Microleakage of Different Pit and Fissure Sealants

Background/Aim: Sealing pits and fissures is considered to be an effective way of preventing caries initiation. The present in vitro study was carried out to evaluate the microleakage and sealing ability of Helioseal F, Seal-it and GCP Glass seal and Compared sealing ability of GCP Glass seal with resin fissure sealants. Materials and Method: 80 extracted premolars free of caries, cracks or morphogenic diversity were collected and distributed equally in four groups (20 in each). Group-I (Helioseal F), Group-II (Seal-it), Group-III (GCP Glass seal) and Group-IV (GCP Glass seal without etching). Samples were cleaned with pumice slurry and etched with phosphoric acid etchant except Group-IV without etching. Air and water sprays were used for washing and drying, the teeth were treated with sealants followed by thermocycling and immersion in methylene blue dye for 48 hours. The samples were sectioned and examined under a stereomicroscope at x15 magnification then the score was given for microleakage. The sections were photographed to show a score of “0”,“1”,“2” or “3” microleakage and the data was statistically analyzed with Chi-Square test. Results: Seal-it material was the best sealant material as it was showing significantly least microleakage as compare to Helioseal F and GCP Glass seal and the microleakage was found to be the highest for the GCP Glass seal with etching. Conclusion: According to the results, the Seal-it material was found to be an excellent dental material for pits and fissures and GCP glass seal should be used without etchant.
