Influence of resin coating on bond strength of self-adhesive resin cements to dentin

Abstract

This study evaluated the effect of resin coating (COA) on dentin bond strength (BS) of five resin cements (RC). Ten groups were tested, according to RC and COA combinations. RCs were applied onto prepolymerized resin discs, which were bonded to dentin surfaces. Teeth were stored in water for 24 h, subjected to 5,000 thermocycles and sectioned to obtain beams, which were tested in tension. The COA increased the BS for Panavia F2.0, RelyX Unicem, and RelyX Unicem 2, whereas no changes in BS were observed for two other RCs; Clearfil SA Cement, which showed the lowest BS among groups with COA and G-Cem, which showed the highest BS among RCs without COA. COA can increase the BS of RC depending on the type of RC.

Immediate Dentin Sealing: A Literature Review

“… Rocca et al 2015 141 Review - - IDS is a crucial step of the indirect restoration fabrication procedure. Giannini et al 2015 74 In vitro Bond strength, Cement type Evaluated the effect of IDS (Clearfil SE Bond + Clearfil Majesty Flow) on the dentin bond strength of five resin cements (RelyX Unicem, RelyX Unicem 2, Clearfil SA Cement, G-Cem, Panavia F2.0). The increase in bond strength was dependent upon the resin cement type.…”

The effect of temporary sealing materials and cleaning protocols on the bond strength of resin cement applied to dentin using the resin-coating technique

“…In the resin-coating technique, the dentin and enamel surfaces that are exposed after cavity preparation are coated with a thin film of a coating material or a dentin bonding system combined with a flowable composite resin 1) . Several studies have demonstrated that the resin-coating technique protects the dentin and pulp [2][3][4] through the formation of a hybrid layer, improving the resin cement-dentin bonding in an indirect restoration procedure [5][6][7][8][9] and reducing the pain caused by external physical stimuli as it seals the dentinal tubules [10][11][12] .…”

Concept and clinical application of the resin-coating technique for indirect restorations

“…It also facilitates the removal of temporary bonding material adhering to the side of the abutment tooth. The resin-coating technique is also effective for self-adhesive cement, which has become more widely used in recent years 39) . In Japan, where society is aging rapidly, the problem of root caries needs to be addressed; the resin-coating technique may be useful for this purpose in clinical applications.…”
