Throughout 2015, we are celebrating 100 years of Journal publishing. In the May issue, look for two editorials entitled "Who is an orthodontist?" The first was written by the Journal's first editor, Martin Dewey, and was originally published in 1915. In his Reprise for 2015, the Journal's current Editor-in-Chief, Rolf G. Behrents, examines how things have changed in the last 100 years.

Dental Curing Light: Benefits and Hazards of Blue Light

In dentistry and orthodontics in particular, the dentist and staff are acutely exposed to blue light, via the LED Curing Light. We don't stare at the sun, but we do spend a lot of time staring
at a composite curing light whether restoring a tooth, or placing an orthodontic bracket.

Historically, bands were cemented on the teeth or a two part chemical care system was used to place orthodontic brackets. Currently most orthodontists are using the light cure system to place brackets. Most of the orthodontic residency programs are using the LED curing light because of the increased flexibility, accuracy, working time, and reduced bonding (curing) time. The new curing lights are more powerful and rechargeable with three- to twenty-second cures.

Blue light is short wavelength visible blue light and generates the highest energy of the spectrum. When this high energy visible blue light (HEV) 400-500nm hits the retina, it mixes with oxygen to create a destructive force 3 that destroys photoreceptors and retinal pigment epithelial cells. Over time, this process can lead to Age Related Macular Degeneration.

Blue light not only emits electromagnetic radiation, but is also responsible for controlling your circadian rhythm; ie, your sleep cycle via suppression of melatonin production. Melatonin has a potent anti-inflammatory and anti-carcinogenic benefit. When you are exposed to the blue wavelength of light, your brain receives the signal that it is daytime, and responds by suppressing melatonin.

We are exposed to more blue light today than ever before. Outdoors, the sky is blue (from blue light), and indoors we face multiple blue light hazards from television screen, computer screens, I-pad screens, smart phone screens, and LED dental curing lights. We light our homes and offices with energy efficient CFL and fluorescent bulbs that have a high blue spectral emission.

It is estimated that 1.8 million Americans suffer from Age Related Macular Degeneration. This is the number one cause of blindness in America. These numbers are expected to double in the next few decades.2 "Our society could be facing an unprecedented public health crisis in the form of vision loss if the magnitude of blue light exposure continues unchecked."3

We as practitioners and consumers are conducting a natural experiment on ourselves
and we must wear protective equipment to reduce ocular injury.

The JADA recommends that we use protective (orange) glasses and/or shields that meet the
ANSI Z87.1-2003 standard. The glasses filter out 98% of the blue light frequencies. We should not stare directly at the light.

As of now, no one has the conclusive answers and more research needs to be done. Be proactive and use protective gear for your own personal safety and the safety of your staff while
using the curing blue light for all of its benefits.

2015 Supplement and Product Guide
Each year, in April, the AJO-DO publishes special Supplement, highlighting the products and services that many companies provide to orthodontists. The Supplement is available online and in print.

The Supplement also includes a selection of editorial and scientific content. The lead article in this year's Supplement is a review of bonding, by Paul Gange, President, Reliance Orthodontic Products, Inc, Itasca, Ill.

Peer Review
The AJO-DO uses a blind review process; the identity of the author and the location of the research are concealed from the reviewers, and vice versa.  
In the past, AJO-DO staff has often blinded new submissions when authors fail to do so. But, with nearly 1,000 articles submitted last year, and the submission rate still growing, staff (aka, me!) can no longer do this. Submissions that are not blinded for peer review will be returned to the author for revision prior to review. This is an unnecessary delay.
The following submission items are sent to reviewers during the review process and therefore should not reveal any identifying information.
* Manuscript * Figures * Tables * Other Material *
The Title Page is not sent to reviewers, and it should contain complete author information, including each author's contribution to the submission. 
In the Manuscript, please pay special attention to Materials and Methods and Acknowledgments; wherever an author or location is mentioned, use the “hidden” format in Word to conceal it, or remove it to the Title Page.
For more  information, see the AJO-DO Author Information.

Daniel J. Subtelney
When Dr Subtelney was asked to write a guest editorial in July 2014 for the 100th Anniversary Celebration of the AJO-DO, he enthusiastically agreed to do so, and he completed the task shortly thereafter. He died on September 17, 2014, and this guest editorial represents his final lesson for the specialty that he loved so dearly.

Appropriate use of ionizing radiation in orthodontic practice and research

Ionizing radiation has revolutionized orthodontic practice and research in the past century.  One of the latest advances in imaging is cone-beam computed tomography. CBCT images have more information than conventional images but expose patients to more radiation. Every practitioner needs to to carefully weigh the costs and benefits exposing a patient to ionizing radiation. Key principles for radiographic imaging are justification, optimization, and dose limits.

The author of this article, Dr. Ahmad Abdelkarim, has dual specialty training in orthodontics and oral and maxillofacial radiology. He is also the editor of the AAO's new CBCT Resource Center, which is now available to AAO members at aaoinfo.org. The CBCT Resource Center is a compilation of information about the use of Cone-Beam Computed Tomography (CBCT) in orthodontic treatment. It is an initiative of the AAO Council on Scientific Affairs (COSA).

The evolution of journal communication

Wayne G. Watson, Editor Emeritus
Editor Emeritus of the AJO-DO Wayne G. Watson penned a Guest Editorial for the February edition. In it, he reviews the history of the journal through its 8 editors-in-chief.  Dr. Watson held the job himself, from 1978 - 1986.  Each editor steered the journal through changes in science, technology, and politics, and each left the journal strong and well-equipped to face whatever changes the future would bring.

Read this interesting Guest Editorial from a former Editor-in-Chief in the February issue.
