Reduced Radiation Exposure

You know that using rectangular collimation is the right thing to do, but did you know it reduces patient radiation exposure by up to 70%? Read more about rectangular collimation and the radiation reduction benefits it enables.

Tru-Image™ Articles and Research

Below you will find a wealth of research on the Tru-Align™, the previous generation of Tru-Image, including links to and summaries of research papers, white papers and peer-reviewed articles on all aspects of Dental Radiology, including research from the National Academy of Science, the American Dental Association and the FDA. There are also studies on rectangular collimation and the Tru-Align™ aiming device.

Creating a Safe, Effective X-ray Practice

Dale A. Miles, BA, DDS, MS, FRCD(C)

Information on how you can lower the risks of x-ray exposure to your patients. This article appeared in the April 2015 issue of DentalTown Magazine.

New Dental X-Ray Guidelines: How They Will Affect Your Practice

Dale A. Miles, BA, DDS, MS, FRCD(C)

An article on new dental x-ray guidelines posted on Henry Schein's Sidekick.

Radiation Minimization – “Are We There Yet?”

Dale A. Miles, BA, DDS, MS, FRCD(C)

If you've been on a long trip with kids you've probably heard the question many times - Are we there yet? It's easy to answer if you are driving the family car, not so easy in the dental practice when the patient asks you "Why do I need these X-rays?" or "Are these X-rays safe?" Hopefully this brief discussion of current concepts and guidelines, updated recently, jointly by the AAOMR and ADA, will give you the information necessary to take the final steps to minimize all of your patients' X-ray burden successfully and easily as well as answer their questions.

A comparison between bitewing radiographs taken with rectangular and circular collimators in UK military dental practices: a retrospective study

LA Parrott and SY Ng, Dentomaxilofacial Radiology (2011) 40, 102-109, British Institute of Radiology

This study provides evidence that rectangular collimation did not significantly affect the diagnostic yield of bitewing radiographs despite the presence of cone cut. Therefore, all practitioners should adopt rectangular collimation.

The ALARA principle: Do you know what it is?

Hoos, J. C. & Razzano M. V., Dental Economics

This report discusses how using rectangular collimation and faster speed film helps dental practices adhere to the ALARA (As Low As Reasonably Achievable) principle. The use of digital dental X-ray is noted to be another way to further reduce patient/staff exposure.

Evaluation of Radiation Exposure With the Tru-Align Intraoral Rectangular Collimation System Using OSL Dosimeters

Colosi, D.C., et al.

This study compares dental radiation exposure levels both to the patient (skin entrance and exit dose measurements) and the dental image sensor. Comparisons were made between a cylindrical collimator and the Tru-Align rectangular collimator. Among other findings, the study reported the rectangular collimator system reduces radiation exposure at the periphery of the outline of the cylindrical collimator by approximately 98%.

Implications of Implementing the ALARA Principle and NCRP Guidelines: How They Affect Your X-ray Procedures

Wright, D. N., Inside Dentistry, Jan/Feb. Vol. 2, Iss. 1

The article lists six different ways a dental practice can comply with the National Council on Radiation Protection and Measurements guidelines for radiation protection, following the ALARA Principle. The author concludes that the easiest and most beneficial place to start would be by replacing circular cones with rectangular cones, a very effective way to reduce radiation exposure of patients and staff, and it also helps to produce more readable X-rays.

Dental X-rays and the Risk of Thyroid Cancer: A Case-Control Study

Memon, Godward, Williams, Siddique & Al-Saleh, Acta Oncologica, Jan/Feb. Vol. 2, Iss. 1

This article discusses the largest case-control study on the subject of dental radiography and its possible association with thyroid cancer as a source of multiple low dose radiation to the gland.

Health Risks from Exposure to Low Levels of Ionizing Radiation

Beir VII, Report in Brief, June 2005

Although the general consensus of dental radiologists is the dosage from dental x-ray exposure is not harmful; the absence of conclusive proof that establishes the absence of risk means it must be assumed there is potential of some risk from diagnostic exposure. This article outlines application of the ALARA (As Low As Reasonably Achievable) principle. The same safety procedures that minimize exposure for both patient and operator can also increase the quality of the radiographic images.

Importance of Optimizing Collimation to Reduce Unnecessary Dose

Farman, A. G.

Letter discussing the benefits of using rectangular collimation as a means of reducing dental radiation dose and the chances of fatal cancer from dental radiography by at least 60%. Also, why the belief that use of digital solid state detectors alone results in substantial dental patient dose reduction is a misconception. Dr. Farman also outlines the specific benefits of Tru-Align for radiograph image quality, patients and dental practices utilizing the device.

NCRP Report No. 145: New Dental X-ray Guidelines: Their Potential Impact on Your Dental Practice

Dale A. Miles DDS, MS, and Robert P. Langlais DDS, MS, Dentistry Today, Sept 2004

“The purpose of this article is to summarize the newest dental x-ray guidelines from the National Council on Radiation
Protection and Measurements (NCRP) report No. 145, which was released in December 2003, and alert dentists to the
potential impact on their office radiographic procedures”
