Summary
Head and neck radiotherapy significantly impacts oral health, causing xerostomia, mucositis, and dental caries. Early oral care interventions are crucial for managing these radiotherapy side effects.
Area of Science:
- Oncology
- Oral Medicine
- Radiotherapy
Background:
- Head and neck radiotherapy can lead to significant oral complications.
- Nasopharyngeal carcinoma patients undergoing radiotherapy are at risk for xerostomia, mucositis, and dental caries.
Purpose of the Study:
- To evaluate the incidence and severity of xerostomia, mucositis, and dental caries in patients undergoing head and neck radiotherapy.
- To assess the impact of radiotherapy dosage on oral health outcomes.
Main Methods:
- Twenty nasopharyngeal carcinoma patients were assessed before, during, and after radiotherapy.
- Oral examinations, salivary flow rate measurements (modified Schirmer's test), and dental caries evaluation were performed.
- Oral hygiene instructions and dental interventions were provided throughout the treatment period.
Main Results:
- Salivary flow rate decreased significantly with increasing radiotherapy dosage.
- Xerostomia and mucositis developed in parallel with reduced salivary flow and increased irradiation.
- Mucositis resolved within six months post-radiotherapy, but new carious lesions were detected in two patients.
Conclusions:
- Radiotherapy for head and neck cancer causes significant oral sequelae.
- Comprehensive oral health management, including instructions and interventions, is essential before, during, and after radiotherapy to mitigate adverse effects.
