This document summarizes potential complications that can arise from tooth extractions. It discusses soft tissue injuries, problems that can occur with extracting a tooth like root fractures, injuries to adjacent teeth, osseous structures, and other adjacent structures. It also outlines complications like oroantral communications, postoperative bleeding, delayed healing, infections, and mandible fractures. The document references two studies conducted on dry socket prevalence and risk factors at dental centers in Palestine and Jordan.
Presentation by Weam Faroun and Rasha Hamdallah for Dr. Kareem Abu Libdeh; outlining topics like soft tissue injuries, tooth extraction problems, and complications.
Discusses types of soft tissue injuries: mucosal flap tears, puncture wounds, and abrasions, which can occur during surgery.
Outlines issues during tooth extraction, including root fractures, displacements, and cases where a tooth may be lost into the pharynx.
Details risks to nearby teeth during procedures, including restoration dislodgment, tooth luxation, and the extraction of the wrong tooth.
Examines bony injuries during extraction, specifically fractures of the alveolar process and maxillary tuberosity.
Describes potential injuries to regional nerves and the temporomandibular joint during dental procedures.
Addresses oroantral communications post-extraction and emphasizes the importance of preventing postoperative bleeding.
Highlights factors causing delayed healing post-extraction, including infections, wound dehiscence, and dry sockets.
Presents study data on tooth extractions, dry socket incidences among smokers/non-smokers, single/multiple extractions, and age effects.
Describes the rare occurrence of mandible fractures during tooth extraction, primarily related to extracting impacted third molars.
Lists references including literature on dry socket frequencies and clinical studies for further exploration of oral surgical risks.

POSTOPERATIVE BLEEDING
DELAYED HEALING AND INFECTION
FRACTURES OF THE MANDIBLE
TEAR OF AMUCOSAL FLAP
The most common soft tissue injury , as the
surgeon tries to gain needed surgical access .
5.
PUNCTURE WOUND
Thisinjury is the result of using uncontrolled force .
Instruments such as a straight elevator or a periosteal
elevator may slip from the surgical field and puncture or tear
into adjacent soft tissue.
6.
STRETCH OR ABRASION
Abrasions or burns to lips, corners of the mouth, or flaps
usually result from the rotating shank of the bur rubbing on
soft tissue or from a metal retractor coming in contact with soft
tissue .
7.
PROBLEMS WITH ATOOTH BEING
EXTRACTED
Root Fracture Root
Displacement
Tooth Lost into
the Pharynx
8.
ROOT FRACTURE
Long,curved, divergent roots that lie in dense bone are the
most likely to be fractured .
EXTRACTION OF THEWRONG TOOTH
A common reason for removing the wrong tooth is that a
dentist removes a tooth for another dentist.
If the wrong tooth is extracted and the surgeon realizes this
error immediately, the tooth should be replaced quickly into
the tooth socket .
When the wrong tooth is extracted, it is important to inform the
patient, the patient’s parents or caregivers (if the patient is a
minor), and any other dentist involved with the patient’s care .
FRACTURE OF THEALVEOLAR
PROCESS
The most likely cause of fracture of the alveolar
process is the use of excessive force with the
forceps, which fractures the cortical plate .
17.
FRACTURE OF THEMAXILLARY
TUBEROSITY
The maxillary tuberosity is important for the
construction of a stable retentive maxillary denture.
1)INJURY TO REGIONALNERVES.
The nasopalatine and buccal nerves are frequently
sectioned during the creation of flaps for removal of
impacted teeth.
Surgical removal of mandibular premolar roots or
impacted mandibular premolars or periapical surgery
in the area of the mental nerve and mental foramen
must be performed with great care.
21.
flap three-cornerflap is to be used in the area of the
mental nerve, the vertical-releasing incision must
be placed far enough anteriorly to avoid severing
any portion of the mental nerve.
22.
Incisions madein the retromolar pad region of the
mandible should be placed so as to avoid coming
close to lingual nerve complication
23.
inferior alveolarnerve may be traumatized along
the course of its intrabony canal. The most common
place of injury is the area of the mandibular third
molar
Prevention ofPostoperative Bleeding
1. Obtain a history of bleeding.
2. Use the atraumatic surgical technique.
3. Obtain good hemostasis at surgery.
4. Provide excellent patient instructions
INFECTION
The mostcommon cause of delayed wound healing
is infection. Infections are a rare complication after
routine dental extraction and are primarily seen
after oral surgery that involves the reflection of soft
tissue flaps and bone removal.
34.
2)WOUND DEHISCENCE
Ifa soft tissue flap is replaced and sutured without
an adequate bony foundation, the unsupported soft
tissue flap often sags and separates along the line
of incision. A second cause of dehiscence is
suturing the wound under tension.
35.
DRY SOCKET
Drysocket or alveolar osteitis is delayed healing
but is not associated with an infection. This
postoperative complication causes moderate to
severe pain but is without the usual signs and
symptoms of infection such as fever, swelling, and
erythema.

DENTAL TEACHING CLINICSOF
AL QUDS UNIVERSITY STUDY
During this study, 1305 permanent tooth extractions
were performed in 805 patients.
58% male patients and 42% female patients.
Data were collected over a period of 16 months, from
October 1st 2006 to January 28th 2008.
37.
dry socketincidence: non-surgical extraction of teeth was 1.7 %
surgical extraction was 12%
Dry socket: in(18-33) year is 4.8 %
in (34-49) year is 2.9%
In more than 50 year is 1.6%
42.
Study of thePrevalence, clinical picture, and risk
factors of dry socket in a Jordanian dental
teaching center.
CONCLUSION of the study:
Smoking and surgical trauma are associated with an
increased incidence of dry socket. Moreover,
patients who had single extractions were more
likely to develop dry socket than those who had
multiple extractions in the same visit.
43.
Fracture ofthe mandible during extraction is a rare
complication; it is associated almost exclusively
with the surgical removal of impacted third molars.
