The groundbreaking study is the first to analyze records from community dental practices, where most Americans receive dental care. “The findings of this study give deeper insight into the longevity of dental procedures because it provides real-world data on a wider range of patients, not just

It involves a small device containing 57 microneedles, which, when placed on the gums, cheek or other location of the

Views on the usefulness of teledentistry in clinical settings. The participant’s ranking of procedures where teledentistry could be useful in clinical practice is shown in Fig. 1. Most participants (68.4%) considered patient triaging an important use for teledentistry in clinical practice followed by consultation (65.4%), educational purposes (42.5%), referrals (32.0%), treatment planning (17.3%) and others (3.7%). Procedures noted within the ‘other’ category included emergency treatment (2.0%), follow-up care (1.3%), rapport building

Over the last century the JDR has been dedicated to the dissemination of new knowledge and information on all sciences relevant to dentistry and to the oral cavity and associated structures in health and disease. To celebrate, the JDR is featuring a yearlong, commemorative article and podcast series that highlights topics that have transformed dental, oral and craniofacial research over

by King’s College London A study led by a team of periodontists and psychologists at King’s College London including dentistry consultants at Guy’s Hospital has found that tele-dentistry may be a valid option for first stage triage or follow-up consultations, saving patients attending clinics in person. With the significant impact of COVID-19 on dentistry, including the substantial rise in the use of video consultations, the team set out to investigate dentists’

Slender faces are also associated with overbites and left-handedness. Credit: Philippe Hujoel Individuals with a slender lower face are about 25 percent more likely to be left-handed. This unexpected finding was identified in 13,536 individuals who participated in three national surveys conducted in the United States. This association may shed new light on the origins of left-handedness, as slender jaws have also been associated with susceptibility to tuberculosis, a disease that has

An expert panel of dentists developed the first-ever guideline on this topic after extensive review of approximately 300 published studies. The guideline, published in the July issue of The Journal of

The study, which was conducted by researchers at Karolinska Institutet, is published in Nature Communications. Teeth develop through a complex process in which soft tissue, including connective tissue, nerves and blood vessels, is bonded with three types of hard tissue into a functional body

by University of Minnesota Dental decay is a significant public health concern for children and adults. In fact, it is the most common childhood disease. In a new study published in Applied and Environmental Microbiology, an interdisciplinary team of University of Minnesota researchers found some bacteria that absorb and accumulate phosphate from saliva may play a role in tooth decay – which causes cavities. The study suggests dental plaque contributes to dental decay by

Pediatric dentists report seeing more decay and cavities, along with serious infections—some even requiring treatment in the operating room. “We know there have been a lot of parents who were hesitant about coming to a dental visit,” says Cheen Loo, professor and chair
