“…11,12 Methylene blue was used as the dye as it is readily detectable under visible light, has ability to diffuse easily, not absorbable by dentinal matrix apatite crystals 13 and the most coronal extent of the leakage is easily detectable. 14 It also penetrates voids better than isotopes 15 and has a low molecular weight thereby penetrating more deeply along root canal fillings. 16 This study was done to assess the sealing property of AH 26, Sealapex, Endoflas FS and AH Plus by the centrifuging dye penetration method.…”

Aim The aim of this in vitro study was to evaluate the apical seal obtained with four root canal sealers AH 26, Sealapex, Endoflas FS and AH Plus, with lateral condensation. Materials and methods Sixty root canals were prepared using the step-back technique. The specimens were divided into four experimental groups of 12 teeth and two control groups of 12 teeth. The experimental groups were obturated by laterally condensed gutta-percha with one of the tested sealers and control groups were obturated without any sealer. Methylene blue dye penetration with centrifuging method was used to evaluate the apical sealing ability. The quantitative apical leakage of each specimen was measured after 2 weeks. Results The results showed no significant differences between all groups except between AH Plus and Endoflas FS (<0.05). AH Plus showed significantly less leakage than Endoflas FS. Conclusion AH Plus showed the least leakage compared to AH 26, Sealapex and Endoflas FS. How to cite this article Joseph R, Singh S.

“…Occlusal loads acting on the tooth were reported to increase periapical hydrostatic pressure and this in turn affected the seal between the filling material and the root canal wall (Dobo-Nagy et al 2003). A direct relationship between the magnitude of occlusal pressure and the volume of periapical leakage was also described (Esber et al 1998). Although many earlier studies evaluated the effects of orthograde fluid leakage and apical seal in root-filled teeth, only a few investigations have been conducted to examine the response in the periapical region to biting forces and the role of cyclic biting forces on periapical fluid dynamics.…”

“…The different pressures applied may result in different volumes of leakage. A significant increase in the leakage of root‐canal fillings has been observed after repeated occlusal loading (Esber et al . 1998).…”

Direct proportionality was found between the coronal loading and the apical hydrostatic pressure. The DeltaP/DeltaF ratio determined in this study makes it easier to estimate the apical hydrostatic pressure values during occlusal loading of single-rooted teeth. In this study, the apical pressure generated under occlusal loading was the same magnitude as that estimated with the finite element method.
