I am definitely not trying to be a party pooper, but make sure that you are allowed to be doing what you're doing in his office. I don't know if adcoms would really care but given that dental ethics is a big issue, if they know of the NJ laws and know you're doing something you 'legally' can't, I don't know if that would cause a problem or not with them. I live in NJ too and work at a multi-specialty practice, and because I'm not an RDA I am not allowed to do too much in ortho because in the state of NJ (it may be national, I haven't looked into if it's just statewide) you have to be an RDA (CDA doesn't cut it) to do basically anything that involves being in the patient's mouth, i.e. removing bands, placing brackets, taking impressions, etc. etc. The orthodontist at my office doesn't want to get himself in trouble so he only uses RDAs- those who aren't registered like me work with the other specialists and the generalists. When I do work with him it's just to pass him instruments or brackets, stuff like that, but I can't directly be in the patient's mouths (other than general suctioning and retracting). I have learned a LOT more working as an assistant than I had just shadowing, so I wish you the same, and most of all have fun 🙂
And btw, just to restate, I'm not trying to put you down or anything, I just don't want you to get in trouble with adcoms or anything. And I realize that more than one person on this forum has been allowed to do something by a dentist they've worked with or shadowed that they probably legally shouldn't (what comes to my mind is the guy who claimed he was allowed to extract a second molar or something... lol)
