Study Notes

Perio-Endo Lesions Overview

Endodontic and periodontal diseases are polymicrobial anaerobic infections.
The term "endo-perio" lesion refers to inflammation affecting both pulpal and periodontal tissues.
Classification of perio-endo lesions is based on associated pulpal pathology and periodontal inflammation.

Intercommunication Between Pulpal and Periodontal Tissue

Several pathways enable disease interaction:
- Neural pathways and vascular structures.
- Lateral canals and dentinal tubules, particularly when cementum is exposed.
- Palatogingival grooves, especially in maxillary lateral incisors.
- Periodontal ligament and alveolar bone connections.
- Apical foramina serve as a direct communication route to periodontium.

Influence of Pulpal Pathologic Condition on Periodontium

Pulpal degeneration causes necrotic debris and irritants that can lead to periodontal destruction.
Factors affecting the extent of periodontal damage include:
- Virulence of root canal irritants (microbiota, foreign body responses).
- Duration of disease progression.
- Host defense mechanisms.

Influence of Periodontal Inflammation on the Pulp

Periodontitis can affect pulpal health through:
- Infection from periodontal pockets via dentinal tubules or accessory canals.
- Damage from periodontal treatments affecting cementum.
Pulp usually maintains vitality if the main canal is intact and blood supply is preserved.

Theoretical Pathways of Osseous Lesion Formation

Established connections between pulpal and periodontal diseases are supported by clinical and radiographic evaluations.
Critical assessments include medical history, pulp vitality tests, probing depths, and radiographs.
Treatment requires addressing both periodontal and pulpal conditions to enhance tooth retention.

Primary Endodontic Lesions

Typically arise from caries, restorative procedures, or trauma, leading to localized inflammatory changes.
Clinical findings include:
- Negative responses to cold tests.
- Pain and tenderness on palpation.
- Increased tooth mobility and swelling of marginal gingiva.
- Potential sinus tracts that trace to the apex or furcation areas.

Primary Endodontic Lesions with Secondary Periodontal Involvement

Occurs when untreated endodontic lesions progress to involve periodontal structures, leading to alveolar bone destruction.
Treatment involves addressing the endodontic issue first, followed by periodontal care.
Prognosis relies on the effectiveness of both treatments and the extent of periodontal damage.

Primary Periodontal Lesions

Characterized by progressive disease, often exacerbated by local factors such as poorly placed restorations or occlusal trauma.
Clinical findings feature:
- Vital response to cold tests.
- Increased tooth mobility and broad-based pocket formation.
- Generalized bony lesions compared to endodontic lesions.
Treatment varies based on the severity of periodontitis.

Primary Periodontal Lesions with Secondary Endodontic Involvement

Occurs when periodontal disease advances to create a connection with the pulp.
Differentiated from primary endodontic lesions; the disease sequence is pivotal in diagnosis and treatment planning.
