“…The present study showed statistical differences between the cement tested in both light sources, but none had DC% lower than acceptable values in other studies [21,22]. Besides color stability, it should be highlighted that the longevity of the cemented ceramic restorations also depends on the correct cementation technique, with proper control of humidity using dental isolation [23,24], control of gingival bleeding during cementation [25], and proper removal of resin cements excesses [26]. 3.…”

Objective: To evaluate the color stability and degree of conversion of light-cured resin cement with different activator-initiator systems using LED lights with different wavelengths (polywave x monowave). Materials and Methods: Sixteen resin cement samples were made using a circular silicone matrix (7 mm diameter, 0.5 mm thickness) for each of the following tested materials: Variolink Esthetic LC (Ivoclar, color Light+); RelyX Veneer (3M ESPE, color A1); Filtek Z350XT flow resin (3M ESPE, color A1); Allcem Veneer APS (FGM, color A1); NX3 Light cure (Kerr, color A1). Half of the samples were photocured with a monowave LED light (Elipar Deep Cure), and the other half with a polywave LED light (Valo Grand). The initial color of each cement was measured using a high translucency ceramic sample simulating ceramic venner. Color measurements were performed with a reflectance colorimetric spectrophotometer and the data was collected according to the CIE L* a* b* system in two steps. The degree of conversion was measured using an infrared spectrometer by Fourier transform (FTIR / ATR) using the absorbance method. Statistical analysis was performed using ANOVA repeated measures and Tukey’s post hoc tests (p <0.05). Results: For the color analysis, there were no significant differences between the cement related to time versus light curing (p = 0.084) and also related to time versus cement versus light curing (p = 0.142). Among the factors, there was only a statistically significant difference for the type of cement (p <0.01). In contrast, for the photocuring device (p = 0.504) and the interaction between them (p = 0.738), there was no significant difference. For the degree of conversion analysis (DC), it showed a statistically significant difference for both factors, resin cements (p <0.01) and light curing units (p <0.01). Conclusion: The color stability of RelyX cement is low compared to other cements, while Variolink cement presented the best degree of the conversion value.

“…The cleansing efficacy of some of these cleansing methods for the bond strength of some cements has been previously investigated [ 4 – 6 ]. However, the available literature on this topic is inconclusive [ 7 , 8 ]. Therefore, this study aimed to assess and compare the effect of various mechanical and chemical cleansing protocols on the bond strength of an etch-and-rinse adhesive to dentin contaminated with aluminum chloride hemostatic agent.…”

Objectives: Inadequate removal of the hemostatic agent can adversely affect the bond strength of restorations to the tooth structure. This study aimed to assess the effect of different cleansing protocols on the shear bond strength (SBS) of an etch-and-rinse adhesive to dentin contaminated with aluminum chloride hemostatic agent. Materials and Methods: In this experimental study, the mid-coronal dentin of 96 premolars was exposed. They were contaminated with a hemostatic agent (ViscoStat Clear) and then randomly divided into 7 groups (n=12). One group served as the control. The groups underwent various cleaning methods as follows: water spray, aluminum oxide particles (27µ diameter), a slurry of pumice with water, GC dentin conditioner (GCDC), sodium hypochlorite 2% (SHC), and chlorhexidine 2% (CHX). Composite cylinders were then fabricated and bonded to the surfaces using Scotchbond Multi-Purpose etch-and-rinse bonding agent. After thermocycling (10,000 cycles), the SBS was measured using a universal testing machine. Data were analyzed using one-way analysis of variance (ANOVA) and Tukey HSD (honestly significant difference) test, and the significance level was set at 0.05. Results: The SBS of the groups was significantly different (P=0.036). The SBS was the highest in the CHX and SHC groups, and the lowest SBS was related to the control group and GCDC groups. The difference between other groups was not significant (P=0.996). Conclusion: CHX and SHC yielded the highest bond strength among the tested modalities for cleansing the ViscoStat Clear from the tooth surface.
