Define the Anatomical Considerations
1. Neurovascular bundle associated with greater palatine foramen, e.g. palatal root of the upper 1 st molar: Don't do incision at this area!
2. Mandibular canal,
3. Mental foramen "with the plexus",
4. Maxillary sinus,
5. Nasal floor,
6. If you did a perforation?
- Put a resorbable membrane "regeneration"
- Tell the patient not to sleep with the head downward.
- Antibiotics.
** What if the lesion is reaching the nasal floor?
- Do dissification ???? and avoid perforation.
7. Number of root canals.
