Injection molded endodontic brush

Abstract

Unitary, one-piece plastic molded micro-brushes are provided to remove the smear layer that remains in the root canal and access chamber after the pulp, bacteria, and related irritants have been mechanically and chemically removed from the root canal and access chamber using rotary cutting burs, files and various chemical reagents. The brushes include a handle, shaft or shank and a tapered brush section extending from the distal end of the shank.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Application No. 10 / 420,302, filed April 22, 2003, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a microbrush and more particularly to an injection molded brush for more predictable cleaning of the root canal system prior to closure during root canal treatment or a root canal treatment procedure. Background technique [0004] After the tooth matures, the pulp is hidden in the structural elements of the tooth. Oftentimes, for a number of reasons, the pulp is irreversibly damaged, leading to inflammation and infection that can adversely affect the health of the tooth, its supporting structures and the patient. From a clinical point of view, as an alternative to tooth extraction, the ideal goal of root canal treatment is to eliminate the pulp, bacteria and associated irritants from the root canal system, followed...

AI Technical Summary

Problems solved by technology

Because of its high softness, root canalists cannot effectively and purposefully scrub the sides of the canal with the brush and therefore cannot completely remove the coating from the canal

Also, due to the flexibility of the wound wire core, brushes cannot be driven with ultrasound

The flexibility of the wire core causes excessive dissipation of the ultrasonic energy before reaching the bristles of the brush
