AI Technical Summary

Technical Problem

Conventional toothbrushes face challenges in improving plaque removal performance while addressing hygiene concerns in the irregularities formed on the side surface of the bristles.

Method used

A toothbrush with fine irregularity structures on the tip and side surface of the bristles, combined with a nano-diamond particle coating, enhances cleaning efficacy and maintains hygiene by reducing bacterial adhesion.

Benefits of technology

The toothbrush improves plaque removal and maintains hygiene by allowing the irregularities to contact the tooth surface elastically, with the nano-diamond coating preventing bacterial residue.

Description

Technical Field

[0001] The present invention relates to a toothbrush, and particularly to a toothbrush with an improved structure of toothbrush bristles. It relates to a toothbrush.

Background Art

[0002] In conventional toothbrushes, for the purpose of improving the plaque removal performance, the tip shape of the toothbrush bristles is made tapered, round, or stepped, and various structures have been proposed. On the other hand, regarding the structure in which irregularities are formed on the side surface of the toothbrush bristles, although it may contribute to tooth surface cleaning, there is a concern that bacteria and dirt may remain in the irregularities, so it has not been actively adopted.
