Oral slough caused by dentifrice detergents and aggravated by drugs with antisialic activity

A unusual type of oral desquamation appeared as grayish-white gelatinous membranes on the floor of the mouth, lips, vestibules, and gingiva in a 50-year-old woman. The painless desquamation was caused by synthetic dentifrice detergents (foaming agents) and was exacerbated by the patient's use of drugs with antisialic action.
