The purpose of this study was to evaluate the clinical retention of three new adhesive systems in non-carious cervical lesions during a 3-year period.
The adhesive systems, a three-step (EBS/Pertac Hybrid), a one-bottle resin bonding agent (One-Step/Pertac Hybrid) and a resin-modified glass ionomer cement (Fuji II LC) were placed in 148 non-carious cervical lesions, 87 with sclerotic dentin and 61 non-sclerotic. Of the sclerotic lesions treated with the two resin bonding systems, 37 were slightly roughened with a diamond bur before conditioning. The restorations were evaluated every 6 months during a 3-year period.
All except six restorations were evaluated during the 3 years. The cumulative loss rates for EBS, One-Step and Fuji II LC were, at 1 year: 2, 24 and 2% and at 3 years: 10, 49, 7%, respectively. The one-bottle adhesive showed significantly more failures. The five lost EBS restorations were found in non-sclerotic lesions, while the three lost Fuji II LC restorations had been placed in sclerotic lesions. For the One-Step material the loss frequency for non-sclerotic versus sclerotic lesions was 31.8 and 65.2%, respectively. Slight roughening of the sclerotic dentin surfaces with a diamond bur did not increase retention of the restorations.
The three-step resin adhesive and the RMGIC showed clinically acceptable retention rates, while a high failure rate was registered for the one-bottle adhesive.
本研究旨在评估三种新型粘结系统在非龋性颈部病变中3年期间的临床保留率。
将三种粘结系统，即三步法粘结剂（EBS/Pertac Hybrid）、单瓶树脂粘结剂（One-Step/Pertac Hybrid）和树脂改性玻璃离子水门汀（Fuji II LC）应用于148例非龋性颈部病变，其中87例为硬化牙本质病变，61例为非硬化牙本质病变。在使用两种树脂粘结系统治疗的硬化病变中，37例在预处理前用金刚砂车针轻度粗糙化处理。在3年期间每6个月对修复体进行评估。
除6个修复体外，所有修复体均在3年内进行了评估。EBS、One-Step和Fuji II LC在1年时的累积脱落率分别为2%、24%和2%，在3年时分别为10%、49%、7%。单瓶粘结剂的失败率明显更高。5个脱落的EBS修复体见于非硬化病变，而3个脱落的Fuji II LC修复体置于硬化病变中。对于One-Step材料，非硬化病变与硬化病变的脱落频率分别为31.8%和65.2%。用金刚砂车针对硬化牙本质表面进行轻度粗糙化处理并未提高修复体的保留率。
三步法树脂粘结剂和树脂改性玻璃离子水门汀显示出临床可接受的保留率，而单瓶粘结剂的失败率较高。
