Medically healthy subjects (N = 103), 10-32 years of age, with localized (juvenile periodontitis = JP) or generalized (severe periodontitis = SP) advanced periodontal disease were analyzed for interrelationships of sex, race, age and clinical findings. Females predominated (2:1) in both JP and SP. There were significantly more subjects of the black race in JP, but when age was included as a cofactor the race distinction became insignificant. While whole mouth Plaque and Gingival Indices were lower in JP, these values at sites with attachment loss were equally high in both groups. Extent of disease was significantly related to both plaque and age in SP, and to plaque but not to age in JP. This suggests the existence of a factor(s) in JP which interfere(s) with the age-plaque-disease relationships found in SP and present in adult periodontitis. Contrary to implications of some definitions of JP, periodontal attachment loss was strongly associated with plaque and gingival inflammation in both localized and generalized patterns of disease.
对103名年龄在10至32岁之间、患有局限性（青少年牙周炎=JP）或广泛性（重度牙周炎=SP）晚期牙周病的身体健康受试者进行了性别、种族、年龄和临床检查结果之间相互关系的分析。在JP和SP中，女性均占多数（比例为2:1）。JP中黑人受试者明显更多，但将年龄作为一个协变量纳入分析时，种族差异变得不显著。虽然JP的全口菌斑指数和牙龈指数较低，但两组中存在附着丧失部位的这些值同样高。在SP中，疾病程度与菌斑和年龄均显著相关，而在JP中，疾病程度与菌斑相关，但与年龄无关。这表明在JP中存在一个因素，该因素干扰了在SP以及成人牙周炎中发现的年龄-菌斑-疾病关系。与JP的一些定义所暗示的情况相反，在局限性和广泛性疾病模式中，牙周附着丧失均与菌斑和牙龈炎症密切相关。
