To improve the assessment of plaque present on teeth, a new index, based on the original Modified Navy Plaque Index, has been developed. The primary modifications to the original Modified Navy Plaque Index were: (1) extending areas F (distal) and D (mesial) into the region just below the interproximal contact point, and (2) extending areas C and A so as to increase the gumline (or marginal gingiva) region. The new index assesses the amount of plaque in the tooth area bounded by the tooth contact, the free gingival margin, and mesial or distal line angles. The use of this new index enables the examiner to evaluate and record both the gumline (or marginal areas) and interproximal areas of the tooth, thus giving these an anatomical areas an increased importance. A pilot clinical assessment study was conducted to utilize this new index in evaluating the plaque removal efficacy of five manual toothbrushes. The results from this pilot study indicated that, when the new plaque scoring index was used, significant differences between pre-toothbrushing and post-toothbrushing plaque scores (as well as among toothbrush groups) could be demonstrated. Further, these differences (plaque removal efficacy) were demonstrated on an interproximal (mesial and distal) basis and a gumline (or gingival margin) basis, as well as on a whole mouth basis.
为了改进对牙齿上菌斑的评估，在原始改良海军菌斑指数的基础上开发了一种新的指数。对原始改良海军菌斑指数的主要修改是：（1）将区域F（远中）和D（近中）扩展到邻面接触点正下方的区域，以及（2）扩展区域C和A以增加牙龈缘（或边缘龈）区域。新指数评估由牙齿接触、游离牙龈缘以及近中或远中线角界定的牙齿区域中的菌斑量。使用这种新指数使检查者能够评估和记录牙齿的牙龈缘（或边缘区域）和邻面区域，从而使这些解剖区域具有更高的重要性。进行了一项初步临床评估研究，以利用这种新指数评估五款手动牙刷的菌斑清除效果。这项初步研究的结果表明，当使用新的菌斑评分指数时，可以证明刷牙前和刷牙后菌斑评分之间（以及牙刷组之间）存在显著差异。此外，这些差异（菌斑清除效果）在邻面（近中和远中）、牙龈缘（或牙龈边缘）以及全口基础上都得到了体现。
