Researchers at the University of Saskatchewan are leading a study to help dentists recognize signs of domestic violence and learn how to respond. “At the end of the process, we want to create something that is approachable and will be disseminated on socials and online platforms,” Dr. Liran Levin, a periodontist and researcher at the … Read more
UB team traces saliva’s evolution back to primates, linking diet to salivary proteins and opening doors to personalized oral-health diagnostics.
Adults with type 2 diabetes who clean between their teeth at least three times a week may have more stable 24-hour blood glucose levels, new research shows. A clinical study, published in advance in the American Diabetes Association’s journal Diabetes Spectrum, found that adults who flossed or used interdental brushes three or more times weekly … Read more
The gel acts as a scaffold, drawing calcium and phosphate ions from saliva to rebuild the enamel through a process called epitaxial mineralization.
Canadians missing five or more natural teeth face roughly a 76 per cent higher risk of being hospitalized for any cause and a 120 per cent higher risk of being hospitalized for circulatory-system diseases, according to a new Statistics Canada cohort study. In line with previous global research on the mouth-body connection, the study suggests … Read more
A new U.S. study of death records from 1979 through 2018 found that both male and female dentists had higher suicide mortality than the general population, and that the risk has trended upward since the mid-1990s. The study, published online ahead of print in the Journal of the American Dental Association in October 2025, set … Read more
A new study published by the American Academy of Neurology suggests that having both gum disease and cavities may nearly double a person’s risk of ischemic stroke compared with having a healthy mouth. The study found that participants who had both conditions were 86 per cent more likely to experience a stroke compared to those … Read more
A naturally occurring compound found in fruits such as apples, guava and figs could help prevent and treat gum disease, according to new research from São Paulo State University (UNESP). Scientists at the university’s Araraquara School of Dentistry (FOAr-UNESP) and the Faculty of Pharmaceutical Sciences (FCFAr-UNESP) identified morin, a plant-derived flavonoid concentrated in fruit peels … Read more
A systematic review published by researchers affiliated with the American Dental Association (ADA) in October 2025 found that cannabidiol (CBD) — the non-psychoactive component of cannabis — shows promise as a “safe adjunct” for managing oral pain and inflammation. The paper, titled “Therapeutic potential of cannabidiol in oral disorders: A systematic review of clinical evidence,” … Read more
Nurse Rod Salaysay works with all kinds of instruments in the hospital: a thermometer, a stethoscope and sometimes his guitar and ukulele. In the recovery unit of UC San Diego Health, Salaysay helps patients manage pain after surgery. Along with medications, he offers tunes on request and sometimes sings. His repertoire ranges from folk songs in English and Spanish … Read more
A new study published Oct. 10 in BMC Geriatrics has found that the faster older adults lose their teeth, the greater their risk of dying — regardless of how many teeth they had at the start. Previous research has typically looked at tooth count at a single point in time. This study, led by researchers … Read more
Predicting when dental growth spurts occur has long challenged clinicians, as treatment before or after a growth peak can be less effective. Now, researchers in South Korea have developed an artificial intelligence (AI) system that can forecast those peaks using a simple neck X-ray. Researchers from Korea University Anam Hospital, KAIST and the University of … Read more
A new study from King’s College London suggests artificial intelligence (AI)-powered speech recognition could ease administrative burdens for dental professionals, though accuracy concerns remain. Published in the Journal of Dental Research, the study evaluated 10 automatic speech recognition (ASR) tools and found that the most advanced systems were both faster and more accurate than manual … Read more
A new study published in the National Library of Medicine in late September finds that “dental shame” can deter people, especially older adults from seeking oral-health treatment. The research was conducted by Louise Folker, Esben Boeskov Øzhayat and Astrid Pernille Jespersen of the University of Copenhagen; Luna Dolezal of the University of Exeter; community volunteer … Read more
Fewer than half of U.S. dentists screen adolescents for substance use, according to what authors describe as the first national survey of dentists’ practices on the issue, published online ahead of print in the Journal of Adolescent Health. The Substance Use Disorders (SUDs) Screening Survey assessed dentists’ knowledge, attitudes and current practice behaviours related to … Read more

Yet another study is strengthening the connection between oral and overall health — this time suggesting that heart attacks may partly be an infectious disease. Researchers from Finland and the UK, writing in the Journal of the American Heart Association (JAHA), report they found bacterial DNA from common oral species inside arterial plaques. Their findings, … Read more
Oral health is increasingly linked not only to overall health, but also to confidence and daily behaviours like smiling. A new survey released Friday found that more than half of Canadians say they would smile more if their teeth were healthier or better looking. The poll, conducted in August by Leger Marketing for 123Dentist, surveyed … Read more
New York University scientists are developing a zinc-based treatment for cavities that could eliminate the need for drilling and filling, while also avoiding the black staining that limits use of existing products. Marc Walters, a professor of chemistry at NYU, has created a colourless compound called zinc tetramine difluoride, which forms zinc oxide crystals deep … Read more
A bacterium best known for causing tooth decay has been linked to Parkinson’s disease, in what researchers call the first study to show a direct microbial pathway driving the condition. The study, published this month in Nature Communications, was led by researchers in South Korea at POSTECH and Sungkyunkwan University, with collaborators from Seoul National … Read more
