“…Theoretically these tests could also provide a basis for comparison of sealers and techniques 6 bu t , unfortunately, there has been no standardization of testing methods and most studies have had i n a d e q u ate controls to test the experi m e n t a l design. 4,[7][8][9] The results of Oliver's study 4 and other recent work 5,[10][11][12] suggest that apical leakage may not be the obturated with gutta percha and Roth's 801 Sealer § (a zinc oxide-eugenol based sealer). This in vitro study appeared to have been performed on dry tooth roots which may have affected the bond between Ketac-Endo and the root dentine so it is impossible to relate these findings to normal clinical situations.…”

“…Several other studies have used in vitro bacterial and dye leakage tests to investigate the concept of coronal microleakage of bacteria into obturated root canals and it is now widely accepted by endodontists that coronal leakage is far more likely to be the major determinant of clinical success or failure. [10][11][12] Therefore, it now appears that tests concerning the sealing ability of root canal sealers and techniques should be designed to test both the apical and the coronal seals.…”

The purpose of this in vitro study was to compare both apical and coronal dye penetration when Ketac-Endo and AH-26 sealers were used with laterally condensed gutta percha. Crowns were removed from 28 teeth and the root canals were biomechanically prepared. The teeth were divided into two groups of 12 teeth each and a control g r o u p of 4 teeth. Root canals in the two experimental groups were filled with laterally condensed gutta percha and either Ketac-Endo or AH-26 sealer. The Ketac-Endo group had the coronal 3 mm of gutta percha and sealer removed and the resultant cavity was filled with Ketac-Endo alone. After the sealers had set, the root surfaces were coated with nail varnish except at the apex and at the coronal end. Positive controls had no root fillings and were coated with nail varnish in the same manner while the negative controls were sealed apically and coronally with Cavit prior to sealing the entire external root surface with nail varnish. Specimens were placed in 2% methylene blue dye in a vacuum of 660 mm of mercury for five minutes and then left immersed for a further two days. The roots were vertically sectioned to determine the following mean levels of dye penetration: Ketac-Endo, 1.08 mm apically and 6.29 mm coronally; AH-26, 0.75 mm apically and 6.67 mm coronally. Positive controls had total leakage and negative controls had no leakage. This study demonstrated that the apical and coronal seals obtained with Ketac-Endo and AH-26 were not significantly different although the apical seal obtained with each material was significantly better than the corresponding coronal seal.

“…23 Compared with zinc oxide-eugenol sealers, methacrylate based resin sealers were found to be more effective in sealing. 24 Using a fluid-transport method, Tunga and Bodrumlu concluded that Epiphany and Resilon leaked significantly less than gutta-percha and AH-26. 25 In bacterial leakage tests Epiphany and Resilon were superior to gutta percha and various other sealers.…”

The main aim of root canal therapy is the removal of microbial contaminants in conjunction with the total closure of the root canal system. Root canal sealers along with solid core material plays a major role in achieving the three dimensional sealing of the root canal system. These sealers are binding agents which are used to adapt the rigid gutta-percha to canal walls and to fill up the voids, accessory canals and irregularities within the canal. Root canal sealers, although used only as adjunctive materials in the obturation of root canals, have been shown to influence the outcome of endodontic treatment. A perfect combination of sealing ability and biocompatibility is what an ideal root canal sealer should possess. This article discusses the current concepts in the usage of different sealers in endodontic therapy and their comparison in order to draw some clinical inferences.

Restoratif diş tedavisinin en büyük sorunlarından biri, endodontik tedavisi yapılmış, kuronal bölgesinde üst yapı oluşturmak için yeterli sağlam diş dokusu bulundurmayan dişlerin restorasyonudur.…”

and Rely X U200 (3M ESPE, Neuss, Germany). The measurement of microleakage was performed at 2nd, 4th, 6th and 8th minutes. The data was analyzed by ANOVA and Tukey tests (p<0.05). Results: The best results were obtained in Rely X U200 and Panavia SA Cement groups, while the most leakage was seen in G-Cem Automix and Smart Cem 2 groups (p<0,05). There was statistically significant difference between Rely X U200 and Panavia SA Cement groups compared to the control group (p<0,05). The control group was found to have statistically less microleakage than G-Cem Automix and Smart Cem 2 groups (p<0,05). Conclusion:From the point of microleakage, some self adhesive resin cements used for fiber post cementation were found to be more reliable than the control group material.
