Background:
This study aimed to examine the association between oral health-related quality of life and probable sarcopenia in community-dwelling older adults, and to evaluate the potential role of oral health assessment in routine geriatric care.
Methods:
This cross-sectional study included 315 individuals aged ≥65 years who were registered with the Home Health Unit and the Geriatric Outpatient Clinic of a tertiary hospital in Türkiye. Oral health-related quality of life was measured using the Geriatric Oral Health Assessment Index (GOHAI). Muscle strength was assessed with a handgrip dynamometer, and probable sarcopenia was defined according to the revised European Working Group on Sarcopenia in Older People (EWGSOP2) criteria as low muscle strength. Additional assessments included the Mini Nutritional Assessment-Short Form (MNA-SF), Strength, Assistance with walking, Rise from a chair, Climb stairs, and Falls (SARC-F) questionnaire, Clinical Frailty Scale (CFS), Katz Index of Independence in Activities of Daily Living, and Mini-Cog test. Correlation, logistic regression, and receiver operating characteristic (ROC) analyses were performed.
Results:
Participants had a mean age of 80.8 years (SD 7.5); 43.5% were male. Handgrip strength was positively correlated with GOHAI (r = 0.376, p <0.001), MNA-SF (r = 0.446, p <0.001), and Mini-Cog (r = 0.126, p <0.05), and negatively correlated with age, SARC-F, and frailty. GOHAI correlated positively with MNA-SF (r = 0.206, p <0.01) and negatively with SARC-F (r = -0.134, p <0.05). In univariate logistic regression, lower GOHAI, lower MNA-SF, older age, polypharmacy, and higher SARC-F scores were significantly associated with probable sarcopenia. In multivariate analysis, GOHAI, MNA-SF and polypharmacy remained independent predictors.
Conclusion:
Poor oral health-related quality of life was independently associated with probable sarcopenia in older adults. Incorporating an oral health measure such as the GOHAI into routine geriatric assessment may facilitate early detection of at-risk individuals and support timely, targeted interventions.

01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
