Abstract
Objective
To evaluate the efficacy of Neem (Azadirachta indica)
experimental gel for the prevention of erosive wear on bovine dentin, in
vitro.
Material and Methods
One hundred dentin blocks were allocated into 5 experimental groups (20 samples
each): C (control group, without gel); CG (control group, only base gel); F
(fluoride gel, 1.23% NaF; pH 4.1, Dentsply; Brazil); N (Neem gel, 10% neem
extract; pH 4.1, manipulation); NF (Neem+fluoride gel, 10% Neem extract and 1.23%
NaF; pH 4.1, manipulation). The blocks were stored in artificial saliva for 24
hours. After this, they were submitted to six alternating re- and demineralization
cycles. The blocks were analyzed for wear (profilometry). The results were
submitted to statistical analysis by ANOVA and Tukey tests (P<0.05).
Results
The mean wear (±SD, µm) was shown as follows in groups: C (13.09±0.99), CG
(10.60±1.99), F (10.90±1.44), N (12.68±1.13) and NF (10.84±1.65). All gels showed
some preventive action when compared with control group. However, significant
differences were found only between Neem+fluoride gel and fluoride gel.
Conclusion
A single application of a neem-containing fluoride gel reduced dentin erosion,
thus it is a possible alternative in reducing dental wear. Further research should
investigate the action mechanism and the synergism between them.
