修复前牙釉色溷浊也是临床上有待解决的一个问题。过去常用的倒凹(undercuts)和钉道就位(pins)的方法常使患牙容易折断或损及牙髓。本文介绍应用涂膜材料处理釉色溷浊对青年的恒牙来讲是一个简单而有效的方法。具体的操作是:先将患牙用橡牙障隔离,然后磨去釉色溷浊的釉质至深度约0.5毫米左右。吹干患牙,再用棉球蘸酸性处理液进行酸蚀一分半钟,酸蚀面可延伸超过周围正常的釉质1—2毫米。用水洗净酸蚀
To repair the anterior glaze turbidity is also a problem to be solved clinically. In the past, undercuts and pins were often used to break the affected tooth or damage the pulp. This article describes the application of coating material processing glaze turbid turbid permanent teeth for youth is a simple and effective method. The specific operation is: First, the affected teeth with rubber barrier isolation, and then rubbed glaze turbid enamel to a depth of about 0.5 mm. Dried teeth, and then dipped in acid solution cotton acid etching for one and a half minutes, the etching surface can extend beyond the surrounding normal enamel 1-2 mm. Wash the acid with water
