The earliest and most frequent complication after radiation therapy of squamous cell cancer of the oropharyngeal region is oral mucositis. This study aims to assess dental status in patients with squamous cell cancer of the oropharyngeal region before and after radiation therapy. The study was conducted in the examination of 69 patients with verified squamous cell cancer of the oropharyngeal region. Before and after radiation therapy, we evaluated the oral cavity with indices: prevalence and intensity of caries, individual hygiene index (Green V.), gums inflammation intensity index (PMA), periodontal disease prevalence index (CPITN). After the end of radiation therapy, oral mucositis was recorded in all patients. In the course of the study, we found a significant deterioration of the oral cavity for all indicators, especially the PMA index, gingivitis increased by 16.1% (p < 0.05). The development of oral mucositis in both the early and late postray period leads to physical suffering, and a decline in the patient 's quality of life. An important point in the prevention of oral mucositis is the early sanitization of the oral cavity and the training of the patient in the correct hygienic skills.
