Оценка качества индивидуальной гигиены полости рта пациентов с плоскоклеточным раком орофарингеальной области до и после лучевой терапии.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Были обследованы 76 пациентов с плоскоклеточным раком орофарингеальной  области. У всех пациентов до начала лучевой терапии и после ее завершения оценивали гигиеническое  состояние ротовой полости с помощью индексов: индекс индивидуальной гигиены (Green V.), десневой индекс Silness-Loe (GI), индекс распространенности болезней пародонта (CPITN).</p></sec><sec><title>Результаты</title><p>Результаты. Количество мужчин было больше по сравнению с лицами женского пола: 52 (68,4%) против 24 (31,6%). До начала лучевой терапии у 52 (68,4%) пациентов был выявлен гингивит, у 66 (86,8%) человек — пародонтит, у 43 (56,5%) — наличие металлических коронок, у 57 (76%) — наличие разрушенных зубов. После окончания лучевой терапии у всех пациентов (100%) был зафиксирован оральный мукозит. Мы выявили достоверную отрицательную динамику: индекс Green V. изменился на 29,2%, показатели CPITN — на 38%, GI — на 31,2% (p&lt;0,05). Также была зафиксирована прямая зависимость степени тяжести орального  мукозита от суммарной дозы облучения. Так, при суммарной дозе облучения 30 Гр и выше у пациентов со  злокачественными новообразованиями (ЗНО) полости рта развивается оральный мукозит тяжелой степени. При суммарной дозе облучения 40 Гр и выше вероятность появления орального мукозита 4 степени тяжести возможна в 2/3 случаев.</p></sec><sec><title>Заключение</title><p>Заключение. Степень тяжести орального мукозита зависит и от суммарной дозы облучения, и от исходного стоматологического статуса пациента. Поэтому контроль качества индивидуальной гигиены полости рта и пародонтологическое сопровождение пациентов с ЗНО полости рта должны проводиться на протяжениивсего лечения пациента.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. Assessment of the quality of individual oral hygiene in patients with squamous cell oropharyngeal cancer before and after radiation therapy.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Examined 76 patients with squamous cell carcinoma of the oropharyngeal region. For all patients, before and after radiation therapy, evaluated the hygienic state of the oral cavity using indices: index of individual hygiene (Green V.), Silness‑Loe index (GI), index of prevalence of periodontal diseases (CPITN).</p></sec><sec><title>Results</title><p>Results. The number of males was higher than that of females: 52 (68.4%) versus 24 (31.6%). Before radiotherapy, 52 (68.4%) patients had gingivitis, 66 (86.8%) had periodontitis, 43 (56.5%) had metal crowns, and 57 (76%) had destroyed teeth. All patients (100%) had oral mucositis after radiation therapy. We found a significant negative trend: the Green V. index changed by 29.2%, CPITN indicators‑by 38%, GI — by 31.2% (p&lt;0.05). There was also a direct dependence of the severity of oral mucositis on the total dose of radiation. Thus, patients with squamous cell carcinoma of the oropharyngeal region develop severe oral mucositis with a total radiation dose of 30 Gy and above. The probability of occurrence of oral mucositis of 4 severity is possible in 2/3 cases with a total radiation dose of 40 Gy or higher.</p></sec><sec><title>Conclusion</title><p>Conclusion. The severity of oral mucositis depends on both the total radiation dose and the initial dental status of the patient. Therefore, quality control of individual oral hygiene and periodontal support for patients with oral malignancies should be carried out throughout the patient's treatment. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак головы и шеи</kwd><kwd>плоскоклеточный рак орофарингеальной области</kwd><kwd>оральный мукозит</kwd><kwd>индекс индивидуальной гигиены ротовой полости</kwd><kwd>индекс распространенности болезней пародонта</kwd><kwd>лучевая терапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>head and neck cancer</kwd><kwd>squamous cell carcinoma of the oropharyngeal region</kwd><kwd>oral mucositis</kwd><kwd>index of individual oral hygiene</kwd><kwd>index of prevalence of periodontal diseases</kwd><kwd>radiation therapy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Idris S, Baqays A, Isaac A, Chau JKM, Calhoun KH, Seikaly H.
