PROBLEM TO BE SOLVED: To provide a composition for an indicator, that easily adheres to oral mucosa, has a proper viscosity in an oral cavity environment, can be properly spread between an oral mucosa surface and a denture base, and easily specifies an affected part.SOLUTION: The composition for an indicator which is used for detecting pressure points on denture includes: (A) a fatty acid ester having a melting point of 30 to 50°C (B) a water-soluble high polymer and (C) a metal oxide. More preferably, the composition includes: (A) 40 to 95 wt.% of the fatty acid ester having a melting point of 30 to 50°C (B) 1 to 59 wt.% of the water-soluble high polymer and (C) 0.1 to 50 wt.% of the metal oxide.COPYRIGHT: (C)2012,JPO&INPIT【課題】 口腔粘膜に付着して留まり易く、口腔内において適度な粘性を持ち、口腔粘膜面と義歯床との間で適度な拡がりを示し、患部の特定が容易な床過圧部診査用組成物を提供する。【解決手段】A)融点が30~50℃にある脂肪酸エステルB)水溶性高分子C)金属酸化物を含む床過圧部診査用組成物、好ましくは、A)融点が30~50℃にある脂肪酸エステル:40~95重量%B)水溶性高分子:1~59重量%C)金属酸化物:0.1~50重量%を含む床過圧部診査用組成物とする。【選択図】 なし
