conclusions these findings showed that 25(oh)d insufficiency was highly prevalent in hd cases and higher amount of 25(oh)d levels prevent shpt. methods a prospective experimental trial of 180 hd patients (f: 81, m: 99, age > 14year) participated in the study. at base line, levels of 25(oh)d, intact parathyroid hormone (ipth), calcium (ca), phosphorous (p), alkaline phosphatase (alk p), and albu...

introduction: root canal treatment is based on elimination of intraradicular microorganisms. calcium hydroxide ca(oh) 2 is the most widely used material for canal dressing, however, enterococcus faecalis has been reported to be resistant bacteria in persistent apical periodontitis . the purpose of this study was to evaluate the efficacy of ca(oh) 2 on the elimination of intraluminal and intratu...

paraloid-mg(oh)2 nanocomposites were synthesized via sonochemical method. nanostructures were characterized by xrd and sem. thermal stability behavior of paraloid filled with magnesium hydroxide was investigated by thermogravimetric analysis (tga). the influence of mg(oh)2 nanostructures on the flame retardancy of the paraloid matrix was studied using ul-94 analysis. our results show that the m...

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...

statement of problem: recent literatures show that accelerated portland cement (apc) and calcium hydroxide ca (oh) 2 may have the potential to promote the bone regeneration. however, certain clinical studies reveal consistency of ca (oh) 2, as one of the practical drawbacks of the material when used alone. to overcome such inconvenience, the combination of the ca (oh) 2 with a bone replacement ...
