Considering the wide variety of surgical sutures currently marketed in the field of Dentistry, it was decided to conduct a study comparing the microbial adhesion and antibacterial activity of three different types of sutures used in Oral Surgery (Silk, non-absorbable polyamide monofilament and non-absorbable expanded polytetrafluoroethylene).

The general or primary objective is:

• To compare 3 non-absorbable suture materials used in oral surgery: silk, polyamide monofilament and expanded polytetrafluoroethylene.

The specific or secondary objectives are:

• To evaluate how each type of suture influences wound healing and the patient's postoperative period.
• To study bacterial colonization in each type of suture.
• To determine the tissue reaction and clinical characteristics of each suture.

Inclusion Criteria:

• Patients with indication for extraction of a third lower molar retained in an unfavorable position that requires a bayonet incision in the surgical procedure.
• Age: patients aged 18 years or older.
• ASA I patients (Classification of the American Society of Anesthesiology, 1979): healthy patients who tolerate stress well, without systemic pathology, no anxiety and in whom a therapeutic modification is not necessary.

Exclusion Criteria:

• Pregnant or breastfeeding women.
• Smoking patients.
