Dry socket, or alveolar osteitis, is an inflammation of the alveolar bone that can occur following tooth extraction, particularly in mandibular wisdom teeth, affecting 1-30% of cases. Symptoms include severe pain and halitosis, usually arising 2-3 days post-extraction, while treatment involves cleaning the socket and using analgesics. Prevention strategies include maintaining good oral hygiene and avoiding smoking and certain activities post-surgery.

3. DEFINITIO
N:
Dry socket is also called Alveolar
Ostitis.
It refers to the inflammation of the
alveolar bone which commonly occurs
as a complication of tooth extraction.

4. EPIDEMIOLOGY
 A dry socket will occur in only 1% to 3% of
all tooth extraction.
 But its more common in the extraction of
Mandibular Wisdom teeth.
 In lower impacted wisdom teeth, as many
as 25% to 30% of cases will result dry
socket.

5. PATHOPHYSIOLOGY:
 After tooth extraction, a blood clot forms on the
socket of the extracted tooth, mainly to reduce
blood loss due to the extraction and also to
prevent the alveolar bone from getting exposed to
the oral environment.
 When this blood clot fails to form or is physically
lost from the socket, the alveolar bone gets
exposed to the oral saliva, bacteria and food
debris.
 This results in localized inflammation of the
alveolar bone, leading to a severe throbbing pain
that radiates to the jaws, ears and eyes of the
affected side.

6. SIGNS AND
SYMPTOMS:
 Symptoms
 Severe pain.
 Onset : 2 – 3 days after extraction.
 Radiation: Pain radiates to the jaws, ears ,eyes
and neck of the affected tooth.
 Intra-oral Odor (Halitosis)
 Bad taste in the mouth.
 Regional Lymphadenopathy (Rare).

7. SIGNS:
 Empty socket:-That partially or totally lacks
blood clot.
 Exposed bone:- Visible and sensitive to touch
 Inflammation of the soft tissue around.
 Food debris trapped in the socket.

8. AETIOLOGY
:
 Smoking.
 Traumatic extraction.
 Poor oral hygiene.
 Patients with history of dry sockets.
 Surgical extraction of wisdom teeth.
 Oral contraceptives.
 Pre-existing infection: (pericoronitis)

9. TREATMENT:
 Cleaning socket by removing food debris-
use saline irrigation for better cleaning.
 Using medicated dressings e.g Alvogil
 Analgesics for pain relief.
 Antibiotics.

10. PREVENTION:
 No smoking before and after tooth
extraction.
 No spitting, eating, washing or using
straw for drinks .
 Good oral hygiene.
 Do not touch the extraction wound with
your tongue, fingers e.t.c
 Eat cold soft food to avoid irritating the
wound.
