NEW YORK (Reuters Health) , May 21 In a small case-control study, chronic periodontitis was associated with an elevated risk of tongue cancer, independent of smoking status and other potential risk factors. “We expected to see an association, given the results of earlier studies linking chronic infections and inflammation to cancer risk in other organs,” lead author Dr. Mine Terzal, from the University at Buffalo School of Dental Medicine in
NEW YORK (Reuters Health) Feb 19 For the first time, teeth grown in culture from single cells have been used successfully to replace natural teeth in mice, Japanese researchers report in the February 18th online issue of Nature Methods. Dr. Takashi Tsuji, from the Tokyo University of Science in Chiba, and colleagues developed a three-dimensional organ-germ culture method to regrow ectodermal organs, such as teeth and hair follicles. The researchers
Extended reality (XR) technology may help reduce dental anxiety in adults by lowering one’s blood pressure, heart rate, and pain during treatments, according to a study recently published in the Journal of Dentistry. Furthermore, virtual reality (VR) technology may complement traditional anxiety management methods, with tailored interventions potentially improving effectiveness, the authors wrote. “Our findings suggest that XR technology effectively alleviates dental anxiety in adults,” wrote the authors, led by
Epinephrine is an essential tool in dental care, playing a critical role in pain management and procedural control. Most commonly, we use it to enhance the duration of local anesthesia, decrease systemic absorption, and minimize bleeding by vasoconstriction. This allows for more extended and controlled procedures with fewer complications. Pharmacologically, epinephrine works by stimulating various adrenergic receptors. This results in vasoconstriction, increased heart rate, and relaxed airways. In dentistry, vasoconstriction
Do two-appointment dentures sound too good to be true? Most dentists have grown accustomed to the challenging and time-consuming conventional denture workflows. Molds, try-ins, fittings, and adjustments can lead to many appointments and a lot of chairtime for your patient. In this webinar from Dandy, Dr. Robert Lee from Omalee Dental shares his experience adopting a digital denture workflow, including: ul.editorialList li {margin-bottom:6px;} How he transitioned his team What his
From a throbbing tooth or aching jaw to a pounding migraine, orofacial pain afflicts 5% to 12% of the population. Such pain can hinder daily activities like eating, toothbrushing, and mask wearing, yet opioid-based pain relievers carry the risk of misuse. Understanding how facial nerves process pain signals could help scientists find safer and more effective pain interventions. U.S. National Institute of Dental and Craniofacial Researchers (NIDCR) researchers recently caught
Microchips that mimic parts of the human body may sound futuristic, but these devices — called organs-on-chips — are already being used to study human biology. Made from plastic, with grooves that are lined with cells and channels that transport air and fluids, these chips can simulate aspects of organ structure and function. Chips have been designed to mimic many different parts of the body, including beating heart tissue, air-filtering
Enamel, the pearly white tissue that coats and protects our teeth, is the hardest tissue in the human body. It’s formed with the help of proteins called amelogenins. But as a recent study shows, these proteins appear to do more than fortify our teeth — they may also help keep our bones strong. A research team led by U.S. National Institute of Dental and Craniofacial Research (NIDCR) senior investigator Ashok
With vinyl chairs, disinfectant-scented air, unfamiliar lights, and high-pitched tools, a dental office can be a stressful place for any patient. But the sounds and sensations can be outright overwhelming for children with autism spectrum disorder (ASD). Dominique Como, an occupational therapist supported by the U.S. National Institute of Dental and Craniofacial Research (NIDCR), is working to make the dental office more suited to the needs of children with ASD.
As a registered dental hygienist, I am concerned for our communities, fellow healthcare professionals, and our world during this time. COVID-19 has presented us with an asymptomatic, airborne-spread, respiratory disease resulting in death or long-term health effects for many. It has opened the eyes of many (but not all) dental professionals as to where our facilities are lacking in environmental safety. According to the U.S. Department of Labor, dental hygiene
U.S. citizens headed to the polls on November 6 to weigh in on a number of dental-related issues in the midterm election. Local and state ballot measures ranged from community water fluoridation to the future of soda taxes, and five dentists were elected to the U.S. House of Representatives. Voters in multiple states decided to forgo increasing taxes on cigarettes to fund education and healthcare initiatives, while the results were
