Recharge pattern of contemporary glass ionomer restoratives.

Background: As glass ionomers have the ability to reload fluoride from outside sources, the aim was to compare the recharge pattern of six glass ionomer cements after exposure to fluoride.

Materials And Methods: Fuji VII, Fuji IX, Riva Pink, Riva Bleach, Ketac Fil and Fuji IX Extra were investigated. The fluoride-containing materials used were tooth paste and mouth wash (Colgate).

An angiographic consideration prior to coronary bypass graft surgery: importance of routine selective angiography of the internal mammary artery prior to myocardial revascularization.

The collateral perfusion via the hypertrophied internal thoracic arteries and rich anastomosis between the epigastric arteries reconstituting femoral artery are an important route in patients with peripheral vascular disease (chronic aortoiliac occlusion), providing blood flow to the lower extremities. Selective angiography of the internal thoracic artery plays a major role in the preoperative evaluation in patients with severe aortoiliac occlusive disease undergoing coronary bypass surgery and may prevent a major potential postoperative complication of acute lower extremity ischemia in these patients.
