FEAR FACTOR Twelve per cent of UK adults would rather hold a tarantula than visit the dentist according to YouGov research. A third of people who have ever visited the dentist said they felt scared beforehand, with the top deterrents being potentially undergoing a dental procedure (31 per cent) and fear of needles/injections (30 per cent). Lack of trust, relinquishing control, and the unknown were among the fear factors highlighted.


BUG KILLERS Dutch researchers at the University of Groningen say they have found a way to create 3D-printed teeth that kill bacteria without harming human cells. They told New Scientist they could embed antimicrobial quaternary ammonium salts into existing dental resin polymers. The bacterial matrix was then used to print various dental objects. They hope the tech will be ready for clinical use after testing.


DENTAL RECORD Mumbai surgeons extracted a record-breaking 232 teeth from the mouth of a 17-year-old boy in a seven-hour operation. He had severe pain for 18 months and was diagnosed with a very rare complex composite odontoma, a type of benign tumour where a single gum forms lots of teeth. The boy is now pain-free and has 28 teeth.
