“…Roughness studies involving immersion in dental bleaching agents and soft drinks have been performed only on dental enamel, composite resin, acrylic resin and other materials for dental restorations . These studies observed the values of the roughness profile (Ra) and surface characterization (SEM and AFM), concluding that the dental bleaching agents and cola soft drinks induced variations in the surface roughness of the dental materials.…”

“…Regarding the dental bleaching agents, Turker and Biskin observed that 10 and 16% carbamide peroxide gels, which were applied to feldspathic porcelain over a period of 30 days, caused a decrease in the hardness, whereas the roughness increased significantly after the first 2 weeks of the application. Similarly, Abu‐Eittah and Mandour investigated the effect of 30, 35, and 38% hydrogen peroxide on the topography of a dental ceramic and observed by AFM and SEM analysis that the surfaces of all of the specimens had holes, with the 35 and 38% concentrations also exhibiting a significant change in the surface roughness. These results, although obtained for a ceramic substrate, are consistent with those obtained in this work because the Ti discs that were immersed in 35% hydrogen peroxide and 16% carbamide peroxide showed the largest changes in the surface roughness and in the SEM and AFM images compared with the other groups, which maintained characteristics and roughness values close to those of the initial period or control group.…”

“…21 For this reason, it could be speculated that such large consumption of this acidic beverage may cause changes in implant surfaces, which are prone to corrosion. 11 The in vitro investigations of the changes that may occur on the surface of installed dental implants, as reported by Zhoua et al, 14 Oliveira and Guastaldi, 15 and Mareci et al, 16 can be correlated to the studies by Abu-Eittah et al 22 and T€ urker et al, 23,24 which evaluated the effects of hydrogen and carbamide peroxides on the surfaces of restorative materials used in dentistry. To authors' best knowledge no study has evaluated the effect of bleaching agents and cola soft drink on the surface topography of Ti material.…”

The effects of carbamide peroxide, hydrogen peroxide and cola soft drink on the topographic modifications of commercially-pure titanium (CP-Ti) and Ti-6Al-4V were investigated. Ti discs were divided into 18 groups (n = 4) based on the solution treatment and Ti type. Specimens were immersed in 3 mL of each solution for 4 h per day (for the remaining 20 h, discs were left dry or immersed in artificial saliva) for 15 days. For control, specimens were immersed in only artificial saliva. Ti surfaces were examined using scanning electron (SEM) and atomic force (AFM) microscopes and their surface roughness (in µm) and surface chemical modifications were investigated. Data were analyzed by ANOVA and Tukey's test (α = 0.05). Groups immersed in 35% hydrogen peroxide showed the highest roughness (Ra) (171.65 ± 4.04 for CP-Ti and 145.91 ± 14.71 for Ti-6Al-4V) (p < 0.05), followed by groups treated with carbamide peroxide 16% (110.91 ± 0.8 for CP-Ti and 49.28 ± 0.36 for Ti-6Al-4V) and 35% (65.67 ± 1.6 for CP-Ti and 53.87 ± 1.98 for Ti-6Al-4V); treatment with artificial saliva did not affect the results. These values were statistically superior to those observed prior to the treatment and to those of the control group (31.0 ± 0.99 for CP-Ti and 29.95 ± 0.58 for Ti-6Al-4V). Cola soft drink did not alter the surface roughness of either Ti type (p > 0.05). SEM and AFM revealed dramatic changes in the specimens surfaces immersed in the 35% hydrogen peroxide, mainly for CP-Ti. No detectable chemical modifications on the Ti surface were observed. Bleaching agents promoted significant changes in Ti topography, which could affect the longevity of implants treatments.

“…One reason for this is that there might be an increase in release of free radicals from bleaching agents when the temperature rises, thus inducing greater effects on dental materials. 28 Also a previous study 29 presented that surface roughness of a ceramic material increased with increasing HP concentration. In this study the bleaching agents used are at high concentrations (35% and 46%).…”

Objectives: The aim of this in vitro study was to evaluate surface roughness of six different restorative materials during office bleaching procedures with blue light emitted diode (LED) and diode laser photo activation. Materials and Methods:Filtek TM supreme, Tetric Evo Ceram, Tescera ATL, Clearfill Majesty Esthetic, Durafill VS and IPS Empress 2 materials were evaluated in this study. Twenty specimens, 10 mm in diameter and 2 mm thick, were fabricated from each material using a teflon mold. All specimens were randomly assigned to two groups (n=10). Group 1 received two topical applications of 35% hydrogen peroxide for 20 s. And was photoactivated using LED. Group 2 received topical application of 46% hydrogen peroxide using diode laser. Surface roughness values were measured prior to and following bleaching procedures by using a profilometer. Data were analyzed statistically, by one-way-analysis of variance (ANOVA), post-hoc Tamhane's T2 and independent t tests. Results:Surface roughness values for all restorative materials tested increased after both bleaching procedures (p<0.05). Tescera ATL bleached with diode laser photo activation showed higher surface roughness value than LED activation (p<0.05). However, there were no significant differences in two bleaching methods for other restorative materials (p>0.05). Conclusions:Although clinical effects depend on in-vivo conditions, the effects of office bleaching agents should be known and applied cautiously when a colored restoration is bleached or a restoration is neighboured with the tooth bleached.

“…28 After highly concentrated HP application (30%, 35%, 38%), the surface roughness of alumina-reinforced dental ceramic increased significantly with time of immersion as well as with the increase in concentration of HP. 29 The other investigation into the effects of 15% and 35% CP on the surface roughness and whiteness of overglazed and autoglazed low-fusing ceramic, reported that 1-week CP bleaching significantly affected the overglazed ceramic surface. 30 The increased roughness and whiteness of bleached ceramic were possibly due to the reduction of surface SiO 2 content.…”

Available online ---KEYWORDS bleaching; carbamide peroxide; hydrogen peroxide; restorative material Abstract In recent years, there has been an increased demand for improvement in the appearance of natural teeth. The conservative technique of tooth bleaching has gained attention and acceptance from both patients and clinicians. Despite increased popularity, there is controversy surrounding the adverse effects of bleaching on dental restorative materials. This article reviews the effects of bleaching agents on major categories of dental restorative materials and provides evidence-based recommendations to the clinicians and researchers. Current literature reveal that bleaching might have a detrimental effect on restorative materials. However, because of the variability in experimental design, there is a lack of consensus concerning the bleaching effects on restorative materials. A standardized and reproducible guideline for assessment of bleaching effects on restorative materials needs to be established and verified by future studies.
