Only 4% cases have periapical infection
in the extracting tooth/ teeth.
It is also stated that a DC can be caused by inflammation of the periapical tissues due to necrosis or a periapical infection
originating from the primary predecessor tooth, which could stimulate the developing tooth germ follicle (9).
The tooth itself ideally should be non carious or in the very least not have any pulpal involvement or periapical infection
Persistent periapical infection
despite surgical procedures can be eliminated with careful endodontic intervention.
The periapical infection
of tooth 12 (suppurative chronic apical periodontitis) improved as a consequence of the endodontic treatment; the fistulous tract disappeared as well as the remaining signs and symptoms of the lesion.
Mucous contusion or abrasion, sinusitis, tooth extraction, oral and maxillofacial surgery, maxillofacial trauma, dental pulp exposure and endodontic treatment, periapical infection
or granuloma, periodontal disease, local anesthesia, tooth eruption, poor hygiene and tonsillectomy are important risk factors of cervicofacial actinomycosis (2).
Most common cause of odontogenic infections was periapical infection
due to necrotic dental pulp in 83%, followed by pericoronitis in 13.
As a consequence of the periapical infection
, the prognosis of tooth 13 was considered to be poor even though the resorptive process had apparently ceased.
All teeth had periapical infection
, mobility and perical radiolucency.
19 Lack of use of rubber dam in 87% of the cases was recorded as the major factor for failure followed by periapical infection
Previous studies showed that for acute periapical infection
around 60% of the surveyed dental surgeons prescribed antibiotics before drainage and after drainage.
