Food Typologies and Multidimensional Phenotyping of Elderly in Auvergne-Rhône-Alpes (Part'AGE)

To better understand how diet influences health during aging, the French National Research Institute for Agriculture, Food and the Environment (INRAE) is working with the Gérontopôle Auvergne-Rhône-Alpes on a project called Part'AGE. Part'AGE is a participatory research project where researchers want to recruit 1,000 people aged between 55 and 75 years, men and women, living in Auvergne-Rhône-Alpes in urban or rural areas. The goal is to study eating habits and state of health. To do this, researchers will examine many factors that can influence them, such as physical activity, overall health, consumption patterns or territories. Researchers will collect detailed information to classify participants into different groups (food typologies) based on their eating habits and state of health. With this distribution, the goal is to be able to give each group personalized nutritional advice to age in better health. To participate in the study, the participants will need to collect a few drops of blood from the end of the finger, a urine sample, and do some tests (mobility, oral health). It will also be necessary to fill out questionnaires on eating habits, physical activity, and other aspects that may influence health. The benefices for to participants will be to contribute to nutrition research and to receive personalized feedback and advices on eating habits.

Egyptian Dental Professionals' Perspectives on the Oral Microbiome and Exosomes

This study employs a structured, validated questionnaire as the index test to objectively assess dental professionals' knowledge of the oral microbiome and exosomes, alongside attitudes, readiness, and perceived barriers. The primary aim is to develop and compare Microbiome Knowledge Scores (MKS) and Exosome Knowledge Scores (EKS) across dental specialties, workplace settings, and years of practice. Secondary aims include evaluating attitudes and perceived barriers, assessing the relationship between self-rated and objective knowledge, and identifying predictors of higher knowledge levels. The study tests the null hypotheses that MKS/EKS do not differ across demographic or practice characteristics and that self-rated knowledge does not correlate with objective knowledge.

The main questions this research aims to answer are: What is the level of oral health knowledge among pregnant women attending Hospital La Fe? Does a one-time informational intervention, delivered through a printed leaflet, improve oral health knowledge during pregnancy? What factors are related to differences in oral health knowledge among pregnant women? Participants are pregnant women receiving care at Hospital La Fe. They will: Complete a questionnaire about their oral health knowledge. Receive a printed informational leaflet about oral health during pregnancy. Complete the same questionnaire again after a period of time to see if their knowledge has changed. Researchers will compare answers before and after the leaflet is provided to see whether oral health knowledge improves. They will also explore which personal or social factors are linked to different levels of oral health knowledge.

Structural and Intermediary Social Determinants of Oral Health Among Egyptian Women

Globally, there is substantial evidence indicating that low household income, lack of education, poor living conditions and inadequate psycho-social social support are potential risk factors for morbidity and premature death. Despite that, worldwide, there is scarcity in evidence on potential social determinants of oral health among different population groups.The study aims To identify the potential social determinants with an influence on oral health status of Egyptian women.

Oral Indicators for ED Screening

The main objective of this research project is to explore the capability of a standardized, evidence-based study tool (the OHEDs Checklist) in the early identification of oro-dental manifestations potentially indicative of an eating disorder. The secondary objective is to evaluate the sensitivity and specificity of the OHEDs Checklist in comparison with validated screening instruments for eating disorders, namely the ESP, SCOFF and DEQ questionnaires.

The Use of Functional Confections in Promoting Oral Health

In areas of the world where populations are undernourished poor oral health is prevalent. Diets rich in fruit and vegetables are thought to have many health benefits including reducing the risk of oral cancer or gum disease. In particular fruits such as strawberries contain many different compounds which may be responsible for these proposed health benefits. From this study, the researchers hope to gain information about how the tissues in the mouth absorb strawberry gummies in a population of habitually smoking and never smoking men and women. The researchers will measure inflammation hormones in your saliva and urine and the genes in your mouth and blood. Two different strawberry gummies will be tested in this study. The strawberry gummies were developed at OSU in the Department of Food Science and Technology. One type of strawberry gummy will contain freeze-dried whole strawberries while the other type will have no fruit. In total the eight pieces of strawberry gummies that you will consume in one day will be at most equal to 1 cup of whole strawberries. The research team believes the two strawberry gummies may be digested and absorbed differently and that components in the strawberry gummies may be helpful for oral health.

Evaluating the Impact of Various Dietary Nitrate Supplements on Oral Health

This study aims to investigate the effects of different dietary nitrate supplements, versus placebo, on microbiological and immunological markers associated with oral health in people aged 18-65 years. The main research questions are: * How do different dietary nitrate supplements (beetroot crystals vs. beetroot juice) affect oral health markers, including salivary pH and oral microbiome composition? * What is the acceptability and ease of integrating one of dietary nitrate supplements, made from beetroot but processed as freeze dried crystals or juice, into the daily diet? To answer these questions, the study will compare results from three groups of participants, who will be randomly assigned to one of the following study arms: Group 1: The control group will consume a placebo beetroot supplement completely free of nitrate in juice form. Group 2: The beetroot juice group will consume a beetroot supplement standardised to contain \~ 400 mg of nitrate in juice form. Group 3: The beetroot crystals group will consume a beetroot supplement standardised to contain \~400 mg of nitrate in freeze dried crystal form. The study will follow a randomised, single-blind, placebo-controlled, parallel design, and the intervention will last for four weeks. Data will be collected by providing pre- and post-intervention saliva samples tongue swabs, and various questionnaires will be completed at baseline and at the end of the study. In addition, at the end of the second week of the intervention period, participants will be asked to collect a saliva sample over three consecutive days at home.

A Study on the Correlation Between Oral Health and Delirium in Surgical Inpatients

Delirium is a clinical syndrome characterized by acute attention deficits, altered consciousness, and fluctuating cognitive dysfunction, typically triggered by multifactorial causes such as physical illness, medication use, or postoperative stress . As the most common complication in hospitalized patients, delirium is highly prevalent among elderly surgical populations, with postoperative delirium (POD) occurring in 7.5%-27.5% of cases, and rates rising to 50%-70% in intensive care unit (ICU) patients . Its onset is closely associated with poor prognoses, including long-term postoperative cognitive decline , increased mortality, prolonged hospitalization, and elevated healthcare costs (annual costs in the United States ranging from 38billionto152 billion) . Early prevention and screening of POD are therefore critical to improving patient outcomes and reducing healthcare burdens. Surgical patients' oral health issues exhibit multifactorial pathogenesis: intrinsic factors (e.g., age-related tooth loss, malnutrition-induced mucosal repair impairment, and chewing dysfunction due to reduced skeletal muscle mass) and iatrogenic factors (e.g., endotracheal intubation trauma, salivary secretion suppression from analgesics, and inadequate perioperative oral care). Poor oral health in hospitalized patients is often attributable to aging, physical dependence, cognitive decline, malnutrition, low skeletal muscle mass/strength, and comorbidities. The recently proposed concept of "Oral Frailty"-a progressive decline in oral structure and function-strongly predicts physical frailty, dysphagia, malnutrition, long-term care needs, and mortality in community-dwelling older adults The impact of oral health on cognitive function may involve three pathways : Mechanical pathway: Tooth loss disrupts masticatory motor function, reduces cerebral blood flow, and diminishes afferent stimulation from peripheral receptors (e.g., periodontal ligaments), leading to weakened neural connectivity and regional brain atrophy. Neurodegenerative pathway: Tooth loss accelerates neuronal damage via apoptosis and mitophagy, increasing amyloid-beta deposition in the brain. Inflammatory/metabolic pathway: Systemic inflammation, metabolic dysregulation, microbial-gut-brain axis interactions, and activation of microglia/astrocytes drive neuroinflammatory cascades in the central nervous system. Given these connections, oral frailty may act as an independent risk factor distinct from general frailty and a potential contributor to POD. These findings suggest that oral frailty could serve as a unique biomarker for perioperative neurocognitive disorders, mediating their pathogenesis. Systematic investigation into the spatiotemporal relationship and mechanisms linking oral health to POD in surgical patients holds significant clinical value for developing multimodal prevention strategies.

PROSENIOR. Prevention of Pressure Ulcers, Malnutrition, Poor Oral Health and Falls Among Older Persons Receiving Municipal Health Care and Are Registered in the Quality Registry Senior Alert

Effect of Hypochlorous Acid-containing Mouthwash on Healing After Impacted Wisdom Tooth Surgery

INTRODUCTION: Local chemotherapeutic agents are used to reduce inflammation after impacted tooth extraction and to minimize possible complications, as well as to increase patient comfort. The aim of this study is to compare the clinical and microbiological effects of different mouthwashes/mouth rinses/antiseptic agents applied after impacted surgical tooth extraction in patients with impacted mandibular third molars within the scope of pain, wound healing and total bacterial load criteria; postoperative complications and healing process. MATERIAL AND METHODS: According to the Pell and Gregory classification, 96 volunteer patients with unilateral or bilateral Class 2 position A and B impacted mandibular third molars, being systemically healthy (ASA class 1), being between the ages of 18-45/young adult will participate in the study. The patients will be divided into 3 groups: Group 1, Patients who will be administered hypochlorous acid-containing mouthwash in addition to standard treatment after mandibular third molar surgery; Group 2, Patients who will be administered chlorhexidine gluconate-containing mouthwash in addition to standard treatment after mandibular third molar surgery; Group 3, Patients who will be administered sterile saline-containing mouthwash in addition to standard treatment after mandibular third molar surgery. Demographic data before the surgical procedure will be recorded in the patient follow-up form (Appendix-1). As a standard postoperative approach, all patients will be prescribed antibiotics (875 mg Amoxicillin+125 mg clavulonic acid, Augmentin-BID film-coated tablets, GlaxoSmithKline, Istanbul, Turkey), analgesics for use after surgery, and mouthwashes will be given depending on the groups. Patients will be asked to take antibiotics in the morning and evening for 5 days, use mouthwash for 7 days starting from the day after the procedure, and use mouthwash only when deemed necessary, and will be asked to record the amount they use on the home assessment form (ANNEX-2). All patients will be evaluated on the 7th day after the operation, and suture samples will be taken for microbiological load determination. All evaluations will be made before the operation and on the 7th day after the operation; and will be recorded on the patient assessment form (ANNEX-1). First of all, demographic information including age, gender, education level and the operation area will be recorded for all patients. Two separate forms with VAS scales for pain will be given to patients to mark every day for 7 days after the extraction. The patient will be asked to mark the level of pain they feel on the scale. The amount of analgesic use in the home assessment form will also be recorded within the scope of the pain assessment. Healing in the wound area will also be evaluated on the 7th day.

Sport Mouthguards: Devices for Preventing Dental Injuries in Sports

Objective: To evaluate the impact of mouthguards (MG) on acceptability, incidence of soft tissue injuries, periodontal and salivary parameters, as well as on the perception of the body in sports practice (PeCoPes) and on the quality of life of athletes, and evaluate the consequences of use on the characteristics, state of conservation, and biological and physical properties of the MG itself. Methodology: This is a longitudinal study that will include children, adolescents, and adults aged 7 to 30 years who practice sports and require MGs. Sociodemographic data, medical history, dental history, dietary habits, and sports practice data will be collected. Participants will undergo a complete oral clinical examination. Data on knowledge of traumatic dental injuries (TDI) and MGs will also be collected. Before the MG is delivered, immediately after installation, and at 1, 3, and 6 months after use, the following parameters will be evaluated: presence of mucosal injuries, visible plaque index, gingival bleeding index, salivary flow, salivary pH, buffering capacity, and salivary microorganism count. Acceptability will be evaluated before the MG is delivered, immediately after delivery, and at 1, 3, and 6 months after use. PeCoPes and quality of life will be assessed before, 1, 3, and 6 months after MG use. The MG will be evaluated for bacterial contamination, delamination, roughness, dimensional changes related to shape and thickness, color change, and conservation status. The data will be tabulated and analyzed using SPSS 21.0, and appropriate statistical tests (p\<0.05) will be performed according to the study objectives.

Involving Parents to Improve Tooth Brushing for Autistic Children.

Parents of autistic children have reported a lack of understanding by oral health care staff around delivery of oral health preventive habits for their children. This study aims to investigate if oral healthcare training utilising the Mini Mouth Care Matters (MCM) programme designed for Special Education Settings (SES) enhances parent confidence in their ability to influence their child's oral health, increases toothbrushing episodes and reduces challenging toothbrushing behaviour of autistic children. The participants of this study will be parents of children who have a confirmed professional diagnosis of Autistic Spectrum Disorder. Parents will be recruited via healthcare professionals who provide oral health promotion within SES. Special Education Settings will be randomised into one of two groups. Group one will receive 'delivering better oral health' advice. Group two will receive the MCM user intervention guide for oral healthcare. A maximum of 30 parents will be recruited into each intervention arm. A maximum of 60 parents will be recruited to the study.

Determining the Viability a Lozenge Dosage for Probiotics

Gingivitis is an oral disease condition affecting 50% to 90% of adults globally. Gingivitis is a reversible inflammatory condition caused by the accumulation of dental plaque and the associated disruption of the host-microbial homeostasis. During gingivitis, the microbial community shifts from gram-positive health-associated bacteria, to gram-negative disease associated species. This shift triggers inflammatory responses, leading to tissue damage and, in some cases, progression to periodontitis. A promise area of oral health is treating the oral cavity with gram-positive probiotics to improve oral health. One promising candidate is S. salivarius SALI-10. Typically oral probiotics are dosed to the oral cavity using lozenges. This study is a pre-clinical Phase 0 trial to determine is a lozenge is a viable dosage form for the delivery of salivarius SALI-10 oral probiotics.

Improved Oral Health and Dental Care in Children with Congenital Heart Disease

Background: Congenital heart disease (CHD) is one of the most common congenital anomalies in children. As the risk for endocarditis following bacteraemia is more common during daily oral hygiene routines, such as tooth brushing, than during dental treatment, the maintenance of optimal oral health in children with CHD may be considered of outmost importance. Children with CHD have a higher caries prevalence compared to healthy controls. Aim: The primary aim of the study is to explore if an educational intervention including information, counselling and support provided at early stage to families affected by major CHD, or CHD combined with a syndrome, can increase the awareness of the importance of maintaining of good oral health, and avoid the development of poor oral health including dental caries, leading to less dental anxiety and a higher oral heath related quality of life. The secondary aim is to elucidate factors associated with the development of poor oral health and/or orofacial dysfunction as well as family attitudes and needs of support. Hypothesis: Early information, counselling and support will lead to a) increased awareness of the importance to maintaining good oral health, b) prevent the development of poor oral health and dental caries, c) lead to less dental fear, and d) lead to higher oral heath related quality of life. Study design: Randomized educational intervention trial. Study population: Children born in Finland and under 12 months of age in 1.7.2017-31.12.2021 with, a) major CHD and potentially included in the criteria of endocarditis prophylaxis, or b) with a major CHD combined with a chromosomal syndrome, will be offered to participate in the study. Patients will be recruited until 200 patients are obtained at the Helsinki University Children's Hospital. A control group consisting of approximately 100 healthy children will also be recruited at birth. Main outcomes: Dental caries, dental anxiety, oral health related quality of life, and awareness of importance to maintain and behaviour to maintain good oral health. Significance: Better information to patients leads to better possibility to achieve good oral health. Better oral health leads to 1) less dental procedures and thereby less dental anxiety, 2) less dental procedures under general anaesthesia, which may potentially be a risk procedure for the child with CHD, and 3) better oral health related quality of life.
