“…The previous studies also showed no significant difference in composite surface roughness after bleaching using the at-home technique (6,21). In contrast to the present study, Dogan et al (22), reported significant decrease in the surface roughness of composites bleached with 16% CP, while Kim et al (23) showed a minor surface roughness change.…”

“…In the present study, the restorative materials evaluated consisted of small filler particles, though, with the difference in average particle size (Table 1). If the surface roughness was higher than 0.2 µm, the accumulation of plaque was raised, and consequently, the possibility of secondary caries and the occurrence of periodontal disease was increased (6). It was claimed that spherically shaped nano-filler particles gave better polishability to the composite (13).…”

“…The rough surface is more susceptible to staining in the oral cavity (4), and resulting in a negative effect on the aesthetic appearance of the restoration (5). Increased surface roughness is clinically relevant regardless of etiology, as it results in the accumulation of food debris and the formation of a biofilm, which consequently could cause secondary dental caries and periodontal tissue disease as well (6). The surface roughness of dental materials within the oral cavity must be 0.2 µm or less to reduce bacterial retention (7).…”

“…Natural teeth bleaching is an increasingly popular method and during this procedure, carbamide or hydrogen peroxide inevitably comes into contact with existing dental fillings. Peroxide-based products are effective in teeth whitening; however, their effect on the surface roughness of filling materials is controversial (6).…”

Introduction: Composite materials may be exposed to chemicals in food and beverages in the oral cavity, which can lead to changes in surface roughness. The aim of this in vitro study was to evaluate the surface roughness of two restorative materials after exposure to coffee and green tea followed by a dental bleaching procedure. Methods: For nanofilled composite and microhybrid composite, 15 samples each were fabricated. Five specimens from each composite were stored in instant coffee and green tea for 4 h a day. After 30 days of immersion, specimens received dental at-home bleaching, using 16% carbamide peroxide (CP), for 7 h a day. The control group was stored in deionized water for 30 days. Surface roughness was determined by profilometry 24 h after polymerization, after 30 days of immersion, and after bleaching. The data were analyzed using a t-test for paired samples and mixed analysis of variance, at a 0.05 significance level. Results: Neither beverages nor CP treatment significantly altered the surface roughness of the composites. There was no difference between the tested composite materials regarding roughness. Conclusion: Surface roughness of the microhybrid and nanohybrid composites was not modified by coffee, green tea, and subsequent whitening treatment.

“…Surface roughness is a frequently used parameter for evaluating the effect of bleaching products on enamel, as it is an important measurement that determines the propensity of a surface to adhere to foreign materials. Greater enamel roughness generally reflects an increased surface area and favors the adhesion and accumulation of food debris and biofilm formation [41]. The maintenance of tooth color after bleaching is an important aspect of the procedure and is one of the initial inquiries of patients seeking treatment.…”

In-office bleaching with high concentrations of hydrogen peroxide (H2O2) agents causes undesirable alterations in the enamel. Surface pre-reacted glass-ionomer (S-PRG) filler is a functional material known for its acid-neutralizing and demineralization-inhibition properties. This study evaluates the effect of S-PRG filler incorporation in H2O2-based bleaching on the enamel surface. Bovine enamel surfaces were bleached using a bleaching paste formulated with a liquid (35% H2O2) and a powder containing 5% or 10% S-PRG filler. The surface roughness and the Vickers microhardness of the treated enamel surfaces were evaluated. The enamel surfaces were observed under a scanning electron microscope (SEM) and analyzed using energy dispersive X-ray (EDX) technology. The surfaces were challenged by citric acid and observed by SEM. The specimens bleached with the paste containing the S-PRG filler showed lower enamel surface roughness and higher microhardness values than did those bleached with the plain paste (0% S-PRG filler); meanwhile, there were no significant differences between the 5% or 10% S-PRG filler groups. The S-PRG filler groups showed enamel surface morphologies similar to those of the non-bleached enamel, according to SEM observation, and EDX analysis detected the presence of fluoride and strontium ions. The S-PRG filler groups showed a higher resistance to erosion. The S-PRG filler mitigated the detrimental effects of bleaching agents on the enamel surface and provided resistance to erosion.
