Large oral ulcer of tongue related to dental trauma.

ABSTRACT

A 36-year-old Philippine male has a several month-history of burning pain of his tongue with lingual erythema and oral bleeding. Here we describe a classical case of oral chronic ulcer related to mechanical dental trauma. In this case, unilateral crossbite malocclusion was able to produce oral mucosal lesion that was sufficient to cause a large, chronic tongue ulcer and subsequent mild epithelial dysplasia. A specific tongue-retaining device was made. In absence of dental trauma, his chronic ulcer of the tongue resolved within a few weeks. This case suggests evidence on the direct relationship between chronic oral trauma and the potential occurrence of a dysplastic process.
