IRCT20190422043343N1 IRCT 2019-07-19 Hamedan University of Medical Sciences The Effect of Different Desensitiser Protocols on Dentin Hypersensitivity Treatment Comparison of Effect of Fluoride Varnish, Gluma and Er: Cr: YSGG Laser on dentin hypersensitivity in patients with sensitive teeth: a randomized clinical trial. 2019-05-04 anticipated 35 Complete https://irct.ir/trial/39153 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: At first, participants are classified according to their initial sensitivity and then randomly divided into random classes in a randomized block to ensure that each group is in the same state of origin in terms of initial sensitivity. Block size and randomization method will be determined by another person Other than the therapists and evaluators. Given the fact that the stimulus air flow is effective in evaluating the effectiveness of the therapeutic methods compared to the adjacent teeth, only one treatment will be used in each jaw quadrant, Blinding description: This study is a double-blind study. One operator irradiate laser and apply densitisers , while the other operator will assess the sensitivity. Also, patients will not be aware of the treatment they will receive and on the teeth Patients whose therapeutic protocol does not include lasers will be targeted by the aiming beam. 2-3 Dentin hypersensivity. Intervention 1: Intervention group 1:laser: Laser Er, Cr: YSGG (Waterlase, Biolase Technology, Irvine, CA) perpendicular to the dentin surface by moving scanning movements at a distance of 1 mm with zero percent of air and water for 30 seconds with a frequency of 20 Hz and a power of 0.25 W (44.3J / cm2) whit M Z6 sapphire tip with a diameter of 600 micron and a length of 6 mm will be exposed on the sensitive teeth. Intervention 2: Intervention group 2 (fluoride varnish):A cotton roll for isolating the environment and preventing the varnish mix with saliva will be used. Then, a thin layer of Fluoride varnish (Ivoclar Vivadent), will be applied on the surface of the tooth with a disposable microbrush in accordance with the factory's instructions. Two to three layers of varnish will be applied to the surface of the teeth on the same day. Patients will be told to stop taking any food or carbonate drink for an hour after using varnish. Intervention 3: Intervention group 3 (fluoride varnish and laser): The varnish will be used similarly to the method used in group 2 on the teeth surface, and the varnish will remain in place for 60 seconds, and then the laser will be exposed with the same radiant profile of the group 1 on its surface. Intervention 4: Intervention group 4 (Gluma): A cotton roll for rubbing the Gluma (Heraeus Kulzer GmbH, Hanau, Germany) will be used with a gentle but firm motion on the tooth surface. After 30 to 60 seconds, the dentin will dry completely until The fluid will disappear and the surface will lose its gloss state. Intervention 5: Intervention group 5 (Gluma and laser): The Gluma will be used similar to that used in group 4 on the teeth surface. then, the laser will be exposed with the same radiant profile of the group 1 on its surface. 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 Due to the confidentiality of patient information, the decision to publish the participant information file has not yet been finalized.
