“…Fluid transport is based on the penetration of fluid in through-and-through pores within or between the filling material and the dentinal wall in a root canal under light pressure [ 12 ]. Capillary action; entrapped air/liquid; and the fluid characteristics such as its pH, its molecular size, and its surface tension may affect the penetration of the fluid [ 11 ].…”

“…The fluid transport method has been widely used for measuring the sealing efficacy of root fillings non-destructively and quantitatively [ 7 , 11 , 12 ]. The fluid transport model has been commonly operated with distilled water as a testing fluid [ 12 , 13 ]. The introduction of a wetting fluid with a lower surface tension as testing fluid was a recent modification of the fluid transport method, which significantly improved its sensitivity [ 11 ].…”

ObjectivesThe aim of the present study was to compare the sealing efficacy of root fillings made by a single-cone technique with three different sealers and a cold lateral compaction technique with an epoxy sealer.Materials and methodsEighty extracted single-rooted human teeth were assigned to four experimental groups: group 1, single-cone and epoxy sealer; group 2, single-cone and calcium silicate-based sealer; group 3, single-cone and methacrylate resin-based sealer; and group 4, cold lateral compaction and epoxy sealer. Twenty extra teeth served as negative and positive controls. After preparation of a coronal post space, the sealing efficacy of the root fillings was assessed on a fluid transport setup. The results were analyzed using Kruskal-Wallis and Mann-Whitney U test.ResultsNo fluid transport was detected for the negative controls whereas all the positive controls showed rapid fluid transport. No significant difference was detected between groups 1, 3, and 4 whereas group 2 demonstrated significantly more fluid transport than all the other experimental groups.ConclusionsRoot fillings made by a single-cone technique with the epoxy or methacrylate-based sealers were as effective after post space preparation as those made by a cold lateral technique with the epoxy sealer in sealing the root canal.Clinical RelevanceSpecific root canal sealers in combination with single-cone technique represent a noteworthy alternative to the use of cold lateral compaction technique when a post space is required. The use of effective endodontic procedures with simplified technical implementation may positively affect endodontic outcome.

“…The specimens Long-term sealing cements Mestres et al were divided randomly into eight groups (n = 10), because the four cement types were applied either as root canal sealers together with gutta-percha or as filling materials with no gutta-percha. The cements were introduced into the root using a lentulo spiral (Vizgirda et al 2004, Monticelli et al 2010. When the cements were applied as sealers, a size 30 master gutta-percha -point was lightly coated with the cement and placed into the canal to working length.…”
