An in-vitro evaluation of the physical properties of a new bulk-fill composite
MetadataShow full item record
Dental composite is a synthetic resin that is used as a tooth coloured restorative material in dentistry. It became the material of choice in the dental field due to its superiority in strength and aesthetics (Garcia et al., 2006). Composite resin has favourable physical properties such as high wear resistance and shade stability. The main disadvantages are as follows: polymerization shrinkage which leads to marginal leakage; discoloration of the filling; postoperative sensitivity; and recurrent caries (Garcia et al., 2006). In order to decrease the application time of incremental layering techniques in conventional resin composite restorations, bulk-fill composites were introduced to the dental market with modifications in physical and mechanical properties. BulkFill composite can be applied in a single one-step increment layer of 4 - 5mm, saving considerable time during the clinical procedure when compared to the conventional composite layering technique of 2 mm (Leprince et al., 2014).
