Frequencies of position parameter.

Foramen	Present (%)	Literature data (%)
Superior	62	62*/63,3**
Inferior	13	38*/13,34**
Two foramina	23	22*/23,3**/27,1***

*From lingual foramina on the mandibular midline revisited: a macroanatomical study; Liang et al. [4].
**From cone beam computed tomography observations of the lingual foramina and their bony canals in the median region of the mandible; Babiuc et al. [14].
***From computed tomographic diagnosis and localization of bone canals in the mandibular interforaminal region for prevention of bleeding complications during implant surgery; Tepper et al. [15].
