Cementoma is an odontogenic tumor of cementum. It is usually observed as a benign spherical mass of hard tissue fused to the root of a tooth.[1] It is found most commonly in the mandible in the region of the lower molar teeth, occurring between the ages of 8 to 30 in both sexes with equal frequency .[1] It causes distortion of surrounding areas but is usually a painless growth, at least initially. Considerable thickening of the cementum can often be observed.
