Is Deep margin elevation a reliable tool for cervical margin relocation? - A comparative review.

The permanence of deep subgingival restorations are questionable both functionally and biologically. Crown lengthening is one of the traditionally performing procedures to visualize and relocate the deep margins, but the limitations of the invasive surgical procedure are anatomical complications like exposure of root concavities or furcation, violation of biological width, post operative discomfort because of sutures or periodontal packs; and less patient compliance. Other than crown lengthening, researchers tried some other techniques like modified matrix adaptation technique, using retraction cord, making holes in matrix band and flowing resin modified glass ionomer cement (RMGIC) to the root or cervical caries, orthodontic extrusion.

Static vs. dynamic navigation for endodontic microsurgery - A comparative review.

Digitalization of operative procedures through three-dimensional (3D) navigation is a remarkable advancement in the field of dentistry which allows both precision and accuracy while treating patients. It is an emerging technology with a wide variety of applications in dentistry. In the field of endodontics, these computer-aided 3D systems are being used for accessing and localizing canals in calcified teeth, removal of fiberglass posts, and in peri-apical surgeries etc.
