COMPARATIVE EVALUATION OF COMMONLY CONSUMED CATECHU AND CATECHU WITH LIME ON COLOR STABILITY OF THE NANO-HYBRID COMPOSITE - AN IN VITRO STUDY

Abstract

AIM: Comparative evaluation of commonly consumed catechu and catechu with lime on color stability of the nano-hybrid composite.

METHOD: A total of 25 uniform cylindrical disks of 10-mm diameter and 1-mm thickness prepared from the nano-hybrid composite were used in the study. Each sample was randomly divided into three subgroups.

Group 1 (n=10) Catechu, Group 2 (n = 10) Catechu with lime, Group 3 (n =05) Artificial saliva (Control group)

The samples were immersed in each agent for 15 days. Color changes measurements were noted at the baseline and 15th day by two-dimensional profilometer and spectrophotometer, respectively.

RESULTS: It was found that nano-hybrid composite resin showed more color change when immersed in catechu and catechu with lime as compared to the control group. Intergroup comparison showed statistically significant increase in color change in the catechu group followed by the catechu with the lime group and artificial saliva.

CONCLUSION: Within the limits of the present study, it can be concluded that all experimental specimens showed discoloration. At the end of 15th day, among the groups, catechu showed more color change followed by the catechu and lime and the control group.
