Introduction and objective:
Digitalization in dentistry has its own platform towards success. 3Dimensional (3D) printing is one of the techniques having its own benefits in dentistry, especially endodontics. 3D printing has promoted the advancements of surgical and non-surgical endodontics. In current circumstances, digital teaching is the only mode of education and training. It has enhanced practices in endodontic training and education, and transformed teaching from typodont teeth to 3D-printed tooth models. Ques applications as well as limitations in endodontics. The aim of the study was to assess various 3D techniques, their applications and limitations in endodontics.

Review methods:
Data was collected from various review and research papers by using key words, such as 3D printing, dentistry, endodontics, 3D applications in endodontics, and 3D methods, from various data bases, e.g. Pubmed, Google scholar, Scopus, etc.

Brief description of the state of knowledge:
3D printing covers wide applications in dentistry, especially endodontics, and will be a power point in the near future with 4D dentistry on the way.

Modern dentistry is digitalized dental practice. 3D printing has wide applications in dentistry using various techniques, such as Fused Deposition Modeling (FDM), Stereolithography (SLA), Inkjet Printing, 3D Plotting/Direct Write Bio printing each having different applications in endodontic. 3D printing has transformed surgical and non-surgical endodontic practice, from typodont teeth to 3D-printed tooth models. The review itemizes 3D applications and their limitations in endodontics and dentistry, and the expected exponential growth in subsequent years.
