Objectives.
To investigate if reducing the light-curing time (while maintaining similar energy density) of resin-based surface sealants influences their erosion-preventive potential and mechanical stability after thermomechanical loading.
Methods.
Dentine samples were treated as follows: group 1—untreated, groups 2–4—Seal&Protect, groups 5–7—experimental sealer, and groups 8–10—Syntac Classic system.
Groups 2, 5 and 8 were light-cured for 10 s (1000 mW/cm2), groups 3, 6 and 9 for 7 s (1400 mW/cm2), and groups 4, 7, and 10 for 3 s (3200 mW/cm2).
After water storage (7 d), first measurement was performed to evaluate baseline permeability of the sealants.
After a thermomechanical loading (5000 cycles, 50/5°C, 12000 brushing strokes) a second evaluation of permeability was conducted (measurement 2).
Permeability was tested by storing the samples in HCl (pH 2.3; 24 h) and measuring the dentine calcium release by atomic absorption spectroscopy.
Results.
For the first and second measurements, no influence of light-exposure time on permeability was observed (ANOVA: P>0.05).
No significant difference in the stability of the respective sealants was observed when light-cured for different durations.
Conclusion.
Shortening the light-curing time, while maintaining energy density constant, has no influence on permeability and stability of the investigated sealants.
