Abstract

Introduction: Experimental studies in the laboratory, less than 120 permanent teeth of children 7-12 years old. Application of fluorescent Diagnodent 2910 Lazer machine, monitor and evaluate changes in the level of mineralization of enamel, after causing destruction and re-mineral mineral with saliva and 0.615 percent NaF gel. Aim: This study aims to evaluate the level of remineralization of enamel after application NaF gel 0.615 percent in experiment. Method: The model of experimental research in the laboratory by the method of single-blind, comparison group, 120 small permanent teeth of children 7-12 years old were randomly divided into two groups of 60 teeth: group A: Causes Cancellation of mineral, distilled water rinse, soak your teeth with saliva; Group B: Causes Cancellation of mineral, water washed, soaked with saliva and tooth gel 0.615 percent NaF change the level of mineralization of enamel was assessed by Diagnodent Laserfluorescence machine 2910. Result: The average value measured on the level Diagnodent enamel mineralization of both groups at the beginning before demineralization was 3.92 + or - 2.70; degree of mineralization of the two groups after Phosphoric acid, demineralized with 37 percent in the 15" was 22.8 + or - 4.83; After four minutes re-mineral intervention Diagnodent index measured in group A (control) was 19.6 + or - 2.35, group B (interference with 0.615 percent NaF gel) was 5.40 + or - 3.65. Discussion: In the intervention group pressure 0.615 percent NaF gel for four minutes Diagnodent index measured in this group have significant mineralization (5.40 + or - 3.65) compared with mineralized after causing demineralization (22.9 + or - 4.73) with P = 0.0001; gel 0.615 percent NaF increased the level of mineralization of enamel after 4 minutes of exposure, degree of mineralization of enamel after 0. 615 percent NaF gel increased pressure difference statistically significant (P = 0.0001) compared with controls only in the 4-minute saliva Conclusion: The application of 0.615 percent NaF gel for 4 minutes is the remineralization effect of causing lesions of enamel mineral lost forever in experiment.
