Radiovisiography versus conventional radiography for detection of small instruments in endodontic length...

Area of Science:

• Dentistry
• Radiology
• Endodontics

Background:

• Intraoral radiography is crucial for endodontic diagnosis.
• Radiovisiography (RVG) offers a digital alternative to conventional dental films.
• Assessing RVG's diagnostic accuracy compared to traditional methods is important.

Purpose of the Study:

• To compare the diagnostic clarity of radiovisiography with conventional radiographs for endodontic file visualization.
• To evaluate different image processing modes of RVG and conventional film speeds (D-speed and E-speed).

Main Methods:

• Twenty-five extracted maxillary molars were radiographed using RVG and conventional D-speed/E-speed films.
• Images were assessed for the clarity of size 8 and 10 endodontic file tips relative to the radiographic apex.
• RVG images were processed in original, enhanced, negative-to-positive, standard zoom, and zoom negative-to-positive modes.

Main Results:

• Zoom in negative-to-positive mode RVG was statistically equivalent to D-speed radiographs (p=0.264) and superior to E-speed (p<0.001).
• Standard zoom RVG was also superior to E-speed radiographs (p=0.025).
• D-speed radiographs were judged superior to E-speed radiographs 90% of the time.

Conclusions:

• Radiovisiography, particularly with enhanced processing (zoom negative-to-positive), provides diagnostic clarity comparable to D-speed films.
• Both RVG and conventional radiographs with magnification allow accurate identification of endodontic file tips.
• Digital radiography systems like RVG show promise for improving endodontic imaging.
