Study Notes
Introduction to Odontogenic Infection
- Dr. Hussein Abdel Motelep Khalil is a lecturer of oral and maxillofacial surgery at Sinai University Kantara.
- Odontogenic infection is an infection originating within a tooth or the surrounding tissues.
Definitions
- Infection: The invasion and growth of micro-organisms in the body, causing disease.
- Odontogenic: Caused by teeth.
- An odontogenic infection arises within the tooth or its close vicinity.
Microorganisms
- Micro-organisms can include bacteria, fungi, viruses, or other microorganisms.
- Transmissible spongiform encephalopathy is caused by prions, misfolded proteins resulting in brain damage.
Inflammation
- Inflammation is a protective response to harmful stimuli, like pathogens.
- This response involves molecular mediators, blood vessels, and immune cells.
- The five cardinal signs of inflammation are hotness, redness, swelling, pain, and loss of function.
Types of Inflammation
- Acute: Rapid, progressive response with typical signs and symptoms.
- Subacute: A transition phase between chronic and acute inflammation.
- Chronic: A prolonged course with milder symptoms and signs.
Pathogenesis of Odontogenic Infection
- The development of the infection can be visualized in a series of dental diagrams.
Dental Abscess
- A dental abscess is a localized collection of pus in the periapical tissues or surrounding areas.
Causes of Dental Abscesss
- Dental caries (cavities)
- Periodontal disease along with poor oral hygiene
- Trauma to the tooth
- Cracked tooth
- Gum surgery
- Immunodeficiencies (diabetes, chemotherapy, steroids)
Symptoms of Dental Abscess
- Sharp tooth pain that can fluctuate in severity
- Pain in the jaw, ear, and neck
- Worsening pain when lying down
- Sensitivity to temperature changes in food and drinks
- Unpleasant taste in the mouth
- Eating and swallowing difficulties
Treatment for Dental Abscess
- Removal of the source of infection (e.g., tooth extraction or root canal therapy) and draining the pus.
- Antibiotics to manage the infection and prevent complications.
- Supportive measures, such as pain relief and rest.
Pericoronal Infection
- A pericoronal infection involves the soft tissues surrounding the partially erupted tooth, including the gums and dental follicle.
- The operculum is the soft tissue covering a partially erupted tooth, which is often hard to clean.
- Inflammation of the operculum is called operculitis.
Causes of Pericoronitis
- Food impaction
- Trauma from opposing teeth
- Virulent microorganisms
- Low body immunity
Treatment of Pericoronitis
- Elimination of the root cause (eg. removal of food debris, smoothing the opposing teeth)
- Draining pus and administering antibiotics
- Definitive treatment may include impacted teeth removal (removing the operculum, if possible)
Microbiology of Odontogenic Infection
- Odontogenic infections are commonly mixed infections – containing both aerobic and anaerobic bacteria.
- Aerobic: Streptococcus milleri, Streptococcus sanguinis, Streptococcus salivarius, Streptococcus mutans, and Streptococcus viridans
- Anaerobic: Bacterioides, porphyromonas, and prevotella
Spread of Infection
- Cellulitis: Spread of infection into the loose connective tissue.
- Suppurative infection: Characterized by pus formation.
Differences Between Cellulitis and Abscess
- Cellulitis: Rapid onset, diffuse borders, typically pain is intense, and extensive
- Abscess: Localized, well-defined borders, fluctuating pain, pus is present.
Cellulitis
- Edematous spread of acute inflammation.
- Unable to establish drainage to surfaces, or oral or facial cavities.
- Has the potential of spreading diffusely through facial soft tissue planes.
Suppurative Infection
- A distinct infection characterized by pus formation.
Spread of Infection to Tissues
- The fascial spaces in the neck can be infected, and various spaces (e.g., prevertebral, retropharyngeal, lateral pharyngeal, and others in the neck) can be affected.
Factors Affecting Spread of Infection
- Virulence of microorganisms
- Immune status of the patient
- Anatomical features that influence spread direction
- Location of the infection source
- Pus escape pathway
- Anatomical barriers like muscles and fascial tissues
Sites of Infection
- Buccal space
- Canine fossa
- Submandibular space
Ludwig's Angina
- A severe form of cellulitis in the floor of the mouth.
- Swelling in the floor of the mouth, difficult swallowing, and drooling can be seen.
- Can have airway compromise and tongue swelling.
Management of Ludwig's Angina
- Airway management
- Aggressive antibiotic treatment
- Incision and drainage
- Supportive nutrition and hydration
Management of Odontogenic Infection
- Removal of the infection cause
- Incision and drainage (I&D) to remove pus
- Supportive therapy (antibiotics, anti-inflammatories, pain relief).
Removal of the cause
- Teeth restoration with root canal therapy or extraction to eliminate the infection cause.
- Curettage is performed to remove diseased tissues.
Incision and Drainage
- Minor surgical procedure to drain pus or fluid buildup under skin or mucous membranes.
Principles of Incision and Drainage
- In healthy tissue (away from the infected area)
- Esthetically pleasing, if possible
- Avoidance of injury to the nerves
- Involve only the superficial soft tissues
- Pus evacuation
- Daily wound cleaning
- Laboratory testing for antibiotic sensitivity
Methods of Drainage
- Root canal socket
- Extracted socket
- Bone fenestration
- Incision/surgical technique
Purpose of Drain
- Maintain incision patency/openness
- Allows pus discharge.
- Facilitates irrigation (cleaning)
Types of Drains
- Corrugated drains
- Penrose drains
- Vacuum drains
- Gauze pads
Medications
- Hydration
- Soft diet
- Analgesics
- Antibiotics
Guiding Principles for Antibiotic Use
- Identify the causative organism (bacteria)
- Antibiotic sensitivity testing
- Selecting least-toxic effective antibiotic
- Choosing bacteriocidal over bacteriostatic antibiotics
- Considering the cost of antibiotic choices
- Proper dosage and duration for optimal effect.
Indications for Combination Antibiotic Therapy
- High virulence of the microorganism and widespread infection
- Risk of developing bacterial resistance
- Achieving bactericidal effect
- Increased antibiotic spectrum
Causes of Antibiotic Therapy Failure
- Incorrect antibiotic type
- Inadequate dose or duration
- Reduced patient immunity
- Presence of foreign objects
- Unsatisfactory surgical management
Fatal (Life-Threatening) Conditions
- Ludwig's angina is a life-threatening complication from odontogenic infections.
- Reasons include (1) severe dental infection (90%), (2) fractured mandible, (3) submandibular gland infection, or (4) oral piercing injuries.
