Evaluation of white spot lesions around orthodontic brackets using different bonding agents – An <i>in vivo</i> study

Objectives: The objectives of the study were to assess white spot lesions around orthodontic bracket macroscopically using two different bonding agents – one with amorphous calcium phosphate (ACP) (Aegis Ortho) and without ACP (Transbond XT). Materials Methods: comprises 10 patients from 14 23 years age. Patients divided into control groups. Forty premolar teeth then observed (20 in each group). Bonding procedure was done brackets positioned on all four 1 st pre-molars pre-treatment photographs taken. experimental material used Aegis Ortho composite (study group) Transbond XT (control Debonding (by Wing deformation technique) performed after 16 weeks which led adhesive fracture at resin interface leaving essentially enamel. Then, follow-up taken evaluate each. Results: containing for purpose, provided lesser enamel demineralization than XT. Conclusion: is significantly more beneficial reliable, however, further investigations are also required understand its clinical performance better.
