introduction: this study compared the apical sealing ability of a bioceramic based root canal repair filling material (iroot fs) with mineral trioxide aggregate (mta). methods and materials: forty single-canal teeth were prepared and randomly divided into two experimental groups ( n =18) and two control groups ( n =2). teeth in experimental groups were retrofilled with either mta or iroot fs. a...

introduction: the purpose of this study was to evaluate the efficacy of three methods in removal of resilon/new epiphany self-etch (se) soft resin endodontic obturation system. materials and methods: thirty extracted single rooted human teeth were prepared for endodontic treatment and obturated with resilon/epiphany se. the roots were randomly divided into three groups; group 1 roots were retre...

Introduction: Statement of the Problem: Cleaning and shaping are regarded as the most important aspects of root canal therapy and prerequisite for the success of endodontic treatment. Apical transportations can jeopardize the outcome of treatment due to the significant decrease in the sealing ability of root filling material. The purpose of this study was to evaluate transportation in type II c...

Study Design: Prospective randomized controlled trial Aim: The aim of the present study was to clinically and radiologically evaluate two root canal filling materials in infected deciduous teeth over a period of 6 months. Background data: Pulp treatment in deciduous teeth is challenging due to the complex anatomy of the root canal system. The limitations in biomechanical preparation and root ca...

BACKGROUND Apical periodontitis (AP) is an inflammatory disease around the apex of a tooth root. Reported prevalence of AP ranges from 27% to 83% while the data about most post-Soviet countries are still missing. Knowing the prevalence of AP within a certain population helps to plan the treatment need and evaluate the success of endodontic interventions. We aimed to collect data about prevalenc...

Instead of extraction this case report presents an alternative treatment option for a maxillary incisor with a vertical root fracture (VRF) causing pain in a 78-year-old patient. After retreatment of the existing root canal filling the tooth was stabilized with a dentine adhesive and a composite restoration. Then the tooth was extracted, the VRF gap enlarged with a small diamond bur and the exi...

The purpose of this study was to examine the physical properties of PEMA-TA/HX-based resins including 20 to 100% ethanol, for a root canal filling material. The values of the elastic modulus in the samples including ethanol were more than 250 MPa, being higher than the approximately 40 MPa of Gutte-percha (GP). The values of compressive strain in the samples increased in an ethanol concentratio...

The seal provided by root canal fillings after post space preparation was studied using a pressure-driven radioactive tracer assay. The coronal part of root canal fillings was immediately removed, using a hot plugger, to a remaining length of either 3, 5, 7, or 9 mm. Intact root canal fillings of 14 mm served as control. Application of air pressure of 130 mm Hg to the tracer solution drove it t...
