| Abstract | ||
| Objective: The study aimed to assess the shear bond strength of four restorative materials that are widely used in pediatrics to NuSmile- Neoputty material. The restorative materials were two glass ionomers: Fuji II LC and Equia Forte Fil, and two dental resin composites: Cention N and Venus Bulk Fill. Materials and methods: A total of 164 specimens were used in the study. 160 specimens were used for the shear bond strength testing and failure mode analysis. Four specimens were needed for scanning electron microscopic investigation of NuSmile surface with and without application of MDP containing adhesive. Specimens were divided into four groups according to the restorative material bonded to NuSmile: Group I: Fuji II LC. Group II: Equia Forte Fil. Group III: Cention N. Group IV: Venus Bulk Fill. Further subdivision into two subgroups (A & B) was done according to application of the adhesive or not respectively. Results: Subgroups (IA) and (IIIA) revealed significantly higher shear bond strength values than other groups with no significant difference between them, followed by subgroup (IVA). Subgroup (IIA) revealed the least bond strength value. Conclusions: Fuji II LC glass ionomer and Cention N composite would be capable for inducing stronger bond with NuSmile- Neoputty compared to Venus Bulk Fill composite. On the contrary, the bond strength of Equia Forte Fil to NuSmile- Neoputty could not be considered satisfactory. Application of MDP containing adhesive can enhance the bond strength to Nusmile- Neoputty regarding Fuji II LC, Cention N, and Venus Bulk Fill. | ||
