OBJECTIVES To evaluate the effect of application time on the resin-dentin bond strength (µTBS) and etching pattern of adhesive systems applied on sclerotic dentine. MATERIAL AND METHODS A total of forty-two bovine incisors had their roots removed. The 1-step self-etch GO (SDI), the 2-step self-etch Adper SE Bond (3MESPE) and the 35% phosphoric acid (3MESPE) from the 2-step etch-and-rinse Adpe...

ABSTRACT Objective To evaluate the effect of 0.2% chlorhexidine digluconate (CHX) as a pretreatment two types adhesive systems on color stability composite resin restorations. Methods Forty bovine teeth were prepared (6x6x2mm) and randomly divided into 4 groups (n=10): SB - total etch (Single Bond 2, 3M ESPE); + CHX dentin with (30 seconds) followed by application; Adh self-etch (AdheSE, Ivocla...

The oxide etch rate of plasma etch tools is estimated from plasma impedance monitoring data. Linear statistical modelling and stepwise regression are used to generate predictions of the mean and range oxide etch rate. The relationship of the mean etch rate to yield is explored for one processing step. Potentials for advanced process control of the etch tools are presented.

objective: a clinical challenge of using zirconia frameworks is to achieve adequate bond with different substrates. this study aimed to evaluate the effect of bioglass and silica coating of zirconia substrates on microshear bond strength of resin cement to tetragonal zirconia. methods: this laboratory experimental study was conducted on zirconia discs. a total of 120 ytzp zirconia (zirkonzahn) ...

OBJECTIVES The aim was to determine the effect of blood contamination and haemostatic agent application on the shear bond strength (SBS) of different adhesives to dentin. MATERIALS AND METHODS Seventy-two extracted human molars were used in this study. Teeth were mounted acrylic in moulds. Mesial and distal surfaces were removed to obtain flat dentin surfaces (n=144) and grinded with a 600 gr...

OBJECTIVES Several adhesive systems are available for cementation of fibre posts into the root canal. The aim of the present study was to investigate the push-out bond strengths of quartz fibre posts to root dentin with the use of different total-etch and self-adhesive resin cements. STUDY DESIGN Ninety single-rooted human premolars were endodontically treated and standardized post-spaces wer...

background: the aim of this study was to determine the microtensile bond strength (μtbs) of ceramic and composite computer aided design‑computer aided manufacturing (cad‑cam) blocks bonded to dentin using different adhesive strategies. materials and methods: in this in vitro study, 30 crowns of sound freshly extracted human molars were sectioned horizontally 3 mm above the cementoenamel junctio...
