Summary
Older age increases complication risks after third molar (M3) surgery. Patients over 25 undergoing M3 extraction face a higher likelihood of complications, highlighting age as a key risk factor.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Public Health
- Surgical Outcomes Research
Background:
- Third molar (M3) extraction is a common surgical procedure.
- Understanding complication rates and associated risk factors is crucial for patient safety.
- Age has been anecdotally suggested as a risk factor for M3 surgery complications.
Purpose of the Study:
- To estimate the frequency of complications following third molar (M3) surgery.
- To investigate the association between patient age and the risk of M3 extraction complications.
Main Methods:
- Prospective cohort study involving 4,004 subjects undergoing 8,748 M3 extractions.
- Data collected on demographic, health status, anatomic, and pathological variables.
- Univariate, bivariate, and multiple logistic regression analyses were performed to identify risk factors.
Main Results:
- The overall complication rate was 19% in the study sample.
- Bivariate analyses indicated multiple factors associated with complications, including age >25 years.
- Multiple logistic regression confirmed that age above 25 years was significantly associated with an increased risk of complications (OR=1.5, P=.05).
Conclusions:
- Increased age (>25 years) is associated with a higher complication rate after third molar extractions.
- Age should be considered a significant risk factor in M3 surgery planning and patient counseling.
- Further research may explore specific age-related biological mechanisms influencing surgical outcomes.

01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

01:26Factors Affecting the Risk of Infection
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 create...
