About this study
Tooth extraction is a common dental procedure, where hemostasis is crucial for patient recovery. This study evaluates the effectiveness of hemostatic sponges in controlling bleeding and promoting postoperative healing.
Read the detailed description
A non-randomized experimental study was conducted at the Santo Tomás de Aquino School of Dentistry Clinic with 30 patients undergoing tooth extractions. They were divided into two groups: one with hemostatic sponges (experimental) and the other without (control). Variables such as bleeding time, wound depth, pain, and postoperative complications at 1, 8, and 15 days were analyzed.
- Conditions
- Hemostasis, Wound Closure, Pain, Extraction Socket Healing

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Hemostatic sponge post tooth extractionProcedure or surgery
Effectiveness of hemostatic sponges in patients undergoing tooth extractions, analyzing immediate hemostasis and scar development at different postoperative times.
| Study group | Role | What they receive |
|---|---|---|
| Hemostatic sponge | Experimental | The colocation of a hemostatic sponge post extraction in the wound Receives: Procedure: Hemostatic sponge post tooth extraction |
| No intervention | No intervention | No colocation of hemostatic sponge in the wound |
What is being measured
The primary outcome is the main question the study is designed to answer.
Post-tooth extraction hemostasis.
Time measured in minutes from the end of the extraction procedure until complete bleeding cessation, assessed by direct clinical observation.
Measured: From the beggining of the treatment inmediatly, then at day 1, day 8, and at day 15
Wound dimensional changes
Measurement of socket length, width, and depth using calibrated periodontal probe. Data will be reported as mean change in millimeters from baseline measurement.
Measured: From the beggining of the treatment inmediatly, then at day 1, day 8, and at day 15
Pain intensity
Pain intensity measured using Visual Analog Scale (VAS). Higher scores indicate worse outcome.
Measured: From the beggining of the treatment inmediatly, then at day 1, day 8, and at day 15
Edema assessment
Edema assessed by clinical examination using a 4-point scale: 0 = no edema, 1 = mild edema, 2 = moderate edema, 3 = severe edema. Higher scores indicate worse outcome.
Measured: From the beggining of the treatment inmediatly, then at day 1, day 8, and at day 15
Tissue color changes evaluation
Evaluation of tissue color changes using a standardized 5-point wound healing color scale: 1 = normal pink, 2 = pale pink, 3 = red, 4 = dark red/purple, 5 = black/necrotic. Higher scores indicate worse healing.
Measured: From the beggining of the treatment inmediatly, then at day 1, day 8, and at day 15
Post-extraction complications
Incidence of post-extraction complications including but not limited to: dry socket, infection, delayed healing, excessive bleeding, and nerve damage. Complications will be assessed by clinical examination and participant reporting.
Measured: From the beggining of the treatment inmediatly, then at day 1, day 8, and at day 15
