Bond Strength Evaluation of Two Resin Cements with Two Adhesives and Analysis of Mode of Failure
Author: Preethi Mohan
Publisher:

Languages : en
Pages : 160
Book Description
Cementing of indirect restorations with resin cements generally requires the pre-treatment of dentin with an adhesive. When dual-cured or chemical-cured resin cements are used with these single-step adhesives, incompatibility issues exist. This has resulted in manufacturers making chemical changes in their products. Kerr Dental markets a new resin cement, Nexus Third generation (NX3), which utilizes a proprietary redox system different from the second generation of composite luting agent (NX2). The aim of this study was to evaluate microtensile bond strength and mode of failure of NX3 and NX2 with two different adhesive systems (total-etch and self-etch) after 1 week and after 3 months of storage. Methods: Sixty-four non-carious teeth were sectioned to expose the dentin using a low-speed saw. Dentin surfaces were ground with 320-grit SiC paper. The adhesives Optibond Solo Plus (SOL), and Optibond All In One (AIO) were applied, and resin cements (NX2, NX3) were used to lute 4-mm composite discs to the treated dentin surfaces. Microtensile bond strength was determined at 1 week (IM) and after 3 months (3MON) of storage using a universal testing machine (MTS). All specimens were examined under the stereomicroscope to determine the mode of failure. Random specimens from each failure group were examined using scanning electron microscopy. Statistical Analysis: Comparisons between the treatment combinations for differences in microtensile bond strength were performed using Weibull-distribution survival analysis. Comparisons between the treatment combinations for differences in the failure mode were performed using Fisher's Exact tests. The group NX3 SOL IM (30.5 MPa) had significantly higher bond strength than NX3 SOL 3MON (13.4 MPa); NX3 AIO IM (11.3MPa); NX3 AIO 3MON (8.2 MPa; NX2 AIO 3MON (5.8 MPa); NX2 SOL IM (6.3 MPa), and NX2 SOL 3MON (3.2 MPa). The group NX2 AIO IM (19.3 MPa) was not significantly different from NX3 SOL IM. The group NX2 SOL 3MON and group NX2 SOL IM had a significantly higher percentage of teeth with mixed failure than all of the other groups. None of the other groups had significantly different failure mode. The group NX3 SOL IM had 90-percent beam survival beyond 17 MPa, and NX2 AIO IM had 50 percent of beams surviving beyond 17 MPa, a better performance. For all the other groups, more than 50 percent of beams failed below 17 MPa. Results show high evidence of degradation for all groups considered in this investigation. The use of these types of cement adhesive combinations in clinical situations should be used with this understanding.

'Objectives'. (1) To determine if the mode of polymerization of the bonding agent can influence the strength of the attachment of auto-cure resin luting cements to dentin. (2) To establish a standard method for a microtensile bond strength test at the Faculty of Dentistry. 'Methods'. Bovine dentin shear bond strengths were determined for two auto-cure resin cements using bonding agents with multiple modes of polymerization. Microtensile bond strength test apparatus was set-up and utilized with two groups from Part I of this study. 'Results'. Shear bond strength tests of 16 bonding agent/resin cement groups revealed significant differences between the groups (p

Comparison of Shear Bond Strength of Self Adhesive Resin Cements to Enamel and Dentin in the Dual Cure and Self Cure Modes

ISBN:
Category : Dental resins
Languages : en
Pages : 42
Book Description
All specimens were subjected to shear forces by a universal testing machine after 24hrs at a cross head speed of 1mm/min. Data were analyzed with Kruskal Wallis and Wilcoxon test to compare groups (¿=0.05). Results: Results showed SBS of RelyX Ultimate to be significantly greater than the 3 self-adhesive resin cements on both enamel and dentin in the dual cure mode as well as on enamel in the self-cure mode. However, Panavia SA and Speedcem were significantly greater than Rely X Ultimate in the self-cure mode on dentin. Dual cure activator improved the shear bond strength of RelyX Ultimate in the self-cure mode and no significant differences were found between the bond strengths of self-adhesive resin cements and RelyX Ultimate on dentin in the self-cure mode. Conclusions: For dentin, self-adhesive resin cements Panavia SA and Speedcem had better bond strength compared to RelyX Ultimate in the absence of light polymerization and therefore may be considered in cementing restorations such as zirconia and metal, where light transmission may be limited.
