新的蛀牙療法即將讓填補材料成為歷史
科學家已經研發出全新的無痛補牙術，
讓治療蛀牙不再是挖挖補補，還要挨麻醉針的苦差事。
科學家已經研發出全新的無痛補牙術，
讓治療蛀牙不再是挖挖補補，還要挨麻醉針的苦差事。
倫敦國王學院發展出一套全新的牙齒重建技術。
該技術捨棄傳統的挖補方式，而是刺激牙齒自行重新生長。
傳統的蛀牙治療是用電鑽清除壞死的部分，
再用汞合金、複合樹脂等材料進行填補。
新療法─牙齒再礦化電流加速術(英文縮寫:EAER)是將人體內原有的鈣質和磷酸鹽加速轉移到受損的部位，進而達到修復的效果。

新療法分成兩個步驟。
一.首先牙醫師會清除已經蛀掉的法瑯質。
二.利用微弱的電流將礦物質搬到需要修復的部份。
這項技術將在三年內普及。國王學院牙科研究院的耐吉爾‧皮特斯教授表示：
我們時下治療牙齒的方式並不理想。
當患者接受填補術治療之後，就會進入挖挖補補的惡性循環；
最後連填補術也於事無補。新的療法不但能以更溫和的方式對待患者的牙齒，
它還是目前經濟效益最高的做法。
因為它除了能治療蛀牙之外，還能延伸成牙齒美白療程。

No more fillings as dentists reveal new tooth decay treatment

Scientists have developed a new pain-free filling that allows cavities to be repaired without drilling or injections.
The tooth-rebuilding technique developed at King's College London does away with fillings and instead encourages teeth to repair themselves.
Tooth decay is normally removed by drilling, after which the cavity is filled with a material such as amalgam or composite resin.
The new treatment, called Electrically Accelerated and Enhanced Remineralisation (EAER), accelerates the natural movement of calcium and phosphate minerals into the damaged tooth.
A two-step process first prepares the damaged area of enamel, then uses a tiny electric current to push minerals into the repair site. It could be available within three years.
Professor Nigel Pitts, from King's College London's Dental Institute, said: "The way we treat teeth today is not ideal. When we repair a tooth by putting in a filling, that tooth enters a cycle of drilling and refilling as, ultimately, each 'repair' fails.
"Not only is our device kinder to the patient and better for their teeth, but it's expected to be at least as cost-effective as current dental treatments. Along with fighting tooth decay, our device can also be used to whiten teeth."
A spinout company, Reminova, has been set up to commercialise the research. Based in Perth, Scotland, it is in the process of seeking private investment to develop EAER.
The company is the first to emerge from the King's College London Dental Innovation and Translation Centre, which was set up in January to take novel technologies and turn them into new products and practices.
King's College is a participant in MedCity, a project launched by the London mayor, Boris Johnson, to promote entrepreneurship in the London-Oxford-Cambridge life sciences "golden triangle".
The chairman of MedCity, Kit Malthouse, said: "It's brilliant to see the really creative research taking place at King's making its way out of the lab so quickly and being turned into a new device that has the potential to make a real difference to the dental health and patient experience of people with tooth decay."
