PREHISTORIC PAIN Neanderthals may have treated toothache using plants, according to research in the journal Nature. Investigation of the ancient remains of a man found in Spain suggest he ate poplar, which contains the active ingredient of aspirin, to treat an abscess. His dental plaque also had a natural form of penicillin, 40,000 years before its discovery. Source: CNN


BITTER PILL Scientists have embedded chewing gum with a special biosensor to detect peri- implant disease. Specific enzymes occurring in disease-sufferers trigger the release of a bitter taste to alert the chewer to the problem. But Nature Communications reports it’s


so far only been tested using an “artificial tongue” rather than real patients.


TEETH INFLATION The amount left to UK children by the tooth fairy has increased by five per cent in the past year, rising to an average £1.49 per tooth. Research by SunLife found London children get the most at £1.88 per tooth while those in the South West get the least at £1.18.


FROM THE MUSEUM The use of ether for dental extraction came back into fashion once clinicians


realised the dangers of the once-popular chloroform. John Clover designed the first regulating ether inhaler in 1877 as an alternative to less scientific methods of ad- ministering, via a soaked towel or inhaling through a cone. The gadget was widely used and modified thanks to its effectiveness and speedier patient recovery times.
