if you wanted to stay in the dentistry, would it be easy to continue the program or did you have to start fresh?
When I first started in the field of dental x-ray laboratory roentgenography, there were no licensing requirements and the schooling was 'on the job'. I was fortunate to be taught by the grandson of the doctor who developed the 'long distance, right angle' technique that became excepted as the standard method for oral x-rays. Eventually, California required licensing and a school curriculum. Current technicians like myself were 'grandfathered' in and we were just required to pass the test.
Technology has changed so much over the years that some schooling in the new technology would be needed I'm sure. This would include both the x-ray equipment and the means of 'developing' the images which are all digital now. We also specialized in those tracings done on a profile view x-ray of the skull and in my office, I used a linear tomogram for studies of the TMJ (Temporal Mandibular Joint). I believe much of this is now automated too.
I don't think it would take long for me to brush up on anatomy, etc. but the most difficult thing for me to overcome at this stage in my life is in dealing with kids and teenage patients all day long.
I think I'll just stay retired.
