By noting if the mucosal alterations resolve when the drug is discontinued

What is the first step in treating a drug-related oral reaction?

Discontinue the responsible medication if possible

Where does perioral dermatitis typically appear?

Around the mouth, and may spread to the nose and eyes

What is an important step in managing acute localized mucositis?

Removal of the focal trauma, such as dental metals

How is acute stomatitis typically diagnosed?

Factors important in diagnosing a lichenoid contact reaction

The clinical characteristics of the lesion, lack of lesion migration, and correlation to adjacent dental metal.

Use of certain medications and exposure to allergens.

Salivary gland aplasia

It is a developmental anomaly and a rare occurrence.
