Definitions

  • the present invention relates to a single paste-type hydraulic filler composition, more specifically, a single paste-type dental, characterized in that it quickly cures by absorbing moisture from the surrounding liquid or air, including hydraulic cement and non-aqueous liquid It relates to a hydraulic filler composition.
  • Endodontics is a specific field of dentistry related to the treatment of dental pulp or pathologic tissue.
  • the teeth contain nerves and vascular tissue called pulp inside, covering dentin covering the pulp, and the hardest enamel on the outermost, usually in the root canal treatment.
  • Root canal treatment of teeth with pulp tissue where inflammation is progressing or necrosis is generally carried out through the access cavity formed in the crown to access the internal space of the tooth called the pulp chamber. This is done by opening the root canal treatment instrument into the root canal inside the root.
  • the root canal is sealed using a root canal filler to prevent secondary infection.
  • the ideal dental canal filler is biocompatibility, bactericidal property, sealing property and stability ( It is desirable to have excellent properties such as stability, workability, implanted and distributed properties, and radiopacity.
  • Root canal treatment with guttapercha and sealer can be seen as a conservative treatment. It is usually used in two ways, one is lateral pressurization and the other is vertical pressurization.
  • Lateral pressurization is a method in which a giant perch cone is placed inside the root canal and pressurized laterally with a mechanism called a spreader to fill the root canal, and the void space between the filled giant perch and the root canal is filled with a sealer.
  • Vertical pressurization is a method of filling a root canal by inserting a giant perch into the root canal and pressing it in a vertical direction with a tool called a plugger.
  • MTA Mineral Trioxide Aggregate cements
  • MTA cements are known as materials with excellent biocompatibility and sealability. It can be used for apical refilling and perforation closure, and can be used for pulp capping, pulpotomy, artificial apical barrier placement, revascularization and apexogenesis procedure. It is established as a representative dental material used in such procedures. Therefore, various efforts have been made to fill the root canal using MTA cement which is hardened by water and has excellent sealing property in a humid environment, and as a part thereof, studies on making MTA cement in paste form have been actively conducted. In this regard, for example, the technique of Korea Patent Publication No. 10-2010-0037979.
  • root canals are generally assumed to be a humid environment
  • many dentists are accustomed to drying root canals during root canal treatment, so not all root canals are always in a wet condition, and conventional MTA cement products are root canals.
  • It is cumbersome to use because it needs to be mixed with the liquid just before it is injected into it, and has the disadvantage of requiring a long time to be placed deep in the root canal due to its relatively poor flow and operability.
  • the inventor (s) proposes a single paste-type MTA cement that absorbs ambient moisture even within a dried root canal and reliably cures in an appropriate time.
  • the present invention aims to solve all the above-mentioned problems.
  • Another object of the present invention is to provide a single paste-type dental filler composition which may be provided in a syringe without requiring a separate mixing process.
  • a single paste dental hydraulic filler composition comprising a hydraulic cement, a non-aqueous liquid having hygroscopicity, and a radiopaque material.
  • a single paste dental filler composition which can be provided in a syringe without requiring a separate mixing process.
  • a single paste-type dental filler composition which is easily cured and is easy to three-dimensionally seal the perforated portion of the root canal or tooth and has excellent biocompatibility.
  • a single paste dental filler composition which can be easily cured by absorbing moisture from tissue fluid or air in or around the wet cotton or root canal.
  • a safe single paste dental filler composition that does not require heat and pressure.
  • the filler composition according to the present invention may include a hygroscopic hydraulic cement having high biocompatibility and sealing property, which is cured by absorbing moisture in or around the root canal.
  • Hydraulic cements may comprise calcium oxide or calcium hydroxide as the active ingredient, preferably portland cement or pozzolane cement.
  • portland cement that is similar in physical properties and chemical composition to MTA and has good biocompatibility.
  • D50 average particle size of the hydraulic cement
  • calcium chloride having hygroscopicity and degradability may be further added to the hydraulic cement in order to improve the hygroscopicity of the paste to enable fast and reliable curing, while maintaining biocompatibility and improving hermeticity.
  • pozzolane cement which includes active silica material in portland cement and uses water as the crystallized water in the hydration process as in the following formula (About the construction of such pozzolane cement)
  • the composition intended in the present invention can be achieved without the addition of calcium chloride with the help of the crystal water produced by the above formula.
  • composition according to the invention may comprise a non-aqueous liquid having hygroscopicity in order to paste the hydraulic cement.
  • non-aqueous liquids may contain substantially minimal water that does not substantially cause or harden water that reacts with the hydraulic cement to cause hydration.
  • it may be desirable to include up to about 3% by weight of water relative to the non-aqueous liquids.
  • biocompatibility, storage stability, hygroscopicity, surface activity, easily mixed with water, and quickly absorbed into the human body may be required.
  • Non-aqueous liquids with the above characteristics include N-methyl-2-pyrrolidone (ie, "NMP"), polyoxyethylene sorbitan monolaurate, dimethyl iso Group consisting of dimethyl isosorbide, diethylene glycol dimethyl ether (diglyme) (or diethylene glycol monoethyl ether (Carbitol Cellosolve)) and butylene glycol It may include at least one selected from, and may preferably include NMP.

If the content is less than 15% by weight, it is difficult to secure proper flowability. If the content is more than 35% by weight, the flowability is too large and the hydration reaction may be hindered.
  • composition according to the present invention comprises at least one material selected from the group consisting of radiopaque materials such as barium sulfate, zirconium oxide, bismuth oxide, tantalum oxide and calcium tungstate for ease of reading.
