简要总结

This RCT study aims to establish evidence-based decision comparing between self-adhering flowable composite Vertise™ Flow (Kerr, Orange, CA, USA) and conventional resin-based pits & fissure sealant Helioseal-F sealant (Ivoclar Vivadent AG, Schaan, Liechtenstein) with and without fissurotomy in sealant retention and prevention of occlusal pits and fissures caries in first permanent molars over a 12-month follow-up.

详细描述

This randomized controlled clinical trial aims to compare the retention and clinical performance of a self-adhering flowable composite and a conventional resin-based pit and fissure sealant, applied with and without fissurotomy, in newly erupted permanent first molars of children aged 6-8 years.

Occlusal pits and fissures are highly susceptible to dental caries in children, and long-term sealant effectiveness is strongly dependent on material retention and technique sensitivity. Self-adhering flowable composites offer simplified application with fewer clinical steps and may improve retention, especially in pediatric patients.

Eighty-eight children will be randomly allocated into four parallel groups (1:1:1:1): self-adhering flowable composite with fissurotomy, self-adhering flowable composite without fissurotomy, conventional resin-based sealant with fissurotomy, and conventional resin-based sealant without fissurotomy.

Sealant retention will be assessed as the primary outcome using Simonsen's criteria, while secondary outcomes include caries development, marginal discoloration, and marginal integrity evaluated using Ryge criteria.

Clinical evaluations will be performed at baseline, 3, 6, and 12 months.

研究组 & 干预措施

Self adhering flowable composite Vertise™ Flow with fissurotomy

Experimental

Vertise™ Flow (Kerr, Orange, CA, USA)

Chemical composition:

  • Resin: GPDMA, HEMA, BisGMA, catalysts.
  • Fillers: Prepolymers, silanated Ba-glass, SiO2,YF3 (70 wt%). This SAFC uses the adhesive monomer glycerophosphate dimethacrylate GPDM, a phosphate functional group that creates a chemical bond with the calcium ions of the tooth. GPDM monomers ensure a tenacious bond to enamel, evidenced by the strength known to all generations of the OptiBond adhesive family.
