Intraoral evaluation of mineralization of cosmetic defects by a toothpaste containing calcium, fluoride, and sodium bicarbonate.

摘要: New dual-phase fluoride toothpastes that contain soluble calcium, phosphate, and baking soda have recently been introduced into the market. These are designed to fill in small surface defects tooth enamel thereby enhance esthetics such as gloss. This two-part study was assess these superficial mineralizing effects from using one of products compared with an experimental calcium-containing, bicarbonate-free formulation a conventional toothpaste intraoral model. Enamel specimens 4 types were mounted appliance placed mouths volunteers for 1 month. The four whitening abrasion, coarse natural dimpling, acid etching. Before after exposure, scanning electron microscope photographs made. microhardness acid-etched also determined. brushed their twice daily three randomly assigned toothpastes. two-phase, bicarbonate-based toothpaste; experimental, toothpaste. Only calcium-containing showed unequivocal signs mineral deposition defects, leading smoothing enamel. All significantly increased hardness etched enamel, presumably because fluoride. However, only two gave greater increases than treated indistinguishable those saliva.
