Abstract

Microporosity in glass ionomer cement contributes on its colour stability. In oral
cavity GIC interacts with saliva, foods, drinks, and the oral hygiene condition which
could affect in colour stability. This study aimed to examine the colour change in GIC
after immersion in black tea solution. Twenty eight disc specimens (6 mm diameter
and 1 mm thickness). The colour measurements were recorded after storage in closed
tube for 24 hours. Specimens were randomly devided into 4 groups of 7 specimens.
Control specimens were kept in saline solution. The other 3 groups were immersed in
black tea solution for 5 minutes respectively for 5, 7, and 14 times, followed by colour
change measurement. Data were submitted to one-way ANOVA and LSD. There was
significant colour change in GIC after immersion in black tea. The conclusion is
longer GIC immersed in black tea lower the intensity. The lowest intensity changing
was the immersed for 5 minutes, 14 times daily.
