Solid line, with neither condition; dashed line, with DM only; dashed and dotted line, with edentulism only; dotted line, with both conditions. Shaded areas are 95% confidence intervals (CIs). Estimated rates of cognitive decline: older adults aged 65 to 74 y (panel 1): neither = −0.29 (95% CI, −0.33 to −0.25), DM only

DOI: 10.1371/journal.pone.0276103 In Brazil, tooth loss is 19% more frequent among Black women than White men. Among women, it is 26% more frequent for Blacks than Whites. Among Blacks, self-defined on the basis of skin color, it is 14% more frequent for women than men. Black women are affected most,

by Frontiers Brushing twice a day keeps the dentist away—but can we improve on the toothpaste we use to maintain clean teeth, preventing medical issues that spiral from poor dental health? Most toothpastes use fluoride, a powerful tool for oral hygiene. However, fluoride can pose health problems in some cases, especially for children who consume too much fluoride by swallowing most of their toothpaste: children normally use only a tiny dose

by SPIE When combined with air drying, shortwave-infrared can be used to detect active dental cavities. This is possible because active cavities are porous and hold more water, which affects the infrared measurements around the affected area as the tooth dries. Credit: Chang et al., doi 10.1117/1.JBO.28.9.094801. Dental caries, also called “cavities” or “tooth decay,” can be debilitating. Modern dentistry has tried-and-tested solutions for treating caries of many shapes and sizes

Graphical abstract. Credit: ACS Biomaterials Science & Engineering (2023). DOI: 10.1021/acsbiomaterials.2c01039 Over 30 years of dentistry, Sami Dogan has treated just about every kind of tooth ailment. Cavities are simple to fill. Dental implants have become routine. But there’s one problem, he said, that annoys even the most experienced dentists: hypersensitivity, the painful sensation sparked by contact with hot, cold or acidic food. “We see patients with hypersensitive teeth, but we can’t

If you have experienced a toothache, you know it’s no joke. That searing pain in your mouth can keep you from concentrating, getting adequate sleep and so much more. Plus, not treating the root cause of a toothache can lead to bigger problems down the road. According to StatPearls, it’s estimated that 13% of adults seek care for dental infections or toothache every four years. Here, experts will walk you through

by Trinity College Dublin Trinity College Dublin researchers collaborating with University College London have demonstrated for the first time the low environmental footprint of water fluoridation compared to other preventive measures for tooth decay. The study is published in the British Dental Journal. Water fluoridation is regarded as one of the most significant public health interventions of the twentieth century. But as the climate crisis worsens, the contribution of healthcare and the prevention of

Having both diabetes and tooth loss contributes to worse cognitive function and faster cognitive decline in older adults, according to a new study published in a special issue of the Journal of Dental Research focused on aging and oral health. Our findings underscore the importance of dental care and diabetes management for older adults in reducing the devastating personal and societal costs of Alzheimer’s disease and other related dementias.” Bei Wu, vice

In an online survey of 502 individuals (260 female), participants were ‘significantly less willing to undergo more invasive procedures, such as gum surgery and a root canal, and significantly more willing to undergo procedures such as tooth cleaning or whitening performed by a robot,’ Embry-Riddle Aeronautical University researchers said.
