All pre-doctoral and post-doctoral dental students/residents participate in formal didactic training on HIV disease and subsequently the provision of clinical oral health care to patients with HIV/AIDS. Only dental residents, postdoctoral students, and third and fourth year pre-doctoral candidates participate in providing direct clinical care to these HIV/AIDS patients. However a clinical clerkship of first year dental students affords them the opportunity to interact with clinical patients in conjunction with third and fourth year dental students interviewing and assessing HIV patients. The pre-doctoral didactic hours used in medical evaluation, oral health assessment, and patient management are done through the courses of physical assessment, Health Promotion and Disease Prevention, Pathophysiology and diagnosis and patient treatment planning. Patient management courses address interventional skills for at risk populations. Semester classes in Psychiatry cover management of addiction including opioids and other drugs. Pain Management courses include focus on use and risk of prescription drugs. The total number of hours of providing direct clinical services in the pre-doctoral program is estimated with the estimate based on the actual patient visits at our on-site clinical training program. All the students, Fellows, and residents at Columbia University College of Dental Medicine receive didactic instruction in medical assessment and oral health management (direct clinical care experience) for people living with HIV/AIDS as part of the curriculum in the courses of physical assessment, Health Promotion and Disease Prevention, Pathophysiology and diagnosis and patient treatment planning.
