Abstract: Introduction: Etching in orthodontics is the most important phase of brackets bonding and failure to achieve proper bonding may result in poor orthodontic results. Thus, many attempts have been made since years to achieve the best etching method in order to maximize orthodontic therapy effect and in other hand to minimize unnecessary rebonding of failed brackets during orthodontic therapy. Failure to do so, leads to prolonged orthodontic therapy including complications like unnecessary repeated checkup at orthodontic office. Aim of study: This study evaluates the impact of varying enamel etching times on the shear bond strength (SBS) of orthodontic brackets. Material and methods: Sixty extracted premolar teeth were divided into three groups etched for 10, 30, and 60 seconds. Results indicated that 30 seconds provided the highest SBS (11.58 MPa), while 10 seconds yielded satisfactory results (10.53 MPa) with minimal enamel damage. These findings suggest that a 10 - second etching time is suitable for daily orthodontic practice. Results and discussion: . The highest bond strength was found among the group of teeth etched for 30 seconds (11.58 MPa). However satisfactory shear bond strength results were found in the group of teeth etched for 10 seconds (10.53 MPa). The group of teeth etched for 60 seconds exhibited the lowest SBS (8.79 MPa). The larger number of teeth exhibited ARI index 1 (21 teeth). Followed by the ARI index 2 (15 teeth). ARI score 0 was present in 14 teeth. Lowest score was recorded with ARI index 3 (10 teeth). Conclusions: We consider that time of etching for 10 seconds is suitable in daily orthodontic clinical practice.
