Toothbrushing is the most commonly used method to physically remove dental plaque. However, there are many areas of the mouth that are difficult to reach with a toothbrush. The type of toothbrush is a critical factor influencing the effectiveness of oral care. The purpose of the study was to evaluate a toothbrush with a thin head, slender-neck and super-tapered bristles to target hard-to-reach areas in the oral cavity for reducing dental plaque and gingivitis.
This crossover study included 58 adults aged 20 years and older. All participants were randomly assigned to use test and control toothbrushes (the latter had a normal head and round bristles) for two 4-week phases. Participants brushed their teeth twice daily in their habitual manner. At the start and end of each phase the Silness-Lӧe plaque index (PI), Lӧe -Silness gingival index (GI) and bleeding-on-probing index (BOP) were assessed and performed plaque fluorescence tests using quantitative light-induced fluorescence technology.
After using the test toothbrush, PI, GI and BOP decreased by 25%, 30% and 48%, respectively (P < 0.05). For the rearmost molars, PI, GI and BOP decreased by 18%, 26% and 47%, respectively (P < 0.05). For the implants, GI and BOP decreased by 31% and 57%, respectively (P < 0.05). The plaque fluorescence tests indicated that after using the test toothbrush, the dental plaque area for the anterior teeth and the simple plaque score for the rearmost molars decreased by 25% (P < 0.05) and 14% (P = 0.527), respectively.
The test toothbrush was markedly better than the control toothbrush at reducing dental plaque and gingivitis. In particular, the test toothbrush produced an excellent reduction in dental plaque and gingivitis for the rearmost molars and the implants.

刷牙是最常用的物理方法来去除牙菌斑。然而，口腔中有许多难以用牙刷触及的部位。牙刷的类型是影响口腔护理效果的关键因素。本研究的目的是评估一种头部较细、颈部细长、刷毛超尖的牙刷，以减少口腔内难以触及的区域的牙菌斑和牙龈炎。
本交叉研究纳入了 58 名年龄在 20 岁及以上的成年人。所有参与者被随机分配在两个 4 周阶段使用测试和对照牙刷（后者有一个正常的头部和圆形刷毛）。参与者按照习惯每天刷牙两次。在每个阶段的开始和结束时，评估 Silness-Lӧe 菌斑指数（PI）、Lӧe -Silness 牙龈指数（GI）和探诊出血指数（BOP），并使用定量光诱导荧光技术进行菌斑荧光测试。
使用测试牙刷后，PI、GI 和 BOP 分别下降了 25%、30%和 48%（P<0.05）。对于最后一颗磨牙，PI、GI 和 BOP 分别下降了 18%、26%和 47%（P<0.05）。对于植入物，GI 和 BOP 分别下降了 31%和 57%（P<0.05）。菌斑荧光测试表明，使用测试牙刷后，前牙的牙菌斑面积和最后一颗磨牙的简单菌斑评分分别减少了 25%（P<0.05）和 14%（P=0.527）。
测试牙刷在减少牙菌斑和牙龈炎方面明显优于对照牙刷。特别是，测试牙刷对最后一颗磨牙和植入物的牙菌斑和牙龈炎有很好的减少作用。
