“… 38 Fuji II LC specimens were found to have bond strengths similar to those of Cention N specimens with an adhesive and Tetric N Ceram specimens, but had microleakage comparable to that of Cention N specimens without an adhesive. Although no direct correlation between adhesive strength and microleakage has yet been reported, 39 the high microleakage observed for Fuji II LC could be attributed to the significant degradation of HEMA combined with its hydrophilicity. 40 …”

Objective: In this study, a comparative evaluation of the physicochemical properties of Cention N and other direct restorative materials was performed. Three restorative materials—a resin-modified glass ionomer (Fuji II LC), an alkasite-based resinous material (Cention N), and a resin composite (Tetric N Ceram)—were characterized in terms of degree of conversion, Knoop hardness number (KHN) ratio, flexural strength, elastic modulus, water sorption, water solubility, microshear bond strength to dentin, immediate microleakage, and radiopacity. Methodology: The microshear bond strength to dentin and microleakage of Cention N were evaluated with and without the application of an adhesive system (Tetric N Bond Universal). A one-way ANOVA test was used to analyze the data in terms of degree of conversion, KHN ratio, water sorption, water solubility, microshear bond strength to dentin, and radiopacity. A two-way ANOVA test (carried out considering the material type and ethanol aging as factors) was used to analyze the data in terms of flexural strength and elastic modulus. The Kruskal–Wallis test was used to statistically analyze the data on microleakage. A significance level of α=0.05 was used for all tests. Results: Fuji II LC was found to have the highest degree of conversion, water sorption, and microleakage, as well as the lowest flexural strength. Cention N had the highest solubility; when used with an adhesive system, it achieved bond strength and microleakage similar to those of the Tetric N Ceram composite. Tetric N Ceram had the highest degree of conversion, KHN ratio, and radiopacity. Conclusion: The properties of Cention N validate its efficacy as an alternative direct restorative material when used in conjunction with an adhesive system.

Objetivo: evaluar in vitro la microfiltración marginal en restauraciones con resina compuesta clase II en dientes posteriores. Método: Se realizó un estudio de diseño cuasiexperimental de corte longitudinal, la muestra estuvo conformada por 40 dientes posteriores superiores e inferiores (premolares y molares) sanos, estos fueron extraídos por indicaciones ortodónticas o periodónticas y se han conservado en agua destilada por 48 horas; se excluyeron aquellos dientes que tenían restauraciones oclusales o alguna alteración de forma o estructura. Los dientes fueron distribuidos aleatoriamente en 02 grupos experimentales. El grupo experimental 1 (GE1) recibió la restauración con resina compuesta clase II con base ionomérica y el grupo experimental 2 (GE2) recibió la restauración con resina compuesta clase II sin base ionomérica. Resultados: al comparar el grado de microfiltración marginal entre el GE1 y GE2 a las 48 horas, 15 días, 30 días y 45 días con un nivel de confianza de 95% existe diferencia estadísticamente significativa (p < 0,05), es decir que, existe un mayor grado de microfiltración marginal en restauraciones con resina compuesta clase II sin base ionomérica. Conclusión: Las restauraciones con resina compuesta clase II en dientes posteriores que no tuvieron una base ionomérica tienen mayor grado de microfiltración marginal.
