good afternoon everyone my name is
and I'm really glad and honored to be
with you this afternoon my presentation
or talk let's say and is entitled
technology and the future of dental
practice
I was trained to become a dentist in the
mid 90s and during that period we didn't
have PowerPoint presentations or it was
really limited and not all professors
used it we used to have overhead
projectors with hand-drawn or hand
written slides does any one of you know
what an overhead projector is
not really not many so you guys are
younger than I thought so an overhead
projector is something that looks like
this okay so this thing was really
primitive and limited and it did not
convey the message really easily so this
made the learning and teaching both
difficult nowadays and due to technology
things are a lot different now our
students can watch videos on YouTube
instead of having to hang up around the
professor to watch him demonstrate on a
tiny tooth the professor can also do the
demonstration and have a camera filming
what he's doing and how it projected on
the screen and students can watch to
watch it really easily and pay attention
to different types of details these
technological advancements as I said
have made both teaching and learning
really much easier year now Dentistry is
not separated from all of this
technological advancements have made a
revolution in the dental practice
I remember when I graduated in the 1999
I was trained using the same equipment
that my parents were trained on during
the 60s and 70s of the past Century
but with a slightly different design
let's say but the equipment were
basically the same but after that and
during the 2000 years things have taken
a different perspective and
technological advancements have made a
revolution in the dental practice let's
say new technologies and new materials
and new methods
technological advancements in dentistry
could be seen in their diagnosis and
treatment of dental issues the design
and execution of different dental
procedures and the transitions from
traditional techniques to more modern
technological Alternatives and also they
have revolutionalized dental research
which also helps in the development of
the dental profession and dental
practice
I will start by the simple thing which
is the use of an intra-ordal camera
although these technological
advancements are not yet widely
available in all dental clinics or
institutions because they are still they
still have a high cost but they have
made the practice of Dentistry much
easier and we are hoping and looking
forward that the prices would go down in
the near future and they would become
widely available in all the dental
practices and institutions let's go back
to what we started with the intraoral
camera the intraoral camera is a small
device that the dentist can use it
inside the patient's mouth and this
intra-oral camera would show the patient
on a computer screen in front of him the
issues that he has with his teeth with
his gums and the treatment were the
dentist would
like explain to the patient the dental
procedure that he's going to do and also
the patient can follow up the uh the
advancement in the dental treatment that
he's being provided by the by the
dentist also another method of diagnosis
that has um that has witnessed A
revolution is the intra the dental
radiography in the past we used to do
radiographs using those films those
films are a lot cheaper than what we use
nowadays and but the procedure is much
more difficult because you would have to
put the film take the radiograph take
the film to a dark room and then process
it
and then it's about five to seven
minutes until you can figure out whether
your X-ray was correct whether you've
captured the required details and
whether it had the the sharpness that
you wanted it to be as opposed to the
digital radiographic sensors where you
put it inside the patient's mouth you
take the radiograph and then it's
directly projected on the screen the the
X-ray is really sharp well defined and
the details are very very nicely shown
on the screen you can enlarge you can
make it smaller you can do all sorts of
measurements on that so it has made the
diagnosis much easier and quicker and
then the exposure the X-ray exposure is
a lot less than the the radiographs that
we used before so it is much it's less
risky to the patient and the dentist as
well however it has some drawbacks and
the first one of them as all other
technological advancements it's much
more expensive as a digital sensor would
cause a few thousand JDS those a whole
pack of the older films would cause
maybe 10 JDS or something like that and
sometimes you would need more than one
size of a sensor to be able to use it in
different parts of the mouth and also
this sensor is made of rigid plastic so
sometimes it's not easily adaptable to
all parts of the oral cavity
another advancement in Dental
radiography which has also helped in in
the easily diagnosis and the um the
execution of dental procedures is
something we called con beam computer
tomography it is a special type of CT
scans I think you all have heard about
the CT scan so it takes sections and the
3D image of the whole thing so it shows
more details of the teeth and the
surrounding tissue and the uh the bones
also instead of having a 2D image of the
oral structures
and it is nowadays widely used in root
canal treatments and also in planning
and executions different types of
surgeries such as the extraction of
wisdom teeth and planning of dental
implants because it allows us to have as
we said a 3D detailed and accurate image
with lower radiation than the regular
cities and as we can see over here that
we can do some measurements of the bone
height as well as it shows us also the
bone width over here which cannot be
seen in regular radiographs so this is a
very uh good instrument that or a
diagnostic tool but again it is more
expensive a regular radiograph would
cost a patient to pay like 10 JDS
whereas this one might be up to 50 JDs
and it's not widely available in Dental
Clinic and in a radiographic centers as
well so it's still Limited
Now we move to another example which is
really my area of expertise because it
is my specialty which is the uh the
fixed and removable prosthodontics I
think that you all know what a crown or
a bridge is either you have one or you
went with your parents or with your
friends to a dentist to have one okay so
in the past
when you go to the dentist
you go and take the dentist would finish
preparing your teeth then he will start
by taking an impression of your teeth
okay to get a negative replica which
would be sent later on to the lab poured
into a model and then the model would be
worked on by a dental technician who
would start mixing the materials and
then building up the prosthesis and then
baking it finishing it and sending it
back to the dentist to put it inside the
patient's mouth this procedure is called
the manual workflow and it's still
widely used in institutions and in
clinics we even our students learn to
use it in the at the University of
Jordan but as opposed to this one where
a lot of inaccuracies come all over the
way from taking the impression into
pouring it into the lab which depends
highly also on the manual skills of the
technician we have another newer thing
that is also crawling its way into the
dental profession and starting to become
more and more used which is the digital
workflow again we go back to this
intraoral camera which can capture the
same impression that we were talking
about before and it is projected on the
screen as we can see over here
okay so this is equivalent to the
impression in the manual workflow
so it takes the details of the teeth the
surrounding structures
and after we are done with that we send
this to our lab the lab would have the
same software it would start building up
the uh the prosthesis on the software
and this is called computer aided design
computer aided manufacturing or as we
call it in dentistry the cat cam
technique or the digital workflow it
allows us to get really precise
prosthesis and as I said it uses digital
Impressions and models now the lab is
looking at it he's designing the the
prosthesis he sent it back to us via
email or Whatsapp or whatever the
dentist can look at the final prosthesis
the size the shape the color the
everything he can make sure that
everything is okay then the lab would
send this to a milling machine or
printing machine that would do the whole
prosthesis and then they take it out of
the machine and they send it to the
dentist so no humans are involved in
there it doesn't depend on the humans
technical skills or abilities so we have
less errors in that and more precise
prosthesis again this is a a very uh
nice way to perform crowns and bridges
however it's not widely available
because the intraoral camera would also
cause around 15K or something like that
besides the software and it's still
limited to certain clinics and certain
labs and we still rely more on the
manual workflow however I believe that
in the near future things would turn to
the digital workflow prices would go
down like everything else in the world
like the prices start high and then they
start going down because it starts to
become widely available for everyone
another example is also the use of
lasers the use of lasers has made also
the uh the dental practice the surgery
is much easier and more convenient to
the patients it is widely used in gum
surgeries and teeth whitening and the
removal of bacteria and tooth Canal
treatments and also in taking biopsies
they are less invasive more comfortable
to the patient and more precise again
the coast is a little bit High however
those lasers are more widely used than
the other techniques like the cat cam
um as I spoke about it a little bit a
while ago they are more used than the
cat cam in surgeries and by dentists
virtual reality
so I bet you all know better about
virtual reality than I do but it's also
used in dentistry it's the creation of
interactive simulations it is beneficial
to show the patient or simulate the
procedure for the patient to decrease
his anxiety and also it is a way where
the students can train and practice the
dental procedures in a controlled and
safe environment unfortunately virtual
reality for Dentistry is not available
in Jordan until now and also it's not
really widely available in in in the
whole world it's only limited to to
institutions and to teaching Dental
students that's all because of course
obviously of the high cost of this
technique
and last but not least I'm gonna talk
also about artificial intelligence you
are also more familiar than artificial
intelligence and how it works more than
I do but nowadays it's really a hit in
dentistry and it's widely used in Dental
research and it gets a lot of citations
for publication so anyone interested
let me know I have an idea and I'm
working on that
so it uses algorithms to analyze patient
information and it can detect patterns
and identify potential issues usually
what we use is photographs x-rays or
patients histories
now for photographs it was there's a lot
of research about taking photographs
from inside the oral cavity of patients
with normal tissue oral premalignant and
cancerous tissues this is better
actually than taking biopsies because
it's less invasive it doesn't cause
patient discomfort and sometimes inside
the oral cavity the the human eye can
miss certain details sometimes we cannot
distinguish between the normal tissues
and oral premalignant tissues but as for
the artificial intelligence it does and
a lot of cases it's it's with high
accuracy we can also use it in a dental
radiography in the detection of dental
caries or or periapical lesions and also
it is it is also used in Orthodontics in
periodontics and in a lot of dental
disciplines nowadays and as I told you
it's some it's really a hit for research
nowadays for dental research so
as we all know like the future is for
the technology and it's scrolling its
way into the dental practice as well
hopefully prices would go down so that
we would be able to use it on a wider
base than what we do nowadays and thank
you all for listening
