this case report represents the outcome of endodontic treatment in an infected mandibular molar with periradicular periodontitis and inherent poor prognosis of root canal treatment due to severe root curvature. the tooth was successfully treated by leaving the mesial root non-obturated, the canal orifices were coronally sealed with calcium enriched mixture cement and a definitive coronal amalga...

introduction: the aim of this in vitro study was to evaluate the effect of 2% chlorhexidine (chx) on the push-out bond strength (bs) of calcium-enriched mixture (cem) cement. methods and materials: root-dentin slices from 60 single-rooted human teeth with the lumen diameter of 1.3 mm were used. the samples were randomly divided into 4 groups ( n =15), and their lumens were filled with cem cemen...

internal inflammatory root resorption (iirr) is a rare condition of the root canal and if it is left untreated it may lead to destruction of the surrounding dental hard tissues. odontoclasts are responsible for this situation which can potentially perforate the root. many initiating factors have been mentioned for iirr, almost all causing chronic inflammation in the vital pulp. iirr is usually ...

background and aims: we aimed to assess the bond strength of composite resin to three pulp capping biomaterials; proroot mineral trioxide aggregate (pmta), root mta (rmta) and calcium enriched mixture (cem), using three bonding systems [a total etch (single bond) and two self-etch systems (protect bond and se bond)]. materials and methods: ninety acrylic moulds containing a 6×2 mm hole were div...

introduction: the aim of this randomized clinical trial split-mouth study was to compare the postoperative pain following use of mineral trioxide aggregate (mta) and calcium-enriched mixture (cem) cement as pulpotomy agents in carious primary molars. methods and materials: forty-seven children aged between 6-10 years old were enrolled in this study. each child had two cariously involved primary...

missing of mandibular second premolar is one of the most common types of tooth agenesis. in such cases, maintenance of the primary second molar, if possible at all, can prevent many treatment procedures in future. the present case report represents the endodontic management of a necrotic left mandibular primary second molar that had developed an abscess. considering the missing of the permanent...

introduction: the present study evaluated the element distribution in completely set calcium-enriched mixture (cem) cement after application of 35% carbamide peroxide, 40% hydrogen peroxide and sodium perborate as commercial bleaching agents using an energy-dispersive x-ray microanalysis (edx) system. the surface structure was also observed using the scanning electron microscope (sem). methods ...

introduction: the aim of this in vitro study was to evaluate the effect of various irrigants on the push-out bond strength of calcium-enriched mixture (cem) cement and mineral trioxide aggregate (mta). methods and materials: a total of 140 dentin disks with a thickness of 1.5±0.2 mm and lumen size of 1.3 mm, were randomly divided into 12 groups ( n =10) and 4 control groups ( n =5). the lumen o...

introduction: the aim of this in vitro study was to evaluate the tooth discoloration induced by calcium-enriched mixture (cem) cement and mineral trioxide aggregate (mta). methods and materials: forty five endodontically treated human maxillary central incisors were selected and divided into three groups ( n =15) after removing the coronal 3 mm of the obturating materials. in the mta group, whi...

introduction : teeth with irreversible pulpitis usually undergo root canal therapy (rct). this treatment modality is often considered disadvantageous as it removes vital pulp tissue and weakens the tooth structure. a relatively new concept has risen which suggests vital pulp therapy (vpt) for irreversible pulpitis. vpt with calcium enriched mixture (vpt/cem) has demonstrated favorable treatment...
