Comparison of chewing ability, oral health related quality of life and nutritional status before and after insertion of complete denture amongst edentulous patients in a Dental College of Pune

Influence of prosthodontic rehabilitation and dietary advice on glycaemic control, nutritional status and oral health-related quality of life of older adults with type 2 diabetes

OBJECTIVES

This prospective clinical study aimed to determine the influence of oral prosthodontic rehabilitation with partial removable dentures and simplified dietary advice on glycaemic control, nutritional status and oral health-related quality of life (OHRQoL) of older adults with type 2 diabetes.

BACKGROUND

Individuals with tooth loss who did not wear complete or partial dentures are more likely to be at nutritional risk, suggesting that using dental prostheses would benefit the re-establishment of an adequate nutritional status and potentially improve quality of life. Nutritional therapy is essential for diabetes prevention, treatment and management, favouring glycaemic control. The literature provides little evidence on the contribution of partial removable dentures to improving diabetes control, nutritional profile and satisfaction in older adults, especially those with type 2 diabetes.

MATERIALS AND METHODS

Older individuals diagnosed with type 2 diabetes mellitus, aged 60 years or older and needing oral rehabilitation with partial removable dentures were eligible for this prospective study. The primary outcome measure was glycaemic control, measured by glycated haemoglobin (HbA1c) levels. The Oral Health Impact Profile (OHIP-14) questionnaire and the Mini Nutritional Assessment short-form (MNA-SF) represented secondary outcome measures. These measures were assessed at baseline and 12 months of follow-up after prosthesis delivery, combined with simple dietary advice in pamphlet form. The data were analysed using the Wilcoxon matched-pairs test.

RESULTS

Forty-four patients who met the inclusion criteria and required treatment with removable partial dentures were selected for this study, which was carried out for a year. During this period, seven participants declined to participate because they moved to another city. Hence, a final sample of 37 participants (16 men and 21 women, average age of 65.8 years, ranging from 60 to 83 years) were included in the study. No laboratory parameter (HbA1c levels) changed significantly during the investigation. The number of older adults at risk of malnutrition was significantly lower at 12 months than at baseline. Furthermore, nutritional status significantly improved 12 months after prosthodontic treatment combined with dietary advice, and the effect sizes were large. OHRQoL significantly improved after prosthodontic therapy combined with dietary advice.

CONCLUSIONS

Prosthodontic treatment with partial dentures associated with simple dietary advice did not influence glycaemic control but improved the nutritional status and OHRQoL of older adults with type 2 diabetes.

The effect of prosthetic rehabilitation with or without dietary advice on nutritional status in elderly patients: a systematic review

BACKGROUND

Elderly people frequently report tooth loss, affecting their nutritional status. There is a gap in the scientific evidence about the influence of prosthodontic rehabilitation on nutritional status.

OBJECTIVE

To investigate the influence of prosthodontic rehabilitation combinates or not with dietary advice on nutritional status in elderly patients.

METHODS

A systematic literature search was conducted in three electronic databases to identify randomized clinical trials that evaluated the effect of prosthetic rehabilitation on nutritional status in subjects aged 60 years or older, with a follow-up of at least 1 month after prosthesis rehabilitation.

RESULTS

Of the 1517 articles identified in the initial search, 12 were selected for the final review. No significant difference between the types of prosthesis were found regarding the chewing by the elderly population. Although patients who received prosthetic treatment had significant improvement in chewing ability, a consistent pattern of improvement in nutritional status was not observed when they did not receive dietary advice. In addition, the association between the condition of the dentition, the masticatory performance and nutritional change of elderly patients has been found. Studies that evaluated simultaneous complete denture treatment and simple dietary advice showed an improvement of nutrient intake in elderly patients.

CONCLUSIONS

Isolated prosthetic rehabilitation may not have the effect of exerting a change in nutritional status of edentulous elderly patients. In general, simultaneous dietary consulting and prosthetic treatment in combination may improve dietary habits, since masticatory capacity and efficiency are not the only factors that influence the nutritional status of a patient.

What Is the Relationship between the Chewing Ability and Nutritional Status of the Elderly in Korea?

This study aims to determine the relationship between chewing ability and the nutritional status of the elderly in Korea. This study utilized the data from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted from 2013-2018 for persons who were ≥65 years of age. Of the 7835 subjects, 43.2% had chewing difficulty. Compared to the normal group, the chewing difficulty group had more stress, lower exercise frequency, less snack intake, a lower frequency of eating out, and a higher proportion of food insecurity. The chewing difficulty group had significantly lower food intake compared to the normal group, including various food groups such as cereals and grain, potatoes, fruits, meat, and milks and dairy products. The intake of fresh fruits was 24.5% lower and the intake of plant food (fresh fruits and nonstarchy vegetables) was 17.8% lower in the chewing difficulty group compared to the normal group. In addition, the intake of most nutrients (carbohydrates, fat, calcium, phosphorus, sodium, potassium, vitamin A, riboflavin, niacin, and vitamin C) was significantly lower in the chewing difficulty group than in the normal group. The chewing difficulty was significantly associated with undernutrition (OR = 1.63). In conclusion, chewing ability is closely related to food and nutrient intake among the elderly, which can decrease the quantity and quality of diet and is also related to undernutrition. Therefore, it is necessary to develop customized nutrition programs and aging-friendly food products that consider the chewing ability of the elderly.

Development of patient-centric eating advice for complete denture wearers

BACKGROUND

Edentulous people eat less healthily, and wearing dentures impairs eating function and enjoyment.

OBJECTIVE

To apply a sequential approach to integrate scientific evidence, and patient and professional experience to co-develop intervention to support better eating with dentures.

METHODS

Focus groups, two with purposive samples of patients and two with dental professionals, explored experiences and opinions about advice on eating with complete dentures. Findings were distilled with evidence from the literature to underpinned concepts for eating interventions. User engagement informed prioritisation of ideas and led to the development of a leaflet on eating with dentures.

RESULTS

Patients receive no advice on what they can realistically expect when eating with dentures, and professionals lacked confidence to provide eating advice. Patients did not think dentists a credible provider of eating advice, feeling peer support more appropriate and offering numerous strategies for eating with dentures. Concepts for eating intervention included a patient leaflet, Web-based eating interventions, patient support blogs, waiting room videos and improved nutrition training for dental professionals. User feedback informed prioritisation of ideas, leading to the development of a leaflet on eating with dentures. Justified by the data, the leaflet focused on patient-generated tips for overcoming the functional limitations of eating with dentures, and unobtrusive healthier eating advice. Face validity with users confirmed acceptability.

CONCLUSION

A systematic and rigorous integration of scientific evidence, expert experience and patient input has developed a patient-centric, evidence-based approach to a patent leaflet on eating with dentures that, based on initial face validity, is likely to be well received.

Eating Advice for People Who Wear Dentures: A Scoping Review

Objective: A scoping review of available advice to address eating problems experienced by people who wear dentures was conducted in accordance with the PRISMA statement. The objective was to identify and map type, volume, and content of the available eating advice. Methods: Medline, CINAHL, and grey literature databases and Google were searched. Relevant content pertaining to study type, peer-review vs. grey literature, country of origin, advice content, and methods to evaluate effectiveness was mapped. Results: Of the 4591 records identified from peer-reviewed literature, 56 full papers underwent duplicate screening, resulting in 26 papers (from Germany (n = 1), Europe (n = 1), India (n = 2), Japan (n = 7), UK (n = 6), USA (n = 6), or other (n = 3)) being included in the review. These yielded 18 different items of relevant eating advice. Of the 258 screened websites, 63 were included, yielding 30 different items of eating advice. The most-cited advice was to eat soft food and avoid hard and sticky food, cut food into bite-sized pieces, and chew on both sides of the mouth and chew slowly and thoroughly. The identified advice was not supported by reference to peer-reviewed evidence. Advice included some conflicting messages and some advice was non-compliant with authoritative nutritional advice (e.g., avoid red meat, take a vitamin supplement). Conclusion: There is support for providing eating advice at the time of denture provision. A broad range of advice based on clinical experience to support people who wear dentures to overcome the functional limitations exists. However, the efficacy of this advice in improving diet and eating experience has not been tested.

The effect of complete dentures on edentulous patients' oral health-related quality of life in long-term: A systematic review and meta-analysis

BACKGROUND

To evaluate whether the long-term use of complete dentures (CD) into promotes significant changes in the oral health-related quality of life (OHRQoL) in edentulous patients.

METHODS

A systematic review and meta-analysis was conducted. A broad search in Pubmed, Web of Science, Scopus, Cochrane Library, Grey Literature, clinical trials registers and manual search was done. The eligibility criteria were based on population, intervention, comparisons and outcome: (P) edentulous patients, (I) CDs rehabilitation, (C) OHRQoL after CD, (O) change in scores of OHRQoL. Two independent reviewers applied the eligibility criteria, collected qualitative data, performed methodological quality and evaluated the certainty of the evidence (grading of recommendations assessment, development and evaluation). The meta-analysis was analyzed in RevMan 5.4 with 95% confidence intervals (CIs) and P < 0.05.

RESULTS

A total of 2452 records were identified. Twenty-four articles were included in qualitative synthesis. Nineteen studies were qualified as good, 3 as fair and 2 as poor quality. Twelve studies were included in quantitative analysis (meta-analysis). The use of CD did not improved OHRQoL in a period of 3 months through the assessment of the Geriatric Oral Health Assessment Index (GOHAI) instrument (P = 0.55; CI; 6.86 [-15.60, 29.31]), and Oral Health Impact Profile-14 (OHIP-14) (P = 0.05; CI; -14.91 [-29.87, 0.04]), with very low certainty of evidence. In a long term, 6 months, GOHAI instrument (P < 0.00001; CI; 16.22 [10.70, 21.74]), OHIP 20 (P = 0.02; CI; -11.09 [-20.54, -1.64]) and OHIP-EDENT (P = 0.0004; CI; -8.59 [-13.32, -3.86]) showed improvement on OHRQoL, with very low and low evidence of certainty, respectively.

CONCLUSION

CD has the strong potential to contribute to oral health-related quality of life in long-term.

Impact of Wearing Dentures on Dietary Intake, Nutritional Status, and Eating: A Systematic Review

INTRODUCTION

A key purpose of denture provision is to enable eating, yet the body of evidence pertaining to the impact of dentures on wide-ranging nutritional outcomes has not been systematically reviewed.

OBJECTIVES

To systematically review published evidence pertaining to the effect of wearing removable dental prosthesis on dietary intake, nutritional status, eating function, and eating related-quality of life (ERQoL).

METHODS

Eight questions relating to the impact of wearing dentures on nutritional outcomes were addressed. The target population was healthy adults aged ≥18 y. Data sources included Medline, Embase, CINAHL, and PubMed. Included were all human epidemiologic studies. The Newcastle-Ottawa score was used for appraisal of study quality. Harvest plots, vote counting, and accompanying narrative provided the basis for synthesis.

RESULTS

Of the 1,245 records identified, 134 were retrieved and eligibility assessed by 2 reviewers, and 41 studies were included in the synthesis (14 rated good quality, 20 fair, and 7 poor). The balance of data supported a positive impact of wearing full (5/7 studies) or partial (3/3 studies) dentures (vs. no dentures) on nutritional status, though no clear direction of effect was detected for the impact of dentures on dietary intake. The balance of data clearly showed that objective measures of eating function were compromised in full (14/15 studies) and partial (6/7 studies) denture wearers as compared with the dentate. Data showed that ERQoL was also compromised in denture wearers as compared with the dentate (3/3 studies). However, data showed a positive impact of wearing dentures on ERQoL (5/5 studies) as opposed to wearing no dentures.

CONCLUSION

The balance of evidence shows that despite no clear pattern on impact of wearing dentures on measured dietary intake, in those with tooth loss, wearing dentures can have a positive impact on nutritional status and enjoyment of eating.

KNOWLEDGE TRANSFER STATEMENT

The results of this systematic review can be used to advocate for health care services to address prosthodontic need to benefit nutritional outcomes. The findings will be of use in educating health care professionals on the impact of wearing dentures and not addressing prosthodontic need on nutritional outcomes.

Masticatory performance of different impression methods for complete denture fabrication: A randomized controlled trial

OBJECTIVES

To compare the effect of conventional complete dentures fabricated using two different impression methods on masticatory performance and factors relating to masticatory performance in a randomized controlled trial.

METHODS

A crossover randomized controlled trial was performed with edentulous patients requiring maxillomandibular complete dentures. Mandibular complete dentures were fabricated using two different methods. The conventional method (C) used a custom tray border molded with an impression compound and a silicone. The simplified method (S) used a stock tray and an alginate. Participants were randomly divided into the two groups. In the C-S group, the conventional method was used first, followed by the simplified method; the order was reversed in the SC group. Adjustments were performed four times. The wash out period was 1 month. Masticatory performance as assessed by the mixing of a color-changeable chewing gum (mixing ability). Maximum occlusal force, occlusal contact area, and perceived chewing ability were assessed for each group.

RESULTS

Twenty-seven patients underwent randomization and 24 participants completed the trial. With regard to occlusal contact area, the conventional method showed significantly larger occlusal contact area than the simplified method. No significant differences were observed between the two methods regarding mixing ability, maximum occlusal force, and perceived chewing ability.

CONCLUSIONS

This study showed that complete dentures fabricated with the conventional method had a significantly larger occlusal contact area than those made using the simplified method.

CLINICAL SIGNIFICANCE

Complete dentures fabricated with the conventional method, comprising a preliminary impression using alginate in a stock tray followed by a final impression using silicone impression material in a border molded custom tray, resulted in fewer post-insertion adjustments than the simplified method, potentially contributing to earlier stability of new dentures.

How fast can treatment with overdentures improve the masticatory function and OHRQoL of atrophic edentulous patients? A 1-year longitudinal clinical study

OBJECTIVES

The aim of this prospective clinical study was to evaluate the masticatory function (MF) and subjective perception of patients with poor denture-bearing tissue in relation to change and the time required to identify an improvement in these parameters after rehabilitation with mandibular overdentures (MO) by two narrow-diameter two-piece implants.

MATERIAL AND METHODS

Twenty-three edentulous patients were selected for MO installation. The masticatory function (MF) was evaluated with the masticatory performance (MP) and swallowing threshold (ST) tests. In the MP test, each volunteer was instructed to masticate a portion of Optocal (standardized artificial test food) for 40 masticatory cycles. During the swallowing threshold test, the patients were instructed to chew a new portion of Optocal cubes until they felt the desire to swallow. The MF tests were performed while complete denture (CD) wearers (baseline) and 1, 3, 6, and 12 months after MO loading. In addition, the subjective perception was assessed through the questionnaires Dental Impact on Daily Living (DIDL), Geriatric Oral Health Assessment Index (GOHAI), and Oral Health Impact Profile in Edentulous (OHIP- EDENT) at the baseline and 3, 6, and 12 months after MO loading.

RESULTS

A significant improvement in masticatory function (p < .05) was observed already in the first month of loading. Three months after MO loading, a significant improvement (p < .05) was found in the subjective perception of patients. The effect size indicates that the MO had the greatest impact on the domains related to function and comfort of all questionnaires and in relation to psychosocial domain of the GOHAI. The level of patient satisfaction increased significantly after the MO loading and reached >90% satisfied patients at 12 months.

CONCLUSION

The MO improved both the MF of the patient and their oral health-related quality of life and satisfaction regarding the prosthesis in a short time period.

Impact of implant-supported prostheses on nutritional status and oral health perception in edentulous patients

BACKGROUND & AIMS

Improvement of nutritional status and perception of oral health are supposed to be different with complete conventional denture or implant-supported fixed or removable prostheses. Since no study has been conducted in Lebanon, the aim of our study was to assess the nutritional status and oral heath related quality of life (OHRQoL) in totally edentulous patients after treatment with complete denture or implant supported-prostheses.

MATERIAL AND METHODS

This was an observational clinical prospective study. A convenient sample of Lebanese people aged 60 years or more was selected between September 2013 and July 2015 from the Departments of removable and fixed prosthesis at Saint-Joseph University of Beirut. The treatment options included complete denture, implant-supported complete denture and implant-supported fixed prostheses. Nutritional status and OHRQoL were assessed with the Mini-Nutritional Assessment Index (MNA) and the Geriatric Oral Health Assessment Index (GOHAI) respectively at Baseline (first visit before treatment), 2-3 weeks after treatment (t1), 3 months (t2) and 6 months (t3) after treatment.

RESULTS

Fifty-one participants (mean age: 69.39 ± 7.164 years) were included. The results have shown an improvement over time in nutritional status and OHRQoL for all treatment groups. However, 2-3 weeks after treatment the number of participants at risk of malnutrition was higher with complete removable denture, intermediate with implant-supported complete denture and lower with implant-supported fixed prostheses (p-value = 0.049). Moreover, the mean GOHAI score was significantly lower over time with complete removable denture compared to implant-supported prostheses (p-value <0.05).

CONCLUSION

Our study has shown an enhancement in the quality of life and the nutritional status for implant supported-prostheses compared to conventional removable dentures. Therefore, it is fundamental that dentists communicate with their patients about implant treatment to understand their expectations, to explain the outcomes and achieve the desired clinical result.

Combined effect of new complete dentures and simple dietary advice on nutritional status in edentulous patients: study protocol for a randomized controlled trial

Background

Individuals who are edentulous have a lower intake of fruit, vegetables, fiber, and protein compared with their dentate counterparts because tooth loss is accompanied by a decrease in ability to chew. Whether or not a combination of prosthetic rehabilitation and simple dietary advice produces improvement in dietary intake among edentulous persons is unclear. We aim to investigate the effect of a simultaneous combination of simple dietary advice delivered by dentists and provision of new complete dentures on dietary intake in edentulous individuals who request new dentures.

Methods/design

Through a double-blinded, parallel, randomized controlled trial in which 70 edentate persons who request new complete dentures will be enrolled, eligible study participants will be randomly allocated to either a dietary intervention group receiving dietary advice or to a control group receiving only advice on the care and maintenance of dentures. Outcome measures include daily intake of nutrients and food items, assessed using a brief self-administered diet history questionnaire; antioxidant capacity, determined using blood and urine samples; nutritional status, assessed with the Mini-Nutritional Assessment-Short Form; oral health-related quality of life, assessed with the Japanese version of the Oral Health Impact Profile-EDENT and the Geriatric Oral Health Assessment Index; subjective chewing ability; masticatory performance, assessed using a color-changeable chewing gum and a gummy jelly; patient self-assessment of dentures; mild cognitive impairment, assessed with the Japanese version of the Montreal Cognitive Assessment; and functional capacity, assessed with the Japan Science and Technology Agency Index of Competence. Outcome measures, except for antioxidant capacity, are to be implemented at three time points: at baseline and at 3 and 6 months following intervention. Antioxidant capacity data are to be collected twice: at baseline and at 3 months following intervention. Differences between the groups at 3 and 6 months and within-group changes are to be compared using the paired t test.

Discussion

Simple dietary advice that can be implemented by a dentist would be more practical in clinical practice than tailored dietary counseling. The results of this study will provide beneficial information on dietary intake changes for both edentulous individuals requesting new complete dentures and dentists.
