Research Clinic

Research Clinic

The UAB School of Dentistry BioHorizons Research Clinic was completely renovated in 2008.  It has 8 complete dental operatories, a dedicated waiting area, chart room/receptionist office, coordinators office, conference room, sterilization area, equipment storage, and surgical suite.  Each operatory has digital handpieces, high power LED curing lights and the clinic has a new phosphor plate digital radiograph system purchased in 2016.  The clinic uses 2 Cannon DSLR cameras for intraoral photography.
