Especially in cases like smoking. It can cause discoloration. Then, is drinking less harmful than smoking? It's hard to compare the severity. Since it's alcohol... Wouldn't it disinfect? Mouthwash = Soju. Soju = Mouthwash. Are you confident you can spit it out like a gargle? [Not confident at all] Hahahaha. [Changing Majors] [Jeongwaja] Tap tap tap tap. [Jeongwaja climbing the stairs] [Unusual breathing] Jeez.. [Cardio from the morning] Huff huff. [Sinyeonsu station climb complete] Huff. [Current physical condition at 33] [Greeting] Where is the escalator? [Workout complete] Hahaha. Hello everyone. I review. [Stamina issue] All... The majors in the world. [Catching breath] Phew. [Boosting energy] This is Jeongwaja, Lee ChangSub. [Fully recovered] Yes. Wait a minute before we ask about the school or department.

[Air Force D-day?]
How many subscribers do we have now? [As of filming date.]
6,000 left. If we ask a professional hacker, [Already achieved.]
Can they lower it? I kind of want to lower it. They might lower it. [Real repeat offender.]
Then you’ll get caught. Hahaha. Anyway, today we’re visiting a health-improving school. Today, it’s Gachon University. [Medical Mecca.]
We’re heading to the Medical Campus. From what I know, the Medical Campus only focuses on medical-related fields. [Medical Avengers.]
It’s a campus where they gather. [First visit for repeat offenders.]
We’ve never been to a place like this. There’s a famous place in Incheon. [Top-level general hospital.]
Called Gachon Gil Hospital. - Oh?
- It's under the same foundation. [If it's Gil Hospital?]
That... that person? [Gachon University celebrity.]
Madam Gil. [Lee Gil-ya/President (92 years old).]
Madam Gil, who seems to be frozen in time...

Anyway, this Medical Campus. [All medical fields, come on in.]
Which department will I be visiting today? Today's department is Say, Ah. Ah, The Department of Dental Hygiene. Ahh. [Incredulous reaction]
What the heck, heheheha. [Say Ah!] [Based on professional medical knowledge] [Training dental hygiene experts] [Gachon University Department of Dental Hygiene]. Have you been to the dentist recently? Recently [Checked in at the dentist].
I went for a scaling. How many times a year do you get it done? [According to a friend]
I heard from a friend in the dental department. Actually, scaling [Monthly event].
They say once a month is the best. [New information]
Oh.. [Interested in benefits]
Am I getting a free scaling today? [Healthy smile] Wait a second, time. So, if it's the Dental Hygiene department today [Can I check out the teeth?]
Do I get to do practical training?

[Debut as a dental hygienist?]
Can I try removing someone else's tartar? [Debut as a dental hygienist?]
Can I try removing someone else's tartar? [Open-ended]
You could either do it or have it done to you. Oh, I could have it done to me? [Actually not bad]
If I can have it done, isn't that good for me? [Actually not bad]
Free scaling? [Looks fun]
But I'm a bit curious to try doing it. If something goes wrong, I might end up grinding our students' teeth... [Heading to school]
Let's go get a scaling. [Looking for test subjects]
Is there anyone who wants to get scaling from me? [Sudden silence] [Sigh..]
Okay. [Confident walk to school] [Assertive]
Where are you going? [Hey]
Come here. [Late for class]
Oh, class? Class, oh sorry. [Running while holding hands with a lover]

[Unnecessarily jealous]
Let go of the hand and go. [Excuse me.]
Are you a Gachon University student? Yes, that's right. What year are you in? I'm a sophomore right now. You're a sophomore in which department? Radiological Science. [Oh..]
Radiology? - Radi…active?
 - Yes. [Unbiased question]
 Have you been exposed to radiation? [Wha…??]
Hahahahahaha. [Extremely flawed interview]
 What kind of question is that? Hahaha. - This is the Medical Campus...
 - Yes, that's right. [Recovered interview direction]
What's the reason for learning radiation there? At hospitals, we take care of X-rays. [e.g. Radiologic technologists]
CTs, MRIs, that sort of thing. [Oh, I see.]
Ah yes, X-rays. What departments are here? [Gachon University Medical Campus:
Pre-Med, Pharmacy, Nursing, Physical Therapy] [Biological Sciences, Radiological Science]

[Sports Rehabilitation, Emergency Medical
Technology, Dental Hygiene] Is the medical school not on this campus? The medical school. [Immediate practice possible]
Is right next to Gil Hospital. [So convenient]
Ah, I see. [Legendary Pokémon level]
Have you met Madam Gil by any chance? Yes. [Gachon University Superstar]
Students are thrilled. Ohhhh - Is she a celebrity?
- Yes. [Idol-level popularity]
Feels like everyone's idol. Why, and in what way, is she an idol? Even at her age, she's still [Energetic]
Serving as president. [Current age]
Do you know how old she is? This year. [Really recent update]
Around 92... [Unbelievably youthful]
Wow... She comes to every festival. [Performs on stage?]
Does she sing? Like g.o.d's 'Road? [Pun explosion]
Hahahahahaha. [Arriving at the main gate of the university]
Here it is, Gachon University.

Nice, huh? Doesn't this building look like a hospital? [Hospital playlist visuals]
Maybe it's because it's the Medical Campus. [Clean]
The exterior walls are all white. [Campus living up to its name]
It just really looks like a hospital, doesn't it? [Finding the campus map]
It's nice. So, this much area is for the nursing college? [Large buildings]
And this much behind is for the pharmacy college? And all this is the medical science college? [Campus feature: very small]
But that's all there is? [Touring the campus] [Spotting students]
Oh. [Approaching quietly] What are you studying? [Unexpected interview] What year are the three of you in? We're in our 3rd year. [The senior]
I'm in my 4th. What department are you in? Physical Therapy. [Got it]
Physical Therapy. Oh no, me again. [Already changed majors]
Went to the Physical Therapy department.

And got stung again, of course. [Not a taser.]
Buzz, buzz, buzz. [Jeongwaja effect?]
I saw Jeongwaja and decided to join the Physical Therapy department. [Oh?]
After seeing Jeongwaja - You joined the Physical Therapy department?
- Yes, yes. [Default disbelief.]
But you're a senior? [Really.]
I'm a transfer student. Oh, really? I think we're the same age - Oh, really?
- Yes, yes. 89..? 89... I'm '91? Noona. [Heart fluttering.] What was your previous major? - Linguistics.
- Linguistics? [Found a comrade.]
Oh, you really changed majors. [Major change experience.]
It's very hard. Did you come to the wrong place? [Flustered.] Anyway, alright. [Frequent question.]
How's the cafeteria food? [Answer came much later.]
It's edible. [Got it.] [ChangSub, the martyr at the ready.]
How about leaving a video message for Madam Gil?

Should I leave a video message? Actually, I was planning to [MZ-style communication].
Send a DM. Oh, to Madam Gil? [Let's do it now].
Oh, just do it now, right here. [Avatar video message].
I'll move my lips so. Say whatever you want to say from behind. President, we... [Side gig as a backup lip-sync singer].
We'd appreciate a lot of support. [A beat behind].
We're studying really hard. Could you make the cafeteria food. A bit more diverse? Please. [Okay]. Got it. [LIVE].
This is going out as it is. [Got caught..]. Hahahahahahaha. Right, I was curious about that Madam Gil. [Looking eternally young].
Is still healthy. What do you think is the secret to. Maintaining her youth? [Naturally full hair].
She said it's genetics. Seriously, I was so amazed by her thick hair. I find it fascinating. I'm currently taking hair loss medication. [Excuse me..?]

Suddenly coming out about hair loss... [Hair loss surprise]
Hahahaha. You look like you have a lot of hair, though? This grew after taking the medication. [Sorry to hear that]
Ah... But really. [Getting serious]
Where should I go? For hair loss, though... [Helplessness]
Isn't there nothing we can do? [Failed to hold in laughter]. Did you know that? [More hair loss talk]
Hair loss medication.. people with hair loss. [So excited he's stumbling over words]
If they find a way to overcome hair loss. A man.. if they discover this method. [Director’s cruel angle]
They can win the Nobel Peace Prize, Nobel Physics Prize. They say you can win all of them. Seems like he means it... - Hahahaha
- Of course, I mean it. [Tuition payment] [Medical Science Building]
It really feels like a hospital. [Even the smell is accurate]
Do you know it smells like a hospital here? A dental office smell?

Should I say, It smells like medicine? Oh, wow. [The legendary...]
Madam Gil. [Finally, in her presence] [Overwhelming presence]
Wow. [Thai royal style]
Adorned in gold... What if Madam Gil [Secret of eternal youth]
Has a cure for overcoming both aging and hair loss? [Kingly godly suspicion]
And is keeping it to herself. [Secret in Gachon University's basement..?]
If this were revealed to the world, it could cause great chaos. So, the government restricted it. ['Master race' in real life]
It must not be brought into the world. Like in a movie. You look like her. Are you saying I look like her? [Sentimental]
Mom... [Secret of birth?]
Hahahahahaha. [Back to the department head's office]
Room 502. Yes. [Jeongwaja has entered the department head's office] [Han Kyung Soon /
Department Head: Raise your hand if you're sick].

So, professor, I heard recently. Do we need to get scaling done once a month? Ah, that's not true. Oh, that scammer. Just to make money. What is the optimal frequency for scaling? What is the optimal frequency for scaling? Typically, once a year is sufficient. People over 19 can receive health insurance benefits once a year. To the point. What does the Department of Dental Hygiene study? To the point. What does the Department of Dental Hygiene study? Guardians of dental health. The Department of Dental Hygiene Teaches various activities to help with oral health. For example, Scaling, Fluoride application, and sealants, do you know these? Yes. We mainly learn about preventive activities. Dental nurses. And various tasks supporting dental treatments. You can think of it as encompassing these areas.

[OOTB vivid transfer]
Professor, I'm curious about good toothbrushes. [How to choose and use toothbrushes & toothpaste.]
I use a large toothbrush. [Today's client is a fan of large toothbrushes..]
Do you know what it is? The big one. If the toothbrush size exceeds about 2.5 teeth, it doesn't clean well. [Got it.]
So, toothbrush size should be about 2.5 teeth. If you look at the shape of the teeth. [Teeth are planted in an arch shape.] [It's hard to clean thoroughly with a large toothbrush!] [The toothbrush head should be smaller than 3 teeth.] [Next is how to apply toothpaste!]
And when applying toothpaste. [Client's usual habit?]
Can you show me how you usually apply it? [Just applying it on top.]
I just. You squeeze it like this usually? If you do that. [Wrong way: toothpaste soon disappears and doesn't stay.]

[Realizing it was wrong...] You should press it in like this. [If you press the toothpaste into the bristles, it helps clean the teeth evenly.] [Right way: toothpaste in between bristles.] [Wrong way: toothpaste only on top of bristles.] [Feeling like brushing teeth.] Suddenly, I want to brush my teeth. So, what classes do I have to take today? What comes to mind when you think of dental hygienists? - Scaling? - Correct. You will learn about the process of scaling, which removes tartar. And you'll also attend a class about tissues surrounding the teeth. [Excited.] Do we get to practice? [Yes.] Yes, we do practice. And... while we're at it. [Getting your money's worth.] Could you also check mine..? Let's take a look. [Department head's offer.] If needed, should I do some scaling for you? Oh. [Great benefit.] Sounds good. [Approximately 56,300 KRW/day.] Professor, today's daily tuition fee is 56,300 KRW.

Really? Thank you. [Interlude scaling time.]
Wow, scaling too. Please come in. Wow, what is this? [Gachon University has a dental clinic in school.]
Wow, incredible. [Nerve-wracking visual.]
Wow. [Looks exactly like a real dental clinic.]
It really feels like a real dental clinic here. Do you actually take classes here? Yes. [Definitely can experience a dental practice.]
We actually conduct patient classes here. [Impressive practice room.]
How many chairs are there right now? [FLEX.]
Madame Gil's resources are indeed impressive... [Seated.] [Getting nervous once seated.]
I'm nervous. - Nervous?
- You know, the dentist. [Dental phobia.]
It's always scary. [Talking more due to fear.]
It's just scary. The dentist is scary for no reason. Okay, I will lower the chair. [Going down.]
Oh. [Feeling tense.] Please open your mouth. [Front-row view of the mouth.] [Wider.]
Aaah. You have some stains, do you like coffee?

[Caffeine addict]
I love coffee. Do I have a lot of tartar? [All good]
No, not much tartar. You must brush well. [Relieved patient]
Oh, thank goodness. [Starting in earnest]
Let's do some scaling. Please open your mouth. Suction. [Suction device ON] [Noise alert] [Extreme fear experience] When you brush your teeth, please also brush the front. [Nagging a bit]
Also, brush the inside well. [Focused treatment]
These areas are hard for the toothbrush to reach. [Making excuses] Raise your hand if it hurts. [Raises hand immediately] [Raising hand doesn't stop the process]
Yes, breathe through your nose. It will be done soon. [Music for Snackies' ears] [Removing tartar evenly] [Teacher, please hurry...] [Feet tapping] [Trembling] [Weakening] [Fainting..?] [Finally done]
Yes. [Slurp] [Soul leaves body]. Let’s rinse. - Yes, scaling is done. - Oh.

[Feeling fresh]
Oh, wow, I feel fresh now. Hmm. [Totally relatable..]
There’s a gap between the teeth. Does it feel refreshing?
- Yes, thank you. [Ominous]
Now I’ll do it for you. Did it go well? Eee. Eeee. [Teeth shining]
Eeee. [Class 1 (Clinical Dental Hygiene Practice 1)] [Ventriloquism skill]
Hello, I am a dental hygienist. [99.9% sync]
Doesn’t it look similar to the water dentist? [Spine treatment]
I need to get chiropractic done. Dental chiropractic. [Teeth crunching]
Crack. Crack. Nice. Oh, the Basic Dental Hygiene Practice Room. [Entering the classroom] [Greeting!]
Nice to see you, friends. [Suddenly]
What’s with this helmet, what is this? [Not a hair loss treatment device] [Fascinated] Isn’t this that thing? From X-Men. [Telepathy amplifier]
Is it Cerebro?

Huh? Ah. [Not X-Men.]
It was a facial model like this. [Looking around.]
Wow, does every seat have this? [One head per person.]
Is this for each individual person? Yes. [Curious.]
How do you make this tartar? Oh, for today’s class. [DIY tartar.]
I stayed late yesterday to put it on. Oh, you put it on yourself? [Looking around.] Which toothpaste is good? [Toothpaste tips.]
I don’t really look at the brand. When you look at the ingredients on the back, Fluoride must be. [Cavity prevention effect.]
I only pick ones with over 1000 ppm. Ohhh. [Remote question.]
How often do you change your toothbrush? [Monthly subscription style.]
I change mine about once a month. Once a month? That’s pretty often, huh? I use mine until the bristles. [Toothbrush destroyer.]
Are worn down to the base before changing it. [Clinical Dental Hygiene Practice 1 Major (2 credits).]

[Scaling practice using hand instruments] [Professor Han Kyung-soon /
Department Chair we saw earlier]. Let's briefly review the theory [Scaling practice],
and then move right into practical training. [Sickle scaler: Gingival margin
(boundary where teeth and gums meet)]. [An instrument used to remove
tartar present on the upper part]. It can be used on the front teeth area and also on the molar area. [Question]
Professor, what are front teeth and molars? Ah, the front teeth are [Incisors, canines].
The 'front' teeth. Teeth that are at the front. [Molars]
Molars are the teeth at the back. Ahhh. The shapes of teeth are different, like this. When we remove tartar [Various shapes],
because the shape of each tooth is different and their positions are different. [Different scalers].
The instruments we use also differ. [Straight type]
For front teeth, the shank (connector) is straight. [Curved type]
And for molars, it's curved.

[Tooth by tooth]
To avoid obstruction by the buccal mucosa, And to allow direct application, I'll demonstrate first. [Practice starts]
And then, we'll proceed with the practice. [Professor's demonstration] [Basic posture]
Set yourself in a stable position. [Basic posture]
Slightly lean your upper body forward. [Modified pen grasp]
Modified pen grasp. Stabilize your hand. [Fix with the ring finger on the tooth]
Stabilize your hand, right? While in that state, the instrument should fit under the tartar. [About a third of the blade]
Fit it and remove it. There should be no tartar left behind, so. [Satisfaction confirmed]
Ohhh. It falls off to the outside, right? Yes, it falls off. Once you're done with the top, here. [Inside of the tooth]
Roll the instrument. [Inside of the tooth]
And remove using only vertical motions. I'll remove all of it... [Urgent]
Ahhh, no no no. [Humbled]
I..I'd like to try removing it, too.

- Shall we give it a try?
- Yes. [Excitement MAX]
Ah, this satisfaction seems like it will be great! [Dentist with a past record]
Lee ChangSub Dental Clinic. [Open your mouth, please]
Ah. [Sickle Scaling 1. Removing tartar from molars]. Do it like this. [Tuck]
 Like this. [Clean removal]
Ah. Just right here, simply. Just like that. [Slip]
Just like that. Just right here, simply. [Remaining tartar]
You smoke a lot, don’t you? [Blunt comment to the face]
You’ve got a lot of tartar buildup. [Notice]. [Speechless]. [Anyway, cleaned molar area]
Ah, much cleaner now. Ah, nice. [Sickle Scaling
2. Removing tartar from front teeth]. [Tartar coming out in chunks]
Wow. Wow, even though it's a model. [Dopamine boost]
It feels satisfying. Drrrr drrrr drrrr. [Typical dental hygiene classroom]
Scritch scritch scritch.

While attending this class, the sound of everyone scraping. [Perfect for a nap.]
Will probably make you sleepy. [Real white noise.]
Drrrr, drrrr, drrrr. But am I kinda doing well? Pffft. [Meaning terribly wrong.]
First, the instrument is wrong. Ah, the instrument is wrong... [Complaining for no reason.]
You should have told me earlier. Until now, this person must have been in pain. [Helpless.]
I was poking with the wrong one. [Changing instrument.]
Earlier, for the front teeth. She told you to use the straight one - Use this one.
- Ah, I see. [Lame excuse.]
This wasn't scraping right from the start. [Clean removal.]
Now it's coming off nicely. You should've told me earlier. Sir, this isn't my fault. For insurance claims. [Passing the buck.]
Please talk to her(?) Once you get proficient, it won't take this long. [Speedrun possible?]
You’ll do it quickly, right?

Normally, about 10 minutes? You should finish within 10 to 15 minutes. Oh, wow. How should I remove this black stain? Scritch scritch scritch. Uh-oh. It's shaking. I think this needs to be pulled out? Sir, um. It looks like the tooth needs to come out. Let me give some anesthesia... Ah, stay calm, it's okay. Raise your hand if it hurts. Ah, no hands? If you get anterior scaling from me. Anterior for 6 weeks. Contact admissions for fully-leveled Proper scaling methods to protect your teeth. Scaling master Professor Han Kyung-soon. Lunch break. Removing tartar is hard. Let's eat outside.

Sounds good. [What's this?]
I'll treat you. - Really?
- Yeah. [Perfect timing]
Can we have meat? [Perfect timing 2]
I like meat. [Acting cool]
Sure. [Great] [Playing toothpick]
I'll get the meat stuck in your teeth later. Great. [High-end meat restaurant]
Is it here? Yeah, that's right. [Wallet in danger]
We're gonna clean out this place. [Company dinner vibe]
Wow, I haven't been to such. Such a meat place in a long time? [Menu check time] [Guaranteed delicious]
Pork King Ribs set, oh, nice. Looks delicious. - Wanna have this?
- Yeah. - Should we ask for three?
- Yeah. [Serious about meat] Excuse me, we’d like to. [Order complete]
Have three Pork King Ribs sets, please. (Owner) May we light the grill? [Grill open]
Sure. What the... [Peek-a-boo] [Huh..?]

[Wait a second.]
Haha... [Realization hits.]
Hahaha. [Here it is.]
Who hides product placements on the grill? [Always a surprise.]
How come I can never predict these. Soft and clean taste of 100% domestic rice! Essence of 100 years distilled soju! Ilpoom Jinro. This is a product placement for Ilpoom Jinro. That was surprising. Ilpoom Jinro? [Snack pick.]
It tastes really good. This liquor is really good. [Perfect for Korean taste.]
It's made from 100% domestic rice. [Amazing.]
100% domestic rice. The cap is pretty. The cap. [Like a diamond.]
So classy. [Can we drink alcohol?]
Is it okay before the next class? [Professor, please look away.]
It's a theory class, so it's fine. [Grabbed.]
Okay, I'll pour a glass for each. [Taste is excellent.]
I remember enjoying this a lot. [Scent is excellent.]
The aroma is really good.

Let's do daytime drinking. Cheers. First glass straight. Everyone bottoms up. Ah, that's good. Delicious. Ahh. Subtle taste. It's really smooth. Clean finish. It goes down smoothly. I have something else to introduce. What is it? New Ilpoom Jinro wow. What is this? First time seeing it. Oak 25? Shimmering appearance. It looks luxurious just by its color. Golden touch. Look, it's gold here. Activated sharp senses. Full of flavor. The aroma coming through seems really rich. Today's side dishes arrive. Table filled up before we knew it. Pork King Ribs set, the epitome of sweet and savory. Grilling. Charcoal grill ASMR. Cooking to a perfect brown. Eyes fixed on the meat. Q. Common phrases in dental hygiene majors? Big tooth reveal show. Can you check my teeth? Oh yeah, definitely. Can you check my teeth?

[Free checkup please]
Sending their photos, asking if they have cavities. Among those who asked to check their teeth, [Emergency patient?]
Have you ever thought, This person needs to go to the dentist immediately? My dad - Oh?

The smell is so rich. Something just really hits you. [Really, really.]
That's right, that's right. [Perfect pairing.]
Ribs with Ilpoom Jinro... In dental hygiene. [Wrap up.]
Let's end with an acrostic poem... Unbelievably distinct aroma and flavor! Aged in wooden barrels and blended! Ilpoom Jinro Oak 25. Hahahahaha. [Q. Career paths in dental hygiene?] [Career paths in dental hygiene: Not only dental hygienist,
but also public health officials, military officers.] [Various career explorations such as implant companies.] [Unfamiliar.]
What do you do at an implant company? [Everything about teeth.]
Promote, research. And also educate. Do dental hygienists also have a license?

Yes, [Dental Hygienist National Exam]. [Graduates and expected graduates of dental
hygiene programs at universities and colleges] take the exam in November-December, and
successful candidates are issued licenses. [Sudden topic change]
What about study syndrome? [First impression reader?]
I look at their teeth first. When you look at people? If their teeth are well-aligned, [Ideal type in dental hygiene]
They look handsome. [Tooth alignment flirting?] [100% sync]
Oh, you're handsome, good-looking. Oh right. [Bursting with curiosity]
I have something I'm curious about. [Useful and fascinating tooth dictionary]
Useful common knowledge about teeth. [Q1. When should you brush your teeth
 after drinking coke?] [Waiting is necessary]
It's better to wait about 30 minutes to an hour before brushing your teeth. [Logically thinking]
Wouldn't it be better to get rid of it immediately? [Carbonation is acidic, which can erode teeth]

[You should brush your teeth
30 minutes to 1 hour later.] [Cola.. brushing.. noted...]
Oh, I think I understand what you mean. [Q2. Can cavities be transmitted by
kissing a baby's lips?] [If an adult kisses a baby's lips,] [There's a possibility of transmitting cavity-
causing bacteria 'mutans streptococci.'] [At the very curious age of 33.]
Can cavities be transmitted by kissing? [Of course.]
Bacteria can be transmitted. Now, when you kiss. [Tooth check.]
Wait, let me see your teeth first. Oh no, this won't work. [Mind blown.]
Treat your cavities before kis... [Class 2 (Oral Physiology).]
Great, oral physiology. [Let's go for the second period.] [Packed classroom.] [Packed classroom.]
Wow, there are a lot of people. [Overwhelmingly female-majority.]
Whoa. Hi. [Unfamiliar.]
Oral Physiology.

Nice to meet you. What kind of class is this? You dissect the whole mouth. Dissect the whole mouth? You learn by dissecting. Learn about the tongue and gums. Learn about saliva too. Learn about saliva and the tongue? Is this a joke or what? Have you been to the second floor? Oh, I've seen the portrait. You have to take a photo there. Did you take a photo? Oh, no. It's a tradition to take a photo in the same pose. Or you'll incur her wrath. Like a robot duck again. Watch them lie to me again. Hello, Kim Ji-yeon, Professor. Did everyone have a good meal? Oh, professor. Oh, that scared me.

[Uncontainable energy] [Awkward]
I'm sorry. [Keep the questions going.]
Does alcohol or smoking significantly harm oral health? [Obvious question.]
Yes, of course. Especially smoking, for example. [Full of harmful substances.]
Can cause staining. [Grasping at straws.]
Then, is drinking less harmful than smoking? [About the same.]
Isn't it impossible to compare the severity? [Perhaps.]
Do you drink... often...? [Uncomfortable.]
Well, uh... [Grasping at straws 2.]
Since it's alcohol... [Miracle logic.]
It might act as a disinfectant. [Transfer student logic.]
Mouthwash = Soju. Soju = Mouthwash. [Like mouthwash.]
Can you spit it out? [Not confident.]
Hahahahahaha. [Oral Physiology major (3 credits).] [Understanding the structure and function
of teeth and surrounding tissues.] [Basic question.]
Where is the oral cavity in oral physiology?

[Show with your body]
Oh, Yes, inside your mouth. [This is ridiculous...]
If many teeth are lost, what problems would arise? [Worst-case scenario]
You won't be able to chew. [Correct answer]
The chewing function will decrease, and [Unclear pronunciation]
it will become difficult to speak clearly. And [Cannot savor flavors]
You might not be able to taste well. [Just imagining it is sad]
It's a very sad situation. Therefore, oral health [Importance of oral care]
is closely related to quality of life. This is a familiar image. Teeth consist of enamel, dentin, and [Nerve distribution]
the pulp located at the core. Inside the tooth [Surface of the tooth]
First, let's look at the enamel. Enamel is the hardest part of our body. [Rock-solid]
It's a very hard tissue. The characteristic of enamel is [Biggest strength]
that it's very strong. [Biggest weakness]
But cannot regenerate. So if a tooth breaks, it can't be repaired?

Yes, that's right. [Got it, got it.] And if you look at the bottom of the tooth, [Root apex opening.]
There's a very small hole. Through this small hole, often, [Pathway for nerves.]
It's connected between the pulp and surrounding tissue. The one beside it, the Accessory canal. [What is that?]
What is that? [Good boy.]
That's an excellent question. [Foreseeing what's next.]
Because in the next slide, we'll explain this. [Eager top student.] This part you asked about. [Next slide.]
Similar to the root apex opening, [Another pathway.]
It connects the pulp with the surrounding tissue. It's that part of the tooth. [Question here.]
Now, what do you think this red part is? Pulp. [Out of sync.]
Pulp. Then, professor. [Curious mind.]
When doing endodontic treatment, are we dealing with that pulp? That's on the next slide. [Always a step ahead.]
There's always something surprising. The question you just asked.

[= Endodontic treatment]
During root canal treatment, it's called pulp extirpation, which is removing the pulp. [Automatic reaction] [Damage to tooth nerve]
If the pulp gets diseased, [Infection issue]
inflammatory substances can leak out. [Reason for endodontic treatment]
And cause problems in the surrounding tissue. [Reason for endodontic treatment]
And cause problems in the surrounding tissue. [Reason for endodontic treatment]
You would undergo root canal treatment. So, the scraping sensation at the dentist. [Everyone's fear]
Was them scraping that? After removing the pulp, the dentin layer connected to it
might also be affected. So, scraping is the process of. [Chills]
Expanding that dentin layer. [ex. Crown, amalgam, resin, ceramic..]
They disinfect it and completely seal it with dental materials. [Ever experienced endodontic treatment?]
Have you ever had a root canal treatment? [Extreme fear of endodontic treatment]
I had a very painful.

Treatment on a molar once. [Vivid story]
