摘要
過去二十年來，在口腔保健上發生了重大的變化。在ten Cate 1999年的資料中顯示，由於氟化物的廣泛使用，添加在牙膏與漱口水中，明顯地改善了齲齒的罹患率，也因此牙齒保健的方向，由齲齒的填補治療，進展到齲齒的預防與牙周病的治療與保健。加上口腔衛生觀念的覺醒與牙周治療的技術發展迅速，牙齒在口腔內的使用年限也隨民眾壽命的延長而漸漸增加。而牙齒結構曝露在口腔中，所接受來自環境中的物理化學刺激也隨之增多，包括飲料的酸性腐蝕與不當清潔方式之下，使得牙齒不同層次的結構更容易遭受破壞。牙齒預防保健的觀念，也由牙齒結構的填補保存轉移到結構的流失預防。本文將由探討牙釉質的形成，到牙釉質與牙本質的互相誘導分化，再到牙齒酸蝕的臨床表徵，以及食物造成的影饗，與日後如何預防牙齒酸蝕上，做一個系列與簡短的介紹，也藉此作爲臨床醫師的鑑別診斷的依據。

In the past decade, there is a huge change in oral care. According to ten Cate in 1999, data didshow much improvement in incidence of caries because of widely used fluoride compounds added todifferent toothpastes and mouthrinses. It drives a different way of oral care from caries control towardprevention of caries and treatment of periodontal disease. Besides the enhancement of oral hygiene aswell as progress of periodontal treatment, functional use of teeth seems getting longer along with theincreasing age. Due to increasing physical and chemical irritations from outside environment such aserosive drinks or incorrect brushing, tooth structures become easily destructed with increasing exposuretime of tooth inside the mouth. The concept of preventive care of tooth shifts from re-construction oftooth to prevention of tooth structure loss. This article will first discuss the formation of enamel as wellas the interaction between the inductive formation between dentin and enamel. Fruther it brieflyexplore the clinical signs of tooth erosion and the different influence caused by foods to the correct wayto prevent the tooth erosion and preserve the tooth structure. It help clinical dentist make thedifferentiation diagnosis and perform the proper treatment.
