Abstract

Objectives: Evaluate the shear bond strength (SBS) of Alkasite-based restorative material and resin-based composite to primary teeth dentin with or without 38% silver diamine fluoride pretreatment.
Materials and Methods: A total of 52 extracted primary molars were ground to obtain flat dentin surface. Teeth were randomly allocated into 2 main groups according to the type of restoration used. Group 1 (n=26): Teeth were restored with Alkasite based restorative material (Cention Forte). Group 2 (n=26): Teeth were restored with composite resin (Tetric N-Ceram Bulk Fill). Each group was subdivided into 2 equal subgroups according to 38% silver diamine fluoride dentin pretreatment.
Subgroup A (n=13): Restoration was placed after 38%SDF dentin pretreatment. Subgroup B (n=13): Restoration was placed without dentin pretreatment. Shear bond strength test was performed using Universal testing machine. Mode of failure was assessed by stereomicroscope. Data were statistically analyzed via Two Way Analysis of Variance (ANOVA) to assess the effect of restorative material and dentine pretreatment on shear bond strength. Pearson chi square test was used to compare mode of failure between subgroups.
Results: Mean shear bond strength of Cention Forte was statistically higher than Tetric N-Ceram Bulk Fill (P=0.006). However, there was no statistical difference between subgroups (P=0.151) (with or without 38% SDF pretreatment).
Conclusions: Cention Forte performed better than composite resin. However, 38% SDF pretreatment did not influence bond of restorations to primary teeth dentin
