Cervical abrasion and erosion lesions were restored with composite resin restorations bonded with four different dentin-bonding resins, an enamel-bonding resin, or restorations of a glass ionomer cement. The long-term clinical retention of the restorations were evaluated during a 4-year period. The surrounding enamel was not acid-etched. Four cleaning methods for dentin pretreatment were used to study their effects on the bonding between dentin and the restorative materials. The dentin was treated with either (1) etching for 60 seconds or (2) 15 seconds with 37% phosphoric acid, (3) cleaning with 5% sodium hypochlorite (NaOCL) for 20 seconds, or (4) cleaning with Tubulicid etchant for 60 seconds. None of the composite resin restorations, regardless of pretreatment or bonding method, showed acceptable restorations. All glass ionomer cement restorations were retained after pretreatment with Tubulicid etchant and 5% NaOCL after a 6-month period. Full acceptance, in other words, 3 year retention, was reached only after pretreatment with NaOCL.
使用四种不同的牙本质粘结树脂、一种釉质粘结树脂或玻璃离子粘固剂修复体对宫颈磨损和糜烂病变进行复合树脂修复。在4年期间评估修复体的长期临床保留情况。修复体周围的釉质未进行酸蚀处理。使用四种牙本质预处理清洁方法研究它们对牙本质与修复材料之间粘结的影响。牙本质分别采用以下方法处理：（1）用37%磷酸酸蚀60秒；（2）用37%磷酸酸蚀15秒；（3）用5%次氯酸钠（NaOCL）清洗20秒；（4）用Tubulicid蚀刻剂清洗60秒。无论预处理或粘结方法如何，所有复合树脂修复体均未显示出可接受的修复效果。在使用Tubulicid蚀刻剂和5% NaOCL预处理6个月后，所有玻璃离子粘固剂修复体均得以保留。只有在使用NaOCL预处理后，修复体才能完全被接受，即保留3年。
