introdouction: esthetic demands of patients have led to the introduction of tooth-colored restorations wherecomposite resins are bonded to the enamel using acid etch techniques. total etch adhesion systems are still considered as the gold standard among bonding systems. however, clinicians have a tendency to use adhesive systems with simpler application procedures. the aim of the present study ...

The shear bond strength (SBS) of a light-cured, resin-reinforced glass ionomer and a composite adhesive in combination with a self-etching primer was compared after different setting times to evaluate when orthodontic wires could be placed. Additionally, the fracture site after debonding was assessed using the Adhesive Remnant Index (ARI). Eighty freshly extracted human premolars were used. Twe...

UNLABELLED Interface integrity can be maintained by setting the composite in a layering technique and using liners. OBJECTIVE The aim of this in vitro study was to verify the effect of resin-modified glass-ionomer cement (RMGIC) lining and composite layering technique on the bond strength of the dentin/resin adhesive interface of lateral walls of occlusal restorations. MATERIAL AND METHODS ...

AIM This study aimed to evaluate the microleakage of Class V restorations filled with a 7th-generation self-adhesive composite. MATERIALS AND METHODS In 40 permanent premolars and 80 primary canines, 160 Class V cavities were prepared, which were filled with four restorative materials (n of each material=20 permanent and 20 primary restorations): control: nonbonded composite (Heliomolar), GI:...

OBJECTIVE This in vitro study aimed to evaluate the influence of different surface treatments, 3 luting agents and thermocycling on microtensile bond strength (µTBS) to zirconia ceramic. MATERIAL AND METHODS A total of 18 blocks (5x5x4 mm) were fabricated from zirconia ceramic (ICE Zirkonia) and duplicated into composite blocks (Alphadent). Ceramic blocks were divided into 3 groups (n=6) acco...

OBJECTIVE The purposes of this research were to (1) compare the shear-peel bond strength (SPBS) of a band of a fixed space maintainer (SM) cemented with five different adhesive cements; and (2) compare the survival time of bands of SM with each cement type after simulating mechanical fatigue stress. MATERIALS AND METHODS Seventy-five teeth were used to assess retentive strength and another 50...

Objectives The present study investigated the effect of cements on fracture resistance of monolithic zirconia crowns in relation to their compressive strength. Materials and methods Four different cements were tested: zinc phosphate cement (ZPC), glass-ionomer cement (GIC), self-adhesive resin-based cement (SRC) and resin-based cement (RC). RC was used in both dual cure mode (RC-D) and chemical...
