Getting clear on clearance
Most of us do it in one way or another and at one time or another. We try to pass the buck. We think we do it for a good…
Load system of segmental T-loops for canine retraction
Introduction The orthodontic load system, especially ideal moment-to-force ratios, is the commonly used design parameter of segmental T-loops for canine retraction. However, the load system, including moment-to-force ratios, can be…
Etiquette in scientific publishing
Publishing a scientific article in a journal with a high impact factor and a good reputation is considered prestigious among one’s peer group and an essential achievement for career progression….
Influence on smile attractiveness of the smile arc in conjunction with gingival display
Introduction Many variables affecting smile esthetics and attractiveness have been evaluated. However, the influence of the interaction of several variables is not as well known. Furthermore, patients and dental professionals…
Impact of bisphosphonate drug burden in alveolar bone during orthodontic tooth movement in a rat model: A pilot study
Introduction The aim of this pilot study was to investigate the effect of long-term bisphosphonate drug use (bone burden) on orthodontic tooth movement in a rat model. Methods Sprague Dawley…
Effect of parathyroid hormone on experimental tooth movement in rats
Introduction The aim of this study was to investigate the effect of parathyroid hormone injection on experimental tooth movement in rats. Methods Sixty male Wistar rats were randomly divided into…
Pulp vitality and histologic changes in human dental pulp after the application of moderate and severe intrusive orthodontic forces
Introduction Orthodontic forces produce a series of changes in dental pulp. However, no one has attempted to investigate the incidence of pulp necrosis after orthodontic therapy in the clinic. In…
Assessment of the effect of combined multimedia and verbal information vs verbal information alone on anxiety levels before bond-up in adolescent orthodontic patients: A single-center randomized controlled trial
Introduction Despite the high prevalence of dental anxiety in children, there is little research examining anxiety before orthodontic procedures. This parallel-group randomized controlled trial assessed whether provision of additional multimedia…
Three-dimensional cone-beam computed tomography-based virtual treatment planning and fabrication of a surgical splint for asymmetric patients: Surgery first approach
Virtual 3-dimensional planning in orthognathic surgery allows for a detailed visualization and analysis of skeletal and dental deformities, especially in patients with asymmetries. This approach also eliminates conventional stone model…

Authors’ response
We want to thank Robert Vitral, Marcio Campos, and Marcelo Fraga for their interest and feedback regarding our research. They analyzed our 2 null hypotheses and stated that 1 was…
The null hypothesis
The null hypothesis is the proposition that implies no effect or no relationship between phenomena. It is a hypothesis that the researcher tries to disprove, reject, or nullify, whereas the…

Vincent G. Kokich, Editor-in-Chief of the AJO-DO , died on July 24, 2013, at his home in Gig Harbor, Washington. His death was sudden and unexpected, and a great loss…
Evaluation of buccal bone coverage in the anterior region by cone-beam computed tomography
Introduction The purpose of this study was to compare the sensitivity of diagnoses of buccal bone coverage in anterior teeth between axial and sagittal reconstructions using cone-beam computed tomography. Methods…
Reproducibility of bracket positioning in the indirect bonding technique
Introduction Current studies have compared indirect bonding with direct placement of orthodontic brackets; many of these have shown that indirect bonding is generally a more accurate technique. However, the reproducibility…
In memory of Vincent G. Kokich Editor-in-Chief, 2011-2013
When many words have already been written to describe the life of Vincent George Kokich (September 17, 1944-July 24, 2013), it seems unfair to rely upon one person to summarize…
