Study summary

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.

What researchers measure

Primary outcomes

  1. Post-tooth extraction hemostasis.

    Time measured in minutes from the end of the extraction procedure until complete bleeding cessation, assessed by direct clinical observation.

    Time frame: From the beggining of the treatment inmediatly, then at day 1, day 8, and at day 15

  2. 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.

    Time frame: From the beggining of the treatment inmediatly, then at day 1, day 8, and at day 15

  3. Pain intensity

    Pain intensity measured using Visual Analog Scale (VAS). Higher scores indicate worse outcome.

    Time frame: From the beggining of the treatment inmediatly, then at day 1, day 8, and at day 15

  4. 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.

    Time frame: From the beggining of the treatment inmediatly, then at day 1, day 8, and at day 15

  5. 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.

    Time frame: From the beggining of the treatment inmediatly, then at day 1, day 8, and at day 15

  6. 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.

    Time frame: From the beggining of the treatment inmediatly, then at day 1, day 8, and at day 15

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Aug 2024 to primary completion in Mar 2025, 7 months.

Of 3,731 non-industry interventional studies with no phase under Pain, half reached primary completion within 10 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 23. This study's 7 months is below that.

Counting every sponsor, half of 3,830 studies reached it within 10 months; a quarter within 4 and three quarters within 23.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 14, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
