Bond Strength Of Different Adhesives On Decidious And Permanent Teeth

To assess microtensile bond strength test to enamel and dentin of three adhesive systems on deciduous and permanent teeth.

Method:

Opti Bond Solo Plus (KERR), Opti Bond FL (KERR) and Opti Bond XTR (KERR) were tested. SonicFill (KERR) was used as a material for build ups in combination with all the tested adhesives. Build ups were made on buccal surfaces of the extracted human molars. Twenty four hours after the build ups were made teeth were cut, using no trimming technique, into slabs and afterwards into sticks (0.9x0.9) for microtensile bond strength test. Test was performed using universal testing machine, cross speed 0.5mm/min. Failure modes were noted. Kruskal Wallis ANOVA  and Dunn’s multiple comparisons were used to assess the difference between the subgroups (deciduous/permanent, enamel/dentin), Mann Whitney U was used to assess the difference between the groups.

Result:

Conclusion:

There was no statistically significant difference between the groups. There was no difference when subgroups (deciduous/permanent teeth) were compared. Opti Bond XTR showed highest microtensile bond strength on dentin regardless of the subgroup (deciduous/permanent) of all the tested materials.
