IRCT2016052628092N1 IRCT 2017-10-31 Shiraz University of Medical Sciences Evaluation of the effect of nano hydroxyapatites serum on reduction of enamel staining after orthodontic debonding with two different finishing, polishing techniques. Evaluation of the effect of nano hydroxyapatites serum and two different finishing, polishing techniques on reduction of enamel staining after orthodontic debonding in comprehensive orthodontic patients; a randomized clinical trial. 2017-07-21 anticipated 20 Complete https://irct.ir/trial/22866 interventional Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Prevention. 3 Effect of nano hydroxyapatites serum on reduction of enamel staining after orthodontic debonding with two different finishing, polishing techniques.. Intervention 1: At the end of the fixed orthodontic treatment, brackets will be detached using a hand plier by gently squeezing the mesial and distal wings together. Removal of remnant resin will be done on all teeth by means of using carbide burs operated with low speed and water cooling used for 20 seconds. Then, randomly on one side of the mouth (Intervention group), carbide burs, followed by aluminum oxide discs (SofLex), will be used on the upper and lower premolars for finishing procedure. Randomization will be done by coin tossing. Then a rubber cup will be used in order to polish all teeth. All procedures will be performed by a single clinician and a new bur and rubber cup and disc will be used for each patient. To ensure complete resin removal, teeth will be evaluated under dental operating light with dental explorer. For all patients, the Nano Hydroxyapatite (Nano HAP) serum will be applied on the upper left and right first and second premolars (Intervention group), and the color alterations will be compared with lower left and right first and second premolars. Instruction for application of Nano HAP serum is as follows: a high concentration Nano HAP serum will be applied by the clinician on the teeth surface daily for 10 days, with a sponge on the head of the Nano HAP tubes for 2 to 3 minutes, and rinsed after 20 minutes with water. During the application of the solution, the teeth will be isolated with cotton rolls, according to the manufacturer’s instructions. A timetable will be given to the patients to control oral hygiene at home. Intervention 2: At the end of the fixed orthodontic treatment, brackets will be detached using a hand plier by gently squeezing the mesial and distal wings together. On the other side of the mouth, (Control group) after removal of the remnant resin by means of carbide burs, SofLex discs will not be used, just a rubber cup will be used in order to polish teeth. All procedures will be performed by single clinician and a new bur and rubber cup will be used for each patient. To ensure complete resin removal, teeth will be evaluated under dental operating light with dental explorer. The Nano HAP serum will not be applied on the lower left and right first and second premolars (control group), and the color alterations will be compared with the upper left and right first and second premolars. In order to optimize the results, the incisal third of the buccal surface of central incisors which is not affected by bonding and debonding procedures, is considered as the negative control group and will be evaluated by spectrophotometry analysis like other groups.
