Objective: The objectives of the present study were to evaluate and compare the shear bond strength (SBS), and the flexural strength (FS) of zirconia reinforced glass ionomer (Zirconomer) and two conventional glass ionomer cements commonly used in atraumatic restorative treatment (ART).
Materials and methods: The bond sites for SBS testing were prepared on enamel (n = 45) and dentine (n = 45) on caries free, extracted human permanent molars. The specimens were randomly divided into six groups (n = 15) for each restorative material and site (dentine or enamel) tested. They were loaded in an Instron Universal Testing Machine (UTM) at a crosshead speed of 0.5 mm/min for SBS and 1.0 mm/min for the three-point FS test until failure occurred. Mode of failure was assessed using stereomicroscope (10×).
Results: Ketac™ Molar (KM) demonstrated the highest mean SBS to enamel and significantly higher mean SBS to dentin in comparison with the other groups. Zirconomer and Fuji IX GP Extra (FJ) showed comparable SBS to enamel and dentin. KM also demonstrated significantly higher FS in comparison to the other groups.
Significance: Within the limitations of the present study, Zirconia reinforced glass ionomer cement (GIC) can be an alternative to conventional GICs for application in ART. However, further studies are required to prove its clinical performance in the clinical scenario.
