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)
- Caused by Mycobacterium tuberculosis, often a re-emerging disease.
- Oral lesions typically present as deep, painful ulcers with raised borders that gradually increase in size. Common site of oral TB is dorsum of the tongue.
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.
