A newly-recommended method for restoring large cavities is the biomimetic approach of using short fiber-reinforced composite (SFRC) as dentine-replacing material. The aim of the current review was to present an overview of SFRC and to give the clinician a detailed understanding of this new material and treatment strategy based on available-literature review. A thorough literature search was done up to December 2017. The range of relevant publications was surveyed using PubMed and Google Scholar. From the search results, articles related to our search terms were only considered. The search terms used were "short fiber-reinforced composite", "everX posterior", and "fiber-reinforced composite restorations". Of the assessed articles selected (N = 70), most were laboratory-based research with various test specimen designs prepared according to the ISO standard or with extracted teeth; only four articles were clinical reports. A common finding was that by combining the SFRC as a bulk base with conventional composite, the load-bearing capacity and failure mode of the material combination were improved, as compared to plain conventional composite restoration. In the reviewed studies, the biomimetic restoration technique of using SFRC showed promising characteristics, and therefore, might be recommended as an alternative treatment option for large cavities.

“…In addition, they also contain a bioactive ionic resin matrix, and thereby are able to achieve polymerization by both light cure and chemical cure. [10][11][12][13][14][15][16][17][18][19][20][21] Thus, there are three hardening mechanisms involved with the Activa restorative, and release and recharge with calcium, phosphate, and more fluoride ions than glass ionomers. In addition, Activa contains no bisphenol A (BPA), bisphenol A glycidyl methacrylate (bis-GMA), or BPA derivatives.…”

Objectives:The aim of this study was to determine and compare the shear bond strength of activa bioactive restorative with and without adhesive and nano-composite. Materials and Methods:Sixty freshly extracted human premolars were used. The teeth were mounted vertically in a self-cure acrylic cylinder. A high-speed fine diamond disk with copious water spray was used to obtain a flat dentin of the labial surface. One clinician prepared all the teeth.The teeth were divided into three groups twenty teeth each, n=20 Group I : The flat dentin surfaces were acid-etched for 15 sec with 37% phosphoric acid, it washed and dry then application of bioactive composite into a plastic ring measuring 3mm width and 2 mm depth. Each specimen was light cured for 40 sec by LED light cure unit. Group II: The flat dentin surfaces were acid-etched and then two coats of bonding agent was applied over each specimen and light cured for 20 sec. then application of bioactive composite. Group III (Control): The flat dentin surfaces were acid-etched and application of bonding agent then nano-composite applicated into a plastic ring measuring 3mm width and 2 mm depth. Each specimen was light cured for 40 sec by LED light cure unit. All of the specimens were tested for shear bond strength and all of the data were analyzed by One way analysis of variance (ANOVA) and Tukey's post hoc test. Results:Results showed that the highest mean value was detected in Nanocomposite, followed by bioactive composite with adhesive, the mean shear bond strength of Nanocomposite and composite with adhesive was significantly greater than bioactive composite without adhesive (p<0.0001). Conclusions:Nanocomposite showed higher shear bond strength followed by bioactive composite with adhesive, while bioactive composite without adhesive showed the lowest shear bond strength value.

“…"White line" margins, which are considered typical of freshly finished bonded resin bonded composite restorations, are prominently absent, which is most likely owing to low polymerization shrinkage. (23) Contradictory results in previous study that have employed similar techniques for the same material have often provided. This contrast may have resulted from different handling and manipulation of materials.…”

“…The results agreed with those reported in previous studies. (15,23) This might be attributed to Activa Restorative contains glass particles and polyacid components of resin-modifed glass ionomer cements, which undergo the acid/base hardening reaction of all glass-ionomer systems. Also, the ionic resin component which contains phosphate acid groups with antimicrobial properties that improve the interaction between the resin and the reactive glass fillers and enhance the interaction with tooth structure.…”

Background:In clinical practice, the restoration of non-carious cervical lesions is a challenge, because most of the time the cervical margin is located in cementum or dentin. This characteristic makes the cervical margin more susceptible to microleakage, causing marginal stains, postoperative sensitivity and recurrent caries.Aim: To compare the microleakage and bond strength for teeth restored with Activa Bioactive restorative and nanohybrid composite resin Materials and methods: Twenty permanent premolars were selected with class V cavities for microleakage, and 20 permanent premolars were selected for shear bond strength. Microleakage was checked using dye penetration method under digital microscope Universal testing device was used to assess the shear bond strength. Leakage scores, mean and standard deviation values for shear bond strength were calculated from the recorded values. For numerical data student t-test was performed to detect the significance between both groups. For categorical data analysis Chi square test was done.Results; There was non-significant difference between ACTIVA bioactive restorative group and nanohybrid composite resin group in both parameters; leakage and bond strength Conclusion: Based on the results of the present study, the type of restorative material did not appear to have a significant influence on microleakage or bond strength KEYWORD: Active Bioactive, Non-Curious Cervical Lesions, Microleakage (4050)
