[目的]了解山东省中老年城乡人群牙周病的流行现状,为山东省牙周病的防治提供资料支持。[方法]2005年9月,采用多阶段分层等容量随机抽样方法,在山东省抽取的35~44岁(中年组)、65~74岁(老年组)城乡常住人口合计1 578人,调查牙周探诊深度(PPD)和附着丧失(LOA)。[结果]调查中年组790人,老年组788人。浅、深牙周袋检出率,中年组分别为39.24%、4.68%,老年组分别为56.60%、11.80%(P<0.01);男性分别为53.48%、9.86%,女性分别为42.31%、6.61%(P<0.01、P<0.05)。附着丧失4~5 mm、6~8 mm、9~11 mm、≥12 mm的检出率,中年组分别为33.54%、8.86%、1.65%、0.38%,老年组分别为71.45%、35.91%、11.68%、2.66%(P<0.01)。附着丧失≥4 mm的检出率,老年组为57.74%,中年组为39.49%(P<0.01);男性为53.98%,女性为43.20%(P<0.01)。[结论]山东省中老年牙周袋及附着丧失情况比较严重。
[Objective] To understand the prevalence of periodontal disease in middle-aged and elderly urban and rural residents in Shandong Province and provide data support for the prevention and treatment of periodontal disease in Shandong Province. [Methods] In September 2005, a total of 1 578 urban and rural permanent residents aged 35-44 (middle-aged) and 65-74 (elderly) population were collected in Shandong Province using multi-stage stratified and equal-capacity random sampling method. Periodontal exploration depth (PPD) and attachment loss (LOA) were investigated. [Results] 790 middle-aged and 788 elderly patients were investigated. The detection rate of shallow and deep periodontal pockets were 39.24% and 4.68% in the middle-aged group and 56.60% and 11.80% in the elderly group (P <0.01), respectively, with 53.48% and 9.86% for males and 42.31% for females, respectively , 6.61% (P <0.01, P <0.05). The detection rate of 4 to 5 mm, 6 to 8 mm, 9 to 11 mm and ≥ 12 mm in the middle-aged group was 33.54%, 8.86%, 1.65% and 0.38% respectively in the middle-aged group and 71.45% and 35.91 %, 11.68%, 2.66% (P <0.01). The detection rate of attachment loss ≥ 4 mm was 57.74% in the elderly group and 39.49% in the middle age group (P <0.01), 53.98% for males and 43.20% for females (P <0.01). [Conclusion] The elderly patients with periodontal pocket and attachment loss in Shandong Province are more serious.
