Abstract
Aim:The purpose of this study was to compare the bond strengths of stainless steel brackets and ceramic brackets after treated with conventional visible light and argon laser.Methodology:Extracted 80 human premolar teeth were collected and stored in distilled water. They are classified into four groups. All teeth were placed in acrylic block where long axis of the tooth should be perpendicular to the mold's bottom. Teeth were subjected to ×10 magnification after debonding.Results:There is no statistically significant difference was found between the shear bond strength of argon laser and conventional visible light for stainless steel and ceramic bracket. Ceramic brackets had significantly increased bond strength than stainless steel brackets.Conclusion:Argon laser can be used for bonding orthodontic brackets using a visible light-cure orthodontic adhesive system, and ceramic brackets had significantly increased bond strength than stainless steel.
