Multifarious bone cement and its applications in endodontics – A review

Polymethyl methacrylate (PMMA), commonly known as bone cement, is widely used in orthopaedic surgery, mainly for prosthesis fixation, stabilizing compressive vertebral fracture or filling bone defects. Bone cement is a potentially new repair material that has been investigated recently in dentistry because of its properties like low cytotoxicity, excellent biocompatibility and resistance to a moist environment. In Endodontics, bone cement can be used as a furcation repair material, retrograde filling material and in apexification. Modified bone cements are introduced by adding fillers, adhesives, antibiotics, and nanoparticles that make it well suited as an endodontic repair material. This review paper highlights the importance of bone cement and its possible applications in Endodontics.
