Abstract: A test result sheet creation device is provided with: a display unit which displays a test result of a saliva test, and a plurality of comment candidates corresponding to the test result; an input unit which accepts an input of the result of selection from the plurality of comment candidates; and a control unit which associates and stores, in a storage unit, at least one test result and a comment selected from the comment candidates, and creates a test result sheet including the at least one test result and the comment selected from the comment candidates.

Abstract: A pair of ferrules used for a fiber connector has a first ferrule 58a having an optical fiber-inserting hole, and a second ferrule 58b arranged opposite to, and on the same axis as, the first ferrule. The front portion of the first ferrule has a male convex shape, and the front portion of the second ferrule has a female concave shape provided with a fitting section for tightly receiving the male convex shaped structure. A sleeve 54 for connecting the two ferrules for optical fiber inside thereof includes a cylindrical sleeve main body, and a plurality of projections 54a provided on the inner circumferential surface of the main body for supporting the outer circumferential surfaces of the ferrules for optical fiber, the plurality of projections being provided to be rotary-symmetrical with respect to the central axis of the sleeve main body and having the identical height.

Abstract: An oral composition comprising (i) at least one phosphate selected from the group consisting of linear polyphosphates of the formula (I):M.sub.n+2 P.sub.n O.sub.3n+l (I)wherein M represents Na or K and N .gtoreq.2, and cyclic polyphosphates of the formula (II):(M'PO.sub.3).sub.m (II)wherein M' represents Na or K and m.gtoreq.3 and (iii) l-menthol, anethol, or the mixture thereof in an aqueous medium. This oral composition has an excellent antibacterial effect and prevents the development of calculus and periodontal diseases.

Abstract: A dental filling material capable of forming a cured product with improved physical properties comprises a polymerizable monomer to be polymerized upon application, characterized in that the polymerizable monomer comprises a reaction product of two moles of a compound selected from the group consisting of hydroxyalkyl diacrylates and hydroxyalkyl dimethacrylates with on mole of an organic diisocyanate alone or in admixture with another polymerizable monomer. The reaction product may be bis(1,3-dimethacryloyloxy-2-propanetriyl)-N,N'-hexamethylene dicarbamate or bis(1,3-diacryloyloxy-2-propanetriyl)-N,N'-hexamethylene dicarbamate. The reaction product may be used in admixture with trimethylolpropane triacrylate and/or trimethacrylate and (mono-, di- or tri-)ethylene glycol diacrylate and/or dimethacrylate. The reaction product may also be used in admixture with bis-oxyethylenic bisphenol-A diacrylate and/or dimethacrylate and (mono-, di- or tri-)ethylene glycol diacrylate and/or dimethacrylate.
