The bond strength of group 3 (mean: 36.7 +/- 11.8 MPa) was significantly higher than group 4 (mean: 26.6 +/- 8.9 MPa; P < 0.05), group 1 (mean: 25.5 +/- 5.1 MPa; P < 0.01), and group 2 (mean: 22.9 +/- 7.3 MPa; P < 0.001). No significant differences in debond locations were found among the groups (P > 0.05). Compared with conventional acid etching, SEPs significantly decreased the SBS of ceramic orthodontic brackets.
