The present investigation describes probing pocket depth, probing attachment level and recession data from 319 randomly selected subjects, aged 20-79 years, from Ushiku, Japan. The findings are reported as mean values, frequency distributions and percentile plots of the 3 parameters at buccal, interproximal and lingual surfaces of single rooted (incisors, canines, premolars) and molar teeth. Inter-as well as intra-examiner errors for probing pocket depth and probing attachment levels were assessed and found to be small. The data reported revealed that practically all subjects studied had one or more sites in the dentition affected by destructive periodontal disease and that the severity of disease increased with age. It was further observed that in each age group, molars had suffered more attachment loss than single rooted teeth and that the interproximal surfaces as a rule had lost more periodontal tissue support than corresponding buccal and lingual surfaces. The attachment loss difference observed between different surfaces of a given tooth or a group of teeth, however, was comparatively small. In the age groups between 20-59 years, advanced destructive periodontal disease was found in a small subgroup of the subject sample, while after the age of 60 years, widespread destructive periodontitis was common. An attempt was made to examine the progression of destructive disease with age by comparing the frequency distributions of sites with attachment loss of greater than or equal to 3 mm in subjects of different age groups. The data suggested that in younger subject groups, progression was confined to a subset of individuals, while in older age groups, more subjects and sites became involved. A major feature of destructive periodontal disease in older individuals was the accompaniment of attachment loss with recession at the gingival margin. Deep pockets were relatively infrequently detected, while advanced loss of attachment (with recession) occurred at many sites.
本研究描述了从日本铫子市随机选取的319名年龄在20至79岁之间的受试者的牙周袋探诊深度、探诊附着水平和牙龈退缩数据。研究结果以单根牙（切牙、尖牙、前磨牙）和磨牙颊面、邻面和舌面这三个参数的平均值、频率分布和百分位数图的形式呈现。对探诊牙周袋深度和探诊附着水平的检查者间以及检查者内误差进行了评估，发现误差较小。报告的数据显示，几乎所有研究对象的牙列中都有一个或多个部位受到破坏性牙周疾病的影响，且疾病的严重程度随年龄增长而增加。进一步观察发现，在每个年龄组中，磨牙的附着丧失比单根牙更多，而且邻面通常比相应的颊面和舌面失去更多的牙周组织支持。然而，在给定牙齿或一组牙齿的不同表面之间观察到的附着丧失差异相对较小。在20至59岁的年龄组中，在一小部分受试者样本中发现了晚期破坏性牙周疾病，而在60岁以后，广泛的破坏性牙周炎很常见。通过比较不同年龄组受试者中附着丧失大于或等于3mm部位的频率分布，试图研究破坏性疾病随年龄的进展情况。数据表明，在较年轻的受试者组中，进展仅限于一部分个体，而在较年长的年龄组中，更多的受试者和部位受到影响。老年个体破坏性牙周疾病的一个主要特征是附着丧失伴随着牙龈边缘的退缩。较深的牙周袋相对较少被检测到，而在许多部位出现了严重的附着丧失（伴有退缩）。
