Endodontic surgery has now evolved to endodontic microsurgery. It has revolutionized the way surgery is perceived and performed by using state-of-the-art equipment, instruments and materials that match the biological concepts with clinical practice. Coupled with the introduction of magnification through the use of the surgical operating microscope, miniaturised armamentarium, refined principles of soft and hard tissue management, use of tissue regenerative root-end filling materials and enhanced principles of wound closure and postoperative management, surgical endodontics has emerged as a...

Tooth wear is a well recognized problem that has apparently increased in the last few decades. Various restorative materials may be used in erosion and abrasion lesions to restore tooth structure, function and esthetics, as well as to control hypersensitivity. The materials in our study were nanofilled composites, microfilled composites and resin modified glass ionomer cements. Since the longevity of these restorations depends on its properties, such as surface microhardness and wear resistance, the aim of our study was to assess the effect of erosive and abrasive challenges on the above...
