THE EDITOR'S CORNER

50 Weeks to Our 50th

DAVID S. VOGELS

Like almost every U.S. orthodontist, JCO maintains a Facebook page as one means of connecting with its customer base—in your case, patients; in ours, readers. The format doesn’t necessarily lend itself to dispensing clinical information, although we have recently begun posting helpful videos related to our published Pearls. We tend to get the most likes and shares from our monthly profiles of finalists for the Eugene L. Gottlieb JCO Student of the Year Award (the most recent winner was announced in the March 2017 issue), no doubt because of these students’ extended networks of relatives and colleagues. But the 50th-anniversary year of the journal has brought us an opportunity for a new and unique Facebook venture.

THE CUTTING EDGE

Effects of Photodynamic Therapy on the Clinical and Biomechanical Efficiency of Mini-Implants: A Randomized Controlled Trial

RAJ KUMAR MAURYA MDS, ANKUR GUPTA MDS, HARPREET SINGH MDS, SURBHI THAKKAR MDS, HARSH ASHOK MISHRA MDS

Photobiomodulation (PBM) and photobiomodulation therapy (PBMT) are two terms we are hearing more about in our profession and other areas of health care. We see various devices, some over-the-counter, using PBMT to treat acne, wrinkles, hair loss, and pain. PBMT is also being applied for smoking cessation, weight loss, addiction therapy, nerve regeneration, and more. Current research is investigating its use to mitigate the effects of Alzheimer’s and Parkinson’s diseases. It seems almost too good to be true, but studies on the effects of light in the red-to-infrared range (600-1,070nm) have validated PBMT’s effects on a cellular level.

Miniscrew-Supported Orthodontic Pseudo-Ankylosis for Mesialization of a Lower Third Molar

NICOLA DERTON DMD, DANIELA LUPINI DMD, MAURO COZZANI DMD, MScD

Adult orthodontic treatment sometimes requires lower third-molar uprighting and mesialization. In the past, to avoid unwanted reciprocal movement of the anchorage unit, absolute anchorage could be obt...

Measuring Bonded Lingual Retainers

NEAL D. KRAVITZ DMD, MS, JEFFREY M. SHIRCK DDS, MS

Multistranded lingual retainers are commonly “eyeball” measured for length during bonding, which can result in a retainer that is too long or too short. The time needed to cut a new retainer wire exte...
