Изменение свойств поверхности зуба при воздействии холодной атмосферной плазмой

The article presents the results of experimental studies of the wetting angle of the tooth surface after treatment in the plasma of a dielectric barrier discharge at atmospheric pressure. Measurements of the dependence of the length of the plasma torch and the temperature of the treatment object on the flow rate of the working gas have been carried out. Argon was used as a working gas. The research revealed the possibility to change the length of the plasma torch in the range from 9 mm to more than 25 mm and showed that the temperature of the treated tooth surface with an increase in flow rate from 40 degrees Celsius falls to 32 degrees Celsius. The distilled water wetting angle was determined by the lying drop method. Depending on the processing time, a decrease in the contact angle of the tooth surface wetting from the initial 77 to 20 degrees was observed. The modes of operation of the plasma generator in tooth surface treatment, which provide the best indicators of its wettability, have been determined.В статье излагаются результаты экспериментальных исследований угла смачиваемости поверхности зуба после обработки в плазме диэлектрического барьерного разряда при атмосферном давлении. Проведены измерения зависимости длины плазменного факела и температуры объекта обработки от расхода рабочего газа. В качестве рабочего газа использовался аргон. В результате проведения исследований установлено, что можно изменять длину плазменного факела в диапазоне от 9 мм до более 25 мм, а температура обрабатываемой поверхности зуба при повышении расхода от 40 град. Цельсия падала до 32 град. Цельсия. Угол смачивания дистиллированной водой определялся методом лежащей капли. В зависимости от времени обработки наблюдалось снижение краевого угла смачивания поверхности зуба от исходных 77 до 20 град. Определены режимы работы генератора плазмы в процессе обработки поверхности зуба, обеспечивающие наилучшие показатели ее смачиваемости
