Abstract

OBJECTIVES

The purpose of this study was to compare the efficacy of prebreakfast tooth brushing (PrBTB) and postbreakfast tooth brushing (PoBTB) with or without a prebrushing rinse in caries prevention through the estimation of count.

MATERIALS AND METHODS

Sixty consenting dental students were divided into three age-matched groups of 20 each and instructed to follow prebreakfast, postbreakfast tooth brushing, and prebreakfast rinsing plus PoBTB using the Bass technique. Plaque samples were collected at the start and at the end of every quarter for a total of 6 quarters (18 months) for the evaluation of colony-forming unit (CFU) counts. The decayed missing filled surface (DMFS) index of participants was also recorded and compared at the beginning and end of the study period.

RESULTS

The post-breakfast tooth brushing group with pre-breakfast rinse (RPoBTB) and without pre-breakfast rinse (PoBTB) showed a highly significant reduction in total CFU counts per ml (38% and 29% respectively) at the end of the study. The changes in DMFS value were not significant and did not show any correlation with the counts.

CONCLUSION

Our study revealed that PoBTB with or without a prebreakfast rinse reduces the total counts of the cariogenic bacteria more efficiently than PrBTB. Although further proof in the form of clinical trials is essential, this study provides the proof of concept for a minor change in the tooth brushing habit, which can significantly enhance caries prevention.

摘要

目的

本研究旨在通过估计[细菌名称]计数，比较早餐前刷牙（PrBTB）和早餐后刷牙（PoBTB）在有无早餐前漱口情况下对预防龋齿的效果。

材料与方法

60名同意参与的牙科专业学生被分为三个年龄匹配组，每组20人，并被指导使用巴斯刷牙法分别进行早餐前刷牙、早餐后刷牙以及早餐前漱口加早餐后刷牙。在每季度开始和结束时收集牙菌斑样本，共收集6个季度（18个月），用于评估[细菌名称]菌落形成单位（CFU）计数。还记录并比较了研究期间参与者的龋失补牙面（DMFS）指数在开始和结束时的情况。

结果

在研究结束时，早餐前漱口的早餐后刷牙组（RPoBTB）和未进行早餐前漱口的早餐后刷牙组（PoBTB）每毫升[细菌名称]CFU总数均显著降低（分别为38%和29%）。DMFS值的变化不显著，且与[细菌名称]计数无任何相关性。

结论

我们的研究表明，无论有无早餐前漱口，PoBTB比PrBTB更有效地降低了致龋菌的总数。尽管以临床试验形式提供进一步证据至关重要，但本研究为刷牙习惯的微小改变提供了概念验证，这种改变可显著增强龋齿预防效果。
