The purpose of this case-control study is to investigate the periodontal conditions in elderly men with and without osteoporosis or osteopenia and to determine their possible association with periodontal destruction.
A total of 200 community-dwelling Chinese males (age range: 69 to 78 years; mean ± SD age: 71.9 ± 3.3 years) were recruited from the Jockey Club Center for Osteoporosis Care and Control, The Chinese University of Hong Kong, including 67 subjects with osteoporosis, 66 subjects with osteopenia, and 67 age-matched normal control subjects based on bone mineral density at the hip, spine, and whole body measured by dual-energy x-ray densitometry. All subjects were interviewed using questionnaires and received a full-mouth periodontal examination.
Subjects with osteoporosis exhibited a significantly higher percentage of sites with clinical attachment loss (AL) > or= 6 mm compared to subjects with osteopenia (P <0.05); subjects with osteoporosis also showed a greater percentage of sites with interproximal gingival recession (GR) > or = 5 mm than did control subjects (P <0.05) after excluding smokers. Subjects with osteoporosis were more likely (odds ratio = 3.3; P <0.05) to exhibit interproximal GR > or = 5 mm than were control subjects. Osteoporosis remained significantly associated with severe clinical AL and interproximal GR after adjusting for age, supragingival plaque, and number of teeth lost.
This study suggests that osteoporosis is associated with severe clinical AL and interproximal GR in elderly Chinese men.
本病例对照研究旨在探讨伴有或不伴有骨质疏松症或骨量减少症的老年男性的牙周状况，并确定其与牙周破坏的可能相关性。
共招募了 200 名居住在社区的中国男性（年龄范围：69 至 78 岁；平均年龄 ± 标准差年龄：71.9 ± 3.3 岁），他们来自香港中文大学赛马会骨质疏松症护理及控制中心，根据双能 X 射线骨密度仪测量的髋部、脊柱和全身骨密度，将 67 名骨质疏松症患者、66 名骨量减少症患者和 67 名年龄匹配的正常对照组患者分为三组。所有患者均通过问卷调查进行访谈，并接受全口牙周检查。
与骨量减少症患者相比，骨质疏松症患者的临床附着丧失（AL）>或= 6 毫米的位点比例明显更高（P <0.05）；在排除吸烟者后，骨质疏松症患者的近中牙龈退缩（GR）>或= 5 毫米的位点比例也高于对照组（P <0.05）。与对照组相比，骨质疏松症患者发生近中 GR >或= 5 毫米的可能性更高（比值比= 3.3；P <0.05）。在调整年龄、龈上菌斑和失牙数后，骨质疏松症与严重的临床 AL 和近中 GR 仍显著相关。
本研究表明，骨质疏松症与老年中国男性严重的临床 AL 和近中 GR 相关。
