Objective: The objective of this randomized controlled prospective trial was to evaluate the durability of a low shrinkage and HEMA/TEGDMA-free resin composite system in posterior restorations in a 6-year follow up.
Material and methods: 139 Class II restorations were placed in 67 patients with a mean age of 53 years (range 29-82). Each participant received at random two, as similar as possible, Class II restorations. In the first cavity of each pair the HEMA/TEGDMA-free resin composite system was placed with its 3-step etch-and.rinse adhesive (cmf-els). In the second cavity a 1-step self-etch adhesive was used (AdheSe F-els). The restorations were evaluated using slightly modified USPHS criteria at baseline and then yearly during 6 years. Caries risk and parafunctional habits of the participants were estimated.
Results: Three molar teeth showed mild post-operative sensitivity during 3 weeks for temperature changes and occlusal forces. After 6 years 134 Class II restorations were evaluated. 21 restorations, 8 cmf-els (11.4%) and 13 ASE-els (20%) failed during the 6 years (p<0.0001). The annual failure rates were for 1.9% and for 3.3%, respectivally. The main reasons for failure were fracture followed by recurrent caries. Most fractures and all caries lesions were found in high risk participants.
Significance: The tested Class II resin composite restorations performed with the new HEMA/TEGDMA-free low shrinkage resin composite system showed good durability
