The Universal/National System for permanent dentition numbers teeth beginning with the right maxillary third molar labeled as tooth number 1, following around the maxillary arch to the left maxillary third molar, descending to the left mandibular third molar, and following around the mandibular arch to the right mandibular third molar labeled tooth number 32. |

 |
| Panoramic view of the mandible shows dental plates with screws (A) and bone ligature wires (B). There are multiple dental alloy restorations (amalgam fillings). From Harkins, 1994 |
There are root canal fillings with denture retention posts (A) and porcelain denture teeth with pins (B). From Harkins, 1994 |
A coned mandibular view shows a cubic zirconia crown (*). The zirconia is surrounded by porcelain (horizontal arrowheads). In the next tooth there is an endodontic root canal with gutta percha (arrows), an opaque rubber. The light shade of the teeth (vertical arrowheads) shows composite acrylic restoration. |
Mixed dentition in a child with permanent teeth plus retained primary teeth. The + marks developmental follicles for the third molar and the * marks permanent second molars. |
