Summary

External root resorption, often pathological, presents challenges in classification. Management focuses on monitoring and minimal intervention due to lack of curative treatments for this condition.

Area of Science:

Dentistry
Endodontics
Oral Pathology

Background:

Root resorption in permanent teeth is typically pathological, with local factors like pressure and inflammation being common causes.
Systemic conditions can also contribute to root resorption, which is often discovered incidentally during routine dental examinations.

Observation:

This report details two cases of external root resorption, emphasizing less common etiologies and classification complexities.
External apical root resorption, a rarer form, may be idiopathic or linked to systemic diseases, tumors, or cysts.

Findings:

No definitive causative factors were identified in most external apical root resorption cases.
Current management for external apical root resorption involves symptomatic treatment, minimal intervention, and long-term patient monitoring.

Endodontic treatment is generally not indicated unless pulpal or periapical disease is evident.

Implications:

Understanding rarer causes and classification difficulties is crucial for accurate diagnosis of external root resorption.
Long-term monitoring is essential for patients with external apical root resorption, given the absence of curative treatments.
This highlights the importance of comprehensive evaluation for potential systemic links in unexplained root resorption cases.
