This study was undertaken to 1) compare the prevalence of gingival inflammation and dental calculus in adolescents with early-onset periodontitis and their matched controls and 2) assess and compare the relationship between the presence of dental calculus and the extent of gingival bleeding and attachment loss in these subjects. The study group consisted of 1,285 13 to 20 year-old individuals, 651 males and 634 females, selected from a national survey of the oral health of U.S. adolescents in 1986/1987. It included 709 (55.2%) Blacks, 224 (17.4%) Hispanics, and 352 (27.4%) Whites. Eighty-nine subjects had localized or generalized juvenile periodontitis (JP), 218 had incidental attachment loss (IAL), and 978 were without clinical attachment loss (controls). The controls were matched to cases on gender, race, age, and geographic location. The subjects were examined clinically to assess the percentage of sites with gingival bleeding and supragingival calculus only and subgingival calculus with or without supragingival calculus. The IAL and JP groups had significantly more gingival bleeding and subgingival calculus than the controls. Also, the JP group had significantly higher prevalence of both conditions than the IAL group. The percentage of sites with supragingival calculus was not different between the groups, but varied by ethnicity. Hispanics with JP had the highest percentage of sites with gingival bleeding and subgingival calculus, and the lowest percentage of sites with only supragingival calculus. The results demonstrate that gingival inflammation and subgingival calculus are associated with early periodontal breakdown, and contradict earlier reports of early-onset periodontitis not being associated with these factors.
1）比较早发性牙周炎青少年及其匹配对照组中牙龈炎症和牙结石的患病率；2）评估并比较这些受试者中牙结石的存在与牙龈出血程度及附着丧失之间的关系。研究组由1986/1987年美国青少年口腔健康全国调查中选取的1285名13至20岁个体组成，其中男性651名，女性634名。包括709名（55.2%）黑人、224名（17.4%）西班牙裔和352名（27.4%）白人。89名受试者患有局限性或广泛性青少年牙周炎（JP），218名有偶发性附着丧失（IAL），978名无临床附着丧失（对照组）。对照组在性别、种族、年龄和地理位置上与病例相匹配。对受试者进行临床检查，以评估仅存在牙龈出血和龈上牙结石的部位百分比，以及存在或不存在龈上牙结石的龈下牙结石情况。IAL组和JP组的牙龈出血和龈下牙结石明显多于对照组。此外，JP组这两种情况的患病率均显著高于IAL组。各组之间龈上牙结石部位的百分比没有差异，但因种族而异。患有JP的西班牙裔牙龈出血和龈下牙结石部位的百分比最高，仅龈上牙结石部位的百分比最低。结果表明，牙龈炎症和龈下牙结石与早期牙周破坏有关，这与早期关于早发性牙周炎与这些因素无关的报道相矛盾。
