Summary
Radiation therapy did not alter the hardness of enamel or dentin in impacted third molars. This study examined the effects of irradiation on tooth structure after surgical removal.
Area of Science:
- Dental Science
- Radiation Oncology
Context:
- Impacted third molars are common dental issues.
- Surgical extraction is a standard treatment.
- Understanding radiation effects on dental tissues is crucial for patients undergoing radiotherapy.
Purpose:
- To investigate the impact of varying doses of irradiation on the hardness of enamel and dentin.
- To determine if radiation exposure affects the structural integrity of human teeth.
Summary:
- Fifty impacted third molars were surgically extracted and bisected.
- One half of each tooth was subjected to irradiation at 60 Gy or 120 Gy.
- Analysis revealed no significant changes in enamel or dentin hardness post-irradiation.
Impact:
- Provides data on the radiobiological effects on dental hard tissues.
- Informs dental professionals about potential outcomes for patients receiving radiation therapy.
- Contributes to the understanding of radiation's interaction with tooth structure.
