Embodiment Construction

[0039]This invention is described below in reference to various embodiments with reference to the figures. While this invention is described in certain embodiments for achieving this invention's objectives, it will be appreciated by those skilled in the art that variations may be accomplished in view of these teachings without deviating from the scope and spirit of the invention.

[0040]In accordance with the present invention, the inventive absorbent insert comprises a compressed absorbent material that comprises particles as a filler dispersed therein, which improves stiffness / rigidity of the insert, and controls the absorbency of the compressed absorbent material, to result in an insert having a desired absorbency. The insert is shaped and sized for inserting into a tooth cavity (such as a pulp chamber or a root canal space shown in FIG. 1), with acceptable rigidity and absorbent rate.

[0041]In one aspect of the present invention, the absorbent insert is applied as an absorbent poin...

Abstract

An absorbent insert of compressed matrix of absorbent material, including a filler dispersed therein to improve stiffness/rigidity of the insert and controls the absorbency of the compressed absorbent material. The insert is pre-shaped and sized for inserting into a tooth cavity, such as a pulp chamber or a root canal space. The compressed insert expands or swells upon absorbing fluid within the tooth cavity, so as to more completely dry the tooth cavity. The absorbent insert also serve as a substrate of an applicator for medical agent to be applied to a tooth cavity. The absorbent insert is provided (e.g., coated or impregnated) with a medical agent, which medical agent is released into the tooth cavity as the absorbent material absorbs fluid in the tooth cavity.

Description

PRIORITY CLAIM[0001]This application claims the priority of: (a) U.S. Provisional Patent Application No. 62 / 519,129 filed on Jun. 13, 2017; and (b) U.S. Provisional Patent Application No. 62 / 632,394 filed on Feb. 19, 2018, which are fully incorporated by reference as if fully set forth herein. All publications noted below are fully incorporated by reference as if fully set forth herein.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention is directed to absorbent inserts which are used in tooth cavities (including pulp chambers and root canals).Description of Related Art[0003]Dental root canal treatment basically involves three steps: shaping, cleaning, and obturation. Cleaning step involves chemical solution irrigation and absorbent point drying the root canal space. FIG. 1 is a schematic sectional view of a human tooth (e.g., a molar). As shown, the tooth T has a crown (enamel) portion C protruding above the gum G. As shown, in the shaping step, the crown C ...
