Dental root resorption
1Department of Endodontics, Howard University College of Dentistry, Washington, DC, USA.
Summary
This review examines physiologic mechanisms of root resorption, including surface, inflammatory, and replacement types. It discusses traumatic injuries, periradicular pathosis, and pressure-induced resorption, offering insights into etiology and treatment.
Area of Science:
- Dental Physiology
- Periodontal Ligament Biology
- Root Resorption Mechanisms
Background:
- Root resorption is a complex clinical phenomenon.
- Understanding homeostatic mechanisms of the periodontal ligament is crucial.
- The role of intermediate cementum in preventing resorption requires clarification.
Purpose of the Study:
- To review the physiologic mechanisms underlying various clinical root resorption types.
- To discuss root resorption associated with traumatic dental injuries.
- To explore other resorption classifications, including internal, cervical, and external types.
Main Methods:
- Literature review of existing research on root resorption.
- Analysis of physiologic and homeostatic mechanisms.
- Classification and discussion of resorption based on etiology and clinical presentation.
Main Results:
- Detailed examination of surface, inflammatory, and replacement root resorption.
- Etiology and treatment considerations for trauma-induced resorption.
- Overview of internal, cervical, and external resorption linked to periradicular pathosis and pressure.
Conclusions:
- Physiologic mechanisms govern diverse root resorption processes.
- Traumatic injuries and periradicular pathosis are significant etiological factors.
- Further understanding of these mechanisms can guide clinical management and treatment strategies.
