- Eruption sequence (Stage of dentition)
- Congenitally missing teeth
- Supernumerary teeth
- Crowding/Spacing
- Ankylosed teeth

mandibular condyle and neck
pathology (dentigerous cyst)
ameloblastoma
What is really important to do in a pano radiograph for ortho?
Always count the teeth
(look for congenitally missing teeth)
What do you do with supernumerary teeth?
Extract as soon as you can without harming the adjacent developing teeth
What is the issue with supernumerary teeth?
- Disrupt normal eruption
- Disrupt alignment and spacing
Where are supernumerary teeth most commonly found?
anterior maxilla
