Terminology & Chronology Flashcards
What are the 3 ways to number teeth?
- Universal numbering system
- Palmer notation system
- FDI system of numbering
Using the universal system of notation, each tooth is numbered from what to what in the permanent dentition?
1-32
Using the universal system of notation, where do we start numbering teeth, what’s in the middle and where do we finish?
Maxillary right quadrant —> maxillary left quadrant—> Mandibular left quadrant —> Mandibular right quadrant
Number the teeth
1-32 starting in maxillary right quadrant and making a circle until you get to Mandibular right quadrant
