Abstract

This study aim to evaluate and compare the deflection of premolar teeth cusps that filled incrementally with
conventional composite (Universal Ceram X One Sphere TEC TM) and various types of bulk fill composite
materials (Kerr SonicFillTM3 , 3M FiltekTM Bulk Fill and Shofu Beautifil Bulk Fill). In this study 40 human,
healthy maxillary first premolars were collected and large MOD cavity were prepared in them . According
to restorative materials, the teeth were haphazardly categorized in 4 groups (n=10 per group). Group I :
The teeth were filled with SonicFill™3 Kerr composite, Group II : The teeth were filled with Filtek Bulk
Fill, Group III : The teeth filled with Shofu Beautifil Bulk Fill composite, and Group IV : The Teeth were
filled with Dentsply Ceram X One Sphere TEC TM. By the aid of digital microscope intercuspal distance on
the tips of the cusps between two index reference points was measured pre preparation of the cavity , post
preparation, after 15 minutes of completion of fillings. The cuspal deflection was calculated by determination
of the changes in measurements. Inward cuspal deflection was occurred in all teeth after filling , minimal
cuspal deflection reported in all study groups that filled with bulk fill filling in comparison with group IV that
filled in layering technique with conventional composite. Greater cuspal deflection produced by Beautifil
Bulk Fill restorative in comparison with other groups. As a conclusion of this study that using of new bulk
filling restorative materials could dramatically minimize cuspal deflection.
