Abstract
AbstractBackgroundDifferences in the effects of cream‐type denture adhesives and home liners remain unclear.ObjectiveThis cross‐sectional study aimed to clarify the differences in the oral‐hygiene status and masticatory performance between participants using cream‐type denture adhesives and those using home liners.MethodsMasticatory performance with and without cream‐type denture adhesives and home liners was evaluated using colour‐changeable chewing gum. Oral hygiene was assessed using the tongue coating index (TCI). Propensity‐score matching was performed using oral moisture, presence of palatal or mandibular protuberances, type of residual ridge, denture type (complete or partial denture), and denture retention as background factors. Wilcoxon signed‐rank test was used to examine the differences in masticatory performance with and without cream‐type denture adhesives and home liners and differences in masticatory performance and TCI between the cream‐type denture adhesive and home‐liner groups.ResultsThis study included 38 and 40 cream‐type adhesive and home‐liner users, respectively, and 17 pairs were obtained after propensity‐score matching. The Wilcoxon signed‐rank tests showed that masticatory performance was significantly different with and without the use of home liners, and higher values were obtained with the use of home‐liners. However, the cream‐type denture adhesive and home‐liner groups showed no significant differences in terms of the change in masticatory performance with the use of them. Furthermore, Wilcoxon signed‐rank tests showed that TCI values were significantly high in the cream‐type adhesive group.ConclusionThe findings in this study suggest that home liners improve masticatory performance and that participants regularly using cream‐type denture adhesives have poorer oral hygiene.
