introduction: the aim of this in vitro study was to determine the sealing ability of orthograde proroot mineral trioxide aggregate (mta) and calcium enriched mixture (cem) cement as root-end filling materials. materials and methods: fifty four extracted single-rooted human teeth were used. the samples were randomly divided into 3 experimental groups. in group a and b, 4 mm of wmta and cem cemen...

The aim of this study was to compare the antimicrobial and antifungal activity of MTA Angelus, Biodentine and DiaRoot BioAggregate tricalcium silicate based retrograde filling materials with agar diffusion test (ADT) method. Enterococcus faecalis and Candida albicans standard bacterial strains were used. 100 μl was taken from liquid cultures of E. faecalis and planted in Mueller Hinton agar and...

The purpose of this review was two-fold: (a) to determine which retrograde obturation material(s) best prevents dye/ink penetration in vitro; and (b) to determine whether in vitro results agree with in vivo results. A MEDLINE search was conducted to identify in vitro studies published between January 1966 and October, week 4, 2003, conducted on human teeth, and published in English, German, or ...

A 73-year-old man with unstable angina was found to have a severely calcified chronic total occlusion (CTO) of the mid left anterior descending coronary artery (LAD). Diagnostic coronary angiography confirmed the CTO to be complex, with a “flush” occlusion occurring in a segment associated with proximal septal and diagonal branches. Retrograde filling of the distal LAD occurred via 2 large sept...

BACKGROUND The functional significance of the anterograde and retrograde filling of coronaries on angiography is controversial. METHODS AND RESULTS Eighteen patients with 27 severe lesions (> 85% diameter stenosis) after previous extensive myocardial infarction were selected. The left ventricle was divided into 33 segments for regional comparison of epicardial flow (as assessed by angiography...

Quest for newer material are never ending especially in the field of dental science. Various materials have been formulated, tested, and standardised to obtain maximum benefits for good clinical performance .One such new material which was introduced is Biodentine which has numerous clinical applications. An ideal orthograde or retrograde filling material should seal the pathways of communicati...

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...
