Large Language Models for Dental Radiology Report Generation From Structured Textual Data

The purpose of this observational methodological study is to evaluate whether large language models can transform structured dental radiology data into clear narrative radiology reports. Large language models are computer programs that can generate text from information provided to them. In this study, the input will consist of organized dental radiology findings, such as chart-style or diagram-based information about teeth and surrounding structures. Dental radiology reports are used by dentists and other health care providers to understand imaging findings and support clinical documentation. Preparing narrative reports may be time-consuming, and the wording of reports may vary between clinicians. This study will examine whether language-model-assisted report generation can produce reports that are complete, accurate, understandable, and clinically useful. The study will compare reports generated with support from large language models with traditionally prepared reports. Researchers will also assess how the wording of the prompt and selected model parameters influence report quality. In addition, the study will analyze errors and safety risks in generated reports and evaluate whether such a system could be practical in a dental radiology workflow. The language model will not make treatment decisions, and generated reports will be used for research evaluation only.

Comparison of Patient-Reported Comfort Between Two Clear Aligner Trimming-Line Designs: A Split-Mouth Study

* The trimming-line design of clear aligners (supragingival versus juxtagingival) is a routine clinical decision whose influence on patient-reported comfort has not been established; available evidence on aligner comfort derives almost exclusively from comparisons with fixed appliances. * This observational, cross-sectional study compares two clear aligner trimming-line designs with respect to patient-reported comfort: a supragingival design, whose edge rests on the marginal gingiva, and a juxtagingival design, whose edge follows the gingival contour without covering it. Because the two designs sit differently against the gingival soft tissue, they may be experienced differently during wear. * Participants are patients already wearing one trimming-line design on one dental arch and the other on the contralateral arch; each participant thus serves as their own control. After a minimum of four weeks of wear, participants complete a 20-item questionnaire once, rating the frequency of defined oral experiences for the maxillary and mandibular arch separately on a three-point ordinal scale (0 = none, 1 = occasional, 2 = frequent). * The questionnaire is anonymous; the design worn on each arch is identified from which of two identical forms a participant completes. Responses for the two designs are compared within each participant. The study evaluates whether trimming-line design is associated with differences in patient-reported comfort.

Oral Health Education for Pregnant Women

The goal of this research is to investigate oral health knowledge in pregnant women receiving care at Hospital La Fe and to see whether a one-time informational intervention improves this 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.

Dysbiosis of Methanogenic Archaea and Nanoarchaea in the Oral Microbiome

Need to improve understanding of oral dysbiosis in the elderly and/or immunocompromised individuals (involvement of nanogenes in these dysbiosis) Comparison of dysbiosis identification between results from dental plaque samples and saliva samples (the saliva sample is non-operator-dependent due to its ease of collection). Comparison of the reliability of results obtained with this type of saliva sample versus results obtained with dental plaque samples, which are considered the reference sample type (Antézack 2023). Primary objective To estimate the prevalence of dysbiosis in individuals with oral frailty versus individuals without oral frailty. In this project: * Dysbiosis will be defined by the presence of Archaea (Bringuier 2013). For the primary objective, prevalence will be estimated based on dental plaque samples. * The population with oral frailty will be defined as individuals over 60 years of age or those with immunosuppression. Hypothesis: The expected proportion of dysbiosis in the population with oral health vulnerability is 40%, whereas the expected proportion of dysbiosis in the population without oral health vulnerability is 20% (Li CL 2009). Secondary objectives Estimate the prevalence of dysbiosis in the two populations based on a saliva sample \- Compare the results from the sample

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.

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.

Caries-Obesity Prevention in Children by Modifying Risk Behaviors Among Parents With Immigrant Background-COP Study

Immigrants constitute 18.2 % of the whole population in Norway. Health inequalities were previously reported, and immigrant status has been associated with a high risk of caries and obesity in children. Lack of parental knowledge, poor communication, ethnic and cultural differences are suggested to be reasons for the observed discrepancies. Therefore, research-based knowledge about the social, psycho-social and cognitive factors, that direct health / dental health-related behavior in families with an immigrant background is needed. Aims The main goal of this project is to assess attitudes and behaviors related to health/oral health among immigrant parents with newborn children (0-6 months). Develop an intervention programs with the aim of increasing the parent's knowledge of the children's oral hygiene/food habits and to evaluate in a follow-up study the effect of intervention on parents' knowledge and attitude with regard to dental caries and obesity. Methods Parents with immigrant status will be recruited from primary health centers located in the western part of Norway when meeting for children's vaccination. Primary health care centers will be conveniently divided into an intervention and control group. Intervention in form of a health/dental health information translated into different native language will be provided for the intervention group. The control group will receive regular primary care health information. Efficacy of the intervention will be assessed as differences in change scores between intervention and control group regarding parental attitudes, knowledge and behaviors and children's quality of life related to health and oral health, children's body mass index and early childhood caries. Objective of this work are consistent with community needs to eliminate health/social inequalities and it is anticipated that a culturally adapted interventions can be implemented among immigrant families at a moderate cost.
