Introduction: In 2016, a new approach to endodontics using CAD/CAM printed guides or splints emerged, mostly in pieces with pulp obliteration.

Objective: To analyze the literature on some current endodontic techniques for the treatment of pulp obliteration, such as static guided endodontics, dynamic guided endodontics, and guided endodontic microsurgery.

Methodology: PubMed, SCOPUS and Google Scholar databases were reviewed to find recent articles published on guided endodontics with the following keywords: "pulp obliteration", "CBCT", "static guided endodontics", "dynamic guided endodontics" and "guided endodontic microsurgery".

Results: Pulp obliteration is the narrowing of the dental pulp space, which is caused by extrinsic and intrinsic factors. CBCT helps to measure the path of the canal in the dental roots, in order to be able to perform the appropriate accesses in endodontics. Static-guided endodontics, also called Endo Guide, uses 3D printed directional guides made with CBCT and CAD/CAM. Dynamic guided endodontics combines images that are reproduced in real time, guiding access and angulation. Microsurgery is performed when there is a failure in root canal therapy, its success rate has been increasing thanks to the use of CBCT that helps to link the other techniques using templates that predict the procedure.

Conclusions: Pulp obliteration causes pulp sclerosis and necrosis which at some point will require root canal treatment, currently different techniques can be used such as static guided endodontics, dynamic guided endodontics, microsurgery in which they have to go hand in hand with the use of CBCT for planning, the choice of these depends on the complexity of the case.
