Summary
Delayed-onset infection after lower third molar surgery is linked to younger age and specific impaction characteristics. Careful follow-up and oral hygiene are crucial for at-risk patients to prevent complications.
Area of Science:
- Oral and Maxillofacial Surgery
- Infectious Disease Research
- Dental Public Health
Background:
- Delayed-onset infection, characterized by swelling and pain around 30 days post-surgery, is a potential complication of surgical procedures.
- Understanding predisposing factors for delayed-onset infection is crucial for improving patient outcomes and surgical protocols.
Purpose of the Study:
- To investigate the occurrence of delayed-onset infection following lower third molar surgery.
- To identify potential predisposing factors associated with the development of delayed-onset infection.
Main Methods:
- A retrospective case-control study involving 223 lower third molar surgeries.
- Analysis of 1102 outpatients, comparing cases with delayed-onset infection to a healthy control group.
- Statistical analysis included Shapiro-Wilk, Mann-Whitney U, and Fisher's exact tests.
Main Results:
- Delayed-onset infection complications occurred in patients under 26 years old, approximately 29.5 days post-surgery.
- Significant risk factors included younger age, total soft tissue coverage, deeper impaction, lower Nolla stage, mesioangular direction, and full bone coverage.
- Absence of distal space was inversely correlated with complications.
Conclusions:
- Lower Nolla stage, extensive soft tissue coverage, lack of distal space, deeper impaction, and mesioangular tilt are identified as potential promoters of delayed-onset infection.
- Recommend vigilant follow-up for at-risk patients and emphasize the importance of maintaining oral hygiene to mitigate infection risk.

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
