Description

Flint et al reported the Extent, Location, Severity (ELS) Oral Mucosal Lesion Quantification System. This can be used to evaluate patients with oral lesions. The authors are from multiple hospitals and universities in England, Ireland and the United States and were participants at a workshop on oral and mucosal lesions of HIV/AIDS.

Locations:

(1) buccal or labial mucosa (B)

(3) gingival (G)

(4) hard palate (H)
