title: [Gingiva damaged by ill-fitting scuba-diving mouthpiece].
abstract: A 46-year old man presented a hyperlasia of the marginal gingiva of a mandibular molar. The reason of the hyperlasia could be found after further anamnestic questions: irritation by pressure of an ill-fitting scuba-diving mouthpiece. The patient was sports-diver and instructor. After instructions to the patient and an expectative approach, the hyperplasia disappeared spontaneously within a few months, without any kind of  therapy.
