Introduction:
The objective of this study is to assess and compare shear bond strength (SBS) using different bonding techniques in amelogenesis imperfecta (AI) cases.
Materials and Methods:
Totally 30 extracted premolars from AI cases and 10 premolars from normal cases were obtained. The first group of (10) normal samples was treated with 37% orthophosphoric acid (H3PO4), second group (10) of AI cases was treated with conventional technique (37% H3PO4), third group (10) with sodium hypochlorite (5% NaOCl), and fourth group (10) with 2% sodium fluoride (2% NaF). Brackets were bonded using Transbond XT light curing adhesive and SBS was measured using the Instron universal testing machine.
Results:
Statistically highly significant difference observed between the strengths of all four groups (P < 0.01) with the mean highest for control group followed by NaF conditioning and NaOCl conditioning and least for conventional bonding procedure in AI cases. On pairwise comparison using Tukey's post hoc test, statistically highly significant difference was observed between the mean SBS for control group versus Group 2, Group 3, and Group 4, Group 2 versus Group 3, and Group 2 versus Group 4.
Conclusion:
Brackets bonded by conventional technique showed lower SBS as compared to NaOCl and NaF in AI cases. The application of 2% NaF gel for 4 min before acid etching of hypomineralized tooth surface shows significantly higher SBS as compared to conventional and NaOCl group in AI cases.
