Study Title:

Zinc: A precious trace element for oral health care?

Study Abstract

This review will discuss the importance of Zinc in the maintenance of oral health. Zinc (Zn) is a trace element of valuable importance. In the oral cavity, it is naturally present at various sites such as dental plaque, dental hard tissues and saliva. It is proven to be effective against common prevalent oral health problems such as dental caries, gingivitis, periodontitis and malodour. It is being used in various oral health care products to control the formation of dental plaque and inhibiting the formation of dental calculus. It has the potential to sustain and maintain its elevated concentrations for a longer time particularly in the dental plaque and saliva on delivery from the mouth rinses and toothpastes. It has been reported that low concentrations of zinc have the capability to reduce dissolution and promote remineralization under caries simulating conditions. Most importantly low Zn2+ levels in the serum are useful as a tumour marker. Thus taking a note of its potentials, it can be concluded that zinc is a precious element for the maintenance of oral health.
