Comparative Evaluation for Microleakage between Hydrophilic Resin Based Sealant and Sealant Containing S-PRG Filler With and Without Moisture Contamination: An In Vitro Study.
Abstract: Objectives: The aims of this in-vitro study were to compare two types of sealant materials for microleakage and to evaluate the effects of saliva contamination on the microleakage of both types of sealants. Methods: Forty-eight sound human third molars were randomly distributed into four groups: (1) UltraSeal XT hydro in dry condition; (2) UltraSeal XT hydro in contaminated condition; ... read more(3) BeautiSealant in dry condition; (4) BeautiSealant in contaminated condition. All teeth were subjected to thermocycling procedure followed by staining with 1% methylene blue dye. All teeth were embedded into resin then sectioned in buccolingual direction into three sections. The depth of dye penetration was evaluated using a stereomicroscope and was recorded according to the dye penetration score system (0-3). Data were analyzed with the Kruskal-Wallis and Mann-Whitney U tests. Results: UltraSeal XT hydro showed significantly lower microleakage than BeautiSealant in both dry and contaminated conditions (p<0.001, p=0.001, respectively). There was no statistically significant difference in microleakage between UltraSeal XT hydro in dry and contaminated conditions. Also there was no statistically significant difference in microleakage between BeautiSealant in dry and contaminated conditions. Conclusions: With the consideration to the limitations of an in-vitro study, we can conclude that UltraSeal XT hydro, in both dry and contaminated conditions, had significantly lower microleakage than BeautiSealant. There was not statistically significant evidence of a difference in microleakage between UltraSeal XT hydro in dry and contaminated conditions.
