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...
background calcium infusion is used as a pre-treatment before calcium channel blockers to prevent hypotension. occasional cardioversion with calcium gluconate infusion is seen in patients with paroxysmal supraventricular tachycardia. several mechanisms have been suggested for mechanism. herein we report a case presenting with atrial fibrillation but cardioverted with calcium gluconate infusion,...
summer pruning and calcium spray could improve kiwifruits quality. in this study, effect of summer pruning in two times, 2 and 15 days after petal fall alone or in combination with %1 calcium chloride spray on fruit quality and mineral elements contents of ‘hayward’ kiwifruit was investigated. calcium sprayed four times 90 days after petal fall with 15 days intervals. the results showed that su...
calcium acetate is used as an oral phosphate binder to control hyperphosphatemia in patients with chronic renal failure. compared to calcium carbonate, control of hyperphosphatemia can be achieved at lower calcium administration with calcium acetate which likely reduces the risk of hypercalcemia. in this study, various formulations of calcium acetate tablets were prepared and their disintegrati...
Hyperphosphatemia has an important role in the development of secondary hyperparathyroidism and bone disease in patients with end-stage renal disease (ESRD). The most effective method of phosphate elimination lies with phosphate binders, the agent that more commonly used, calcium carbonate, is not an ideal binding agent. In this regard, calcium acetate has been reported to have more or at least...
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...
for finding out the effect of nitrogen and calcium carbonate fertilizers on nitrate and nitrogen accumulation in aboveground biomass, calcium concentration and dry weight of leaves of satureja hortensis l., a factorial experiment was carried out based on randomized complete block design with three replications in karaj in 2008. the nitrogen fertilizer was in four levels (0, 50, 100 and 150 kg. ...
introduction: the aim of this research was to study the effect of a 6-week supplemented diet on increasing bone density by measuring calcium, phosphorus and bone mineral density (bmd) in male rats. materials and methods: in this experimental study, 24 wistar male rats, aged between 15 and 20 days, were selected. the rats were randomly divided into 3 groups: immune system supplement (iss), iss p...
introduction: apexogenesis is a way to save vitality of open apex damaged teeth with mild or moderate pulp involvement. such teeth are not repaired through normal and usual treatments. this treatment provides usual and physiological conditions for root to develop in normal length. the aim of this study was to determine the success rate of apexogenesis according to the duration of pulp exposure....
