“…As for denture status, the MMSE-DS score of unnecessary subjects was higher than those who needed dentures (ß = 0.036, p = 0.005), and in occlusal balance, the subjects with better posterior occlusion than anterior occlusion showed higher MMSE-DS score (ß = 0.113, p = 0.006). The results also demonstrated similar patterns as differences in another study about better the dentures were and more occlusion force of posterior teeth with better cognitive ability [ 36 , 37 , 39 ].…”

Age-related decline in cognitive function is a major challenge in geriatric healthcare. A possible explanation is that the tooth loss or low chewing ability is at cause of cognitive impairment or dementia. The study aimed to investigate the potential relationship between chewing ability and cognitive function in the elderly. A total of 563 participants aged 65 years or over residing in urban and rural areas of South Korea were surveyed. The chewing ability was measured by objectively measurable indications such as the number of remaining teeth, denture status, color-changeable gum, and occlusal balance using T-Scan III®. The cognitive function was measured by the Korean version of Mini-Mental State Examination-Dementia Screening (MMSE-DS) and a score of 24 or more (out of 30) indicates a normal cognition, below 23 indicates cognitive impairment. The association between socio-demographic factors, chewing ability factors, and cognitive function demonstrated statistically significant results. When comparing the denture status and chewing ability, the proportion of need denture group had fewer remaining teeth and anterior balanced occlusion. The average number of remaining teeth in anterior balanced occlusion with cognitive impairment was 11.2 compared to posterior balanced occlusion with the normal cognition 19.2. A multiple linear regression analysis declared a significant correlation between number of remaining teeth, denture status, occlusal balance, and cognitive function. Results of the present study revealed objectively measurable indications are suitable for chewing ability assessment and correlated with cognitive function.

The purpose of this study was to evaluate the association between metabolic syndrome and the number of present teeth in a Korean adult population. Methods: We analyzed the effect of the components of metabolic syndrome in adults aged older than 45 years on the number of present teeth using raw data from the 6th National Health and Nutrition Survey (2013-2015). For the data analysis, complex samples multivariable logistic regression analysis was performed by correcting the disturbance variables as demographic and socioeconomic variables (gender, age, education level, household income, residential area, family type, and economic activity) and oral health-related behavioral variables (smoking, alcohol consumption, tooth brushing frequency, interdental tooth brushing, flossing, and dental checkups). Results: On analyzing the association between the effects of metabolic syndrome components on less than 20 present teeth by adjusting for demographic and socioeconomic variables and correcting for both general characteristics and oral health-related behavioral variables, the risk of having less than 20 present teeth was 1.25 times (95% confidence interval 1.08-1.46) higher in the high fasting glucose group compared to that in the non-high fasting glucose group. Metabolic syndrome composed of three or more components was significantly associated with less than 20 present teeth. Conclusions: It is necessary to continuously educate Korean adults about oral health behavior. Appropriate interventional programs to prevent oral disease should be provided when patients with metabolic syndrome visit dental clinics and public health centers.
