The Effect of repeated firing on the Color of Ceramic System with two Different Veneering Porcelain Shades

Journal Title: Journal of Advanced Medical and Dental Sciences Research - Year 2017, Vol 5, Issue 9

Abstract

Statement of problem: Shade matching is an important property in fixed prosthodontics for achieving optimal esthetics. However, there is a lack of information on how color is affected by fabrication procedure. Purpose: To evaluate and to compare the color changes observed after repeated firing (3rd, 5th and 7th) of Pressable ceramic system veneering with two different veneering porcelain shades using spectrophotometer. Materials and methods: Twenty disc-shaped ceramic specimens (10 mm in diameter, with a core thickness of 1 mm), with 2 different veneering porcelain shades (A1, B2), were fabricated from an Pressable ceramic system. Repeated firings (3, 5, and 7 firings) were performed. Color differences (ΔE) and changes in color parameters (ΔL, Δa, Δb) were determined using a spectrophotometer. The statistical analysis was done using Repeated-measures ANOVA. Unpaired ‘t’ and ‘Tukey HSD Post hoc test’ were used for multiple comparison. Results: The results denote that perceptible color changes (ΔE>1) were observed after repeated firing
