OBJECTIVE This study was designed to evaluate the effects of type I collagen degradation on the durability of three adhesive systems in the early phase of dentin bonding. METHODS Bonded dentin specimens were prepared using three different types of adhesive systems. Micro-tensile bond strength and degradation of collagen were tested before, and after 1 month or 4 months of aging in artificial ...

OBJECTIVES This study aimed to compare the durability of four adhesive systems by assessing their microtensile bond strength (MTBS) and microleakage during six months of water storage. MATERIALS AND METHODS A total of 128 human third molars were used. The adhesives tested were Scotch Bond Multipurpose (SBMP), Single Bond (SB), Clearfil-SE bond (CSEB), and All-Bond SE (ABSE). After sample prep...

The European Lime Association (EuLA) have instigated a project to identify and quantify the benefits associated with the addition of hydrated lime to cement based mortars, and more importantly, filling the gaps that exist in the evidence in respect of the benefits of hydrated lime additions to workability, bond strength development, durability and in addition the modes of failure of mortars whn...

flexibility as an ability to respond to changing circumstances is one of the vital characteristics of the natural and built environment. during the contemporary era, diversity of methods relating the architectural flexibility execution are suggested. but along with contemporary conceptual approaches toward pluralism and uncertainty, it seems that the multiplicity of approaches toward flexibilit...

OBJECTIVE To compare different surface treatments of lithium disilicate-based ceramic on bond strengths to composite. METHODS Lithium disilicate-based ceramic microbars (1 mm × 1 mm × 6 mm) were produced and abraded using diamond (D) or CoJet sandblasting (C), etched using phosphoric acid (P) or hydrofluoric acid (H) and silanised (S). A total of 12 surface treatments were adopted: D, DP, DH,...
