Summary
Severe cervical root resorption linked to an acid-enriched diet and periodontal pathogens resolved with treatment. This case highlights the potential for root repair following intervention for dental issues.
Area of Science:
- Dentistry and Oral Pathology
- Periodontology
- Dietary Science
Background:
- Generalized cervical root resorption etiology remains unclear.
- Presents a severe case involving 24 teeth, developing after adopting an acid-enriched diet.
- Associated with gingival inflammation and crestal bone resorption, but not generalized attachment loss.
Observation:
- Subgingival plaque analysis identified periodontal pathogens, including Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis.
- Lesions extended into coronal dentin.
- Treatment involved mechanical debridement, antibiotics (amoxicillin plus metronidazole), and dietary modifications.
Findings:
- Complete repair of resorptive lesions occurred within 1 year, evidenced by radio-opaque mineralized tissue ingrowth.
- Radiological evidence of bone repair in crestal areas was observed.
- Histological examination of an extracted premolar revealed woven bone-like tissue invasion into resorbed dentin.
Implications:
- Suggests cervical resorptions may stem from osteoclastic activity due to compromised junctional epithelium protection.
- Hypothesizes a combined influence of periodontopathogenic bacteria and dietary factors.
- Demonstrates the potential for root and bone repair with comprehensive treatment, including dietary counseling.
