Summary

Head and neck radiation therapy significantly impacts periodontal health, causing attachment loss, especially in the mandible. Regular periodontal evaluations are crucial for oncology patients undergoing such treatments.

Area of Science:

  • Oncology
  • Periodontology
  • Radiotherapy

Background:

  • Head and neck radiation therapy can affect oral health.
  • The periodontium is susceptible to radiation-induced changes.

Purpose of the Study:

  • To evaluate changes in the periodontium after head and neck radiation therapy.
  • To assess the impact of radiation on periodontal parameters.

Main Methods:

  • Assessed periodontal clinical parameters in 27 patients.
  • Evaluations were conducted before and 6-8 months post-radiation therapy.
  • Measured probing depth, clinical attachment level, gingival recession, plaque index, and bleeding on probing.

Main Results:

  • Significant changes observed in clinical attachment level (CAL).

  • 70.3% of patients experienced CAL loss, with 92% in the mandible.
  • Attachment loss correlated with radiation field, particularly when jaws were included.

    • Conclusions:

    • Periodontal status requires evaluation before and after radiation therapy.
    • Maintaining periodontal health is essential for oncology patients.
    • Oral-maxillary-facial region requires careful monitoring post-radiation.
