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 ...

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...

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: 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...

background and aims. the aim of this study was to compare the biocompatibility of calcium-enriched mixture ce-ment (cem), composite resin and nano-particled mineral trioxide aggregate (np-mta) using human gingival fibroblasts. materials and methods. a comparative in vitro cell culture study was carried out using 60 single-rooted teeth which were assigned to the following four groups: 1) untreat...

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...

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...

i ntroduction: the aim of the present study was to evaluate whether adding 2% chlorhexidine (chx) and 2.6% sodium hypochlorite (naocl) to calcium-enriched mixture (cem) cement would affect its setting time (st), or not. methods and materials: in this study, the setting time of cem cement was evaluated in three groups ( n =9) as follows: group 1; cem cement, group 2; cem cement+2% chx and group ...
