Oral Pathology Studying Oral Cancers, Tumors, Cysts for Dental Hygiene Students.
Watch on YouTubeVideo summary
The video provides a strategic overview of oral pathology specifically designed for dental hygiene students preparing for board exams, emphasizing that reading an entire textbook is unnecessary as only specific high-yield topics will appear on the test. The primary focus is distinguishing between benign and malignant conditions, with squamous cell carcinoma identified as the most common malignant neoplasm in the oral cavity. Students are advised to memorize key risk factors such as tobacco and alcohol use, noting that their combination significantly increases cancer risk compared to either factor alone. Additionally, learners must understand where these lesions typically occur within the mouth rather than on external structures like the nose or neck, with common sites including the ventral surface of the tongue, floor of the mouth, soft palate, tonsil area, and retromolar region.
A significant portion of the lesson is dedicated to differentiating between various white and red oral lesions that often appear in case studies. The instructor highlights leukoplakia as a non-rub-off white patch caused by epithelial thickening, while contrasting it with erythroplakia, which presents as red patches and carries a higher likelihood of being malignant. Other benign conditions discussed include verruca vulgaris (warts) caused by the human papillomavirus, characterized by a rough, cauliflower-like surface; condyloma acuminatum, also viral but sexually transmitted; irritation fibromas resulting from chronic trauma like cheek biting; and inflammatory papillary hyperplasia specifically associated with denture wearers. The video further clarifies conditions related to dentures, such as epulis fissuratum which forms along the edges of a prosthesis, and pyogenic granulomas, which are red, injury-responsive growths common in children and pregnant women due to hormonal changes or plaque accumulation.
The summary concludes by addressing cystic lesions, infectious diseases, and inflammatory disorders that frequently test student knowledge. Students must distinguish between mucoceles caused by ruptured salivary ducts, ranulas located specifically on the floor of the mouth, gingival cysts found in the mandibular canine premolar region, and epidermoid dermoid cysts also seen in the oral mucosa. The transcript lists numerous infectious agents requiring identification, including Candidiasis, Herpes simplex, Varicella-zoster (shingles), Hand-Foot-and-Mouth disease, and others like measles and mononucleosis. Furthermore, the video stresses the importance of recognizing specific inflammatory conditions such as lichen planus, pemphigus vulgaris, lupus, canker sores, and erythema multiforme. Finally, it reinforces the need to differentiate clinical signs like macules, melanomas, white spongy nevus, leucoedema (a gray-blue opacity limited to the inner cheeks or lips), geographic tongue, hairy tongue, nicotine stomatitis, Fordyce granules, and median rhomboid glossitis, ensuring students can accurately diagnose based on location and appearance.

>> Let's go through oral pathology. So, I'm
going to talk about the types of oral
pathology that are commonly on the exam
and what you have to know. You do not
want to read your entire oral pathology
textbook. It's extremely confusing and
not even half of it, even less than half
of it is going to be on the board exam.
So, follow along, study with me and I'm
going to help you. So, I'm going to go
over things like geographic tongue,
hairy tongue, do you know the
difference? Leucoedema, nodules,
macules, what's the name for a wart,
things like that. So, let's just jump
right into it like I always say and
let's get some studying done. Now, if
you're a board exam prep academy member,
you have this full study guide inside
your modules. Go to your oral pathology
modules, you will see this study guide
plus pre-recorded videos, you will see
mock exams, case studies and if you are
a VIP member, you will even see
workbooks. There's the master book for
you on oral pathology, all of that. So,
if you're looking to study for the board
exam, definitely become a board exam
prep academy member. Anyway, okay, so
let's continue on here. So, what I want
you guys to know about, let's say oral
cancer lesions and different types is
definitely know squamous cell carcinoma,
okay? Know this one because it's the
most common malignant neoplasm of the
oral cavity. So, remember, do know the
difference between malignant and benign.
Benign means non-cancerous, malignant
means it is cancerous. So, typically
when we're talking about squamous cell
carcinoma, the risk factors are going to
be tobacco and alcohol. Tobacco and
alcohol together is kind of like a
double whammy, a greater risk factor
than if it was just tobacco or just
alcohol. So, for every oral pathology
that I'm going to point out to you
today, you do need to know the risk
factors and where it commonly occurs and
of course what it is. So, if in the case
study they're talking about squamous
cell carcinoma, you are going to need to
remember that it is malignant, not
benign. What are the risk factors
because in the case study they're going
to be talking about the risk factors
that could be there, but also where it
commonly occurs. Now, here for example,
it says occurs on the ventral surface
and lateral surfaces of the tongue,
floor of the mouth, soft palate, the
the like tonsil area, and the retromolar
area. Now, I don't expect you to
memorize all of that, but instead what I
want you to focus on is to think, "Okay,
it's commonly inside the mouth." Okay?
It's not going to be commonly on the
nose, or it's not going to be commonly
on the neck. It's more commonly inside
the mouth. You can memorize all of those
locations if you want to, but I find
that just might be a little bit harder.
Another one is leukoplakia. So, the key
about this one is it cannot be rubbed
off. Some of them you can rub off, but
not leukoplakia, and these are white
lesions. So, this is when the epithelial
lining is going to thicken and then
there's changes in the connective
tissue. So, leukoplakia is typically
like white patches. Now, it doesn't say
so here, but it does say it further
along in the study guide, but the common
areas are going to be inside the cheeks
and on the tongue. But what's the
difference between leukoplakia and
urethral plakia? So, urethral plakia is
going to be red, okay? And more likely
to be malignant, not benign. So, that's
a key point to know there.
Now, when we're going through benign
tumors, remember the difference between
malignant and benign. Benign is
non-cancer causing. You want to know
what verruca vulgaris is, okay? This is
caused by the human papilloma virus, and
it does have a certain look to it.
There's a broad base. It's going to be
rough, white, and a warty surface. So,
this is what a wart is, verruca
vulgaris. I do have pictures inside the
board exam prep the board exam prep
academy to put everything together for
you, but you don't need that if you
don't have it at this moment. So, think
right now, okay? As you're As you're
studying with me, do you know what
verruca vulgaris is? Can you picture it,
or do you need to quickly look it up
online? You can do that, too. Or, if
you're a board exam prep academy member,
it's even easier to look at it there.
But, what I forgot to mention was a
papilloma. They love to ask about what
does a rough, white, cauliflower-like
surface What is that? It's a papilloma.
So, it's benign, not malignant, and it's
quite firm, okay? So, anytime it talks
about a cauliflower-like surface,
papilloma. If they're talking about a
wart, verruca vulgaris.
Um con-
These are hard to pronounce. Condyloma
acuminatum.
This is going to be a warty soft tissue.
Here, I'm just going to highlight that.
Um caused by the human papilloma virus,
again. It's It's um sexually
transmitted, often with multiple
lesions. So, for this one here, if
they're talking about a sexually
transmitted disease, this could be one
of the answers. Condyloma acuminatum is
the answer there. So, you do need to
know what causes it. Not all lesions, as
you know, are sexually transmitted, but
some of them are. So, you need to know
the difference. Another common one here
is a irritation fibroma. This just means
if something's being constantly
irritated, it could cause a fibroma, to
be more specific, an irritation fibroma.
So, this is typically going to be firm.
You can kind of like palpate it, and
again, it's firm, but it's also kind of
movable a little bit, and it's most
commonly found on the buckle and labial
mucosa, okay? So, on the lips, inside
the cheek. So, a common thing that I've
seen is when somebody's cheek biting and
there's a bump on the inside of their
cheek their um cheek, it's considered an
irritation fibroma. So, that's kind of
putting critical thinking together.
Where would you see it? Somewhere where
there's constant trauma. If somebody's
chewing their cheek or the inside of
their lip, that's a very good example.
Now, what about an inflammatory
papillary hyperplasia? So, this is an
overgrowth of epithelial and fibrous
connective tissue, again, due to chronic
irritation, but specific to a denture.
So, in a case study, if the patient has
a denture, then you might think, "Okay,
there's a bump there. There's an
irritation. I'm going to call it an
irritation fibroma." But, no, that would
be the wrong answer. Because to be more
specific, when we're talking about
dentures, it's the inflammatory
papillary hyperplasia, okay?
So, see how again, we're putting things
together, where um
we're putting it together. We're
practicing critical thinking. Now, what
about epulis fissuratum?
This is also regarding a denture, but
more specifically
along the edges of the denture. It's
going to appear as an enlargement in the
vestibule, which is kind of like the
inside here, often with a fissure
corresponding to the denture um um
flange flange flange area. So, both of
them have to do with dentures, but this
would be specific to along the edges,
okay? Another big one, you guys, is
pyogenic granuloma. Also in response to
injury, but it's more common, um, along
the attached gingiva. I was going to say
along the gum line, but that's not true.
It's specific to the attached gingiva or
interdental papilla. Common in children
and pregnant females. Now, in children,
it's also because of hormones. Children
are growing, so there can be hormones
there, or it could be simply to an
irritation or injury. In pregnant
females, it's usually due to hormones
and/or if there's too much plaque in one
area, there's a lot of hormones
happening, but also too much plaque,
that could be a pyogenic granuloma. It's
a very, like, red, angry-looking
granuloma, okay?
So, moving on here, definitely know the
difference between a mucocele, a ranula,
a gingival cyst, and a and the
epidermoid dermoid cyst, okay? So, the
mucocele is going to be when a salivary
gland duct has ruptured. It's actually
more common than you think, typically
the floor of the mouth, um, blue or
purple to normal in color. So, it might
be a normal color, but it's quite a
large enlargement. Or a ranula is the
same thing as a as a mucocele,
but it's on the floor of the mouth. So,
not, you know, in the cheek or anywhere
else, but it's the floor of the mouth. A
gingival cyst is the gingival anterior
area to the first molars. Specific the
mandibular canine premolar region, so
know that. In a case study, if they're
talking about a cyst that's in the
mandibular canine premolar region, then
you know exactly which cyst it is, and
they love to talk about that one. The
epidermoid dermoid cyst, most commonly
seen in the skin and oral mucosa,
specifically the floor of the mouth. So,
see how all of these cysts kind of sound
similar,
but they're different in their own way.
Candidiasis,
herpes simplex,
varicella, which is chickenpox, herpes
zoster, shingles, hand, foot, and mouth
disease, herpangina, infectious
mononucleosis,
and measles. You need to know all of
those. They're absolutely on the board
exam. Now, lichen planus, erosive lichen
planus,
pemphigus vulgaris, bullous pemphigoid,
lupus, canker sores, and erythema
multiforme, you also have to know all of
those. You have to know ulcers, the the
differences between ulcers and fibromas,
hematomas, and petechiae. You need to
know those. Oh, and ecchymosis. So, for
example, petechiae are pinpoint areas of
hemorrhage, whereas ecchymosis is a
bruising. So, if you think of a bruise,
you don't think of it being a pinpoint,
right? It's kind of over a larger area.
So, you need to know the differences.
So, just to give you a little quick
study lesson. As you can see, I'm not
going all
over all of them, cuz that would take
several hours, but if you want me to,
you definitely want to sign up for the
Board Exam Prep Academy, cuz I have that
class in there. But, you also need to
know macules, melanomas, white spongy
nevus, leucoedema.
You need to know the difference between
leukoplakia, we talked about that
earlier, and leucoedema. Leucoedema is
different, cuz it's kind of like a
gray-blue opaque area. Leukoplakia is
white.
Leukoedema is always on the inside of
the cheek or the inside of the lip,
nowhere else. Where leukoedema
leukoplakia could be the tongue, cheek,
lips, and other areas.
Hairy tongue, geographic tongue,
nicotine stomatitis, Fordyce granules,
median rhomboid glossitis. All of those
you have to know. Now, I have a quick
review here, too, where if you're like,
"Okay, I've studied all of them. I'm
going to go through these names to see
how much I remember." That's the perfect
way to do it. And guess what? There's
more. There's practice questions. Now,
if you're not a member of the Board Exam
Prep Academy, you can have this study
guide. You can purchase it separately if
you want to. I can leave the link for
you guys down below. But, if you're a
member of the Board Exam Prep Academy,
it's already included. So, if you're
considering purchasing the study guide,
you might want to look at becoming a
member of Board Exam Prep Academy member
instead because there's more in there
for you. But, I'll leave the link for
you down below for this study guide plus
the link on how to become a Board Exam
Prep Academy member, if you like. My
