Материал и методы. В исследовании участвовало 30 крыс линии Вистар, которым после моделирования пародонтита с использованием «лигатурной» методики проводили лазерную терапию с использованием квазинепрерывного лазерного излучения с длиной волны 1265 нм с различной мощностью и экспозицией. Результаты лечения оценивали на 7-е сутки после начала лечения по объективным признакам состояния тканей в полости рта животных и с помощью морфологического исследования, в котором оценивали состояние тканей периодонта, наличие реактивного воспаления, наличие фрагментов некроза альвеолярной кости. Результаты. Осмотр в полости рта животных показал наилучшие результаты терапии в группах с параметрами излучения 1,6 Вт – 300 с и 1,8 Вт – 180 с. При этом морфологический анализ в данных группах также определил наилучший результат. Заключение. Оптимальными и эффективными терапевтическими режимами являются средняя мощность излучения 1,6 Вт в течение 300 с (480 Дж) и 1,8 Вт в течение 180 с (324 Дж).</p></abstract><trans-abstract xml:lang="en"><p>Purpose. To determine optimal power and exposure characteristics of laser procedures with 1265 nm laser light for treating periodontal diseases in experiment. Materials and methods. 30 Wistar rats were taken into the study. After modeling periodontitis in these animals with the ligature technique, they had laser treatment with 1265 nm quasi-continuous laser light using various power and exposure parameters. The effectiveness of the discussed therapy was assessed on day 7 after the trial beginning. The following objective parameters were analyzed: state of tissues in the oral cavity; morphological picture in periodontal tissues, presence of reactive inflammation and necrotic fragments in the alveolar bone. Results. The obtained findings has demonstrated that the best results were seen in the groups of animals where irradiation parameters were 1.6 W – 300 s and 1.8 W – 180 s. Similarly, morphological picture was also the best in these groups. Conclusion. The most effective and optimal therapeutic regimes are: average power 1.6 W for 300 s (480 J) and 1.8 W for 180 s (324 J).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пародонтит</kwd><kwd>лазеротерапия болезней пародонта</kwd><kwd>квазинепрерывное лазерное излучение 1265 нм.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>periodontitis</kwd><kwd>laser therapy of periodontal diseases</kwd><kwd>1265 nm quasi-continuous laser irradiation</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">Алексеев Ю.В., Иванов А.В., Миславский О.В. и др.
