The quantified method for blood clot detection in the extraction socket

Area of Science:

• Dental Surgery
• Hemostasis Research
• Biomedical Measurement

Background:

• Current methods for assessing extraction socket hemostasis rely on subjective clinical observation.
• There is a lack of objective, quantified measurements for detecting blood clots during this process.
• This limitation impacts both clinical practice and research involving extraction sockets.

Purpose of the Study:

• To evaluate the in vitro reliability and clinical validity of a novel objective measurement technique for blood clot detection (BCD).
• To introduce a quantified data-providing method using a standard capillary tube for assessing hemostasis.
• To establish a more accurate assessment of blood clot formation in extraction sockets.

Main Methods:

• In vitro reliability testing used blood samples from ten healthy participants in simulated bleeding sockets.
• Clinical-relevant validity involved assessing sixteen extraction sockets per participant.
• Blood-filled distances in capillary tubes were measured and compared with clinical observations over a 30-minute period.

Main Results:

• The blood clot detection (BCD) measurement demonstrated excellent test-retest reliability (ICC = 0.980).
• Significant differences in blood-filled distances were observed between active bleeding (13.0 mm), sluggish oozing (5.6 mm), and clot formation (0.9 mm) groups (p<0.001).
• BCD measurement accurately indicated the completion of hemostasis.

Conclusions:

• A blood-filled distance of 0.9 mm in the capillary tube reliably signifies complete clot formation.
• The BCD measurement offers a quantified and objective tool for assessing extraction socket hemostasis.
• This method enhances the accuracy of hemostasis evaluation in dental procedures.
