Introduction: Recent advances in the field of material sciences have opened up a new horizon of options for bonding agents that can be used efficiently in orthodontics. The purpose of this study was evaluate and compare the shear bond strength (SBS) of the traditionally used Transbond XT and a newer nano-filled material Prime and Bond NT. Materials and methods: Sixty freshly extracted maxillary...

This in vitro study evaluated the bond strength of adhesive restorative materials to sound and eroded dentin. Thirty-six bovine incisors were embedded in acrylic resin and ground to obtain flat buccal dentin surfaces. Specimens were randomly allocated in 2 groups: sound dentin (immersion in artificial saliva) and eroded dentin (pH cycling model - 3× / cola drink for 7 days). Specimens were then...

background and aims: new dentin bonding agents and techniques have been developed to reduce microleakage and create higher bond strength. this in-vitro study compared the microleakage of three resin-based adhesives versus a gic-based adhesive on class v composite restorations.  materials and methods: class v cavities were prepared on the buccal surfaces of 72 sound premolars, randomly assigned ...

In this study; plates were produced from wood added PLA based materials using 3D printers, which is one of the additive manufacturing methods. After applying mechanical abrasion (sanding), surface preparation methods, to surfaces plates, adhesive bonding process was carried out. Adhesive joints made additive-free and formula 3 different commercial adhesives (Araldite 2015, Loctite 9466 PVA glue...

The aim of this study was to evaluate the sealing ability of materials filled in the orifice after root canal treatment. A total of 100 root canal-treated teeth were divided into six experimental groups: 1, Protect Liner F (PL); 2, Panavia F (PF); 3, DC core-Light cured (DCL); 4, DC core-Chemically cured (DCC); 5, Super-EBA (SE); 6, Ketac (KC). The materials were filled--to a depth of 4 mm--in ...

OBJECTIVES To evaluate the effect of photo-irradiation time to the adhesive on the regional bond strength of a dual-cure resin core material to root canal dentine using photo and dual-cure adhesives with self-etching primer. MATERIALS AND METHODS Post spaces were prepared in extracted premolars and then the root canal dentine was treated with one of the following bonding procedures: (1) Clear...

The purpose of this study was to investigate the effect of pH of different adhesive systems on the polymerization of a chemically cured composite resin (Adaptic--AD), by means of tensile bond strength testing. The adhesive systems tested were: ARM, Prime & Bond 2.1 (PB), Scotchbond Multi Purpose (SMP) and Single Bond (SB). Bond strength at the resin/adhesive system/resin interface was assessed....
