Conclusion
After 24 months of clinical service, all materials under investigation exhibited satisfactory restoration qualities.Class I and II restorations performed with bulk-fill composites showed similar survival rates regardless of the composite packaging and the use or non-use of SEE.Restorations performed with bulk-fill composite in syringes presented fewer marginal defects than the composite applied with the incremental technique but more than those made with bulk-fill composite in capsules.Restorations performed with SEE presented a better marginal adaptation than those with the SET strategy.
