What is the primary cause of ulcerative stomatitis?

• A. Viral infection
• B. IgG against basal layer
• C. Bacterial infection
• D. Fungal infection

Answer: (B)

Ulcerative stomatitis is primarily associated with an autoimmune process, where the body produces IgG antibodies against components of the basal layer of the oral mucosa, leading to tissue damage and ulceration. This condition reflects a breakdown in the immunological tolerance to self-antigens, which can result in the formation of ulcers within the oral cavity. The antibodies target epithelial components, disrupting the integrity of the mucosal tissues, ultimately manifesting as painful sores and ulcers. While viral, bacterial, and fungal infections can lead to various forms of stomatitis, their mechanisms differ significantly from the autoimmune etiology characterized by IgG production against the basal layer. Understanding this distinction is important in recognizing that ulcerative stomatitis, in this context, arises predominantly from an immune dysregulation rather than infectious agents.
