This study evaluated the shear-bond strength of a resin-modified glass ionomer (RMGI) restorative material to a new silorane-based composite and a methacrylate-based composite in a sandwich technique with various combinations of surface treatments and bonding agents. Two composites, 2 bonding agents and 4 surface preparations were used to create 16 groups with 10 specimens each. After 24 hours ...

PURPOSE The aim of this study was to determine differences in shear bond strength to human dentin using immediate dentin sealing (IDS) technique compared to delayed dentin sealing (DDS). MATERIALS AND METHODS Forty extracted human molars were divided into 4 groups with 10 teeth each. The control group was light-cured after application of dentin bonding agent (Excite® DSC) and cemented with Va...

The aim of this study was to enhance the bond strength of one-step bonding agents to dentin. In particular, the focus was on using Catabrush the applicator system of AQ Bond Plus. Catabrush was supplemented with N-phenylglycine and aromatic sulfinate as polymerization accelerators, as N-phenylglycine was reportedly beneficial in improving the bond strength to dentin. The results indicated that ...

All ceramic restorations benefit from resin cement bonding to the tooth. No currently available luting agent is ideal for all situations. The comparison of the bonding ability of different luting cements to ceramic and dentin is thus deemed necessary. The purpose of this study was to evaluate the shear bond strength of different luting cements to both ceramic and dentin and then to evaluate the...

The title compound, C(17)H(24)NO(5)S(+)·C(18)H(13)O(8) (-), is the key inter-mediate during the preparation of lesatropane [systematic name (1R,3S,5R,6S)-6-acetoxy-3-(4-methylphenylsulfonyloxy)tropane], a potential anti-glaucoma agent. The tertiary N atom of the tropane ring is involved in inter-molecular N-H⋯O hydrogen bonding, and the carboxylate groups are involved in inter-molecular O-H⋯O h...

  Abstract Introduction: One-bottle light-cured adhesives systems have variable pH. In addition to ease of use, universal adhesives can be used in various restorations and different substrates. Due to the lack of studies, the purpose of this study was to compare the enamel and dentin micro-leakage of self-cure and light cure composite restorations using a universal bonding system. Materials...

objective: the objective of this study was to compare the tensile bond strength of metal brackets bonding to glazed ceramic surfaces using three various surface treatments. materials and methods: forty two glazed ceramic disks were assigned to three groups. in the first and second groups the specimens were etched with 9.5% hydrofluoric acid (hfa). subsequently in first group, ceramic primer and...

The effect of bleaching on fracture toughness (Kic) of existing composite-dentin interfaces was assessed using the notchless triangular prism (NTP) specimen fracture toughness test. Human molars and premolars (<6 months old) were wet ground on 600 SiC to obtain 4x4x4x4mm triangular prisms with buccal or lingual exposed for bonding. Buccal or lingual dentin surfaces, ground on 600 grit sandpaper...

This study aimed to compare the push-out bond strength of a bulk-fill and conventional composite resin root dentin primary anterior teeth using 7th-generation bonding agent. in vitro evaluated 24 randomly divided into two groups: Filtek P60 resins. Single Bond Universal adhesive was used for bonding. After filling coronal part canal with resin, were mounted acrylic sliced obtain 1-mm-thick sect...
