This study aimed to provide oral epidemiological data describing periodontal destruction among older adults in South Australia. A cross-sectional survey design was employed and periodontal assessments were made among 801 persons aged 6+ drawn at random from the non-institutionalized population. Measurements of pocket depth (PD) and gingival recession (GR) were made at three sites on all teeth and used to compute loss of attachment (LOA). An average of 17 teeth per person were measured. LOA of 4+ mm at one or more sites was observed among 89.1% of persons. A mean of 78.1% of sites per person had LOA of 2+ mm (extent) and the mean LOA at sites with LOA of 2+ mm was 3.09 mm (severity). Extent and severity were greater for males and for persons aged 80+ years. Extent was virtually identical for mesio-buccal and disto-lingual sites, while severity was virtually identical for mid-buccal and disto-lingual sites. Patterns of GR and PD varied according to the jaw and type of tooth. Maxillary first and second molars had the greatest mean LOA, and the majority of LOA in the maxilla was due to PD. In the mandible there was less variation in LOA among anterior and posterior teeth, and LOA tended to be more equally divided between GR and PD. Levels of periodontal destruction of South Australia were broadly similar to results from North American studies of older adults which have used full-mouth periodontal assessments.
本研究旨在提供口腔流行病学数据，描述南澳大利亚州老年人的牙周破坏情况。采用横断面调查设计，对从非机构化人群中随机抽取的801名6岁及以上的人员进行牙周评估。在所有牙齿的三个部位测量牙周袋深度（PD）和牙龈退缩（GR），并用于计算附着丧失（LOA）。每人平均测量17颗牙齿。89.1%的人在一个或多个部位观察到附着丧失4毫米及以上。每人平均78.1%的部位有2毫米及以上的附着丧失（范围），在有2毫米及以上附着丧失的部位，平均附着丧失为3.09毫米（严重程度）。男性和80岁及以上人群的范围和严重程度更大。近中颊侧和远中舌侧部位的范围几乎相同，而颊侧中部和远中舌侧部位的严重程度几乎相同。牙龈退缩和牙周袋深度的模式因颌骨和牙齿类型而异。上颌第一和第二磨牙的平均附着丧失最大，上颌的大多数附着丧失是由牙周袋深度引起的。在下颌，前牙和后牙的附着丧失差异较小，附着丧失在牙龈退缩和牙周袋深度之间的分布往往更为均匀。南澳大利亚州的牙周破坏水平与北美对老年人进行全口牙周评估的研究结果大致相似。
