“…Corresponding to the present study, Yılmaz et al 32 investigated the color stability of glazed and polished dental porcelains, and they reported that polished porcelain surfaces of low-fusing and ultra-low-fusing porcelain materials had statistically significant color deviations compared to the glazed surface in the same group after immersion in methylene blue. Based on the results of the present study, it was concluded that glazed specimens showed better color stability.…”

Background/purpose: There is a lack of information in the few studies reporting on the stainability of dental porcelain materials. However no studies have been found that investigated effects of polishing methods and staining agents on the color stability of dental porcelains. The purpose of this study was to evaluate the effects of different polishing techniques on the color stability of various dental porcelains. Materials and methods: Fifty-five specimens were prepared for each of feldspathic (Vita VMK 95, Ceramco III), low-fusing porcelain (Matchmaker), and machinable feldspathic porcelain blocks (Vitablocs Mark II). The prepared specimens were divided into 11 groups (n Z 5) representing different polishing techniques including a control (no surface treatment), glaze, and nine other groups which were finished and polished with a polishing disc (Sof-Lex), two porcelain polishing kits (NTI, Dialite II), a diamond polishing paste (Sparkle), a zirconium silicatebased cleaning and polishing prophy paste (Zircate), an aluminum oxide polishing paste (Prisma Gloss), and combinations of these. Specimens were stored for 48 hours at 37 C in a coffee solution. The color of all specimens was measured with a colorimeter before and after exposure, and color changes (DE) were calculated. Data were analyzed with a two-way analysis of variance, and mean values were compared by the Tukey's honest significant difference test (a Z 0.05). Results: When comparing the four different porcelain materials, Ceramco III demonstrated the highest DE value. No significant difference was observed among the porcelain material groups of Mark II, Matchmaker MC, and VMK 95 (P Z 0.074). When comparing the polishing techniques, the lowest DE values were observed in Group Gl for all porcelain materials tested. No significant difference was observed among Groups Sl, Di, and Pk, (P Z 0.883), and these Groups demonstrated significantly higher DE values than Group Gl (P < 0.05).

“…Several studies reported that glaze was superior to other polishing techniques in terms of surface properties and staining resistance 1416171819. Since it is not possible to glaze hybrid resin-ceramics, the main objective of this study was to evaluate some commercially available materials on their effectiveness with comparison to glaze.…”

PURPOSEThe purposes of this study were to evaluate the staining resistance of CAD/CAM resin-ceramics polished with different techniques and to determine the effectiveness of the polishing techniques on resin-ceramics, comparing it with that of a glazed glass-ceramic.MATERIALS AND METHODSFour different CAD/CAM ceramics (feldspathic ceramic: C-CEREC Blocs, (SIRONA) and three resin-ceramics: L-Lava Ultimate, (3M ESPE), E-Enamic, (VITA) and CS-CeraSmart, (GC)) and one light cure composite resin: ME-Clearfil Majesty Esthetic (Kuraray) were used. Only C samples were glazed (gl). Other restorations were divided into four groups according to the polishing technique: nonpolished control group (c), a group polished with light cure liquid polish (Biscover LV BISCO) (bb), a group polished with ceramic polishing kit (Diapol, EVE) (cd), and a group polished with composite polishing kit (Clearfil Twist Dia, Kuraray) (kc). Glazed C samples and the polished samples were further divided into four subgroups and immersed into different solutions: distilled water, tea, coffee, and fermented black carrot juice. Eight samples (8 × 8 × 1 mm) were prepared for each subgroup. According to CIELab system, four color measurements were made: before immersion, immersion after 1 day, after 1 week, and after 1 month. Data were analyzed with repeated measures of ANOVA (α=.05).RESULTSThe highest staining resistance was found in gl samples. There was no difference among gl, kc and cd (P>.05). Staining resistance of gl was significantly higher than that of bb (P<.05). Staining resistances of E and CS were significantly higher than those of L and ME (P<.05).CONCLUSIONCeramic and composite polishing kits can be used for resin ceramics as a counterpart of glazing procedure used for full ceramic materials. Liquid polish has limited indications for resin ceramics.

“…24 In this measuring system, an observer can report on his/her perception of the colour change. 27 In this study, the authors used the CIELAB Colour CIE L*a*b* and NBS systems to assess colour differences of artificial teeth after their immersion in tea, filtered coffee and cola. It was found that the highest NBS unit value was 3?2, a value which describes the colour change as a 'marked change' according to the NBS system.…”

The purpose of this in vitro study was to evaluate the colour changes in six brands of porcelain and of acrylic teeth after their immersion in tea, filtered coffee and cola for 1 day, 1 week, 2 weeks and 4 weeks. The study comprised three brands of porcelain and three brands of acrylic teeth. Five central maxillary incisors from the six types of artificial denture teeth were distributed equally into four groups (n530) according to the four immersion solutions. Colour measurements on each tooth were made before their immersion, and repeated after 1 day, 1 week, 2 week and 4 week immersions in the four solutions using the CIE L*a*b* colour measuring system. The colourimetric data were converted to National Bureau of Standards units. The data were analysed statistically by repeated measures analysis of variance (ANOVA), one-and two-way ANOVA, and Tukey honestly significant difference (HSD) multiple comparison tests. It was found that tea was more chromogenic than either filtered coffee or cola, and that acrylic teeth that had been immersed in tea for 4 weeks displayed the greatest colour change when compared to porcelain teeth. Tea is more chromogenic than filtered coffee and cola. The colour stability of porcelain teeth is greater than that of acrylic teeth. The degree of discolouration of acrylic and porcelain teeth after their immersion in tea, filtered coffee and cola is time dependent.

Color Stability of Glazed and Polished Dental Porcelains

Abstract: It may be concluded that the glazed specimens showed a better color stability, although the staining observed in the polished specimens was not clinically noticeable.
