電動牙刷差別只在快慢The difference of electric toothbrushes is only in the speed

電動牙刷差別只在快慢 【詹建富】電動牙刷問世，刷牙進入電動時代，甚至還有所謂音波電動牙刷，以及內建藍牙裝置的導航電動牙刷，號稱讓刷牙變得輕鬆省事。問題是電動牙刷的潔牙效果會比一般的手動牙刷好嗎？ 台北醫學大學附設醫院牙周病科主任呂炫指出，在門診中，常有病人問起： 「電動牙刷有比較好嗎？ 」他總是拿腳踏車和機車做比喻，如果以目的地來說，兩者都可到達，差別只在快慢而已；同樣的，若採用相同的刷牙手法，電動牙刷和傳統牙刷的清潔效用也都差不多，唯一的差別在於電動牙刷瞬間轉動次數非常快，可大幅降低潔牙時間。 不過，呂炫指出，部分民眾常以為電動牙刷可以自動刷牙，刷牙動作反而不正確，效果反而差。 用電動牙刷刷毛仍應輕輕接觸到牙齒表面，然後輕輕地以圓弧方式擺動震動中的牙刷頭，否則刷不到正確的位置，根本無法有效去除牙菌斑。 另外，目前雖有兒童專用的電動牙刷，握把非常輕巧，但呂炫認為，兒童使用電動牙刷還是有其年齡上的限制，最好是6至8歲以上及單手能有效握住牙刷的握把，家長應確定孩子已習慣一般牙刷，再使用電動牙刷。 2008-09-19 The difference of electric toothbrushes is only in the speed Zhan Jian Fu】 【electric toothbrushes come out, brush their teeth into the electric age, and even the so-called acoustic electric toothbrush, as well as built-in Bluetooth navigation devices for electric toothbrush, so-called brush easily become easier.
