Hypercementosis is an idiopathic, non-neoplastic condition characterized by the excessive buildup of normal cementum (calcified tissue) on the roots of one or more teeth.〔 〕 A thicker layer of cementum can give the tooth an enlarged appearance, which mainly occurs at the apex or apices of the tooth. ==Etiology== Can be caused by many things. A way to remember the causes is "PIG ON TAP" Local factors- * Occlusal Trauma * Trauma * Non-functional tooth * Unopposed tooth (and impacted teeth, embedded teeth, teeth without antagonists) Systematic factors- * Idiopathic * Pituitary Gigantism * Paget's Disease * Acromegaly * Periapical granuloma * Arthritis * Calcinosis * Rheumatic fever It may be one of the complications of Paget's disease of bone in the form of generalized hypercementosis. It may also be a compensatory mechanism in response to attrition to increase occlusal tooth height. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hypercementosis」の詳細全文を読む スポンサード リンク
