Relation between oral health and nutritional condition in the elderly

Oral health is a prerequisite for a good chewing function, which may have an impact on food choices and nutritional well-being. OBJECTIVE: This study was designed to evaluate the relationship between oral health status and nutritional status in the elderly. MATERIAL AND METHODS: In this cross-sectional study, 33 elderly people from the Group for the Elderly Interdisciplinary Geriatrics and Gerontology Program, at Fluminense Federal University, Niteroi, RJ, Brazil, completed a questionnaire to collect information on socioeconomic status, eating habits, physical activity and health habits, undertook a clinical oral examination, blood test, and anthropometric measurements, and were allocated into groups according to age. The oral health status was assessed using the index for decayed, missing and filled teeth (DMFT). The nutritional status was assessed using hemoglobin, hematocrit and albumin concentrations in blood, anthropometric values and the body mass index. RESULTS: Tooth loss was the biggest nuisance to the elderly subjects (57.6%), followed by the use of dentures (30.3%) and ill-fitting dentures (33.3%). 66.6% of patients had difficulty in chewing, and 54.5% reported this to be due to prostheses and 13.6% to the absence of teeth. A significant correlation was found between DMFT and the value of suprailiac skinfold thickness (rho=0.380, p=0.029). CONCLUSION: The results support the temporal association between tooth loss and detrimental changes in anthropometry, which could contribute to increased risk of developing chronic diseases

Stress, cortisol, and periodontitis in a population aged 50 years and over

Periodontitis and its relationship with psychoneuro-immunological variables, such as psychological stress and cortisol, have been little explored. The objective of this study was to evaluate the extent and severity of chronic periodontitis and its association with the levels of salivary cortisol and the scores obtained with a stress questionnaire in a population aged 50 years and over. We studied 235 individuals in a cross-sectional study. They answered the Lipp's Inventory of Stress Symptoms for Adults, were instructed to collect three saliva samples for cortisol analysis, and were examined for evaluation for periodontitis. Based on logistic regression, cortisol levels were positively associated with the following outcomes: means of clinical attachment level (CAL) > = 4 mm [ OR = 5.1, 95% CI (1.2, 20.7)]; 30% of sites with CAL > = 5 mm [ OR = 6.9, 95% CI ( 1.7, 27.1)]; and 26% of sites with probing depth > = 4 mm [ OR = 10.7, 95% CI ( 1.9, 54.1)] after adjustment for confounding variables. The results suggest that cortisol levels were positively associated with the extent and severity of periodontitis.85432432

Hand function and oral hygiene in older institutionalized Brazilians

OBJECTIVES: To evaluate whether the oral hygiene of institutionalized older people differs significantly between groups of participants with different degrees of hand function. DESIGN: Cross-sectional study. SETTING: Residents of a long-term institution of Porto Alegre, Brazil. PARTICIPATION: Forty-nine institutionalized older people. Subjects restricted to bed or with Mini-Mental State Examination (MMSE) scores less than 15 were excluded. MEASUREMETS: Dental (Silness and Loe Index) and denture plaque (Modified Ambjornsen Plaque Index) scores were assessed as a measure of oral hygiene. Hand functions were assessed using the Jebsen-Taylor and the Purdue pegboard tests. Participants were grouped according to their levels of hand function (regarded as good if test values were at the median or higher in the case of Purdue pegboard test and below the median in the case of Jebsen-Taylor test). Existence of differences between groups was checked using univariate analysis of variance, adjusting for age, sex and cognitive status according to MMSE. RESULTS: Dentate participants with poor hand function according to the Dominant Hand Purdue test harbored significantly more dental plaque after adjustment for age, sex, and cognitive status. Complete denture wearers with poor hand function according to the Dominant Hand and Sum of Three Steps Purdue tests and the total Jebsen-Taylor test also had significantly more denture plaque after adjustment. CONCLUSIONS: The results support the notion that hand function plays a central role in oral hygiene, mainly removal of dental and denture plaque, in institutionalized older people.5591333133

Oral status and its association with obesity in Southern Brazilian older people

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)The loss of a functional dentition imposes eating difficulties and food avoidance, which may be detrimental in terms of nutritional status and health. The objective of this study was to investigate whether tooth loss and edentulism that were not rehabilitated with dental prostheses were associated with obesity among elderly in Southern Brazil. A random sample of 872 independently living elderly was evaluated by means of a cross-sectional study. Socio-demographic, medical history and behaviour data were assessed using a standardised questionnaire. Two trained dentists assessed the number of teeth and use of prostheses in accordance with the WHO criteria. Height and weight were assessed and used to generate body mass index (BMI = weight (kilos)/height (cm)(2)) data. Participants were categorised into non-obese (BMI 30). Multivariate logistic regression was used to model the relationship between number of teeth and use of dental prostheses with obesity adjusting for confounders. Multivariate logistic regression revealed that edentulous persons wearing only upper dentures (OR = 2.34, 95% CI 1.18-4.27) and dentate participants with one to eight teeth wearing 0-to-1 prosthesis (OR = 2.96, 95% CI 1.68-5.19) were more likely to be obese. The results show that a poorer oral status, represented by having fewer teeth that were not replaced by dental prostheses, was associated with obesity in Southern Brazil older people, suggesting a close relationship between poor oral status and systemic conditions that may have important clinical implications.2614652Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Oral health behaviour and socio-demographic profile of subjects with Alzheimer's disease as reported by their family caregivers

Objective: To evaluate the oral health care provided to subjects with Alzheimer's disease (AD) as reported by their family caregivers. Method: Structured interviews were performed with 56 Alzheimer caregivers from the Group of relatives and friends of subjects with AD of the Hospital de Clinicas de Porto Alegre. Spearman and Pearson correlations were performed. Results: The mean age of the subjects with AD was 76.09 (+/- 7.76) years, 53.6% were female and 58.9% were in the advanced stage of AD. The mean number of teeth present was 11.66 (+/- 10.94), and oral hygiene was performed 2.21 (+/- 1.04) times/day. The provision of oral health care to subjects with AD was carried out by caregivers in 85.7%. Oral hygiene was provided by the caregivers to the subjects with AD with the aid of a toothbrush and/or gauze embedded with non-fluoridated mouthwash in the majority of the cases. Complete dental prostheses were cleaned with the aid of mouthwashes instead of denture brushes by 44% of the subjects/caregivers. There was a significant association between the number of teeth in the subjects with AD and the number of oral hygiene procedures performed per day and current smoking. Conclusion: Oral health care planning for subjects with AD should take into account caregivers' perceptions and knowledge about oral health and hygiene as caregivers represent the primary providers to these patients when the disease progresses from early to more advanced stages.241364
