Study information
| Study design | Randomised double blind placebo controlled parallel group trial |
|---|---|
| Primary study design | Interventional |
| Secondary study design | Randomised controlled trial |
| Study setting(s) | Hospital |
| Study type | Treatment |
| Scientific title | |
| Study acronym | BLACK |
| Study objectives | Common traditional practice until now has been discontinuation of the antiplatelet therapy 7 to 10 days prior to dental surgery, but controlled prospective data in the literature to support this practice are lacking. The discontinuation of antiplatelet treatment to ensure an adequate hemostasis during and after dental surgery needs to be offset against the (rebound) risk of thrombo-embolic complications if this treatment is stopped. The hypothesis is that antiplatelet therapy can safely be continued prior to dental surgery. |
| Ethics approval(s) | Received from local medical ethics committee |
| Health condition(s) or problem(s) studied | Parodontitis apicalis, adult parodontitis, caries |
| Intervention | Patients will be randomised to continue their medication of anti-platelet agents during the ten days prior to the procedure or to stop treatment. The study will be double blind; hence, patients will receive their initial medication in the form of study medication or placebo in the form of study medication for ten days prior to their treatment. |
| Intervention type | Other |
| Primary outcome measure | Peri-procedural blood loss |
| Secondary outcome measures | 1. Occurrence of thrombo-embolic events at 30 days follow-up 2. The predictive effect of measurements in DNA, blood and saliva on peri-procedural hemostasis and blood loss |
