Ep 70: SMILE TALK at the California Dental Association Convention at the Anaheim Convention Center
Salvador Gaytan: It's time! SmileTalk is on the air, featuring the latest news and developments in dentistry, as well as other interesting topics that make people smile. I'm Salvador Gaytan, and I'm here with?
Dr. John Chao: Dr. John Chao. We're going to bring you something that's very entertaining and interesting. We're reporting our experiences, our interviews and people we met at the California Dental Association's annual convention in Southern California, located at the Anaheim Convention Center.
Salvador Gaytan: That's right. You and me, we, we went down there and we -- we had a lot of fun, we interviewed some people and harassed them. Well, you harassed some people actually Dr. John, didn't you?
Dr. John Chao: Yeah, I, I, I got some really nice people, they allowed us to uh, to interview them and uh reveal their secrets to us. So, we're going to share it with our audience.
Salvador Gaytan: I'm surprised security didn't throw you out Dr. John, you were really a rascal.
Dr. John Chao: Well, Cary was real game.
Salvador Gaytan: Uh huh.
Dr. John Chao: And Dr. Brown was also, so uh that, that's actually one of my favorite interviews that day.
Salvador Gaytan: That was one of your full -- and we'll get to that one. We're going to play, umm, I don't know, maybe seven or eight of the -- of our favorite interviews, some different products, uh, services and so forth. But uh, one of Dr. John's uh favorite interviews, he was trying to accost different people for some interesting interviews, and he found a couple of interesting characters, didn't you?
Dr. John Chao: Yeah, actually uh I was first drawn to them, because the uh ladies were very attractive.
Salvador Gaytan: Yes.
Dr. John Chao: And they were laughing and having a good time, so I didn't feel that uh -- I felt comfortable just approaching them and asking them, uh, one of them, uh, "What is the most embarrassing moment you've had in your career?" and she was able to share with us. So, we're going to let the audience listen to that.
Salvador Gaytan: That's right, because uh we were there live interviewing, and but just set this up, at the Anaheim Convention Center it was a huge, huge convention. Floors, I guess you could say, football fields full of products and services, isn't that right, Dr. John?
Dr. John Chao: It was -- it's people everywhere, people everywhere, but people were very -- in very good mood. This is, this is shopping time for dentists, and, and their staff. This is when you go around have fun.
Salvador Gaytan: And, and they -- kind of a vacation time too for the staff.
Dr. John Chao: Vacation time. They, they are paid -- they are paid when they are there, so -- and, and, and those who are not paid, they enjoy being there.
Salvador Gaytan: And some people came from uh -- you know, they had to fly or drive to get down there, because it was in Southern California, this one, although they had one in Northern California too.
Dr. John Chao: Yeah, and yeah, once a year in September they'll have it in Northern California. And uh we, we might go, it'd be interesting to visit that too. But a lot of people were -- you know, every year they look forward to going and this is -- this is the time when you renew old acquaintances, people you've met and your classmates from school, and there's different ways to meet different people. And they of course -- of course, they have after-hours parties everywhere.
Salvador Gaytan: And if you're tuning in, you're listening to SmileTalk. I'm Salvador Gaytan here with Dr. John Chao, spelled C-H-A-O. You can reach Dr. John at 626-308-9104 or your website Dr. John.
Dr. John Chao: C-H-A-O Radio, ChaoRadio.com.
Salvador Gaytan: Or AlhambraDental.com. That's the uh -- the genesis of our interviews. You're going to be hearing those, as we were there live. I'm sure you'll enjoy them. And then we will uh wrap it up at the end.
[Interview Recording - Cone Beam Computerized Tomography]
Dr. John Chao: Alright, this is Dr. John Chao. We're at the CDA Convention, and I'm at a table clinic, uh, where a project is being shown, uh, by a naval officer, also a dentist by the name of Dr…
Dr. James Ward: James Ward.
Dr. John Chao: Dr. James Ward, you're also a lieutenant.
Dr. James Ward: Yes.
Dr. John Chao: So, it's also -- it's also Lieutenant Ward, and he has a uh presentation on Cone Beam Computerized Tomography. Now, this sounds like a CT scan, would you tell us the difference between dental CT and a medical CT?
Dr. James Ward: Well, most often when a, a patient receives a CAT scan, it is more radiation than what a patient would receive if they had a Cone Beam scan.
Dr. John Chao: How much radiation does a conventional CT gets as compared to a dental CT?
Dr. James Ward: Well, it's been compared that it could be as much as a thousand times less than a CAT scan, but from the literature that I have read, it typically uh can be about 80 to 100 times less of a dose when a patient receives a Cone Beam scan.
Dr. John Chao: The Cone Beam scan; how does that, in terms of radiation, compare to the regular dental x-rays?
Dr. James Ward: Well, what's great about a Cone Beam is that it gives a clinician a three dimensional image of the patient's skull, and that can then be sliced, so to speak, and the, the clinician can look at any aspect of the skull.
Umm, roughly uh if a patient has ever had a panoramic x-ray done -- I'm sure many people have had the, the unit pass around their head or rotate around their head. That's about the same amount of radiation that a patient would get if they had a Cone Beam scan, a very low amount of radiation.
Dr. John Chao: So, we're not talking about very much about radiation?
Dr. James Ward: No.
Dr. John Chao: But, the, the benefit would be that the doctor gets a three dimensional view of the patient's uh mouth and the head.
Dr. James Ward: Yes, at very high resolution.
Dr. John Chao: Now, what advantage is there for the patient to have this in terms of a diagnosis? What fields of diagnosis are enhanced by a CT dental scan?
Dr. James Ward: Uh, specifically, a clinician, the overall ability for a dentist to diagnose is increased by about 30%, uh, whether the clinician is trying to find the position of teeth uh to properly diagnose a, a problem with the roots of a tooth or to even plan for the placement of implants.
Uh, his or her ability to, to properly diagnose and plan treatment, it's even being called guided treatment instead of just a diagnosis. A, a clinician can plan ahead of time to avoid potential complications with nearly all aspects of dentistry.
Dr. John Chao: Such as not getting that implant to go close to a nerve?
Dr. James Ward: Yes. Or even sometimes uh blood vessels. Uh, so then the -- when the uh -- at the time of surgery, there are fewer complications as a result.
Dr. John Chao: Now, besides implantology, is there application for CTs in other areas of dentistry such as orthodontics or braces, or even root canal treatment?
Dr. James Ward: Yes, as a matter of fact. Umm, currently Cone Beam is being used to evaluate how efficiently the canals of a tooth or the inside of a tooth can be cleaned by different instruments, and that is helping to develop uh better techniques to have more successful root canals.
Umm, orthodontic treatment can actually be planned from start to finish literally umm before the patient is even -- has even begun treatment with Cone Beam.
Dr. John Chao: Now, with, with a Cone Beam, the doctor can actually project uh what the face will look like after treatment, is that true?
Dr. James Ward: That is true. Even with uh -- with surgery also, if a patient needs their jaw moved forward or advanced backward, uh, if they need a procedure like that, whether it'd be to improve their ability to, to sleep at night due to sleep apnea. Umm, that can be actually be -- it could be predicted, and the images can be shown to a patient before and after.
Dr. John Chao: Okay, okay, you mentioned sleep apnea. Sleep apnea is a condition where the patient doesn't breathe properly during sleep. Would you define sleep apnea for us?
Dr. James Ward: Well, that isn't necessarily my region of expertise, but umm basically as -- my understanding is that sleep apnea umm occurs when the soft tissues, or say for example the tongue or the tissues of the throat, as a patient is laying down, or a person is trying to sleep, as they relax, they fall back and block the airway during sleep. And that can affect a person's ability to sleep, and it can even be dangerous, and in some cases even cause death, in rare cases.
Dr. John Chao: So, for the dentist who does Cone Beam CT, he can also screen for this problem by looking at the size of the throat?
Dr. James Ward: Yes, that is correct. It's a very accurate image of the actual air passage way.
Dr. John Chao: Okay, and talking about accuracy, I see that you have something that says recent study have -- studies have shown that the clinician is more likely to be correct with a 3D scan compared to a 2D. Would you elaborate on that statement?
Dr. James Ward: Yes, as a matter of fact, in, in various studies uh that I read and compiled and, and drew my information from, roughly uh from specialty to specialty in dentistry, it's been found that yes, with, with two dimensional images, a clinician can be wrong one out of three times. But when a clinician is given that three dimensional view, a clinician is wrong less than 10% of the time.
Dr. John Chao: Now, we're talking about certain aspects of diagnosis, isn't it? We're not talking about cavities.
Dr. James Ward: No, we're not talking about cavities.
Dr. John Chao: Yeah, we're talking about…
Dr. James Ward: Let me add something. Now, we were talking about specificity and sensitivity, and when any type of medical procedure or diagnosis or treatment has -- approaches 90%, that's considered to be very, very good in medicine.
Dr. John Chao: Yeah. So, actually, when we talk about one out of three times, we're talking about special situations where we're trying to locate the position of the teeth, which are impacted uh or we're trying to diagnose uh some special conditions regarding the roots and so on. It's not uh -- it's not that the dentists are wrong one out of three times.
Dr. James Ward: Well, unfortunately they're limited by their ability to distinguish the anatomy with just two dimensions.
Dr. John Chao: So, so, we're talking about interpreting 2D x-rays?
Dr. James Ward: Yes.
Dr. John Chao: Specifically, not what the dentist sees in the mouth.
Dr. James Ward: Correct, yes.
Dr. John Chao: So, so, we're talking about one out of three times the diagnosis of x-rays uh may not be correct uh compared to the 3D images.
Dr. James Ward: A clinician is more likely to have an accurate diagnosis using three dimensional imaging.
Dr. John Chao: Okay, good. Thank you very much, Dr. Ward, and we appreciate your time.

[Interview recording - Dr. Cary-Lyons - Loma Linda]
Salvador Gaytan: Hi, I'm Salvador Gaytan, and uh we're here at the California Dental Association convention, and uh I'm here with…?
Dr. John Chao: Dr. John Chao. I just accosted two people out of the isle, and they turned out to be very interesting, now we're going to interview them.
Salvador Gaytan: Are you sure they're interesting?
Dr. John Chao: Well, we're going to make them interesting no matter what. Are you ready, you guys?
Dr. Cary Brown: I'm ready, yes.
Amanda Lyons: We're ready.
Dr. John Chao: This is Dr. Cary Brown, and that's Amanda Lyons from Loma Linda, dental assistant.
Salvador Gaytan: Okay. Now, we have the -- we have the doctor here, uh, Mr. Brown. Where, where is your practice, Dr. Brown?
Dr. Cary Brown: I'm in Murrieta, California.
Salvador Gaytan: Murrieta, California, okay. And you have here -- we have here Amanda, where are your duties, Amanda?
Amanda Lyons: Umm, I do everything for the doctor.
Dr. Cary Brown: She makes me laugh, that's her duties, to make us laugh. She's the office clown.
Salvador Gaytan: Office clown, okay, okay, does that pay well?
Amanda Lyons: It pays alright I mean, it could be better.
Dr. Cary Brown: She drives a new car; she drives a new car, so I guess [crosstalk].
Amanda Lyons: That's from all the money that I saved, not from this place.
Salvador Gaytan: I think she's looking for a raise, but we'll get to that later. Dr. John, what do you want to ask?
Dr. John Chao: Well, umm, what makes you think you deserve a raise, besides the jokes, besides the jokes?
Amanda Lyons: Yeah, I had to take up comedy to pay for the bills.
[Laughter]
Salvador Gaytan: Now, what is it, are you -- are you behind the desk or are you -- what is your…?
Amanda Lyons: I'm an assistant.
Salvador Gaytan: You're an assistant, okay, very good.
Dr. Cary Brown: Chair side assistant, yeah, she, she helps us out with the orthodontics and the surgeries and uh the fillings, you know routine procedures.
Salvador Gaytan: So, what is your specialty?
Dr. Cary Brown: I'm a general dentist, uh, but we do a little of everything in our office. We do umm implants, orthodontics, umm. I like the technical things; I've been doing this for 15 years, so the fillings and the basic things are a little boring now. So…
Salvador Gaytan: Do you have 100% satisfaction from your patients?
Dr. Cary Brown: No, I don't.
Salvador Gaytan: Oh my God, but probably close, probably very close.
Dr. Cary Brown: I don't think any office does.
Dr. John Chao: Well, he's got Amanda to make up the -- you know, the difference. So, that's -- that's what makes it important, you have to give her a raise to keep here there.
Salvador Gaytan: That's true, that's true.
Dr. John Chao: Uh, uh, otherwise we might hire her away.
Salvador Gaytan: Well, you never know, you're far away though, Dr. John, you're far away. So, now Amanda, how long have you been with uh the good Dr. Brown?
Amanda Lyons: Almost four years.
Dr. John Chao: Now, tell me what is the most embarrassing thing that you've seen happen to your doctor?
Amanda Lyons: Oh! [Laughter]
Salvador Gaytan: Can we talk about that?
Amanda Lyons: Uh well, out -- stuff outside of work.
Dr. Cary Brown: At the office, at the office only.
Amanda Lyons: Oh dang it, I could go on for days. Outside the workplace…
Dr. Cary Brown: I know one of the most embarrassing things that happened to Amanda…
Salvador Gaytan: Let's go ahead, shoot.
Dr. Cary Brown: She is such a good hard worker, and uh she was uh cleaning the office one day, scrubbing away. She was scrubbing the cabinets, scrubbing the chairs, scrub down to the floors, and stood up so quickly, uh, she bumped her head on the cabinet, cut her head open, blood is gushing all over.
Amanda Lyons: Gushing blood everywhere.
Dr. Cary Brown: Umm, I had to move onto another patient, so umm our nice patient got up and held her head with a rag, and escorted her to the bathroom.
Amanda Lyons: Then wiped the floor, the blood, the trail.
Salvador Gaytan: Now, that's my kind of patient.
Dr. Cary Brown: Yeah, so anyway, yeah, she was pretty embarrassed. Umm, did you have to go to the clinic for that one?
Amanda Lyons: Yeah, and they just glued my head.
Dr. Cary Brown: They glued her head.
Salvador Gaytan: Last question, Dr. John.
Dr. John Chao: Have you been the same since?
Amanda Lyons: Oh yes, I've been even better.
Salvador Gaytan: Alright, Dr. Brown, we'll give you a plug here. What's your -- do you have a website, a phone number where patients can contact you, in Murrieta, is that right?
Dr. Cary Brown: Murrieta, California, right. It's in South Riverside County. Our website is StarwhiteDental, our office is called Starwhite. Is that on camera on that thing, you can get a picture of our nice…
Salvador Gaytan: No camera, just audio right now. What's your phone number, doctor?
Dr. Cary Brown: Phone number is 951-698-4426.
Salvador Gaytan: Alright, that's…
Dr. John Chao: And you can look up Cary Brown, C-A-R-Y B-R-O-W-N.
Salvador Gaytan: Alright, that's a wrap ladies and gentlemen.

[Interview recording - Neil Feldis & Melanie - Whitening Product]
Salvador Gaytan: I am Salvador Gaytan with SmileTalk, here at the California Dental Association and I'm here with also…?
Dr. John Chao: Dr. John Chao, we are interviewing uh a product uh that whitens your teeth.
Salvador Gaytan: That, that's right, and we have a uh product made by Heraeus, and we're interviewing here uh Neil and Melanie, and they're going to tell us about uh, uh, the whitening and uh, a new dimension to it. Neil, how are you?
Neil Feldis: Very good, thank you, how are you?
Salvador Gaytan: Fantastic. Okay, Neil, tell us about your product quickly, what do the viewers need to know?
Neil Feldis: Well, Venus White is a simple solution for in-office, take-home and over the counter trays, has carbamide peroxide in the take-home, and it is hydrogen peroxide in the in-office and over the counter medication.
Salvador Gaytan: Okay. And Melanie, you were mentioning something a little earlier about the product. What were you saying about it?
Melanie Truong: You know, one of the things that's so great about our product is that we have the active ingredient of Sensodyne, which is potassium nitrate built in, which will help with the patients and sensitivity. And I know that Dr. Chao, I know you're going to be concerned about pushing the products, the material all over the gums. Our materials are very viscous, thick, so wherever the patients place it on their teeth, it's going to stay right there.
Salvador Gaytan: That's pretty important, isn't it, Dr. John?
Dr. John Chao: Yes, how long does it take to work?
Melanie Truong: It depends on which solution you want to go with. The in-office, umm, it's a 50 minute interval, so for you to use it on a patient, probably an hour.
Dr. John Chao: For the patient at home, for the patient at home, how many days would it take before their teeth get white?
Melanie Truong: You're going to see the difference, umm, in your teeth in about two days, two, two sessions.
Salvador Gaytan: Okay.
Dr. John Chao: And how long does it take for the uh solution to completely work?
Neil Feldis: The solution works umm 22% for one hour, and then it will start to break down, and then the 16% is six to eight hours before it starts breaking down.
Dr. John Chao: But how many days would it take before the patient gets the maximum benefit?
Neil Feldis: Maximum benefit is seen in seven days with the take-home's 22% or 16% solution.
Dr. John Chao: Now, that's, that's pretty quick.
Salvador Gaytan: That is fantastic, and uh you can pick up this product at your local dentist. Uh, can these products be picked up outside the dentist's office?
Neil Feldis: Unfortunately no, everything is available through your dental provider.
Salvador Gaytan: Okay, you heard it, go to your dentist, isn't that right, Dr. John?
Dr. John Chao: Regularly, please.
Salvador Gaytan: Alright, that's a wrap.

[Interview recording - Salivary Diagnostics]
Dr. John Chao: Alright, here we are at the CDA uh convention. We are uh talking to Captain Melissa Sheets, isn't that right? Umm, captain Sheets is presenting a clinic on the use of salivary diagnostics.
On our show, we previously have talked about how saliva can be used to diagnose different diseases and how dentists can be uh involved in the diagnosis of different diseases that can be shown through testing of the saliva. Uh now, Captain Sheets, would you tell us, uh, what diseases cannot be detected through the use of uh salivary diagnostics?
Melissa Sheets: This is all early research that's being done by several dentists across the country. A lot of them are in California. They've had good early research with Oral Squamous Cell Carcinoma. They found some biomarkers for breast cancer, and they're working on also Alzheimer's, Huntington's disease, umm, diabetes, colorectal cancer. So, it has promise for a lot of systemic diseases.
Dr. John Chao: Well, this is very exciting. So, somebody can go to the dentist, uh, spit into something and come out, uh, having been screened for some very uh significant diseases?
Melissa Sheets: Yes, that's what they're working on.
Dr. John Chao: Now, how far in the future do you think that is, before that becomes realistic?
Melissa Sheets: From the research that I've read, maybe in the next 10 years.
Dr. John Chao: Okay. Uh, so far what other diseases or conditions that can be detected by the use of uh using saliva for diagnosis of diseases, what diseases can we diagnose with saliva at this point in time?
Melissa Sheets: They do have a test for HIV that's already on the market. That's in use.
Dr. John Chao: Okay, is there anything else that we can test for right now?
Melissa Sheets: Not that I'm aware of. They have early results, as I said, but not necessarily for sure. They have -- so far have very good, over 90% specificity and sensitivity, but it's still being researched.
Dr. John Chao: Yeah, now of course saliva can be used to diagnose dental conditions, isn't that -- is that not true?
Melissa Sheets: It is. Umm they also did a study on Matrix Metalloproteinase-8, which is umm something that's been linked to periodontal disease, so they've used that as a saliva biomarker as well.
Dr. John Chao: Now, periodontal disease meaning gum disease, doesn't it?
Melissa Sheets: Correct.
Dr. John Chao: So, you -- we can use saliva to assess the uh vulnerability of a patient to gum disease?
Melissa Sheets: Yes, they're working on that.
Dr. John Chao: How about using saliva to detect how vulnerable a person could be to, to dental cavities?
Melissa Sheets: Not that I'm aware of.
Dr. John Chao: Not, not -- alright now, okay. Very good, thank you very much Dr. Sheets, we appreciate your time.
