Universal numbering system (dental)
From Wikipedia, the free encyclopedia
The Universal numbering system is a dental notation system for associating information to a specific tooth, and is commonly used in the United States.
The designations "left" and "right" on the chart correspond to the patient's left and right, respectively.
[edit] Chart of codes
Orientation of the chart is traditionally "patient's view", i.e. patient's right corresponds to notation-chart right. The designations "left" and "right" on the chart correspond to the patient's left and right, respectively.
