约300名年龄在20-79岁之间的受试者被招募来进行牙周治疗效果的纵向研究。基线检查的结果早前已报告。在基线检查之后，受试者在没有治疗的情况下进行了24个月的监测。12个月和24个月后复查。包括第三磨牙在内的所有牙齿都被纳入检查范围。在每颗牙齿的4个表面评估牙菌斑的存在，在每颗牙齿的6个位置评估牙龈炎、探针袋深度、探针附着水平。在基线检查的受试者样本中，57人未能在第一次，第二次或两次重新检查中返回。对应答者和非应答者在基线时的牙周状况进行分析。对20至79岁受试者的随访检查结果显示，在2年的时间里，样本在牙周病特征的一系列不同参数方面只有轻微的变化。因此，探查袋深度和探查附着水平的平均值在基线和复查后1年和2年之间没有变化。然而，即使平均值只发生了微小的变化，每个年龄组中的某些受试者的牙周状况得到了改善，而其他受试者的牙周状况则恶化了。此外，复查的结果显示，菌斑水平的改善与牙龈炎之间有很强的相关性。龈上菌斑水平与探探深度和附着水平的变化之间的关系较弱。
About 300 subjects, 20-79 years of age were recruited for a longitudinal study on the effect of periodontal therapy. The result of a baseline examination have been reported earlier. Following this baseline examination, the subjects were monitored for 24 months without therapy. Re-examinations were performed after 12 and 24 months. All teeth including the 3rd molars were included in the examinations. Presence of plaque was assessed at 4 surfaces per tooth and gingivitis, probing pocket depth, probing attachment levels were assessed at 6 locations per tooth. Out of the subject sample examined at baseline, 57 individuals failed to return for either the 1st, the 2nd or both re-examinations. An analysis was performed regarding the periodontal status at baseline, of the respondents and non-respondents. The results from the follow-up examinations of the participating 20 to 79 year-old subjects revealed that the sample underwent, during a 2-year period, only minor changes with respect to a series of different parameters characteristic of periodontal disease. Thus, the mean values of probing pocket depth and probing attachment level failed to change between baseline and the re-examinations after 1 and 2 years. Even if the mean values underwent only minor changes, however, certain subjects within each age category improved their periodontal conditions, whereas other subjects worsened. Furthermore, the findings of the re-examinations revealed that there was a strong correlation between improving plaque levels and gingivitis. The relationship between supragingival plaque levels and changes with respect to probing depth and attachment levels were weak.
