Summary
Nylon sutures demonstrated lower bacterial accumulation compared to silk, polyglactin, and polyester sutures after oral surgery. Suture material significantly impacts microbial load, while surgery type and antibiotics have minimal effect.
Area of Science:
- Oral surgery
- Microbiology
- Biomaterials
Background:
- Bacterial accumulation on sutures can lead to surgical site infections.
- Understanding suture material's role in bacterial adhesion is crucial for patient outcomes.
Purpose of the Study:
- To compare bacterial accumulation on four common suture materials after oral surgery.
- To investigate the influence of surgery type, periodontal diagnosis, and antibiotic use on suture bacterial load.
Main Methods:
- Four suture types (silk, coated polyglactin, nylon, polyester) were placed in patients undergoing implant or periodontal surgery.
- Sutures were removed after 10 days, incubated for 7 days, and colony-forming units (CFUs) were quantified.
- Statistical analysis assessed associations between bacterial accumulation and clinical factors.
Main Results:
- All tested sutures harbored bacteria.
- Nylon sutures exhibited significantly lower CFUs than silk, polyglactin, and polyester sutures.
- Surgery type, periodontal diagnosis, and antibiotic treatment showed minimal impact on bacterial accumulation.
Conclusions:
- Monofilamentous nylon sutures show reduced microbial accumulation compared to braided materials.
- Suture material properties and macrostructure influence bacterial adhesion.
- Clinical factors like surgery type and antibiotics have limited effect on suture bacterial load.

Heat is a widely used method to control microbial growth by targeting and denaturing cellular proteins, thereby killing or inactivating microbes. This method's effectiveness is quantified using parameters such as the thermal death point (TDP), thermal death time (TDT), and decimal reduction time (D value). TDP represents the lowest temperature at which all microorganisms in a liquid suspension are eliminated within 10 minutes, whereas TDT is the time necessary to achieve sterilization at a...
