INTRODUCTION The provision of an effective apical seal is an essential factor when choosing an appropriate material for success of root-end surgeries. Root-end resection, preparation and obturation should provide an adequate apical seal. The aim of this in vitro study was to investigate bacterial and dye microleakage of four different root-end filling materials and compare the efficacy of these...

INTRODUCTION This in vitro study compared the coronal microleakage of mineral trioxide aggregate (MTA), calcium-enriched mixture (CEM) cement and Biodentine as intra-orifice barriers. METHODS AND MATERIALS The study was conducted on 76 extracted single-canal human teeth. Their root canals were prepared using ProTaper rotary files and filled with gutta percha and AH-26 sealer using lateral con...

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...

o bjectives: the aim of this study was to evaluate marginal adaptation of mineral trioxide aggregate (mta), calcium enriched mixture (cem) cement, biodentine and bioaggregate in presence of normal saline and human blood. materials and methods: in this in-vitro experimental study, 80 extracted single-rooted human teeth were instrumented and filled with gutta-percha. after resect- ing the root-en...

vital pulp therapy (vpt) is the preferred conservative treatment for preservation of symptomatic pulps in immature permanent teeth. the present case report summarizes vpt of an immature permanent molar with irreversible pulpitis associated with apical periodontitis in a 9-year-old boy. cervical pulpotomy was performed and radicular pulp stump were covered with calcium-enriched mixture (cem) cem...

vital pulp therapy (vpt) of permanent mature teeth is continuously ascertaining to be a more reliable endodontic treatment. the purpose of this case report was to describe successful vpt of a mature mandibular left first molar with concurrent hyperplastic pulpitis, internal root resorption and periradicular periodontitis in a 35-year-old male patient. after complete caries removal and access ca...

Abstract In recent years, industrial byproducts have been converted into useful and valuable commercial items. Reusing these plays a crucial role to ensure the circular economy thereby safeguard environmental impacts. Ethiopia, Aluminate Sulphate chemical factory disposes of filter-cake waste materials in landfills that high silica content. The is using pure kaolin other raw for production Alum...

OBJECTIVE To compare biodegradable magnesium phosphate cement (Mg-cement), calcium phosphate cement (Ca-cement), and no cement on bone repair, biocompatibility, and bone adhesive characteristics in vivo in horses. ANIMALS 8 clinically normal adult horses. PROCEDURES Triangular fragments (1-cm-long arms) were created by Y-shaped osteotomy of the second and fourth metatarsal bones (MTII and M...
