Colloquim 5th year Acute odontogenic infections

Question 1

Ondontogenic inflammatory diseases

Answer 1

1. Periodontitis
2. Periostitis
3. Abcesses and phlegmons
4. Lymphadenitis
5. Osteomyelitis
6. Sinusitis

1. Acute/serous and purulent/chronic
2. Acite/serous and purulent/chronic/ firbous and ossifying
3. -
4. -
5. Jaw and facial bones
6. Odontogenic

Question 2

Two main sources of odontogenic infection development

Answer 2

1. Periapical disease
2. Periodontal disease

1. Necrosis of pulp
2. -

Question 3

Clinical stages of odontogenic infection

Answer 3

1. Periapical osteitis
2. Cellulitis
3. Suppuration and localisation of inflammation
4. Lymphadenitis
5. Soft tissue abscess
6. Osteomyelitis
7. Complications of the inflammatory process

1. When infection penetrates alveolar bone, tooth sensitive to percussion, feels higher and no swelling of adjacent soft tissues
2. Infection spread to adjacent soft tissues-> Inflammation, swelling, painful palpation
3. Abcess/acute purulent periostitis/sub periosteal abcess->Pain on percussion, pressure and palpation
4. -
5. Submucosal/perimandibular/paramandibular/soft tissues of face and neck
6. Jaw and facial bones
7. Spread to cavernous sinus and brain-> due to lack of valves in facial veins and numerous anastomoses making spred easy

Question 4

Treatment of purulent wounds

Answer 4

1. Trepenation
2. Extraction

1. Relieves pressure on tissues
2. -

Question 5

Drainage after trepination

Answer 5

1. Passive/rubber smooth
2. Corrugated drains
3. Active drains

Provide dialysis and lavage of tissues

Question 6

Choice of anaesthesia

Answer 6

1. Depends of severity and prevelance of inflammatory process
2. Functional stage of organism

1. -
2. Abscesses and phlegmons within anatomical area-> local anesthesia, maxillary phlegmons under general anaethesia

Question 7

Medications used for Acute odontogenic infections

Answer 7

• Antibiotics
• Antimicrobials
• Antifungals
• Analgesics
• Antipyretics
• NSAIDs

Question 8

Indications for antibacterial therapy for orofacial infections

Answer 8

1. Rapid developent of inflammatory process and systemic symptoms
2. Non localised infection
3. Poor response to treatment
4. Recurrent infections
5. Post operative infections
6. Risk of developping endocarditis
7. Osteomyelitis
8. Actinomycosis infection

1. Fever, leukocytosis, general weakness, rapid heartbeat, lymphadenopathy
2. Spreads
3. -
4. -
5. -
6. Patients with compromised somatic status, heart disease, impaired immune system/systemic disease
