INTRODUCTION This in vitro study compared the apical sealing ability of three common root end filling materials namely mineral trioxide aggregate (MTA), intermediate restorative material (IRM) and calcium-enriched mixture (CEM) cement using a bacterial leakage model. METHODS AND MATERIALS The study was conducted on 83 single-rooted human teeth. Tooth crowns were cut and root canals were prepa...

THE INTERNATIONAL JOURNAL OF ESTHETIC DENTISTRY Nowadays, clinicians have access to a great variety of restorative materials. As there is restricted access to test materials in private practice, most clinicians make their selection of esthetic biomaterials on the basis of scientific articles,1 lectures, company recommendations, and through the sharing of information and experience among colleag...

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 wide use of chairside CAD/CAM restorations has increased the diversity of the restorative material. For the practitioner, the selection of the appropriate material is difficult amongst the variety offered by the market. Information on the characteristics of the products can be difficult to assess due to the lack of up-to-date classification and the lack of reliability of manufacturer's adve...

In the K-12 curriculum, mathematics plays a significant role and is given specific attention. To keep up with pace, teachers need have set of teaching options, including not simply chalk talk but also other methods tactics for gaining students' attention imparting knowledge. Reducing learning competencies by 60 prescribed module may be sufficient to learners achieve variety objectives ideas or ...

The aim of this study was to histopathologically examine the biocompatibility of the high-copper amalgam, intermediate restorative material (IRM), mineral trioxide aggregate (MTA), and MTA mixed with chlorhexidine (CHX). This study was conducted to observe the rat subcutaneous connective tissue reaction to the implanted tubes filled with amalgam, IRM, MTA, and MTA mixed with CHX. The animals we...

As dentistry continues to evolve, new technologies and materials are continually being offered to the dental profession. Throughout the years restorative trends and techniques have come and gone. Some material developments have transformed the face of esthetic dentistry, while other initial concepts have already phased out and disappeared. Today, all-ceramic restorations continue to grow in the...

Dental material research has improved the application and performance of the polymer-based restorative dental composite materials. In spite of these advances, some deficiencies exist in their

Restorative dentistry plays an important role in the field of dentistry in restoring the tooth tissue to its form, function esthetics and in maintaining the physiologic integrity in harmony with the surrounding hard and soft tissues. Many of the restorative material used did not adhere to enamel to dentin by physical and / or clinical interactions thus increasing the chances of microleakage at ...
