The use of calcium hydroxide has widely spread in recent decades due to its easy availability and use, its low cost, and the fact that it is often used in cases of apexification, showing great success in inducing an apical hard tissue barrier in the immature open apex. Its effectiveness has been demonstrated by clinical studies and long-term success rates ranging between 74% and 100%. The apexi...

AIM To compare the long-term apical sealing ability of gutta-percha/AH Plus and Resilon/Epiphany. METHODOLOGY The root canals of 90 single-rooted human mandibular premolars with single narrow root canals were prepared with ProFile 0.4 taper instruments to apical size 40. After each instrument, the canals were irrigated with 1% sodium hypochlorite. Subsequently, the teeth were randomly divided...

The aim of this study was to evaluate two root canal filling techniques used in teeth that had their apical foramen disrupted and compare the apical infiltration with an ideal clinical situation. Twenty-seven freshly extracted single-rooted teeth were selected and radiographed to confirm the existence of a single and straight root canal. The crowns were removed at a mean distance of 11 mm from ...

purpose: the aim of this study was to compare the effects of a) a flame heated endo plugger, b) gatesglidden drills and c) gpx drills on the apical seal for the purpose of post space preparation. materials & methods: the crowns of sixty six extracted maxillary central teeth were removed from cej by a diamond disc and the root canals were prepared and obturated with guttapercha and sealer (ah26)...

iran has limited water resources that require preservation and reducing water loss from reservoirs, especially in arid and semi arid regions. there are a number of methods available for to control water loss from reservoirs and canals. concrete linings in water reservoirs and ponds are durable, but their efficiency is limited. geomembrane sheets are another method of controlling leakage from wa...

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 ob...

The purpose of this study was to evaluate the influence of coronal leakage on the healing of dogs' periapical tissues after root canal filling, post space preparation and protection or not with a temporary sealer plug. Forty root canals of dogs' teeth were instrumented and filled by the lateral condensation technique with gutta-percha points and Endomethasone or CRCS sealers. After post space p...

background. maximum sealing ability or adhesion of endodontic sealers can be achieved after an effective removal of smear layer. endodontic irrigants assist in adequate removal of smear layer and thus improve the retention mechanism. the aim of this study was to evaluate the effect of two different root canal irrigating solutions (5.25% naocl followed by 17% edta and qmix) on the apical sealing...
