background: to evaluate and compare the efficacy of mineral trioxide aggregate (mta) and traditionally used calcium hydroxide (ca(oh)2) in inducing root end formation of immature roots of traumatized young permanent anterior teeth. materials and methods: the study was carried out on 22 nonvital, immature permanent maxillary incisors. samples were allotted into two groups – group i mta and group...

objective: alzheimer’s disease is the most common type of neurodegenerative disorder. it has been suggested that oxidative stress can be one of the pathological mechanisms of this disease. carnosic acid (ca) is an effective antioxidant substance and recent studies have shown that its electrophilic compounds play a role in reversing oxidative stress. thus we tried to find out whether ca administ...

Widely used declarative approaches to generation in which generation speed is a function of grammar size are not optimal for real-time dialog systems. We argue that a procedural system like the one we present is potentially more efficient for time-critical real-world generation applications as it provides fine-grained control of each processing step on the way from input to output representatio...

background: the aim of this study was to evaluate the relationship between ultrasonographic findings and serum progesterone and cancer antigen-125 (ca-125) levels in threatened miscarriage and to predict pregnancy outcome. materials and methods: in a prospective comparative case-control study, serum ca-125 and progesterone levels were measured for 100 pregnant women with threatened miscarriage ...

Introduction: antimicrobial activity of irrigants and interappointment intracanal dressing is an important consideration in endodontics . The aim of this study was to evaluate the clinical efficacy of chemomechanical preparation of the necrotic canals with different irrigants and intra canal dressing in the control of root canal infection and sinus tract closure. Materials &Methods: In this ...
