About us

Trinity College and The Dublin Dental University Hospital (DDUH) possess the largest dental school in the country. It has an established reputation in its tripartite mission of education, research and patient care. The latter is provided in the only secondary and tertiary care clinics in the country. It possesses a critical mass of academic staff across many disciples, making it attractive for practitioners to complete postgraduate training and Continuing Professional Development (CPD). 

Trinity has established this postgraduate certificate course in Orofacial Pain to be delivered in collaboration with the Herman Ostrow School of Dentistry of University of Southern California. The ESC School was established in 1897 and has shaped talented students into outstanding dentists and dental hygienists since its inception. The Ostrow School of Dentistry is home to some of the brightest names in oral and craniofacial biology, stem cell science, biofilm research, clinical investigation and more. 

The proposed new postgraduate certificate course is in one of the most attractive clinical areas for dental practitioners and its format will facilitate those in dental practice. In order to ensure its professional and academic quality the School of Dental Science and the DDUH have teamed up with the Herman Ostrow School of Dentistry of the University of Southern California which is already delivering a similar certificate course in Orofacial Pain specifically designed for the practicing dental professional who wants to improve skills and gains a world leading expertise to deliver the best care for patients with complex conditions.

Welcome to Trinity College and to a pioneering new program

The certificate in Orofacial Pain has been carefully designed to have a dual role. As a standalone program, it will aim to improve the knowledge of dental professionals in Orofacial Pain and Temporomandibular Joint disorders, but it can also act as a springboard for advanced education and possibly a career in pain diagnosis and management. We endeavour to help you realise your full potential.

The course is taught by the Dublin Dental University Hospital using a blended learning approach through the College Virtual Learning Environment, Blackboard Learn and

Blackboard Collaborate in addition to attendance at the hospital for the didactic and hands on portions of the modules. Although the program is mainly online, I would urge you to take the opportunity to immerse yourself into student life and enjoy this unique experience.

Trinity College is an energetic and vibrant University at the forefront of graduate education and we are confident that this new course will meet and surpass your expectations.
