Severe traumatic injuries to immature teeth often cause damage to periodontal ligament as well as dental pulp; pulp necrosis, root resorption and subsequent apical lesion are common consequences. This article reports the surgical management of an infected immature maxillary central incisor associated with a gigantic periradicular lesion and severe root resorption. The tooth had a history of tra...

Abstract: Despite having a number of advantages, reinforced concrete can suffer rebar corrosion in high–chloride media, resulting in failure of reinforced concrete structures. In this research the corrosion inhibition capability of the mixture of calcium and ammonium nitrate of steel rebar corrosion was investigated in the simulated concrete pore solution. Cyclic polarization and Electroche...

studies show that there is a substantial gap between the recommended daily calcium intake and what people actually consume. calcium food fortification is an effective method to increase daily calcium consumption. in the present study, the influence of three calcium salts at different levels was evaluated on physicochemical properties of set yoghourt such as ph, acidity, incubation time and syne...
