Aims: To compare the apical sealing ability of TotalFill BC, AH Plus Jet, and GuttaFlow Bioseal sealers. Materials Methods: Thirty single rooted mandibular premolars were decoronated standardized at 15mm. The specimens chemo- mechanically prepared, randomized into three experimental groups (n =10) according to root canal sealer tested: Jet and, Bioseal. filled using cone technique. decalcified,...

introduction: this in vitro study aims to evaluate the coronal and apical sealing ability of gutta-percha (gp) root filling used with either mineral trioxide aggregate (mta), new endodontic cement (nec) or ah26 as filler/sealers. materials and methods: forty eight single-rooted extracted teeth were selected, decoronated and then instrumented. samples were randomly divided into three experimenta...

STATEMENT OF THE PROBLEM Alkaline pH can affect the physical and chemical properties and sealing ability of apical plug material. Calcium hydroxide is used as an intracanal medication to complete disinfection of root canals. It raises the pH of environment to alkaline value. PURPOSE The aim of this in vitro study was to evaluate and compare the effect of alkaline pH on the sealing ability of ...

Introduction This systematic review intended to compare the biocompatibility and sealing ability of mineral trioxide aggregate (MTA) and biodentine as root-end filling material. Materials and Methods A computerized literature search was performed on March 1, 2016, in MEDLINE, PubMed, and COCHRANE LIBRARY for data published from January 2011 to March 2016. Quality assessment of the selected st...

BACKGROUND The present study was aimed to evaluate and compare the apical sealing ability of two endodontic root-end filling materials namely, iRoot SP (ceramic based) and ProRoot MTA using the bacterial leakage system. MATERIAL AND METHODS A total of fifty recently extracted, single rooted teeth with a single straight canal were selected for the study. The teeth were chemo mechanically prepa...

introduction: the aim of this study was to compare the effect of post space preparation with gates glidden drills or hand files on the sealing ability of gutta-percha or resilon obturation materials. materials and methods: one-hundred and four single-rooted human teeth were instrumented and divided into four experimental groups (n=21 each) and two groups of positive and negative control (n=10)....

introduction: sealing ability of root-end filling materials is of great importance. it can be investigated by measuring microleakage. the purpose of this in vitro study was to evaluate microleakage of calcium enriched mixture (cem) cement in two different media including phosphate buffer solution (pbs) and distilled water. materials and methods: twenty single-rooted human teeth were selected. a...

Background: The apical seal is the single most important factor in determining the success of surgical endodontics, the aim of this study was to compare the sealing ability of Mineral Trioxide Aggregate in three different cavity designs. Materials and Methods: Thirty extracted human single-rooted teeth were divided into three groups of ten teeth per group, a retrograde cavity preparation was ca...

introduction: the aim of this study was to evaluate the effects of remnant root canal medicament, calcium hydroxide on the short and long term sealing ability of mineral trioxide aggregate (mta) apical barrier. materials & methods: fifty single-rooted teeth were prepared and apical resorptions were made using sulfuric acid. the teeth were allocated into two experimental groups and two control g...
