A new protocol for dental extractions in patients who received radiation therapy significantly reduces the risk of osteoradionecrosis. This method combines atraumatic surgery with a special alveolar sealant, improving healing outcomes in radiated bone.

Area of Science:

  • Oral surgery
  • Radiation oncology
  • Biomaterials

Context:

  • Dental extractions following radiation therapy pose a high risk of osteoradionecrosis.
  • Osteoradionecrosis (ORN) has a severe prognosis and can lead to complications.
  • Existing protocols for post-radiation dental extractions require optimization to improve healing.

Purpose:

  • To propose and evaluate a novel protocol for dental extractions in patients previously treated with radiation therapy.
  • To assess the efficacy of a specific surgical and sealant approach in preventing osteoradionecrosis.
  • To determine the rate of healing failure and osteoradionecrosis after implementing the proposed protocol.

Summary:

  • A protocol involving non-traumatic dental extractions and the use of a gentamicin-impregnated collagenic sealant was applied to 107 patients (287 extractions).

Related Experiment Videos

  • Extractions were performed under various anesthesia types, with antibiotic prophylaxis and wound closure using the sealant.
  • The study observed a very low rate of post-extraction osteoradionecrosis (0.35%), with only two cases of healing failure.

    • Impact:

    • The proposed protocol significantly decreases the risk of osteoradionecrosis after dental extractions in radiated bone.
    • This approach offers a safer alternative for patients requiring dental extractions post-radiation therapy.
    • Improved healing outcomes can enhance the quality of life for cancer survivors undergoing radiation treatment.
