“…The results of the present study demonstrated that thermal cycling negatively influenced the quality of adhesive resistance, promoting the decrease in union values when the number of thermal cycles was increased. 14 38 41 42 43 44 Qualtrough et al . reported that there was a deterioration in marginal quality at the porcelain inlay/composite resin interface as a result of thermocycling.…”

PURPOSEThe purpose of this study was to find out the effect of immediate dentin sealing (IDS) on bond strength of ceramic restoration under various thermocycling periods with DBA (dentin bonding agent system).MATERIALS AND METHODSFifty freshly extracted human mandibular third molars were divided into 5 groups (1 control and 4 experimental groups) of 10 teeth. We removed enamel layer of sound teeth and embedded them which will proceed to be IDS, using All Bond II. A thermocycling was applied to experimental groups for 1, 2, 7, 14 days respectively and was not applied to control group. IPS Empress II for ceramic was acid-etched with ceramic etchant (9.5% HF) and silane was applied. Each ceramic disc was bonded to specimens with Duo-link, dual curable resin cement by means of light curing for 100 seconds. After the cementation procedures, shear bond strength measurement and SEM analysis of the fractured surface were done. The data were analyzed with a one-way ANOVA and Tukey multiple comparison test (α=.05).RESULTSThere were no statistically significant differences between 4 experimental groups and control group, however the mean value started to decrease in group 7d, and group 14d showed the lowest mean bond strength in all groups. Also, group 7d and 14d showed distinct exposed dentin and collapsed hybrid layer was observed in SEM analysis.CONCLUSIONIn the present study, it can be concluded that ceramic restorations like a laminate veneer restoration should be bonded using resin cement within one week after IDS procedure.

“…These limits appeared to be safe for usage in clinical settings, and oral tissues were found to tolerate them well. Osvaldo et al [ 19 ] immersed their research samples in water for 30 seconds at a time at temperatures ranging from 5°C to 55°C, with a total of 200-37,500 warm cycles. For the previous analysis, instances were subjected to 1,000 intensity cycles at 5-55 °C with a 20-second stay length.…”

BackgroundIn modern dentistry, fixed dental prostheses are often the preferred and the most complex treatment procedures. However, the success of these procedures depends to a great extent on the durability and consistency of the ongoing reconstruction. This paper aimed to compare the shear bond characteristics of conventional glass ionomer cement types, namely, Vivaglass luting cement and GC fuji 1 cement, after being subjected to two different dentin-cleaning techniques: the tungsten carbide bur and the prophy jet. This would help determine whether the castings that have been cleaned and recemented are just as tenacious as when they were initially placed. MethodologyA total of 60 human teeth extracted due to periodontal disease were collected for this study. The teeth were cleaned and stored in a thymol arrangement after carefully removing any leftover fragile tissue. They were randomly grouped as follows: luted with Vivaglass cement (N = 30) in group A and GC fuji 1 cement (N = 30) in group B. Each group's debonded surfaces were arbitrarily split into three subgroups, with each containing 10 samples. This was done to comply with dentin-cleaning techniques for recementation. ResultsThe intergroup bond strengths calculated were compared among the subgroups. The mean strength for subgroup IA was 2.78 ± 0.24 MPa, subgroup IB was 2.60 ± 0.30 MPa, subgroup IIA was 4.39 ± 0.19 MPa, subgroup IIB was 3.80 ± 0.23 MPa, subgroup III A was 4.52 ± 0.22 MPa, and subgroup IIIB was 3.63 ± 0.17 MPa. An analysis of variance test showed there was a significant difference between the subgroups (F = 117.60; P = 0.001). The results revealed that there was a significant difference between the subgroups. Shear bond strength testing was performed using common testing equipment. The results indicated that there was not any significant difference between the mean increases in the shear bond strength of the two luting cement types. However, the GC fuji 1 cement showed greater initial shear bond strength than the Vivaglass cement. Additionally, when the tungsten carbide bur was used as a cleaning technique before recementing, it showed greater shear bond strength compared to the prophy jet. ConclusionsThe initial shear bond strength of GC fuji 1 (Group B) luting cement was slightly higher than that of Vivaglass (Group A), and the bond strength achieved after recementation with GC fuji 1 and surface cleaning with the carbide bur was the highest among the other three groups.

“…This led to the creation of two groups of samples with three assemblies of metallic blocks cemented to resin blocks, which were attached by cyanoacrylate adhesive (Super-Bonder, henkel ltda., Itapevi, SP, Brazil) to a cylindrical acrylic base connected to a machine especially designed by Andreatta Filho et al (2003) 1 for sectioning with carborundum discs measuring 0.15mm in thickness and 22mm in diameter, to the nearest 0.1mm.…”

“…The bond of resin compounds to metallic alloys has been improved during the past decades and several techniques have been developed in an attempt to achieve a stable bond. Sandblasting the metallic alloys with aluminum oxide is commonly employed for surface cleaning and a proper retentive topography, with a consequent increase in the adhesive bond 1,12,17 .…”

The aim of this study was to evaluate the effect of thermocycling on the bond strength between resin cement and titanium alloy with silica coating. Six titanium alloy blocks (Rematitan, Dentaurum) were cast with dimensions of 5x6x6mm. One of the faces measuring 5x6mm of each titanium alloy block was etched with the CoJet System (3M ESPE – silica coating) and luted with Panavia F (Kuraray) to another identical block made from composite resin Z100 (3M ESPE) under a constant 750g load. The six samples formed by titanium alloy, cement and composite resin were split up in a mechanical lathe and 30 samples measuring 10x1x1mm were achieved, with an adhesive surface area of 1mm2 ± 0.2mm2. The samples were divided into 2 groups (n=15): G1 (group 1) – stored for 1 day in distilled water at 37°C; G2 (group 2) – thermocycling for a total of 2,700 cycles (5°C – 55°C, dwell time: 30s). The microtensile test was accomplished in a universal testing machine (EMIC) at a crosshead speed of 1.0 mm/min. Means and standard deviations of bond strengths (MPa) were 44.50±8.41 for G1 and 38.03±7.63 for G2. Data were analyzed using the unpaired Student t test (p<0.05). There was a statistically significant difference between groups G1 and G2 (t=2.206; df=28; p=0.036). The bond strength values between the titanium alloy surface and the resin cement decreased after thermocycling.
