1

Symptomatic Apical Periodontitis

First extension of plural inflammation into PA tissues

2

Symptomatic Apical Periodontitis Irritants

Irreversible pulpitis --> inflammatory mediators
Bacterial toxins (from necrotic tooth)
Chemicals - NaOCl
Hyperocclusion - toot may still be vital, may be reversed
Overinstrumentation
Overextension of obturation material

3

SAP symptoms and signs

Spontaneous Pain
Acute pain to percussion
Hot, Cold, Electric sensitivity (pulpitis)
May or may not respond to vitality tests
May or may not have PA radiolucency
Widened PDL
HISTO -- macrophages, PMNs
May have liquefaction necrosis

4

SAP treatment

Vital -- Remove irritant and monitor
Necrotic -- RCT

5

Asymptomatic Apical Periodontitis

Pulpal necrosis
Sequel to SAP
Chronic

6

AAP signs and symptoms

Litte or no pain
No respose to vitality tests
Slightly senstive to palpation and perfusions
Wideneded PDL to extensive lesions

GRANULOMA
CYST

7

AAP treatment

RCT
Extraction

8

Condensing Osteitis

Variant of AAP
Most commonly the mandibular molar tooth

9

Condensing osteitis Irritants

Persistant irritation to the pulp - AAP

10

Condensing osteitis signs and symptoms

Increase in trabecular bone - Radiolucency
May or may not be painful

11

Treatment for condensing osteitis

RCT

If not addressed it may become infected

12

15

AAA treatment

Antibiotics
Possible I&D
Eventually RCT

16

Inflammatory lesion of plural origin - long standing

17

CAA irritant

Necrotic Pulp

18

CAA signs and symptoms

Assymptomatic
Not sensitive to biting
Feels different due to percussion
NO RESPONSE to pulp vitality testing
Apical radiolucency (LARGE)

MUCOSAL or FACIAL SINUS TRACT
(normal probing depths)

19

CAA treatment

RCT
