Flashcards

Periapical Abscess

Occurs when the infection of the root canal system spreads to the tissues at the tip of the root. Characterized by pain, swelling, and potential systemic symptoms.

Osteomyelitis of the Jaw

A specific type of oral infection caused by bacteria like Fusobacterium, Prevotella, and Peptostreptococcus. It involves the bone surrounding the teeth, often due to untreated tooth infections.

Ludwig's Angina

A serious infection affecting the submandibular space, often stemming from dental problems. It's typically caused by a mix of bacteria including Streptococcus, Staphylococcus, and anaerobes.

Acute Necrotizing Ulcerative Gingivitis (ANUG)

A common infection of the gums characterized by painful, ulcerated areas with a gray pseudomembrane. It's often triggered by poor oral hygiene, stress, smoking, or weakened immune systems.

Study Notes

Oral Infections: Viral, Bacterial, & Fungal

  • Oral infections range from mild to severe, affecting both oral and systemic health.
  • Bacterial infections can present as localized lesions or widespread infections, leading to stomatitis, glossitis, gingivitis, and pharyngitis.
  • Bacterial infections in the oral cavity vary in severity depending on the specific bacteria, initial site, and patient's condition

Dental Caries

  • Causative bacteria: Streptococcus mutans, Lactobacillus species, Actinomyces.
  • Pathogenesis: These bacteria metabolize sugars, producing acid that demineralizes tooth enamel.
  • Symptoms: Tooth sensitivity, pain, visible cavities.
  • Prevention/treatment: Good oral hygiene, fluoride use, and fillings for advanced decay.

Periodontal Diseases

  • Gingivitis:
    • Pathogens: Porphyromonas gingivalis, Fusobacterium nucleatum, Prevotella intermedia.
    • Clinical features: Red, swollen gums that bleed on probing.
    • Management: Scaling and root planing, oral hygiene.
  • Periodontitis:
    • Pathogens: Similar to gingivitis, but with higher involvement of Aggregatibacter actinomycetemcomitans.
    • Clinical features: Pocket formation, bone loss, tooth mobility.
    • Management: Deep cleaning, possible surgery, antimicrobial therapy.
  • Periapical Abscess:
    • Pathogens: Mixed anaerobic bacteria (Fusobacterium, Prevotella, Peptostreptococcus).
    • Pathogenesis: Infection of the root canal system spreading to periapical tissues.
    • Clinical features: Pain, swelling, systemic symptoms if severe.
    • Management: Root canal therapy or extraction.

Acute Necrotizing Ulcerative Gingivitis (ANUG)

  • Pathogens: Treponema spp., Fusobacterium spp.
  • Pathogenesis: Poor oral hygiene, stress, smoking, immunosuppression.
  • Clinical features: Ulcerated, painful gums with gray pseudomembrane, halitosis.
  • Management: Debridement, antimicrobial therapy (e.g., metronidazole).

Osteomyelitis of the Jaw

  • Pathogens: Mixed anaerobic bacteria (Fusobacterium, Prevotella, Peptostreptococcus).
  • Pathogenesis: Infection of the root canal system spreading to periapical tissues.
  • Clinical features: Pain, swelling, systemic symptoms if severe.
  • Management: Root canal therapy or extraction.

Ludwig's Angina

  • Pathogens: Polymicrobial, including Streptococcus, Staphylococcus, and anaerobes.
  • Pathogenesis: Submandibular space infection, often secondary to dental infections.
  • Clinical features: Swelling, airway compromise..
  • Management: Airway management, IV antibiotics, surgical drainage.

Diagnosis

  • Clinical examination
  • Radiographic imaging (e.g., periapical, panoramic X-rays)
  • Microbial culture and sensitivity testing (in severe cases)

Prevention & Control

  • Regular oral hygiene
  • Routine dental check-ups
  • Prophylactic antibiotics (for high-risk patients, e.g., heart valve replacements)

Systemic Implications

  • Oral infections can cause bacteremia and spread to other parts of the body.
  • Systemic consequences include cardiovascular disease, diabetes, and adverse pregnancy outcomes..

Scarlet Fever

  • Caused by Streptococcus pyogenes (Group A Streptococcus, GAS).
  • Affects children aged 4–8 years, characterized by a distinctive rash, fever, general malaise, and sore throat
  • Pathophysiology involves the interaction of streptococcal erythrogenic toxin with the host immune system.

Clinical Features of Scarlet Fever

  • Prodromal Symptoms: Fever, chills, sore throat, headache, nausea, and vomiting.
  • Rash: Appears 12–48 hours after fever onset; diffuse, finely papular, "sandpaper-like" texture, accentuated in skin folds (Pastia's lines).
  • Tongue Changes: Initially coated with white, then progresses to bright red appearance ("strawberry tongue").
  • Desquamation: Peeling occurs after rash subsides, particularly on fingertips, palms, and soles.
  • Other features: Pharyngeal erythema, tonsillar exudates, and cervical lymphadenopathy.

Treatment of Scarlet Fever

  • Antibiotics: Penicillin V or amoxicillin (first-line treatment). Alternatives are macrolides (e.g., erythromycin) for penicillin-allergic patients.
  • Symptomatic relief: Antipyretics (e.g., acetaminophen) for fever, hydration, and soft foods for sore throat.
  • Complications (untreated): Acute rheumatic fever (ARF), post-streptococcal glomerulonephritis (PSGN), otitis media, pneumonia, or abscess formation.

Tuberculosis (TB)

Syphilis

  • Sexually transmitted disease caused by Treponema pallidum.
  • Stages include primary (chancre), secondary (rash), and tertiary (gummas). Oral lesions can occur in any stage but are often not the primary infection site.

Gonorrhoea

  • Sexually transmitted disease caused by Neisseria gonorrhoeae.
  • Often presents as a non-specific stomatitis or pharyngitis.
  • Treatment involves high-dose penicillin.

Glossitis

  • Inflammation of the tongue, characterized by changes in color, texture, and size. Can be acute or chronic, often associated with other conditions.

Mucositis

  • Inflammation of mucous membranes in the mouth and GI tract.
  • Common side effect of cancer treatments (chemotherapy and radiotherapy), infections, trauma.

Etiology of Glossitis, Mucositis

  • Nutritional Deficiencies: Iron, Vitamin B12, Folate
  • Infections: Bacterial (Syphilis), Fungal (Candidiasis), Viral (HSV)
  • Trauma/Irritation: Sharp teeth, dental appliances, hot/spicy food
  • Allergies: Dental products, foods
  • Systemic Conditions: Autoimmune (Sjögren’s), Anemias
  • Drug-Induced: Chemotherapy, antibiotics
  • Idiopathic Conditions: Geographic tongue, Median rhomboid glossitis

Management of Glossitis and Mucositis

  • Address Underlying Cause: Correct nutritional deficiencies, treat infections, manage allergies, or underlying conditions
  • Symptomatic Relief: Topical anesthetics, antiseptic rinses, dietary modifications.
  • General Measures: Maintain good oral hygiene, use soft toothbrushes, regular dental checkups
  • Treatment of chronic conditions: Biopsy for malignancy or precancerous conditions.
