2. WHAT IS ABSCESS? CLINICAL DIAGNOSIS STAGES
There are Four stages in progression of acute odontogenic
infections:
Stage 1: Odontogenic in origin. periapical or periodontal or peri-coronal
infection. Patient may be asymptomatic.
Stage 2: Still confined with in the alveolar bone. it is termed as periapical
osteitis. Tooth is tender to percussion and frequently extruded from the
socket. Patient complains of severe pain.
Stage 3
Once the infection exits through the bone and the periosteum into the surrounding
soft tissue ,an inflammatory oedema occurs A diffuse swelling develops extra-orally
which is soft and duffy in consistency called Cellulitis. At this stage no pus
formation occurs.
Stage 4 : When suppuration does occur and the infection
localises, the condition is termed as, Abscess. With increased
pressure it may even perforate the soft tissues and pus discharge may be
seen as sinus opening or fistulous tract.

7. Vestibular/Buccal Abscesses
Etiology:
The buccal space abscess may originate from
infected root canals of posterior teeth of the
maxilla and/or mandible.
Boundaries-
Superiorly: zygomatic arch.
Inferior: inferior border of mandible.
Laterally: skin & subcutaneous tissue.
Medially: buccinator muscle ,buccopharyngeal
fascia.
Posteriorly: anterior edge of masseter muscle.
Anteriorly: posterior border of zygomaticus
major & depressor
anguli oris.
Contents-
Buccal fat pad.
Stenson’s duct.
Facial artery.
8. CLINICAL EVALUATION:
• It is characterized by swelling of the
cheek, which extends from the
zygomatic arch to the inferior
border of the mandible,
• from the anterior border of the
ramus to the corner of the mouth.
• The skin appears taut and red, with or
without fluctuation of the abscess,
which, if neglected, may result in
spontaneous drainage.
• Dumb bell shaped appearance due to
lack of swelling over zygomatic arch.
Buccal Abscesses
9. • swelling of the cheek
• extends from the zygomatic arch to the inferior border of the mandible
• from the anterior border of the ramus to the corner of the mouth
• skin appears taut and red, with or without fluctuation of the abscess
Differential Diagnosis:
Repeated buccal space infection suspect Crohn’s Disease.
10. Access to the buccal space is usually intraoral for three main reasons:
The abscess fluctuates intraorally in the majority of cases
To avoid injuring the facial nerve
For esthetic reasons
The intraoral incision is made at the posterior region of the mouth, in an
anteroposterior direction, and carefully to avoid injury of the parotid duct.
A hemostat is then used to explore the space thoroughly.
An extraoral incision is made when intraoral access would not ensure adequate
drainage, or when the pus is deep inside the space.
The incision is made approximately 2 cm below and parallel to the inferior border of
the mandible.
Broad spectrum gram positive + gram negative antibiotic treatment for 7-14 days.
In case of granular growth, biopsy can be performed.
1. can progress to lymphangitis, more abscess formation, or sepsis.
2. Infection by additional species of bacteria (superinfection) may occur,
complicating treatment. Infection can also spread to the layer of tissue
enveloping muscles (fascia), causing a serious infection (necrotizing fasciitis).
3. Older individuals may develop a blood clot (thrombophlebitis) as a result of
cellulitis in more superficial tissues.

COMPLICATIONS
11. Canine Fossa Abscess
Anatomic Location: The canine fossa, is a
small space between the levator labii
superioris and the levator anguli oris muscles.
Etiology: Infected root canals of canines of
the maxilla or premolars are considered to be
responsible for the development of abscesses
of the canine fossa.
Clinical Presentation: This is characterized
by edema, localized in the infraorbital region,
which spreads towards the medial canthus of
the eye, lower eyelid, and side of the nose as
far as the corner of the mouth.
There is also obliteration of the nasolabial
fold, and somewhat of the mucolabial fold.
The edema at the infraorbital region is painful
during palpation, and later on the skin
becomes taut and shiny due to suppuration,
while its color is reddish.

swelling after an episode of trauma 3 weeks
previously. He feels unwell and his right eye is
closing. Example of Canine Fossa abscess
The edema at the infraorbital region is painful
during palpation, and later on the skin becomes
taut and shiny due to suppuration, while its colour
is reddish.
13. Treatment of Canine Fossa Abscess
The incision for drainage is performed intraorally at the
mucobuccal fold (parallel to the alveolar bone), in the canine
region.
A hemostat is then inserted, which is placed at the depth of the purulent
accumulation until it comes into contact with bone. Finally, a rubber drain
is placed, which is stabilized with a suture on the mucosa.

• Oral cancer diagnosis
• Sublingual and submandibular gland infection
• Lingual nerve
27. • The incision for drainage is performed
on the skin, approximately 1 cm beneath

mandible.
• During the incision, the course of the
facial artery and vein (the incision
should be made posterior to these) and
the respective branch of the facial
nerve should be taken into
consideration.
• A hemostat is inserted into the cavity of
the abscess to explore the space and an
attempt is made to communicate with the
infected spaces.
