“…Samples in group 2 were subjected to Opalescence ® PF (Ultradent Product, South Jordan, UT, USA) 10% CP for eight hours per day, for 14 days according to the suggested wear time of the manufacturer. [9] Samples in group 3 were bleached with Opalescence ® PF (Ultradent Product, South Jordan, UT, USA) 20% CP for two hours per day for a total of 14 days. In groups 2 and 3, prior to each bleaching procedure, the samples were taken out from the distilled water bath, air-dried with an air jet spray for 60 seconds.…”

Objective:Home bleaching agents may not be safe for composite resins. The purpose of this study was to evaluate the effects of 10 and 20% Opalescence® PF home bleaching agents on the surface roughness and hardness of universal nanocomposite (Filtek Z350), anterior nanocomposite (KeLFiL), and nanohybrid composite (TPH 3).Materials and Methods:Fifty-four composite resin samples with 18 samples for each type of composite resin were prepared using acrylic molds (4 × 2 mm). Each type of composite resin was further divided into three groups [n = 6 controls were placed in distilled water for 14 days and the other two groups of n = 6 were bleached with 10 and 20% carbamide peroxide (CP), respectively for 14 days]. Surface hardness of the composite resin was tested with a Vickers hardness tester, whereas surface roughness was tested with atomic force microscopy (AFM).Results:There were significant changes in the surface hardness of KeLFiL and TPH 3. However, all the tested materials showed no significant changes in the surface roughness.Conclusion:After 14 days of home bleaching treatment, there was no adverse effect on the surface roughness of all three composite resins, although the surface hardness for KeLFiL and TPH 3 were significantly reduced.

“…Various functions of saliva are implicated in the maintenance of oral health and the protection of our teeth. [ 26 ] Previous studies carried out by Hila Hajizadeh et al .,[ 27 ] Zuryati et al .,[ 28 ] Kaur and Nandlal[ 29 ] have evaluated abrasion produced on dental materials. However, these studies also had the limitation that the effect of saliva was not evaluated.…”

Aim:The aim was to assess, in vitro, the effect on surface abrasivity of enamel surface caused by three different types (flat trim, zig-zag, bi-level) of toothbrush bristle design.Materials and Methods:Twenty-four freshly extracted, sound, human incisor teeth were collected for this study. The enamel slab was prepared, which were mounted, on separate acrylic bases followed by subjected to profilometric analysis. The surface roughness was measured using the profilometer. The specimen were divided into three groups, each group containing eight mounted specimens, wherein, Group 1 specimens were brushed with flat trim toothbrush; Group 2 brushed with zig-zag and Group 3 with bi-level bristle design. A commercially available dentifrice was used throughout the study. A single specimen was brushed for 2 times daily for 2 min period for 1 week using a customized brushing apparatus. The pre- and post-roughness value change were analyzed and recorded.Statistical test:Kruskal–Wallis test and Mann–Whitney U-test.Result:The results showed that surface abrasion was produced on each specimen, in all the three groups, which were subjected to brushing cycle. However, the bi-level bristle design (350% increase in roughness, P = 0.021) and zig-zag bristle design (160% increase in roughness, P = 0.050) showed significantly higher surface abrasion when compared with flat trim bristle design toothbrush.Conclusion:Flat trim toothbrush bristle produces least surface abrasion and is relatively safe for use.

“…Hajizadeh et al [14] demonstrated that bleaching significantly increased the abrasion of composite resins, and NF composite resin was the most resistant to abrasion, while MH type was the least resistant. Furthermore, one typical pattern to maintain oral health during at-home bleaching procedure is to brush teeth with a toothpaste after removal of the bleaching tray [15].…”

Objectives: This study aimed to evaluate the effect of toothbrushing after application of 15% carbamide peroxide (CP) on the surface roughness of three types of composite resins. Materials and Methods: Twenty samples, measuring 4 mm in height and diameter, were fabricated of three composite resins namely microfilled (MF) Heliomolar HB, nanohybrid (NH) IPS Empress Direct and microhybrid (MH) Tetric Ceram HB. After polishing, the initial surface roughness was measured with a profilometer. The tray technique was used to apply 15% CP gel for 6 hours. Then, cleaning was carried out with an Oral-B electric toothbrush for 3 minutes in a tank containing a freshly mixed toothpaste. These procedures were repeated for 21 days. Then, the surface roughness was measured again and compared with the initial values. A mixed-design ANOVA model was used for the analysis of data (P<0.05). Results: The baseline roughness was significantly lower in MF compared to the NH and MH composites (P<0.001). Roughness increased in all study groups during the intervention period; however, this increase was not significant in the MH group (P=0.17). Furthermore, the increase in roughness in MF was smaller than that in NH (P<0.001) and MH (P=0.02) groups. Conclusions: The effect of intervention was more pronounced on NH and MH groups. Surface roughness changes were minor in MF composite resin.
