تستخدم الاهتزازات فوق الصوتية لنزع القلح و التصبغ و تجريف
الجيوب حول السنية كما تستخدم في سياق نزع التيجان الكاملة المعدنية و المعدنية
الخزفية و بالتالي فإن الرؤوس المستخدمة سواءً للتقليح أو للنزع تكون على تماس مباشر
مع هذه التيجان لذلك كان هدف الدراسة تقييم سطح التيجان المعدنية الخزفية بعد
تعرضها للاهتزازات فوق الصوتية.
Vibration of Ultrasonic has used for scaling
and periodontal curettage, it is also has used for metal crown and
metal-ceramic crown removal, subsequently, using the tips whether for
scaling or removing crown, they will be in direct contact with this crown,
This research aimed to evaluate the surface of metal-ceramic crown
after exposure to Vibration of Ultrasonic tips.
