A newly developed biomaterial derived from natural and pharmaceutical components is showing promise as a potential treatment for periodontitis. What if a fruit best known for its massive size could help repair the damage caused by one of the world’s most common causes of tooth loss? Researchers in Brazil have developed an experimental biomaterial that [...]
Researchers have uncovered why a common and costly dental implant infection often resists antibiotics. Dental implants have helped tens of millions of people regain a full set of stable, functional teeth, something traditional dentures cannot provide. However, between 10% and 20% of implant recipients eventually develop peri-implantitis, a serious infection that damages the jawbone around [...]
Scientists just uncovered the cellular “blueprint” that could one day let us regrow real teeth. Researchers at Science Tokyo have uncovered two distinct stem cell lineages that play a central role in forming tooth roots and the surrounding alveolar bone. By studying genetically modified mice and tracking how individual cells develop over time, the team [...]
Researchers created a fast 3D-printing method for zirconia dental restorations by cutting debinding time to under 30 minutes, enabling same-day, high-strength, customized crowns. The crown jewel of dental restoration technology may be in sight. Researchers at the University of Texas at Dallas have developed a way to 3D print permanent zirconia dental restorations in a [...]
For years, treating gum disease has meant scraping away plaque, cutting out damaged tissue or turning to antibiotics that kill bacteria indiscriminately. While newer therapies can regenerate lost tissue, doctors still lack a precise way to stop the infection without harming the mouth's healthy microbiome. New research from the University of Florida College of Dentistry offers a breakthrough.
Older Americans with oropharyngeal and oral cancers face high medical costs but are missing out on needed dental care, according to a new study by Associate Professor Onur Baser and colleagues. The study, published in Cancer Epidemiology, Biomarkers & Prevention, examined insurance claims from 2013–2024 for more than 100 million commercially insured adults and 7 million Medicare beneficiaries to…
Researchers have developed a targeted approach to combat periodontitis without disrupting the natural balance of the oral microbiome. The innovation could reshape how gum disease is treated while preserving beneficial bacteria. The human mouth contains a remarkably complex community of more than 700 bacterial species, yet only a small fraction are responsible for periodontitis. These [...]
Nitrous oxide used for sedating patients during dental appointments has a significant environmental impact, with wide variation in use and wastage across the UK, according to a new study by UCL (University College London) researchers.
Everyone who's had regular dental care knows the heavy lead apron that's draped across your body before taking X-rays of your teeth.
Settling into a cushy reclining chair and closing your eyes while soft music plays is appealing, except perhaps at the dentist's office. According to a recent report in the Journal of the American Dental Association, 72% of American adults harbor some degree of fear about going to the dentist, and almost 27% say their fear is severe.
Teeth are composites of mineral and protein, with a bulk of bony dentin that is highly porous. This structure allows teeth to be both strong and sensitive. Besides calcium and phosphate, teeth contain trace elements such as zinc. Using complementary microscopy imaging techniques, a team from Charité Berlin, TU Berlin and HZB has quantified the distribution of natural zinc along and across teeth…
The federal agency that provides health care to Native Americans and Alaska Natives has announced it will phase out the use of dental fillings containing mercury.
Medical gas plasma can render adenoviruses harmless within a short period of time. This has been demonstrated by a recent laboratory study conducted by the Leibniz Institute for Plasma Science and Technology (INP). The key factor here is that the plasma primarily attacks the outer protein shell of the viruses. No significant changes were found in the genetic material of the viruses. The results,…
Malocclusions, or misaligned bites, refers to a condition in which the upper and lower teeth do not align properly when the mouth is closed. It can arise from a variety of factors, including tooth position and jaw relationships. Crooked teeth or a misaligned bite can cause a whole host of problems, including speech issues and/or difficulty eating or properly cleaning teeth. What many don't…
Next time you're considering consulting Dr. ChatGPT, perhaps think again. Despite now being able to ace most medical licensing exams, artificial intelligence chatbots do not give humans better health advice than they can find using more traditional methods, according to a study published on Monday.
