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: this laboratory study was performed to evaluate the effect of different acidic ph values on the push-out bond strength of calcium-enriched mixture (cem) cement. methods and materials: forty-eight root dentin slices were obtained from freshly extracted single rooted human teeth and their lumen were instrumented to achieve a diameter of 1.3 mm. then, cem cement was mixed according t...

introduction : root-end preparation and restoration with an endodontic material are required when nonsurgical endodontic retreatment has failed or is impossible. the present clinical study reports the treatment outcomes of periradicular surgery using calcium-enriched mixture (cem) cement. materials and methods: a prospective outcome study of periradicular surgery using cem was conducted on 14 p...

This study deals with the distribution of heavy metals in soils around one of the most important industries in Kingston, Jamaica i.e. the Carib Cement factory at Rockfort. The dust emitted from the Caribbean Cement Company Limited (Carib Cement), located in Rockfort, Kingston, gets deposited in course of time over the soil, leaves and forms a grey cover on the surrounding soils. Geochemical ana...

background: this study was designed to assess the microleakage of glass-ionomer (gi), mineral trioxide aggregate (mta), and calcium-enriched mixture (cem) cement as coronal orifi ce barrier during walking bleaching. materials and methods: in this experimental study, endodontic treatment was done for 70 extracted human incisors without canal calcifi cation, caries, restoration, resorption, or cr...

inflammatory external root resorption (ierr) after orthodontic treatments is an unusual complication. this case report describes a non-vital maxillary premolar with symptomatic extensive ierr (with a crown/root ratio of 1:1) after receiving orthodontic treatment. the first appointment included drainage, chemo-mechanical preparation of the canal and intra-canal medication with calcium hydroxide ...

introduction: the purpose of this laboratory study was to evaluate the effect of acidic ph on the sealing ability of calcium-enriched mixture (cem) cement and mineral trioxide aggregate (mta) apical plugs. methods and materials: seventy single-rooted human maxillary anterior teeth were recruited. the teeth were randomly divided into 4 experimental groups ( n =15), and 1 negative and 1 positive ...

i ntroduction: many of highly-alkaline dental materials have some adverse effects on physical properties of dentin. as basic substances, mineral trioxide aggregate (mta), calcium hydroxide (ch) and the new endodontic material, calcium-enriched mixture (cem) cement, may adversely affect dentin. the purpose of this in vitro study was to evaluate the effect of long-term application of cem cement, ...

crown fractures account for the majority of dental traumas if handled properly, prognosis of the pulp following a traumatic crown fracture can be favorable. the present case report focuses on the treatment of a traumatized mature permanent incisor with exposed pulp that was treated with the novel technique of miniature pulpotomy using calcium-enriched mixture (cem) cement. one-year follow-up re...
