Dental Care for Cancer Patients in the Prevention of Complications of Chemotherapy and Head and Neck Radiation Therapy

Oncological diseases occupy one of the first places in the structure of disability and mortality of the population. The main methods of treating patients with malignant tumors in the maxillofacial area are surgical method, radiation therapy and chemotherapy. Treatment with only one of the listed methods It is rarely performed, mainly at the stage of cancer in situ or stage I of the disease. The treatment depends on the clinical and morphological characteristics of the tumor and requires the use of all methods simultaneously or in a certain sequence. Radiation and chemotherapy treatments not only have systemic side effects, but also side effects in the treatment area. Against the background of antitumor treatment, there is an exacerbation of concomitant chronic diseases, including odontogenic ones. Pathological changes appear on the mucous membrane oral cavity, on the skin, in the subcutaneous tissue, in the salivary glands and in the bone marrow of the jaw bones. The degree of damage to these structures during tumor treatment depends on their initial condition. At the same time, the initial condition of the oral cavity affects the quality of antitumor treatment. Poor oral hygiene and chronic odontogenic lesions can cause the development of episodic fevers and other general complications. All this requires stopping or changes in the tactics of antitumor treatment, which reduces its radicalism. It becomes obvious that sanitation of the oral cavity, carried out before treatment by an oncologist, will avoid or reduce the frequency complications in the maxillofacial area, improve the quality of life of an oncology patient.
