Abstract

Background: Though composite resins have received popularity as restorative materials because of their physical properties, there was a dearth in the research about fracture resistance among recently emerged composite systems including Tokuyama Estelite Sigma Quick, Admira Fusion, and Beautifil II LS nanohybrid composite systems.
Aim: To compare and evaluate the fracture resistance of maxillary premolars with class II mesio occluso distal cavities restored with Tokuyama Estelite Sigma Quick, Admira Fusion, and Beautifil II LS nanohybrid composite systems.
Materials and Methods: Current invitro research was conducted on 44 intact human premolar teeth- Eleven specimens were kept completely intact for control group (Group G1). Class II MOD cavities were done with high-speed handpiece and under constant irrigation in remaining 33 teeth, Group G2, Group G3, Group G4 were restored with Tokuyama Estelite Sigma Quick (Tokuyama Dental, Tokyo, Japan.), Beautifil II LS (Shofu, Germany.), Admira Fusion (Shofu, Germany.) respectively. SPSS version 20 software to analyse the data; and ANOVA followed by Tukey’s post-hoc analysis to compare the fracture resistance were used.
Results: With a fracture resistance of 1297.27±10.27 N, Group 1 (Control) had highest fracture resistance. Group 4 has the least fracture resistance (Admira Fusion). Every pairwise comparison was significant too.
Conclusion: Among the three materials studied, Beautifil II LS had higher fracture resistance and Admira Fusion had the least fracture resistance.
