Clinical Features of Cementoma

• It occurs most frequently under the age of 25 years.
• Mandible is affected more commonly than maxilla.
• Mandibular fist molar is most commonly affected tooth.
• It produces a slow enlarging bony hard swelling of jaw which causes expansion of jaw and displacement of regional teeth.
• Expansion of buccal and lingual cortical plates.
• Low-grade intermittent pain is present which felt more when area is palpated.
• A dull sound is produced when tooth is percussed.

Histopathology of Cementoma

• It presents a large mass of amorphous cemental tissue which shows the presence of multiple reversal line.
• Intervening connective tissue stroma contains many cementoblasts and cementoblasts cells.
• PDL adjacent to normal cementum becomes integrated with capsule and separate the neoplasm from surrounding bone.
• Multinucleated cells are present in the large number in central area and are associated with active resorption.
• Root of the involved tooth extends up to the center of lesion and neoplastic cemental tissue is continuous with normal cemental layer.

Treatment of Cementoma

Surgical excision is done.
