To assess the extent of remission and progression of periodontal diseases among adults in a Northeast German Region.
The Study of Health in Pomerania (SHIP) is a population-based cohort study with baseline examinations conducted in 1997-2001 and 5-year-follow-up in 2002-2006. The study comprised 2558 subjects aged 20-81 years. Periodontal status was assessed by probing depth (PD) and attachment level (AL), measured at four surfaces per tooth, half-mouth. An event was defined as AL progression or remission of ≥3 mm on ≥2 sites.
Average change in mean AL (mean PD) was 0.10 mm (-0.05 mm) during follow-up, equalling 0.02 mm/year (-0.01 mm/year). Adjusted for gender and follow-up time, change in mean AL was significantly higher in 20-29- and 60-69-year-old patients compared with 50-59-year-old patients (p < 0.05). 6.5 (7.5) events of progression (remission) in AL per 100 person-years were observed. In multivariate models, risk factors for progression comprised current smoking, middle or low education, being single or divorced and diabetes (p < 0.05). Enhanced progressive attachment loss seen in 20-29- and 60-81-year-old patients was explained through unfavourable risk factors distributions.
Periodontal progression was moderate. Periodontal prophylaxis and motivation to reduce risk factors should especially be addressed to patients having unfavourable risk factor distributions.
评估德国东北部地区成年人牙周病的缓解和进展程度。
波罗的海健康研究（SHIP）是一项基于人群的队列研究，基线检查于 1997-2001 年进行，随访时间为 5 年，于 2002-2006 年进行。该研究共纳入 2558 名年龄在 20-81 岁的受试者。牙周状况通过探诊深度（PD）和附着丧失（AL）进行评估，每颗牙的四个表面，半口进行测量。事件定义为至少两个部位的 AL 进展或缓解≥3mm。
随访期间平均 AL（平均 PD）平均变化为 0.10mm（-0.05mm），相当于每年 0.02mm（-0.01mm/年）。调整性别和随访时间后，20-29 岁和 60-69 岁患者的平均 AL 变化明显高于 50-59 岁患者（p<0.05）。每 100 人年观察到 AL 进展（缓解）事件 6.5（7.5）次。在多变量模型中，进展的危险因素包括当前吸烟、中等或低教育程度、单身或离异以及糖尿病（p<0.05）。20-29 岁和 60-81 岁患者中观察到的牙周附着丧失进展增强，这可以通过不利的危险因素分布来解释。
牙周病进展程度中等。牙周病预防和降低危险因素的动机应特别针对具有不利危险因素分布的患者。
