The aim of this study was to assess the caries experience and tooth loss over 6 years in subjects with early-onset periodontitis as compared to their matched controls, and to describe the characteristics of teeth lost during this period. A multi-stage probability sample representing 8th to 12th grade U.S. schoolchildren were screened during the 1986/1987 school year to identify subjects with early-onset periodontitis (cases). The examination included measuring the clinical attachment level, presence of caries and dental restorations, and tooth loss. A random sample of controls without early-onset periodontitis were selected for a follow-up examination and were matched to cases on gender, race, age, and geographic location. A total of 266 subjects, with a mean age of 16 years at baseline, were examined during the 1992/1993 school year and were classified into localized (LJP) and generalized juvenile periodontitis (GJP), incidental attachment loss (IAL), and control groups. Whites had more caries experience than Blacks and Hispanics, but there were no significant differences in tooth loss between the ethnic groups. The LJP and the IAL groups, respectively, had higher and lower overall caries experience than the control group. The LJP group had a significantly higher number of missing teeth at follow-up, and exhibited more extensive tooth mortality during 6 years than the control group. The GJP group also showed more tooth loss than the control group, but the difference was not statistically significant. In the LJP, GJP, IAL, and control groups, respectively, 43%, 32%, 26%, and 18% of the subjects lost teeth over 6 years due to disease. The findings showed differences in caries activity between the early-onset periodontitis groups and a variation by race. The findings suggest that loss of periodontal support was the principal cause for tooth loss in the LJP and GJP groups, and that dental caries was the principal cause for tooth extraction in the IAL and the control groups.
本研究的目的是评估早发性牙周炎患者与其匹配的对照组在6年期间的龋病经历和牙齿缺失情况，并描述在此期间缺失牙齿的特征。在1986/1987学年对代表美国8至12年级学童的多阶段概率样本进行筛查，以确定早发性牙周炎患者（病例）。检查包括测量临床附着水平、龋病和牙齿修复体的存在情况以及牙齿缺失情况。随机抽取无早发性牙周炎的对照组进行随访检查，并根据性别、种族、年龄和地理位置与病例进行匹配。在1992/1993学年对总共266名基线平均年龄为16岁的受试者进行了检查，并将其分为局限性（LJP）和广泛性青少年牙周炎（GJP）、偶然性附着丧失（IAL）和对照组。白人的龋病经历比黑人和西班牙裔更多，但不同种族之间的牙齿缺失情况没有显著差异。LJP组和IAL组的总体龋病经历分别高于和低于对照组。LJP组在随访时缺失牙齿的数量显著更多，并且在6年期间的牙齿死亡率比对照组更高。GJP组也比对照组显示出更多的牙齿缺失，但差异无统计学意义。在LJP、GJP、IAL和对照组中，分别有43%、32%、26%和18%的受试者在6年期间因疾病而牙齿缺失。研究结果显示早发性牙周炎组之间的龋病活动存在差异，并且因种族而异。研究结果表明，牙周支持丧失是LJP组和GJP组牙齿缺失的主要原因，而龋病是IAL组和对照组牙齿拔除的主要原因。
