Comparative study of Hydroxyapatite and fluoride containing tooth paste on inhibition of dental carries

Abstract

Though dental caries is the preventable disease but still grow and one of the most prevalent disease worldwide, particularly among the children. Several technique has been used to prevent or cure the dental caries like addition of the anti-bacterial in the toothpastes. Current study focused to evaluate the toothpaste containing fluoride and hydroxyapatite against the cariogenic bacteria isolated from the infected oral tooth. For this bacteria samples were collected from the dental plaque from the patients at dental clinics. Isolates were identified using biochemical tests and gram staining and antimicrobial activity was assessed through disc diffusion test. Result revealed that 6 species were identified (S. aureus, A. viscosus, Actinomyces, Rothia dentocariosa, Veillonella and Scardovia). Most dominated species was S. aureusfollowed by A. viscosus. When these isolated strains were tested against the toothpaste then it was found that toothpaste containing hydroxyapatite was more active against these targeted bacteria. besides this it was more active against the S. aureuson the other hands toothpaste containing fluoride was more active against Rothia dentocariosa and Veillonella. Overall toothpaste supplemented with hydroxyapatite was more efficient as compared to fluoride supplemented toothpaste.
