Effects of Two Types of Denture Adhesive on Oral Function
Objectives: The objective of this study is to clarify the effect of two types of denture adhesives (DA), cream and liner, on oral function.
Methods: Firstly, questionnaire surveys had done on the Internet. Then some people were selected for further investigation (Inclusion criteria: Use denture with denture adhesive; agree face to face to inspect. Exclusion criteria: serious systemic diseases;). The further investigation includes masticatory performance, moisture, and hygiene were evaluated by color-changeable chewing gum (Masticatory Performance Evaluating Gum XYLITOL; Lotte Co., Ltd.,), oral moisture-checking device (mucus; YOSHIDA Co., Ltd.), and the inspection of tongue-coating by dentists. The difference of masticatory performance with or without DA, and the difference of moisture and hygiene in cream and liner, were analyzed statistically. This research was conducted in collaboration with Kobayashi Pharmaceutical Co., Ltd. The study protocol was approved by the Ethics Committee of Tokyo Medical and Dental University (D2018-057).
Results: From the online survey, the number of valid replies was 318. Among them, 54 people (Cream:39, Liner:14) agreed with further investigation. There is a significant difference in masticatory performance with and without DA. However, when separating the two types, cream or liner, there is no significant difference in masticatory performance. There is no significant difference in the moisture and hygiene between cream and liner.
Conclusions: DA tends to have better masticatory performance, but there is no significant difference when divided into cream and liner respectively. Though there is no significant difference in the moisture and hygiene between cream and liner, for cream user, their hygiene tends to be worse. Because the sample size of liner was small, no significant difference was found. Calculating from measurement values in this study, the required sample size was 38 people. More subjects will be added in the following survey.
