There is a well-defined monolocular round shaped radiolucence without a corticated margin at the apical area of both mandibular central incisors(tooth 24,25)extending from the mesial aspect of tooth 26 to the periapical area of tooth 24,measuring

• There is a well-defined monolocular round shaped
  radiolucence without a corticated margin at the
  apical area of both mandibular central
  incisors(tooth 24,25)extending from the mesial
  aspect of tooth 26 to the periapical area of
  tooth 24,measuring approximately 1 cm in diameter
  .the adjacent teeth are typically vital and not
  resorbed with an intact periapical ligament
  space.

Cemetoma , periapical cemento-osseous dysplasia ,
stage 1

• Middle-aged adults (typically black women )
• Monolocular , often multiple
• Early stage radiolucent ,not corticated
• Intermediate stage radiopacity within the
  apical radiolucencies
• Late stage densely radiopaque but surrounded by
  a thin radiolucent line
• Traumatic ( solitary ) bone cyst
• Radicular cyst
• Periapical granuloma

3

• There is a continuous irregular radiolucence with
  a poor defined margin along the apical area of
  the right maxillary posterior teeth (tooth
  2,3,4and 5),and a well-defined round shaped
  radiolucence without a corticated margin at the
  periapical area of tooth 4 ,with a superior
  margin at the apex os the root and a inferior
  margin near the midle one-third of the
  root,measuring approximately 1 cm in
  diameter.Severe bone destruction can be observed
  around the roots of the teeth.

Periodontitis

• Localized severe bone destruction around the
  roots of the teeth
• Endo-perio lesion
• Eosinophilic granuloma
• Traumatic (solitary ) bone cyst
• Periapical granuloma
• Radicular cyst
