ortho and endo

correct crowding: align malposed teeth > facilitate access for plaque removal
uprighting: align, reduce/correct tissue defects, improve occlusion
correction of pathologic migration: extrusion, labial flaring, rotation
intrusion: correction of tissue defects, favorable crown:root ratio

occlusal forces no longer directed down the tooth > supraeruption
food impaction in the IPC of supraerupted tooth

selective coronoplasty > prevent additional destruction of supporting tissue
likely need fixed prosth

PERIODONTITIS AND OCCLUSAL TRAUMA MAIN!
MAYBE loss of posterior tooth support

remove deposits and resolve marginal inflammation

primary endo: endo infection from PA or accessory foramen into periodontium
primary perio: perio pocket deepens to apex, 2ndary pulp involvement
primary perio 2ndary endo: perio pocket infect pulp via acc. canal > PA lesion
true combine lesion: two indep lesions, PA and perio, coexist and eventually fuse

endo therapy first
removal plaque/calculus, non surg or surgical
evaluate tooth for residual pocket or bony defect
periodontal therapy (osseous resective surgery, regeneration)

might have pain but if no pain its perio
swelling within gingiva
VITAL PULP!

NO POCKETS
NEGATIVE VITAL PULP TEST
RL at apex

swelling around root
no vitality in pulp
RL anywhere along root
