PROBLEM TO BE SOLVED: To prevent the occurrence of waste of dental filling materials accompanied with color tone confirmation work in the dental treatment.SOLUTION: A syringe for dental filling materials as well as a cylindrical body distal end for use in the same and a ring-shaped cap are configured as follows: at least a cylindrical body is included; at least one surface selected from an inside surface 44A and outside surfaces 44B, 44C of the cylindrical body distal end forming a portion in the vicinity of a discharge port of the cylindrical body is color-coded in areas different to each other with two or more color tones along a circumferential direction C1 of the cylindrical body distal end; a first area of the two or more areas has a first color tone (I) in which a {(a)+(b)}value is 3 or less and the Lvalue is 30 or less in Labcolor system standardized in JISZ8729; and a second area thereof has a second color tone (II) in which the {(a)+(b)}value is 11 or less and the Lvalue is 90 or more in the Labcolor system standardized in the JISZ8729.SELECTED DRAWING: Figure 6【課題】歯科治療時の色調確認作業に伴う歯科充填材料の無駄の発生を抑制すること。【解決手段】筒体を少なくとも備え、筒体のうち吐出口近傍の部分を成す筒体先端部の内側面44Aおよび外側面44B、44Cから選択される少なくとも一方の面が、筒体先端部の周方向C1に沿って2以上の色調が互いに異なる領域に色分けされ、2以上の領域のうち第一領域が、JISZ8729で規格されているL*a*b*表色系における{(a*)2+(b*)2}1/2値が3以下、かつ、L*値が30以下の第一色調(I)を有し、第二領域が、JISZ8729で規格されているL*a*b*表色系における{(a*)2+(b*)2}1/2値が11以下、かつ、L*値が90以上の第二色調(II)を有する歯科充填材料用シリンジならびにこれに用いる筒体先端部およびリング状キャップ。【選択図】図6
