| Provider interview themes

Themes	Supporting quotes
Most liked features	“The pictures were great. That’s what I wanted, ‘cause I’m not a dentist. I don’t know what I’m supposed to be looking at.” “I liked the first screen asked the questions, have you had this, this, yes or no checkbox for the assessment.”
Least liked features	“To me, it seemed-I mean it had good information, but it seemed wordy. Like I was just reading from the screen. I guess I would have to try and put it into my own words or something.”
Unused features	“I didn’t realize there was a picture. No one said anything about a picture icon.” “Just if there’s a tutorial how to use it or something…I kind of [just went] went click, click, click.”
Usefulness of the provider and patient summary	Provider Summary: “I think it’s kind of redundant.” Patient Summary: “It gave the patients something that they can take home and look at later and recap what we talked about.”
Usefulness of brief motivational interviewing	“I think all of the things that you asked them were very reasonable to do…those are easily accomplishable goals…give them a visual thing” “I’m not sure you’re gonna get people motivated to spend money out of their own pocket to go to the dentist…Because you got to hook them. And as soon as they walk out that door, they’re not gonna think about the dentist anymore”
Patient–provider communication	“It reminds me to hit the hot spots…” “I think it’s a bit lengthy and I think after about the third question that I kind of lost them, a lot of them. You’re just kind of wandering off in space”
Merits of the app	“It prompts us to be a little more in detail, especially the pictures. Those were great.” “There’s just the right amount of information. I wouldn’t give any more or any less.”
Demerits of the app	“I felt like an idiot when I was going over those ‘That’s great’ [in the Advise section]. That was a little childish.” “Those appointments take forever. So, it’s a little annoying to be doing another piece of a puzzle, which is appropriate, but again, it’s just time consuming.”
Suggestions for improvement	“I think you should have some follow up with pictures to give the patients …’cause they’re looking in the mirror and they don’t know what’s normal and what’s abnormal.” “Maybe [do it] on intake, that way you’re not quite as crunched for time, you can go over it.”
