ABSTRACT

Background: A provisional restoration is an integral part of successful treatment for fixed prosthesis while the final prosthesis is being fabricated as they provide pulpal protection, maintain periodontal health, occlusal relationship and also help in deciding the shade, shape and contour of the final restoration. Color stability is one of the important properties of these materials. Regardless of composition and polymerization method, these materials tend to undergo color changes and roughness over time. Thus, the purpose of the study is to analyse the impact of temperature change on colour stability of provisional fixed partial denture material after immersion in staining solutions (tea). Methods: Specimens (n=20) with diameter of 20±1mm and 3mm thickness were fabricated from polymethyl methacrylate auto-polymerized resin. Initial color evaluation using CIE L*a*b* system was done by Spectrophotometer and baseline readings were recorded. After baseline readings, staining solutions (tea and synthetic saliva) with their respective temperatures (37⁰C and 57⁰C) were prepared and samples were immersed for 2 weeks. Final color evaluation was done again with the help of spectrophotometer. Results: The highest influence on ΔE was exerted by synthetic saliva + tea at 57 ºC followed by synthetic saliva + tea at 37 ºC, synthetic saliva at 57 ºC and synthetic saliva at 37 ºC. Conclusion: The degree of discoloration of the materials depends on food and temperature. Higher the temperature, more is the discoloration.

Keywords: Provisional restorations, color stability, staining solutions, spectrophotometry.
