Study Notes
White Lesions
- Burns can cause white lesions in the oral mucosa
- Chemical burns, thermal burns, and electrical burns can cause mucosal lesions
Chemical Injuries of the Oral Mucosa
- Can cause white lesions in the oral mucosa
- Uremic stomatitis is a type of chemical injury
Burns
- Depending on the magnitude and duration of the insult, the mucosal lesion can appear as:
- Localized erythema
- White necrotic slough that can be rubbed off, leaving a raw, red, bleeding, and painful surface
- Diagnosis is made by history
Acute Necrotizing Ulcerative Gingivostomatitis (ANUG)
- Can cause white lesions in the oral mucosa
Oral Candidiasis
- Candida species are normal inhabitants of oral flora in 40% - 60% of the population at low concentration
- Candida is an opportunistic infectious agent that is poorly equipped to invade and destroy tissue
- Predisposing factors for oral candidiasis include:
- Diabetes
- Malnutrition
- Immunosuppression
- Antibiotic therapy
- Hormonal imbalance
- Poor oral hygiene
Classification of Oral Candidiasis
- The disease can be either acute or chronic in nature
- Acute forms include:
- Acute Pseudomembranous Candidiasis (Thrush)
- Acute Atrophic Candidiasis (Antibiotic Stomatitis)
- Chronic forms include:
- Chronic Atrophic Candidiasis
- Denture Sore Mouth
This quiz covers the causes and effects of burns and white lesions on the oral mucosa, including chemical and thermal burns, and their diagnosis.
