In 1817, the denominated conduct of Serres was described as a formation that was highly prevalent in children's jaws, but considered as an anatomical variation in adults. In this study we analyze the presence of the denominated Serres'- conduct in 324 jaws belonging to the collection of the Universidade Federal de Sao Paulo (UNIFESP), with sex and age registration, 68 subadults of age between 0 and 2 years and 256 adults of age between 18 and 100 years. We found that the prevalence was in order to 100% in the subadults group and 42.6% in the adults group. In adults, the prevalence of this anatomical structure was greater in women than in men, with a difference statistically significant for the variable sex (Chi2 = 0.0148; I. C 95%=0.29-0.91; O.R. = 0.51). According to the age, the biggest prevalence was in the fourth decade of the life, not being of any statistical significance for this variable. Based on the opposing evidence, this article discusses the character of anatomical variation of this formation and based on the anatomical terminology, intending to denominate the paramandibular canal.
