Which type of sutures conduct a greater number of bacteria?

Multifilament sutures are made from multiple strands of material twisted together, which creates interstices between the strands. These small spaces can harbor bacteria, allowing for a greater microbial load compared to other suture types. This characteristic increases the risk of infection at the surgical site, as bacteria can easily reside within the fibers.

Monofilament sutures, in contrast, consist of a single strand, making them less prone to collect and retain bacteria due to their smooth surface. Silk sutures, while multifilament, also have a tendency to promote bacterial colonization when compared to monofilament due to their structure and moisture retention. Absorbable sutures might face fewer concerns in this area since they are typically used for temporary support and often degrade in a way that limits prolonged bacterial entrapment.

Thus, the construction of multifilament sutures, which allows for greater surface area and more space for bacteria to thrive, directly contributes to their increased conductivity for bacteria. This is a key consideration in periodontal surgeries where contamination and infection control are crucial for successful healing.
