Four hundred and thirty nine chemical-cured composite resin restorations were placed in the anterior teeth of 86 patients treated in a private dental practice. Four anterior resins were used, and placement was performed with acid etching and appropriate enamel bonding resins. Assessments were made of the handling characteristics, condition of the gingiva, surface staining, marginal staining, color deterioration, and of the longevity of the four materials. Clinical deterioration rates and failures of the different types of composites were evaluated over periods of up to five years. Although all the assessed clinical factors deteriorated with time, there were very few unsatisfactory rating scores. Most of the composite restorations performed well over the study. Eight per cent of the restorations failed during the study. Class IV preparations showed the highest restoration failure rates.
439颗化学固化复合树脂修复体被放置在一家私人牙科诊所治疗的86名患者的前牙中。使用了四种前牙用树脂，并通过酸蚀和合适的牙釉质粘结树脂进行修复体放置。对这四种材料的操作特性、牙龈状况、表面染色、边缘染色、颜色恶化情况以及使用寿命进行了评估。在长达五年的时间里评估了不同类型复合材料的临床恶化率和失败情况。尽管所有评估的临床因素都随时间而恶化，但不满意的评分很少。在研究期间，大多数复合树脂修复体表现良好。8%的修复体在研究期间失败。IV类修复体显示出最高的修复失败率。
