Researching the impact of oral health on diet and nutritional status: methodological issues

Sources and determinants of free sugars intake by 5-year-old Australian children in the SMILE cohort

Reducing free sugars intake is important for the prevention of dental caries and obesity in children. The study aimed to determine the amount and sources of free sugars known to contribute to dental caries, and identify sociodemographic determinants of intake by children aged 5 years in Australia. Cross-sectional analysis of dietary data from a cohort study, collected using a customized food frequency questionnaire were used to calculate free sugars intake as grams/day and percentage contribution to Estimated Energy Requirement (EER). The percent contribution of food sources to free sugars intake was derived. Sociodemographic determinants of achieving intakes within WHO thresholds (i.e., <5% and <10% Energy were explored with multinomial logistic regression. Complete data were available for 641 children (347 boys, 294 girls). Median (IQR) free sugars intake (g/day) was 31.6 (21.3-47.6) in boys and 28.1 (19.6-47.9) in girls. The median (IQR) percentage contribution to EER was 7.9 (5.4-12.7); 21% and 42% of children had intakes <5% EER and between 5% and <10%, respectively. The main sources of free sugars were: (1) Cakes, Biscuits and Cereal Bars; (2) Sweetened Milk Products (predominantly yoghurts) and (3) Desserts. Maternal university education, single-parent household, and maternal place of birth being Australia or New Zealand were associated with free sugars intake <5% EER. In conclusion, less than a quarter of 5-year-old children in the SMILE cohort achieved the WHO recommendations to limit free sugars to <5% EER. Strategies to lower free sugars intake could target priority populations such migrants, populations with lower levels of education or health literacy and identify areas for intervention in the wider food environments that children are exposed to.

The effect of food supplements on completely edentulous women rehabilitated with complete dentures: A randomized controlled trial

Aim

Neglected oral health is a major issue, especially in women of developing countries, leading to early loss of teeth which may further lead to malnutrition, degradation of overall health, and increased chances of osteoporosis. Thus, the aim of this study was to assess the effect of food supplement on masticatory performance, nutritional status, electromyography (EMG) (masseter and temporalis), and bone mineral density (BMD) among women rehabilitated with complete denture.

Settings and Design

Hospital based randomized controlled trial.

Materials and Methods

A randomized controlled trial with 106 women of 45-65 years rehabilitated with complete denture (56 received food supplement and 50 did not receive food supplement) and 52 healthy control was conducted. The outcomes were assessed at baseline and 3 and 6 months of follow up (after complete denture fabrication). Outcomes were measured via masticatory performance, nutritional status (hemoglobin, serum calcium, albumin, and Vitamin D level), EMG of masseter and temporalis muscles, and BMD.

Statistical Analysis Used

Friedman's analysis of variance test was used as a nonparametric test, and the Statistical Package for the Social Sciences version 21.0 at a significance level of 0.05 was used for statistical analysis.

Results

A statistically significant change was observed during follow up for the group with food supplement for BMD, EMG, and masticatory performance. When biochemical parameters were assessed during follow up, no statistically significant change was observed for both groups (with and without food supplement), except for serum calcium level in group which received food supplement.

Conclusion

It was found that the magnitude of effect was remarkably meager in food supplement group which could be perhaps due to less time given for follow up period. Longer duration of trials would yield better results.

Involvement of Oxidative Stress and Nutrition in the Anatomy of Orofacial Pain

Pain is a very important problem of our existence, and the attempt to understand it is one the oldest challenges in the history of medicine. In this review, we summarize what has been known about pain, its pathophysiology, and neuronal transmission. We focus on orofacial pain and its classification and features, knowing that is sometimes purely subjective and not well defined. We consider the physiology of orofacial pain, evaluating the findings on the main neurotransmitters; in particular, we describe the roles of glutamate as approximately 30-80% of total peripheric neurons associated with the trigeminal ganglia are glutamatergic. Moreover, we describe the important role of oxidative stress and its association with inflammation in the etiogenesis and modulation of pain in orofacial regions. We also explore the warning and protective function of orofacial pain and the possible action of antioxidant molecules, such as melatonin, and the potential influence of nutrition and diet on its pathophysiology. Hopefully, this will provide a solid background for future studies that would allow better treatment of noxious stimuli and for opening new avenues in the management of pain.

Implementation of a food science and nutrition module in a dental undergraduate curriculum

INTRODUCTION

To outline the development and implementation of a food science and nutrition module for dental undergraduate students that provides basic knowledge and clinical skills for improving oral health outcomes and understanding their importance for overall health.

MATERIALS AND METHODS

Interdisciplinary discussions with professionals with expertise in food science and nutrition, including dentists, dietitians and nutritionists, were held to agree on core subject areas in line with the evidence base. The module was delivered online to 2nd-year dental students due to COVID-19 restrictions. Students completed an online evaluation on completing the module. Final examination consisted of one essay question.

RESULTS

Subject areas and learning outcomes were derived from current and previous approaches to curriculum development. A total of 14 prerecorded lectures, including healthy eating guidelines, dietary assessment, specific oral effects of diet and food constituents were delivered and tutorials provided. The evaluation survey had a 90% (n = 39/43) response rate. A majority indicated that the course was "interesting," "worth doing" (59%) and "provided a good evidence base to understand nutrition and oral health" (87%). Nearly all students (92%) agreed that the course was "sufficiently structured to allow understanding of the key topics" and that "a good understanding of nutrition is important for a dentist" (95%).

CONCLUSION

A food science and nutrition module developed by a multidisciplinary team enabled dental students to gain an understanding of the role of diet in oral and overall health. The module facilitated the development of skills that enable students to utilise dietary assessment techniques and promote dietary interventions beneficial to oral health. The approach taken may act as a template for other institutions.

Establishing Healthy Eating 'Habits': A Pilot Randomised Controlled Trial of a Habit-Based Dietary Intervention following Oral Rehabilitation for Older Adults

An ageing population presents significant nutritional challenges, particularly for partially dentate adults. This two-armed pilot randomised controlled trial (RCT) compared habit formation (automaticity) for healthy eating behaviours between control and intervention groups after participation in a habit-based dietary intervention for older adults, following oral rehabilitation in the United Kingdom (UK). n = 54 participants were randomised to receive a habit-based dietary intervention (intervention group n = 27, IG) or standard dietary advice in a leaflet (control group n = 27, CG). The IG attended three sessions over six weeks, which focused on habit formation for three healthy eating behaviours (increasing fruit and vegetables, wholegrains, and healthy proteins). Participants were assessed for habit strength (using the Self-Report Behavioural Automaticity Index (SRBAI)) alongside health and nutrition outcomes at six weeks, four months and eight months. Forty-nine participants completed all follow-up visits. The IG compared to the CG had significant increases in automaticity at six weeks, four months (primary outcome) and eight months for eating ≥3 portions of fruit and vegetables; choosing wholegrain sources over white alternatives, and choosing healthy protein sources over red/processed meat. The mean change in the Mini Nutritional Assessment total score was greater in the IG compared with the CG at six weeks only (p = 0.03). A habit-based dietary intervention following oral rehabilitation increased automaticity for healthy dietary behaviours, which could translate into clinically meaningful benefits in this cohort of older adults.

Association of the number of natural teeth with dietary diversity and nutritional status in older adults: A cross-sectional study in China

AIM

To investigate the association of the number of natural teeth with overall dietary diversity and nutritional status in a nationally representative study among older adults in China.

MATERIALS AND METHODS

A cross-sectional analysis was conducted among community-dwelling adults aged 65 years or older from the Chinese Longitudinal Healthy Longevity Study. According to the self-reported number of natural teeth, participants were categorized into ≥20, 10-19, 1-9 natural teeth, and edentulous. Dietary diversity score (DDS) was constructed based on intake frequencies of 10 food groups assessed by a simplified food frequency questionnaire. The geriatric nutritional risk index was used to measure the malnutrition status (i.e., normal, mild malnutrition, and moderate-to-severe malnutrition) among a subgroup of participants. Linear and multinomial logistic regression models were used to examine the corresponding associations.

RESULTS

Among 54,796 study participants, the mean (SD) age was 87.86 (11.45) years, 82.7% had poor dentition (<20 natural teeth), and 27.3% wore dentures. After multivariable adjustment, participants with poor dentition had lower DDSs (β_edentulous  = -0.39, 95% confidence interval [CI], -0.48, -0.30; β_{1-9 teeth}  = -0.46, 95% CI, -0.55, -0.37; β_{10-19 teeth}  = -0.36, 95% CI, -0.46, -0.26) than those with 20 natural teeth or more. For individual food items, edentulous, 1-9 and 10-19 natural teeth were associated with lower odds of regular intake of fresh fruits, fresh vegetables, meat, fish and aquatic products, eggs, legumes, preserved vegetables, tea, and garlic, but higher odds of regular intake of sugar and sweets. Among participants with poor dentition, individuals without dentures had lower intake frequencies of most food groups than those wearing dentures. In addition, poor dentition was related to lower odds of normal nutritional status (odds ratio = 0.49, 95% CI, 0.27, 0.89).

CONCLUSIONS

Older adults with poor dentition had significantly lower dietary diversity and worse nutritional status. Future studies are warranted to identify effective interventions to improve the dietary quality and nutrition status among partially and fully edentulous individuals, including those with Stage IV periodontitis.

The association between oral health and nutritional status in older adults: a cross-sectional study

Objectives

This work aimed to describe the nutritional status of French older adults (age ≥ 90 years) and studied the association between oral health and nutritional status.

Methods

A cross-sectional study was carried out in 2014 among the participants of a cohort on cerebral and functional aging in France at their 25-year follow up (the PAQUID cohort). Nutritional status (Mini Nutritional Assessment [MNA]) and oral health status (number of decayed, missing, and filled teeth [DMFT], number of posterior occluding pairs, xerostomia [Xerostomia Inventory], and prosthetic rehabilitation) were recorded at the participants’ living places by two dentists. Univariate and multivariate logistic regressions were used to explore the association between oral health and nutritional status, with adjustments for potential confounders. Odds ratios (OR) were estimated with their 95% confidence interval (CI).

Results

87 participants were included in the analyses: 74.7% were females and the mean age was 94.1 years (± 3.0). Malnutrition or risk of malnutrition (MNA < 24) was present in 23 participants (26.4%), with only one having malnutrition. The mean DMFT score was 26.5 (± 5.3). The mean number of posterior occluding pairs was 1.5 (± 2.3). Twenty-one participants had xerostomia (24.1%). Only 8.1% of the participants had all their teeth or adequate dentures; 47.1% had inadequate dentures, while 44.8% had no dentures despite tooth loss. After adjustment, xerostomia (OR = 8.79; 95% CI = 2.38–39.10; p = 0.002) was found to be associated with malnutrition or risk of malnutrition.

Conclusion

Being at risk of malnutrition was common among people ≥ 90 years old and was associated with xerostomia. NCT04065828.

Associations between Dentition Status and Nutritional Status in Community-Dwelling Older Adults

BACKGROUND/OBJECTIVE

Older adults are at higher risk of malnutrition. The aim of this study was to explore associations between nutritional status and dentition status among older adults seeking care in a dental clinic.

METHODS

This was a cross-sectional study of data from older adults (65-89 y) who received care at a northeastern US urban dental school clinic between June 2015 and June 2020 (N = 305). Clinical and demographic data were obtained from the electronic health record; nutritional status was determined using the Self-Mini Nutritional Assessment (Self-MNA), and odontograms and digital radiography were used to determine dental data. Adjusted multivariable models were used to explore associations between variables.

RESULTS

The sample was 53.8% female with a median age of 72.0 y. The median Self-MNA score was 13, reflective of normal nutritional status; 29.5% were at risk of or had malnutrition. Median numbers of teeth and posterior and anterior occluding pairs of teeth (POP, AOP) were 18.0, 2.0, and 5.0, respectively. Those with normal nutritional status had significantly more teeth, POPs, and AOPs than those at risk of or with malnutrition (P = 0.015, P = 0.015, and P = 0.039, respectively). Every additional unit increase in the number of natural or restored teeth or POP was associated with significantly lower odds of being at risk of or with malnutrition (3% and 13%, respectively). Having functional dentition was associated with 46% lower odds of being at risk of or with malnutrition.

CONCLUSION

This study demonstrated that older adults who had more teeth, better occlusion, and functional dentition were more likely to be of normal nutritional status than those who had less teeth, had poorer occlusion, and lacked functional dentition. Further research with larger, more diverse samples and varied measures of dentition are needed to better understand the associations between nutritional status and dentition status.

KNOWLEDGE TRANSFER STATEMENT

The findings from this study suggest that older adults with fewer teeth and therefore less efficient occlusion are at higher risk for malnutrition than those with more teeth and better occlusion. Health care professionals should include screening for dentition and malnutrition as part of their routine practice to identify patients who may have tooth loss and be at risk of malnutrition and refer them accordingly for interventions to optimize oral health and nutritional status.

Effect of isometric exercises on the masseter muscle in older adults with missing dentition: a randomized controlled trial

Maintaining oral function in older individuals with missing teeth is important for leading a healthy and independent life. This study aimed to evaluate whether simple isometric exercises can maintain and improve the oral function [maximum occlusal force (MOF) and masticatory ability (MA)] and the masticatory muscle properties [masseter muscle thickness (MMT) and echo intensity (MMEI)] in older adults during the maintenance phase of removable prosthetic treatment. Participants were randomly categorized into the intervention and control groups. The mouthpieces were distributed, and participants were instructed to use them for exercising. The intervention group was instructed to perform maximum clenching for 10 s, whereas the control group was instructed to tap the teeth at an arbitrary speed for 10 s. Both were repeated five times at an interval of 5 s between each activity and twice daily for 4 weeks. The outcomes were measured after a month of exercise. The intervention group showed a significant improvement in the MOF, MMT during contraction, MMT at rest and MMEI during contraction. There were no significant differences in the MA and MMEI at rest. In the control group, no improvement was observed in any of the parameters. When the isometric exercises were performed using a mouthpiece, there was an improvement in the oral function and masseter muscle properties in older individuals with Eichner B status who used dentures.

Patient-reported outcome measures of edentulous patients restored with single-implant mandibular overdentures: A systematic review

AIM

To review the literatures concerning the effect of the single-implant mandibular overdenture (SIMO) on patient-reported outcome measures (PROMs) and masticatory function in the fully edentulous patients.

MATERIALS AND METHODS

Electronic databases (PubMed, Cochrane Library, EMBASE and Web of Science) were searched, complemented with manual resources. Prospective studies published in English up to February 2020 reporting the effect of SIMO on PROMs and masticatory function in the edentulous patients were included. This review focused on oral health-related quality of life (OHRQoL), satisfaction and masticatory function outcomes.

RESULTS

Of 1157 initially screened articles, 9 randomised controlled trials (RCTs) and 8 prospective studies involving 551 subjects fulfilled the inclusion criteria. Two RCTs were graded as high risk of bias or some concern, while others were low risk. All prospective studies had adequate representativeness and assessment, but only one study had a controlled cohort. In general, the edentulous patients restored with SIMOs had improved OHRQoL and general satisfaction compared to those with conventional complete dentures (CCDs), but the outcome of masticatory function was controversial. Compared with two-implant mandibular overdenture (TIMO), SIMO showed no significant differences regarding general satisfaction and satisfaction with speech, comfort, chewing ability, aesthetics and social life. Conflicting results were observed in OHRQoL and satisfaction with retention and stability. Better masticatory performance was observed in TIMO group than SIMO group.

CONCLUSION

Within the limitation of this review, SIMO is featured with better OHRQoL and satisfaction than CCD. SIMO and TIMO rendered similar patient satisfaction, but TIMO had better masticatory performance.

Semi-powered exoskeleton that regulates the muscular activity of jaw movement for oral functional rehabilitation/training

The sequential oral functions of mastication and swallowing are well tuned in humans. To prevent oral hypofunction as a risk factor for systemic frailty by oral motor training, semi-powered exoskeleton was developed and evaluated its loading/assist effects by monitoring electromyography signals and saliva secretion in healthy persons. The actuator of the driving unit combined mechanical and powered mechanics and was driven alternatively by an unpowered stainless-steel spring system for jaw-opening training by loading and a powered shape-memory alloy spring system to assist jaw closing. Sequential device movement was controlled by two electronic circuits with two magnetic switching systems to match human jaw movement. This exoskeleton realized a 25% increase of jaw-opening muscular activity for training, 15% saving of jaw-closing muscular activity for assistance, and 15% enhancement of saliva secretion, which could contribute to the prevention of oral frailty by maintenance and strengthening of oral function in the upcoming super-aging society.

Association between oral health status and future dietary intake and diet quality in older men: The PRIME study

OBJECTIVES

This study investigated whether oral health status, defined as number of natural teeth and subsequent prosthodontic rehabilitation, was associated with future dietary intake and diet quality in older adults in The Prospective Epidemiological Study of Myocardial Infarction (PRIME).

METHODS

PRIME was originally established to explore cardiovascular risk factors in 50-59 year old men in Northern Ireland (1991-1994). A rescreening phase assessed oral health (2001-2004), while diet was assessed in 2015. Diet quality was characterised by the Dietary Diversity Score and Mediterranean Diet Score. In the current analysis, associations between oral health status, dietary intake and quality were assessed using regression models in 1096 participants.

RESULTS

Amongst study participants, the overall mean number of teeth was 18.5, 51.5 % had ≥21 natural teeth and 49.6 % wore dentures. Oral health status was categorised into five groups: 21-28 teeth with (n = 111) and without (n = 453) dentures, 1-20 teeth with (n = 354) and without (n = 99) dentures and edentate with dentures (n = 79). After full adjustment, men with ≥21 teeth and dentures had a higher future intake of fruit, vegetables, and nuts, and diet quality scores, compared to those with <21 teeth with dentures. Edentate men with dentures were less likely to achieve the future fruit dietary recommendation.

CONCLUSIONS

Having ≥21 natural remaining teeth positively affected the future intake of fruit, vegetables, and nuts, as well as diet quality. Dentures may be beneficial in men with ≥21 natural remaining teeth, as they were associated with an increased future intake of fruit, vegetables, and nuts and better diet quality.

CLINICAL SIGNIFICANCE

Oral health status is associated with dietary intake, after an average time period of 13 years, with those with a larger number of natural teeth having a better diet quality. Further research is required to investigate this relationship in larger, diverse populations with more detailed dietary assessment.

Association between oral health-related quality of life and nutritional status among older adults in district of Kuala Pilah, Malaysia

Background

Poor oral health has an impact on food choices and intake of important nutrients among older population. The use of oral health-related quality of life instruments along with the clinical dental indicators can help to assess the oral problems that lead to nutritional problems in this group. This study aims to determine the association between oral health-related quality of life (OHRQoL) and nutritional status among a group of older adults in Kuala Pilah district, Malaysia.

Methods

A cross-sectional study was carried out on 446 older adults aged 50 years and above from 20 randomly selected villages. Respondents were interviewed to collect information on their demographic characteristics and oral health perception, followed by physical examination to measure height, weight and body mass index (BMI) of respondents. The validated Malay version of General Oral Health Assessment Index (GOHAI) was used to measure OHRQoL.

Results

About one-third (35.8%) of the respondents had normal BMI. Majority of the respondents were overweight (40.4%) and obese (19.9%), while only a small proportion was underweight (3.9%). Mean GOHAI score was 53.3 (SD = 4.7), indicating low perception of oral health. About 81.6% respondents had moderate to low perception of oral health. Logistic regression analysis showed a statistically significant association between the GOHAI and BMI scores (OR = 2.3; p < 0.01).

Conclusions

Oral health-related quality of life was significantly associated with nutritional condition of respondents. Older adults with poor perception of their oral health were more likely to have unsatisfactory BMI compared to those who perceived their oral health to be good.

The impact of dental status on perceived ability to eat certain foods and nutrient intakes in older adults: cross-sectional analysis of the UK National Diet and Nutrition Survey 2008-2014

BACKGROUND

Many factors determine dietary intake in older adults, including physical health, psychological well-being and socio-economic status. Dental status may also be important. The aim was to examine how dental status impacts perceived ability to eat to certain foods, nutrient intake and nutritional status in UK older adults.

METHODS

Data collected by the National Diet and Nutrition Survey Rolling Programme was analysed. A 4-day food diary assessed dietary intake, while a Computer Assisted Personal Interview collected socio-demographic, health behaviour and oral health information. Participants aged 65 years and over (n = 1053) were categorised into three groups according to their dental status: edentate with dentures (E-DEN, n = 292), dentate with dentures (D-DEN, n = 305) or dentate with no dentures (DEN, n = 456). A total of 515 participants provided a blood sample that was used to assess nutrient concentrations including vitamin B12, vitamin C, ferritin, vitamin B6 (pyridoxal-5-phosphate, PLP), retinol, β-carotene and 25-hydroxyvitamin D (25-OH-D). Multiple regression methods were performed to examine cross-sectional associations between dental status, food selection, nutrient intake and nutritional status.

RESULTS

Both E-DEN and D-DEN groups, compared with the DEN group, were more likely to report difficulty eating apples, raw carrots, lettuce, nuts, well-cooked steak and crusty bread (P < 0.01). No group differences were observed in perceived ability to eat sliced bread, sliced cooked meats and cheese. The E-DEN group compared with the DEN group had lower mean daily intakes of omega 3 fatty acids (P = 0.006), non-starch polysaccharides (P = 0.001), β-carotene (P = 0.001), folate (P = 0.001), vitamin C (P = 0.008), magnesium (P < 0.001) and potassium (P < 0.001), and had lower plasma vitamin B6 PLP (P = 0.001), vitamin C (P = 0.009) and β-carotene (P = 0.015) concentrations, after adjusting for socio-demographic and health behavioural factors. Compared with the DEN group, the D-DEN group did not have lower nutrient intakes or lower blood nutrient concentrations.

CONCLUSIONS

Within this sample of older adults, impaired dental status appears to influence food selection, and intake of important nutrients. Future research should focus on developing dental interventions coupled with dietary counselling to encourage the adoption of healthy eating habits in this high-risk population group.

Sensorial Ability, Mastication and Nutrition of Single-Implant Overdentures Wearers

Abstract The use of two-implant overdentures improves mastication of edentulous elderly patients. However, little is known about the effects of single-implant overdentures (SIO) on oral perception and masticatory function in such elders. This study compared the effects of conventional complete dentures (CD) and SIO on the oral sensorimotor ability (OSA), masticatory function, and nutritional intake of elderly people with residual alveolar mandibular height classified as Class III or IV according to the American College of Prosthodontics. Twelve elders first received new conventional CD, which were later converted to SIO. All variables were evaluated after use of each prosthesis for 2 months. To evaluate OSA, elders closed their eyes and orally identified test pieces prepared from raw carrots. A kinesiographic device was used to measure chewing movements during mastication of a test material (Optocal). Masticatory performance (MP) was determined with the sieving method, and a 3-day food diary verified nutrient intake based on a standard Brazilian Food Composition Table. Data were analyzed using the Wilcoxon signed rank test and Student’s paired t test (P < 0.05). OSA results did not differ according to prosthesis type. However, opening and closing velocities during chewing and MP increased after SIO insertion (P < 0.05). Although no difference was observed in the intake of most nutrients, sodium ingestion decreased after SIO insertion (P < 0.05). SIO use had no effect on OSA, but significantly improved mastication and sodium intake of elders with decreased residual ridges height (Brazilian Registry of Clinical Trials #RBR-3kgttj).

Data Mapping From Food Diaries to Augment the Amount and Frequency of Foods Measured Using Short Food Questionnaires

Collecting accurate and detailed dietary intake data is costly at a national level. Accordingly, limited dietary assessment tools such as Short Food Questionnaires (SFQs) are increasingly used in large surveys. This paper describes a novel method linking matched datasets to improve the quality of dietary data collected. Growing Up in Ireland (GUI) is a nationally representative longitudinal study of infants in the Republic of Ireland which used a SFQ (with no portion sizes) to assess the intake of “healthy” and “unhealthy” food and drink by 3 years old preschool children. The National Preschool Nutrition Survey (NPNS) provides the most accurate estimates available for dietary intake of young children in Ireland using a detailed 4 days weighed food diary. A mapping algorithm was applied using food name, cooking method, and food description to fill all GUI food groups with information from the NPNS food datafile which included the target variables, frequency, and amount. The augmented data were analyzed to examine all food groups described in NPNS and GUI and what proportion of foods were covered, non-covered, or partially-covered by GUI food groups, as a percentage of the total number of consumptions. The term non-covered indicated a specific food consumption that could not be mapped using a GUI food group. “High sugar” food items that were non-covered included ready-to-eat breakfast cereals, fruit juice, sugars, syrups, preserves and sweeteners, and ice-cream. The average proportion of consumption frequency and amount of foods not covered by GUI was 44 and 34%, respectively. Through mapping food codes in this manner, it was possible, using density plots, to visualize the relative performance of the brief dietary instrument (SFQ) compared to the more detailed food diary (FD). The SFQ did not capture a substantial portion of habitual foods consumed by 3-year olds in Ireland. Researchers interested in focussing on specific foods, could use this approach to assess the proportion of foods covered, non-covered, or partially-covered by reference to the mapped food database. These results can be used to improve SFQs for future studies and improve the capacity to identify diet-disease relationships.

The Impact of Replacement Conventional Dentures on Eating Experience

Introduction:

Despite much research on the impact of edentulism and prosthetic rehabilitation on food and nutrient intake, there is little information on how replacing complete dentures affects social and emotional issues around eating.

Objectives:

To investigate, in a cohort study, how replacing conventional complete dentures affects eating-related quality of life (ERQoL). A secondary aim was to test the responsiveness of an Emotional and Social Issues Related to Eating (ESIRE) questionnaire to change in ERQoL.

Methods:

Participants, recruited from the Dental Hospital, Newcastle-upon-Tyne, UK, completed the self-administrated ESIRE questionnaire before and after provision of new conventional complete dentures. Paired t test was used to determine any change between pre- and posttreatment ESIRE scores, which can range from 0 (poor) to 100 (excellent). Cohen’s d effect size was used to measure the magnitude of change in ERQoL. Standardized response mean (SRM) was used to measure the responsiveness of the ESIRE questionnaire to changes in ERQoL.

Results:

Fifty-five participants aged 52 to 85 y (mean, 72 y), including 21 males (42%) and 29 females (58%), completed the study. A statistically significant improvement in the total ESIRE scores was found, mean (SE) +20.3 (3.30), P < 0.001. Equally, all domains of the ESIRE questionnaire showed significant improvements: enjoyment of food/eating, +27.3 (3.63), P < 0.001; self-consciousness/embarrassment, +18.1 (3.88), P < 0.001; interruption to meals, +13.3 (5.27), P < 0.05; confidence when eating, +18.7 (4.84), P < 0.001; time for eating/preparation of meals, +18.5 (4.85), P < 0.001); and functional ability to eat, +18.2 (3.67), P < 0.001). Cohen’s d was large (0.95) for the total score and ranged from medium (0.37) to large (1.30) for all domains. Value of SRM was large (0.87) for the total score and ranged from medium (0.36) to large (1.1) for all domains.

Conclusion:

Denture replacement can directly improve ERQoL. The ESIRE questionnaire was responsive to clinically important changes in ERQoL.

Knowledge Transfer Statement:

The results of this study improve the understanding of the impact of denture replacement on eating-related quality of life (ERQoL). Clinicians are encouraged to pay more attention to the impact of wearing conventional complete dentures on social and emotional issues around eating. The findings should motivate clinicians and inspire specialists in prosthodontics and oral rehabilitation to continue providing conventional complete dentures as a suitable treatment option for edentulous patients.

Bite Force Evaluation in Complete Denture Wearer with Different Denture Base Materials: A Randomized Controlled Clinical Trial

AIM

The aim of this study is to evaluate the maximum bite force (MBF) with different denture base materials in completely edentulous patients.

MATERIALS AND METHODS

MBF was evaluated in randomly selected 100 completely edentulous patients. Patients were selected from the Outpatient Clinic, College of Dentistry, Aljouf University, Saudi Arabia. The patients were randomly divided into two equal groups: Group I (control group): Patient received a conventional heat-cured acrylic complete denture (Vertex™ Regular, Vertex-Dental B.V., The Netherlands) and Group II (experimental group): Patient received a thermoplastic complete denture (Vertex™ ThermoSens, Vertex-Dental B.V., The Netherlands). MBF measurements were taken at the time of new denture placement and after 6 months of denture use. Statistics were analyzed using independent t-test to compare the MBF measurements between both groups.

RESULTS

At the time of denture placement, there was no significant difference in bite force measurements between both groups. Bite force is increasing considerably after 6 months of denture use, and it was higher than MBF recorded at the time of new prosthesis placement in the same group. The MBF values were considerably higher in patients with a thermoplastic denture than patients with conventional acrylic denture with statistically significant difference after 6 months of denture use.

CONCLUSION

After 6 months of denture use, patients with a thermoplastic denture have a higher biting force than patients with a conventional acrylic denture. Therefore, it could be considered a treatment plan option according to the ridge nature and quality to solve the problem of diminished bite force in old age patients.

Relationship between oral health and Fried's frailty criteria in community-dwelling older persons

BACKGROUND

Oral health and frailty might be linked through several pathways, but previous studies are scarce. This study examined the association between oral health and components of Fried's frailty phenotype.

METHODS

This cross-sectional analysis was based on a sample of 992 community-dwelling persons aged 73 to 77 years observed in the 2011 follow-up of the Lausanne 65+ cohort (Lc65+) study. Data were collected through annual mailed questionnaires, interview and physical examination. Oral health was assessed according to self-reported oral pain and masticatory ability. Frailty was defined as meeting at least one criterion of the Fried's phenotype.

RESULTS

Oral pain was reported by 14.8% and chewing problems by 9.7%. Impaired masticatory ability (IMA) was more frequent in subjects with missing teeth or removable dentures (13.5%) than among those with full dentition or fixed dental prostheses (3.2%). In logistic regression analyses adjusting for demographics, alcohol consumption, smoking, comorbidity and financial difficulties, persons with oral pain and those with chewing problems had significantly higher odds of being frail (adjusted OR_pain = 1.72; 95% CI 1.17-2.53 and adjOR_IMA1.70; 1.07-2.72, respectively). Lack of endurance was associated with both oral pain (adjOR = 3.61; 1.92-6.76) and impaired masticatory ability (adjOR = 2.20; 1.03-4.72). The latter was additionally linked to low physical activity (adjOR = 2.35; 1.29-4.28) and low gait speed (adjOR = 3.12; 1.41-6.90), whereas oral pain was associated with weight loss (adjOR = 1.80; 1.09-2.96) and low handgrip strength (adjOR = 1.80; 1.17-2.77).

CONCLUSION

Self-reported oral pain and chewing impairment had a significant relation with frailty and its components, not only through a nutritional pathway of involuntary weight loss. Longitudinal analyses are needed to examine whether a poor oral condition might be a risk factor for the onset of frailty.

A influência de dentaduras implanto-suportadas sobre o estado nutricional de indivíduos idosos

RESUMO Objetivo: avaliar o estado nutricional de indivíduos idosos submetidos a procedimentos de reabilitação oral cirúrgico-protético. Métodos: foram avaliados 15 pacientes completamente edêntulos com idade igual ou superior a 60 anos (10 mulheres e 5 homens). Todos os indivíduos usaram prótese removível em ambos os arcos e tiveram suas próteses mandibulares substituídas por próteses com implante, foram submetidas à avaliação nutricional, compreendendo aspectos antropométricos, análise bioquímica do sangue e avaliação dietética antes da cirurgia e três e seis meses após a cirurgia. Resultados: a análise estatística da avaliação antropométrica não revelou diferença significativa entre os períodos de estudo, para todos os parâmetros investigados. A avaliação bioquímica revelou um aumento significativo da albumina três meses após o tratamento odontológico, voltando a níveis inferiores após seis meses. A avaliação dietética evidenciou que a ingestão calórica, macronutrientes proteínas e carboidratos não foram alterados após o tratamento odontológico. Por outro lado, a ingestão de lipídios foi menor seis meses após o tratamento odontológico em comparação com os resultados anteriores. Conclusão: portanto, a colocação de próteses dentárias completas implantadas nos idosos investigados neste estudo não modificou a condição nutricional no curto prazo, sugere que os sujeitos mantiveram as características alimentares anteriores.

Evidence of dietary calcium and vitamin D inadequacies in a population of dental patients

OBJECTIVES

To determine the dietary calcium and vitamin D intake of a cohort of dental patients identified as being at risk of inadequacy based on a 24-hour food recall.

METHODS

A retrospective chart analysis was carried out on 5-day food record and nutrient analyses of 670 dental patients aged 18 to 82 years obtained over a 10-year period. All patients had scored poorly on a 24-hour food recall survey during their initial examination.

RESULTS

The overall mean and median calcium and vitamin D intakes of the patients were significantly lower than the current estimated needs for the general population. Although calcium intake did not change over the 10-year period, vitamin D consumption decreased. The greatest dietary intake inadequacies for both calcium and vitamin D were seen in both male and female patients over age 50 years.

CONCLUSIONS

A 24-Hour Food Recall Questionnaire may be an effective means for the oral health professional to screen patients for calcium and vitamin D and other nutrient inadequacies.

CLINICAL SIGNIFICANCE

Screening for potential dietary inadequacies of calcium and vitamin D may identify patients potentially at risk for poor bone health. Our results indicate that the dental health professional can obtain evidence necessary to change patient dietary behavior and thus contribute to successful treatment outcomes.

Relationship Between Frailty and Oral Function in Community-Dwelling Elderly Adults

OBJECTIVES

To determine the standard values of and age-related changes in objective oral function of healthy older people; compare oral function of robust, prefrail, and frail older people; and determine the association between oral function and frailty.

DESIGN

Cross-sectional analysis.

SETTING

General community.

PARTICIPANTS

Elderly adults (≥65) from the Obu Study of Health Promotion for the Elderly were included and assigned to the robust, prefrail, and frail groups (N = 4,720).

MEASUREMENTS

Each participant underwent detailed physical testing to assess frailty. The frailty phenotype was defined according to the presence of limitations in three or more of the following five domains: mobility, strength, endurance, physical activity, and nutrition. The numbers of present teeth and functional teeth were counted, and occlusal force, masseter muscle thickness, and oral diadochokinesis (ODK) rate were measured, along with sociodemographic and functional status, comorbidities, and blood chemistry.

RESULTS

The number of present teeth, occlusal force, masseter muscle thickness, and ODK rate decreased with age. The frail group had significantly fewer present teeth (women aged ≥70), lower occlusal force (women aged ≥70; men aged ≥80), lower masseter muscle thickness, and lower ODK rate than the robust group. Multivariate analysis indicated that age, Geriatric Depression Scale score, skeletal muscle mass index, Mini-Mental State Examination score, hypertension, diabetes mellitus, albumin and triglyceride levels, and oral function were significantly associated with frailty.

CONCLUSION

Age-related differences in oral function were found in older adults. Moreover, frail older individuals had significantly poorer oral function than prefrail and robust individuals. The risk of frailty was associated with lower occlusal force, masseter muscle thickness, and ODK rate.

Oral health in the elderly patient and its impact on general well-being: a nonsystematic review

Data on the oral health of the elderly depict a worrying situation, with an elevated prevalence of caries and moderate periodontal disease, frequent edentulism, and numerous cases of dry mouth and oral cancer. There is wide evidence that periodontitis is a risk factor for certain systemic diseases, and impaired oral health has been associated with mastication and nutritional problems, especially among the elderly, with highly negative effects on their quality of life. In this nonsystematic review, the authors discuss the importance of evaluating the oral health of the geriatric population in a comprehensive manner, beyond simple clinical assessments.

Position of the Academy of Nutrition and Dietetics: oral health and nutrition

It is the position of the Academy of Nutrition and Dietetics that nutrition is an integral component of oral health. The Academy supports integration of oral health with nutrition services, education, and research. Collaboration between dietetics practitioners and oral health care professionals is recommended for oral health promotion and disease prevention and intervention. Scientific and epidemiological data suggest a lifelong synergy between diet, nutrition, and integrity of the oral cavity in health and disease. Oral health and nutrition have a multifaceted relationship. Oral infectious diseases, as well as acute, chronic, and systemic diseases with oral manifestations, impact an individual's functional ability to eat and their nutrition status. Likewise, nutrition and diet can affect the development and integrity of the oral cavity and progression of oral diseases. As knowledge of the link between oral and nutrition health increases, dietetics practitioners and oral health care professionals must learn to provide screening, education, and referrals as part of comprehensive client/patient care. The provision of medical nutrition therapy, including oral and overall health, is incorporated into the Standards of Practice for registered dietitians and dietetic technicians, registered. Inclusion of didactic and clinical practice concepts that illustrate the role of nutrition in oral health is essential in education programs for both professional groups. Collaborative endeavors between dietetics, dentistry, medicine, and allied health professionals in research, education, and delineation of practice roles are needed to ensure comprehensive health care. The multifaceted interactions between diet, nutrition, and oral health in practice, education, and research in both dietetics and dentistry merit continued, detailed delineation.

A preliminary investigation into the use of denture adhesives combined with dietary advice to improve diets in complete denture wearers

OBJECTIVES

To investigate how nutritional advice and denture adhesives may be associated with eating healthier foods.

METHODS

35 edentulous subjects (13 males and 22 females, mean age 73.9 years (55-84 years)), wearing complete dentures more than one year old, completed validated questionnaires analysing saturated fat, protein, Vitamin C, the number of servings of fruit/vegetables. In addition subjects completed the NDNS and OHIP Edent questionnaires. At baseline, nutritional information and the use of denture adhesive was provided. Subjects returned after 30 consecutive days and the questionnaires were repeated. A Wilcoxon signed rank test was used to test the effect of the denture adhesive on diet and on quality of life measures.

RESULTS

The subjects increased mean intake from 2.2 portions of fruit/vegetables a day to 3.6. Fat and saturated fats were reduced from 23.2g to 11.3g and Vitamin C intake increased by 34.4mg. All were statistically significant (p<0.0001). There was a statistically significant improvement over the 30-day treatment period in subjects' ability as measured by using OHIP Edent scores to bite (p=0.017) and chew a range of foods (p=0.007).

CONCLUSION

Within the confines of the study, use of simple dietary advice and denture adhesives improved diet.

CLINICAL SIGNIFICANCE

The results of this pilot study suggest that denture fixatives may improve dietary behaviour of complete denture wearers.

Association between oral health and body cell mass in hospitalised elderly

OBJECTIVE

To examine whether oral health in hospitalised elderly was associated with body cell mass (BCM) measured with Bioimpedance spectroscopy.

BACKGROUND

Body cell mass is the tissue producing the metabolic work necessary for all body functions. BCM is mainly muscle tissue. Low BCM is associated with diseases, ageing and poor nutritional status. Reduced oral health is also associated with these parameters; thus, BCM and oral health may be related.

METHODS

Body cell mass was measured using Bioimpedance spectroscopy in 138 acutely hospitalised elderly ≥70 years. The number of own teeth, posterior occluding tooth pairs and decayed teeth were registered. Oral hygiene was registered with Mucosal-Plaque Score, an index based on assessment of plaque accumulation and mucosal/gingival inflammation. Mini Nutritional Assessment-Short Form, body mass index and handgrip strength were used as nutritional indicators. Comorbidity was assessed with Cumulative Index Rating Scale.

RESULTS

Mean age was 83.2 ± 5.9 years, ranging from 70 to 101 years. Dentition status was significantly and positively associated with BCM. Reduced oral hygiene was significantly associated with low BCM. These findings remained significant after adjusting for confounders.

CONCLUSION

These results show that compromised oral health was significantly associated with reduced BCM in hospitalised elderly.

The association of tooth loss with all-cause and circulatory mortality. Is there a benefit of replaced teeth? A systematic review and meta-analysis

We systematically reviewed whether the number of teeth is related to all-cause or circulatory mortality and whether replaced teeth are protective against all-cause or circulatory mortality. The search was based on the PubMed database. All cohort studies published in peer-reviewed journals were selected. Studies on periodontal disease and mortality were excluded if they did not provide information on the number of teeth. Risk estimates from studies with appropriate exposure definition, confounder adjustment and sample size were included in a meta-analysis. Three high-quality studies found a relationship between the number of teeth and circulatory mortality, whereas a moderate study did not. Two out of four moderate- to high-quality studies reported a relationship between the number of teeth and all-cause mortality. No study has investigated whether replaced teeth are protective against mortality. Therefore, denture use was taken as proxy. The methodological quality of studies on denture use and mortality was generally low to moderate. The findings of two moderate studies indicated an effect of prosthodontic replacements on all-cause mortality, which was supported in bias analysis. It is open whether competing risks of cause-specific death other than circulatory mortality reduce an effect of the number of teeth on all-cause mortality. An effect of denture use on circulatory mortality remains to be established, as well as whether the number of replaced teeth affects mortality. Specifying the role of potential pathways by which tooth loss-related mortality is mediated will possibly increase the value of dental treatment for general health.

Association of dental prosthetic condition with food consumption and the risk of malnutrition and follow-up 4-year mortality risk in elderly Taiwanese

OBJECTIVE

To determine the impact of dental prosthetic condition on food consumption, risk of malnutrition and follow-up 4-year mortality risk in elderly Taiwanese.

DESIGN AND SETTING

Analyzing the data sets of the 1999 and 2003 "Survey of Health and Living Status of the Elderly in Taiwan", a longitudinal cohort study.

PARTICIPANTS

A national probability sample of 2766 men and women 65 years of age or older.

MEASUREMENTS

Self-reported intake frequencies of major food categories, masticatory ability, food consumption, and the risk of malnutrition assessed with the Mini Nutritional Assessment (short-form) stratified by dental prosthetic condition. Cox regression was used to compare follow-up mortality risk.

RESULTS

Non-denture wearers and removable-denture wearers had poorer masticatory ability and greater nutritional risk and consumed fruits and vegetable less often compared to fixed-denture wearers. Removable-denture wearers also had lower self-perceived nutritional status and BMI compared to fixed-denture wearers. Survival analysis showed that non-denture wearers and removable-denture wearers had lower follow-up 4-year survival. Cox regression analysis showed that removable-denture wearers had increased follow-up 4-year mortality risk compared to fixed-denture wearers adjusted for sociodemographic, lifestyle and health-related factors.

CONCLUSIONS

Based on data of a national sample of a longitudinal cohort study, dental prosthetic condition is a significant factor of nutritional health in the elderly. It can affect food pattern and the risk of malnutrition and mortality of elderly persons. Dental care should be an important part of geriatric health promotion program and fixed-denture is a preferred choice over removable-denture.

Nutritional status and nutritional rehabilitation of elderly living in long-term care

A dolgozat témája a tartós bentlakásos intézményekben élők táplálásához és táplálkozásához kapcsolódó legfontosabb tényezők feltérképezése, a szociális otthonokban élő időskorúak tápláltsági állapotának felmérése, és az eredmények alapján a táplálkozási rehabilitációra javaslattétel. Célkitűzések: A tartós bentlakásos intézményekben élő hatvanévesek és idősebbek (időskorúak) tápláltsági állapotának meghatározása. A tartós bentlakásos intézményekben élő időskorúak testtömegindexének (BMI) változása. Az elmúlt fél évtized során a tartós bentlakásos intézményekben élő időskorúak tápláltságiállapot-változásának megállapítása. Az akut és krónikus betegségek összefüggésének megállapítása a tápláltsági állapottal. A tartós bentlakásos intézményekben élő időskorúak klinikai tápszerrel való ellátottságának felmérése. Annak megállapítása, hogy milyen a feltárt vélelmezett befolyásoló tényezők és a MUST szerinti tápláltsági állapot közötti összefüggés. Módszerek: Összesen 4774 hatvanéves és idősebb (28,9–30,9%-át férfiak, 69,1–71,2%-át nők adták, az összes résztvevő átlagéletkora 77,8±8,9 év volt) tartós bentlakásos intézményben élő, önként jelentkező gondozott tápláltsági állapotát szűrtük 2004-ben és 2006-ban a Malnutrition Universal Screening Tool (MUST) kérdőívvel és az általunk összeállított kérdőívvel, 2008-ban a Nutrition Day 2008 nyomtatványait használtuk. Eredmények: Felméréseink eredményei szerint az alultápláltságra veszélyeztetett idős személyek aránya a szociális otthonokban igen nagy (26,8–77,0%). Az ellátottak 29,5%-ánál tápláltságiállapot-felmérés negyedévente vagy annál ritkábban történik. A tápláltsági állapot multifaktoriális, sok tényező határozza meg a tápláltsági állapotot (például mozgáskorlátozottság, láz). Az étvágytalanság és a nyelési nehezítettség 2,5-szer gyakoribb, a mozgáskorlátozottság, a dementia, valamint a hiányos fogazat a nagy rizikójú idősek csoportjában közel kétszer (1,6–1,7-szer) gyakoribb, mint az idős, szociális otthonban élők körében. Az idegrendszeri kórképek szignifikánsan függnek össze a tápláltsági állapottal. Az idegrendszeri betegségek előfordulási gyakorisága az elmúlt években szignifikánsan nőtt. Következtetések: A táplálkozási rehabilitáció nem ér véget a tápláltsági állapot szűrésével, ellenkezőleg, azzal kezdődik. Annak eredményei alapján elengedhetetlen a táplálkozási irányelvek és szükség esetén a személyre szabott étrend meghatározása.
