“…The roughness of zirconia is crucial because it increases the contact area with moisture, which could result in low-temperature degradation [33,34]. In addition, a whitening dentifrice reduced the surface roughness of the polished zirconia surface, which corroborated the results from Pinelli et al [12]. The high RDA of a whitening dentifrice was considered to exert a polishing effect on the zirconia surface.…”

“…The toothbrushing procedure involves applying a mechanical force to the tooth surface over a prolonged period [10]. In addition, various dentifrices have been developed for use with toothbrushes, and chemical components and abrasives of dentifrices can chemically and physically affect the surface of brushed teeth [11,12]. The high fluoride concentration in a dentifrice has been reported to diminish the properties of dental ceramics [13,14,15].…”

“…The high fluoride concentration in a dentifrice has been reported to diminish the properties of dental ceramics [13,14,15]. In addition, dentifrices developed for improved tooth-whitening effects affected the optical properties of restorative ceramic materials [12,16]. Based on the abrasive content, toothpastes vary in their abrasion of enamel, as measured by the relative dentin abrasion (RDA) value [10].…”

“…Studies have reported the effects of toothbrushing and dentifrices on various restorations [12,17,18,19]; however, limited studies have investigated the impact of various dentifrices on the monolithic zirconia material. Hence, this study investigated the effects of various toothpastes on the optical properties and surface properties of monolithic zirconia finished by polishing or glazing methods.…”

This in vitro study investigated the impact of various dentifrices on the shade, translucency, gloss, and surface characteristics of polishing- or glazing-finished monolithic zirconia surfaces after simulated toothbrushing. Eighty square-shaped monolithic zirconia specimens were divided into two major groups based on the finishing methods—polished (P) and glazed (G). Next, specimens from the two major groups were categorized into four subgroups: stored in distilled water (DW, control); brushed with a fluoride-free conventional dentifrice (C); brushed with a fluoride dentifrice (F); and brushed with a whitening dentifrice (W). Overall, eight groups were created—PDW, PC, PF, PW, GDW, GC, GF, and GW (n = 10 each). Shade, translucency, surface gloss, surface roughness, crystalline phase, and superficial topography data were obtained. Repeated-measures ANOVA and two-way ANOVA were used for intergroup comparison (all α = 0.05). The color differences (ΔE00) between pre- and posttreatment were 0.3158 (PDW), 0.7164 (PC), 0.7498 (PF), 0.8106 (PW), 0.1953 (GDW), 0.301 (GC), 0.3051 (GF), and 0.4846 (GW). A statistically significant difference was observed among the ΔE00, surface gloss, and surface roughness of monolithic zirconia. Thus, brushing with several dentifrices markedly affects the optical properties and surface characteristics of monolithic zirconia finished with polishing or glazing methods.

“…(14) Even with the higher hardness zirconia blocks, the results found in this study showed that all zirconia specimens brushed with dentifrice subjected to more roughness and surface topography that is agree with some investigators. (39)(40)(41) That is may be attributed to its low temperature degradation that occurs in moist environments. (40,41) Another explanation is probably related to the influence of pH variations and the concentration of fluoride on the zirconia's susceptibility to degradation.…”

Objectives: Purpose of the present study was to evaluate the surface roughness of current ceramics before and after tooth brushing abrasion, using simulated tooth brushing wear testing. Materials and Methods: 40 ceramic samples (Zirconia ceramics, Vita Enamic, Lava Ultimate, & E-max ceramics) were cut from corresponding 4 types of ceramic blocks using microtome, then 40 samples were divided into 4 groups (n=10). Each sample has a fixed dimension about 10 x 10 x 2mm (thickness). The 3-body simulated tooth brushing wear testing was performed using a programmable logic controlled equipment; ROBOTA chewing simulator* integrated with thermo-cyclic protocol, then Surface roughness of each material (Ra) was measured with USB digital surface profile gauge.Results: Total effect of material; regardless to toothbrush wear simulation cycles, totally there was no-significant (p=0.1379 > 0.05) difference between all materials where (Zr ≥ e.max ≥V enamic ≥ L ultimate) with their mean values respectively after 24 months (Zr; 0.25898 ±0.0035, e.max; 0.25428 ±0.0029, V enamic; 0.25413 ±0.0049, L ultimate; 0.25403 ±0.0028). Total effect of toothbrush wear simulation cycles; irrespective of material, totally toothbrush wear simulation cycles did not affect roughness significantly (p=0.8281 > 0.05) difference between all materials where (18 m ≥ baseline ≥ 6 m ≥24 m ≥ 12 m). Conclusions:Brushing of ceramic materials with conventional dentifrices non-significantly increased surface roughness, where results of surface roughness present within the clinically acceptable range, not insult the patient intraorally.(672) Khaled Haggag, et al.

Effects of whitening dentifrice on yttria-stabilized tetragonal zirconia polycrystal surfaces after simulating brushing

Abstract: Brushing Y-TZP with conventional dentifrice increased roughness, while brushing with whitening dentifrice reduced roughness. Neither dentifrice changed the crystallographic phases after brushing.
