introduction: the aim of this study was to compare the discoloration potential of calcium-enriched mixture (cem) cement, white mineral trioxide aggregate (wmta) and calcium hydroxide (ch), after placement in pulp chamber. methods and materials: access cavities were prepared in 40 intact maxillary central incisors. then, a 2×2 mm box was prepared on the middle third of the inner surface on the b...

introduction: the aim of this randomized controlled trial was to compare the radiographic and clinical success rates of direct pulp capping (dpc) using proroot mineral trioxide aggregate (mta) or calcium enriched mixture (cem). methods and materials: a total of 42 symptom-free carious vital primary molars (21 pairs) were selected in this split mouth trial and randomly pulpotomized in two experi...

human dental pulp inflammation can progress to periapical lesion formation and conventional root canal treatment (rct) has been the traditional method for disease management. this observational study presents two cases of vital pulp therapy in mature molars diagnosed with irreversible pulpitis and associated with apical periodontitis. in these two clinical cases, the involved teeth had deep car...

introduction: microleakage is of the causes of endodontic treatment failure. the aim of this in vitro study, was to compare the microleakage of mineral trioxide aggregate (mta) and calcium-enriched mixture (cem) cement apical plugs in three environments. methods and materials: a total of 130 human extracted single rooted teeth were collected. after decoronation, preparation of the root canal sp...

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 ...

A review of the existing literature was performed by using electronic and hand searching methods for CEM cement from January 2006 to December 2013. CEM cement has a different chemical composition from that of mineral trioxide aggregate (MTA) but has similar clinical applications. It combines the biocompatibility of MTA with more efficient characteristics, such as significantly shorter setting t...

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...

the present report reviews the diagnostic and treatment challenges of a mandibular molar with previous root canal treatment and signs of a procedural mishap, i.e. furcal radiolucency and localized swelling of the gingival margin in which a sinus tract was present. by tracing the sinus tract, it became evident that the lesion originated from the furcation area, not the root apices. this case was...

this case report presents conservative management of unset mineral trioxide aggregate (mta) after being placed as a root-end filling material following periapical surgery. periapical surgery was indicated for a maxillary lateral incisor of a 15-year-old male due to persistent exudate and a large periapical lesion. during surgery angelus mta was placed as root-end filling. the next session it wa...

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...
