introduction: iatrogenic furcal perforation is a procedural accident in endodontic treatments of primary/permanent teeth; prognosis may be favorable if a complete seal with biomaterial is immediately established. the purpose of this in vitro study was to evaluate microleakage of calcium enriched mixture (cem) cement and proroot mineral trioxide aggregate (mta) for sealing primary molar furcal p...

introduction: some studies in dental literature have proposed that short term and long term exposure of root dentin to calcium hydroxide predisposes it to fracture. mineral trioxide aggregate (mta) and a recently introduced endodontic material, calcium-enriched mixture (cem) cement may be used instead of calcium hydroxide and might have an effect on the strength of root dentin. therefore, the a...

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 ...
