| Abstract | ||
| Background: The main difficulties encountering clinicians with patients suffering from enamel defects are bonding of orthodontic brackets to these enamel defects as well as sensitivity due to sound dentin exposure. Aim: This study aimed at evaluating the effect of Potassium Iodide (KI) application on the bond strength of orthodontic brackets bonded to Silver Diamine Fluoride (SDF) pretreated sound dentin. Methodology: Upper premolar teeth (n = 36) were collected and were randomly divided into three groups (n = 12). Group I (control) untreated sound dentin, Group II exposed dentin pretreated with SDF and Group III exposed dentin pretreated with SDF/KI. An adhesive (Assure plus) was then applied strictly according to the manufacturing’s instructions. Then, each orthodontic bracket was bonded to the sound dentin surface using a direct resin composite. Fatigue bond strength test was performed via the step-test method. After debonding procedure of the brackets from the tooth surface, adhesive remnant index (ARI) scores on dentin were evaluated. Results: There was statistically insignificant differences in fatigue bond strength test results among the three tested groups as P > 0.05. Conclusion: Pretreatment of sound dentin with SDF or SDF/KI has no adverse effect on the bond strength between orthodontic brackets and sound dentin. | ||
