Comparación de la Penetración en los Túbulos Dentinales en el tercio apical de dos Cementos Resinosos, Vioseal® y AH-Plus® mediante Microscopio Electrónico de barrido(SEM): Un Estudio In Vitro

Abstract

Summary: Root canal sealants used to fill the space between the gutta-percha and the dentinal walls in endodontic therapy have been multiple and different, such as the highly studied AH-Plus® and other recent ones such as Vioseal®, the latter of which has little scientific evidence related to penetration into the dentinal tubules Objective: To compare the penetration into the dentinal tubules of two endodontic sealing cements, Vioseal® vs. AH-Plus® in the apical third mm4, through an in vitro study with electron microscopy sweeping. Method: Invitro experimental study in 30 human single-rooted teeth, they were randomly divided into 2 groups (n = 15) Vioseal® (n = 15) AH-Plus®, the teeth were prepared with Wave One Gold rotary files, they were filled with both cements according to the group, were stored at a temperature of 37° C, 100% humidity for 72 h, dried for 7 days, cut at millimeter 4, then observed in scanning electron microscopy (SEM 500x). Electronic photographs were taken of each root, then the most representative area was analyzed by measuring the depth of penetration in the dentin-cement sealant interface using the ImageJ software Analysis program. Statistical analysis plan: The observed penetration distance was analyzed analytically by measurements of central tendency, position and shape as graphically using a boxplot and to compare the penetration distance between the 2 cements, the Mann-Whitney u test or the T test for independent tests was used, in cases where the assumption of normality was met. is satisfied or not and the normality test is calculated using the shapiro wilk test. Results: the penetration distance (measured in um) is slightly greater in Vioseal® cement (viewed through the average or median (249.6) and for Ah-plus® (247.1). At the same time, less variability is observed in the distance for this cement (observed through the interquartile range or standard deviation for Vioseal® 67.67 and Ah plus® 93.69 and the same result is reached after analyzing the result of the graph (boxplot). Conclusion: Vioseal® and Ah plus®, presented penetration in 100% of the teeth evaluated, there is no statistically significant difference in the penetration distance between the 2 cements.
