Tensile bond characteristics between composite resin and resin-modified glass-ionomer restoratives used in the open-sandwich technique

Abstract

The use of bonding agent improved the CR/RMGIC bond by tensile strength and strain tests.

Effect of self-etching dual-curing universal adhesive system application on bond strength of dentin resinous liners dentin

“…In fact, a study proposed the use of an adhesive system between the liner and composite to improve the bonding between them. [29] Based on that, it is questioned whether the set liner-composite would rip the liner material off from the dentin. Therefore, the use of an adhesive system prior to the application of the liner could also help to improve the bonding between the material and dentin, avoiding this problem.…”

Marginal Adaptation Evaluation of Biodentine and MTA Plus in “Open Sandwich” Class II Restorations

“…Open sandwich technique, i.e., placing a glass ionomer liner up to the cavity margin, has been advocated in the past to negate the effect of shrinkage stresses at the gingival margin . This technique is especially beneficial in cases with caries extending onto the root surface or in patients at high caries risk .…”

“…Tantbirojn and colleagues reported that glass ionomer liners, placed in an open sandwich technique, exhibited pronounced inhibition zones at the dentin margin and lowered the amount of mineral loss in the vicinity of 0.25 mm from the restoration interface under in vitro demineralization challenge. Glass ionomer has mechanical properties comparable with dentin and is widely used as dentin substitute under restorations . Development of light cured glass ionomer gave the clinician a control over its setting time and allowed its use as a dentin substitute in open sandwich restorations.…”
