“…However, it is available in powder and liquid forms. The restorative material obtained from the mixing of powder and liquid as per manufacturer's recommendation can polymerise itself or can be light activated to polymerise [ 16 ]. Considering the lesser chair side time available for restorations of pediatric patients, Cention N can be a better choice over composite.…”

“…On the one hand, RMGIC is a time-tested material with good clinical performance, and on the other hand, Cention N claims better anticariogenic and mechanical properties. Previous in vitro studies comparing Cention N to resin modified GIC evaluated parameters such as fluoride releasing ability, antibacterial property, flexural strength, and microleakage [ 5 , 16 – 19 ]. Our study compared the compressive strength, shear bond strength, and flexural strength of Cention N and RMGIC.…”

Background and Objectives. The child’s behaviour and cooperating ability are a crucial factor in deciding the restorative material for pediatric patients. Among the adhesive materials, glass ionomer cement has been the choice of restorative material while restoring primary teeth. However, due to poor physical properties such as wear resistance and water sorption, resin modified glass ionomer cements and composites that are light-cured adhesive restorative materials are preferred. Since the introduction of Cention N, as a self-cured smart alkasite material for restoration, some studies have demonstrated superior mechanical properties in comparison with conventional glass ionomers, modified glass ionomers, and composites. Predominantly, these studies evaluated properties such as microleakage, fluoride release, and marginal adaptation. We conducted this study to evaluate the compressive strength, flexural strength, and shear bond strength of Cention N in the primary teeth. Methods. 22 specimens prepared with Cention and RMGIC were embedded in primary teeth mounted in acrylic for analysing shear bond strength. Shear bond strength was analysed using a universal testing machine. The modes of failure in samples were observed under a stereomicroscope and scanning electron microscope. 22 customised samples of Cention N and RMGIC were prepared and categorised as group A and group B, respectively. The flexural and compressive strengths of these samples were evaluated using a universal testing machine. Results. The shear bond strength of RMGIC was higher than that of Cention N, whereas the compressive and flexural strengths of Cention N were significantly higher than those of RMGIC. The modes of failure were predominantly adhesive followed by mixed failures. Conclusion. The results of this study suggest that Cention N demonstrated superior mechanical properties compared with RMGIC and can therefore be recommended for restorations in primary posterior teeth. Cention N being a smart, esthetic, self-cured, or dual-cured material with better mechanical properties offers a wide range of applicability in primary teeth.

“…This is supported by an early study on curing kinetics, which shows that the same degree of conversion can be achieved regardless of the curing mechanism [ 27 ]. Additionally, a study on the mechanical properties of Cention N showed statistically similar FS [ 47 ] for light-cured and self-cured specimens, while another study even showed significantly higher FS for self-cured specimens [ 48 ]. In the latter two studies, the FS of Cention N (after storage at neutral pH) amounted to 83–86 MPa [ 47 ] and 62–83 MPa [ 48 ], which is much lower than the FS values reported for the newer encapsulated version (Cention), i.e., above 100 MPa [ 19 ], and the FS values of the latest version (Cention Forte) in the present study (108–140 MPa).…”

Although the compositional modifications made during the development of the alkasite have not been disclosed by the manufacturer, the modifications to improve flexural strength usually involve an increase in the amount of filler and/or modifications in particle size geometry, generally contributing to reduced mobility of the resin monomers at the micro-scale, ultimately diminishing the efficiency of curing [ 49 ].…”

This study aimed to evaluate the micro-mechanical and macro-mechanical properties of self-cured and light-cured alkasite and to investigate how accelerated degradation in acidic, alkaline, and ethanol solutions affects the macro-mechanical properties of self-cured and light-cured alkasite. The specimens of the alkasite material (Cention Forte, Ivoclar Vivadent) were prepared according to the following three curing modes: (1) light-cured immediately, (2) light-cured after a 5-min delay, and (3) self-cured. Microhardness was tested before and after immersion in absolute ethanol to indirectly determine crosslink density, while flexural strength and flexural modulus were measured using a three-point bending test after accelerated aging in the following solutions: (1) lactic acid solution (pH = 4.0), (2) NaOH solution (pH = 13.0), (3) phosphate-buffered saline solution (pH = 7.4), and (4) 75% ethanol solution. The data were statistically analyzed using a two-way ANOVA and Tukey post hoc test. The results showed that the microhardness, flexural strength, and flexural modulus were significantly lower in self-cured specimens compared to light-cured specimens. A 5-min delay between the extrusion of the material from the capsule and light curing had no significant effect on any of the measured properties. A significant effect of the accelerated aging solutions on macro-mechanical properties was observed, with ethanol and alkaline solutions having a particularly detrimental effect. In conclusion, light curing was preferable to self-curing, as it resulted in significantly better micro- and macro-mechanical properties, while a 5-min delay between mixing the capsule and light curing had no negative effects.
