Evaluation of the Survival of Fissure Sealants Applied With Different Pretreatment Methods on Permanent First Molars: A One-Year Follow-Up

Etching: After polishing all teeth included in the study with a polishing brush, Vococid (Voca, Germany) etching gel will be applied to the surface and left for 15 seconds, then rinsed and dried.

The teeth randomly assigned to Group B will receive 5.25% NaOCl applied with a sterile cotton pellet for 60 seconds after acid etching, followed by rinsing and drying.

The teeth randomly assigned to Group C will receive Futurabond® M+ (Voco, Germany) applied with a brush following acid etching. After gently drying with air for 5 seconds, the bonding step will be completed by light-curing for 10 seconds.

After completing the pretreatment steps for all groups, Grandio Seal (Voco GmbH, Germany) will be applied to the pits and fissures on the tooth surface and light-cured for 20 seconds. The procedure will be completed after checking the surface.
