An evaluation of color stability of temporary fixed partial denture materials: In vitro study

AUTHOR(S): Dr. Imtiyaz Ahmed Magray, Dr. Waseem ul ayoub, Dr. Tahleel Jan and Dr. Arwah Bashir
ABSTRACT:
Aim: To evaluate and compare the color stability of three methyl methacrylate based auto-polymerized resins (DPI Self-Cure Tooth Moulding Powder, Unifast Trad, Structur 2SC/QM) and two composite based bis-acryl auto-polymerized resins (Luxatemp Fluorescence, Integrity) after immersion in synthetic saliva and tea, synthetic saliva and cold beverage, synthetic saliva and chlorhexidine mouth wash, and synthetic saliva (control) for one week, two weeks, four weeks, six weeks and eight weeks.
Materials and Method: 20 samples were made from each material and spectrophotometry was used to evaluate and compare colour stability of temporary fixed partial denture materials.
Results: One-way inova and friedmans test was used in this study the results indicated the presence of strong interaction between material and storage solution regardless of the aspect of Color considered (p< 0.05 for ΔE, ΔL*, Δa*, and Δb*). This is evidence that the material and solution were not additive in effects. Furthermore, the data presented strong evidence (p< 0.001 for ΔE, ΔL*, Δa*, and Δb*) that the pattern of changes differed over time.
Conclusion: Maximum discoloration was seen in case of Unifast trad followed by Stuctur 2SC/QM, DPI self-cure tooth moulding powder, Luxatemp Fluorescence, and Integrity after exposure to synthetic saliva & tea, synthetic saliva & cold beverage, synthetic saliva & chlorhexidiene, and synthetic saliva solutions in comparison to baseline measurement for all the time periods. Integrity is the best material out of all five, if provisional restoration has to give for longer duration in the esthetic region.
