Technique on restoring sub-gingival cervical lesion.

abstract：CLINICAL RELEVANCE:The degree of conversion of contemporary universal adhesives positively correlates with the bond strength to dentin. The correlation is more marked after thermocycling, suggesting that a high degree of conversion is required for long-term dentin bonding durability. SUMMARY:Purpose: The objectives of...
