| Outline of Final Research Achievements |
To develop a new denture adhesive with antifungal and easy removability, the effects of the components of denture adhesive and powder liquid ratio on viscosity, adhesion strength and operability were examined. The results suggested that the higher the proportion of sodium carboxymethylcellulose and the higher the powder liquid ratio were, the higher the viscosity and the adhesion strength were. And the rate of increase of adhesion strength was low with higher viscosity. With regard to the result of operability, the viscosity that was considered to be appropriate by sensation was around 100 Pa・s.

| Academic Significance and Societal Importance of the Research Achievements |
現在一般的に市販されている義歯安定剤の問題点として、強すぎる粘着力や誤嚥性肺炎の主要原因菌種であるC.albicansがある。これらを改善する新規の義歯安定剤の開発のため、本剤の成分および粉液比がさまざまな物性に及ぼす影響について明らかにすることができた。本研究により得られた結果は、抗真菌性および易除去性を有する義歯安定剤の開発の足掛かりとなる。
