1
Q

A
- External surface
- External inflammatory
- Internal inflammatory
- Replacement resorption
2
Q
Cause of external surface resorption
A
Ortho
Heals as pulp is healthy, splint if mobile
Removing source stops resorption
3
Q
Tx of external inflammatory resorption
A
Pulp extirpation
nsCAOH 4-6wks then obturate
RC tramlines intact
Moth eaten appearance
4
Q
Radiographic appearance of replacement resorption
A
Ankylosis
Bone fused to dentine
Loss of PDL + lamina dura
5
Q
Radiographic appearance of internal inflammatory resorption
A
Ballooning of canals
6
Q

A
Calcified tissue healing - barely see fracture line
Connective tissue healing - fracture lines visible
Osseous healing - 2 separate entities, own PDL space
