INTRODUCTION
The oral mucosa is, in many ways, similar to the skin in its architecture, function, and reaction patterns. This section only emphasizes those characteristics of the oral mucosa that influence or result in a distinct group of pathologic entities.
Because of its location at the entrance of the digestive and respiratory tracts and its proximity to the teeth, the oral mucosa is subjected to numerous natural and man-made xenobiotics. The peculiar architecture and absorption characteristics of the oral mucosa, especially in areas of extreme thinness, coupled with the rich microorganism flora of the mouth, makes the oral mucosa a peculiar site deserving separate discussion.
Cornea is the clear front surface of the eye. It lies directly in front of the iris and pupil, and it allows light to enter the eye.
Cornea forms the transparent and anterior 1/6th of the external fibrous coat of the globe of the eyeball.
The cornea is the eye's most powerful structure for focusing light that provides approximately 65 to 75 percent of the focusing power of the eye.
The cornea has unmyelinated nerve endings sensitive to touch, temperature and chemicals; a touch of the cornea causes an involuntary reflex to close the eyelid.

Keratinized and Nonkeratinized epithelium
Nonkeratinocytes
The term mucous membrane is used to describe the moist lining of the gastrointestinal tract, nasal passages, and other body cavities that communicate with the exterior. In the oral cavity, this lining is referred to as the oral mucous membrane, or oral mucosa. At the lips the oral mucosa is continuous with the skin; at the pharynx the oral mucosa is continuous with the mucosa lining the rest of the gut. Thus the oral mucosa is located anatomically between skin and gastrointestinal mucosa and
shows some of the properties of each.

Introduction
A sound knowledge of the anatomy of the periodontium and the surrounding hard and soft structures is essential to determine the scope and possibilities of surgical periodontal procedures and to minimize their risks.
Blood vessels, and nerves located in the vicinity of the periodontal surgical field, are particularly important during various surgical procedures.
Arterial Supply
Common Carotid Artery
Carotid Sinus & Carotid Body
Applied Anatomy of CCA
CAROTID PULSE :
CCA may be compressed against the carotid tubercle of transverse process of C6 vertebra about 4cm above the sternoclavicular joint.
External Carotid Artery
Generally it lies anterior to the Internal Carotid Artery.
It is the chief artery of supply to structures in the front of neck, oral cavity and in the face.
In carotid triangle
Crossed superficially by:
Cervical branch of facial nerve
Hypoglossal nerve
Facial, lingual &superior thyroid vein
Deep to artery lies:
Wall of pharynx
Superior laryngeal nerve
Ascending pharyngeal artery
Above the carotid triangle
ECA lies deep in the substance of parotid gland
Branches
Lingual Artery
Principal artery of tongue.
Arises anteromedially from ECA opposite the tip of greater cornu of hyoid bone.
Divided into three parts by hyoglossus muscle.
Applied anatomy
Sublingual artery injury occurs in premolar & molar region, when sharp instrument or rotating disks slips off a lower molar & injure the floor of mouth.
Sublingual and submental arteries may course anteriorly in close proximity to the lingual plate, and branches of these blood vessels enter accessory foramina along the lingual cortex.
Hofschneider et al (1999)
Inadvertent penetration through the lingual cortical plate into the floor of the mouth while preparing an osteotomy can cause arterial trauma, thereby resulting in development of a sublingual or submandibular hematoma
Flanagan D. et al.2003
Facial Artery
ORIGIN: Arises from the ECA just above the tip of greater cornua of hyoid bone.
COURSE:
Runs upwards in neck as cervical part ;
On face as facial part.
Tortuous course—
In neck allows free movements of pharynx during deglutition,
On face allows free movements of mandible , lips, & cheek during mastication & facial expressions, escapes traction & pressure during movements.
Cervical part :
Cervical part runs upwards on superior constrictor of pharynx deep to the posterior belly of digastric.
It grooves the posterior border of submandibular gland, makes S-bend [2 loops]
1st winding down over submandibular gland &
then up over the base of mandible.
Facial part:
The vessel enters the face by winding around the base of the mandible, and by piercing the deep cervical fascia,at the anteroinferior angle of the masseter muscle, here it can be palpated & is called as anaesthetist’s artery. Using contracted masseter as a landmark, pulse of facia

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2. Objectives
At the end of the lecture student should understand-
Keratinocytes and non-keratinocyte cells,
Junctions of oral mucous membranes,
Gingival sulcus and dentogingival junctions.
www.indiandentalacademy.com
4. Epithelial cells that ultimately keratinize are called
keratinocytes.
The epithelium contains a smaller group of cells
that do not possess cytokeratin filaments & so
they do not have the ability to keratinize. They are
known as non-keratinocytes.
www.indiandentalacademy.com
5. At ultrastructural level they have been identified
as
- Melanocytes
- Langerhans cells
- Merkel cells
- Inflammatory cells
All Except Merkel cells lack desmosomal attachment
Lack tonofilaments too and don’t take part in
maturation.
www.indiandentalacademy.com
6. Non Keratinocytes
Do not show mitotic activity
Do not undergrow maturation
Do not arranged in layers
Do not attach with adjacent keratinocytes by
desmosomes
Dendritic & appear clear in routine H& E stained section
Migrate from neural crest cells
www.indiandentalacademy.com
7. Melanocytes & Pigmentation
Endogenous pigmentation by Hemoglobin & Melanin.
Melanin produced by melanocytes situated in basal
layer.
Arise from neural crest ectoderm & enter the
epithelium at about 11 wks of gestation
Melanin synthesized by melanocytes in the form of
melanosomes.
www.indiandentalacademy.com
8. Melanophages may be seen
in CT
Commonly pigmented areas
gingiva, buccal mucosa,
palate.
Nevus, Melanoma.
Exogenous pigmentation by
Amalgam, lead, bismuth etc.
Burton’s line
www.indiandentalacademy.com
9. Langerhans cells
Dendritic cell seen in
suprabasal layer.
Lacks desmosomal attachment
Ultrastructurally presence of
rod or flask shaped granule
known as Birbeck granule.
www.indiandentalacademy.com
10. Appear at same time as melanocytes
Move in & out of epithelium
Source is bone marrow.
Immunologic function
www.indiandentalacademy.com
11. Merkel Cell
Situated in basal layer
Non dendritic
Few tonofilaments & occasional desmosomes
Characteristic presence of membrane bound
vesicle in the cytoplasm.
Have a sensory function &
respond to touch
www.indiandentalacademy.com
12. Inflammatory cells
Lymphocyte most frequent cell
PMN’s & Mast cells may also be present.
Associated with langerhans cells and
responsible for activation
of T lymphocytes.
www.indiandentalacademy.com
13. Junction of the epithelium and lamina
propria
The region where C.T. of the lamina propria meets the
overlying Epithelium is an undulating interface at
which papillae of the CT interdigitate with epi. Ridges
This arrangement provide large interface area and
better attachment
www.indiandentalacademy.com
14. Masticatory mucosa has greater number of papillae per
unit area.
In lining mucosa papillae are fewer and shorter
Also represent a major interface for metabolic exchange as
there are no blood vessels in epithelium
www.indiandentalacademy.com
16. Gingival sulcus
It is a crevice or invagination made by gingiva as it joins with
tooth surface .
Gingiva at its margin remains free i.e. doesn’t join the tooth
called Free gingival margin.
Sulcus extends from free gingival margin to dentogingival
junction (junction between tooth surface and gingival tissues)
www.indiandentalacademy.com
17. Sulcus leaves the gingival margin without firm support,
forming a groove called Free gingival groove.
Sulcular (crevicular )epithelium is non keratinized
in humans.
It lacks epithelial ridges and
forms smooth interface with
lamina propria.
It is thinner than the
epithelium of gingiva .
www.indiandentalacademy.com
18. Depth of healthy gingival sulcus varies from
0.5 to 3mm with an average of 1.8 mm
Sulcus is filled with crevicular fluid (GCF) which
passes into oral cavity and mixes with saliva.
GCF contains immunological components and cells
of blood eg. WBCs ,PMNLs, IgG, IgM,& IgA
www.indiandentalacademy.com
19. JUNCTIONS IN ORAL MUCOUS
MEMBRANE
1. Mucocutaneous junction
2. Mucogingival junction
3. Dentogingival junction
DENTOGINGIVAL JUNCTION
The junction between gingiva & tooth -
DENTOGINGIVAL JUNCTION.
The epithelium of gingiva which gets attached to the tooth –
Junctional /Attachment epithelium
The union between this epithelium & tooth -
- Epithelial Attachment
www.indiandentalacademy.com
20. It resembles RER in structure ( a basal layer & few
layers of flattened cells)
It is nondifferentiating ,nonkeratinizing tissue.
It extends upto 2 mm on the surface of the tooth
Has highest turnover rate of 5-6 days ,so
regenerates readily.
Highly permeable
It is a point of least resistance to mechanical forces
and bacterial attack.
www.indiandentalacademy.com
21. Firmness of this junction is maintained by gingival
division of periodontal ligament.
Deeper extention of sulcular epithelium is
junctional (attachment )epithelium ,which lines
floor of gingival sulcus and is attached to tooth
surface by way of epithelial attachment.
www.indiandentalacademy.com
22. Development of junctional (attachment)
epithelium
When the ameloblasts finish formation of the enamel
matrix, they leave a thin membrane on the surface of the
enamel, the primary enamel cuticle.
This cuticle is connected with the interprismatic enamel
substance and the ameloblasts.
www.indiandentalacademy.com
23. The ameloblasts shorten after the primary enamel cuticle
has been formed, and the epithelial enamel organ is
reduced to a few layers of flat cuboidal cells, which are
then called Reduced Enamel Epithelium(RER).
Under normal conditions
RER covers the entire
enamel surface, extending to
the cementoenamel
junction, and remains
attached to the primary
enamel cuticle.
www.indiandentalacademy.com
24. During eruption, the tip of the
tooth approaches the oral
mucosa, and the reduced
enamel epithelium and the oral
epithelium meet and fuse.
The remnant of the primary
enamel cuticle after eruption is
referred to as Nasmyth's
membrane.
The epithelium that covers the
tip of the crown degenerates in
its center, and the crown
emerges through this
perforation into the oral cavity.www.indiandentalacademy.com
25. The reduced enamel
epithelium, remains
organically attached to the part
of the enamel that has not yet
erupted.
Once the tip of the crown has
emerged, the reduced enamel
epithelium is termed the
primary attachment
epithelium.
www.indiandentalacademy.com
26. At the margin of the
gingiva the attachment
epithelium is continuous
with the oral epithelium.
As tooth erupts, the
reduced enamel
epithelium grows
gradually shorter
www.indiandentalacademy.com
27. Summary-
Student should understand-
Keratinocytes and non-keratinocyte cells,
Junctions of oral mucous membranes,
Gingival sulcus and dentogingival junctions.
