Abstract
Objectives: This study was performed to evaluate the clinical durability and presence of caries of three different types of pit and fissure sealants in young permanent first mandibular molars in children aged between 6-8 years. materials and methods: A total of 54 young first permanent molars were properly diagnosed, selected, and randomly assigned to three groups (n=18): Group (A): “Embrace Wet-Bond"; hydrophilic pit and fissure sealant.Group (B)“Helioseal-F"; hydrophobic pit and fissure sealant. Group (C): “Fisseal"; flowable composite pit and fissure sealant. Clinical evaluations of marginal integrity, marginal discoloration, and retention after sealant placement were carried out at 3, 6, 9, and 12 months. Results: the results revealed significant difference between the all studied groups in regard to marginal integrity, and marginal discoloration after 3,6, and 9 months of follow-up periods and non-statistically significant difference at12 months. Conclusion: the use of fissure sealant provides clinical outcomes for caries prevention in the young permanent mandibular molars.
