A review article has been conducted including the main research results and comments referring to flowable dental polymeric materials. To begin with, the synthesis and composition of this category of composites is discussed, revealing the major components of the commercial products in terms of chemistry and proportion. Later, the polymerization characteristics are unfolded regarding the reaction time and rate, volumetric shrinkage and depth of cure for both photocurable and self-curable composites. To continue, some perspectives of the pre-treatment or accompanying processes that a clinician may follow to enhance the materials’ performance are described. Fluidity is certainly associated with the progress of polymerization and the in-depth conversion of monomers to a polymeric network. Last, the aspects of radiopacity and translucency are commented on, showing that all flowable polymeric composites satisfy the radiography rule, while the masking ability depends on the fillers’ properties and specimen thickness. The reviewing article is addressed to all field scientists and practitioners dealing with flowable dental composites studies or applications.

“…Three disc-shaped (5 mm diameter, 2 mm thick) samples were prepared using a mold for each tested material (n = 3). 24,32 Composite resins were placed in a single increment and polymerized with a LED (light-emitting diode) curing unit (1200 mW/ cm 2 , Blue Lex GT-1200, Monitex, China) according to manufacturers' instructions. A Mylar strip was placed before a glass slide was applied to flatten the surface before light irradiation.…”

“…The evaluation of the radiopacities of restorative materials consists of enamel, dentin, and aluminum (Al) comparisons 20–23 . According to the ISO 13116 specifications, the radiopacity of restorative materials should be equal to or higher than that of the same aluminum thickness, 12 which is similar to that of human dentin 24 . It is reported that to detect secondary caries, a higher radiopacity than human enamel is required for restorative materials 25 …”

ObjectiveThe aim of this study was to evaluate the radiopacity of single‐shade composite resins with group and multi‐shade composite resins via a digital image analysis.Materials and MethodsDisc‐shaped (5 mm in diameter, 2 mm in thickness) specimens were prepared with one multi‐shade (Estelite Sigma Quick‐ESQ), four single‐shade (Omnichroma‐OC, Charisma Topaz One‐CTO, Vitra Unique‐VU, and ZenChroma‐ZC), three group‐shade (G‐aenial Achord‐GA, Optishade‐OS, and Estelite Asteria‐EA), and one posterior composite resin (Estelite Posterior‐EP) (n = 3). A radiographic image of all the specimens, an aluminum step‐wedge, and a 2 mm thick tooth section were taken. Mean gray values (MGV) of the specimens, enamel, and dentin were calculated by ImageJ software. Composition analysis was performed with EDS, and SEM images (×10,000) were obtained. The data were analyzed with Kruskal‐Wallis and Post hoc adjusted Bonferroni analysis (p = 0.05).ResultsThe mean MGV of CTO, the highest of all test groups, was significantly higher than OC and dentin (p = 0.04 and p = 0.009, relatively). The lowest mean MGV was also observed in a single‐shade group, OC. EDS analysis showed that the tested materials comprised various radiopaque elements.ConclusionsAll of the single‐shade and group‐shade groups exceeded the MGV value of dentin, which is clinically expected from any restorative material.Clinical SignificanceThe radiopacity properties of various single‐shade composite resins which as a category is a rising trend in esthetic dentistry were investigated. It is important for clinicians to be aware of novel materials' physical qualities including radiopacity, a daily clinical criteria for restorative materials.
