conclusions there was no significant statistical difference between mta and cem cement in sealing ability (p > 0.05). results the mean apical penetration of dye in the mta group was 0.94 mm while in the cem cement group this was 1.17 mm. eighty percent of the mta group and 75% of the cem cement group didn’t have any dye leakage. the p level was greater than 0.05 (0.592). materials and methods e...

introduction : the purpose of this in vitro study was to compare the antibacterial activity of calcium enriched mixture (cem) with proroot mineral trioxide aggregate (mta) against enterococcus faecalis ( e. faecalis) in the presence/absence of dentin powder. materials and methods: two series of freshly mixed (10, 50, and 100 mg), set crushed powder (10, 50, and 100 mg), and pieces of uncrushed ...

introduction: the aim of this in vitro study was to evaluate the effect of calcium hydroxide (ch) on push-out bond strength of white mineral trioxide aggregate (wmta) and calcium-enriched mixture (cem) cement in simulated furcation perforations. methods and materials: furcation perforations, measuring 1.3 mm in diameter and 2 mm in height, were created in 80 human mandibular first molars. the t...

introduction: the aim of the present study was to evaluate the effect of different mixing techniques (conventional, amalgamator and ultrasonic mixing) on the physical properties the working time (wt), setting time (st), dimensional changes (dc) and film thickness (ft)] of calcium-enriched mixture (cem) cement and mineral trioxide aggregate (mta). methods and materials: the mentioned physical pr...

Mineral Trioxide Aggregate is a material developed for endodontics that appears to be a significant improvement over other materials for procedures in bone. It is the first restorative material that allows for the overgrowth of cementum and the regeneration of periodontal ligament. The present case report illustrates the use of MTA in treating a case of perforation in the furcation area with lo...

The most important factors determining periodontal healing after replantation of an avulsed tooth are the extra oral period and the media in which the tooth is preserved before replantation. This case report describes an adequate periodontal healing of an avulsed immature tooth replanted after 20 min of extra alveolar dry time. Vitality was not regained and after disinfection of the pulp space ...
