- What really countsby Peter M. Greco on 01/04/2021 at 12:00 am
You remember Sean quite well. He was the salutatorian of your dental school class. Although many of your classmates did not match or were not accepted to specialty programs immediately after dental school graduation, Sean was promptly invited to his first-choice program. He was an intelligent fellow, almost charismatic in demeanor with an apparent warmth that seemed as if it could charm a snake. But his reputation for cheating on exams was legendary among those in your class. This behavior was just 1 example of his predisposition toward dishonesty and deception.
- Normality test: Is it really necessary?by Michail Tsagris, Nikolaos Pandis on 01/04/2021 at 12:00 am
Statistical tests used to analyze data require assumptions for the results to be valid. For instance, when performing an independent t test for the equality of 2 means, the normality assumption mandates that the populations from which the 2 samples were drawn follow the normal distribution. In linear regression analysis, a basic assumption is that the residuals are normally distributed.
- Authors' responseby Dalia El-Bokle, Noha Hussein Abbas on 01/04/2021 at 12:00 am
We thank the authors for their letter and interest in our article. They questioned whether leveling the curve of Spee would be compromised because of using bonded inclined bite raisers on premolars in patients with Class II malocclusion with a deep overbite because of an intrusive force vector on the premolars.

- Posterior arch defectsby Gerald W. Spencer on 01/04/2021 at 12:00 am
Hearty congratulations to the authors for their publication on posterior arch defects (Selvam NP, Hansen M, Kashtwari D. Incidental findings of posterior arch defects of the atlas in orthodontic patients: a case series. Am J Orthod Dentofacial Orthop 2020;158:35-9). It was noteworthy that they recognized that the orthodontist might be the first to see, recognize, and report such findings, being the first to take cephalometric films to identify such anomalies. Highlighting the clinical significance of these entities, the authors' stated primary goal was well done, as well as pointing out how “the diagnosis of these defects could lead to a major lifestyle change.” That is a correct assessment.

- Deliberationsby Laurance Jerrold on 01/04/2021 at 12:00 am
In Lipinski v Krupp, No. A-02561-5T3 (NJ Super Ct App Div, Feb 15, 2017), the plaintiff, on behalf of the deceased patient, submitted the following motion in his appeal, having lost at the trial court level. He claimed that “[T]he combined timing, language, and circumstances surrounding the issuance of the trial court's supplemental deliberations charge coerced the jury into reaching an expeditious verdict that manifested a surrender by one or more of the jurors’ convictions and caused a miscarriage of justice.” For the reasons stated below, the appellate court disagreed and affirmed the lower court ruling in favor of the defendant.

Orthodontically induced inflammatory root resorption (OIIRR) constitutes an undesirable risk connected to orthodontic treatment. Finite element analysis (FEA) is a powerful tool to study the risk of OIIRR. However, its efficiency in predicting OIIRR depends on the insertion of the correct inputs and the selection of an output coherent with the clinical failure mechanism.

- Roles of autophagy in orthodontic tooth movementby Yina Li, Laura Anne Jacox, Shannon Coats, Jane Kwon, Peng Xue, Na Tang, Zou Rui, Xiaoyu Wang, Yong-Il Kim, Te Ju Wu, Yan-Ting Lee, Sing Wai Wong, Chia Hui Chien, Chih-Wen Cheng, Ryan Gross, Feng-Chang Lin, Henry Tseng, Jennifer Martinez, Ching-Chang Ko on 23/03/2021 at 12:00 am
Orthodontic tooth movement (OTM) relies on efficient remodeling of alveolar bone. While a well-controlled inflammatory response is essential during OTM, the mechanism regulating inflammation is unknown. Autophagy, a conserved catabolic pathway, has been shown to protect cells from excess inflammation in disease states. We hypothesize that autophagy plays a role in regulating inflammation during OTM.
- For four sixes, revisitedby Andrew DiBiase, Cara Sandler, Paul Jonathan Sandler on 23/03/2021 at 12:00 am
Rarely is the extraction of the four first molars the ideal choice in the course of orthodontic treatment, particularly in older patients. Although this approach can offer distinct advantages in carefully selected patients, it is also associated with a number of well-recognized problems, including the extension of treatment times, anchorage management, and control of second molars during space closure. However, by careful use of contemporary materials and techniques, a high standard of treatment can be achieved, even in patients with complex malocclusions.
