Comparative evaluation of microleakage amongst bioactive, hydrophobic and hydrophilic pit and fissure sealants: an in vitro study.

BACKGROUND

Pit and fissure sealants are widely used to prevent occlusal caries, but their effectiveness depends on adequate marginal sealing. Newer sealants with hydrophilic and bioactive properties have been introduced to enhance performance. The present study aimed to evaluate and compare the microleakage of bioactive, hydrophobic, and hydrophilic pit and fissure sealants in premolars. The aim of the present study was to evaluate and thereby compare the microleakage using bioactive, hydrophobic and hydrophilic pit and fissure sealant in premolars.

MATERIALS AND

METHODS

Forty-five extracted human premolars were randomly allocated into three groups of 15 each. Group A comprise of Helioseal F; Group B: UltraSeal XT® hydro TM and Group C: Bioactive BioCoat TM. Further, the teeth were subjected to thermocycling and immersed in 0.2% Rhodamine-B dye solution for a day. Buccolingual sectioning of teeth was done and evaluated under stereomicroscope. The mean score was subjected to one-way analysis of variance (ANOVA) to assess inter-group differences.

RESULT: Highest microleakage was seen in group A (1.13 ± 1.18) followed by group B (0.60 ± 0.91) and group C (0.46 ± 0.51). One way- analysis of variance was carried out and it was observed that no statistically significant difference was seen in all three groups (p = 0.119).

CONCLUSION

All three pit and fissure sealants demonstrated microleakage, with the bioactive sealant showing the least and the hydrophobic sealant the highest values.
