Discuss or comment on this article.
Conclusions: Biofilm disruption and cell viability were influenced by the species, their coassociation in dual-species biofilms, the test agent, and the duration of exposure. The effectiveness of NaOCl as an endodontic irrigant was reinforced.

Conclusions: The Root ZX and the Mini Apex Locator devices increased significantly the precision to determine the real working length after the preflaring procedure. All the EALs showed an acceptable determination of the working length between the ranges of±0.5mm except for the Apex DSP device, which had the lowest accuracy.

Discuss or comment on this article.
Abstract: A light and electron microscope examination of the resected root tip of a failing endodontically re-treated lower molar was examined. The tooth had been initially treated 10 years ago and then re-treated 2 years ago. The resected root tip was sectioned axially, and thin sections were examined through the entire length of the specimen. Thin sections were examined with a transmission electron microscope. The thin sections were randomly chosen along the isthmus areas between the mesiobuccal and mesiolingual canals. Our findings suggest that a complex, variable, multispecies biofilm was present the entire length of the specimen.

My e-mails dropped to a new low over the summer weekend I reserved to write this editorial, but that only made it more difficult to concentrate on the topic of interest—the use of removable aligners. The weather seemed almost too good to miss, and, without a steady stream of e-mails tethering me to my computer, I was tempted to slack off a bit. The unpredictability of e-mail today reminds me of the flow of new examinations when I was first in practice: it always seemed there were either too many or too few. But after 38 years of fretting over those numbers, I concluded that it was better to have too many than too few.

This article reports experimental findings that suggest that orthodontic appliances do not negatively impact esthetic judgments. Although the authors are to be applauded for several aspects of their study, not the least for the photorealistic manipulation of their stimuli, there are a number of potential methodologic flaws and limitations to which I want to draw attention.

It was a pleasure to receive the letter from Dr Robert Burriss. We thank him for his comments about our study (Berto PM, Lima CS, Lenza MA, Faber J. Esthetic effect of orthodontic appliances on a smiling face with and without a missing maxillary first premolar. Am J Orthod Dentofacial Orthop 2009;135[Suppl 1]:S55-60) and for his interest in it. His letter raises a few questions, and this is an invaluable opportunity to clarify some points about our study methods.

Five observers plotted 24 landmarks using computer displays of multi-planer reconstruction (MPR) CBCT and Ceph views during separate sessions.

Conclusions: In the alveoloar process, 1 mm or more cortical bone thickness can be expected in the posterior dentition area.

The midpalatal area and the retromolar pad area are also excellent locations for microimplant placement. Because of limited interradicular spaces, the recommended diam...

Conclusions: The combination of accelerated osteogenic orthodontics and a partially osteointegrated mini-implant (C-Implant) was a safe and effective treatment choice. The C-implant's surface allows partial osseointegration, so it can resist a force moment without loosening and withstand the heavy forces associated with the accelerated osteogenic orthodontics protocol.

Ankylosis of a tooth is a pathologic condition commonly manifested by infraocclusion and vertical alveolar bone defect of the involved tooth. Extraction is often indicated in patients with severe tipping of adjacent teeth and serious infraocclusion, rather than attempting orthodontic repositioning. However, the residual alveolar bone defect after extraction must be restored adequately to establish sound dentition with a healthy periodontium. The bone-forming potential of sound periodontal ligament cells of the adjacent teeth can be used to restore the bone defect, through precisely controlled mesial movement of the root of...

We report here the case of a woman with Class III malocclusion and advanced periodontal disease who was treated with surgical orthodontic correction. Functional recovery after orthodontic treatment is often monitored by serial electromyography of the masticatory muscles, whereas 3-dimensional cone-beam computed tomography can provide detailed structural information about, for example, periodontal bone defects. However, it is unclear whether the information obtained via these methods is sufficient to determine the treatment goal. It might be useful to address this issue for patients with advanced periodontal disease because...
