IRCT20120901010703N3 IRCT 2020-11-02 Esfahan University of Medical Sciences Effect of Two Types of High Power Lasers in the Treatment of Dentin Hypersensitivity Evaluation the Effect of Two Types of High Power Diode Lasers 810nm and 980nm in the Treatment of Dentin Hypersensitivity 2019-02-09 anticipated 70 Complete https://irct.ir/trial/51610 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Participants selection in the study will perform by simple randomization method, individually and with random number table tools. In this way, a number will be written in front of the name of each person from the list of clients, then a table will be designed based on the sample size of the study, and we'll blindly touch a number of table numbers. The selected numbers will be included in the study if they are eligible after the examination. The intervention will be performed in a parallel design, and the choice of individuals for Intervention or Control will be randomly performed with coin instruments.In such a way that for both people whose names are accidentally put in the list, the first person uses ِDiode laser 810 and the second uses Diode laser 980, and vice versa if it is tails, Blinding description: Patient and statistician are not informed of type of laser used. N/A Dentin hypersensitivity. Intervention 1: Intervention group: group treated by 810 nm laser, irradiation parameters are: power of 1 watt in a non-contact continues mode from a distance of 1 mm with the angle of 45 ° for 30 seconds with a sweeping motion. Treatments were carried out in two sessions, a weekly interval. The pain evaluated by using VAS (Visual Analyzing Scale) index by applying dry ice spray at all times. Intervention 2: Intervention group: group treated by 980 nm laser, irradiation parameters are: power of 1 watt in a non-contact continues mode from a distance of 1 mm with the angle of 45 ° for 30 seconds with a sweeping motion. Treatments were carried out in two sessions, a weekly interval. The pain evaluated by using VAS (Visual Analyzing Scale) index by applying dry ice spray at all times. Intervention 3: Control group: Without intervention. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is There is no more information
