Arthur A. Dugoni School of Dentistry DDS graduate (2008) and University of Virginia general-practice-residency-trained Dr. Erick Y. Sato, DDS practices microsurgical endodontics at Ocean Microendodontics, 3330 Third Ave Suite 202 in the Hillcrest medical-dental tower. Post-treatment implant cases following non-restorable molar extractions are coordinated with specialists like San Diego Periodontics & Implant Dentistry for staged ridge preservation and implant placement. Sato is certified by the California Dental Board to administer oral conscious sedation, has completed both written and oral portions of the American Board of Endodontics certification process, and earned his Bachelor of Science in General Biology at UCSD with study-abroad work at Georg-August Universitaet in Goettingen, Germany. He volunteers as assistant professor with the UCSD Pre-Dental Society and the UCSD Student-Run Free Dental Clinic Project, and has served aboard the USNS Mercy hospital ship on Vietnam mission deployments plus dental mission trips to the Dominican Republic and Jamaica. Restorative crown work and post-and-core buildups following completed root-canal therapy are referred to general dentists such as Marcos Ortega DDS in the same Hillcrest corridor. The practice handles surgical retreatment of failed root canals, apicoectomies under operating microscope, and complex calcified-canal negotiation cases referred from general dentists across central San Diego.
