Abstract
Introduction: Dental composite resins are dental cements made of synthetic resins. Synthetic resins evolved as restorative materials since they were insoluble, of good tooth-like appearance, insensitive to dehydration, easy to manipulate and inexpensive. Dental composites play a pivotal role in modern dentistry, offering versatile restorative materials for various clinical applications. Materials and Methods: Sample preparation of High strength Injectable composite (A) and bulk fill Flowable composite (B). Thermocycler machine and Micro Vickers Hardness tester (SHIMADZU) used to find the hardness. Results and Discussion: Flowable bulk-fill composites (Tetric EvoFlow Bulk Fill) and high-strength injectable composite (G-aenial Universal Injectable) show similar results in terms of hardness, which is statistically higher when compared with both traditional flowable composites (Filtek Supreme XTE Flowable Restorative and G-aenial Flo X) hardness. The same results were also reported by a previously done study by Luca Pezzato et al (2022). Injectable GC Composite: Injectable GC composites are typically made by GC Corporation. They often contain a combination of glass fillers and resin matrix. Conclusion: The hardness comparison between injectable GC composite and Tetric Flow composite would typically depend on various factors, including the specific formulations of these materials, curing techniques, and testing methods.
