不同表面处理对牙颈部非龋性硬化性病损粘接性能的影响

Effects of various surface treatments on the bonding efficacy of noncarious cervical sclerotic lesions

牙颈部非龋性硬化性病损(NCSL)是含有非龋性硬化性牙本质(NCSD)的牙颈部病损,大多数呈楔状或碟形,表面光亮,质硬,呈淡黄色或深棕色,好发于尖牙以及前磨牙,临床上可伴牙本质敏感,并影响美观。目前,治疗NCSL的主要方法是复合树脂直接粘接修复,但存在充填体脱落率高等临床问题。NCSL的粘接界面有NCSD和釉质2个部分,研究表明粘接修复前对这该界面进行特殊处理可以提高NCSL的粘接性能。本文对NCSL直接粘接修复术的表面处理方法及其对粘接性能的影响作一综述,为临床治疗提供参考。

Noncarious cervical sclerotic lesions(NCSL)are dental cervical lesions with noncarious sclerotic dentine(NCSD),which appears smooth,hard,and either light yellow or dark brown.Most NCSLs are wedge or dish shaped and commonly occur in canines and premolars,leading to dental hypersensitivity and aesthetic defect.The principal treatment is composite resin restoration;however,many clinical problems,such as retention loss,should not be ignored.NCSL’s bonding interface includes NCSD and enamel,and interface pre-treatment can promote the bonding effect.This review summarizes current surface treatment methods and their influence on the bonding effectiveness of NCSL to provide guidance for clinical practice.
