Title Of Article :
The effect of different surface conditioning methods and curing protocols on bond strengths of two different fissure sealants
Abstract :
OBJECTIVE: To evaluate in vitro shear bond strength of two different resin-based fissure sealants [BeautiSealant (BS), UltraSeal XT hydro (UH)] associated with application of an acid etching (Ultra-Etch Acid) or a primer (BeautiSealant Primer) and two different polymerization modes (Standard mode; 10 s or Xtra power mode; 3 s) of a third generation light emitting diode (LED) light curing unit.MATERIALS AND METHOD: Eighty enamel surface samples were prepared from 40 extracted human third molar teeth. Samples were randomly divided into 8 subgroups according to fissure sealants, conditioning methods and polymerization modes (n=10); Group 1: Acid + BS+ Xtra power mode, Group 2: Primer + BS + Xtra power mode, Group 3: Acid + BS + Standard mode, Group 4: Primer + BS + Standard mode, Group 5: Acid + UH + Xtra power mode, Group 6: Primer + UH + Xtra power mode, Group 7: Acid + UH + Standard mode, Group 8: Primer + UH + Standard mode. An Instron machine (1.0 mm/min) was used to measure shear bond strength values. Data were statistically analyzed by using one-way ANOVA and Tukey’s test (p 0.05). RESULTS: Significant differences were detected between the groups (p 0.05). Shear bond strength values of all BS subgroups were significantly lower than UH subgroups (p 0.05). Highest shear bond strength values were obtained in Group 5 and the lowest was obtained in Group 1. CONCLUSION: Shear bond strength values of fissure sealants can be affected by surface conditioning methods and curing protocols.
