The purpose of the present study was to assess by radiographic means the pattern of destructive periodontal disease within the dentition of individuals of different ages. Full-mouth series of intra-oral radiographs from 531 dentate individuals aged 25-75 years were examined with respect to number and type of remaining teeth, location of the alveolar bone in relation to the cemento-enamel junction and presence of angular bony defects. The assessments of alveolar bone levels and angular bony defects were performed at the approximal surfaces of all teeth present. The results showed that although most individuals had experienced a reduction in alveolar bone height with age, only a small number of subjects had developed advanced breakdown of the periodontium. Hence, pronounced bone loss was observed in only 11% of the subjects and was non-existent in ages below 35 years. 23% of the individuals accounted for 3/4 of the total number of sites with bone level values (bone loss) of greater than or equal to 6 mm. Out of the total number of tooth sites examined, 28% showed no bone loss, while 13% demonstrated pronounced periodontal tissue breakdown. Angular bony defects were found at 8% of all teeth examined and were most frequent at the maxillary first premolars. Teeth in the incisor regions consistently showed the highest frequency of advanced alveolar bone loss and the lowest frequency of normal tissue support, while corresponding figures for teeth in the molar regions were found to be the opposite. However, molars were the most frequently missing teeth.
本研究的目的是通过影像学手段评估不同年龄个体牙列中破坏性牙周疾病的模式。对531名年龄在25至75岁之间的有牙个体的全口口腔内X光片进行了检查，内容包括剩余牙齿的数量和类型、牙槽骨相对于牙骨质-釉质界的位置以及角形骨缺损的存在情况。在所有现存牙齿的邻面进行牙槽骨水平和角形骨缺损的评估。结果显示，尽管大多数个体的牙槽骨高度随年龄增长而降低，但只有少数受试者出现了牙周组织的严重破坏。因此，仅11%的受试者观察到明显的骨质流失，且在35岁以下的人群中不存在。23%的个体占骨水平值（骨质流失）大于或等于6毫米的部位总数的3/4。在所检查的牙齿部位总数中，28%没有骨质流失，而13%表现出明显的牙周组织破坏。在所有检查的牙齿中，8%发现有角形骨缺损，在上颌第一前磨牙处最为常见。切牙区的牙齿始终显示出牙槽骨严重流失的最高频率和正常组织支持的最低频率，而磨牙区牙齿的相应数据则相反。然而，磨牙是最常缺失的牙齿。
