After completing my DDS, I started work in private practice, and in 1996 I began my faculty career at the same University as a Professor in Endodontics. During my academic career, I finish my Master's in 1998, my Ph.D. in 2002 and, I received a promotion for Associate Professor in Endodontics in 2008. I coordinated the Endodontic Clinics for more than ten years and Endodontic Certification Course for five years. Moreover, for more than 20 years, I have been actively involved at a Dental Trauma Center. I have done uncountable numbers of procedures in all aspects of Endodontics. I am a member of some professional organizations, including the American Association of Endodontics (AAE), International Association for Dental Trauma (IADT), and the International/American Association for Dental Research (IADR/AADR). I have expertise in Root Canal Therapy, Dental Emergency, Dental Trauma, Apical Surgery, Endo-Periodontology, Endo-Prosthodontic, Endo-Ortho, Caries Excavation, and Pulp Conservative Treatments. I believe in Evidence-Based Dentistry, using the modern and better approach for Endodontics.
