To evaluate the long-term clinical performance of heat-cured high-viscosity glass ionomer (GIC) and posterior composite resin (CR) restorations in primary molars over a 3-year period.
Photographs and radiographs of EQUIA GIC and Filtek™ P60 restorations were assessed. Study sample is comprised of healthy preschool/school children with proximal surface caries in primary molars.
70 GI restorations were placed in 45 patients (aged 78 months ± 25) and were evaluated at 33 months ± 7. 61 composite resin restorations were placed in 42 patients (age 82 months ± 19) and were evaluated at 39 months ± 13. GI restorations failure was 17.1%, a significantly greater rate compared with 4.9% in the CR group. GI failures were due to either significant loss of the restoration or to loss of marginal ridge integrity. CR failures were due to loss of marginal ridge integrity.
Both GI and CR restorations were clinically successful during a 3-year period. GI restorations may be considered as an intermediate-lasting restoration option for proximal lesions in primary molars, with 83% of the restorations functioning up to 36 months. CR restorations showed a higher success rate than GIC during the same period.
评估热固化高粘度玻璃离子水门汀（GIC）和后牙复合树脂（CR）修复乳牙3年的长期临床性能。
对EQUIA GIC和Filtek™ P60修复体的照片和X线片进行评估。研究样本包括患有乳牙邻面龋的健康学龄前/学龄儿童。
45例患者（年龄78个月±25个月）共放置70个GIC修复体，在33个月±7个月时进行评估。42例患者（年龄82个月±19个月）共放置61个复合树脂修复体，在39个月±13个月时进行评估。GIC修复体的失败率为17.1%，显著高于CR组的4.9%。GIC修复体失败的原因是修复体严重磨损或边缘嵴完整性丧失。CR修复体失败的原因是边缘嵴完整性丧失。
GIC和CR修复体在3年期间临床效果均良好。GIC修复体可被视为乳牙邻面龋的一种中期持久修复选择，83%的修复体可使用至36个月。同期CR修复体的成功率高于GIC。
