Abstract

OBJECTIVE

The purpose of the present study was to test the effectiveness of a finger toothbrush (I-Brush) in removing plaque compared with a flat-trimmed manual toothbrush.

MATERIAL AND METHODS

For this study, 37 subjects were selected, without previous experience of the use of the I-Brush. Each subject received a finger brush (I-Brush), a manual toothbrush (Butler GUM 311), two written brushing instructions for both types of brushes, and a brush calendar. Subjects were given a period of 3 weeks to become familiar with the two types of brushes. During this period, the subjects were instructed to use the two types of brushes on alternate days. The brush calendar helped as a reminder and served to ensure compliance. No instructions regarding brushing time or frequency of brushing were given to the subjects, except that they should conform to their usual oral habits. After 3 weeks, all subjects were asked to abstain from oral hygiene procedures for 48 h prior to the experiment. In this experiment, the amount of dental plaque was scored by a trained examiner. The examiner (N.A.M.R.) used the modified Silness & Loe (1964) plaque index at six sites per tooth. After scoring, each subject received a new finger brush and a new manual toothbrush. The subjects brushed according to a split mouth protocol. Two contra-lateral quadrants were chosen randomly and were brushed with one randomly chosen brush and the two opposing contra-lateral quadrants with the alternate brush. The brushing was performed under supervision in front of a mirror. The available time for brushing was 2 min. for the entire dentition. Finally, the remaining plaque was scored again.

RESULTS

The overall reduction in plaque was 79% for the manual toothbrush and 62% for the finger brush. The plaque removing efficacy of the finger brush was poorest at the approximal vestibular surfaces (55% plaque reduction) compared with the manual toothbrush (77% plaque reduction).

CONCLUSION

The plaque reduction of the finger brush is not an acceptable alternative to the use of a regular manual toothbrush.

摘要

目的

本研究旨在测试指套牙刷（I-Brush）与平头手动牙刷相比在去除牙菌斑方面的有效性。

材料与方法

本研究选取了37名此前没有使用过I-Brush经验的受试者。每位受试者收到一支指套牙刷（I-Brush）、一支手动牙刷（Butler GUM 311）、两份针对两种牙刷的书面刷牙指导以及一份刷牙日历。受试者有3周时间来熟悉这两种牙刷。在此期间，指导受试者隔天使用这两种牙刷。刷牙日历起到提醒作用，有助于确保受试者遵守要求。除了受试者应遵循其通常的口腔卫生习惯外，未对他们给出关于刷牙时间或刷牙频率的指导。3周后，要求所有受试者在实验前48小时停止口腔卫生护理程序。在本实验中，由一名经过培训的检查人员对牙菌斑量进行评分。检查人员（N.A.M.R.）使用改良的Silness & Loe（1964年）菌斑指数，对每颗牙齿的六个部位进行评分。评分后，每位受试者收到一支新的指套牙刷和一支新的手动牙刷。受试者按照分口方案刷牙。随机选择两个对侧象限，用随机选择的一种牙刷刷牙，另外两个相对的对侧象限用另一种牙刷刷牙。刷牙在镜子前监督下进行。整个牙列的刷牙可用时间为2分钟。最后，再次对剩余牙菌斑进行评分。
