Relationship Between the Morphology of Oral Membranous Substances and Oral Wetness in Older Individuals Undergoing Long-Term Tube Feeding in Japan.

Aims: Oral membranous substances in tube-fed patients undergo temporal morphological changes, increasing the risk of asphyxiation. While xerostomia is hypothesized to influence these alterations, its precise relationship with oral wetness and specific morphological stages remains unclear. This study aimed to investigate oral wetness as an indicator of xerostomia and predictor of membranous substance formation.
