“…The early moisture contamination could decreases mechanical properties of GICs favoring surface erosion and abrasion. In the present study, GIC specimens were protected from the influence of water by a thin colorless glaze preventing water contamination on the initial phase of the setting to endure 24h up to 2 weeks 24 .…”

Aims:To evaluate the effect of the chlorhexidine (CHX) incorporation and the storage time on the mechanical properties of glass ionomer cements (GICs). Methods: The following GICs were evaluated: Ketac Molar Easymix (KM), Vidrion R (VR) and Vitromolar (VM), containing or not CHX. GIC liquid was modified by adding 1.25 % CHX digluconate and then manipulated with the power and placed into the stainless steel cylindrical or bar-shaped molds. GICs specimens were stored into water for 1, 7 and 28 days. After these periods, specimens were submitted to flexural, diametral tensile and compressive strength tests, according to ISO standards. Data from mechanical tests were statistically analyzed using 2-way ANOVA and Tukey tests. Results: Overall, the storage time did not influence any of the mechanical properties of the GICs tested. In contrast, the inclusion of CHX reduced significantly these properties for all GICs tested. KM presented the highest values of compressive strength for all storage times. KM + 1.25% CHX had lower compressive strength results than KM, however, it showed similar results when compared to another GICs without CHX. Conclusions: The presence of chlorhexidine, independent of the storage time, interfered on the mechanical characteristics of GIC.

“…Previously, studies used water, acids, and other solvents to simulate the contaminating environment of mouth to test behavior of luting agents. [4,5] For in vitro tests, the chemical structure of the solutions should be used as it stimulates the complexity of the oral environment. [6] In this study, to maintain standardization of the test conditions, samples were kept in incubator at 37°C during immersion period and to maintain pH of storage media, it was changed every week.…”

Background:The clinical success and durability of luting cements are determined by structural integrity and dimensional stability. Sorption and solubility resin luting cements in food-simulating solutions has not been studied sufficiently. Aims and Objectives:To compare the sorption, solubility, and flexural strength of resin luting cements in artificial saliva, ethanol:water (1:1) and distilled water at 37°C. Materials and Methods: Four commercially available resin cements were selected. Disk-and rectangular-shaped samples will be prepared according to ISO standard-4049. Out of 160 specimens, 120 disc-shaped specimens will be subjected to sorption and solubility analysis. 40 rectangular-shaped specimens will be subjected for flexural strength analysis. Results: The result of the study clearly depicted that highest water sorption was observed for GC Fuji Cem in distilled water and artificial saliva media. For Composite Ionomer highest sorption was observed in ethanol:water medium. Panavia F showed least sorption in all three media. GC Fuji Cem exhibited more solubility in artificial saliva and ethanol:water (1:1) media, Composite Ionomer showed more solubility in distilled water medium. Secure luting agent showed least solubility in all three media. Highest flexural strength was observed by Panavia F and least by Tokeyoma Ionomer. Conclusion: Within the limitation of this study resin luting (Panavia F and Secure) agents showed least sorption, solubility, and highest flexural strength than compared to resin reinforced glass ionomer cement (GC Fuji Cem and Tokeyoma Ionomer).

“…But it is greatly affected by moisture and blood during the initial setting time, resulting in increased solubility and decreased bond strength . [37][38] Later MTA was developed as a new root end filling material. The sealing ability, marginal adaptation of MTA was investigated .Good results were obtained with MTA when ranked with other materials .…”
