Objective:

To demonstrate the existence of bacterial aggregation to the suture materials that are usually used in dental practice, to verify if aggregation is related to the inflammation that occurs after the surgical act and finally give recommendations on what type of suture is best suited for the prevention of bacterial adhesion.

Material and method:

Bibliographic search through PubMed, Cochrane and Scielo databases using the keywords: surgical sutures, bacterial adherence. Inclusion criteria were accepted studies published in the last 15 years, in vivo or in vitro in relation to oral surgery and with a level of scientific evidence of more than 3 according to the criteria of scientific evidence. All those publications that did not have the suture subject Silk, Nylon™, Supramid™, Monocryl™, Vicryl™ or Vicryl Plus™ were excluded. All publications that did not relate suture materials to bacterial aggregation were also excluded.

Results:

A total of 9 publications were organized according to the type of suture used, whether they were in vivo or in vitro studies, the number of patients/samples, time elapsed until removal of the sutures, controls if they were performed, any type of inflammatory reaction, which type of bacteria were added and which material obtained greater aggregation.

Discussion:

The suture materials with the greatest accumulation of bacterial plaque present under the same conditions of exposure to bacteria, are the reabsorbable multifilament type not treated with antimicrobials.
