A total of 2214 sites from incisors, cuspids, and premolars were studied in 46 adult periodontitis patients following treatment consisting of plaque control and root debridement. The periodontal status at 24 months was used as baseline for observations during the subsequent 24-48 month interval which included 4 recall visits for debridement at the 24-, 30-, 36-, and 42-month time points. The data were analyzed for pooled groups of sites of different probing depth at 24 months: less than or equal to 3.5 mm, 4.0-6.5 mm, and greater than or equal to 7.0 mm. The results showed little change during the 24-48 month interval in mean scores for bleeding on probing, probing depth, and probing attachment level for all 3 groups of sites. Individual sites with probing attachment loss during the 24-48 month period were identified. The frequency of such sites was similar, irrespective of 24-month probing depth. The sites identified with probing attachment loss during the 24-48 month interval generally differed in location from those identified as having probing attachment loss during the preceeding 0-24 month period. Often, the loss of probing attachment during the 24-48 month interval seemed to be a reversal of a prior gain in probing attachment during the 0-24 month interval. This study in non-molar teeth of subjects with generally good level of compliance failed to demonstrate that sites with deeper probing depth were more difficult to maintain than shallower sites.
在46名接受了包括菌斑控制和根面清创术治疗的成人牙周炎患者中，对来自切牙、尖牙和前磨牙的总共2214个位点进行了研究。将24个月时的牙周状况作为后续24至48个月期间观察的基线，该期间包括在24、30、36和42个月时间点进行的4次清创复诊。对24个月时不同探诊深度的位点合并组数据进行分析：小于或等于3.5毫米、4.0至6.5毫米以及大于或等于7.0毫米。结果显示，在24至48个月期间，所有3组位点的探诊出血、探诊深度和探诊附着水平的平均分数变化不大。确定了在24至48个月期间有探诊附着丧失的个体位点。无论24个月时的探诊深度如何，此类位点的频率相似。在24至48个月期间确定有探诊附着丧失的位点，其位置通常与在之前0至24个月期间确定为有探诊附着丧失的位点不同。通常，在24至48个月期间探诊附着的丧失似乎是0至24个月期间探诊附着先前增加的逆转。这项针对依从性总体良好的受试者的非磨牙研究未能证明，探诊深度较深的位点比探诊深度较浅的位点更难维持。
