Abstract: Shade-matching process that is consistent is the use of shade tabs from various commercially available shade guides. Shade selection is done intraorally with the help of shade tabs and thus contamination with saliva must be assumed. Therefore, shade tabs must be disinfected after each use. The procedure of subjecting the shade tabs in various disinfectants has been suggested to cause a change in the colour of individual shade tab, resulting in compromised shade matching procedures and contribute to the dissatisfaction of clinicians, technicians, and patients. Hence, this study aims at identifying the effect of four commercially available surface disinfectants: sodium hypochlorite (5.2%) and gluteraldehyde (2%), chlorhexidine gluconate (2%), isopropyl alcohol (70%).disinfectants on the colour of shade tabs of two different ceramic shade guides (Vitapan Classic and Ivoclar Chromascop).
