Visited Dr. Ho for a routine 6 month exam and cleaning. Digital x-rays were taken during the exam. Less x-ray radiation than typical x-ray machines found in other dental offices. Helpful in educating /explaining what my options were on a possible crown. Good chair-side manners. Very gentle while doing routine cleaning. Waiting area was clean and comfortable. Cannot comment on sterilization practices because I did not see whether proper safety measures were taken in between patient change. A thought did occur to me as to whether the saran wrap covering the computer keyboard was changed before seeing me during my appointment.
