ORAL SURGERY
Extractions
BACKGROUND
When an extraction is required, patients expect that it will be
accomplished painlessly and skillfully. Unfortunately, not all ex-
tractions are simple and some can be extremely challenging for
dentists. The current issues related to exodontia, including its
diagnosis, indications, technique, complications, and manage-
ment, were explored.
DIAGNOSIS AND INDICATIONS
Diagnostic Process
When exodontia is being considered, a thorough diagnostic process
must be undertaken to ensure that it's the correct course of action
(Table 1). This includes a complete history, clinical examination, and
diagnostic tests as indicated. In addition, pre-extraction radiographs
can verify the diagnosis and reveal any potential difficulties in store
for the dentist (Figure 1).Both pulp sensitivity and periodontium sta-
tus can also add invaluable information.
