The present invention relates to a root canal treatment apparatus for cleaning a root canal, a root canal treatment apparatus for charging a root canal, or a root canal treatment apparatus for cleaning and charging a root canal. The root canal treatment apparatus for cleaning a root canal according to the present invention comprises: a storage container for storing a cleaning liquid or a filler supplied from the outside; an ultrasonic oscillator for applying ultrasonic waves to the cleaning liquid or the filler stored in the storage container; an injection port for injecting, around the root canal, the cleaning liquid or the filler to which the ultrasonic waves have been applied in the storage container; and a nozzle having a suction port for sucking the cleaning liquid or bubbles in the root canal or the bubble.

The present invention provides a dental hydraulic temporary sealing material composition on which a protection of tooth substance, such as tooth substance strengthening and control of secondary dental caries, can be expected by sustained-releasing various ions including a fluoride ion, while having a high initial setting ability. More specifically, the present invention provides a dental hydraulic temporary sealing material composition comprising 65.0% to 85.0% by mass of component (1): a hydraulic inorganic powder; 10.0% to 25.0% by mass of component (2): an organic solvent; 3.0% to 15.0% by mass of component (3): a resin; and 0.01% to 10.0% by mass of component (4): an ion sustained-release glass.

The present invention provides a laminate having excellent bacteria adhesion suppression performance. The present invention also provides a kit and a method for producing a laminate. A laminate according to the present invention includes a base material, an undercoat layer formed of an undercoat layer forming composition containing a polymer containing a repeating unit containing a polymerizable group and a repeating unit containing a polar group, and a cured film formed of a curable composition containing at least one compound selected from the group consisting of a compound represented by Formula (I), a compound represented by Formula (II), a compound represented by Formula (IV), and a compound represented by Formula (V) in this order.

Provided herein are methods and compositions related to bacteria of genus Rothia useful as therapeutic agents for dental caries.

Monochromatic dental shaped body, which has an opacity of from 70 to 78%, and a process for its production.

A dental formulation including: a bioactive glass composition as defined herein, in an effective amount; and a suitable carrier as defined herein, in an effective amount. Also disclosed is a method of making and using the dental formulation to treat, for example, dentin sensitivities.

Methods for identifying a composition that neutralizes toxicity of a lipopolysaccharide are disclosed. The methods comprise comparing the amount of cytokine and/or prostaglandin E2 secreted by cells that have Toll-like receptors activated by a lipopolysaccharide in the presence or absence of a test composition. Methods of neutralizing toxicity of a lipopolysaccharide in an individual's oral cavity using compositions identified neutralizing toxicity of a lipopolysaccharide are also disclosed. Method of neutralizing toxicity of a lipopolysaccharide in an individual's oral cavity using oral care compositions that comprise combinations of zinc oxide and zinc citrate are also disclosed.

A direct filling composite resin restorative featuring a CTE that is similar to dentin and an antimicrobial is disclosed. The exemplary anti-microbial compound is zinc oxide. The CTE of the direct filling composite resin restorative is in the range of 12-15 ppm/° C. The low CTE is achieved by high filler loading of a trimodal distribution of low CTE filler. By maintaining a CTE substantially similar to that of dentin, the “Marginal Percolation” phenomenon is minimized, which decreases the incidence of secondary caries.

A dental adhesive curable composition containing a polymerizable monomer including a polymerizable monomer represented by formula (1′) and defined amounts of an acidic group-containing polymerizable monomer, a polymerization initiator containing a peroxide and a photopolymerization initiator, and a reductant containing a sulfinic acid compound and/or a salt thereof, and a filler: ##STR00001##
wherein the R groups, n and m are defined. A dental adhesive curable kit and a mobile tooth fixing material are also provided.
