To evalate the efficacy of iodoform-calcium hydroxide used as an intracanal medication in root canal therapy of deciduous teeth with periapical periodontitis.
Objective: To compare the clinical effects of calcium hydroxide iodoform (CHI) slurry and traditional intracanal medication such as formocresol (FC), camphophenic (CP).
To study the content alteration of bacterial endotoxin in the exudant from the root canals of periapical treated with calcium hydroxide as intracanal medicament.
To study the content alteration of bacterial endotoxin in the exudant from the root canals of periapical diseases treated with calcium hydroxide as intracanal medicament.
Methods dip 2% lidocaine or impede narcosis, use the acuity exonerative plane root slot cut endodontium,after drying overlay thin hydrochloride zinc and than using the zinc phosphate to mount.
The results of research show that the impurity of infusibility and metal ion has been removed after the leaching of calcium carbide residue, and the transform rate of hydrated lime up to about 88%.
Over time, some CO2 from the atmosphere drifts into all that cement in buildings and bridges, and reacts with the calcium oxide to form calcium carbonate again.
Limestone is refined to produce calcium oxide, or quicklime, for cement, in a reaction known as calcination, which releases a lot of carbon in the form of CO2.
But in fact, most of the CO2 emissions come not from the heating, but from the breakdown of limestone, which is calcium carbonate, into calcium oxide and carbon dioxide, or CO2.
It wasn't until 2004 that they found the cause of the problem was lime or calcium hydroxide, to give it its proper chemical name, which was being used in the construction of roads.
