Elle and Elina

Lesions that affect the periodontium and pulp are classified by the sequence in the disease process.
 * __Periodontitis Associated with Endodontic Lesions __**

With these lesions the pulp of the tooth becomes necrotic before any periodontal changes occur. The lesion originates in the pulp. - What it would look like clinically: localized deep periodontal pocket and fucation involvement may be present due to loss of attachment and bone. - What it would look like radiographically: periapical abscess that appears as a circular radiolucent lesion on the apex of the root, loss of the lamina dura, destruction of the PDL, and localized bone loss. - How you would diagnosis it: radiographically Differential diagnosis: periapical cyst, lateral perio cyst, or periapical granuloma.
 * __Endo-perio lesion: __**

These types of lesions result from bacterial infection from a peio. pocket that can spread through the accessory canals to the pulp which will result in pulp necrosis. - What it would look like clinically: loss of attachment, root exposure, erythematous, inflammation when probing a deep pocket measurement will be noted. - What it would look like radiographically: fuzzy lamina dura, break in the PDL, radiolucencies around the roots, and intra-radicular radiolucencies may be present. - How you would diagnosis it: radiographically Differential diagnosis: periapical cyst or lateral perio cyst.
 * __Perio-endo lesion: __**



These result from development and extension of an endodontic lesion into an existing periodontal lesion. - What it would look like clinically: These lesions have combined characteristics of both of the above lesions. - What it would look like radiographically: advanced bone loss with intrabony defect, and possible intra-radicular radiolucencies. - How you would diagnosis it: Clinically, radiographically, and a thorough history to assess the cause of each lesion. Differential diagnosis: periapical cyst or lateral perio cyst.
