The oral cavity is examined for the characteristic lesion of NUG, its distribution, and the possible involvement of the oropharyngeal region. Oral hygiene is evaluated, with special attention to the presence of pericoronal flaps, periodontal pockets, and local factors (e.g., poor restorations, distribution of calculus). Periodontal probing of NUG lesions is likely to be very painful and may need to be deferred until after the acute lesions are resolved.

The goals of initial therapy are to reduce the microbial load and remove necrotic tissue to the degree that repair and regeneration of normal tissue barriers are reestablished.
