Background: To compare and evaluate orthodontic brackets base shape on shear bond strength. Materials & methods: A total of 70 maxillary central incisor orthodontic brackets (n=10/shape) were enrolled. SBS in Newtons (N) at bracket failure was recorded for each sample. The results were analysed using SPSS software. P- value less than 0.05 was considered statistical significant. Results: There was no statistical differences in mean SBS (N) between control (68.12 N) and all other test groups. There was statistically significant difference in mean SBS (N) between all base shapes of brackets (p<0.05). Conclusion: Higher SBS (N) for rectangle, flower, and football base shape indicates even stress distributions throughout the bracket base. Keywords: Shear bond strength, Orthodontic brackets, flower base.
