“A Comparative Evaluation of The Wettability of Four Denture Base Materials to Three Commercially Available Saliva Substitute: An in Vitro Study”

Abstract

ABSTRACT:
 AIM: The purpose of this study was to compare the wettability of three saliva substitute (Saleva, Wet Mouth and GC Dry Mouth) to four denture base materials (Heat cured, High Impact, Nylon and Cobalt – Chromium metal base).
 Materials and Methods: A total of 60 samples were made, 15 each of the four denture based materials used that are Heat cure PMMA, High impact PMMA, Nylon based denture base and cobalt chromium based denture base. Three commercially available saliva substitutes Saleva, Wet Mouth and GC Dry Mouth were taken to compare the wettability of the denture base materials with the help of Contact Angle Goniometer.
 Results: According to the result derived from this study, the nylon based denture base material was the most easily wettable denture base material while the greatest hysteresis value was offered by Wet Mouth saliva substitute.
 Conclusion: 1. It was concluded that the nylon based denture base material was most easily wettable denture base material and Wet Mouth offered the greatest hysteresis value. 2. It was also concluded that the combination of nylon based denture base material and Wet Mouth offered the greatest retention.
