I. General Supportive Measures(Helping the body to overcome infection)

Bed rest and hospitalization

Adequate nutrition High caloric and vitamins diet

Excessive fluids to compete dehydration

Restoration of fluid balance

Sedatives and analgesics To relief pain

To allow sleeping

Infection & Fever DehydrationFluid Imbalance

Fluids

By Mouth or

IV Fluids

II. Administration of Antibiotics

Types of antibiotics Bacteriostatic

Inhibit bacterial growth

Bactericidal

Kill bacteria

Action of antibiotics Interfere with cell protein synthesis

Affect cell membrane

Escape of essential metabolites

result in osmotic difference

Bacteria absorb water, swollen

and finally brust

Swollen

Brust

Absorb water

Dose All Cases Need Antibiotics

Simple localized abscess

I&D is enough

No need for antibiotics

Spreading type of infection

Administration of antibiotics will

Help localization

Affect resolution or pus formation

Before Surgery

Antibiotics will guard against infection and

prevent spreading

If PUS is formed antibiotics will

Limits spread of infection

Relief pain and pyrexia

Decrease swelling

But “PUS will never be eliminated”

(Antibiotic Abscess)

III. Heat Therapy

Types Conductive heat (1)

Mouth washes & Gargles

Bags, Bottles & Politics

Convective (2)

Water or Paraffin wax

Conversive heat (3)

Tungsten lamb & Carbon lamb

Remember that heat without antibiotics

has very little or no effect

Effect of Heat

HEAT

Lymphatic Vessels Blood Vessels

Increase Blood Flow

Vasodilatation

Increase Edema Formation Increase Lymphatic Drainage

•Increase phagocytosis

•Increase metabolic rate in the area

• Muscle relaxant effect

• Counter irritant effect

• Sedative effect

• Increase blood tissues exchange

• Increase rate of metabolism

IV. Surgical Treatment (I&D) (Surgical Evacuation of Pus)

What is the OPTIMAL Time for I&D No hard rule to follow

Too EARLY evacuation

Little pus

No harm

Late evacuation

More spread will occur

Spontaneous drainage may occur

When in doubt Do Aspiration

Be familiar with S&S of pus under deep fascia

NEVER

let

SUNSET

on

prisoned

PUS

Signs of PUS under deep fascia

Localized dusky redness in the general redness of the

swelling

Pitting edema

Recurrent pyrexia or sudden raise in temperature

Lack of improvement with adequate treatment

Surgical Evacuation of Pus(Incision & Drainage – I&D)

Incision should be placed Over area of maximum fluctuation

In an area that affect maximum drainage

Over the most direct route to pus

Skin incision Should be placed in one of the lines of skin creases (tension lines of the

skin) or parallel to it

Mucoperiosteal incision Should be paced parallel to the alveolar bone in the palate and in the

floor of the mouth

Should avoid injury to the mental nerve in the lower premolar region

The Drain

Function of the drain Keep the incision opened

Allow the escape of pus or inflammatory exudates from the lesion

After surgery

Remove serum, exudates and foreign materials

Prevent hematoma or seroma formation

Decrease the chance of postoperative infection

Types of drains Intra-oral drains

Gauze strips drain

Rubber dam strips drain

Extra-Oral drains

Gauze and rubber dame strips

Penrose drain

Rubber catheter

Insertion of the drain Applied loosely

Reach the deepest part of the abscess

Part of the rain should project from the incision

Changed every 24-48 hours

Remove when there is no drainage (non-productive)

V. Treatment of the Cause

The causative tooth is either RCT or extracted

Vestibular abscess on the maxillary alveolar process

A 31-year-old man with increasing dental pain in the left maxilla. Pain initially was

heat dependant but becomes continuous the previous night. This was accompanied

by swelling in the left cheek. X-ray was negative at this stage

Page 17: Treatment of Oral & Maxillofacial Infectiondoccdn.simplesite.com › d › a7 › f2 › 282882356072084135 › e0d46a... · 2016-10-13 · After surgery Remove serum, exudates and

17

Infiltration anaesthesia is given within the mucosa only.

Infiltration injection is given near the tuberosity beyond

the extent of the abscess

Page 18: Treatment of Oral & Maxillofacial Infectiondoccdn.simplesite.com › d › a7 › f2 › 282882356072084135 › e0d46a... · 2016-10-13 · After surgery Remove serum, exudates and

The blade is guided horizontally, perpendicular to the osseous surface

approximately at the muco-gingival border. Diagram shows the correct orientation

for the primary incision

The entrance into the abscess cavity is widened using a periosteal elevator or a blunt

hemostat, and the pus is pressed out.

Rinsing the abscess cavity with normal saline or antibiotic solution may be useful

20

Drainage of the abscess is ensured by

placing a gauze strip drain

The drain is changed daily

Treatment of the offending tooth should be

started before the end of treatment of the

abscess

Treatment of the abscess was completed 14 days postoperatively

The radiograph shows successful root canal treatment of the offending tooth

Mandibular Buccal Sub-periosteal Abscess

22-year-old girl suffering from pain in the lower right premolar region for several weeks. The

pain subsided and swelling began to occur three days later on the right side of the mandible.

X-ray shows an area of bone resorption related to a remaining root of lower right first

premolar surrounded by a partial zone of reactive sclerosis

Page 23: Treatment of Oral & Maxillofacial Infectiondoccdn.simplesite.com › d › a7 › f2 › 282882356072084135 › e0d46a... · 2016-10-13 · After surgery Remove serum, exudates and

Anaesthesia: In

addition to nerve block

anaesthesia topical

anaesthesia is applied

to mucosa. This help to

decrease pain with the

incision

Incision: Scalpel cut through both the mucosa and the periostium

as it is guided perpendicular to the bone surface

The diagram demonstrate the correct orientation of the scalpel

Page 24: Treatment of Oral & Maxillofacial Infectiondoccdn.simplesite.com › d › a7 › f2 › 282882356072084135 › e0d46a... · 2016-10-13 · After surgery Remove serum, exudates and

24

The periosteal elevator is used to widen the opening to the abscess cavity, allowing

adequate drainage of pus

Extraction of the offending root is performed after incision and drainage of the

abscess. This is to prevent pus from spreading submucosally when pressure is

applied to the alveolar process as the tooth is extracted

Page 25: Treatment of Oral & Maxillofacial Infectiondoccdn.simplesite.com › d › a7 › f2 › 282882356072084135 › e0d46a... · 2016-10-13 · After surgery Remove serum, exudates and

25

The abscess cavity is

rinsed using warm

normal saline

Drainage: Strip of gauze is placed in the abscess cavity. The

drain can be saturated with disinfectant solution

Follow-up: First follow-up appointment should be 24 hours

after surgery, the drain is removed, abscess cavity is rinsed

and a new drain is reinserted

Canine fossa (infraorbital) abscess:

Palpation in the right upper buccal vestibule revealed a discrete well demarcated and

indurated swelling

X-ray shows a non-vital upper right second premolar

Anaesthesia: Extraoral infaorbital nerve block is essential to avoid intraoral injection

which has to pass the needle through the abscess

Intraoral infiltration injection distal to the inflamed area

Incision: The incision is made in a horizontal

direction with the scalpel blade perpendicular to

the bone surface

A periosteal elevator is used to widen the opening
