“…In agreement with other studies 3,[20][21][22][23] , the SBAP was able to increase the surface roughness even in a nanoparticulate composite.The abrasive jet action, which contains sodium bicarbonate particles, on the restorative material surface was demonstrated by comparison of the groups with and without SBAP at time 2 (after the SBAP jet application). The superficial abrasion of a composite resin leads to the loss of surface inorganic particles, increasing the roughness and it interferes in the reflective ability of the material 20 .…”

“…Although in the present study SBAP did not raise the surface roughness values for composite resin exposed to cigarette smoke, the SBAP was able to increase the staining potential of the cigarette smoke. This result may emphasize the recommendation to perform the re-polishing procedures in composite restorations after they are submitted to SBAP procedure 3 .The SBAP can compromise the aesthetic and longevity of restorations, since the color stability also depends of the surface roughness and it can allow greater biofilm retention on these surfaces 9 . Considering that resins are in constant contact with several substances, pH and temperature variations in the oral environment, studies evaluating the effects of air-polishing in restorations for a long period should be performed.…”

“…The composite resins are widely used in restorative dentistry due to the evolution of aesthetic and mechanical properties, as well as the simplified clinical protocols compared to ceramic restorations [1][2][3] . The development of the chemical composition, inorganic particles distribution and size have provided better physical and mechanical properties, resulting in less surface roughness and better color stability against staining 1,4 .…”

“…The roughness present on resin surface can be detected by the tip of the patient's tongue since 0.3µm 10 . These irregularities are directly associated to the characteristics of the material, as well as the action of instruments used on it 4 , besides several kinds of finishing and polishing procedures and follow-up sessions of aesthetic restorations, that include the use of air-polishing powders 3 .…”

“…The advantages of air-polishing compared to the conventional rubber cup prophylaxis are the fast removal of tooth deposits, less hypersensitivity, lower operator fatigue and better access to pits and fissures 3,11,15 . Furthermore, the sodium bicarbonate particles are less abrasive than particles contained in commercially available polishing pastes or pumice 16 .…”

Aim: The aim of this study was to evaluate the surface roughness and the color stability of nanocomposite exposed to the sodium bicarbonate air-polishing (SBAP) followed by red wine, coffee and cigarette smoke exposure. Materials and Methods: 64 nanocomposite specimens were prepared and allocated in 8 groups: G1 (SBAP + distilled water), G2 (SBAP + coffee), G3 (SBAP + red wine), G4 (SBAP + cigarette smoke), G5 (distilled water), G6 (coffee), G7 (red wine) and G8 (cigarette smoke). The surface roughness was evaluated in three periods: before and after SBAP and after exposuring to agents tested. The color was evaluated according to CIEL*a*b* parameters using reflection spectrophotometer in two moments: initial and 30 days after the exposure to staining agents. Data were subjected to three-way repeated measures ANOVA and Tukey's test (5%). Results: The results showed a higher surface roughness of the nanocomposite submitted only to the SBAP and those exposed to the SBAP followed by exposure to the coffee or wine solution. The previous application of SBAP followed by cigarette smoke exposure did not increase the roughness of nanocomposite. The SBAP procedure just increased the staining for cigarette smoke group. Conclusion: The SBAP increases resin surface roughness, which worsens when there is exposure to coffee and red wine solution. In addition, SBAP may also provide increased staining of nanocomposites exposed to cigarette smoke.

Objective. This study evaluated the effect of immediate or delayed finishing/polishing using different systems on the surface roughness, hardness, and microleakage of a silorane-based composite. Material and Methods. Specimens were made with silorane-based composite (Filtek P90, 3M ESPE) and assigned to the treatments: control (light-cured); aluminum oxide discs (Sof-Lex, 3M ESPE); diamond-impregnated silicone tips (Astropol, Ivoclar Vivadent); aluminum oxide-impregnated silicone tips (Enhance, Dentsply). Half of the specimens were finished/polished immediately and the rest after 7 days. Surface roughness (Ra, μm; n = 20) and Vickers microhardness (50 g; 45 s; n = 10) were measured. Cavities were prepared in bovine incisors and filled with Filtek P90. The fillings received immediate or delayed finishing/polishing (n = 10) and were subjected to dye penetration test (0.5% basic fuchsin, 24 h). Data were analyzed by ANOVA and Scheffe, Kruskal-Wallis, and Mann-Whitney tests (p < 0.05). Results. The finishing/polishing system significantly influenced roughness and microhardness (p < 0.0001). For enamel, microleakage was not affected by the finishing/polishing system (p = 0.309). For dentin, Sof-Lex discs and Astropol points promoted greater microleakage than Enhance points (p = 0.033). Conclusion. Considering roughness, microhardness, and microleakage together, immediate finishing/polishing of a silorane-based composite using aluminum oxide discs may be recommended.

Objectives. This in vitro study was aimed to assess the effect of wet and dry finishing and polishing techniques on the flexural strength and microhardness of different commercial nanoparticle contained composite resins. Methods and Materials. The samples were made of Z250 (microhybrid), Z350 XT (nanofilled), and Z550 (nanohybrid) resin composites. Each group was subdivided into 2 subgroups according to polishing protocols. Subgroup 1 for each composite underwent wet polishing, and subgroup 2 was subject to dry polishing technique. Flexural strength and microhardness of the samples were measured at two different times of polishing (T0 and T24). The flexural strength test and microhardness test were measured by a 3-point bending test using a universal testing machine, and a Vickers machine, respectively. Data were analyzed by Kolmogorov–Smirnov, two-way ANOVA, and Tukey HSD tests. Results. ANOVA showed that the type of composite has a significant effect on flexural strength. Two-way ANOVA showed that, at T0, flexural strength of all composites in the dry technique was higher than in the wet technique ( p = 0.019 ). At T24, Z350 XT had the lowest, and Z250 had the highest flexural strength in both techniques. The time and technique of polishing were also significantly effective on hardness. At T0, hardness was higher in the wet compared to the dry method ( p = 0.008 ). Tukey test showed that, at T24, the hardness of Z350 XT was significantly higher than the other materials in both techniques. Conclusion. Immediate wet finishing and polishing presented lower flexural strength. Delayed dry/wet finishing and polishing significantly enhanced the hardness of the samples.
