Cementicles are mineralized structures that either freely reside in the periodontal ligament or adhere to the root surface. The presence of cementicles and ectopic enamel deposits on the root may compromise plaque and calculus removal. Epithelial rests of Malassez have been implicated in the formation of cementicles. True cementicles consisted of a collagenous matrix intermixed with a noncollagenous ground substance. BSP ( Bone sialoprotein) and OPN( osteopontin) was mainly associated with the interfibrillar ground substance.
