Abstract

The objective of this study is to evaluate the preventive effect of the gel contends extract of Neem on specimens of bovine dentine submitted to the erosion in vitro. Eighty bovine dentine blocks (4X4 mm) standardized for the superficial microhardness and will be divided in 4 groups, in accordance with the treatment: C (control, base gel); F (fluoride gel, NaF 1.23%); N (Neem gel) and F+N (fluoride+Neem gel, NaF 1.23% and extract of Neem). After the application, will be removal of the respective gels, by 5 min, will be carried through 4 cycles of de-remineralization. Each cycle will understand demineralization for the immersion of the blocks in soft drink (30 mL, for 10 min) and remineralization in artificial saliva (1 h). After the 4 cycles the blocks will be analyzed of perfilometry, to measure the preventive effect of the gel. Initially the normality and the homogeneity of the data will be check and tested appropriate to be used (p<0.05). (AU)
