CHRONIC
 Sinus tract may be present
 Pus discharging
 Halitosis
 Radiographically ill-defined radiolucency seen
 Swelling absent generally
 No pain due to draining pus
 Acute chronic apical abscess can be differentiated from lateral periodontal abscess by sinus tracing

Sinus Tract
 Periapical abscess :- self healing, no treatment required for that will heal when endo done
 Periodontal abscess :- needs perio treatments
 GP TRACING is the test done to detect the origin of the sinus, to diagnose if perio or endo origin
 GINGIVAL DRAINING SULCUS :- mimicking pockets
But it’s not gingival pocket. Could be perio or endo origin

CONDENSING OSTEITIS
1. Excessive mineralization of the bone around apex
2. Radiopacity
3. Rct not necessary.
