Dental Numbering Systems and Notation

The video tutorial by Dr. Shwetanan covers three main tooth numbering systems used in clinical practice: the Universal Numbering System, Sigmondi Palmer Notation, and the FDI system. Each system is explained in detail, highlighting their advantages and disadvantages. The Universal Numbering System uses numbers and letters to denote permanent and primary teeth, respectively. The Sigmondi Palmer Notation divides the mouth into quadrants and uses symbols and numbers. The FDI system employs a two-digit code for each tooth, making it internationally recognized and computer-friendly. The video concludes with a call to action for viewers to like, share, and subscribe.
