LOPEZ LABADY, Jeaneth et al. Tissue tag of the labial frenum: Development anomaly or neoplastic lesion?. Acta odontol. venez [online]. 2006, vol.44, n.1, pp.28-30. ISSN 0001-6365.

Tissue tag of the labial frenum (TTLF) is a fragment of oral mucosa that arises from the labial superior frenum. Its cause and function are still unknown, however, it is considered an alteration of the normal oral anatomy. Although its nature, many dentists and medics confuse this entity with fibrous hyperplasias produced by trauma. The aims of this study were to determine the frequency of TTLF and the association to traumatic local factors. 185 people were examined after filling an oral medicine history and signed an informed consent. About 20% of the study population showed TTLF (36 people), however, the use of prostheses or orthodontic treatment could not be statistically associated. TTLF is a relatively frequent development anomaly that it is not cause by trauma, and it does not represent a reactional lesion or a neoplasia.
