This study analyzed the data on gingival bleeding, calculus, and periodontal attachment loss in 14-17 year-old children who participated in the National Survey of Oral Health in U.S. School Children conducted by the NIDR during 1986-87. The 11,111 children in the sample represent an estimated 13 million U.S. school children in this age group. The prevalence of gingivitis was approximately 60% for children in this age group. The percent of examined sites with gingivitis per child, however, was less than 6%. There was an overall age associated decline in prevalence of gingivitis. Males, in general, and children in the category of "blacks and other races" showed higher prevalence of gingivitis. Prevalence of gingivitis was slightly higher at buccal than mesial sites and was most common in molar areas in the maxilla and incisor areas in the mandible. The prevalence of supragingival calculus alone was nearly 34% and subgingival calculus was approximately 23%. The percent of teeth with calculus per child was approximately 8 for the former and 4 for the latter type of calculus. There was a slight age-associated increase in prevalence of latter type of calculus. Males and children in the category of "blacks and other races" showed higher prevalence of both types of calculus. The Mean periodontal attachment loss, determined by probing with #2-12 probe, was 0.33 mm (0.26 mm for buccal and 0.40 mm for mesial surfaces) and varied very little by age, sex or race. The teeth most frequently affected by attachment loss of 2 mm or more were maxillary molars and bicuspids, followed by mandibular molars and cuspids.

本研究分析了牙龈出血，牙石， 牙周附着丧失的14-17岁的儿童谁参加了 美国儿童口腔健康全国调查， 1986- 1987年期间的NIDR。样本中的11，111名儿童代表了 估计有1300万美国学龄儿童在这个年龄段。 牙龈炎的患病率约为60%的儿童在这个年龄段 组然而，每个孩子牙龈炎的检查部位的百分比， 不到6%。总体患病率与年龄相关下降 牙龈炎一般来说，男性和“黑人”类别的儿童 和其他种族的人的牙龈炎患病率更高。之时尚 牙龈炎在颊侧略高于近中部位， 常见于上颌骨的臼齿区域和下颌骨的门牙区域。的 单纯龈上结石的患病率接近34%， 结石约占23%。每年有牙石的牙齿百分比 前者的孩子大约8岁，后者的孩子大约4岁。 微积分年龄相关的患病率略有增加， 后一种微积分。属于“黑人和 其他种族”的人这两种微积分的患病率都更高。平均 牙周附着丧失，通过用#2-12探针探测确定， 0.33 mm（颊侧0.26 mm，近中面0.40 mm）， 年龄、性别或种族差异很小。最常受影响的牙齿 附着丧失2 mm或以上的是上颌磨牙和双尖牙， 其次是下颌磨牙和尖牙。
