  • Patients with periodontitis have significantly increased risk of stroke before age 50, study indicates

    Periodontitis, an inflammation of the structures supporting the teeth, significantly increases the risk of stroke in people under 50 years of age who do not have any known predisposing causes. A study indicates that the more the inflammation had progressed in the mouth, the more serious the stroke. In the focus were individuals who had a stroke between the ages of 20 and 50. The study found that periodontitis was significantly more common among stroke patients. Not only did periodontitis increase the risk of stroke, its severity affected that of the stroke too. According to the study, dental procedures carried...

    November 21, 2022 Share Email 592205.jpg Credit: U.S. Military One of the keys to bringing home unidentified military remains, including POW/MIAs and the more than 81,500 soldiers unaccounted for in conflicts dating back to World War II, is using science to determine where home might be. University of Utah scientists are engaged in an effort, in support of the Defense POW/MIA Accounting Agency, to develop methods that can trace the geographic origin of remains, particularly teeth. Why teeth? Because everyone’s body, including their teeth, contains a record of where they’ve lived and traveled in the form of various stable isotopes...

    I remember being a kid and seeing my grandmother without her dentures for the first time. It was a harrowing experience. Now my dad has dentures so, genetically speaking, I’m several decades out from needing some myself. However, it’s possible that modern medicine will solve the issue of lost teeth by then, thanks to a new drug that's about to enter human trials. The medicine quite literally regrows teeth and was developed by a team of Japanese researchers, as reported by New Atlas. The research has been led by Katsu Takahashi, head of dentistry and oral surgery at Kitano Hospital....

    The world's first human trial of a drug that can regenerate teeth will begin in a few months, less than a year on from news of its success in animals. This paves the way for the medicine to be commercially available as early as 2030. The trial, which will take place at Kyoto University Hospital from September to August 2025, will treat 30 males aged 30-64 who are missing at least one molar. The intravenous treatment will be tested for its efficacy on human dentition, after it successfully grew new teeth in ferret and mouse models with no significant side...

    Since the fourth millennium BCE, when urban civilizations first appeared in ancient Mesopotamia, humans have strived to achieve proper dental hygiene. Yet the nylon-bristled toothbrush we use today didn’t come along until the 1930s. For the thousands of years in between, people relied on rudimentary tools that evolved with scientific knowledge and technological advancements over time. Some of the earliest toothbrush predecessors date as far back as 3500 BCE. Here’s a look at how people kept their teeth clean before the modern toothbrush.AdvertisementChew Sticks and ToothpicksSometime around the year 3500 BCE, the ancient Babylonians (located near modern-day Iraq) created a...

    A new paper in Molecular Biology and Evolution, published by Oxford Univeristy Press, uncovers well-preserved microbiomes from two 4,000 year old teeth in a limestone cave in Ireland. These contained bacteria that cause gum disease, as well as the first high quality ancient genome from S. mutans, an oral bacterium that is one of the major causes of tooth decay.These discoveries allowed the researchers to assess the impact of past dietary changes on the oral microbiome across millennia, including major changes coinciding with the popularization of sugar and industrialization. The teeth, both derived from the same Bronze Age man, also...
  • Ancient Italian Skeletons Had Hemp In Their Teeth, Archaeologists Discover

    In a new analysis of thousands of teeth from ancient skeletons buried at a site near Naples, Italy, archaeologists have discovered that people were using their mouths to help with their work -- occupations that likely involved processing hemp into string and fabric. We all use our teeth as tools -- to open bottles, hold pieces of paper, or even smoke a pipe. When we do this, we open ourselves up to the possibility of cracking our teeth but also create microscopic grooves and injuries to the enamel surface. Since teeth don't remodel like bones do, these tiny insults remain...

    Teeth from long-dead people and animals are divulging the history of modern-day pathogens.Ancient DNA extracted from the teeth of humans who lived long ago is yielding new information about pathogens past and present. In one of the latest studies, researchers uncovered and sequenced ancient herpes genomes for the first time, from the teeth of long-dead Europeans. The strain of herpes virus that causes lip sores in people today — called HSV-1 — was once thought to have emerged in Africa more than 50,000 years ago. But the new data, published in Science Advances on 27 July1, indicate that its origin...

    A man with a metal detector searching a freshly plowed carrot field in Switzerland found a large ornate jewelry set dating to the Bronze Age — as well as other surprising items including a bear's tooth, a beaver's tooth and a fossilized shark's tooth, local officials said this week. Franz Zahn made the unusual discovery in August while he was "out and about in a freshly harvested carrot field" in Güttingen, about 50 miles northeast of Zurich, officials from Thurgau Canton said in a Monday news release. Zahn initially found a bronze disc, and immediately realized it was an "extraordinary...

    One of the things we probably all hated at one point as a kid was brushing our teeth. Standing in the bathroom while your parent supervises to make sure we are cleaned them properly, it's a hatred that you eventually grow out of when you realise it's important to keep your teeth clean. But for some people, it can become more of an on-going issue for multiple reasons - some of which can't be helped. One of these people was Jay, who went onto Channel 4's Embarrassing Bodies back in 2017 about his teeth, which he admitted he hadn't brushed...

    A new method of controlling inflammation and sugar levels for oral and systemic disease prevention using a common diabetes drug has been discovered by a team of researchers. A team of researchers have found new ways of stopping periodontal (gum) disease and potentially reducing the incidence of diabetes and obesity. This new approach focuses on controlling inflammation and sugar levels in both the mouth and body with a common type 2 diabetes drug, Metformin. The only treatment strategy currently available to tackle gum disease is to deep clean the teeth to rid the mouth of bacteria, as well as prescribing...

  • Are antidepressants affecting your teeth? How common prescription pills could make you dental implants fall out

    Could your prescription pills affect the outcome of dental implant surgery? It’s a problem highlighted by a recent study from dentists in Spain. They found that people who were taking antidepressants — specifically, selective serotonin reuptake inhibitors (SSRIs) — at the time of their surgery, and for at least one year beforehand, had a more than 4.5-fold increased risk of their implants failing. The 170 patients in the study were taking some of the most commonly prescribed SSRIs in the UK, such as citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine and sertraline. A ‘failed’ implant is defined as the implant falling out...

    Once again hunters can register their moose online and submit tooth as proof.Moose season is underway this week and hunters are out in big numbers this year.The province issued 5,107 licences for the hunt, which runs until Sept. 24.That's the highest number since 1995. Dwayne Sabine, a biologist with the Department of Natural Resources and Energy Development, said this year's increase was largely due to a drop in hunter success rates. "So essentially we were able to issue a few more licences to harvest the same number of moose that we expected to harvest over the last couple of years,"...

    If you thought that preventing gum disease is only to the benefit of your oral hygiene, think again. Gum disease, also called periodontitis, can be a prelude to more serious health problems far beyond your mouth. As it turns out, the health of your gums can dictate long term health from head to toe. Millions of Americans currently suffer from gum disease. Symptoms include swollen, red and tender gums. Gum disease is curable if caught early. Avoiding gum disease is as simple as flossing regularly, brushing your teeth twice a day, using mouthwash, and going for routine check-ups at the...

    People with both type 1 and type 2 diabetes are prone to tooth decay, and a new study from Rutgers may explain why: Reduced strength and durability of enamel and dentin, the hard substance under enamel that gives structure to teeth. Researchers induced type 1 diabetes in 35 mice and used a Vickers microhardness tester to compare their teeth with those of 35 healthy controls over 28 weeks. Although the two groups started with comparable teeth, enamel grew significantly softer in the diabetic mice after 12 weeks, and the gap continued to widen throughout the study. Significant differences in dentin...

    According to a statement released by the University of Kent, Neanderthal infants may have developed faster than modern human babies, based upon the study of a 120,000-year-old Neanderthal milk tooth discovered in what is now Croatia by an international team of researchers led by Patrick Mahoney of the University of Kent. The enamel that covers baby teeth has lines demarcating enamel produced before and after birth, and the space between the lines indicates how much enamel was grown in a single day, according to prior research. Analysis of the lines in this tooth indicates that the tooth erupted from the...
