1. Key points in hx
Pain hx
and clinical
exam to come to
Clinical exam: pathology - caries, TSL,
an endo
diagnosis?
fracture TTP?
Swelling or
sinus TTpalp
Pocketing
In occlusion
Sensibility testing
Radiographs - pathology, bone levels, fracture
2. ENDO DIAGNO- Split into 3 sections
SIS - Coronal diagnosis - caries, fracture, TSL, cracks
- Pulpal diagnosis
- PA diagnosis
... bring together for a complete diagnosis.
