Department of Conservative Dentistry and Endodontics conducted a guest lecture on “Clinical applications of Cone Beam Computed Tomography in Dentistry". The lecture was presented by Dr. R. Dinesh Kowsky, Senior Lecturer, Dept of Conservative Dentistry and Endodontics, Meenakshi Ammal Dental College and Hospital on 11.1.19 at Deccenial Hall, Saveetha Dental College. In dentistry, successful treatment outcome depends on correct diagnosis and treatment plan. CBCT being three dimensional, helps in the early diagnosis of endodontic pathosis, which leads to a predictable treatment outcome. The appropriate utilization of CBCT in clinical practice may revolutionize the way we treat the patients. This lecture focused on fundamentals of CBCT and it’s usefulness in the management of different endodontic conditions.
