Caption: [Music] hi guys welcome back so today I will be speaking about how what what we dentist do when we make a filling or um at least at least what I do and not all dentists do this but I think they should yeah so let&#39;s dive right into it so this case right here for example we&#39;re I&#39;m going to take different cases so this is just for illustration purposes okay so you take a look at this this picture right here so this tooth this is a Moler right this is the upper upper left yeah second quadrant so this is uh what you see here the black thing here this is a cavity this is Caris it&#39;s quite big and you can see it&#39;s almost getting into the nerve which is here see the black thing here is it better if I do this I don&#39;t I don&#39;t know if you can see the mouse uh here the mouse pointer so the black thing here so it was it has one two and three roots and this cavity is getting close to the nerve oh yeah so what do you do what do we do well usually um a lot of patients wants wants anesthesia so we put that first right make sure that the patient is numb and can&#39;t feel pain it&#39;s quite good I love that invention oh my God but what else then I usually put on this now this this is a rubber Dam you can see the blue thing here and we punch we make some holes for however many teeth we need and the teeth goes through the holes and this makes sure that the uh the work area here is completely dry we have full control usually not always but usually it&#39;s very nice when you when you remove for example um an amalgam filling cuz it&#39;s better that you don&#39;t swallow or breathe in the the amalon right yeah so usually when we drill away the uh the amalgam this area is completely black looks horrible yeah imagine getting that into your your system disgusting so it looks probably kind of awkward kind of uncomfortable but usually patients think it&#39;s ah this is pretty nice no water for me and yeah like I said we have 100% control over uh there&#39;s as you can see there&#39;s no blood there&#39;s no Ginger um um fluids coming and yeah this this is this is perfect I love using this rubber Dam right here love it what else as you can see imagine you have um imagine you have a a cavity like this look at that so this is also a molar this is the lower left and this black right here this is the cavity right this is the cavity here are the gums or more fancy the gingera yeah so the lower jaw here is what we call the mandible imagine working on this cavity right here and you need it to be dry how on Earth are you going to keep this area dry without a rubber Dam right so but take a look at the difference for example when we start drilling here uh of course this patients this patient also gets anesthesia right but imagine drilling here under the gum now this will start bleeding and you will have fluid from from the gingera from the sulcus and you will have as you can see here the saliva the spit saliva from the patient right so how on Earth are you are you going to keep this under control when you need when you put the filling you want it to be completely dryer or else it will be like I don&#39;t know standing outside painting painting the walls and it&#39;s raining that&#39;s not GNA yield a a good result no that&#39;s going to be horrible but but this is the same tooth the same tooth look at the control right so the uh the dentist put on the rubber Dam started drilling this is when his is done drilling right look at the control there&#39;s no blood there&#39;s no fluid coming from the gingera there&#39;s no spit no saliva look at that he has 100% control yeah you can see the white thing here this is Teflon tape you have heard about Teflon tape usually um plumbers use teflon tape for things I I have no idea what they do yeah but Teflon tape because Teflon it doesn&#39;t like water so it it will uh help complete the uh the isolation yes so now the tooth is ready to uh be filled get a filling now you don&#39;t want to use an amalgam filling no amalgams are horrible NS will expand and they probably will damage your too oh yeah so use we uh I usually almost always use composite that&#39;s plastic I&#39;m pretty sure that plastic isn&#39;t that healthy either but there&#39;s nothing else we can use well we can use Ceramics but um it&#39;s super expensive and the this is cheap and relatively fast yes so here has a clamp which metal here helps keep this this rubber Dam in place all right so next step now maybe I I&#39;m guessing this dentists dentist also used something that&#39;s called carriers detection die I will show you what that is so here here&#39;s another case an other teeth okay the patient or the I&#39;m sorry the dentist has drilled to get to to the carries so what what are we looking for well we&#39;re looking for the soft areas because you know tooth is supposed to be hard so usually the the areas uh inside here where you have Carris are soft but you don&#39;t want to remove too much so how can you fix that well you can use Caris detection die you see the red thing here let&#39;s play this this is car&#39;s detection die so this D you you scrub it in all over the work area and then you rinse rinse it away use water and rinse it away the areas that are still red afterwards those areas have carries or they&#39;re just unclean maybe they have black or calculus yes so this is a more controlled way of removing removing um carries making the tooth clean because some areas on a tooth some areas in here might be a little bit soft right then the dentist might think hm it&#39;s soft well I will drill I will drill even more but if the area let&#39;s see here so let&#39;s say this area as you can see it&#39;s not red not red at all so this area is clean this area it&#39;s a little bit dirty but it&#39;s very very very close to the nerve to the pulp and we don&#39;t want to perforate into the pulp no CU there&#39;s a I think when I started the the studies said that okay then you have a 70% chance of having to do a root canal on the tooth will be in infected and if you can avoid infecting the nerve that&#39;s good if you can avoid a r Canal therapy that is very very good yeah and by the way I I hate doing R canals I hate it Jesus Christ anyway so here you can see it&#39;s almost 100% clean you don&#39;t want to clean if it&#39;s very the cares is very deep the cavity is very very deep close to the nerve you usually leave some Infected Dentin uh near the nerve and you make sure that around as you can see here around it&#39;s 100% clean is there anything else I should mention well I don&#39;t want to make a super long video so this will be just the gist of everything right okay so you have cleaned the tooth you are ready to uh put the filling first thing you do you etch can see the blue uh fluid should we call it fluid blue Ed here this is actually to make the Surface a little bit surface area a little bit bigger and it will also remove because when you&#39;re drilling when you&#39;re drilling uh you throw around small particles super small particles now this this edge here will remove those as well so you etch and after etching is putting on the bonding agent so the bonding agent is the um the fluid that will the glue let&#39;s call it that yeah let&#39;s use simple words well simple the the glue will stick to the tooth and make sure that uh that the filling the composite will stick to the tooth also so it&#39;s kind of a hybrid layer afterwards you start building the tooth with composite uh but there&#39;s also other steps but I don&#39;t want to make this video into a 20 30 minute long long video so there are other steps you you you take also to make sure that the filling um is bonded well because composite unlike amalgam so amalgam will expand but composite will shrink a little bit so you have to make sure that it doesn&#39;t shrink too much how do you do that well you you make sure some okay some angles of the tooth is not straight or there a lot of things but one of the biggest things are if this is the floor uh inside the tooth you start building layers small small layers incrementally building up the tooth the the bigger layer you put of composite the more it will shrink so tiny tiny uh layers so you put one layer then you make sure that uh what is the word light cure it yeah put one layer then you light cure it as you can see here difficult to to uh to see but this thing right here it light cures the The Filling makes the filling hard and stick to the tooth okay uh so when you&#39;re done with that you uh can see here you finish the filling you make sure that it fits in the bite in the bite and that it looks good yeah and also makes you make sure we or we we make sure that um it feels smooth it doesn&#39;t have any unevenness or hard edges yeah and make sure that it all it&#39;s completely rounded all edges are supposed to be rounded it&#39;s not supposed to be a hard Edge no cuz in here here it&#39;s a big chance of a fracture when you bite down which yep so round off all edges all edges very important and yeah and the patient is done and the anesthesia will probably last for um 1 hour two or three more and the you pay okay and go home yeah I have to edit this video now I&#39;m pretty sure it will be very chaotic I should have I should have made a a manuscript actually but it is what it is so well we&#39;ll see we&#39;ll see how it turns out so thank you guys thank you for watching thank you for listening and I will see you guys in the next video all right bye-bye [Music] la
