Aim: Comparative evaluation of commonly consumed catechu and catechu with lime on
surface roughness and color stability of the conventional nano-hybrid composite.
Methodology: A total of 50 uniform cylindrical disks of 10-mm diameter and 2-mm thickness
prepared from the nano-hybrid composite were used in the study. Each sample was
randomly divided into three subgroups of 20 samples each in two experimental groups
(catechu, catechu, and lime) and 10 samples in the control group (artificial saliva). The …
