0:00:23 > 0:00:24He's Dr Chris.
0:00:24 > 0:00:26He's Dr Xand.
0:00:26 > 0:00:27And yes, he's still got his beard.
0:00:27 > 0:00:30And we're still identical twins.
0:00:30 > 0:00:33Your body's amazing and we're going to show you why.
0:00:36 > 0:00:38We're head-to-head in Operation Takeover.
0:00:38 > 0:00:40This is very, very hard.
0:00:40 > 0:00:41- BOTH:- Man overboard!
0:00:41 > 0:00:43Ouch and About hits the wards.
0:00:43 > 0:00:45That might be the squishiest nose I've ever seen.
0:00:45 > 0:00:47First aid is back.
0:00:47 > 0:00:48So we do need to get Xand to hospital.
0:00:48 > 0:00:51Meet our brilliant new Ouch-patients.
0:00:51 > 0:00:53I'm off to my physio appointment.
0:00:53 > 0:00:54And our lab experiments...
0:00:54 > 0:00:56- Ta-da!- ..will blow...
0:00:56 > 0:00:57Pretty spectacular, isn't it?
0:00:57 > 0:01:00..your mind!
0:01:00 > 0:01:02Are you ready to join us?
0:01:03 > 0:01:05You're crazy!
0:01:05 > 0:01:06Woo!
0:01:08 > 0:01:09I can't see a thing.
0:01:13 > 0:01:14Coming up today...
0:01:14 > 0:01:15..on Operation Ouch!...
0:01:20 > 0:01:22There's a bang on the lab roof.
0:01:23 > 0:01:24Chris has some advice.
0:01:24 > 0:01:26You've got to be sick into the air
0:01:26 > 0:01:29so that it goes over all the people behind you.
0:01:30 > 0:01:33And Xand opens wide.
0:01:33 > 0:01:34But first...
0:01:34 > 0:01:35..let's see...
0:01:35 > 0:01:37- ..who's turned up... - ..in the accident...
0:01:37 > 0:01:39..and emergency department.
0:01:43 > 0:01:46At the emergency department in Sheffield, nine-year-old Tenny
0:01:46 > 0:01:50is waiting with her mum and a heap of bloody tissues.
0:01:50 > 0:01:52Who NOSE what happened?
0:01:52 > 0:01:54I suddenly started having a nosebleed at school
0:01:54 > 0:01:57and then I had to go home because it was that big.
0:01:57 > 0:01:59Crikey! Tell me more.
0:02:01 > 0:02:04Tenny loves skipping with her mates.
0:02:04 > 0:02:07Don't we all? I skip loads of things.
0:02:07 > 0:02:09Washing up? I don't think so!
0:02:09 > 0:02:12Picking up my smelly socks? Yeah, right!
0:02:12 > 0:02:13That's MY sock!
0:02:13 > 0:02:16Anyway, Tenny loves jump rope skipping.
0:02:16 > 0:02:18Well, I do that, too.
0:02:18 > 0:02:21She was skipping away in the school playground...
0:02:21 > 0:02:22Boing-boing!
0:02:22 > 0:02:26..when her nose began to bleed and just would not stop.
0:02:26 > 0:02:27Get her some tissues.
0:02:27 > 0:02:28- BOTH:- Ouch!
0:02:30 > 0:02:33Tenny's nose has been bleeding for 25 minutes.
0:02:33 > 0:02:35- All right, come through. - Don't forget your tissues.
0:02:35 > 0:02:36Just in case.
0:02:38 > 0:02:41Dr Alex Damazer to the rescue.
0:02:41 > 0:02:44She must be good because Tenny's nose has just stopped bleeding.
0:02:44 > 0:02:48So today, you've had one that stopped a few minutes ago.
0:02:48 > 0:02:51Tenny has been having nosebleeds since she was three years old.
0:02:51 > 0:02:53She gets them all the time.
0:02:54 > 0:02:57The inside of your nose is lined with lots of blood vessels.
0:02:57 > 0:03:00They're very close to the surface and they're easily damaged,
0:03:00 > 0:03:02creating a nosebleed.
0:03:02 > 0:03:06The damage can be caused by lots of things including dry air,
0:03:06 > 0:03:08sneezing or picking.
0:03:09 > 0:03:12And how do you stop us from bleeding when it's bleeding?
0:03:12 > 0:03:16- I sometimes pinch the soft tissue here.- Tick!
0:03:16 > 0:03:18- Get some tissue.- Tick!
0:03:18 > 0:03:21- Or I use ice.- Tick!
0:03:21 > 0:03:23So you're an expert at nosebleeds.
0:03:23 > 0:03:26Well done, Tenny. That's spot on.
0:03:26 > 0:03:29Let's have a look up your nose.
0:03:29 > 0:03:31Do you always bleed from the same side?
0:03:31 > 0:03:33This side. Your right?
0:03:33 > 0:03:34Yeah, I can tell.
0:03:34 > 0:03:36I'm going to have a chat with one of the others, either
0:03:36 > 0:03:40the registrars or the consultants, and talk about cauterisation.
0:03:40 > 0:03:43Cauterisation is a procedure to seal the blood vessels,
0:03:43 > 0:03:46which will stop Tenny getting nosebleeds.
0:03:46 > 0:03:48Find out if this works for Tenny later on.
0:03:53 > 0:03:55And now to our lab.
0:03:55 > 0:03:58It's time for some big body experiments,
0:03:58 > 0:04:00some of them gory...
0:04:00 > 0:04:02This is not for the squeamish.
0:04:02 > 0:04:03..some extreme.
0:04:03 > 0:04:05It's freezing!
0:04:05 > 0:04:07So are you ready?
0:04:07 > 0:04:10Just don't try anything you see here at home.
0:04:10 > 0:04:13Today we're looking at what makes your ears pop.
0:04:13 > 0:04:16So if you want to know what this is all about...
0:04:16 > 0:04:17..keep watching!
0:04:20 > 0:04:21Hi, Xand.
0:04:25 > 0:04:26Hi, Xand.
0:04:26 > 0:04:28Oh, that's much better.
0:04:28 > 0:04:31- What are you doing? - Oh, what, you mean with the whole...
0:04:31 > 0:04:33HE GROANS ..thing?
0:04:33 > 0:04:34- Yes, the whole... - HE GROANS
0:04:34 > 0:04:36..thing. But also the armband, towel,
0:04:36 > 0:04:39and why are you using my heart as a drying rack?
0:04:39 > 0:04:42Well, I went swimming this morning and I dove down really deep
0:04:42 > 0:04:45and then when I came up, my ears felt all blocked up
0:04:45 > 0:04:47and so I thought, maybe if I just did a bit of this,
0:04:47 > 0:04:48I could get them to...
0:04:48 > 0:04:49POP! XAND SCREAMS
0:04:49 > 0:04:52- ..pop.- I'm glad you brought up ears popping, Xand,
0:04:52 > 0:04:55because today's lab is all about the very piece of body kit
0:04:55 > 0:04:57that enables that to happen.
0:04:57 > 0:04:58Today's lab is all about
0:04:58 > 0:05:01the amazing Eustachian tube.
0:05:01 > 0:05:03My second favourite part of the body,
0:05:03 > 0:05:05after the epiglottis.
0:05:05 > 0:05:07Now, if you've ever swum down deep lake Xand
0:05:07 > 0:05:08or been up in an aeroplane,
0:05:08 > 0:05:10you might have felt your ears popping
0:05:10 > 0:05:13or felt like they needed to pop, but why does it happen?
0:05:13 > 0:05:16Well, it's all to do with keeping the pressure inside your head
0:05:16 > 0:05:19the same as the pressure outside of your head
0:05:19 > 0:05:21in the atmosphere around you.
0:05:21 > 0:05:23And to understand how they pop, take a look at this.
0:05:25 > 0:05:27Wait a minute - what is this?
0:05:27 > 0:05:32Chris, this looks suspiciously like my goldfish tank
0:05:32 > 0:05:36in which live my goldfish, Dolly and Dave.
0:05:36 > 0:05:38Don't worry, Xand, they've just gone on holiday for a couple of days.
0:05:38 > 0:05:40On holiday?!
0:05:40 > 0:05:41PHONE VIBRATES
0:05:42 > 0:05:45"Hi, Xand, we go to the seaside for a couple of days.
0:05:45 > 0:05:47"See you soon. Love, Dolly and Dave."
0:05:47 > 0:05:49Hmm, well, they didn't tell me they were going anywhere.
0:05:49 > 0:05:52Anyway, whilst they're away, they said I could use their tank,
0:05:52 > 0:05:53so this side of the tank
0:05:53 > 0:05:55represents the middle ear,
0:05:55 > 0:05:57the bit just behind your eardrum,
0:05:57 > 0:06:01and this side of the tank represents the outside world,
0:06:01 > 0:06:04and the water in the tank represents air pressure.
0:06:04 > 0:06:06There's high pressure in the outside world
0:06:06 > 0:06:08and low pressure in the middle ear.
0:06:08 > 0:06:12And this type of imbalance is really uncomfortable because
0:06:12 > 0:06:14the pressure pushes on the eardrum.
0:06:14 > 0:06:18And this is where your Eustachian tube springs into action.
0:06:18 > 0:06:19Like this.
0:06:19 > 0:06:21When you swallow or yawn, it opens up,
0:06:21 > 0:06:23allowing the ear pressure in the middle ear
0:06:23 > 0:06:25to equalise with the atmosphere around you.
0:06:25 > 0:06:28It connects your middle ear to the back of your throat.
0:06:29 > 0:06:31But don't just take our word for it.
0:06:32 > 0:06:35We're going to show you where the opening to the Eustachian tube is
0:06:35 > 0:06:38and what it looks like, using this camera.
0:06:38 > 0:06:40I'm going to put it right to the back of my mouth,
0:06:40 > 0:06:43- past the dangly a bit... - The uvula.
0:06:43 > 0:06:44..then I'll hook it over my soft palate
0:06:44 > 0:06:47and push it forwards through my noise.
0:06:47 > 0:06:49The Operation Ouch! sticker,
0:06:49 > 0:06:52that should be the opening to Xand's Eustachian tube.
0:06:52 > 0:06:54Now, we've never done this before
0:06:54 > 0:06:56and I don't know if it's going to work,
0:06:56 > 0:06:57but we're going to give it our best shot.
0:06:57 > 0:07:00We can only do this because we're doctors.
0:07:00 > 0:07:02Right, Xand, insert the camera.
0:07:02 > 0:07:05The camera's now going through Xand's mouth.
0:07:05 > 0:07:08See the lab here, it's got the camera showing back at the lab.
0:07:08 > 0:07:11Now we're right at the back of Xand's mouth
0:07:11 > 0:07:15and that, there, is the entrance to Xand's Eustachian tube.
0:07:15 > 0:07:17That is an amazing view.
0:07:17 > 0:07:19There we go, we've actually found it. Wow!
0:07:19 > 0:07:23And if I shine this light up Xand's nose, it shows you where
0:07:23 > 0:07:26the Eustachian tube is in relation to his nostrils.
0:07:26 > 0:07:27What do you think, Xand?
0:07:27 > 0:07:29XAND MUMBLES
0:07:29 > 0:07:32So now you know where it is and how it works,
0:07:32 > 0:07:34but what would happen if it wasn't there at all?
0:07:34 > 0:07:35Well, let's find out.
0:07:35 > 0:07:37To the Ouch Roof!
0:07:37 > 0:07:39It's just the roof of the lab, Xand.
0:07:39 > 0:07:40WHISPERS: Ouch Roof!
0:07:42 > 0:07:44This is an oil drum.
0:07:44 > 0:07:47Yes, but for the purposes of our experiment,
0:07:47 > 0:07:48let's call it the middle ear.
0:07:48 > 0:07:52That this bit, between the ear canal and the Eustachian tube.
0:07:52 > 0:07:55- OK, can we get on now?- Yes.
0:07:55 > 0:07:58In the bottom of the drum is some water being heated by a burner
0:07:58 > 0:08:00and being turned into steam.
0:08:00 > 0:08:02This hole in the top of the drum
0:08:02 > 0:08:04represents your Eustachian tube.
0:08:04 > 0:08:06So, with the top of the drum open like this,
0:08:06 > 0:08:09it represents what's going on inside your ear.
0:08:09 > 0:08:12The Eustachian tube is equalising the pressure inside the ear
0:08:12 > 0:08:14with the pressure outside.
0:08:14 > 0:08:19But what would happen if this middle ear didn't have a Eustachian tube?
0:08:20 > 0:08:22Well, we're going to show you.
0:08:22 > 0:08:24By putting the lid on the top of the oil drum,
0:08:24 > 0:08:26Chris is creating the same effect
0:08:26 > 0:08:29as if your Eustachian tube wasn't working.
0:08:29 > 0:08:32We're going to cool down the outside of the drum, creating an imbalance
0:08:32 > 0:08:34between the pressure on the outside of the ear
0:08:34 > 0:08:36and the pressure on the inside.
0:08:36 > 0:08:38Just like what happens when you dive down deep
0:08:38 > 0:08:40or land in an aeroplane.
0:08:40 > 0:08:43So, can you guess what will happen? Ready?
0:08:43 > 0:08:44Oh!
0:08:45 > 0:08:46LAUGHTER
0:08:48 > 0:08:49With no Eustachian tube to
0:08:49 > 0:08:51equalise the lower pressure inside
0:08:51 > 0:08:53with the higher pressure outside,
0:08:53 > 0:08:54the drum imploded!
0:08:54 > 0:08:57And that's why you need a Eustachian tube.
0:08:57 > 0:09:01And what's amazing about this is, this is a hard steel drum,
0:09:01 > 0:09:04it's not soft at all, and yet it has been completely crushed
0:09:04 > 0:09:06by the atmospheric pressure.
0:09:06 > 0:09:10So without a Eustachian tube, your body wouldn't be able to equalise
0:09:10 > 0:09:13the pressure between your middle ear and the atmosphere.
0:09:13 > 0:09:16We've shown you just where your Eustachian tube is
0:09:16 > 0:09:18and why it's there.
0:09:18 > 0:09:20Without this incredible piece of body kit,
0:09:20 > 0:09:22you wouldn't be able to pop your ears,
0:09:22 > 0:09:24equalising the pressure inside
0:09:24 > 0:09:25with the pressure outside.
0:09:27 > 0:09:28So, now that's sorted...
0:09:28 > 0:09:30I'm off to see Dave and Dolly at the beach.
0:09:30 > 0:09:32I could use a few days on holiday.
0:09:36 > 0:09:39Well, haven't we got lucky with the weather?
0:09:39 > 0:09:40You know what I fancy for dinner?
0:09:40 > 0:09:41Fish and chips.
0:09:41 > 0:09:43I mean, chips. Just chips.
0:09:43 > 0:09:46Only the chips. Chips is best.
0:09:46 > 0:09:47SIREN BLARES
0:09:51 > 0:09:53- We're both... - BOTH:- ..Ouch And About.
0:09:53 > 0:09:56I'm hitting the wards with my Ouch bleeper.
0:09:56 > 0:09:59- Have you got a question for me? - Yeah.- Wow.
0:09:59 > 0:10:02And I'm hitting the streets to answer your medical mysteries.
0:10:03 > 0:10:06In the hospital playground, Xand's in a right tangle.
0:10:06 > 0:10:08- BEEPING - Quick, that's your bleeper!
0:10:10 > 0:10:11It's from Ellie.
0:10:12 > 0:10:14She's recovering from an operation.
0:10:14 > 0:10:15Hi, Ellie, how are you?
0:10:15 > 0:10:18- Hi, Dr Xand. - Do you have a question for me?
0:10:18 > 0:10:20How did your spine keep you up on your feet?
0:10:20 > 0:10:22What's the diagnosis, doc?
0:10:22 > 0:10:23Sounds to me like a case of...
0:10:26 > 0:10:29You'd better put you back into this one, Xand.
0:10:29 > 0:10:32So your spine is made of bones called vertebrae.
0:10:32 > 0:10:36They stack up and between each one is a rubbery disc of cartilage.
0:10:36 > 0:10:38And that means your spine is
0:10:38 > 0:10:41almost like a sort of flexible, bendy pole that's quite strong,
0:10:41 > 0:10:42but that on its own won't hold you upright.
0:10:42 > 0:10:45What you need around your spine
0:10:45 > 0:10:48is all the muscles that keep it held straight.
0:10:48 > 0:10:51So if you just had muscles and no spine, you'd still flop?
0:10:51 > 0:10:53If you took out your spine,
0:10:53 > 0:10:55you'd just collapse in a heap of jelly,
0:10:55 > 0:10:57but if you took away your muscles,
0:10:57 > 0:10:59you'd just fall down like a stack of blocks,
0:10:59 > 0:11:01so you need both muscles and bones.
0:11:01 > 0:11:04Why are you interested in your spine?
0:11:04 > 0:11:07Cos I had an operation on my spine
0:11:07 > 0:11:09cos I have cerebral palsy.
0:11:09 > 0:11:11How do you explain cerebral palsy?
0:11:11 > 0:11:16The signals in my brain get muddled up and go to my legs
0:11:16 > 0:11:19so that I walk on my tippy toes.
0:11:19 > 0:11:20And did the operation fix it?
0:11:20 > 0:11:25- Yes.- You deserve an Operation Ouch! sticker.- Thank you.
0:11:25 > 0:11:27- Can you show me your walking? - Mm-hm.
0:11:29 > 0:11:30Brilliant, Ellie.
0:11:30 > 0:11:32Dr Chris is stepping out, too.
0:11:32 > 0:11:34He's on a quest for questions.
0:11:34 > 0:11:36Dr Chris?
0:11:36 > 0:11:38What is your medical mystery question?
0:11:38 > 0:11:41My question is...
0:11:43 > 0:11:44So what you're describing is,
0:11:44 > 0:11:48when the roller coasters gets to the top and you go over,
0:11:48 > 0:11:49that's when your stomach rises.
0:11:49 > 0:11:54What you're experiencing there is no gravity, so you're floating
0:11:54 > 0:11:55and it's a bit like being in space.
0:11:55 > 0:11:57It can make you feel quite sick.
0:11:57 > 0:12:01What do you have to remember when you're sick on a roller-coaster?
0:12:01 > 0:12:02You've got to be sick into the air
0:12:02 > 0:12:05so that it goes over all the people behind you.
0:12:05 > 0:12:06Yuck! Chris!
0:12:06 > 0:12:08I'm going to give you a sticker.
0:12:08 > 0:12:10Come on, Xand. Don't tell me you've never done it.
0:12:10 > 0:12:13- BEEPING - That's your next call.
0:12:13 > 0:12:15It's from Bethany, who has an infection.
0:12:15 > 0:12:16Hi, Bethany, how are you?
0:12:16 > 0:12:18- Hi, Xand. - So, have you got a question for me?
0:12:18 > 0:12:21I do. How do painkillers know where the pain is?
0:12:21 > 0:12:23What's the diagnosis, doc?
0:12:23 > 0:12:26It sounds to me like a case of...
0:12:27 > 0:12:30Ouch, that sounds painful.
0:12:30 > 0:12:33The thing about painkillers is they actually don't know where to go.
0:12:33 > 0:12:35What they do is they work all over your body.
0:12:35 > 0:12:37Now, are you taking painkillers at the moment?
0:12:37 > 0:12:39Paracetamol and Ibuprofen.
0:12:39 > 0:12:41These painkillers act both in the brain,
0:12:41 > 0:12:45where they stop pain signals being received, and elsewhere in the body.
0:12:45 > 0:12:47So wherever you have inflammation,
0:12:47 > 0:12:49you tend to get hot and red and swollen
0:12:49 > 0:12:52and the anti-inflammatory painkillers
0:12:52 > 0:12:54that you're taking are damping down that inflammation
0:12:54 > 0:12:57so it hurts a bit less while your body mends.
0:12:57 > 0:12:59- Does that make sense?- It does.
0:12:59 > 0:13:00- Here you go.- Thank you.
0:13:00 > 0:13:03- Bethany, thank you very much. Bye. - Bye.
0:13:03 > 0:13:04Job done for today.
0:13:04 > 0:13:06Clinic closed.
0:13:10 > 0:13:12Remember Tenny and her bleeding nose?
0:13:12 > 0:13:14Her bleeding knows what?
0:13:14 > 0:13:16- Her bleeding nose. - Yes, what does it know?
0:13:16 > 0:13:19You said her bleeding knows something, what is the something?
0:13:19 > 0:13:21- What does it know? - What? Her bleeding nose?
0:13:21 > 0:13:23Finish the sentence!
0:13:23 > 0:13:24Let's find out how she's getting on.
0:13:28 > 0:13:32Earlier, Tenny and her mum arrived in the emergency department with...
0:13:32 > 0:13:34..a humongous pile of tissues...
0:13:34 > 0:13:36..and one of her many nosebleeds.
0:13:37 > 0:13:41Tenny was skipping with her mates in the school playground when her nose
0:13:41 > 0:13:43began to bleed and it wouldn't stop.
0:13:43 > 0:13:44- BOTH:- Ouch!
0:13:46 > 0:13:48This isn't unusual for Tenny.
0:13:49 > 0:13:53Here's Dr Jo Stone with a plan to stop the nosebleeds for good.
0:13:54 > 0:13:58Dr Jo starts by using a spray which is a local anaesthetic.
0:13:58 > 0:14:01It's numbs Tenny's nose so she can't feel any pain.
0:14:03 > 0:14:05But it doesn't taste too good.
0:14:05 > 0:14:07Then Dr Jo gets a stick
0:14:07 > 0:14:09with a chemical on the end called silver nitrate
0:14:09 > 0:14:11to cauterise her nose.
0:14:11 > 0:14:14- Is it like a bit of a fire thing, like a spark?- No, not at all.
0:14:14 > 0:14:17Don't worry, Tenny, there's not a sparkler in sight.
0:14:18 > 0:14:23Cauterisation means to carefully burn and destroy unwanted tissue.
0:14:23 > 0:14:26The silver nitrate on the end of the stick softly burns the troublesome
0:14:26 > 0:14:28blood vessel, sealing it up
0:14:28 > 0:14:31and stopping it from ever bleeding again.
0:14:31 > 0:14:34It sounds drastic, but it's very gentle and, with the anaesthetic,
0:14:34 > 0:14:36Tenny doesn't feel a thing.
0:14:36 > 0:14:38You're all done.
0:14:38 > 0:14:39Yeah, it was not that bad.
0:14:39 > 0:14:42She shouldn't pick it, blow it, try not to sneeze too much
0:14:42 > 0:14:46and hopefully it should go back to normal within about five days.
0:14:46 > 0:14:48Hopefully my nosebleeds won't start again.
0:14:48 > 0:14:51Well, fingers crossed that's done the trick.
0:14:51 > 0:14:53- Bye!- Bye!
0:14:54 > 0:14:56Still to come...
0:14:57 > 0:14:59..Frankie's full of fun...
0:14:59 > 0:15:01Why did the chicken cross the road?
0:15:01 > 0:15:04..and Xand meets Grace and Scooby.
0:15:04 > 0:15:05Oh, hello!
0:15:06 > 0:15:08But first...
0:15:08 > 0:15:11Did you know that in your lifetime
0:15:11 > 0:15:13your mouth will produce enough saliva
0:15:13 > 0:15:14to fill two swimming pools?
0:15:15 > 0:15:16Wow!
0:15:20 > 0:15:24Amazing people do lots of important jobs inside and outside hospitals
0:15:24 > 0:15:26that help to keep you safe.
0:15:26 > 0:15:29But what will happen when we have a go?
0:15:29 > 0:15:30I feel a bit silly.
0:15:30 > 0:15:32This is Operation Takeover.
0:15:33 > 0:15:35Can you guess who today's hero is?
0:15:35 > 0:15:37Well, I'll give you a clue.
0:15:37 > 0:15:38You might have to see them if...
0:15:38 > 0:15:41You're bit hard to understand.
0:15:41 > 0:15:43That was a rubbish clue, Chris!
0:15:43 > 0:15:45We're about to take over the job of today's hero,
0:15:45 > 0:15:47dental surgeon Anitha.
0:15:47 > 0:15:49Anitha is a top trainer
0:15:49 > 0:15:52at the King's College London Dental Institute.
0:15:52 > 0:15:56Now, how important is it to look after your teeth?
0:15:56 > 0:15:59It is incredibly important to look after your teeth.
0:15:59 > 0:16:01Brushing morning and night for two minutes
0:16:01 > 0:16:04and to try and not eat too many sugary things,
0:16:04 > 0:16:05fizzy drinks especially.
0:16:05 > 0:16:08So how often should you see the dentist?
0:16:08 > 0:16:11You should really see the dentist every six months.
0:16:11 > 0:16:12- A-hem-hem.- What?
0:16:12 > 0:16:14Dr Xand is very proud of his teeth and he would like
0:16:14 > 0:16:17to show them off to you. Would you mind having a look at them?
0:16:17 > 0:16:19Absolutely, that's no problem.
0:16:20 > 0:16:21He's such a show-off.
0:16:23 > 0:16:26Here we go, Xand. Open wide!
0:16:26 > 0:16:29Right, eight, seven, six...
0:16:29 > 0:16:31If you've ever wondered what on earth your dentist is talking about
0:16:31 > 0:16:34when you're in the chair, here's how it works.
0:16:34 > 0:16:36Each tooth is given a specific number
0:16:36 > 0:16:38according to where it is in the mouth.
0:16:38 > 0:16:41Any milk teeth you still have will be given a letter.
0:16:41 > 0:16:43And what kind of common problems are you looking for?
0:16:43 > 0:16:46I'm looking to make sure that you're brushing properly
0:16:46 > 0:16:48and that there isn't any decay in your teeth.
0:16:48 > 0:16:50Xand's done very well and he doesn't have any.
0:16:50 > 0:16:53Very impressive, Xand.
0:16:53 > 0:16:55Before we're let loose on today's takeover challenge,
0:16:55 > 0:16:59we need a masterclass, but I've no idea who we're going to practise on.
0:16:59 > 0:17:01We use something very special.
0:17:01 > 0:17:04- We use a phantom head. - A phantom head?!
0:17:04 > 0:17:05Argh!
0:17:05 > 0:17:07Oh, come on, Xand.
0:17:07 > 0:17:10- Really? The phantom... - Argh!- ..or model head
0:17:10 > 0:17:13is used by students to practise doing fillings.
0:17:14 > 0:17:17You start by putting in a suction tube
0:17:17 > 0:17:20to remove any extra saliva so the patient doesn't choke.
0:17:20 > 0:17:21Next you use the drill.
0:17:21 > 0:17:23Cool.
0:17:23 > 0:17:25Attaching the drill bit with a steady hand.
0:17:25 > 0:17:26- There you go.- Clicks in.
0:17:26 > 0:17:30Then we're going to imagine that this tooth has a little bit
0:17:30 > 0:17:34of decay in it and so we're going to cut a little, teeny, tiny hole.
0:17:34 > 0:17:35In goes the filling.
0:17:35 > 0:17:37We're going to use a white filling
0:17:37 > 0:17:39material called composite.
0:17:39 > 0:17:42Which is set hard using an ultraviolet light.
0:17:42 > 0:17:46- Wow!- So we cover it so that it doesn't hurt our eyes
0:17:46 > 0:17:49and then if you touch it, it's gone completely hard.
0:17:49 > 0:17:51- Amazing.- Thanks, Anitha.
0:17:51 > 0:17:54We seen just how important dentists are for keeping your oral health
0:17:54 > 0:17:56in tiptop condition.
0:17:56 > 0:17:59But will we be able to brush up on our skills enough
0:17:59 > 0:18:01to make our careers as dentists sparkle?
0:18:01 > 0:18:03Come on.
0:18:03 > 0:18:05It's time for us to take over as dentists.
0:18:08 > 0:18:11Your challenge is to perform a filling on a phantom head.
0:18:11 > 0:18:13The first part is to remove the decay
0:18:13 > 0:18:16and the second part is to put the filling in.
0:18:16 > 0:18:20I'll be judging you on your professionalism, your technique
0:18:20 > 0:18:23and how well you make it look like a real tooth at the end.
0:18:25 > 0:18:27You know what, Chris? I've really got this challenge.
0:18:27 > 0:18:29Anitha thinks my teeth look great
0:18:29 > 0:18:31and now that I've overcome my fear of the phantom heads,
0:18:31 > 0:18:33there's really nothing to worry about.
0:18:33 > 0:18:35Oh, you've overcome your fear, have you?
0:18:35 > 0:18:36Well, this won't bother you at all.
0:18:36 > 0:18:38Argh!
0:18:40 > 0:18:44Come on, Chris. It's time to get our teeth into this.
0:18:44 > 0:18:45No problem.
0:18:45 > 0:18:47First of all, we get out the drill.
0:18:47 > 0:18:49Put that right in.
0:18:49 > 0:18:51- OK.- That's very good.
0:18:51 > 0:18:53Hello, sir or madam.
0:18:53 > 0:18:54Drill.
0:18:55 > 0:18:57- DRILL WHIZZES Oh...- Oh!
0:18:57 > 0:19:00Whoa! Health and safety, Xand!
0:19:00 > 0:19:04Before you take your eye out, press the back, goes in and locks it.
0:19:04 > 0:19:05So, first big mistake.
0:19:05 > 0:19:08So you've got to lock the drill bit into the hand-piece.
0:19:08 > 0:19:11It can fly out and then that could hurt somebody.
0:19:11 > 0:19:15It's a bit nerve-racking cos it looks so much like a real tooth.
0:19:15 > 0:19:17I kind of don't want to drill into it.
0:19:19 > 0:19:20I'm drilling already.
0:19:20 > 0:19:23What about the suction, smarty-pants?
0:19:23 > 0:19:25So, he's forgotten to turn his suction on.
0:19:25 > 0:19:26That's embarrassing.
0:19:26 > 0:19:29So if it was a real patient, they'd be gurgling.
0:19:30 > 0:19:34Erm, I'd focus on yourself rather than me, Xand.
0:19:34 > 0:19:36Oh, he's got his hands in the patient's eyes.
0:19:36 > 0:19:39We don't do that, usually.
0:19:39 > 0:19:41Come on, slowcoach. I've moved on to filling.
0:19:42 > 0:19:44Right behind you.
0:19:44 > 0:19:45I've had to use quite a lot
0:19:45 > 0:19:47and I think I may have drilled out a little too much tooth.
0:19:47 > 0:19:48Oh, Xand.
0:19:50 > 0:19:53I mean, it's very clear now why people have to train
0:19:53 > 0:19:56for years and years how to do this.
0:19:56 > 0:19:59Just need to set it with the UV light.
0:19:59 > 0:20:02Probably enough. And, right, thanks very much, sir or madam.
0:20:02 > 0:20:04You can go on your way.
0:20:05 > 0:20:08Well, I think I'm done. A satisfied customer.
0:20:08 > 0:20:10You can close your mouth now.
0:20:10 > 0:20:11Not sure he's impressed.
0:20:11 > 0:20:13Fingers crossed Anitha is.
0:20:13 > 0:20:15Time for the verdict.
0:20:15 > 0:20:17Anitha, how did we do?
0:20:17 > 0:20:20Well, you both tried really hard.
0:20:20 > 0:20:23- That's not good.- "Tried." - That is not good.
0:20:23 > 0:20:25In terms of professionalism, Xand,
0:20:25 > 0:20:28you did put your fingers in the patient's eyes.
0:20:28 > 0:20:31I needed a place to rest my hand.
0:20:31 > 0:20:36Technique-wise, Xand did take a bit more tooth off
0:20:36 > 0:20:37than we normally would.
0:20:37 > 0:20:42For the final product, actually, you were both not too bad.
0:20:42 > 0:20:43So what's the verdict?
0:20:45 > 0:20:47- Chris.- Yes!- Oh!
0:20:48 > 0:20:51I guess I wasn't expecting to lose.
0:20:51 > 0:20:53What, cos you'd had such a good time?
0:20:53 > 0:20:56I'd begun to believe that I had become a dentist.
0:20:56 > 0:20:58Well, Xand, you may have felt like a real dentist,
0:20:58 > 0:21:00but you're not a real dentist.
0:21:00 > 0:21:03That is a job most certainly best left to the professionals.
0:21:03 > 0:21:06Anitha, I think you better have our coats back.
0:21:06 > 0:21:08Fabulous.
0:21:12 > 0:21:15Your body is amazing, but sometimes it needs help.
0:21:16 > 0:21:19All over the UK, there are special teams of professionals trained
0:21:19 > 0:21:21to tackle medical mysteries.
0:21:21 > 0:21:23And not all of them are human.
0:21:24 > 0:21:28When I get ready in the morning, I barely give it a second thought.
0:21:28 > 0:21:32The task of putting on shoes and socks might seem easy to most of us,
0:21:32 > 0:21:35but to some people, this is a real challenge.
0:21:37 > 0:21:39I'm meeting 13-year-old Grace.
0:21:39 > 0:21:41Grace, how are you doing?
0:21:41 > 0:21:43Grace, like Ellie we met earlier,
0:21:43 > 0:21:45has cerebral palsy,
0:21:45 > 0:21:48a brain condition that affects muscle control and movement.
0:21:49 > 0:21:52In Grace's case, both her movement and speech are affected
0:21:52 > 0:21:56and she often needs the use of a wheelchair to help her get around.
0:21:56 > 0:21:59Hang on, was Grace texting with her toes?
0:21:59 > 0:22:00Cool.
0:22:00 > 0:22:05What do you think you fight harder to do in a day than I would?
0:22:05 > 0:22:10Anything to do with my hands, picking things up.
0:22:10 > 0:22:11Picking things up?
0:22:11 > 0:22:14Is it frustrating not to be able to pick things up or...?
0:22:14 > 0:22:17Yeah, very frustrating.
0:22:17 > 0:22:21Apparently you have a special someone who helps you do stuff,
0:22:21 > 0:22:22- is that right?- Yeah.
0:22:22 > 0:22:24Scooby!
0:22:24 > 0:22:26Oh, hello! So who's this?
0:22:26 > 0:22:28Scooby.
0:22:28 > 0:22:29Hello, how are you doing?
0:22:30 > 0:22:31Scooby isn't just cute,
0:22:31 > 0:22:34he's a professionally trained assistance dog
0:22:34 > 0:22:36whose job is to help Grace.
0:22:36 > 0:22:39After seeing assistance dogs on BBC's Children In Need,
0:22:39 > 0:22:41Grace knew that one would help improve her life
0:22:41 > 0:22:44so she contacted the charity Dogs For Good.
0:22:45 > 0:22:47Scooby helps Grace in everyday tasks.
0:22:47 > 0:22:49He can open doors...
0:22:49 > 0:22:52- Thank you.- ..pull off her socks...
0:22:52 > 0:22:56Wow! ..and look, he even helps her get out of bed in the morning!
0:22:56 > 0:22:58That's amazing.
0:22:58 > 0:23:00XAND LAUGHS So, Scooby, up, up.
0:23:03 > 0:23:05Does he make the bed as well?
0:23:05 > 0:23:08- No.- Dogs don't do that.
0:23:08 > 0:23:10Mum Simone has seen a massive difference in Grace
0:23:10 > 0:23:11since Scooby arrived.
0:23:11 > 0:23:13He is a calming presence for her.
0:23:13 > 0:23:16If she's in a bad mood, if she's come home from school in a bad mood,
0:23:16 > 0:23:19he meets her at the door and he just makes her laugh straightaway
0:23:19 > 0:23:21cos he sniffs the wheelchair for her leftover lunch.
0:23:21 > 0:23:23It's a lot of responsibility, having a dog, for a kid,
0:23:23 > 0:23:25so you're kind of forced to be a bit more independent.
0:23:25 > 0:23:28Grace will wash Scooby's food bowl, she'll wash his water bowl,
0:23:28 > 0:23:30make sure he's got fresh water every day.
0:23:31 > 0:23:35Scooby also encourages Grace to go outside and be more active.
0:23:35 > 0:23:38Has he changed how much you get out of the house?
0:23:38 > 0:23:42Yeah. Before, I would only go out
0:23:42 > 0:23:45maybe once a week.
0:23:45 > 0:23:48You'd go out of the house once a week before you got Scooby?
0:23:48 > 0:23:51- Yeah.- Wow. And now how often do you go out of the house?
0:23:51 > 0:23:52Every day.
0:23:52 > 0:23:54That's a massive difference.
0:23:54 > 0:23:55And do you feel better because of that?
0:23:55 > 0:23:58- Yeah.- Are you better at football? - Yeah.
0:24:01 > 0:24:03Scooby makes such a difference.
0:24:03 > 0:24:05He helps Grace's independence,
0:24:05 > 0:24:08he keeps her fit and he's her best mate.
0:24:09 > 0:24:11Have you got any nicknames for Scooby?
0:24:11 > 0:24:13BDF.
0:24:13 > 0:24:15BDF? What does that stand for?
0:24:15 > 0:24:17Best dog forever.
0:24:17 > 0:24:19Best dog forever?
0:24:19 > 0:24:20I think that's probably right.
0:24:20 > 0:24:23It's great to know assistance dogs like Scooby
0:24:23 > 0:24:24can make such a difference.
0:24:24 > 0:24:27It's amazing to see how helpful Scooby is.
0:24:27 > 0:24:30I wonder if he could take over from Dr Chris for a while.
0:24:30 > 0:24:32What do you think, Scoob?
0:24:32 > 0:24:33Oi!
0:24:38 > 0:24:41Unfortunately, things got on top of our next patient.
0:24:41 > 0:24:44That's right. A lot of things right on top of him.
0:24:44 > 0:24:47Luckily, he came to the emergency department.
0:24:48 > 0:24:51In Sheffield accident and emergency,
0:24:51 > 0:24:52five-year-old Frankie is waiting
0:24:52 > 0:24:54to see the doc with his dad and his nan.
0:24:56 > 0:24:58How did you get that cut, Frankie?
0:24:58 > 0:25:01One landed on my head very completely.
0:25:01 > 0:25:04What landed on your head very completely?
0:25:04 > 0:25:05And then...
0:25:06 > 0:25:08- ..crack.- Yikes!
0:25:08 > 0:25:10But what was it? Let's get the full story.
0:25:11 > 0:25:14Frankie was playing in his school playground.
0:25:14 > 0:25:16Wow, that playhouse is huge!
0:25:16 > 0:25:18- It looks awesome.- It does.
0:25:18 > 0:25:21But Frankie and his mate Harry had grand ideas of their own.
0:25:21 > 0:25:24They started to build the biggest skyscraper
0:25:24 > 0:25:27in the history of the world ever.
0:25:27 > 0:25:29It's a whopper!
0:25:29 > 0:25:32It's getting bigger and bigger and bigger...
0:25:32 > 0:25:34But as they were busily building,
0:25:34 > 0:25:37it got knocked and came crashing down.
0:25:37 > 0:25:38Oh, no!
0:25:38 > 0:25:42One of the big blocks hit Frankie on the head, knocking him over.
0:25:42 > 0:25:43- BOTH:- Ouch!
0:25:43 > 0:25:47My daddy thinks I'm crazy, but I'm not!
0:25:47 > 0:25:49I'm not even crazy.
0:25:51 > 0:25:55Come on in, Dr Robert Eastman, before these two fall out.
0:25:55 > 0:25:59- Did you hurt anywhere else on your body?- No, just my head.
0:25:59 > 0:26:01- Just the head?- Yeah, because, do you want to look at it?
0:26:01 > 0:26:04Yeah, I do want to look at it if that's OK.
0:26:04 > 0:26:05I think it's a broken bone, too.
0:26:05 > 0:26:07Well, shall I have a look and find out for you?
0:26:07 > 0:26:11Yeah, with an X-ray, then you can show it me on the screen.
0:26:11 > 0:26:14- OK.- I think we should call your Dr Frankie!
0:26:15 > 0:26:18But the other doctor in the room starts by checking the nerves
0:26:18 > 0:26:19which control his eyes.
0:26:19 > 0:26:22I need you to pull some funny faces for me.
0:26:22 > 0:26:24Squeeze your eyes nice and tight shut.
0:26:24 > 0:26:25Show me your teeth.
0:26:25 > 0:26:27That is a funny face, Frankie.
0:26:27 > 0:26:29It looks funnier than my jokes.
0:26:29 > 0:26:31You do jokes? Go on.
0:26:31 > 0:26:33Why did the chicken cross the road?
0:26:33 > 0:26:34I don't know.
0:26:34 > 0:26:37To get to the other side.
0:26:37 > 0:26:38Not funny, is it?
0:26:38 > 0:26:41Erm, it's better than Xand's jokes, that's for sure!
0:26:41 > 0:26:42Oi!
0:26:42 > 0:26:45Next, Dr Robert has a good look at that cut.
0:26:45 > 0:26:48- Does that hurt the most? - Yeah, that hurts the most.
0:26:48 > 0:26:50What's the diagnosis, doc?
0:26:50 > 0:26:52Probably don't need an X-ray.
0:26:52 > 0:26:53Your bones feel fine.
0:26:53 > 0:26:55We'll go and see the nurses
0:26:55 > 0:26:58and see if they can pop that back together for you.
0:26:58 > 0:27:01Nurse Megan Cox gives the cut a thorough wash
0:27:01 > 0:27:04and then uses special glue to seal it up so it mends properly.
0:27:04 > 0:27:06Done.
0:27:08 > 0:27:11And now this is the end of being on TV.
0:27:11 > 0:27:13We miss you already, Frankie!
0:27:13 > 0:27:14- BOTH:- Bye!
0:27:16 > 0:27:19Next time on Operation Ouch!...

0:27:44 > 0:27:46Wait for me, Chris!
0:27:48 > 0:27:50- Hi, Bethany, how are you?- Hi, Chris.
0:27:50 > 0:27:52- It's Xand.- Oh, hi, Xand!
0:27:52 > 0:27:54LAUGHTER
0:27:54 > 0:27:56Ahem!
