Gas ozone group
Diode laser group
Participant received 32 g/m3 of gas ozone for 30 second.
Participant received an application of desensitized gel, fluoride and potassium nitrate gel , and a first step of an irradiation with diode laser for 20 second of interval, 808 wavelength, and power incrementation, from 0,2 till 0,6 W, not in contact. Then the second step of irradiation for 30 second in contact with dentine surface, 808 wavelength, and power incrementation, from 0,2 till 0,6 W. Then the surface was rinsed, and the irradiation applied for a third time again without the gel as the second step.
