-
Pressure Resorption
o
Etiology

Impacted teeth
Tumors/cysts
o
Factor
Pulp usually not involved
Resorption is arrested when cause is removed
o
Treatment
Remove cause
Summary
-
Covering of dentin by cementum and pre-dentin essential to resistance of the dental root essential for
resistance of the dental root to resorption
o
Damage to these tissues can start process
o
Bacteria and inflammation are part of the process
-
Treatments
o
Internal Resorption
NSRCT
Perforations
Long term Ca(OH)
2
– apexification techniques
MTA (proroot) repair
o
