Clinical evaluation of a new resin composite crown system to eliminate postoperative sensitivity.
This study evaluated the long-term clinical performance of a new resin composite restorative system with a 4-META dentin-bonding agent to seal complete crown preparations prior to temporization and after permanent luting with a companion resin cement. Complete-coverage crown preparations were completed on 33 vital teeth and 5 nonvital teeth (control). The new restorative material demonstrated satisfactory clinical performance for the 3-year test period. The dentin-bonding agent and its companion resin cement successfully eliminated postoperative hypersensitivity in 100% of the prepared vital teeth over the 3-year term, suggesting excellent seal of dentinal tubules exposed by the complete-crown preparations.
