PROBLEM TO BE SOLVED: To provide a root canal treatment-purpose tooth model, enclosing member and tooth mode that prevent a curving state of a pseudo root canal or direction thereof from being visually observed upon cutting the pseudo root canal, and enable the cut pseudo root canal to be easily and accurately evaluated.SOLUTION: A root canal treatment-purpose tooth model 1 comprises: a tooth model 2 that is formed of transparent material, and has a pseudo root canal 23 imitating a root canal in a tooth internally provided； and a housing case 3 that is formed of a non-transparent material, and is removably enclosed with respect to at least a downward lateral face of the tooth model 2.SELECTED DRAWING: Figure 1【課題】疑似根管の切削時に前記疑似根管の曲がり具合や方向を目視することを防止できるとともに、簡単かつ正確に切削した疑似根管を評価できる根管治療用歯牙模型、囲み部材、及び歯牙模型を提供することを目的とする。【解決手段】 透明材料で形成されるとともに、歯牙における根管を模した疑似根管２３が内部に設けられた歯牙模型２と、不透明材料で形成されるとともに、歯牙模型２の少なくとも下方側面に対して取り外し可能に囲まれた収納ケース３とで構成された根管治療用歯牙模型１【選択図】図１
