This study determines tooth loss rate over a 10-year period and identifies predictors of tooth loss in two separate US adult longitudinal study populations.
Subjects from the Baltimore Longitudinal Study of Aging (BLSA), consisting of 47 men and 47 women, ages ranging from 30 to 69 years, were compared to subjects from the VA Dental Longitudinal Study (VADLS) in Boston, MA, consisting of 481 men in the same age range. Baseline and follow-up examinations were performed on each cohort over a 10-year period. Using multivariate regression models, significant predictors of tooth loss were identified.
A mean rate of tooth loss of 1.5 teeth lost per 10 years was noted in the VADLS cohort compared to 0.6 teeth lost per 10 years in the BLSA (P < .001). Combining subjects from both populations, significant predictors of tooth loss were baseline values of: percent of teeth with restorations, mean probing pocket depth score, age, tobacco use, alcohol consumption, number of teeth present, and male sex. However, the set of significant predictor variables differed between the two populations and sexes. In BLSA men, number of teeth present, percent of teeth with restorations, mean probing pocket depth score, and alcohol consumption, but not age, were significant, while in BLSA women, only age was a significant predictor.
Over a 10-year period, the incidence of tooth loss, the rates of tooth loss, and the predictors of tooth loss were found to vary by population and by sex. These results illustrate the limits of generalizing tooth loss findings across different study cohorts and indicate that there may exist important differences in risk factors for tooth loss among US adult populations.
本研究确定了10年期间的牙齿脱落率，并在两个不同的美国成年纵向研究人群中识别出牙齿脱落的预测因素。
将巴尔的摩衰老纵向研究（BLSA）中的受试者（47名男性和47名女性，年龄在30至69岁之间）与马萨诸塞州波士顿的退伍军人事务部牙科纵向研究（VADLS）中的受试者（481名同年龄段男性）进行比较。在10年期间对每个队列进行了基线和随访检查。使用多变量回归模型，确定了牙齿脱落的显著预测因素。
VADLS队列中每10年牙齿脱落的平均率为1.5颗，而BLSA中为每10年0.6颗（P <.001）。将两个群体的受试者合并后，牙齿脱落的显著预测因素为以下基线值：有修复体的牙齿百分比、平均探诊袋深度评分、年龄、吸烟、饮酒、现存牙齿数量和男性性别。然而，两个群体和不同性别之间的显著预测变量集有所不同。在BLSA男性中，现存牙齿数量、有修复体的牙齿百分比、平均探诊袋深度评分和饮酒是显著因素，但年龄不是，而在BLSA女性中，只有年龄是显著预测因素。
在10年期间，发现牙齿脱落的发生率、牙齿脱落率以及牙齿脱落的预测因素因群体和性别而异。这些结果说明了在不同研究队列中推广牙齿脱落研究结果的局限性，并表明美国成年人群体中牙齿脱落的风险因素可能存在重要差异。
