Brief summary
This study is a multicentric randomised (2 groups, ratio 1:1) Post Market Clinical Follow-up trial. 38 subjects (teeth) requiring a simple tooth extraction or multiple tooth extraction on the same quadrant and taking curative or preventive antithrombotic treatment will be included (19 in each group). The aim of the study is to assess the efficacy of ETIK COLLAGENE (Topical hemostatic collagen-product) on the hemostasis (time to stop bleeding) after tooth extraction. The hemostasis is measured by assessing the presence of bleeding within the first 8 minutes post-extraction. Group 1: intra-alveolar placement of ETIK COLLAGENE immediately after tooth extraction. Group 2: the alveolus is left empty after tooth extraction (the use of ETIK COLLAGENE is delayed 8 minutes after tooth extraction, before suture). Subjects will be followed-up to 7 days.
Interventions
DEVICEHemostatic dressing ETIK COLLAGENE
The hemostatic dressing ETIK COLLAGENE is placed in the alveolus immediately after tooth extraction. The presence of bleeding in the alveolus is assessed every 30 seconds for 8 minutes; then the surgical site is sutured.
OTHERComparator
The alveolus is left empty after tooth extraction. The presence of bleeding in the alveolus is assessed every 30 seconds for 8 minutes; then the dressing ETIK COLLAGENE is placed in the alveolus and the surgical site is sutured.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Assessment of time to hemostasis after tooth extraction | over 8 minutes after tooth extraction | For each patient, the time to stop bleeding (expressed in minutes) is assessed as follows : every 30 seconds from the tooth extraction (T0) to 8 minutes post extraction, the oral surgeon observes the alveolus during 5 seconds and records the presence or absence of bleeding. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Rate of bleeding at 20 minutes | 20 minutes after tooth extraction | % patients with bleeding occurring after suture, during the 10-minutes local compression period. |
| Occurrence of secondary post-extraction bleeding | 7 days | Number of post-extraction bleeding |
| Level of pain after dental extraction by a numeric scale | At the end of the oral surgery, day 1, day 2, day 3 | The pain is assessed by patients in a diary using a numeric scale (range from 0 (= no pain) to 10 (= the worst pain)) each day from the end of the oral surgery to Day 3. |
| Number of adverse and serious adverse events | From the end of the oral surgery to Day 7 | Adverse events recorded from the tooth extraction to the end of follow-up visit will be used to assess the safety of hemostatic dressing and surgical procedures. |
