Torus palatinus. Report of two cases

Hyperostosis is defined as a benign neoformation of bone tissue, diffused or localized hypertrophy thereof. In the oral cavity can affect the lingual surface of the mandibular bone (torus mandibularis), the hard palate (torus palatinus) or presented as multiple exostosis [1]. The latin word torus means tumor or circular protrusion and is not considered as a pathological condition, but an anatomical variation. The term torus is introduced by Kupfer and Besselhagen in 1879, and is used to designate the exostosis arising on the midline of the palate and the back and inside of the jaw [2].
