“…Radiopacity is a desirable property of dental materials, including direct-filling restorative materials (1-3, 5, 10-15), cavity liners (11)(12)(13)(14), core build-up materials (12,16), luting agents (3,13,(16)(17)(18)(19)(20), adhesive systems (21), root canal filling materials (10,22), provisional crown and bridge materials (23), and ceramic restorative materials (24,25). The localization of radiolucent dental materials may not be detected if they are aspirated or impacted in the soft tissue because of trauma or iatrogenic reasons (7,26,27).…”

“…Several studies have revealed that the radiopacity level of dental materials is critical and should depend on the purpose of the dental restorative material being used (3,6,20,24). On the other hand, highly radiopaque materials may cause a Mach effect and result in false positive or negative discrimination (30).…”

“…In dental restorations, the radiopacity level should be within the range of the radiopacity of the dental structure that is being restored. In other words, if the restored part is dentin or an enamel layer, the radiopacity of the restorative material should simulate the conditions of the layer that it is replacing (24,31).…”

“…Due to their reinforcing and crystalline additives (leucite, alumina, magnesia, magnesium aluminate, lithium disilicate, zirconia, and sanidine) and required reinforcement procedures, ceramics possess different radiopacities (24,25,33,(55)(56)(57)(58)(59)(60)(61)(62)(63)(64)(65). Yttria-stabilized tetragonal zirconia polycrystalline (Y-TZP) ceramics have the same high levels of radiopacity as metals such as Cr-Ni alloy and gold (24).…”

Context: This study aimed to provide an overview of the literature on the radiopacity of dental materials in order to emphasize its importance. Evidence Acquisition: English-language literature was investigated using manual and electronic searches for the terms "radiopacity," "dental material," "cement," "composite," "ceramic," "endodontic root canal sealer," "bone graft," and "acrylic resin" in the databases of Medline, google scholar, and Scopus up to April 2016. Seventy-nine selected publications, including review articles, original articles, and books, were evaluated. Results: The radiopacity of different dental materials may be lower or higher than that of the replaced tissue depending on the restorative material used. The research revealed that highly-radiopaque materials should not be used in dental restorations, except as bone graft and endodontic root canal filling materials. For most of the dental restorative materials, moderate radiopacity within the range of the replaced dental tissue is recommended. However, the lower radiopacity of polymer-based restorative or prosthetic dental materials is still a significant clinical problem. Conclusions:The author recommends using highly-radiopaque materials whenever possible for treatment of bone defects and root canals. For dental materials that replace clinical crowns, the radiopacity should be within the range of that of the replaced tooth structure (dentin or enamel). The radiopacity of dental cements should be much higher than that of the enamel in order to facilitate detection of the thin cement remnants.

An iodine‐containing mono‐methacrylate 1‐(methacryloxy‐2‐ethoxyamino‐ carbonyl)methyl‐2‐iodine‐benzene (MEMIB) was synthesized as a radiopacified agent and incorporated into Bis‐GMA/TEGDMA resin system with the aim of preparing a radio‐opaque dental resin system. Double bond conversion (DC) was determined by FT‐IR analysis. Volumetric shrinkage (VS) was measured through a variation in density before and after irradiation. Water sorption (WS) and solubility (SL) were obtained until the mass variation of polymer in distilled water was kept stable. Flexural strength (FS) and modulus (FM) were measured using a three‐point bending set up. Bis‐GMA/TEGDMA without MEMIB was used as control. ANOVA analysis revealed that MEMIB could endow dental resin with radiopacity, and radiopacity increased with the increasing of MEMIB concentration. Compared with the control resin, resin with MEMIB also had advantages like higher DC, lower VS, lower WS, and higher FS and FM. All of these implied that MEMIB had the potential to be used as a radiopacified agent and to be applied in dentistry.

Amelogenesis imperfecta: review of diagnostic findings and treatment concepts

Mineralization defects like amelogenesis imperfecta are often of hereditary origin. This article reviews the diagnostic findings and summarizes the suggested treatment approaches. Currently, there are no defined therapy recommendations available for patients suffering from amelogenesis imperfecta. The mentioned therapies are more or less equal but no comprehensive therapy recommendation is evident. When treating patients suffering from amelogenesis imperfecta, a comprehensive therapy of almost every dental discipline has to be considered. The earlier the diagnosis of amelogenesis imperfecta is confirmed, the better the outcome is. Optimal treatment approaches consist of early diagnosis and treatment approach and frequent dental recall appointments to prevent progressive occlusal wear or early destruction by caries. Full-mouth prosthetic treatment seems to be the best treatment option.
