Purpose:

Evaluate clinically the periodontal healing of root fracture treatment using adhesive resin cement.

Materials/Methods:

  • N= 23 teeth with vertical root fractures
  • 11 fractured roots were bonded through the root canal (group A). Root canal was filled with 4-META/MMA-TBB resin. Cast-post was inserted and held until bonded in tooth
  • 12 fractured roots were bonded extra-orally and replanted (group B)
  • All teeth were then restored with full cast crowns (n=20) or coping (n=3)
  • Patients were recalled at intervals of 2-6 months

Results:

1.Group A: After 6 months, 1 tooth extracted due to deep periodontal pocket, deterioration of bone defect and discomfort. Another tooth was extracted due to refracture after 11 months. The remaining teeth presented no discomfort and there was no deterioration of periodontal conditions over a mean period of 33 months (range 14–74 months). There were no ankylosed teeth or root resorption.

2.Group B:After 6 months, 1 tooth extracted due to deep periodontal pocket and increased mobility. Two more teeth were extracted due to refracture after 28 and 29 months. The rest of the teeth presented no discomfort to the patients and no deterioration of periodontal conditions was detected over a mean period of 22 months (5–48 months). There were no ankylosed teeth or root resorption.

Clinical Significance:

These case reports suggested that sealing the fracture and preventing the refracture might be a successful treatment modality for vertical root fracture.
