An aiming device for an extraoral radiographic technique

Area of Science:

• Dentistry
• Radiology
• Medical Devices

Background:

• Intraoral radiography can be challenging for patients undergoing endodontic therapy.
• Extraoral film placement offers an alternative technique for dental imaging.
• A need exists for improved methods to guide film/sensor and X-ray beam alignment in extraoral radiography.

Purpose of the Study:

• To devise and evaluate a novel aiming device for periapical radiography using the extraoral technique.
• To assess the efficacy of the device in obtaining diagnostic-quality images for endodontic assessment.

Main Methods:

• An aiming device was assembled using locator rings, indicator rods, a bite block, and a rubber tube.
• The device was used to capture periapical radiographs on 12 adult volunteers utilizing the extraoral technique.
• Specific X-ray cone angulations relative to the horizontal plane were employed for upper and lower molars.

Main Results:

• The newly devised aiming device facilitated the successful acquisition of appropriate periapical radiographs.
• Diagnostic-quality images of the upper and lower molar regions were obtained in all 12 participants.
• The technique proved effective for both left upper and right lower molar areas.

Conclusions:

• The developed aiming device is effective for performing extraoral periapical radiography.
• This innovation provides a practical solution for obtaining dental radiographs in patients intolerant to intraoral sensors.
• The device simplifies the process, ensuring appropriate image acquisition in endodontic procedures.
