简要总结
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.
详细描述
Interproximal enamel reduction (IPR) is a common procedure used during orthodontic treatment aimed to reduce mesio-distal tooth size dimensions to address lack of space (mild and moderate crowding), Bolton tooth-size discrepancy, correction of morphologic anomalies, tooth reshaping and management of gingival papilla. It is a practice that also offers an attractive alternative to overcome difficulty when extracting premolars and resolve the instability of overexpansion in non- extraction cases, improving the stability of the arches.
IPR may be exploited inconjunction with fixed appliance treatment, although its application with removable appliance treatment such as clear aligners is commonplace.
Clinically, the most accepted IPR techniques include air-rotor stripping with fine tungsten-carbide or diamond burs, handpiece or contra-angle-mounted diamond-coated disks, and handheld or motor- driven abrasive metal strips.
Some of these techniques can cause deep furrows and scratches that cannot be removed by polishing . In addition, these surface irregularities could promote the adherence of plaque bacteria and induce iatrogenic damage, such as dental caries, gingival inflammation, periodontal tissue breakdown, gingival recession and increased sensitivity of the shaped teeth to hot and cold temperatures.
Sometimes, after IPR, it is possible to have dentin hypersensitivity (DH), attributed to exposure to dentinal tubules. This clinical condition is influenced by various factors, including patient' s age, the severity of crowding, pathological tooth wear, hypersensitivity before treatment and the amount of the removed enamel.

Assestment of DH after IPR
时间窗: from 3 to 4 months
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.
