A comparison of three hard chairside denture reline materials. Part II. Changes in colour and hardness following immersion in three commonly used denture cleansers.

Abstract

This study investigated the effects of daily use of three denture cleansers on three hard chairside reline materials over a 6-month period. Two controls were used; one dry and one involving storage in water. Colour and hardness were measured at 0 (baseline) and 6-months. There was no significant colour change with Tokuso Rebase Fast Set. Coe Kooliner and Total Hard changed colour more with the short acting peroxide cleanser (Steradent 3 Minutes) than with the overnight peroxide cleanser (Steradent Fresh) and the hypochlorite cleanser (Dentural). The hardness of all materials remained unchanged over the whole test period.
