Evaluación de la microfiltración marginal que presenta el cention-n fotocurado y autocurado en comparación con la amalgama por análisis de estereomicroscopía: estudio in vitro

Abstract

ntroduction: Amalgam is one of the most used materials in dentistry due to its great resistance to compression, its good marginal adaptability, but distinguished by its aesthetic characteristics and mercury composition. Ivoclar Vivadent developed a material (Cention N) which it presents as a replacement for amalgam in its restorative properties and which is also sufficiently aesthetic. The foregoing motivates us to compare the marginal microfiltration and wonder if this material (Cention N), compared to amalgam, presents a greater or lesser marginal microfiltration that could alter the prognosis of a class II restoration in dentistry through an in-vitro study. . Materials and methods: 21 natural upper and lower posterior teeth were used, a Black class II cavity was made and they were distributed in 3 groups of 7 samples, (Amalgam, Cention N light-cured, Cention N self-cured), then they went through a process thermocycling. Results: In the occlusal microfiltration depth analysis by filling material of the amalgam group, a mean of (1903.375 µm) was obtained followed by the Cention N group of Self-curing (2658.917 µm) without statistically significant difference ( P = 0.175). While, for the measurement of gingival microfiltration depth, the one that presented the least microfiltration was the Cention N Light-cured group (2582.929 µm), followed by the amalgam group (3622.287 µm); this group did present statistically significant differences (P = 0.035). Conclusions: 100% of the samples restored with amalgam and Cention N presented marginal microfiltration. In the studies according to the depth of the microfiltration, it is evidenced that the amalgam presented less marginal microfiltration than the Cention N, it was also evidenced that the Photocured Cention N, presented less marginal microfiltration than the Self-cured Cention N.
