Abstract

BACKGROUND

Long-term prospective survival studies of resin-modified glass ionomer cements (RMGICs) and polyacid-modified resin composites (compomers) placed in non-carious cervical lesions (NCCLs) are lacking from general dental practice. Short-term studies have shown an unsatisfactory clinical performance for several materials.

METHODS

One practitioner placed 87 compomer (Compoglass, Vivadent-Ivoclar) and 73 encapsulated RMGIC (Fuji II LC, GC Int.) restorations in NCCLs for 61 adults. Compoglass was placed using SCA primer, and Fuji II LC using GC Dentin Conditioner. No cavity preparation was undertaken. The Kaplan-Meier method was used for estimating the cumulative survivals for those restorations that were replaced, with the probability level set at alpha = 0.05 for statistical significance.

RESULTS

Restorations were judged unsatisfactory (by the practitioner and the subjects) because of surface and marginal loss of material (68.8 per cent), dislodgement (18.8 per cent) and discoloration (12.4 per cent), these modes being similar for both materials (P = 0.35). Unsatisfactory restorations were replaced in 121 (75.6 per cent) instances. After periods of up to five years, cumulative survival estimates were 14.9 (5.8 Standard Error) per cent for Compoglass and zero per cent for Fuji II LC (P = 0.74). Median survivals were 30 months for Compoglass and 42 months for Fuji II LC.

CONCLUSION

Both materials had high long-term unsatisfactory performances when placed in non-prepared NCCLs in a general dental practice.

摘要

背景

普通牙科实践中缺乏对用于非龋性颈部病变（NCCL）的树脂改性玻璃离子水门汀（RMGIC）和聚酸改性树脂复合体（复合体）的长期前瞻性生存研究。短期研究表明几种材料的临床性能不尽人意。

方法

一名从业者为61名成年人的NCCL放置了87个复合体修复体（Compoglass，Vivadent - Ivoclar）和73个封装的RMGIC修复体（Fuji II LC，GC Int.）。Compoglass使用SCA底漆放置，Fuji II LC使用GC牙本质调节剂放置。未进行窝洞预备。采用Kaplan - Meier方法估计那些被替换修复体的累积生存率，将概率水平设定为α = 0.05以具有统计学意义。

结果

修复体因材料表面和边缘损耗（68.8%）、移位（18.8%）和变色（12.4%）而被判定为不满意（由从业者和受试者判定），这两种材料的这些情况相似（P = 0.35）。121例（75.6%）不满意的修复体被替换。经过长达五年的时间，Compoglass的累积生存估计为14.9%（标准误5.8），Fuji II LC为0%（P = 0.74）。Compoglass的中位生存期为30个月，Fuji II LC为42个月。
