A preliminary study of enamel remineralization by dentifrices based on RecaldentTM (CPP-ACP) and NovaMin® (calcium-sodium-phosphosilicate)

Acta odontol. latinoam; 23 (3), 2010
The purpose of this study was to investigate the enamel remineralization potential of two toothpastes, one of which was based on RecaldentTM (CPP- ACP) and the other on NovaMin® (Calcium-sodium-phosphosilicate). Human permanent molar teeth were subjected to three consecutive demineralization cycles. The...

Side effects of cyclosporine-A treatment in rats: gingival overgrowth and early hyperglycemia

Acta odontol. latinoam; 23 (3), 2010
Gingival overgrowth is an adverse side effect of cyclosporine A (CsA) in the treatment of transplanted patients. The purpose of this study was to evaluate the effects of CsA on new-onset diabetes mellitus and gingival overgrowth in rats, by measuring collagen, nitric oxide and microvascular permeability....
