A two-year clinical evaluation of a new calcium aluminate cement in Class II cavities.
A calcium aluminate cement (Doxa Certex, Uppsala, Sweden) has recently been developed intended for use as direct restorative filling material for posterior restorations. The material is inorganic and non-metallic and the main components are CaO, Al2O3, SiO2, and water. The aim of this study was to evaluate intra-individually the experimental calcium aluminate cement (CAC) and a resin composite (RC) in Class II restorations. Each of 57 participants received at least one pair of restorations of the same size, one CAC and one RC (Tetric Ceram). Sixty-one pairs were performed. The restorations were evaluated clinically, according to slightly modified USPHS criteria, at baseline, after 6 months, 1, and 2 years. One-hundred-and-twenty restorations were evaluated at 2 years. Postoperative sensitivity was reported for 5 restorations (2 RC, 3 CAC). Significantly better clinical durability was shown for RC. Five non-acceptable CAC restorations (8.2%) were observed at 6 months, 10 CAC (16.7%) and 2 RC (3.3%) at 12 months, and 11 CAC (18.3%) at 24 months. This resulted in a cumulative failure frequency of 43.3% for the CAC material and 3.3% for the RC material. Main reasons for failure for the CAC were partial material fracture (7), cusp fracture (5), and proximal chip fracture (6). The CAC showed a non-acceptable clinical failure rate for Class II restorations, probably caused by its difficult handling and low mechanical properties.
