UST brushware uses a unique construction method that eliminates the need for staples or resin to hold the bristles in place. Every bristle is individually fixed during the molding process, ensuring consistent and strong fixation throughout the brush. This design significantly reduces bristle loss and minimizes the risk of foreign body contamination.

Bristle thickness still plays a role in determining when a bristle breaks. Thinner bristles require less force to break, regardless of the brush type.

Determination of Average Bristle Fixation Strength

We measured the average force needed to pull bristles from a UST brush and a standard D&S brush. Based on 60 pulls per brush, the average fixation strength for the UST brush was 5.34 N, compared to 3.53 N for the standard D&S brush.

This means it takes about 52% more force to dislodge a UST bristle than a standard one.

Calculating the percentage difference:

• 5.34 - 3.53 = 1.81
• 1.81 / 3.53 * 100 = 51.5%

So, on average, it takes 52% more force to remove a UST bristle than a standard one.

Determination of Bristle Fixation Variability

We also analyzed the variability in fixation strength using Standard Deviation. For the UST brush, the average was 5.34 N with a Standard Deviation of 0.57 N. For the D&S brush, the average was 3.53 N with a Standard Deviation of 1.18 N.

Using these values, we calculated the Percentage Variance:

• For UST: (100 / 5.34) * 0.57 = 10.67%
• For D&S: (100 / 3.53) * 1.18 = 33.43%

This shows that UST provides over three times better consistency in bristle fixation compared to standard brushes.

Summary

• It takes 52% more force to remove a UST bristle than a standard one.
• UST provides over three times better consistency in bristle fixation.
