“…The authors concluded that reduction in the amount of radiopaque substances in the sealers led to a decrease in radiopacity. Several other studies have evaluated the radiopacity of composite resin materials using an aluminum step-wedge as a comparison standard (13)(14)(15).…”

“…The radiopacity of dental materials is important in order to distinguish dental restorative materials from other tooth and surrounding structures (1)(2)(3). It is also a valuable tool for assessing the absorption of materials in bone structures (4).…”

“…The moderate radiopacity of ceramic materials facilitates the diagnosis of secondary caries under the restoration and enables observation of the periodontal effects of the overhangs (2,18). Moreover, the radiopacity of these materials aids localization following the accidental swallowing of fixed or removable dental prostheses and interim crowns (7).…”

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.

“…[16] A radiopaque restoration allows for easy distinguishing of existing restorations and primary caries, evaluation of contours, overhangs and major voids in restoration, and also helps in the identification of recurrent caries. [171819202122] Too high or too low radiopacity are both undesirable for a radiographic diagnosis. Several studies have suggested that the radiographic detection of caries is improved if radiopacity of the restorative material is similar or slightly greater than that of enamel.…”

Introduction:Comparing ante-mortem and post-mortem dental data is a principal method of identification in forensic odontology. Radiographic images of amalgam have been used in dental forensics for identification due to their unique appearance.Aim:The aim of this study was to investigate whether radio-opaque composite restorations have a potential for identification in forensic odontology.Materials and Methods:Thirty typodont mandibular first molar teeth were prepared with Class-II (proximo-occlusal) cavities and restored with a radio-opaque composite (Tetric N-Ceram). Two sets of standardized radiographs were taken from the 30 teeth, keeping the radiological parameters constant. One set of these 30 radiographs was named as SET 1. Ten randomly chosen radiographs from the other set and two other radiographs of Class-II composite restorations in typodont teeth constituted SET 2. Thirty dentally trained examiners were asked to match the 12 radiographic images of SET 2 with those of SET 1.Results:The results show that 15 examiners were able to correctly match all the 12 images. Statistical analysis was done using kappa statistical test.Conclusion:This study shows that, if the post-mortem radiographs are accurate duplicates of ante-mortem radiographs of composite restorations, then the shape of the composite restoration is unique and can be used for identification.
