AIM To evaluate the bond strength of one etch-and-rinse adhesive system and one resin-modified glass ionomer cement to sound and eroded enamel. MATERIALS AND METHODS Forty-eight bovine incisors were embedded in acrylic resin and ground to obtain flat buccal enamel surfaces. Half of the specimens were submitted to erosion challenge with pH-cycling model (3x/cola drink for 7 days) to induce ero...

This study evaluated the influence of the prolonged setting time of an ethanol-based adhesive system on the dentin bond strength and degree of conversion. Labial and lingual surfaces of fifteen human third molars were flattened until the dentin was exposed and randomly allocated to 3 groups (n = 10), according to the dwell time between the application of two consecutive layers of the adhesive s...

BACKGROUND Mineral trioxide aggregate (MTA) is a biomaterial that has been investigated for endodontic applications. With the increased use of MTA in pulp capping, pulpotomy, perforation repair, apexification and obturation, the material that would be placed over MTA as a final restoration is an important matter. As composite resins are one of the most widely used final restorative materials, t...

BACKGROUND This study aimed to investigate the microshear bond strength of universal bonding adhesives to leucite-reinforced glass-ceramic. METHODS Leucite-reinforced glass-ceramic blocks were polished and etched with 9.5% hydrofluoric acid for 1 min. The specimens were assigned to one of four groups based on their surface conditioning (n = 16): 1) NC: negative control with no further treatme...

AIM The aim of this in vitro study was to evaluate the influence of the Dental chair light on the bond strength of light cured composite resin. MATERIALS AND METHODS Sixty therapeutically extracted human premolar teeth were randomly allocated to two groups of 30 specimens each. In both groups light cured composite resin (Transbond XT) and MBT premolar metal brackets (3M Unitek) was used to bo...

The objective of this study was to evaluate the use of a two-step total etch and rinse adhesive, the correlation between the hyybrid layer thickness (HL) and bond strength (BS), and between resin tag length (RT) and bond strength in the same teeth, and also to evaluate the fracture patterns of the tested specimens. Ten human molars were used for the restorative procedure and then sectioned in t...

Purpose: The objective of this study was to evaluate the influence of the Grander technology on the shear bond strength of total-etch adhesive system Single Bond 2 to dentin. Materials and methods: Forty bovine incisors were used. They were sectioned and the buccal surfaces worn down with abrasive paper. Acid etching was performed, and the specimens were divided into two groups (n = 20): Group ...

BACKGROUND The aim of the study was to determine and compare the shear bond strength of brackets bonded with Adper Promt self-etching adhesive (3M ESPE), Xeno III self-etching adhesive (DENSPLY), Transbond plus self-etching adhesive (3M) with that of conversional bonding procedure, and to calculate the adhesive remnant index (ARI). MATERIALS AND METHODS Totally, 60 maxillary premolar teeth we...
