This study aimed to evaluate dental and periodontal health after interproximal enamel reduction and to compare Laser diode (a device used in the Orthodontic Program) and sodium fluoride (often used in the Orthodontic Program and in the Material Dental Program). The hypothesis was that the intervention groups would show a lower dentin hypersensitivity incidence than the control group during orthodontic treatment.

Sequential
Evaluation of Dentin hypersensitivity with VAS scale
Diagnostic testDentin hypersensitivity and periodontal indices evaluation are performed after and before IPR, at 1 week, 1 month and 3 months
Assestment of DH after IPR
Dentin hypersensitivity will be assessed before and after interproximal enamel reduction and after the application of therapeutic protocols. Dentin hypersensitivity will be performed with the evaporative method. After isolation of the adjacent teeth, the air syringe will be placed 2-3 mm from the tooth surface, at a perpendicular position of 90º, and a continuous air blast of 45 to 60 psi (3.10 to 4.13 Bar) should be applied for 2-3 seconds. The air temperature should be around 20°C (19-22°C). The discomfort will be expressed in a numerical 0-10 cm visual analog scale (VAS) where the value 0 is correlated with no discomfort and the value 10 for utmost discomfort or intolerable pain during application of the stimulus. Each patient will place a vertical mark on the VAS to indicate the intensity of his or her level of sensitivity after the applied stimuli.
Reduction of the Dentin Hypersensitivity

Evaluation of Dentin hypersensitivity after the application of therapeutic protocols.
Evaluate Dentin Hypersensitivity in the control group and the treated groups,with the evaporative method. After isolation of the adjacent teeth, the air syringe will be placed 2-3 mm from the tooth surface, at a perpendicular position of 90º, and a continuous air blast of 45 to 60 psi (3.10 to 4.13 Bar) should be applied for 2-3 seconds. The air temperature should be around 20°C (19-22°C). The discomfort will be expressed in a numerical 0-10 cm visual analog scale (VAS) where the value 0 is correlated with no discomfort and the value 10 for utmost discomfort or intolerable pain during application of the stimulus. Each patient will place a vertical mark on the VAS to indicate the intensity of his or her level of sensitivity after the applied stimuli. To assess in which group it reduces or is eliminated more quickly.
