Immediate dentin sealing for indirect bonded restorations

Abstract

Purpose: The aim of this article is to review available literature on the clinical procedure of immediate dentine sealing for indirect bonded restorations. Study selection: More than 40 articles reporting the technique, studies, outcomes, etc. were reviewed after PUBMED/MEDLINE search, most of them addressing the specific situation of dentin bonding for indirect restorations. Results: It is known that tooth preparation for indirect bonded restorations can result in significant dentin exposures. Immediate application and polymerization of the dentin bonding agent to the freshly cut dentin, prior to impression making is therefore recom- mended by some authors. Literature indicates that this procedure, immediate dentine sealing (IDS), appears to achieve improved bond strength, fewer gap formations, decreased bacterial leakage, and reduces post-cementation sensitivity. This rational approach to adhesion is also reported to have a positive influence on tooth structure preservation, patient comfort, and long term survival of indirect bonded restorations. Conclusion: In the extensive literature regarding advantages of using IDS technique signifi- cant differences have been shown when compared to Delayed Dentine Sealing. Although more research is required in this field, presently there are NO scientific reasons not to recommend IDS in routine practice.
