 Lesion restricted to the region of the tooth

Example

Example

Periodontal lesions & pericoronitis

 Lesion extended into overlying soft tissues

 Arises in the tissues surrounding the crown of the PE tooth

Periapical inflammatory lesions

 Acute apical periodontitis

 Chronic apical periodontitis

 Periapical abscess

 Periapical granuloma

Periapical inflammatory lesions

Rarefying oseitis/sclerosing osteitis

Caries acute Necrotic pulp apical periodontitis Trauma chronic

Periapical abcess

facial swelling, fever, lymphadenopathy

Radiographic features

 Periphery

 Ill defined

 Well defined

Radiographic features

 Internal structure

 Early …..no changes

 Loss of bone density (widening of PDL at apex)

 Larger diameter involvement

 Mixture of sclerosis and rarefaction
