世界卫生组织为改变农村及不发达地区龋病充填率极低的状况,推荐使用简单手工器械及改进的玻璃离子材料,作为充填材料和封闭剂进行预防性充填,该技术被称为非创伤性充填治疗(ART)技术[1]。随着医学模式的转变及“微创概念”深入人心,龋齿治疗的趋势逐渐向微创发展,即无论龋损大小,都尽可能保存天然牙体组织,对已有龋洞进行最小的外科治疗,将对牙 In order to change the extremely low caries filling rate in rural and underdeveloped areas, WHO recommends the use of simple manual instruments and improved glass ionomer materials as prophylactic filling materials and sealants.
