Introduction: In restorative dentistry, the faceting of teeth with aesthetic compromise is considered an effective procedure in which the clinician must choose the ideal treatment and select appropriate materials to obtain satisfactory and predictable aesthetic results. In this sense, the use of the Advanced Polymerization System (APS) has advantages, such as aesthetics, durability, degree of conversion and minimal color change. Objective: Demonstrate the aesthetic-functional restoration using adhesive system and composite resin with APS polymerization technology. Case report: A female patient attended the Integrated Clinic of the Faculty of Dentistry of UFRJ with a complaint of blackening of teeth related to ceramic laminates. After clinical and radiographic examination, it was decided to use composite resin veneers. Results: The composite resin veneers associated with the adhesive system promoted an excellent aesthetic result. Conclusion: The improvement of direct restorations with acid etching techniques and the use of new adhesive systems, combined with the constant development and scientific improvement of composite resins, enabled dentists to perform restorations in the most diverse clinical indications.

Objective: Depending on the degree of saturation and time that pigments have been in the dental tissue, teeth with severe color change may have a poor prognosis for bleaching treatment.Case Report: In the reported case, after a careful clinical history and evaluation of clinical case a conservative treatment with composite resin restoration was carried out on superior central incisor with severe darkening. Direct composite resins with different opacity and translucency in association with resin pigments and a conservative technique were used guaranteeing a minimal intervention and giving a natural aspect to the tooth. The use of pigments made possible less wear of dental structure for insertion of the composite resin, mimetizing the restored tooth with the corresponding teeth.Conclusion: It was concluded that in some cases where indirect restorations would be indicated, when different kinds of dental materials and techniques are applied, direct restorative treatment would be a great option for esthetic restorations.

SUMMARY The aim of the present study was to evaluate the effect of 20% and 35% hydrogen peroxide bleaching gels on the color, opacity, and fluorescence of composite resins. Seven composite resin brands were tested and 30 specimens, 3-mm in diameter and 2-mm thick, of each material were fabricated, for a total of 210 specimens. The specimens of each tested material were divided into three subgroups (n=10) according to the bleaching therapy tested: 20% hydrogen peroxide gel, 35% hydroxide peroxide gel, and the control group. The baseline color, opacity, and fluorescence were assessed by spectrophotometry. Four 30-minute bleaching gel applications, two hours in total, were performed. The control group did not receive bleaching treatment and was stored in deionized water. Final assessments were performed, and data were analyzed by two-way analysis of variance and Tukey tests (p<0.05). Color changes were significant for different tested bleaching therapies (p<0.0001), with the greatest color change observed for 35% hydrogen peroxide gel. No difference in opacity was detected for all analyzed parameters. Fluorescence changes were influenced by composite resin brand (p<0.0001) and bleaching therapy (p=0.0016) used. No significant differences in fluorescence between different bleaching gel concentrations were detected by Tukey test. The greatest fluorescence alteration was detected on the brand Z350. It was concluded that 35% hydrogen peroxide bleaching gel generated the greatest color change among all evaluated materials. No statistical opacity changes were detected for all tested variables, and significant fluorescence changes were dependent on the material and bleaching therapy, regardless of the gel concentration.

SUMMARY This clinical study assessed the performance of posterior composite resins applied with the Adper™ Single Bond Plus (SB) and Adper™ Scotchbond SE (SE) adhesive systems and Filtek™ Supreme Plus composite resin, using modified US Public Health Service criteria. A total of 97 restorations were placed in posterior teeth by two calibrated operators. Application of the materials followed manufacturers' instructions. The restorations were evaluated by two examiners at baseline and after one year. Statistical analyses were conducted using the proportion test at a significance level of 5% (p<0.05). All the restorations evaluated (ie, 100%) received an alpha rating for the criteria of marginal discoloration and marginal integrity at baseline. At one year, for marginal discoloration, 64.6% of SB and 61.2% of SE received an alpha rating. For marginal integrity, 72.9% of SB and 77.6% of SE received an alpha rating. The other restorations received bravo ratings for both criteria. None of the teeth that received the restorative systems presented caries lesions around the restorations. A total of eight teeth presented postoperative sensitivity one week after baseline, five with SB and three with SE; the symptom had disappeared one year later. One year later, composite resin restorations using either adhesive system showed satisfactory clinical performance.

Objective: The aesthetics of dental materials is extremely important for the success of oral rehabilitation. Thus, in the present study we evaluated the color stability and the surface degradation of three micro hybrid composite resins after accelerated artificial aging process (AAA). Methods: Were prepared 24 specimens (n=8) for each material: Solidex, Artglass and Cesead, dimensions of Ø 15 mm by 2 mm in thickness. The samples were subjected to color analysis, before and after AAA, in a spectrophotometer according to the CIE L*a*b* parameters, and a sample of each material, was selected for morphological evaluation under scanning electron microscopy (SEM). The data were submitted to one-way ANOVA and Tukey test (α=0.05). Results: Artglass showed higher stability regarding the presence of red and yellow (p<0.05) when subjected to the AAA and fewer of these pigments (p<0.05) when compared to the Cesead and Solidex, which showed the highest luminance stability (p<0.05). ΔE Cesead was the most unstable (p<0.05). All resins analyzed by SEM showed superficial degradation when submitted to the AAA, mainly in resin Cesead. Conclusion: All materials analyzed demonstrate color change and surface degradation, Cesead resin showed the worse results.

SUMMARY In this laboratory study, a composite resin was stained to a visibly discernible level using both coffee and red wine over 14 days (change was considered clinically noticeable and significant when ΔEab*≥2.7). Color change was measured at one, three, seven, and 14 days of staining. Although the nature of color change was different for the two staining solutions, the overall degree of staining (ΔEab*) rendered by either coffee or wine at each time interval was not significantly different (p≥0.05). Four whitening protocols were applied to stained composites. Treatment included applications of distilled water (control), Crest Pro-Health [HD] toothpaste, Crest Whitestrips, Opalescence PF bleach (15%), and application of a fine pumice polishing (Preppies). HD toothpaste and Whitestrips were applied daily for 21 days, Opalescence was applied daily for 10 days, and polishing was applied once. Each of the whitening products, applied in a manner simulating at-home or in-office treatment, was effective in producing color improvements (lightening) over controls (p&lt;0.05), but none of the four treatments produced lightening that was significantly different from the other treatments (p≥0.05). A comparison of final composite color with that measured at baseline showed that Opalescence returned composite color to an acceptable level following exposure to both staining solutions (ΔEab*&lt;2.7), Whitestrips returned color close to baseline for wine-stained composites, and HD paste and polishing permitted residual stain to remain (ΔEab*≥2.7).

We aimed to evaluate the color stability of bulk-fill and conventional composite resin with respect to thickness and storage media. Twenty specimens of a conventional composite resin (6 mm diameter and 2 mm thick) and 40 specimens of the bulk-fill Tetric EvoCeram composite resin at two different thicknesses (6 mm diameter and 2 mm thick or 4 mm thick,n=20) were prepared. The specimens were stored in distilled water during the study period (28 d). Half of the specimens were remained in distilled water and the other half were immersed in coffee solution 20 min/d and kept in distilled water between the cycles. Color changes (ΔE) were measured using the CIEL⁎a⁎b⁎color space and a digital imaging system at 1, 7, 14, and 28 days of storage. Data were analyzed using Two-way ANOVA and Tukey’s HSD post hoc test (P<0.05). Composite resins showed significant increase in color changes by time (bulk-fill > conventional;P<0.001). Coffee exhibited significantly more staining susceptibility than that of distilled water (P<0.001). There was greater color changes with increasing the increment thickness, which was significant at 14 (P<0.001) and 28 d (P<0.01). Color change of bulk-fill composite resin was greater than that of the conventional one after coffee staining and is also a function of increment thicknesses.

Selection Of

The use of Bulk-Fill composite resins to perform posterior restorations has been massified in recent years in the different clinical disciplines of Dentistry.  This may be due mainly to the simplicity in the application technique of this material as it requires its insertion into the cavity preparation in 4-5mm of composite resin thickness, achieving a considerable reduction of clinical working time. Given the existence of different viscosities of this type of composite resins, certain difficulties have been identified before the selection of each Bulk-Fill material related to the possible combinations that can be made between the different brands available in the market, even when they are used with conventional composite resins. The purpose of the following case report, is to present two step-by-step clinical possibilities using initially, compactable Bulk-Fill composite resin in a single increment for the restoration of a second upper molar, and later, through the combination of Bulk-Fill flowable composite resin together with compactable Bulk-Fill composite resin and a high-refractive-index enamel-like conventional composite resin, for a first upper molar.

Purpose:Since conventional composite resins have some disadvantages such as polymerization shrinkage and secondarycaries formation, indirect restorations are preferred in cases where tooth tissue loss is high. The aim of this study is toexamine the water absorption and color change of indirect composite resins in different beverages.Materials & Methods:In the study, 40 specimens (10×2 mm) were arranged from each composite using three indirect(Signum Composite, Signum Ceramis and Gradia Plus) and one conventional (GrandioSO) composite resin. After thespecimens were polished, they were used for water absorption and color change test. The water absorption test wasperformed through keeping them in water for 7 days as specified in ISO 4049:2009. Samples were kept in coffee, tea anddistilled water for 7 days in order to examine color differences. The water absorption and color change values of thecomposite resins at the end of the 7th day were appraised using one-way analysis of variance (ANOVA) and Tukey’s test(p<0.05).Results:While there was no statistically considerable difference between the water absorption data of the indirect andtraditional composite resin materials we used in the study (p>0.05). When the color changes of resin-containingcomposites in water, coffee and tea were examined, traditional composite resin (GrandioSO) showed statistically lesscolor change than indirect composites in water, coffee and tea (p<0.05).Conclusion:Although indirect composite resins showed similar water absorption with conventional composite, theyshowed more color change than conventional composite. The highest color change in indirect composites was seen incoffee solution. Particle size of the indirect composites do not affect water absorption, but the decrease in particle size ofcomposites shows less color change.

Abstract: Color change or discoloration of the tooth surface is an aesthetic problem that is often complained because it reduces one’s confidence in terms of appearance. This problem can also occur on the surface of restorative materials inter alia composite resin. Composite resin is a tooth-colored restorative material that most people favor due to its aesthetic value. This discoloration can occur due to excessive intake of colored beverages like coffee. The treatment used for discoloration is bleaching, but these treatments have side effects. Calamondin (Citrus microcarpa Bunge.) can be an alternative bleaching agent because it contatins citric acid. This study was aimed to determine whether calamondin juice could affect the color change of composite resin soaked in coffee solution. This was a pre-experimental study with a one shot case study design. Samples were 10 composite resins with a diameter of 5 mm and 2 mm thick soaked in coffee solution for 7 days to obtain discoloration and then samples were soaked in calamondin juice for 5 days to whiten the samples. The discoloration was measured by using the CIEL*a*b* method at 60 minutes and 5 days after soaking in calamondin juice. The Friedman test showed significant changes (p<0.05). Conclusion: Calamondin juice affected the color change of composite resin that had been soaked in coffee solution.Keywords: composite resin, calamondin juice, color change Abstrak: Perubahan warna atau diskolorisasi pada permukaan gigi merupakan salah satu masalah estetika yang sering dikeluhkan karena mengurangi kepercayaan diri seseorang. Masalah ini juga dapat terjadi pada permukaan bahan tumpatan gigi, salah satunya adalah resin komposit. Resin komposit merupakan bahan tumpatan yang sewarna dengan gigi yang banyak digemari orang karena nilai estetiknya. Salah satu penyebab perubahan warna yaitu mengonsumsi minuman berwarna secara berlebih seperti kopi. Perawatan yang digunakan untuk masalah diskolorisasi ialah bleaching, namun perawatan ini memiliki efek samping. Jeruk kesturi (Citrus microcarpa Bunge.) dapat menjadi bahan alternatif bleaching karena karena mengandung asam sitrat. Penelitian ini bertujuan untuk mengetahui apakah air perasan jeruk kesturi berpengaruh terhadap perubahan warna resin komposit yang telah direndam dalam larutan kopi.
