فرشة أسنان مبتكرة تصعق البكتيريا

ما يعرفه ريفو عن الخبر

أظهرت تجارب على متطوعين أن فرشاة أسنان مبتكرة ذات شعيرات كهرضغطية تقلل من تراكم الجير ونزيف اللثة.
تولد شعيرات الفرشاة شحنات كهربائية تنتج أنواعا من الأكسجين تتلف أغشية خلايا البكتيريا أثناء التنظيف.
أثبت الباحثون أن الفرشاة غير سامة للخلايا البشرية ولا تضر بسطح السن.
لا تزال هناك تساؤلات حول سلامة الفرشاة المبتكرة على المدى الطويل وتكلفتها المادية.

ابتكر علماء من جامعة بكين فرشاة أسنان تعمل من دون بطارية، ولكنها تولد شحنة كهربائية عن طريق تغيير شكل شعيراتها أثناء التنظيف، ما يؤدي إلى قتل البكتيريا.
