The aim of this study was to evaluate the bond strength, penetration ability, microleakage, and remineralisation capacity
of glass ionomer-based fissure sealant materials.
In this study, three glass ionomer-based fissure
sealants were evaluated (Fuji Triage, Fuji VII EP, and GCP Glass Seal). A dye-penetration test was performed to evaluate microleakage
under a stereomicroscope. The materials were applied to occlusal tooth surfaces, and bucco-lingual sections (1 mm width) were
assessed to evaluate the penetration ability. Shear bond strength of tested materials was assessed using a universal testing machine.
Finally, the remineralisation capacities of the materials were evaluated with EDS.
The Fuji Triage exhibited the lowest
microleakage and unfilled area proportion (p<0.05). The highest shear bond strength was calculated with Fuji VII EP (p<0.05). The fluoride content for all treatment groups was significantly different when remineralisation values were compared to demineralisation (p<0.05).
Both the Fuji Triage and Fuji VII EP yielded compatible and satisfactory results and all fissure sealants
used in this study are sufficient as anti-caries agents.
