Aim: The study evaluated the use of self-adhering flowable composite as a fissure sealant and compared it with a resin-based pit and fissure sealant.

Materials and methods: Forty children were selected for the study and all their four permanent first molars were subjected to fluoride free pumice oral prophylaxis. Their occlusal fissures were then prepared with fissurotomy bur using high-speed handpiece under cotton roll isolation and low volume suction. Simple random sampling was done and accordingly a child either received either a resin-based fissure sealant or a self-adhering flowable composite on the prepared fissure. All the restorations were clinically evaluated using Ryge’s direct evaluation criteria for four times i.e., immediately after the treatment, at the end of 3rd, 6th and 12th month. The retention was evaluated using Horowytz criteria.

Results: The retention rate of Dyad flow after one year was significantly higher than that of Helioseal-F (p = 0.015). The marginal integrity of Dyad Flow was significantly better than that of Helioseal-F during every evaluation period (p < 0.05). Both retention and marginal integrity of both sealants were similar in maxillary and mandibular molars at all evaluation periods.

Conclusion: Dyad flow can be used as an alternative to the conventional fissure sealant.

Clinical significance: In pediatric dentistry, where shorter appointment time is warranted, the self-adhering composite has the edge over conventional fissure sealant.
