1. 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.

2. 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.

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