Purpose:
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.
Methods:
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.
Results:
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.
