1- classification of Peri. radical ar Leison? (name)
1- Acute apical periodontitis
2- chronic apical periodontitis
3- Condensing osteitis/or) sclerotic ing osteomyelitis
4- Acute apical abscess.
5- chronic apical abcess. (suppurative)
2- (maxillofacial surgery point of view)
classification of peri. radiator Leison.
- pulpit is (reversible, irreversible) (pulp)
- periodontitis (chronic - Acute) (Periodontal area)
- (inja ro nagofte Ama fekonnam) osteomylitis (cortical bone t)
- periostitis (serous_purulent) (under periosteum)
- Sub-mucosal (under mucosa)
periodontitis classification? Csuvgoary)
- Acute:
Acute. apical
Acute. marginal
Acute. diffuse - chronic:
Abcess
cyst
granuloma
periodontitis classification? (Endo)
- Acute:
Acute Apical Periodontitis
Acute Alveolar Abcess (AAA) - Chronic
Chronic Alveolar Abscess (CAA)
Peri radical a✓ tissue const’s PDL and (?) and (?)
cement
Alveolar process
Etiology of Peri_radical ar. Leison
1- microbiology
2- mechanical. during RCT (mech-irritant
3- thermal (irritant/
4. chemical (irritant)
classification according to clinical sign?
- Acute (significant symptoms and pain) (swelling)
- chronic (mild or No symptom)

How bacteria can cause information.
bacteria and toxin + immunological Agent + tissue debris of pulp necrosis
can reach to peri-radiculav Area by Root canal foramens
(AND CUASE): informatory + immunological reaction
when informatory is self-limiting and short process.
when irritant is transient in nature
Explain mechanical irritant_during RCT?
-when instrumenting canals (over instrumentation)
- when overfilling
normal peri apical tissue?
- Normal Lamina dura
- PDL
- Not sensitive percussion and pupation
Etiology? (acute apical periodontitis) [endo]
first: extension of pupal inf. from pulp to periodontics
- Bacterial toxin
- informatory mediator
- overfill of obtu ration
- over instrumentation (trauma)
- irrigant with disinf agent
sign? (acute apical periodontitis) [endo]
- pain on bite
- Feeling of elevated tooth from socket
- Rapid onset
- Spontaneous slight pain
Sign? (Acute-Periodontitis) (maxine)
- Sensitive percusion
- if pulp Necrotized Already so (sensitive to heat)
- spontaneous pain
- feel elevation because involvement of PDL
Radiograph sign? (Acute. apical. periodontitis)
Endo
- thickening of periodontal ligaments
- No apical translucency
Radiological sign (maxi/to)
- Usually No sign
- on Peri apical Region: only wider periodontal
space are seen as well as large carries Leison
treatment: Acute apical periodontitis (endo)
- Adjustment of occlusion if evidence of hyper occlusion)
- removal of irritant or pathologic pulp
Treatment: Acute periodontitis (maxi 110)
-RCT
- Extraction
Symptom? (chronic apical periodontitis)
pulp necrosis 100 %):
sensitive to heat Cmaxillo)
tooth can be discoloured-(All topic)
symptom of pulpit is disappear (maxillo)
asymptomatic or slight discomfort (jessica)
No response to electrical_thermal (Jess)
(because pulp is Narcotized)
Etiology? (chronic Apical periodontitis)
( all topics ) permanent presence of bacteria with moderate virulence.
(Jessica) pulp Necrosis, usually a sequel to SAP (symp-apical-period ont.
Radiological (C-A-P)
• extensive destruction of periapical tissue (jess)
- Circumscribed bone Leison around apex (All -topics)
• Radiographic sign visible indicate: (maxillae)
bone resorption
PDL + Lamina dura disappear
Treatment? (chronic Apical periodontitis)
(maxillo) usually eliminate acute sign then causative therapy (RCT-extraction)
(All topic) RCT + Extraction
(Jessica) RCT
Etiology? (condensis ostitis)
(All Notes) permanent of bacterial toxins, caused by pulp necrosis (iv. puipitiy
(jess) C. 0 is variant of Asymptomatic apical periodontitis which
Represent in increase of Trabecular bone in response to
irritant
usually Leison around apices posterior mandibular teeth.
(can associated with any teeth)
sign? (condensing otitis)
(jess_asymptomatic/news) or discomfort or pain (pulpit’s)
- yes or no respond to electrical or thermal
- yes or No respond to palpation or percussion
(Ah) Asymptomatic /painful/
X-ray? (condensing otitis)
(Alt) lirregular diffuse concentric ◦ pacy around apex
(jess) diffuse_Concentric Radio opacity of Peri apical tissue
Treatment? (condensing otitis)
(Tess) RCT
(AH) RCT/extraction
DDG?
endostosis
Definition of condensing otitis?
