The document discusses various types of lesions affecting the dental pulp and periodontium, such as primary endodontic lesions, primary periodontal lesions, and true combined lesions, along with their management and prognosis. Treatment approaches involve either endodontic therapy or surgical periodontics depending on the lesion type, with healing outcomes varying from good to fair-poor. It highlights the importance of adequate periodontal management in the prognosis of combined lesions.

No. Lesion Origin Management
1. Primary Endodontic
Lesions
Pulp Usually heal after a correct endodontic treatment.
Prognosis : Good
2. Primary Periodontal
Lesions
Periodontium Eliminating all Etiologic factors which can induce or
promote epithelial downgrowth followed by surgical
periodontics.
Prognosis : Good
3. True Combined
Lesions
BOTH
Pulp
&
Periodontium
True combined lesions should be addressed with an
endodontic treatment.
Before any periodontal surgical procedure, etiologic
therapy should be initiated as the prognostic of these
combined lesions is closely related to the efficiency of the
periodontal management.
Prognosis : Fair - Poor
