Abstract
Objectives: This study aimed to assess the association between posterior occlusal support (POS) and the risk of tooth loss in older adults aged ≥75 years. Methods: This longitudinal study analyzed 94,422 participants who participated in multiple dental check-ups provided as part of the public healthcare services in Osaka, Japan, from 2018 to 2022. The participants were categorized into nine groups (A1–3, B1–4, and C1 and C2) according to their POS status using the Eichner index at baseline. The dental charts were compared between the initial and final assessments to assess tooth loss. Logistic regression analysis was used to examine the association between POS status and tooth loss, adjusted for several covariates, including age, sex, body mass index, periodontal status, oral hygiene, history of diabetes, history of hypertension, attendance at the annual dental check-up, and observational period. Furthermore, stratified logistic regression analyses were conducted using anterior or posterior tooth loss. Results: After controlling for confounders, POS status was associated with tooth loss. The odds ratios (ORs) with A1 as the reference were 1.74 in A2, 2.55 in A3, 3.40 in B1, 4.74 in B2, 5.79 in B3, 6.00 in B4, 4.44 in C1, and 3.00 in C2, respectively. The ORs for anterior tooth loss were higher than those for posterior tooth loss, with the highest OR observed in B4 (21.4). Conclusions: This large population-based cohort study showed that a decreased POS was a risk indicator for tooth loss; furthermore, the risk increased even further in the anterior teeth region.
