Dear Colleagues, I invite you to attend my seminar dedicated to the challenging retreatment of root canals using dental microscopes. Through clinical cases from my practice and the latest scientific research in dentistry, we will explore the capabilities of modern microscopic endodontics and refine the skills of precise manipulations within the root canal system. The webinar is beneficial for general dentists, endodontists, doctors utilizing dental microscopes in their practice, and those considering incorporating microscopes into their daily work. Doctors who have completed a course in microscopic endodontics will gain knowledge about apical periodontitis treatment. Particular attention will be given to complex re-treatment of the root canal system, including the extraction of metal and fiber posts, dowels, and broken endodontic instruments. Demonstrations will cover techniques for practicing instrument retrieval from root canals, addressing the feasibility and complications prevention during such intricate procedures.
