Abstract
This in vivo mouse model study was conducted to investigate the temporal alteration of the function of CD36 in salivary secretion. CD36 was highly expressed in the parotid gland of BALB/c mice. No significant variations were shown in the CD36 levels in the 8-, 48-, and 72-week-old animals. However, pilocarpine-induced salivary secretion was reduced in an age-dependent manner, showing a significantly low level at the age of 72 weeks. Pilocarpine-induced salivary secretion was significantly reduced by pretreatment with a CD36 inhibitor at 8 and 48 weeks, but not at 72 weeks. In senescence-accelerated mice (SAM), the pilocarpine-induced salivary secretion was significantly reduced at the age of 56 weeks, and a significantly lower amount of CD36 was demonstrated in the parotid gland, compared with the control. These results suggest that the involvement of parotid CD36 in mouse salivary secretion is altered with age.

Tabrizi M, Lee WC. Linking current dental education to gerontological education to meet the oral health needs of growing aging populations. FRONTIERS IN ORAL HEALTH 2023; 4:1232489. [PMID: 37876529 PMCID: PMC10591445 DOI: 10.3389/froh.2023.1232489] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Accepted: 09/25/2023] [Indexed: 10/26/2023] Open
Abstract
Objective This study aimed to recognize the gaps in dental education by studying the current level of geriatric oral health training of recent graduated dentists who have been admitted into an Advanced Education in General Dentistry (AEGD) program. Methods The AEGD program was developed along with the Age-Friendly 4Ms model to enhance current dental education. We adopted the Rapid Cycle Quality Improvement model to test the effectiveness of the training for AEGD residents from 2019 to 2022. A total of 18 residents participated (6 residents each year). A 5-question survey was administered before and after the rotation and Wilcoxon signed-rank with Fisher Exact tests were conducted to compare pre- and post- rotation results. Results All 18 residents have completed pre- and post-program surveys. They self-reported minimal to no training in preparation to provide care to older adults with multiple chronic conditions. After the rotation, residents' confidence in treating older adults was significantly increased (p = 0.011). Meanwhile, residents gained knowledge to apply the 4Ms framework (what matters, medication, mentation, and mobility) to their practices (p = 0.015) and provide age-friendly care for older adults. Conclusion The study identified and addressed the missing link in dental education to gerontological and geriatrics education. More clinical rotations and didactic training to equip residents with competences of providing geriatric oral health are strongly recommended.

Abstract
OBJECTIVE We aim to assess the validity and reliability of the Arabic language translation of the Summated Xerostomia Inventory (SXI). METHODS A cross-sectional, self-administered, electronic Arabic SXI was sent to 79 patients with thyroid nodules (female: n = 34, 57%; male: n = 45, 57%) who visited the Otolaryngology-Head and Neck Surgery clinic at King Abdulaziz University Hospital and King Fahad Medical City between June 2023 and July 2023. RESULTS Dependability was assessed using Cronbach's alpha coefficients at two distinct instances (first: α = 0.824, second: α = 0.932), which reaffirmed the SXI's reliability and consistency. Legitimacy was ascertained using a test-retest method and correlation analysis between the two measurements. CONCLUSION All SXI items displayed a potent positive correlation (between 0.746 and 0.871, p < 0.001), exhibiting remarkable consistency in responses over time. The outcomes of the paired t-tests showed nonsignificant differences for all queries, indicating that the responses were stable over time.

Abstract
The oral health of older individuals can be negatively impacted by various systemic health factors, leading to rapid oral health deterioration. This paper aims to present an overview of the published evidence on systemic health factors that contribute to rapid oral health deterioration in older individuals, and to explore the implications of these factors for both general healthcare and oral healthcare provision. Older people are at risk of experiencing adverse reactions to medications due to multimorbidity, polypharmacy, and changes in pharmacokinetics and pharmacodynamics. Hyposalivation, a significant side effect of some medications, can be induced by both the type and number of medications used. Frailty, disability, sarcopenia, care dependency, and limited access to professional oral healthcare can also compromise the oral health of older people. To prevent rapid oral health deterioration, a comprehensive approach is required that involves effective communication between oral healthcare providers, other healthcare providers, and informal caregivers. Oral healthcare providers have a responsibility to advocate for the importance of maintaining adequate oral health and to raise awareness of the serious consequences of weakened oral health. By doing so, we can prevent weakened oral health from becoming a geriatric syndrome.

Abstract
Salivary gland (SG) dysfunction, due to radiotherapy, disease, or aging, is a clinical manifestation that has the potential to cause severe oral and/or systemic diseases and compromise quality of life. Currently, the standard-of-care for this condition remains palliative. A variety of approaches have been employed to restore saliva production, but they have largely failed due to damage to both secretory cells and the extracellular matrix (niche). Transplantation of allogeneic cells from healthy donors has been suggested as a potential solution, but no definitive population of SG stem cells, capable of regenerating the gland, has been identified. Alternatively, mesenchymal stem cells (MSCs) are abundant, well characterized, and during SG development/homeostasis engage in signaling crosstalk with the SG epithelium. Further, the trans-differentiation potential of these cells and their ability to regenerate SG tissues have been demonstrated. However, recent findings suggest that the "immuno-privileged" status of allogeneic adult MSCs may not reflect their status post-transplantation. In contrast, autologous MSCs can be recovered from healthy tissues and do not present a challenge to the recipient's immune system. With recent advances in our ability to expand MSCs in vitro on tissue-specific matrices, autologous MSCs may offer a new therapeutic paradigm for restoration of SG function.

Abstract
Dysphagia has been classified as a “geriatric syndrome” and can lead to serious complications that result in a tremendous burden on population health and healthcare resources worldwide. A characteristic age-related change in swallowing is defined as “presbyphagia.” Medical imaging has shown some changes that seriously affect the safety and efficacy of swallowing. However, there is a general lack of awareness of the effects of aging on swallowing function and a belief that these changes are part of normal aging. Our review provides an overview of presbyphagia, which has been a neglected health problem for a long time. Attention and awareness of dysphagia in the elderly population should be strengthened, and targeted intervention measures should be actively implemented.

Tolerance to intraoral biofilms and their effectiveness in improving mouth dryness and modifying oral microbiota in patients with primary Sjögren's syndrome: "Predelfi study". Front Microbiol 2023; 14:1071683.

Abstract
INTRODUCTION Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease characterized by exocrine gland dysfunction. No therapeutic strategy is sufficient on its own for the management of dry mouth and therapeutic innovations are required. METHODS This Predelfi study was a single-center, prospective, comparative, randomized, double-blind, cross-over controlled study with the primary objective of assessing the tolerance to and effectiveness of two adhesive biofilms (containing prebiotics and, sodium alginate, respectively) in patients with pSS and hyposialia (#NCT04206826 in ClinicalTrials.gov). Secondary objectives were to obtain initial data regarding the clinical effectiveness of such biofilms in the improvement of signs and symptoms related to dry mouth and potential changes in the oral microbiota. Ten pSS patients with pSS were included (9 females and 1 male) with a mean age of 58.1 ± 14.0 years. RESULTS AND DISCUSSION Tolerance to the prebiotic and sodium alginate biofilms was assessed by the patients (visual analog scale [VAS] score 66.7 and 87.6, respectively) and the practitioner (90 and 100, respectively). The absolute changes in the VAS scores at the start and end of each treatment period highlighted an improvement in mouth dryness for the sodium alginate versus the prebiotic biofilm. The VAS scores for other parameters (mouth burning sensation; taste alteration; chewing; swallowing and speech difficulties) remained globally comparable between the two groups. Unstimulated salivary flow showed no changes regardless of the biofilm used. Regarding the oral microbiota, the sodium alginate biofilm increased the abundance of the Treponema genus, whereas the use of the prebiotic biofilm as the first treatment increased the abundance of the genera Veillonella and Prevotella. Nevertheless, the prebiotic biofilm appeared to stimulate "milder" genera with regard to periodontal infections. Furthermore, pre-treatment with the prebiotic biofilm prevented the emergence of the Treponema genus induced by subsequent treatment with the sodium alginate biofilm, suggesting a potential protective effect.

Abstract
OBJECTIVE Approximately 70% of the elderly population living in Yogyakarta, Indonesia, has a low oral health-related quality of life (OHRQoL). This study aimed to identify the risk factors for low OHRQoL in the elderly population of Yogyakarta. MATERIALS AND METHODS Oral Hygiene Index Simplified (OHI-S), Community Periodontal Index, Decayed, Missing, and Filled Teeth (DMFT) Index, and the number of natural occluding pairs (NOP) were assessed for 153 participants aged ≥ 60 years. Xerostomia, hyposalivation, and OHRQoL were also examined using Xerostomia Inventory (XI), unstimulated spitting whole saliva collecting method, and Geriatric Oral Health Assessment Index (GOHAI) questionnaire, respectively. OHRQoL was categorized as low, moderate, and high. STATISTICAL ANALYSIS Bivariate and multivariate tests were conducted to identify the risk factors for low OHRQoL. RESULTS Initial analysis of characteristics of participants revealed that hyposalivation, xerostomia, periodontal pocket, high DMFT, NOP ≤ 5, poor OHI-S, and low OHRQoL were experienced by 40 (26.1%), 92 (60.1%), 39 (25.5%), 110 (71.9%), 112 (73.2%), 44 (28.8%), and 108 (70.6%) participants, respectively. Relative risk (RR) and p values for hyposalivation, xerostomia, periodontal pocket, high DMFT, NOP ≤5, and poor OHI-S were found to be at 1.573 (CI 0.681-3.637) and 0.225; 2.532 (CI 1.255-5.108) and 0.006; 0.846 (CI 0.391-1.830) and 0.606; 1.759 (CI 0.843-3.670) and 0.110; 1.133 (CI 0.522-2.461) and 0.008; and 2.723 (CI 1.293-5.734) and 0.632, respectively. Multivariate tests showed that xerostomia and NOP ≤5 had RR of 2.519 (CI 1.221-5.195) and 2.536 (CI 1.175-5.477), respectively. CONCLUSIONS Overall, elders with xerostomia or NOP ≤ 5 had 2.5 times higher risk of having a low OHRQoL.

Abstract
The continuous sequence of bone healing phases starts off with osteoconduction to the implant surface, depending on the migration of osteogenic cells. Osteoneogenesis ensues resulting in a mineralised interfacial matrix and is followed by bone remodelling to the implant interface at discrete sites. Dental implant drilling procedure and placement produce osseous defect which is filled by blood. Within seconds, blood proteins are adsorbed onto the implant surface and platelets are activated resulting in the release of cytokines and growth factors. Further platelet aggregation initiates osteoconduction to the surface, followed by osteoneogenesis, forming an extracellular matrix. Subsequently, remodelling creates a bone to implant interface which can be explained through distance and contact osteogenesis. The dental implant surface has been shown to influence osteoconduction by modifying protein properties and adsorption around the implant. Salivary biomarkers may be considered as a specific and sensitive diagnostic tool to detect these changes in protein expressions after implant placement. Thus, the purpose of this narrative review is to provide a detailed account of the bone healing mechanism associated with dental implant placement, as well as how the implant surface architecture and protein release play a role in bone healing, and the potential use of saliva to detect these biomarkers.

Abstract
Electrogustometry (EGM) is one of the most useful diagnostic tools widely used to evaluate the taste function by measuring the perception threshold to electrogustatory stimuli on the tongue. However, the effects of oral environments on electrogustometric threshold (EGMT) remain to be established despite its simple applicability. Thus, this study aims to determine the effect of mucosal dryness on EGMT in 68 healthy subjects. The experiment was conducted in two different conditions. First, the baseline EGMT was measured when the dryness of the tongue surface was normal. Second, the EGMT was remeasured after the tongue was intentionally desiccated. The current study showed that the mean of the EGMT was significantly increased when the tongue was desiccated, possibly indicating the reduced sensitivity to electrogustatory stimuli. Such an alteration may be related to the disturbed EGM electrical circuit through the dried mucosa with enhanced impedance. Thus, these findings suggested that mucosal dryness should be considered for better evaluation of gustatory function using EGM.

Abstract
Mucin in saliva plays a critical role in the hydration and lubrication of the oral mucosa by retaining water molecules, and its impaired function may be associated with hyposalivation-independent xerostomia. Age-dependent effects on salivary gland function and rheological properties of secreted saliva are not fully understood as aging is a complex and multifactorial process. We aimed to evaluate age-related changes in the rheological properties of saliva and elucidate the underlying mechanism. We performed ex vivo submandibular gland (SMG) and sublingual gland (SLG) perfusion experiments to collect saliva from isolated glands of young (12 wk old) and aged (27 mo old) female C57BL/6J mice and investigate the rheological properties by determining the spinnbarkeit (viscoelasticity). While fluid secretion was comparable in SMG and SLG of both mice, spinnbarkeit showed a significant decrease in SLG saliva of aged mice than that of young mice. There were no significant differences in GalNAc concentration between young and aged SLG saliva. Liquid chromatography/tandem mass spectrometry analysis of SLG saliva revealed that (Hex)1 (HexNAc)1 (NeuAc)1 at m/z 793.31 was the most abundant O-glycan structure in SLG saliva commonly detected in both mice. Lectin staining of salivary gland tissue showed that SLG stained strongly with Maackia amurensis lectin II (MAL II) while Sambucus nigra agglutinin (SNA) stained little, if any, SLG. The messenger RNA expression of St3gal1 that encodes an α-2,3 sialic acid sialyltransferase SIAT4-A showed a decrease in SLG of aged mice, confirmed by a Western blot analysis. Lectin blot analysis in SLG saliva revealed that the relative signal intensity detected by MAL II was significantly lower in aged SLG. Our results suggest that spinnbarkeit decreases in SLG of aging mice due to downregulation of sialic acid linked to α-2,3 sialic acid sialyltransferase expression.

Abstract
The medical term xerostomia refers to the subjective sensation of oral dryness. The etiology seems to be multifactorial with the most frequently reported causes being the use of xerostomic medications, neck and head radiation, and systematic diseases (such as Sjögren’s syndrome). Xerostomia is associated with an increased incidence of dental caries, oral fungal infections, and difficulties in speaking and chewing/swallowing, which ultimately affect the oral health-related quality of life. The development of successful management schemes is regarded as a highly challenging project due to the complexity of saliva. This is why, in spite of the fact that there are therapeutic options aiming to improve salivary function, most management approaches are alleviation-oriented. In any case, polymers are an integral part of the various formulations used in every current treatment approach, especially in the saliva substitutes, due to their function as thickening and lubricating agents or, in the case of mucoadhesive polymers, their ability to prolong the treatment effect. In this context, the present review aims to scrutinize the literature and presents an overview of the role of various polymers (or copolymers) on either already commercially available formulations or novel drug delivery systems currently under research and development.

Regular Oral Health Management Improved Oral Function of Outpatients with Oral Hypofunction in Dental Hospital: A Longitudinal Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19042154. [PMID: 35206345 PMCID: PMC8871729 DOI: 10.3390/ijerph19042154] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/27/2021] [Revised: 02/08/2022] [Accepted: 02/09/2022] [Indexed: 02/05/2023]
Abstract
This longitudinal study aimed to clarify the impact of regular oral health management for oral hypofunction on the oral function of older dental outpatients. The 68 participants enrolled in this study were older dental outpatients (mean age 78.5 ± 8.1 years). According to the number of declined oral examinations after the first exam, participants were assigned to the oral hypofunction group (Hypo group, ≥3), receiving regular oral health management with a leaflet at the dental clinic, or the pre-oral hypofunction group (Pre-hypo group, ≤2), which served as a control. At the second oral examination, after approximately 6 months to 1 year, the Hypo group showed significant improvement in the tongue-lip motor function (Oral diadochokinesis, ODK) /pa/, /ta/, and masticatory function, while the Pre-hypo group showed significant worsening in oral hygiene and oral wetness. Temporal changes in ODK /pa/, /ta/, and the number of declined examination items were significantly different between the groups. Multiple analysis revealed that the number of improved oral examination items were associated with presence of regular oral health management after adjusting for age, sex, number of visits, measuring period, and dental treatment. Regular comprehensive oral health management for oral hypofunction improves and maintains oral function among older dental outpatients.

Abstract
OBJECTIVES Cheilitis Glandularis (CG) is an uncommon entity of obscure etiology. A cases series is presented with emphasis on etiopathogenesis. MATERIALS AND METHODS Fourteen CG cases were analyzed according to their demographic and clinicopathologic characteristics. RESULTS The mean age of the patients with CG was 68.1 years, while a male-to-female ratio of 1.8:1 was observed. One or more potential causative factors were identified for each patient, including long-term smoking (9 cases), xerostomia (4 cases), cosmetic filler injections (2 cases), and actinic cheilitis (1 case). The lesions were located on the lips, buccal mucosa, or both in 7, 2, and 5 cases, respectively. Multiple submucosal nodules with dilated ductal orifices and mucous or purulent discharge were observed in all cases. Histopathologically, ductal ectasia with metaplasia, intraductal mucin, and chronic or mixed inflammation were noted, as well as pools of hyaluronic acid in 2 cases with a history of cosmetic filler injections. CONCLUSIONS CG etiopathogenesis is probably multifactorial. Reduced salivary flow rate and increased viscosity of saliva, potentially caused by long-term smoking, diabetes mellitus, and drug-induced xerostomia, may participate in the initial pathogenesis, while local irritants, for example, poor oral hygiene and local trauma, may further contribute to the development and aggravation of the condition.

Abstract
BACKGROUND There is no recent information about dental service utilization (DSU) among elderly in Lithuania. We examined DSU and its associated factors in Lithuanian early elderly based on the Andersen's behavioural model. METHODS The cross-sectional study conducted in 2017-2019 included a nationally representative stratified sample of 370 Lithuanian early elderly aged 65-74 years (response rate of 54.5%). Information on predisposing factors (age, sex, nationality and education), enabling factor (residence), need-based factors (status of teeth, oral pain or discomfort, and dry mouth), general health, personal health practices and perceived stress was obtained from a structured, self-administered questionnaire. Clinically-assessed need-based factors included number of missing teeth and dental treatment need. Multivariable Poisson regression with robust variance estimates was used. RESULTS A total of 239 study participants (64.6%) reported a dental visit during the last year and 338 (91.4%) needed dental treatments. A higher level of education (adjusted prevalence ratio [aPR] = 1.21, 95% confidence interval [CI]:1.04-1.40), pain or discomfort in teeth/mouth (aPR = 1.35, 95%CI: 1.13-1.62) and lower number of missing teeth (aPR = 0.99, 95%CI: 0.98-1.00) were associated with DSU. CONCLUSIONS Even though majority of early elderly needed dental treatments, only two-thirds visited a dentist during the last year. Predisposing and need-based factors were significant predictors of having a dental visit in the last year. A national oral health program for Lithuanian elderly with the focus on regular preventive dental check-ups is needed. More studies, both quantitative and qualitative, are warranted to investigate in depth the barriers for DSU among elderly in Lithuania.

Abstract
The researchers' aims were to evaluate the effects of chokeberry juice in the treatment of burning mouth syndrome (BMS) and oral discomfort in menopausal women. The following validated scales and questionnaires were used before and after treatment: questionnaire used for selection of research participants with xerostomia, the xerostomia inventory, Visual Analogue Scale (VAS), localization of pain before and after treatment, short-form McGill pain questionnaire. There was statistically significant decrease in number of research participants who felt pain after therapeutic procedure (p < 0.05). Chokeberry juice, as additional therapy for BMS, reduced intensity of characteristic types of pain sensations and oral dryness feeling.

Abstract
BACKGROUND oral frailty (OFr) may be called a syndrome lacking a consensus on its definition. OBJECTIVE the aim was to prove the relationship between OFr to the phenotype of frailty, general health and nutrition in long-term care. DESIGN the FINnish ORAL Health Study in Long-Term Care study is a cross-sectional clinical research comprising findings on oral and general health and nutrition. SETTING participants were divided into groups according to the number of OFr signs: Group 1 (0-1 sign), Group 2 (2-4 signs) and Group 3 (5-6 signs). SUBJECTS the study includes data on 349 older residents of long-term care facilities in Helsinki, Finland. METHODS frailty status was defined according to Fried's frailty phenotype. OFr was evaluated with six signs: dry mouth, diet of pureed or soft food, residue of food on oral surfaces, unclear speech, inability to keep mouth open during the clinical oral examination and pain expression during the examination. RESULTS a significant linear relationship across the OFr groups with Fried's frailty phenotype was found (P for linearity = 0.008, adjusted by gender and age). A linear trend existed between OFr groups and general health; prevalence of dementia and malnutrition increased from Group 1 to Group 3. The need for help with eating and oral hygiene procedures increased from Group 1 to Group 3. Moreover, OFr had a linear relationship with chewing and swallowing difficulties. CONCLUSIONS OFr is related to Fried's frailty phenotype, general health, nutrition and need for help with daily activities.

Abstract
Nutritional status is a series of related parameters collected using different available methods. In order to determine the nutritional status of elderly populations and ensure nutritional support based on an individual approach, the implementation of the increasingly used foodomics approach is available; this approach plays a key role in personalized diets and in the optimization of diets for a population group, such as an elderly population. The Mini Nutritional Assessment (MNA) method and the Nottingham Screening Tool (NST) form were used on 50 users in a home for the elderly in northwest Croatia. A loss of body mass (BM) was statistically significantly higher for those who had the following: decreased food intake in the last week and users who had complete and partial feeding autonomy. Additionally, the obtained data on drug intake, fluid, individual nutrients, and physical activity are based on an individual approach. The available documentation provides insight into nutritional values and food preparation in an attempt to satisfy a holistic approach in the evaluation of exposure while trying to achieve as many elements of foodomics as possible.

Abstract
OBJECTIVE Salivary glands are among the most sensitive target organs of medications with anticholinergic (AC) properties, interrupting the neural stimulation of saliva secretion and reducing saliva flow. Hyposalivation results in dry mouth, leading to dental caries, intraoral infection, orofacial pain, problems with speaking and swallowing, and diminished oral health--related quality of life. Current understanding of the pharmacokinetics of AC medications and their effect on muscarinic receptors in the salivary glands were reviewed to assist clinicians in predicting salivary damage in patients with AC medication-induced dry mouth. STUDY DESIGN We summarized the literature related to the mechanisms and properties of AC medications, anticholinergic adverse effects, and their effect on salivary function and management strategies to prevent oral health damage. RESULTS Although a large number of studies reported on the frequencies of medication-induced dry mouth, we found very limited data on predicting individual susceptibility to AC medication--caused hyposalivation and no prospective clinical studies addressing this issue. CONCLUSION Dry mouth is most frequently caused by medications with AC properties, which interrupt the neural stimulation of saliva secretion. Interdisciplinary care should guide pharmacotherapeutics and dental interventions should aim in preventing AC salivary adverse effects and reducing the oral health burden from AC medication-induced dry mouth.

Abstract
The number of elderly multiple sclerosis (MS) patients is growing, mainly due to the increase in the life expectancy of the general population and the availability of effective disease-modifying treatments. However, current treatments reduce the frequency of relapses and slow the progression of the disease, but they cannot stop the disability accumulation associated with disease progression. One possible explanation is the impact of immunosenescence, which is associated with the accumulation of unusual immune cell subsets that are thought to have a role in the development of an early ageing process in autoimmunity. Here, we provide a recent overview of how senescence affects immune cell function and how it is involved in the pathogenesis of autoimmune diseases, particularly MS. Numerous studies have demonstrated age-related immune changes in experimental autoimmune encephalomyelitis models, and the premature onset of immunosenescence has been demonstrated in MS patients. Therefore, potential therapeutic strategies based on rejuvenating the immune system have been proposed. Senolytics and regenerative strategies using haematopoietic stem cells, therapies based on rejuvenating oligodendrocyte precursor cells, microglia and monocytes, thymus cells and senescent B and T cells are capable of reversing the process of immunosenescence and could have a beneficial impact on the progression of MS.

Abstract
BACKGROUND Discomfort encountered during oral processing may cause food avoidance and increase the risk of malnutrition in older adults. The aim of the present survey was to explore the relationships between oral health and the oral discomfort experienced while eating in senior people. MATERIALS AND METHODS In a cross-sectional study, oral discomfort was assessed in a sample of 119 independently living participants aged between 35 and 81 years. Statistical analyses were used to identify categorical variables associated with food-related oral discomfort, including age, oral health-related quality of life (OHQoL), saliva secretion, occluding support, oral diseases and denture use. RESULTS Food-related oral discomfort concerned 28.5% of the participants. Within the sample study, the risk of experiencing food-related oral discomfort was increased for participants perceiving average (OR = 7.968, CI 95% = 2.603-24.381, p = .000) or poor OHQoL (OR = 17.109, CI 95% = 4.398-66.552, p = .000) and presenting strictly fewer than 7 occlusal functional units (OFUs) (OR = 3.396, CI 95% = 1.206-9.561, p = .020). Textured foods including fibrous (66.6%), heterogenous (60.6%) and grainy foods (42.4%) were mostly cited as food-related oral discomfort trigger factors. Within the 66-80 years group, participants having 0-6 OFUs were four times more likely to experience oral discomfort related to fibrous foods than participants having more than 7 OFUs (OR = 4.812, CI 95% = 1.192-19.415, p = .024). Within this group, participants having their teeth replaced by denture were also four times more likely to develop oral discomfort related to foods with heterogeneous textures (OR = 4.714, CI 95% = 1.030-21.562, p = .045) and grainy foods (OR = 7.285, CI 95% = 1.308-40.568, p = .023) than non-denture wearers. CONCLUSION Poor oral health conditions may generate oral discomfort with foods in the elderly especially with fibrous, heterogenous and grainy textures, and thus affect mealtime experience.

Abstract
The past decade has seen marked increases in research findings identifying oral-systemic links. Yet, much of dental research remains poorly integrated with mainstream biomedical research. The historic separation of dentistry from medicine has led to siloed approaches in education, research and practice, ultimately depriving patients, providers, and policy makers of findings that could benefit overall health and well-being. These omissions amount to lost opportunities for risk assessment, diagnosis, early intervention and prevention of disease, increasing cost and contributing to a fragmented and inefficient healthcare delivery system. This perspective provides examples where fostering interprofessional research collaborations has advanced scientific understanding and yielded clinical benefits. In contrast are examples where failure to include dental research findings has limited progress and led to adverse health outcomes. The impetus to overcome the dental-medical research divide gains further urgency today in light of the coronavirus pandemic where contributions that dental research can make to understanding the pathophysiology of the SARS-CoV-2 virus and in diagnosing and preventing infection are described. Eliminating the research divide will require collaborative and trans-disciplinary research to ensure incorporation of dental research findings in broad areas of biomedical research. Enhanced communication, including interoperable dental/medical electronic health records and educational efforts will be needed so that the public, health care providers, researchers, professional schools, organizations, and policymakers can fully utilize oral health scientific information to meet the overall health needs of the public.

The effect of fibroblast growth factor 7 on human dental pulp stem cells for differentiation to AQP5-positive and αSMA-positive cells in vitro and in vivo. Clin Exp Dent Res 2021; 7:344-353. [PMID: 33783980 PMCID: PMC8204033 DOI: 10.1002/cre2.423] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Revised: 02/27/2021] [Accepted: 03/02/2021] [Indexed: 01/29/2023] Open
Abstract
OBJECTIVES Transplantation of stem cells into wounds has become popular in regeneration therapies. As stem cells for transplantation, human dental pulp stem cells (hDPSCs) are known to be pluripotent cells that are relatively easy to collect from the pulp of deciduous or wisdom teeth. The purpose of this study was to investigate whether hDPSCs treated with fibroblast growth factor 7 (FGF7) would contribute to the regeneration of wounded rat submandibular glands (SMGs). MATERIALS AND METHODS In in vitro studies, hDPSCs were treated with or without FGF7 and mRNA expression levels were examined at days 3, 7 and 14 using qRT-PCR. The target genes analyzed were BMI1 as an undifferentiated marker, AQP5 as an acinar cell marker, CK19 as a ductal epithelial cell marker, αSMA as a myoepithelial cell marker and VIMENTIN as a fibroblast marker. In in vivo studies, hDPSCs treated with or without FGF7 for 14 days were mixed with type I collagen gels and were transplanted into wounded rat SMGs. Hematoxylin-Eosin and immunohistochemical staining were performed at days 3 and 7, and the numbers of positive cells were counted. The primary antibodies used were against BMI1, AQP5, αSMA, PanCK and VIMENTIN. RESULTS In the in vitro studies, mRNA levels of BMI1 were decreased and αSMA were increased at days 3, 7 and 14, while AQP5 was increased at day 14 in the FGF7 group. In the in vivo studies, the proliferation of hDPSCs and cell islands was observed at day 7 in the FGF7 group. Few BMI1-positive cells were observed, while numbers of AQP5-positive and αSMA-positive cells were increased at days 3 and 7 in the FGF7 group. Moreover, cell islands were AQP5-positive. CONCLUSION These results suggest that FGF7-treated hDPSCs differentiate into AQP5-positive and αSMA-positive cells. Moreover, AQP5-positive cell aggregations were formed.

Beyond dissolution: Xerostomia rinses affect composition and structure of biomimetic dental mineral in vitro. PLoS One 2021; 16:e0250822.

Abstract
Xerostomia, known as dry mouth, is caused by decreased salivary flow. Treatment with lubricating oral rinses provides temporary relief of dry mouth discomfort; however, it remains unclear how their composition affects mineralized dental tissues. Therefore, the objective of this study was to analyze the effects of common components in xerostomia oral rinses on biomimetic apatite with varying carbonate contents. Carbonated apatite was synthesized and exposed to one of the following solutions for 72 hours at varying pHs: water-based, phosphorus-containing (PBS), mucin-like containing (MLC), or fluoride-containing (FC) solutions. Post-exposure results indicated that apatite mass decreased irrespective of pH and solution composition, while solution buffering was pH dependent. Raman and X-ray diffraction analysis showed that the addition of phosphorus, mucin-like molecules, and fluoride in solution decreases mineral carbonate levels and changed the lattice spacing and crystallinity of bioapatite, indicative of dissolution/recrystallization processes. The mineral recrystallized into a less-carbonated apatite in the PBS and MLC solutions, and into fluorapatite in FC. Tap water did not affect the apatite lattice structure suggesting formation of a labile carbonate surface layer on apatite. These results reveal that solution composition can have varied and complex effects on dental mineral beyond dissolution, which can have long term consequences on mineral solubility and mechanics. Therefore, clinicians should consider these factors when advising treatments for xerostomia patients.

Abstract
Purpose Traditionally, etiology of dysphagia is thought to be related to multiple medical diagnoses including stroke, head and neck cancer, degenerative neurological conditions, and so forth. However, community dwelling older adults (CDOA) can present with dysphagia in the absence of any specific etiology. The purpose of this research was to develop a multidimensional framework to help identify those CDOA at risk for dysphagia of nonspecific etiology. Method Pertinent literature was examined to identify support for the proposed framework and to explain how the various elements support the model. Results Several factors that are not traditionally thought to be associated with dysphagia can both initiate and exacerbate symptoms of swallowing difficulties. Swallowing difficulties may be subtle and underreported. Monitoring for symptoms related to preclinical dysphagia may be helpful for early identification. Conclusions Dysphagia in CDOA is complex and multidimensional. Clinicians working with older adults will benefit from considering elements described in this multidimensional framework to better understand the etiology of swallowing deficits and improve management.

Abstract
In this review, the author shows that simultaneous multiple disorders caused by reactivation of Epstein-Barr virus can lead to salivary gland disorders as part of Sjogren's syndrome (SS). Therefore, clinicians must differentiate SS from other diseases when diagnosing and treating salivary gland disorders. In particular, the author explains how microbial infection in SS overcomes immunological tolerance, leading to pathological changes, and how cytokine overexpression and endocrine disrupters contribute to glandular tissue injury. Also, the author suggests that involvement of reactive oxygen species is a common pathogenesis of salivary gland disorders and SS, so regulation of oxidative stress is an effective treatment for both. The results of clinical studies on restoring salivary gland function and regenerating salivary glands with tissue stem cells may provide clues on elucidating the cause of SS.

Pathways to help-seeking for sexual difficulties in older adults: qualitative findings from the third National Survey of Sexual Attitudes and Lifestyles (Natsal-3). Age Ageing 2021; 50:546-553.

Abstract
BACKGROUND Older adults are at an increased risk of sexual difficulties due to ageing and chronic health conditions. While they experience barriers to seeking and receiving help for sexual difficulties there is a dearth of research about the help-seeking journey. OBJECTIVE To explore decision-making in context; particularly, the reasons why older adults do, or do not, seek help for sexual difficulties. METHODS Semi-structured interviews were conducted with 11 men and 12 women aged 58-75 who reported having a health condition, disability or medication that had affected their sex life in the last year. Participants were part of the third British National Survey of Sexual Attitudes and Lifestyles (Natsal-3). Data were analysed thematically. RESULTS Help-seeking was rarely a predictable or linear process. Participants tended to wait and see if the sexual difficulty got better on its own or improved as a result of lifestyle changes. An often-lengthy period of thinking, researching and planning could end with a decision to seek professional help, to not seek help, or do nothing for now. A significant barrier was concern about the interaction of medicines prescribed for the sexual difficulty with those already taken for chronic health conditions. Patient fear of not being taken seriously and doctor reticence to ask thwarted potential conversations. Help-seeking journeys often ended without resolution, even when professional help was sought. CONCLUSIONS To give patients and practitioners permission to raise the topic, suggestions include providing patients with a pre-consultation card which lists topics they would like to talk about, including sexual issues.

Therapeutic Recommendations for the Management of Older Adult Patients with Sjögren's Syndrome. Drugs Aging 2021; 38:265-284.

Abstract
Primary Sjögren's syndrome (SjS) is a systemic autoimmune disease most commonly diagnosed in middle-aged women. Although the disease can occur at all ages, it is diagnosed between 30 and 60 years of age in two-thirds of patients. In more than 20% of cases, the people are older than 65 years. In this review, we focus on the therapeutic management of primary SjS in older patients, following the recently published 2020 European League Against Rheumatism (EULAR) recommendations for the management of the disease with topical and systemic therapies. These recommendations are applicable to all patients with primary SjS regardless of age at diagnosis, although the therapeutic management in older patients requires additional considerations. Older patients are more likely to have pulmonary, liver, kidney, or heart-related comorbidities (even cognitive disturbances); caution is required when most drugs are used, including muscarinic agents, systemic corticosteroids and synthetic immunosuppressants. It is also important to monitor the use of eye drops containing steroids due to the increased risk of developing cataracts, a frequent ocular complication in the older population. In contrast, the majority of drugs that can be used topically (pilocarpine rinses, eye drops containing topical non-steroidal anti-inflammatory drugs (NSAIDs) or cyclosporine A, topical dermal formulations of NSAIDs) have shown an acceptable safety profile in older patients, as well as rituximab. A rigorous evaluation of the medical history of older patients is essential when drugs included in the EULAR guidelines are prescribed, with special attention to factors frequently related to ageing, such as polypharmacy, the existence of organ-specific comorbidities, or the enhanced susceptibility to infections.

Abstract
The understanding of friction on soft sliding biological surfaces at the nanoscale is poorly understood as hard interfaces are frequently used as model systems. Herein, we studied the influence of elastic modulus on the frictional properties of model surfaces at the nanoscale for the first time. We prepared model silicone-based elastomer surfaces with tuneable modulus ranging from hundreds of kPa to a few MPa, similar to those found in real biological surfaces, and employed atomic force microscopy to characterize their modulus, adhesion, and surface morphology. Consequently, we used friction force microscopy to investigate nanoscale friction in hard-soft and soft-soft contacts using spherical colloidal probes covered by adsorbed protein films. Unprecedented results from this study reveal that modulus of a surface can have a significant impact on the frictional properties of protein-coated surfaces with higher deformability leading to lower contact pressure and, consequently, decreased friction. These important results pave the way forward for designing new functional surfaces for serving as models of appropriate deformability to replicate the mechanical properties of the biological structures and processes for accurate friction measurements at nanoscale.

Abstract
OBJECTIVE To evaluate the impact of an online oral health education module on personal support workers' (PSW) knowledge and beliefs in their care for long-term care (LTC) residents in one Canadian LTC residence. BACKGROUND LTC residents are dependent on PSWs for their oral health needs. However, PSWs receive minimal to no oral health education placing residents at risk for poor oral health. METHODS A mixed-methods convergent design comprising a before-and-after questionnaire (N = 88), focus groups (N = 23) and interviews (N = 4) exploring module learning. Analysis of each data set was followed by their amalgamation and comparison. RESULTS The online module had limited impact on the PSWs' knowledge and beliefs regarding resident oral health care. The quantitative results demonstrated knowledge improvements in two domains and changes in two belief domains. However, the qualitative results demonstrated new knowledge was not developed or sustained in practice. Themes that emerged include the following: lack of module recall, unmet learning needs and methods for oral care delivery, and timing of oral care in a busy clinical environment. CONCLUSION Online oral health education alone has limited impact on PSWs' knowledge and beliefs. Research evaluating multifaceted education interventions including hands-on training with a dental expert is warranted.

Abstract
There is an increasing interest in using saliva to measure inflammatory biomarkers. Compared to blood, saliva is non-invasive, requires a lower biosafety classification, and requires less specialized personnel to collect. As the assessment of inflammation in saliva becomes more popular in psychoneuroimmunology research, the development of gold-standard methodological practices is paramount. This paper reviews different considerations for designing studies to assess salivary measures of inflammation. We review saliva collection procedures, sample storage and processing considerations, assay techniques, flow rate, correspondence with blood-based markers, and potential demographic and health moderators of levels of salivary markers of inflammation. Together, this review highlights critical gaps for future research, including calls for standardization of study protocols, transparent reporting of results, assessing predictive validity of markers of salivary inflammation for disease, and the need for assessment of participants' oral and general health status. Although additional work is needed to elucidate gold standards for study design, measurement, and analysis, salivary markers of inflammation may be a useful tool for understanding oral and peripheral inflammation dynamics non-invasively.

Abstract
The aim of this review is to assess the objective and subjective diagnosis, as well as symptomatic topical treatment of dry mouth conditions with a clear focus on textural perspective. We critically examine both the current practices as well as outline emerging possibilities in dry mouth diagnosis and treatment, including a patent scan for saliva substitutes. For diagnosis, salivary flow rates and patient-completed questionnaires have proven to be useful tools in clinical practice. To date, objective measurements of changes in mechanical properties of saliva via rheological, adsorption, and tribological measurements and biochemical properties of saliva such as assessing protein, mucins (MUC5B) are seldom incorporated into clinical diagnostics; these robust diagnostic tools have been largely restricted to application in non-clinical settings. As for symptomatic treatments of dry mouth, four key agents including lubricating, thickening, adhesive, and moisturizing agents have been identified covering the overall landscape of commercial saliva substitutes. Although thickening agents such as modified celluloses, polysaccharide gum, polyethylene glycol, and so forth are most commonly employed saliva substitutes, they offer short-lived relief from dry mouth and generally do not provide boundary lubrication properties of real human saliva. Innovative technologies such as self-assembly, emulsion, liposomes, and microgels are emerging as novel saliva substitutes hold promise for alternative approaches for efficient moistening and lubrication of the oral mucosa. Their adoption into clinical practice will depend on their efficacies, duration of relief, and ease of application by the practitioners and patient compliance.

Abstract
The objective was to explore the effectiveness of photobiomodulation therapy for treating patients who suffer xerostomia and/or hyposalivation due to the most prevalent clinical diagnoses. We searched PubMed, Scopus, Web of Science, CINAHL and Cochrane Library for randomized or clinical controlled trials published until 31 October 2019. Risk of bias assessment and meta-analysis were conducted using the Cochrane tools. A total of 274 records were retrieved, and 11 met the inclusion criteria. Interventions whose parameters ranged between wavelengths of 790-830 nm (infrared), 30-120 mW of power and an energy density below 30 J/cm-2 were associated with improvements in xerostomia/hyposalivation. As for the assessment of methodological quality, 10 of the 11 articles included had a high risk of overall bias. Only 3 articles provided sufficient information to conduct a meta-analysis for quality of life, compared with placebo in patients with burning mouth syndrome, showing a standardized mean difference between groups from baseline of -0.90 (-1.48; -0.32). The present review and meta-analysis suggest that photobiomodulation therapy is an effective, non-invasive and safe approach in patients with xerostomia. However, despite the potential, it is not possible to reach a reliable consensus on the parameters to be used, and future studies should be conducted by standardizing intervention protocols.

Abstract
With the projected increase to 1.3 billion people aged 65 years or older by 2040, healthcare professionals are faced with significant challenges in managing this population of patients. In the oral cavity, oral mucosal disease is a significant problem found in older populations. Several facial pain conditions are more likely to be seen in this cohort of patients. Although management of this group of patients may not always be appropriate in general practice, an awareness of the range of oral medicine conditions that may be encountered in older patients is essential to allow prompt referral and treatment.

Abstract
In this study, we evaluated the reliability and reproducibility of widely implemented salivary flow rate and oral dryness tests. In experiment 1, twenty young and healthy Japanese participants volunteered to participate. For each participant, the oral moisture (OM) level, unstimulated whole saliva volume (U-WSV), and stimulated whole saliva volume (S-WSV) were measured at the same time on two separate days. In experiment 2, twenty-seven patients who were over 65 years of age volunteered to participate. The OM level and U-WSV were measured at the same time on two separate days. In Experiment 1, the intra-class correlation coefficients (ICCs) corresponding to the S-WSV, U-WSV, and OM level were 0.23, 0.28, and 0.16, respectively, for the young participants. In Experiment 2, the ICCs corresponding to the U-WSV/spitting and OM level were 0.83 and 0.12, respectively, for the older participants. The results of Bland–Altman analysis confirmed the absence of systematic error, with the exception of the OM level results in Experiment 2, which indicated systematic bias. In conclusion, we believe that there is currently no consistent and reliable screening test for assessing salivary flow rate and oral dryness, although the spitting test was determined to be highly reliable.

Abstract
Background: Diabetes mellitus represents a group of metabolic diseases that are characterised by hyperglycaemia due to a total or relative lack of insulin secretion and insulin resistance or both. Diabetes mellitus patients present with a higher susceptibility to infections due to a deficiency in polymorphonuclear leukocytes, as a result of vascular alterations and neuropathies. An increased risk of infections has been observed in complete denture wearing subjects with xerostomia. The objective of this study was to compare diabetic and non-diabetic subjects wearing complete dentures regarding xerostomia of different age group. Materials and Methods: A cross-sectional study was conducted among 50 subjects, 25 with and 25 without a diagnosis of diabetes, were matched for gender, race, and age. Results: In this study we intended to compare diabetic and non-diabetic subjects wearing complete dentures regarding xerostomia and we found that xerostomia was more associated with diabetic denture wearer group in comparison with the non-diabetic denture wearers with a significant P value of <0.05. Conclusion: These results indicate that xerostomia should be diagnosed and effectively managed before any complete denture therapy is initiated in diabetic denture wearing patients to improve the quality of life.

Abstract
Purpose Self-selection and self-avoidance of certain foods is one possible indicator of preclinical (prior to any clinical intervention) dysphagia in healthy older adults. Self-selection of food choices is influenced by changes in a combination of factors, including neuromuscular, sensory, and individual patient characteristics. Changes to these factors occur both centrally or peripherally and can be part of typical, healthy aging. Alterations in motor, sensory, or cognitive skills may lead to self-imposed modifications to food choices and, therefore, highlight potential risk for dysphagia. Conclusions For effective screening and assessments procedures in healthy aging adults, the diagnosis of preclinical dysphagia will likely require a multifaceted assessment. A combination of assessment methods using objective and subjective measurements of neuromuscular, sensory, and individual patient factors, as well as knowledge of food avoidance, may provide insight for identifying community-dwelling older adults at risk for dysphagia and allow for earlier monitoring and intervention.

Abstract
Aging impairs senses, mastication, oral status and function, causing nutritional needs and diet insufficiencies. The present needs of independent older adults suggest that health research and oral health care should shift from reductionist disease management to integral and personal treatment plans, including lifestyle, psychological, nutritional and oral health coaching approaches. Dentists and other medical professionals that work in the field of gerodontology should be educated on the macro and micronutrient needs of the elderly and incorporate certain nutritional plans early in the life of their patients with their approval and cooperation, in order to postpone tooth loss and masticatory impairment. Old recipes such as the Mediterranean diet should be kept as a base for all the elderly and be enriched in a customized interpersonal way from the dentist as well as the medical professional according to the specific needs of one's oral and general health status. In this nonsystematic review paper, the basic aspects of the vicious cycle of nutrition and oral health status are discussed and suggestions of major nutrients' influence and needs for independent elders are reported. Based on the scientific data collected, suggestions are made for the food industry for better quality and dosage of foods for this category of individuals. Such strategies can be a whole new area of interest for the food industry in order to obtain better quality of food packaging for the independent OA with accepted texture, odor, colors, macronutrients and micronutrients' consistency and in specific portions.

Abstract
Bolus texture is a key factor for safe swallowing in patients with dysphagia since an improper texture may result in aspiration and/or pharyngeal residue. This article discusses swallowing bolus texture from two key aspects: the textural change of solid food by mastication and the current standardized definition of food texture in Japan. When swallowing a liquid bolus, the texture is mostly maintained from ingestion to swallow onset. For solid food, however, the food is crushed by chewing and mixed with saliva before swallowing; the texture of the ingested food is modified to an easily swallowable form at swallow onset by mastication. Understanding the mechanism of mastication and its assessment are therefore important in deciding the proper diet for dysphagic patients. As standardized criteria for classifying the texture of food and liquid are essential as well, this report also describes the Japanese Dysphagia Diet 2013 that is commonly used as the standardized index for dysphagic diets in Japan.

Abstract
Objective: The aim was to study prevalence of xerostomia, hyposalivation and quality of life among caries active younger adults.Materials and methods: A questionnaire regarding oral and general health, xerostomia and quality of life was mailed to 134 caries active (CA) and 40 caries inactive (CI) patients, 25-50 years of age (mean age 39.9 ± 6.2 years) treated at a Swedish Public Dental Service clinic, regarding oral and general health, xerostomia and quality of life. Caries data and unstimulated whole salivary flow rates were obtained from dental records.Results: The overall response rate was 69%. Dental records confirmed that CA patients had more decayed teeth over time than CI patients (p < .001). The CA group reported worse oral health (p < .001) and general health (p < .01), more xerostomia (p < .001) and lower salivary flow rate (p < .01) compared to CI patients. Xerostomia was inversely related to unstimulated whole salivary flow rates as well as to oral and general health (p < .01). There were no differences between groups in quality of life.Conclusion: Younger caries active adult patients reported significantly more xerostomia and hyposalivation compared to caries inactive patients. Xerostomia and hyposalivation were inversely related to perceptions of oral and general health, but not to quality of life.

Abstract
In this decade, substantial progress in the fields of developmental biology and stem cell biology has ushered in a new era for three-dimensional organ regenerative therapy. The emergence of novel three-dimensional cell manipulation technologies enables the effective mimicking of embryonic organ germ formation using the fate-determined organ-inductive potential of epithelial and mesenchymal stem cells. This advance shows great potential for the regeneration of functional organs with substitution of complete original function in situ. Organoids generated from multipotent stem cells or tissue stem cells via establishment of an organ-forming field can only partially recover original organ function owing to the size limitation; they are considered ‘mini-organs’. Nevertheless, they hold great promise to realize regenerative medicine. In particular, regeneration of a functional salivary gland and an integumentary organ system by orthotopic and heterotopic implantation of organoids clearly points to the future direction of organ regeneration research. In this review, we describe multiple strategies and recent progress in regenerating functional three-dimensional organs, focusing on ectodermal organs, and discuss their potential and future directions to achieve organ replacement therapy as a next-generation regenerative medicine.

Abstract
BACKGROUND Poor recognition of medicine-induced dry mouth can have a number of adverse effects, including difficulties with speech, chewing and swallowing dry foods, gum disease, dental caries and oral candidosis. This study examined the prevalence of use of medicines that cause dry mouth and claims for dental services funded by the Department of Veterans' Affairs (DVA) in an Australian cohort. METHODS We used the DVA administrative health claims data to identify persons using medicines that can cause dry mouth at 1st of September 2016 and determine their DVA dental claims in the subsequent year. Results were stratified by gender, residence in community or residential aged cared facility and number of medicines. RESULTS We identified 50 679 persons using medicines known to cause dry mouth. Of these, 72.6% were taking only one medicine that may cause dry mouth, and 21.6% were taking two. Less than half (46.2%) of all people taking at least one of these medicines had a dental claim in the following year. A smaller proportion of women (35.9%) made claims than men (56.9%), χ2 = 2248.77, P < 0.0001. CONCLUSIONS Targeted interventions raising awareness of the relationship between some medicines and dry mouth, and the importance of dental visits are warranted.

Abstract
OBJECTIVE This study aimed to assess the relationship between oral hygiene/stomatognathic function and residual intraoral medication in older adults and to identify the oral factors associated with residual oral medication. METHODS The study included 309 older adults (77 men, 232 women, mean age: 74.1 ± 7.4 years) who were prescribed medications at regular intervals. The following survey items were assessed: overall physical condition, intraoral condition and oral function. Participants prescribed oral medication were classified into groups with and without residual medication in the oral cavity. Statistical analysis was performed using univariate analysis for each of the factors contributing to the presence of residual medication. RESULTS Only 1.9% of all patients had residual medication, which suggests that older adults in this survey had a low risk of residual intraoral medication. However, greater attention should be given to residual intraoral medication in older adults receiving long-term care. Powdered-form oral medications were more likely to remain in the oral cavity. Older adults with residual medication had a tendency to have less occlusal support, poor tongue hygiene and poor tongue movement. Oral function, particularly functions that are closely related to swallowing, was significantly lower in the residual intraoral medication group when compared to those of the group without residual intraoral medication. CONCLUSIONS Reduced oral function and powered medication were associated with greater residual intraoral medication in this sample of older Japanese adults.

Abstract
Background. The world population is aging. This phenomenon is accompanied by an increase in the number of elderly with dementia, whose oral hygiene care is a challenge. Objective. This paper presents a literature review of oral health status and the need for oral care in people with dementia, as compared to people without dementia and also of the relationship between periodontal disease and cognitive impairment. Methods. A systematic review was conducted in PubMed, CINAHL, and the Cochrane Library. Fifty-six articles met the inclusion criteria and were consequently included for quality assessment and data extraction. Results. No significant differences were found between both groups with regard to the number of present teeth, DMFT Index, edentulousness/use of denture, and orofacial pain. Coronal/root caries and retained roots were more common in people with dementia than in those without dementia. Most of the participants with dementia presented gingival bleeding or inflammation and they suffered from the periodontal disease more than people without dementia. Conclusions. Poor oral health is a common condition among the elderly with dementia. The education process of caregivers might improve the oral health status of people with dementia. Finally, periodontal disease might contribute to the onset or progression of dementia.
