摘　　要：超声波作为一种新的治疗手段近年来已被广泛运用于牙根尖倒预备,成功地解决了许多传统方法无法解决的问题,显示出明显的优越性,大大提高了牙髓外科治疗的成功率。然而,该技术也存在一定的局限性,学者们对超声牙根尖倒预备后牙根切面出现的微裂现象进行了广泛研究。下面就该方面的研究进展作一综述。Ultrasonic root-end preparation techniques have recently been introduced and revolutionized the field of endodontic surgery. The ultrasonic devices permit the preparation of conservative and straight cavities, However, investigators have different reports that microfractures can occur due to the vibratory action of this instruments. This article reviews the literature on microcracks associated with ultrasonic root-end preparation.
