Joanie and Jimmy Read are 12-year-old twins for whom you have just initiated treatment to resolve severe crowding. This is a “salt of the earth” family. The twins’ parents are…
Ethics in orthodontics
I read the Ethics article in the August issue with much interest (Greco PM. What values most? Am J Orthod Dentofacial Orthop 2014;146:139). I recall being a first-year resident, interviewing…
Waiting for the litmus test?
When I read the title of the August editorial, “Pitching speed,” I grew curious and swiftly got into action reading the content. To be honest, from the outset, I was…
Authors’ response
First, we want to thank Dr Daniel A. Kuncio for his interest in our article. Regarding all the other forces and moments, Dr Kuncio wondered where they did come from. We…
It is all about definitions
I carefully read the article “Forces and moments generated by removable thermoplastic aligners: Incisor torque, premolar derotation, and molar distalization” (Simon M, Keilig L, Schwarze J, Jung BA, Bourauel C….
Analysis of data in removable thermoplastic aligner study

We thank Drs Kailasam, Jagdish, and Chitharanjan for taking a keen interest in our article, “Comparative assessment of alignment efficiency and space closure of active and passive self-ligating vs conventional…
Self-ligation and faster treatment time—a myth?
We read with great interest the article in the May issue entitled “Comparative assessment of alignment efficiency and space closure of active and passive self-ligating vs conventional appliances in adolescents:…
Three-dimensional cephalometric superimposition of the nasomaxillary complex
Introduction Two-dimensional maxillary superimposition techniques have been routinely used in clinical practice, but a 3-dimensional plane has yet to be introduced and validated. The purposes of this study were to…
Adverse responses to products or treatments
Orthodontists are blessed in many ways. One of our blessings involves the safety and high quality of the products that are now available for our use. Another is the relative…
Interpretation of observational studies
Ideally, the objective of a clinical trial is to determine with a high degree of certainty whether the intervention of interest is truly effective. In high-quality randomized trials, if the…
Dimensions of central incisors, canines, and first molars in subjects with Down syndrome measured on cone-beam computed tomographs
Introduction The literature on tooth dimensions in subjects with Down syndrome (DS) is scarce. To our knowledge, no studies have yet been published in which the morphometry of the teeth…
Surgically assisted rapid maxillary expansion: Cone-beam computed tomography evaluation of different surgical techniques and their effects on the maxillary dentoskeletal complex
Introduction The aims of this study were to evaluate and compare skeletal, dentoalveolar, dental, and periodontal changes in surgically assisted rapid maxillary expansion (SARME) patients with and without pterygomaxillary disjunction….
Three-dimensional monitoring of root movement during orthodontic treatment
Introduction A significant objective of orthodontic treatment is to achieve proper and stable tooth positions that involve not only the crowns, but also their roots. However, the current methods of…
