Study Notes
Dr. Jafar Naghshbandi
- D.D.S; M.S, Diplomate of the American Board of Periodontology.
- Specialist in endodontics.
Key Quotes
- "Whoever taught me a word made me his servant."
- "Nobody cares how much you know until they know how much you care." – Theodore Roosevelt.
Dental Developments and Anatomy
- Developmental enamel projections can form grooves and pearls at the cervical portion of teeth.
- Accessory canals and lateral canals are present and connect with the apical foramen.
Tooth Fractures and Resorption Types
- Vertical tooth fractures can lead to idiopathic resorption.
- Resorption can occur from:
- Pulp to the surface of the tooth.
- External surface of the root to the pulp.
- Both internal and external sources create communication, risking cementum loss.
Endodontic Procedures and Risks
- Accidental lateral root perforation can occur during endodontic planning.
- Major causes of pulpal inflammation include:
- Instrumentation during procedures (periodontal, restorative).
- Progression of dental caries.
- Tooth fractures.
Atrophic Pulp Studies
- Bender and Seltzer (1972) found that atrophic pulps are more common in teeth with caries or restorations when periodontal disease is present.
- Disruption of blood flow through lateral canals leads to localized coagulation necrosis in the pulp.
Impact of Scaling Procedures
- Subgingival scaling and root planing may induce changes in the pulp, potentially severing blood vessels in lateral canals and causing pulpal necrosis.
Types of Dental Lesions
- Primary and secondary endodontic or periodontal lesions are categorized as:
- Primary endodontic lesion.
- Primary endodontic with secondary periodontal lesion.
- Primary periodontal lesion.
- Primary periodontal lesion with secondary endodontic involvement.
- True combined lesions.
Microbiological Implications
- Bacteria are crucial in the development of pulpal and periodontal diseases, with similarities noted between microbiological findings in root canals and advanced periodontal pockets.
- Notable bacteria include B. forsythus, P. gingivalis, and T. denticola.
Diagnostic Procedures
- Assess endodontic status with traditional aids:
- Radiographic analysis.
- Gutta percha tracing.
- Periodontal probing.
- Fiber optic illumination to check for fractures.
- Vitality tests and percussion tests.
- Limitations of vitality testing highlight its focus on neural response without fully reflecting pulpal health.
- Advanced diagnostic methods under research include Doppler devices, pulse oximetry, and magnetic resonance imaging.
Treatment Controversies and Recommendations
- Debate exists over the order of endodontic versus periodontal therapy in managing endo-perio lesions.
- Evidence suggests performing endodontic therapy first is advisable.
- Inflammation from pulp that extends to the periodontium can lead to ‘retrograde periodontitis’ affecting periodontal tissues.
- Communication pathways between pulp and periodontium may have:
- Developmental origins.
- Pathologic origins.
- Iatrogenic origins.
