DESENVOLVIMENTO DE PASTA PROFILÁTICA FLUORETADA CAPAZ DE FORMAR FLUORETO DE CÁLCIO NO ESMALTE DENTAL

Abstract

The use of fluoride products by professionals aims to form a reservoir of calcium fluoride (CaF2) on the surface of the tooth, as it is released slowly, so as to interfere with the process of caries formation. In this context, prophylactic pulps appeared combined with fluorine (F) to combine cleansing and prevention. However, in a recent study, it was observed that formulations found on the market do not achieve significant anti-caries benefit because they lack the potential to form CaF2 on the tooth structure. Objective: The objective of this work was to develop a prophylactic paste with a formulation that favors the in vitro formation of CaF2 reservoirs in dental enamel. Materials and Methods: For analysis of the formulation, eighteen blocks of bovine enamel were used as substrates for application in 6 experimental groups (n = 3): fluorine gel acidulated 12,300 ppm F (anti-caries positive control), fluorine neutral gel 9000 ppm, fluoride prophylactic pulp formulation (experimental group), Pert-X SS White and Clinpro Prophy Paste 3M fluoride commercial pulps; and distilled and deionized water (negative control). CaF2 was extracted alkali, measured by fluorine specific electrode and estimated in μF / mm2. The results obtained were compared by KrulsKal-Wallis test followed by Dunn. Results: Experimental prophylactic paste was able to form CaF2 similarly to acidified fluoride gel (p> 0.05), and significantly higher than the commercially available paste (p <0.05). Conclusion: The formulation of abrasive fluoride paste, low pH and high concentration of fluoride, favored the formation of CaF2 in dental enamel like products of professional use established in the literature, and shows to be a promising strategy to reduce time and cost in the dental procedures.
