Aim: To evaluate and compare the shear bond strength (SBS) of resin-modified glass ionomer cement (RMGIC) to primary teeth dentin pretreated with silver diamine fluoride (SDF) and sodium fluoride (NaF) varnish.
Materials and methods: Sixty samples of noncarious human primary molars were collected for the study. Teeth were prepared to expose a flat dentin surface and teeth were randomly divided into two groups. In group I primary teeth dentin surface was pretreated with SDF 38%, while group II samples were pretreated with NaF varnish 5%, then the samples were restored with RMGIC. SBS was evaluated using a universal testing machine.
Results: The results of the study showed that the mean SBS of group I was significantly higher (11.64 ± 6.78) as compared to group II (7.90 ± 4.96) with a mean difference of 3.74 MPa.
Conclusion: Primary teeth dentin surface pretreated with SDF 38% had shown an increase in the SBS to RMGIC when compared to NaF 5% varnish.
Clinical significance: Bonding of restorative material to primary teeth dentin pretreated with caries-preventing agents has shown good adhesion to the dentinal surface. It is a simple, minimally invasive procedure that can be beneficial in the pediatric population.
