Out of a group of 30 patients aged from 11 to 15 years, 10 each were treated with either fixed appliances, or removal plates, or by functional orthodontics. Prior to the beginning of the treatment, and one week and six weeks thereafter, pocket depth, SB index, sulcus fluid flow rate, and OH index were recorded. The inflammatory symptoms of the gingiva were shown to be a function of the OH index. Moreover, the OH index grew worse during orthodontic treatment, especially in the group with fixed appliances.
在一组年龄为11至15岁的30名患者中，10名分别接受了固定矫治器、活动矫治器或功能性正畸治疗。在治疗开始前以及治疗开始后1周和6周，记录牙周袋深度、龈沟出血指数、龈沟液流速和口腔卫生指数。牙龈的炎症症状表现为口腔卫生指数的函数。此外，正畸治疗期间口腔卫生指数变差，尤其是在使用固定矫治器的组中。
