ClinConnect Summary

1. With limited evidence-based information about the clinical performance of resin composite in class II cavities. it is beneficial to compare the newly introduced "snow-plow' technique using a randomized clinical trial to test the null hypothesis that this new technique has the same clinical performance.
2. The comparator will be the bulk fill technique as an alternative to the conventional layering technique. This is because it has shown lower polymerization shrinkage when comparing it to the conventional composite. Bulk fill has reduced the chair time for the patient. It is done by the a...
