  composite restorations, a new category of composite restorative materials has been introduced the so-called “bulk fill” composite resins. Bulk fill composite resins are assumed to be curable to a thickness of mm [13], develop lower polymerization shrinkage stresses [14]   Dental composite resins are types of synthetic resins. They are insoluble, aesthetic, insensitive to dehydration and easy to manipulate. Composite resins are most commonly composed of Bis-GMA monomers, a filler material such as silica and in some applications a photoinitiator. Dimethylglyoxime can be added to achieve flow

There are many reviews and book chapters that discuss the restorative applications of these materials. 1–3 This system is versatile, and many different dental materials can be derived by modifying the resin formulation and/or the resin-to-filler ratio.

Direct restorative materials such as sealants are derivations of composite resins, as are Resin composite restorative materials. N Ilie. Department of Restorative Dentistry, Dental School of the Ludwig‐Maximilians‐University, Munich, Germany.

The aim of this study was to investigate the mechanical properties and find out a relationship between wear resistance, hardness and compressive strength values of the three types of restorative materials. MATERIALS AND METHODS Three different composite resins were studied for this study as seen in Table 1.

Depth of cure of composite resins is crucial in determining the maximal increment thickness when restoring tooth cavities.

In restorations with conventional composite resins the thickness of each increment has been defined as up to 2 mm. Bulk fill composite. Moreover, the antibacterial activity was retained for at least 3 months.
