Abstract

Objective: To evaluate the influence of Fluor protectors (1.5% amonium fluoride varnish) and white varnish (5% sodium fluoride varnish) in combination with diode laser on enamel micro-hardness.
Materials and methods: Fifteen maxillary premolar teeth will be selected and divided into six groups (N=15): Group 1: The control group; the samples were kept without any treatment in distilled water .Group 2: The AF group; the samples were treated with 1.5% AF gel for 4 minutes. Group 3: The NF group: were treated with 5% sodium fluoride gel for 1 minute. Group 4: The DL group: the specimens were irradiated by diode laser for 15 seconds. Group 5: The AFL group: the specimens were irradiated by the diode laser the same way as in group 4, and then they were treated with AF varnish as in group 2. Group 6: The NFL group: the specimens were irradiated by the diode laser the same way as in group 4, and then they were treated with NF varnish as in group 3.
Results: results show statistically significant difference between remineralization protocols P < 0.001.
Conclusion: diode laser irradiation increases enamel micro-hardness when used in combination with fluoride varnish.
