目的:分析预测成年男女下颌皮质宽度(MCW)和下颌皮质指数(MCI)的因素。
方法:使用来自Tromsø研究的427名女性和335名40-84岁男性的数据:Tromsø7。T-score,年龄,绝经状态(女性),剩下的牙齿,在线性和logistic回归分析中分析了牙周状况,分别作为MCW和MCI的预测因子。
结果:T分数,年龄,剩余牙齿的数量显着预测了女性而不是男性的MCW。标准化β系数分别为0.286、-0.231和0.131。线性回归模型解释了24%的女性MCW变异。通过T评分显着预测女性的MCI,年龄,其余牙齿的Wald值分别为9.65、6.17和5.83。逻辑回归模型解释了女性MCI变异的16.3-23%。在男性中,T评分是皮质侵蚀的唯一重要预测指标,逻辑模型仅解释了MCI变异的4.3-5.8%。
结论:在女性中,T评分与MCW和MCI的关系比其他因素更强,这支持了这些指标对骨质疏松症筛查的有用性。相反,T评分与MCW无关,仍然是男性MCI的唯一重要预测因子,但程度低于女性。
结论:了解影响下颌皮质形态的因素对于进一步研究MCW和MCI对女性和男性骨质疏松筛查的有用性至关重要。
OBJECTIVE: To analyze factors predicting mandibular cortical width (MCW) and mandibular cortical index (MCI) in adult females and males.
METHODS: Data on 427 females and 335 males aged 40-84 from The Tromsø study: Tromsø7 were used. T-score, age, menopausal status (for females), remaining teeth, and periodontal status were analyzed in linear and logistic regression analyses as predictors of MCW and MCI, respectively.
RESULTS: T-score, age, and the number of remaining teeth significantly predicted MCW in females but not males. Standardized β coefficients were 0.286, -0.231, and 0.131, respectively. The linear regression model explained 24% of MCW variation in females. MCI in females was significantly predicted by T-score, age, and remaining teeth with the Wald values of 9.65, 6.17, and 5.83, respectively. The logistic regression model explained 16.3-23% of the variation in MCI in females. In males, T-score was the only significant predictor of the eroded cortex, and the logistic model explained only 4.3-5.8% of the variation in MCI.
CONCLUSIONS: The T-score demonstrated a stronger relationship with MCW and MCI than other factors in females, which supports the usefulness of those indices for osteoporosis screening. Conversely, the T-score exhibited no association with MCW and remained the only significant predictor of MCI in males, yet to a lesser extent than in females.
CONCLUSIONS: Understanding factors affecting mandibular cortical morphology is essential for further investigations of MCW and MCI usefulness for osteoporosis screening in females and males.
