ABSTRACT:Aim: The aim of this in-vitro study was to evaluate and compare the flexibility and bond strength of stainless steel wire, glass fiber reinforced composite and polyethylene fiber reinforced composite used in splinting of traumatized permanent teeth.
Materials and methods: In this study, a total of 60 samples were prepared of which 30 samples were tested for flexibility and 30 samples were tested for bond strength. For both parameters, based on the splinting material used, the samples were divided into 3 groups with 10 samples in each group: Group 1- stainless steel wire (8 braid flat dead soft wire by Ortho-Direct®), Group 2- glass fiber reinforced composite (Interlig by Angelus®) and Group 3- polyethylene fiber reinforced composite (Ribbond by Ribbond®). For flexibility testing, three-point bending test was carried out and for testing bond strength, pull out stress test was carried out. The statistical analysis was done using ANOVA F test, followed by Dunnett’s multiple comparison test.
Results: For flexibility, no statistically significant difference (p>0.05) was found amongst the three groups at 1 mm deflection. Statistically significant difference (p<0.05) was found between Group 1 and Group 3 at 2 mm deflection. The difference between Group 1 vs Group 2, and Group 2 vs Group 3 was highly significant (p<0.001) at both 2 mm and 3 mm deflection. For bond strength, the difference between the mean load values for all three groups was found to be highly significant (p<0.001).
Conclusion: The highest flexibility was observed with polyethylene fiber reinforced composite, followed by stainless steel wire while glass fiber reinforced composite demonstrated the lowest flexibility. Polyethylene fiber reinforced composite showed the highest bond strength, followed by glass fiber reinforced composite, while stainless steel wire exhibited the least bond strength.
