In this trial, PK was compared to other three active experimental conditions, including a traditional denture adhesive and two types of oral moisturizers. A negative control condition (fifth condition) was also added to the study. In this study, the following test samples were prepared: denture adhesive for dry mouth (PK; Pitatto Kaiteki Gel®: NISIKA, Yamaguchi, Japan), cream-type denture adhesive (NP; New Poligrip® Sa: Glaxo Smith Kline, Tokyo, Japan), gel-type oral moisturizer (BT; Biotene Oral balance Jell®: T&K, Tokyo, Japan), denture moisturizer (DW; Denture Wet®: DENTCARE, Osaka, Japan). The amount of each coating was 1.5 g for PK, 0.6 g for NP, 1.8 g for BT, and 1.2 g for DW.
