Metabolic Syndrome Parameters in adolescents may be determinants for the future periodontal diseases

AIM The prevalence of metabolic syndrome (MetS) increases even in adolescents. The evidence that MetS is associated with the periodontal diseases in adolescents has been understudied. Therefore, our aim was to assess the association between MetS parameters and gingivitis in adolescents. MATERIAL AND METHODS A total of 941 participants (590 boys, 351 girls), aged 12-18 years was selected from the Fourth Korea National Health and Nutrition Examination Survey, a cross-sectional and nationally representative survey, which had had information on waist circumference, blood pressure, serum triglyceride, high-density lipoprotein (HDL) cholesterol, and the fasting blood sugar and community periodontal Index (CPI). RESULTS The number of positive parameters of MetS showed significant positive correlation with gingivitis; adjusted and crude ORs with one positive parameters of MetS were 1.92 (95% CI: 1.21-3.04) and 1.88(95% CI: 1.28-2.76), respectively. And adjusted OR with three or more positive parameters of MetS was 3.29 (95% CI: 1.24-8.71). Among five parameters of MetS, Low HDL-cholesterol showed significant association with gingivitis (crude OR 2.12, 95% CI 1.20-3.73; adjusted OR 1.96, 95% CI 1.24-3.12). CONCLUSIONS Having more positive parameters of MetS and low HDL-cholesterol parameter had an independent relationship with the prevalence of gingivitis, which may be determinants for the future periodontal diseases even in adolescents.

Relationship between chewing ability and cognitive impairment in the rural elderly

OBJECTIVE Relationship between masticatory function and cognitive impairment had been suggested but still understudied. We investigated the association between chewing ability and cognitive impairment among the elderly living in a rural region. METHODS A total of 295 elderly individuals aged ≥70 years in a rural city of Korea participated in a cross-sectional study. Trained nurses conducted interviews and assessed chewing ability using gum that changed color based on chewing performance. Cognitive impairment was assessed using the Mini-Mental State Examination for Dementia Screening (MMSE-DS) of Korean vesrsion. Socio-demographic characteristics, activities of daily living (ADL), Mini-Nutritional Assessment (MNA) were also assessed using questionnaires as potential confounders. RESULTS The mean age of the participants was 81.4 (ranged 70-102) years and 67.8% of them were female. Participants with low chewing ability were significantly older, dependent, and had lower MNA and MMSE-DS scores. The elderly with middle or low chewing ability had significantly higher risk for having cognitive impairment than those with higher chewing ability. CONCLUSION Our findings suggest that poor chewing ability is associated with cognitive impairment or dementia in the elderly living in rural area.

Social Capital and Oral Health: the association of social capital with edentulism and chewing ability in the rural elderly

OBJECTIVE The association between social capital and oral health had been reported in various ways, but still remains unclear. We investigated the association between the social capital of the elderly living in a rural region and their edentulism and chewing ability. METHODS A total of 241 elderly aged≥70years living in a rural city of Korea participated in this cross-sectional study. Their social capital was surveyed by questionnaire assessing its network and trust dimensions. Their edentulism and chewing ability were assessed by oral examination and chewing gum whose color changes based on the mastication performance. RESULTS The mean age of the participants was 82.7 (ranged 71 to 101) years and 68.8% of them were female. In the binomial regression analysis, the general network aspect of the network dimension was significantly associated with chewing ability, of which the prevalence ratio was 1.88 (95% CI: 1.16-3.06) in the age, sex, education and marital status-adjusted model. CONCLUSION Our findings suggest that social capital, such as a poor social network, is associated with poor chewing ability in the elderly living in rural areas.

Relationship between the activities of daily living, oral health-related quality of life and dementia: ADL and OHRQoL and dementia

The aim of the present study was to investigate the association between the activities of daily living and the oral health‐related quality of life and dementia in older adults.

Lasting effect of an oral hygiene care program for patients with stroke during in-hospital rehabilitation: a randomized single-center clinical trial

Abstract Purpose: Because the oral hygiene is poorly prioritized in the immediate post-stroke period, we implemented an oral hygiene care program (OHCP) for stroke in-patients and evaluated its persistence after discharge. Method: In all, 62 patients with stroke who were admitted to the rehabilitation ward were randomly assigned to two groups: 33 patients to the intervention group and 29 to the control group. The OHCP, including tooth brushing education and professional tooth cleaning, was administered to the intervention group twice a week six times during in-hospital rehabilitation. Oral health status was examined both at baseline and three months after discharge from the hospital. Oral hygiene status was examined at three- to four-day intervals five times during the hospitalization period. Results: After OHCP, oral hygiene status including the plaque index, calculus index, and O’Leary plaque index improved significantly in the intervention group, compared to the control group (p < 0.05). In the intervention group, after administration of the OHCP for the fourth time, the O’Leary index improved significantly, and remained high when checked three months after discharge (p < 0.001). Conclusions: An OHCP conducted during in-hospital rehabilitation was effective in improving oral health and plaque control performance among patients with stroke, with effects still seen three months after discharge from the hospital. Implications for Rehabilitation Initial oral hygiene status and plaque control performance were poor in stroke patients who were in rehabilitation center. An oral hygiene care program during in-hospital rehabilitation was effective in improving oral hygiene status and plaque control performance among stroke patients at three months after discharge. Repeated tooth brushing education and professional tooth cleaning were necessary to improve plaque control performance of stroke patients.
