Abstract

STATEMENT OF PROBLEM: Recently, as patients'expectation and interest for esthetics are increasing, concerns of esthetic restoration for removable dentures as well as fixed prosthodontics are also increasing. And the color stability of artificial teeth will affect a long term success rate of the denture. But the stain or discoloration of these artificial teeth as well as denture resin has caused esthetic problem. PURPOSE: This study was designed to evaluate the influence on color stability of artificial teeth when soy sauce, red pepper paste and coffee which many Koreans have eaten were applied. MATERIAL AND METHODS: For artificial teeth type (Endura Anterio(R), Physio Duracross(R), Trubyte Biotone(R)) selected for the study, 10 specimens each were soaked into individual beakers of soy sauce, red pepper paste, coffee and distilled water. And L*, a*, b* value were measured for evaluation of the color difference (delta E*) with spectrophotometer on the 1 day, 1 week, 2 weeks, 4 weeks and 8 weeks after immersion.
RESULTS
1. delta E* value of artificial teeth which were soaked in soy sauce and coffee was various according to soaking periods. However there was significant difference between Trubyte Biotone(R) and Physio Duracross(R) in red pepper paste regardless of soaking period (P < .05). 2. Except for 8 weeks of Endura Anterio(R), 4 weeks and 8 weeks of Physio Duracross(R), artificial teeth soaked in red pepper paste regardless of the type had significant difference of _E* value compared with other groups (P < .05). 3. a*, b* value of Endura Anterio(R) and Trubyte Biotone(R) which were soaked in red pepper paste had significant difference compared with the value of other group (P < .05).
CONCLUSION
Red pepper paste had the greatest effect on color difference of artificial tooth. Physio Duracross(R) showed relatively less color difference than Trubyte Biotone(R) and Endura Anterio(R). But as delta E* difference were all less than 3.3, these artificial resin teeth seemed appropriate for clinical use.
