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...

introduction: the purpose of this ex vivo study was to assess the effect of two root-end filling materials against candida (c) albicans . materials and methods: proroot mta and cem cement were compared immediately and 24 h after mixing, in two different concentrations (50 and 100 mg/ml). a total of 50 culture wells were used and divided into experimental (n=10) and control groups (n=5). those w...

Introduction. Vertical root fracture (VRF) is one of the most frustrating complications of root canal treatment. The prognosis of the root with VRF is poor therefore tooth extraction and root amputation are usually the only treatment options. However, bonding of the fracture line with adhesive resin cement during the intentional replantation procedure was recently suggested as an alternative to...

introduction: the antibacterial effects of calcium hydroxide (ch), mineral trioxide aggregate (mta), and calcium enriched mixture (cem) cement against various spp. of microorganisms were assessed in-vitro using agar diffusion test. materials and methods: a base layer of petri plates was made using muller-hinton agar. four cavities were made in agar and filled with freshly mixed materials after ...

background: one ideal property of a root-end fi lling material is its apical sealing ability. the aim of this in vitro study was to assess bacterial and dye microleakage of white and gray mineral trioxide aggregate (wmta and gmta), portland cement and calcium-enriched mixture (cem) cement used as root-end fi lling material, and to assess the agreement between these two test methods. materials a...

Introduction: Endodontic treatment failure is caused by the leakage of microorganisms and endotoxins, which leads to pathological lesions. Adequate seal of the root canal is essential to preventing recontamination and ensuring the long-term clinical success rate. Mineral trioxide aggregate (MTA) and calcium-enriched mixture cement (CEM) are common types of cement with adequate ...

severe traumatic injuries to immature teeth often cause damage to periodontal ligament as well as dental pulp; pulp necrosis, root resorption and subsequent apical lesion are common consequences. this article reports the surgical management of an infected immature maxillary central incisor associated with a gigantic periradicular lesion and severe root resorption. the tooth had a history of tra...
