处理后龈沟液（GCF）中的细菌数量有统计学意义的下降（P < 0.001）。在使用炭质牙刷后，96.6%的受试者龈沟液中的细菌计数减少。使用炭质牙刷后，只有3.3%的受试者龈沟液中的细菌计数相似。
该研究表明，炭质牙刷在使用1周后可减少细菌污染并对口腔健康产生不良影响。
