Summary
This study assessed the radiopacity of various root filling materials using digital radiography. All tested materials, including Resilon and AH Plus, exceeded the minimum radiopacity standards required for dental applications.
Area of Science:
- Endodontics
- Dental Materials Science
- Radiology
Background:
- Radiopacity is a critical property for root filling materials, enabling visualization on radiographs.
- Accurate assessment of radiopacity is essential for effective endodontic treatment monitoring.
Purpose of the Study:
- To evaluate and compare the radiopacity of commonly used root filling materials.
- To determine if these materials meet established radiopacity standards.
Main Methods:
- Digital radiography was employed to assess radiopacity.
- Materials including AH Plus, Endofill, EndoREZ, Epiphany, gutta-percha, and Resilon were tested.
- Radiopacity was quantified using an aluminum stepwedge and expressed in millimeters of aluminum equivalent.
Main Results:
- Resilon exhibited the highest radiopacity (13.0 mm Al eq.), followed by AH Plus (11.2 mm Al eq.) and gutta-percha (9.8 mm Al eq.).
- Epiphany (8.0 mm Al eq.), Endofill (6.9 mm Al eq.), and EndoREZ (6.6 mm Al eq.) showed lower radiopacity values.
- All tested materials surpassed the minimum ANSI/ADA Specification 57 requirement of 3 mm Al eq.
Conclusions:
- All evaluated root filling materials demonstrate sufficient radiopacity for clinical use.
- The findings provide valuable data for clinicians selecting materials based on their radiographic visibility.

01:24X-ray Imaging
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
01:30Radiological Investigation I: X-ray and CT
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and the...
