Five dentine adhesive systems (four resin-based dentine bonding agents and one polyacid-modified composite resin) were evaluated clinically in non-undercut Class V 'abrasion' lesions. The loss rate of restorations varied from 26 per cent to 95 per cent at three years among the five systems. Products which bonded to dentine via the hybrid layer were markedly more retentive than those which were designed to bond chemically. The two products which attempted to achieve bonding between their carboxyl groups and dentinal calcium were hydrophilic, which probably contributed to their lack of success.
对五种牙本质粘结系统（四种树脂基牙本质粘结剂和一种聚酸改性复合树脂）进行了临床评估，用于非倒凹的V类“磨损”病变。在这五种系统中，修复体在三年时的脱落率从26%到95%不等。通过混合层与牙本质粘结的产品明显比那些设计为化学粘结的产品更具固位力。两种试图通过其羧基与牙本质钙实现粘结的产品具有亲水性，这可能是它们不成功的原因。
