Which one of the following inflammatory disorders affecting the oral cavity is often determined as being psychogenic in origin?

Burning mouth syndrome is characterized by a persistent burning sensation in the oral cavity without an obvious cause, such as an identifiable lesion. It is often associated with psychological factors, making it psychogenic in origin. Many patients report symptoms that are exacerbated by stress and anxiety, and the condition can be linked to underlying psychological issues like depression or anxiety disorders.

The phenomenon of having a burning sensation without detectable oral pathology supports the idea that it is influenced by psychosocial factors. Consequently, effective management of burning mouth syndrome often includes addressing any psychological components through counseling or stress management techniques, in addition to considering medical treatments for symptoms.

Other conditions listed, such as angular cheilitis, erythroplakia, and hand, foot, and mouth disease, do not primarily have psychogenic origins. Angular cheilitis is typically associated with fungal infections or nutritional deficiencies. Erythroplakia is a potentially precancerous condition often linked to irritation or tobacco use, and hand, foot, and mouth disease is a viral infection, none of which are rooted in psychological factors. Thus, burning mouth syndrome stands out as the most relevant condition related to the psychogenic origin.
