Wear Resistance Of Bioactive With And Without Etching Vs. Conventional Resin-Based Fissure Sealants
Sponsor: Cairo University
Summary
This randomized clinical trial aimed to compare the wear resistance and clinical performance of bioactive versus conventional resin-based pit and fissure sealants over a 12-month period. Conducted on young adults with sound, caries-susceptible molars, the study evaluated three groups: bioactive sealants applied with and without etching, and conventional resin-based sealants with etching. Clinical assessments and 3D digital scans were used to measure sealant retention and wear. The study seeks to determine whether bioactive sealants, especially when applied without etching, provide comparable long-term protection and durability to conventional sealants, potentially simplifying application without compromising effectiveness.

Bioactive Sealant with Etching: Participants in this group received a fluoride-releasing bioactive pit and fissure sealant (BeautiSealant, Shofu) applied after etching the tooth surface with 37% phosp
This group received BeautiSealant (a bioactive giomer-based sealant) applied after etching the enamel surface with 37% phosphoric acid for 15 seconds. The etching process creates micro-retentive patterns in the enamel to enhance micromechanical bonding, potentially improving the sealant's retention and wear resistance while also benefiting from the bioactive material's fluoride release and enamel remineralization properties.
Bioactive Sealant without Etching: In this group, the same bioactive sealant (BeautiSealant, Shofu) was applied directly without acid etching. This simplified technique evaluates the sealant's effecti
In this group, BeautiSealant was applied directly to the tooth surface without prior etching. The goal was to simplify the procedure by eliminating the etching step, relying instead on the sealant's chemical bonding and bioactive properties (such as fluoride release and S-PRG technology) to maintain retention and resist wear, while reducing the risk of enamel alteration and improving clinical efficiency.
Conventional Resin-Based Sealant with Etching (Control): This group received a conventional resin-based sealant (Fisseal, Promedica) following standard acid etching. This technique represents the trad
This group served as the control and received Fisseal (a conventional resin-based sealant) applied following standard etching with 37% phosphoric acid. This method is considered the gold standard for fissure sealing, offering strong micromechanical adhesion and proven wear resistance, making it a reliable benchmark for evaluating the performance of newer bioactive materials.
