Study Notes
Recording Patient Treatment with Accurate Dental Records
- Accurate dental records are crucial in any dental practice, and a code or numbering system is necessary to expedite documentation.
The Universal Numbering System
- The Universal Numbering System was first suggested by Parreidt in 1882 and officially adopted by the American Dental Association in 1975.
- This system is accepted by third-party providers in the United States and endorsed by the American Society of Forensic Odontology.
- The system uses numbers 1 through 32 to identify the 32 teeth in the permanent dentition.
- The numbering starts with 1 for the maxillary right third molar, moving around the arch to 16 for the maxillary left third molar, then dropping down to 17 for the mandibular left third molar, and increasing around the lower arch to 32 for the mandibular right third molar.
Universal Numbering System for Permanent Teeth
- Each permanent tooth is identified with a number from 1 to 32 (e.g., the maxillary right second molar is identified as 2).
- This system is used to identify each permanent tooth in illustrations and in the mouth.
Universal Numbering System for Primary Teeth
- The system uses 20 letters of the alphabet (A to T) to identify the 20 primary teeth.
- The letter A represents the maxillary right second primary molar, moving sequentially around the arch and through the alphabet to J for the maxillary left second primary molar.
- The sequence then drops down to K for the mandibular left second primary molar and continues clockwise around the lower arch to T for the mandibular right second primary molar.
- This system is used to identify each primary tooth in illustrations and in the mouth.
