The prevalence of xerostomia in patients with removable prostheses.

Purpose: The objective of this study was to determine the prevalence of xerostomia among patients attending a dental clinic for provision of dentures and to investigate the oral cleanliness in those patients.

Materials And Methods: Denture-wearing patients who reported dry mouth completed a questionnaire related to xerostomia. Dryness of the mouth was determined by clinical observation.

Evaluation of stain removal and inhibition properties of eight denture cleansers: an in vitro study.

Objectives: To determine the ability of eight denture cleansers to remove and inhibit tea-stain build-up on acrylic resin.

Materials And Methods: In the stain removal study, Perspex(®) (cast heat polymerised resin) specimens previously soaked in saliva were stained using multiple exposures of chlorhexidine and tea solutions. Specimens were exposed for 1 min to one of the eight denture cleansers for five cycles, washed and dried and their optical density read on a uv/vis spectrophotometer at 295 nm.

Energy absorption and hardness of chair-side denture soft lining materials.

The purpose of this study was to evaluate the hardness and energy absorption properties of four commercially available chairside silicone denture soft lining materials and to compare their properties with those of a heat-polymerized silicone denture liner. The denture lining materials investigated were four auto-polymerising silicone soft liners (GC Reline Soft, Ufigel SC, Elite Soft Relining and Tokuyama Sofreliner S) and a heat-polymerised silicone liner (Molloplast B). The soft liners were processed according to manufacturers' instructions.
