The torus palatinus is a slowly growing, flat-based bony protuberance which occurs in the midline of the hard palate. Numerous theories have been suggesed, but a plausible and thoroughly convincing explanation for his common oral lesion is still lacking. A study by Suzuki and Sakai offered evidence that both the torus palatinus and torus mandibularis are hereditary conditions, thougt to follow a mendelian dominant pattern.
The torus palatinus presents itself as an outgrowth in the midline of the palate and may assume a variety of shapes. It has been classified clinically on this basis as flat, spindle shaped, nodular or lobular. The mucosa overlying the torus is intact but occasionally appears blanched. It may become ulcerated if traumatized. The torus itself may be composed of either dense compact bone or of a shell of compact bone with a center of cancellous bone and thus it is often visible on a dental radiograph.
There is little clinical significance attached to this lesion, since it is benign and NEVER becomes malignant. The torus is usually not treated, although occasionally it may be of such size and shape that it is impossible to construct a full or partial denture over the torus because of undercuts, the probability of trauma to the overlying mucosa or inability to seat the denture owing to rocking. In such cases the situation must be appraised and the torus removed surgically before the construction of the prosthetic appliance.
