background intra canal medicaments are used to reduce the number of bacteria and reinfection in endodontic procedures. calcium hydroxide was introduced to endodontics by herman as an intracanal antimicrobial agent. objectives the aim of this study was to present an injectable formulation of calcium hydroxide then compare the final ph of this new formulation with metapaste and evaluate the effec...

abstract background: primary hyperparathyroidism is autonomous production of parathyroid hormone. after removal of adenoma, one of the surgeons concern is postoperative hypocalcaemia. there is no precise method to determine if patients have hypocalcaemia postoperatively. the purpose of this study was to determine the relation between parathyroid adenoma weights, postoperative serum calcium and ...

a bstract background: during women lives, frequently face the challenge of calcium reduction and absorption. decreased calcium absorption followed by a decrease in estrogen at premenopausal ages, low average per capita calcium intake among women, wrong nutritional behavior, and household income reductions and make them more susceptible to osteoporosis and related complications. the aim of this ...

introduction : supplementation with minerals like calcium has been shown to be effective in preventing bone loss and increasing bone density. thus, it can be assumed that if calcium supplementation is paired with bisphosphonates, greater benefit can be achieved. in this context, we decided to perform this animal study on ovariectomized rats to assess whether bisphosphonate supplemented with cal...

transport of pathogenic bacteria has been recently considered a major source surface and subsurface water contaminations. soil could affect transport or filtering of bacteria depending on its physical and chemical properties. calcium carbonate and calcium sulfate are two important minerals of arid and semi-arid soils that their effect on bacteria transport has not been investigated, yet. in thi...
