introduction : this investigation evaluates the effects of mineral trioxide aggregate (mta), calcium hydroxide (ch) and calcium enriched mixture (cem) as pulp capping materials on dental pulp tissues. materials and methods: the experimental procedures were performed on eighteen intact dog canine teeth. the pulps were exposed. cavities were randomly filled with cem, mta, or ch followed by glass ...

abstract statement of problem: the ph of the human abscess has been measured as low as 5.0. this low ph could potentially inhibit setting reactions, affect adhesion, or increase the solubility of root end filling materials hence affect the compressive strength. moreover, root end filling materials might expose or even mix with lidocaine hcl during periapical surgery. objectives: the aim of this...

introduction: the aim of this study was to compare the marginal adaptation of mineral trioxide aggregate (mta) and calcium-enriched mixture(cem) cement apical plugs in open apex teeth in dry, blood- and saliva-contaminated canals. methods and materials: a total of 120 human extracted single-rooted teeth were used. the teeth were decoronated and canals were cleaned and shaped up to #80 k-files. ...

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 purpose of this study was to compare the sealability of three different commercial types of mineral trioxide aggregate (mta) and calcium enrichment mixture (cem) cement as an experimental root-end filling material. materials and methods: forty-six single rooted teeth were cleaned, shaped, and obturated. the apical 3 mm of each root was resected and root-end cavities with 3 mm ...

for management of a symptomatic maxillary lateral incisor with dull pain on chewing, suppurative sinus tract, defective metal-ceramic crown and iatrogenic internal root resorption, an interdisciplinary approach was taken. two-visit nonsurgical treatment with calcium-enriched mixture (cem) cement, replacement of metal-ceramic crown with all-ceramic crown and corrective periodontal plastic surger...

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...
