About 60 to 90% of school-age children and 92% of adults in the U.S. have experienced tooth decay. “Only 2% of people at all ages living in Nigeria had tooth decay when their diet contained almost no sugar, around 2g per day. This is in stark contrast to the USA, where 92% of adults have experienced tooth decay,” study author Aubrey Sheiham, emeritus professor of Dental Public Health at University College London, said in a statement.
Chief Investigator, Centre for Research Excellence in Primary Oral Health Care, and an employee of the Universities of Tasmania and Adelaide, Dr Leonard Crocombe, says the main reason there are so few dentists in the bush is they can’t make money.
“You need at least 3,000 patients for a dentist to make money, more than you’d need for a doctor,’ he says.
Even if there are enough patients, low incomes in the bush mean many rural residents can’t afford dental care even if it is on offer.
"We think goosing up the Bmp6 signal doubles the number of teeth,” Miller said. “This fairly simple genetic basis for gaining something new, such as teeth, is surprising. A very tiny change in the regulator has a large effect.”
“We found that freshwater-derived sticklebacks keep making teeth constantly and never seem to slow down, whereas the ancestral form stops making more teeth,” he said. “While biologists have known for a long time that sharks and some fish continually replace their teeth, almost nothing was known until now about the genetic basis of evolved changes in tooth patterning.”
Mr Van Nierop claims to have killed his wife in 2006, two years before he was persuaded to move to the remote rural area of Chateau-Chinon in central France.
He was initially welcomed by locals sorely lacking in medical services. But concerns soon started to mount as patients reported broken jaws, recurrent abscesses, septicemia and healthy teeth being pulled out, French media reported.
Mr Van Nierop has also been charged with fraud over claims he tried to rip off customers.
“He said he had done 17 treatments on 17 different teeth for my wife in 10 minutes, as well as charging for a tooth that had been pulled out 10 years earlier,” one local, Gerard Martin, told AFP in July.
Danaher, an industrial conglomerate with products ranging from laboratory equipment to water-treatment chemicals, is buying a business whose sales still haven’t recovered from the recession and financial crisis that began in 2008. After peaking at 90.75 francs in 2007, Nobel Biocare has traded below 20 francs for more than three years. As unemployment soared, people cut back on implants, which often aren’t covered by insurance.
“Nobel had a very rich valuation, so the upside was limited,” said Oliver Metzger, an analyst at Commerzbank AG in Frankfurt. He said he doesn’t expect rival bids. “For Nobel Biocare shareholders, it’s still an attractive price compared with the share price of recent years.”
Brushing is important for reasons beyond fresh breath. Skip a session, and you’re on your way to encouraging the growth of bacterial buildup in the form of plaque, which can lead to cavities and gum disease.
“In the middle of the day, [run your tongue] across your teeth right around the gum line. You’ll find something sticky or fuzzy,” Deepinder “Ruchi” Sahota, DDS, a dentist in Fremont, California, and a spokesperson for the ADA, tells The Huffington Post. “That’s plaque.”
