60 Chapter 3 As Tables 5 and 6 also show, SS and SS + High Med patients did not differ significantly, indicating that no clear distinction could be made between these two groups on the basis of their RODI scores. Together, these results provide important insights into perceived intra-oral dryness in the various dry-mouth patient groups, which differed with regard to the regions they experienced as the most and least dry. Their RODI scores also differed significantly for the various intra-oral regions. The lowest RODI scores indicated that controls and Low Med patients experienced less intraoral dryness and the highest RODI scores that SS and SS + High Med patients experienced more.
