To verify the clinical behavior of two resin-based composites with different Young's modulus (AElite Fil and Elite Flo) in the restoration of carious and non-carious cervical lesions after 48 months of clinical service.
116 restorations with the two different materials (60 with AElite Fil and 56 with AElite Flo) were performed in 15 patients and controlled for 48 months. Retention rate and USPHS criteria were recorded at 6, 12, 24, 36 and 48 months.
The retention rate was 66% for AElite Fil in carious and non-carious lesions and 65 and 47% for AElite Flo in carious and non-carious lesions respectively at 48 months. A decrease of quality of restorations in time was recorded with all USPHS criteria, with no statistically significant difference between materials tested.
验证两种具有不同杨氏模量的树脂基复合材料（AElite Fil和Elite Flo）在临床使用48个月后对龋性和非龋性颈部病变修复的临床性能。
对15例患者进行了116次使用两种不同材料的修复（60次使用AElite Fil，56次使用AElite Flo），并进行了48个月的观察。在6、12、24、36和48个月时记录保留率和美国公共卫生服务（USPHS）标准。
在48个月时，AElite Fil在龋性和非龋性病变中的保留率为66%，而AElite Flo在龋性和非龋性病变中的保留率分别为65%和47%。根据所有USPHS标准，修复体质量随时间下降，所测试材料之间无统计学显著差异。
