- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: PREVENTION
- Time Perspective: None
- Masking: DOUBLE
- Phase: PHASE4
- Number of Arms: 4.0

Eligibility Criteria:
Inclusion Criteria:~* with need for dental extraction~Exclusion Criteria:~* patients under 18 years of age~* antibiotic treatment in the previous three months~* routine use of oral antiseptics~* any type of congenital or acquired immunodeficiency or other disease that could favour the onset of infection or haemorrhagic complications

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: t

Study Arms:
- Control (Type: OTHER): * Blood extraction using the intravenous access 18-22 gauge angiocath catheter (Becton Dickinson, Sparks, MD, USA) (at baseline, 30 seconds and 15 minutes after tooth extraction).~* No prophylactic Chlorhexidine regimen.~* Local anesthesia with lidocaine plus adrenaline (1:100,000).~* Tooth extraction.
- CHX-Mouthwash (Type: ACTIVE_COMPARATOR): * Blood extraction using the intravenous access 18-22 gauge angiocath catheter (Becton Dickinson, Sparks, MD, USA)(at baseline, 30 seconds and 15 minutes after tooth extraction).~* Mouthwash with 0.2% Chlorhexidine (10 ml for 1 minute) (Oraldine Perio®, Johnson and Johnson, Barcelona, Spain).~* Local anesthesia with lidocaine plus adrenaline (1:100,000).~* Tooth extraction.
- CHX-MW/SUB_IR (Type: ACTIVE_COMPARATOR): * Blood extraction using the intravenous access 18-22 gauge angiocath catheter (Becton Dickinson, Sparks, MD, USA) (at baseline, 30 seconds and 15 minutes after tooth extraction).~* Mouthwash with 0.2% Chlorhexidine (10 ml for 1 minute) (Oraldine Perio®) and subgingival irrigation with 1% Chlorhexidine on the tooth to be extracted; the irrigation will be done with the Heraeus Citojet Intraligamental Syringe (Kulzer Heraeus S.A., Madrid, Spain) at six points on each tooth (3 points on the vestibular surface and 3 on the palatine surface).~* Local anesthesia with lidocaine plus adrenaline (1:100,000).~* Tooth extraction.
- CHX-MW/SUPRA_IR (Type: ACTIVE_COMPARATOR): * Blood extraction using the intravenous access 18-22 gauge angiocath catheter (Becton Dickinson, Sparks, MD, USA)(at baseline, 30 seconds and 15 minutes after tooth extraction).~* Mouthwash with 0.2% Chlorhexidine (10 ml for 1 minute) (Oraldine Perio®) and then supragingival irrigation with 1% Chlorhexidine on the tooth to be extracted; the irrigation will be done continuously around the tooth to be extracted by a conventional syringe.~* Local anesthesia with lidocaine plus adrenaline (1:100,000).~* Tooth extraction.
