Asymptomatic condition that is discovered on routine radiography

Etiology: It is possibly derived from the PDL

Epidemiology: Poorly understood predilection for black female patients, 5th and 6th decades

Clinical:

• Lower anterior region
• Associated teeth usually – vital pulps
• Common complication: Osteomyelitis after extractions – due to poor vascularity of bone

Clinical subtypes:

• Single (< 1.5 cm diameter)
• Multiple
• Florid (familial tendency)

Radiology:

• Early – Circumscribed radiolucencies involving apical area of anterior teeth.
• Late – Mixed radiolucency to ”cotton wool” appearance

Histology: Trabecular/sclerotic areas of lamellar bone OR cementum-like material interspersed in fibrous matrix

Management: Surgical curettage with care, the lesions does not separate clearly from bone
