Systematic Review Open access Published: 08 June 2025
Association of tooth brushing behavior with risks of major chronic health outcomes: a scoping review
Oral hygiene behavior has been increasingly recognized as a potential contributor to chronic disease prevention. This scoping review aimed to synthesize existing evidence on the associations between tooth brushing behavior (as a proxy for oral hygiene) and major chronic health outcomes, including cardiovascular events (e.g., myocardial infarction, atrial fibrillation, heart failure), stroke (ischemic, hemorrhagic, and subarachnoid), hypertension (HTN), metabolic syndrome (MetS), and chronic kidney disease (CKD).

Assessment of Oral Health Literacy and Influencing Factors: Retrospective Analysis of Patients Treated by Dental Students ORIGINAL ARTICLE Open Access
To prevent and manage oral health problems, patients must have an optimal level of oral health literacy. Patients gain this knowledge by communicating with dentists and other oral health professionals.
To assess oral health literacy among patients undergoing treatment, a retrospective analysis was completed by evaluating the Oral Health Literacy Profile (OHLP), which assesses oral health behavior and knowledge, of adult patients treated by fourth- and fifth-year dental students. Statistical analyses and linear regression modelling were then conducted, according to the study.

Linking periodontitis and Alzheimer’s disease: systemic inflammation as a shared mechanism
Periodontitis is a multifactorial disease that leads to the progressive destruction of the tooth’s supporting apparatus in the presence of bacterial plaque, the primary etiological agent; as responsible for systemic inflammation, it can activate the host’s immune response. Alzheimer’s disease (AD) is a persistent neurodegenerative disorder characterized by a progressive cognitive decline in which inflammation plays a significant pathogenic role. This narrative review examines the most recent scientific evidence on the already established association between periodontal disease and Alzheimer’s disease.

A Systematic Review and Meta-Analysis Association Between Periodontitis and Age-Related Macular Degeneration: Potential for Personalized Approach
A new systematic review and meta-analysis found a significant association between periodontitis and age-related macular degeneration (AMD), suggesting periodontal disease may be an underrecognized modifiable risk factor for the most common cause of irreversible vision loss among the elderly.
Periodontitis is associated with AMD. Unlike other important but unmodifiable risk factors such as genetic predisposition and high age, periodontitis is a risk factor that can be treated and potentially eliminated, thus allowing for a personalized approach for risk elimination in AMD. Attention should be given to the dental health of patients at risk of AMD. However, more studies are warranted to understand the impact of eliminating periodontitis in patients with periodontitis and how that modulates the risk of AMD.
The study builds on prior meta-analyses and provides an updated synthesis of the evidence. The findings reinforce the need for prospective, well-controlled studies that can clarify the relationship and assess the impact of periodontal treatment on AMD risk.

Debulking influenza and herpes simplex virus strains by a wide-spectrum anti-viral protein formulated in clinical grade chewing gum
A novel clinical-grade chewing gum could help reduce viral loads of influenza and herpes simplex virus strains. In a laboratory-based study published in Molecular Therapy, researchers examined the efficacy of a novel clinical-grade chewing gum formulated with FRIL — a natural viral tap protein — in neutralizing several flu and herpes simplex virus strains.
The chewing gum left no aerobic bacteria, yeasts or molds after the bioburden test. The gum also was capable of trapping both HSV-1 and HSV-2 strains. Through a mastication simulation for 15 minutes, the chewing gum released greater than 50% of the FRIL protein. The researchers determined that a 2,000-milligram chewing gum tablet could be safe and effective at neutralizing the H1N1 and H3N2 flu strains and HSV-1 and HSV-2 strains.

The need for effective interprofessional collaboration between nutrition and dentistry
There are bidirectional relationships between diet and nutrition, systemic health and oral health. Diet and nutrition are fundamental to the prevention and management of chronic diseases. Systemic health can impact oral health. And oral health can influence diet and nutrition.
Dental hygiene and dental schools should consider having nutrition-oral health related topics taught by nutrition professionals. The accreditation board would make nutrition a fundamental part of dental curricula with a set number of hours and topics to be covered. This would not only provide dental trainees evidence-based education and up-to-date recommendations, but it would also foster interdisciplinary education and care.

A distributed coding logic for thermosensation and inflammatory pain
NIH study reveals how inflammation makes touch painful
Researchers uncover the cellular and molecular basis for sensing heat and inflammatory pain.
Researchers at the National Institutes of Health (NIH) have discovered clues as to how our bodies turn sensations such as heat and touch into signals sent to the brain — and how these signals can be altered by inflammation to drive pain. The research focuses on the nerve cells in the skin that help us detect the location, intensity, and emotional quality of touch, known as somatosensory neurons. By combining advanced imaging techniques with detailed molecular analysis, the researchers explored how heat and touch activate different types of receptor cells in mice.
Inflammation is well known to be linked to pain, but the understanding of what is happening on the cellular and molecular levels is less clear. In their experiments, researchers injected prostaglandin E2 into the skin, a molecule that causes inflammation and drives pain. With the inflammatory response set into motion, researchers found that certain neurons used for signaling pain (nociceptors) became active and sensitized to heat for a long duration, demonstrating the cellular processes at play.

Dasatinib and Quercetin Limit Gingival Senescence, Inflammation, and Bone Loss
Researchers at Penn Dental Medicine have developed a plant-based drug to help treat periodontal diseases, commonly known as gingivitis and periodontitis.
The anti-senescence therapy, or “senotherapy,” consists of an enzyme inhibitor called dasatinib and a natural flavonoid plant compound called quercetin, the university said in a statement on April 11.
“Our findings suggest that senotherapy offers a promising approach to preserving periodontal health,” said Dr. Esra Sahingur of Penn Dental Medicine. “Periodontitis is more than a bacterial infection—it’s driven by immune and metabolic dysfunction, cellular aging and inflammation. By targeting inflammation and senescent cells, we may disrupt the chronic disease cycle and unlock new preventive and therapeutic possibilities for oral and systemic health.”

High Sugar-Sweetened Beverage Intake and Oral Cavity Cancer in Smoking and Nonsmoking Women
This cohort study of 124 OCC cases from 162 602 women who participated in the Nurses’ Health Study found an OCC risk 4.87 times higher in participants consuming 1 or more SSB daily compared with less than 1 SSB monthly, increasing the rate of OCC by 3 people per 100 000 population over time. Similarly, the risk of OCC in nonsmoking or light-smoking and nondrinking or light-drinking participants was 5.46 times higher in those consuming 1 or more SSB daily compared with less than 1 SSB monthly, raising the rate of OCC to 3 more people per 100 000 population.
Women consuming at least one sugar-sweetened beverage (SSB) a day have an almost five times higher risk for oral cavity cancer (OCC) than those consuming less than one of these beverages a month. Risk increases to 5.46 times higher in nonsmoking/light-smoking and nondrinking/light-drinking women.

Burnout, Stress, and Wellbeing: The Rising Mental Health Crisis in UK Dentistry in Dental Care Professionals. A Quantitative Perspective
To determine if dental care professionals working in National Health Service (NHS) practices are more at risk of stress, wellbeing concerns and burnout than their private practice counterparts.
Principle findings
○
There was no statistically significant difference between private and mixed practice dental professionals on the combined scales. Dental hygienists, dental therapists and dental nurses working in mixed NHS dentistry are not more susceptible to stress, wellbeing issues and anxiety than their private counterparts according to the data set. More research is required to look at the potential occupational cocncerns for dental personnel.

The Impact of Female Hormones on the Periodontium—A Narrative Review
This is NOT open access, but interesting nonetheless.
To provide an updated narrative review of current concepts relative to the impact of female hormones on the periodontium throughout the life stages of the female patient. To analyse the implications for the clinician and to amalgamate the main findings from a wide range of empirical studies and theoretical perspectives.
Key findings demonstrate that hormone fluctuations have a direct and indirect impact on the periodontium, altering the bacterial flora of plaque biofilm to a composition more conducive to the development of periodontal disease and modifying the tissue response to local factors, producing anatomic changes in the gingivae that compromise the periodontium and influencing the regulation of the inflammatory cascade. These factors increase the risk of periodontal disease and susceptibility to other oral conditions associated with female hormone fluctuations.

Influence of Implant Surfaces on Peri-Implant Diseases – A Systematic Review and Meta-Analysis
The aim of this systematic review and meta-analysis was to evaluate the current literature on the effect of implant surface characteristics on peri-implant marginal bone levels (MBL), soft tissue periodontal parameters, peri-implantitis, and implant failure rates.
Conclusion: Machined surface implants were favoured in terms of lesser peri-implant MBL, though the difference was not significant. The analysis also demonstrated limited favourable outcomes in terms of periodontal parameters for machined surfaces, with slightly significantly better outcomes in terms of probing pocket depths. However, rough surface implants tended to display a lower implant failure.

Poor Oral Hygiene: A Hidden Risk Factor for Helicobacter pylori Infection
Helicobacter pylori (H. pylori) initially enters the human body through the mouth. The correlation between oral health and H. pylori infection status remains a topic of debate in the scientific literature. To elucidate the relationships between H. pylori infection and oral hygiene status and habits, we performed a cross-sectional study among dyspeptic patients.
Conclusion: The results of our research indicate a relationship between oral health and oral H. pylori infection, suggesting that poor oral hygiene may be associated with an increased risk of oral H. pylori colonization.

The Effects of Electronic Cigarettes on Oral Microbiome and Metabolome in 3D Tissue-Engineered Models
Recent studies have shown that electronic cigarettes (ECs) use disrupts the oral microbiome composition and diversity, impairing the metabolic pathways of the mucosal cells. However, to date, no reports have evaluated the role of EC exposure in the context of oral metabolome. Hence, the aim of this study was to investigate the role of EC aerosol exposure in the dysregulation of the oral microbiome and metabolome profile using in vitro 3D organotypic models of human oral mucosa.
This study underscores the significant impact of EC use on oral health, highlighting alterations in the oral microbiome, bacterial composition, and metabolite profiles via a clinically relevant in vitro 3D organotypic model of human oral mucosa.

Early Childhood Exposures to Fluorides and Cognitive Neurodevelopment: A Population-Based Longitudinal Study
It is important to maintain confidence in the risk and benefit balance of major caries-preventive programs using fluoride. The ongoing debate about potential effects of early-life exposures to fluoride on cognitive neurodevelopment requires high-quality scientific evidence. This study aimed to investigate the potential effects of fluoride exposure on cognitive neurodevelopment assessed with the Wechsler Adult Intelligence Scale 4th edition (WAIS-IV) in an Australian population-based sample.
Conclusion: This population-based follow-up study has provided consistent scientific evidence that early-life exposure to fluoride was not negatively associated with cognitive neurodevelopment. The findings, in combination with the current body of knowledge, provide assurance that the currently practiced WF programs are both effective and safe for young children.
