Diet, Nutrition, and Oral Health in Older Adults: A Review of the Literature

The oral organ: A new vision of the mouth as a whole for a gerophysiological approach to healthy aging

This article brings a new perspective on oral physiology by presenting the oral organ as an integrated entity within the entire organism and its surrounding environment. Rather than considering the mouth solely as a collection of discrete functions, this novel approach emphasizes its role as a dynamic interphase, supporting interactions between the body and external factors. As a resilient ecosystem, the equilibrium of mouth ecological niches is the result of a large number of interconnected factors including the heterogeneity of different oral structures, diversity of resources, external and internal pressures and biological actors. The manuscript seeks to deepen the understanding of age-related changes within the oral cavity and throughout the organism, aligning with the evolving field of gerophysiology. The strategic position and fundamental function of the mouth make it an invaluable target for early prevention, diagnosis, treatment, and even reversal of aging effects throughout the entire organism. Recognizing the oral cavity capacity for sensory perception, element capture and information processing underscores its vital role in continuous health monitoring. Overall, this integrated understanding of the oral physiology aims at advancing comprehensive approaches to the oral healthcare and promoting broader awareness of its implications on the overall well-being.

Ultrasound analysis of the masseter and anterior temporalis muscles in edentulous patients rehabilitated with full-arch fixed implant-supported prostheses

OBJECTIVES

Total tooth loss is common in the aging population resulting in insufficient chewing function with subsequent weakening of the masticatory muscles. The study aims to evaluate the changes in thicknesses of the masseter and anterior temporal muscle in edentulous patients following the reconstruction of implant-supported fixed prostheses and compare them with the dentate individuals.

MATERIALS AND METHODS

The study was designed as a prospective, single-center, controlled clinical trial. A total of 60 participants were included in the present study. The patients were divided into two groups; Group I (Test Group): 30 edentulous patients who received implant-supported fixed prostheses, Group II (Control Group): 30 dentate individuals of an age and sex-matched group. Ultrasonography was used to measure the cross-sectional thickness of the left and right musculus masseter and anterior temporalis immediately after the cementation of the prosthetic rehabilitation (T1), on the 1st (T2) and 6th (T3) months after rehabilitation and at a single time point in the control group.

RESULTS

The results showed that there were significant comparison differences in muscle thickness at the baseline measurements between groups while at the end of the 6th month, these differences were not significant. The muscle thicknesses of both the masseter and anterior temporalis muscles increased significantly at T2 and T3 compared to T1 in the test group. The asymmetry index between the left and right muscles in the test group and the asymmetry differences between groups also decreased significantly at the end of the 6th month.

CONCLUSION

The implant-supported fixed prostheses significantly increase the thicknesses of the masseter and anterior temporal muscle together with a decrease in the asymmetry between the left and right muscles. At six months, implant-treated patients showed similar muscle thicknesses compared to dentate individuals.

CLINICAL RELEVANCE

The findings suggest that implant-supported fixed prostheses can improve the masticatory function and facial symmetry of edentulous patients.

An evaluation of nutritional impact symptoms and their association with reduced dietary intake in patients with solid tumors at tertiary care hospitals: a multicenter, cross-sectional study from palestine

BACKGROUND

Nutritional impact symptoms (NISs) are proposed to be a key indicator of decreased dietary intake in patients with solid cancer. Cancer patients frequently experience NIS from the disease itself and from disease treatment side effects that impact oral and gastrointestinal health. Thus, this study aimed to investigate the association between NIS and dietary intake among cancer patients in the Nablus district, one of the largest districts in Palestine. This study also sought to identify the types of treatment and other factors related to dietary intake for solid cancer patients.

METHODS

A cross-sectional study was conducted between October 15, 2021, and October 15, 2022. The convenience sampling technique was used to recruit participants from two primary hospital campuses for cancer treatment in the entire region of Nablus Governorate in northern Palestine. To assess the patients, structured questionnaires completed by interviewers during face-to-face interviews with patients were used. The NIS was assessed using a checklist developed based on a literature review and clinical experience. Univariate and multivariate analyses were used to evaluate the correlations between sociodemographic variables and clinical variables and between the NIS and dietary intake. Multiple binary logistic regression analyses were also performed to determine the most influential variables, sociodemographic, clinical, and NIS, on dietary intake.

RESULTS

Data were collected from 290 patients with solid malignancies. The mean age of the participants was 55.04 ± 12.76 years. Multiple binary logistic regressions revealed that dry mouth (odds ratio (OR) = 3.742; 95% confidence interval (CI) = 1.800-7.780; p < 0.001), constipation (OR = 2.707; 95% CI = 1.113-6.581; p = 0.028), taste alteration (OR = 3.620; 95% CI = 1.752-7.481; p = 0.001), and feeling fullness (OR = 8.879; 95% CI = 2.982-26.441; p < 0.001) were significantly related to decreased dietary intake. Biological and hormonal treatments had an inverse association with dietary intake (OR = 0.372; 95% CI = 0.177-0.782; p = 0.009 and OR = 0.383; 95% CI = 0.168-0.874; p = 0.023, respectively).

CONCLUSIONS

This study revealed that many solid cancer patients have reduced food intake due to NIS, such as dry mouth and taste changes. These patients may be at risk of malnutrition. Healthcare professionals should consider these NISs to improve dietary plans and decide whether extra feeding support is needed. The results obtained indicate the need for further research focused on removing limitations in food consumption as an effect of treatment and appropriate nutritional strategies to prevent patient malnutrition.

Clinical evidence for silver diamine fluoride to reduce dentine hypersensitivity: A systematic review

OBJECTIVE

To assess the clinical evidence for silver diamine fluoride (SDF) to reduce dentine hypersensitivity in adults.

METHODS

Two independent researchers searched the English literature in five databases (Scopus, PubMed, Web of Science, EMBASE and the Cochrane Library) up to 15th July 2023 for clinical trials investigating the desensitising effect of professionally applied SDF to manage dentine hypersensitivity in adults aged 18 or above at any follow-up period. The primary outcome was the change in dentine hypersensitivity between baseline and follow-up visits after SDF application regarding any validated pain outcome measures. The Cochrane guidelines were used for the risk of bias assessment.

RESULTS

Three hundred and thirty-one studies were identified, and four of them were finally included. Three of the included studies were rated as having a 'low risk' of bias. The SDF solution reduced dentine hypersensitivity in adults. The percentage reduction in dentine hypersensitivity ranged from 23 % to 56 % after a single application of SDF solution. Moreover, the SDF solution was more effective than potassium nitrate, potassium oxalate and glutaraldehyde plus hydroxyethyl methacrylate in reducing dentine hypersensitivity. Meta-analysis indicated a more significant reduction in visual analogue scales (1-10) by 1.35 (95 % CI:0.9-1.8; p<0.00001) after receiving the SDF application than controls.

CONCLUSION

The included clinical trials showed that SDF solution reduced dentine hypersensitivity in adults. However, clinical trials are few, and their protocol varied from one another. Further well-designed clinical trials should be conducted to provide more evidence on its use to manage dentine hypersensitivity.

CLINICAL SIGNIFICANCE

SDF is cleared as desensitizing agents by the US Food and Drug Administration to manage dentine hypersensitivity, which induces pain, limits food choice, and impacts the quality of life. Evidence from this systematic review informs clinicians and provides researchers insight for future research on SDF use for dentine hypersensitivity.

Tooth Wear in Older Adults: A Review of Clinical Studies

INTRODUCTION

Tooth wear is a prevalent dental condition among older adults, leading to pain and adversely affecting aesthetics, functionality, and their overall quality of life. This review aims to update the information on tooth wear in older adults from the past five years and to provide guidance on the clinical management of tooth wear in older adults.

METHODS

A literature search was conducted in three electronic databases, Scopus, Pubmed, and Embase, for English publications from January 2019 to December 2023 on clinical studies with participants aged 65 or above on tooth wear. A total of 307 articles were retrieved and 14 articles were finally included as references for this study.

RESULTS

This review highlights the common causes of tooth wear and various risk factors, such as medical conditions, hyposalivation, dietary habits, oral hygiene practices, parafunctional habits, and occlusal factors, associated with tooth wear. It is crucial for oral health care professionals to diagnose and manage tooth wear at an early stage through a risk assessment and a clinical examination to avoid complex restorative procedures. Tooth wear management should prioritize prevention, aiming to control etiological and risk factors while employing non-restorative treatments. Restorative intervention, if indicated, should be simple, minimally invasive, and cost-effective. Tooth wear progression should be monitored regularly to determine if a further intervention is needed.

CONCLUSION

Since the clinical studies on tooth wear in older adults over the past five years are limited and mainly cross-sectional, more interventional clinical studies are warranted to provide more clinical guidance on tooth wear management in older adults.
