Abstract: 

Background and Aim: Bond failure between bracket and tooth is one of the problems in orthodontic treatments. Placement of bracket increases the accumulation of plaque and periodontal problems, different ways such as mouth rinses are used to control these problems. The purpose of this study was to evaluate the effects of Ortho kin and Oral B mouth rinses on the shear bond strength of orthodontic brackets, taken in the faculty of dentistry.
Materials and Methods: In this experimental study, the brackets were bonded with a self cure composite to 45 human premolar teeth. Then the teeth were divided into three equal groups. The samples of all three groups were stored in artificial saliva for two weeks. The samples of experimental groups were placed in Ortho kin and Oral B mouth rinses for 60 seconds twice a day. The shear bond strength (SBS) values and adhesive remnant index (ARI) scores of the groups were evaluated and the data were analysed statistically by one-way analysis of variance (ANOVA), LSD and Chi-square tests.  
Results: Control group was found to have the highest SBS for 15.27
±0.58 Mpa, followed by Oral B group for 10.11±0.94 Mpa. Ortho kin group had the lowest SBS for 7.59±0.59. The differences were statistically significant (P<0.001). Ortho kin group showed a higher frequency of ARI score of 2, but in Control and Oral B groups ARI score was 3. The differences were statistically significant (P<0.001). 
Conclusion: The application of Ortho kin and Oral B after bracket bonding decreased SBS but the values were well within the clinically acceptable range of SBS. It is suggested to use Oral B instead of Ortho kin due to the higher SBS.
