Abstract
Introduction: Fissure sealants' (FSs) clinical success is closely tied to their proper application and ability to achieve good adhesion.
Aim: The aim of the study was to determine whether bonding agents with co-curing / staged-curing were more effective at retaining various RBS in permanent teeth than those without co-curing / staged-curing.
Materials and methods: 36 healthy extracted human premolars were selected and removed from debris/blood stains which were then mounted in acrylic resin with the buccal surface facing upward. The samples were etched with 37% phosphoric acid for 15 seconds and divided evenly into 2 groups I & II(n=18). Helioseal-F plus (group I) and Clinpro (group II). Each group was subsequently split into three subgroups, A, B and C (n=6). Subgroup A (No-bonding) was not received bonding agent. Prior to sealant application, subgroup B (Staged-curing) received bonding agent that had been cured. while subgroup C (Co-curing) received cured adhesive system after the application of sealant. Shear bond test was tested by using the universal testing machine. A post hoc Tukey test and ANOVA (analysis of variance) were used to analyse the data.
Results: The results showed that the shear bond strength of group I (Subgroup IB) and group II (Subgroup IIB) which interact with Staged-curing was much greater than that of the other groups.
Conclusion
In comparison to No-bonding and Co-curing using a bonding agent as Staged-curing prior to the insertion of an RBS in permanent teeth increased SBS.
