Mandibular rotation revisited: What makes it so important?
Orthodontists have long been aware that mandibular rotation takes place during growth, but most have underestimated its importance. This is so because the distinction between the true rotation and the rotation of the mandibular plane is typically not made. Traditionally, orthodontists have focused on the mandibular plane, which changes little because modeling on the lower mandibular border largely hides the true rotation that occurs. Furthermore, orthodontists must understand that changes in tooth position—over which they have great control—play an important role in determining the true rotational changes that occur. (...

Nitric oxide in human gingival crevicular fluid after orthodontic force application
Reducing the duration of patient treatment is a primary goal for orthodontists.1 The development of new methods to increase the rate of orthodontic tooth movement (OTM) have been sought by clinicians not only as a way to shorten treatment time, but also to reduce adverse effects such as pain, discomfort, dental caries, and periodontal disease. Additionally, shorter treatment times can minimize iatrogenic tissue damage, such as root resorption and the development of non-vital teeth.2 (Source: Archives of Oral Biology)

Class II treatment with functional appliances: A meta-analysis of short-term treatment effects
The efficacy of functional appliances and changes produced by their application are still the subject of controversy. Functional appliances encompass a range of removable and fixed devices that are designed to create three-dimensional changes in the dentition and development of the jaws. This meta-analysis aims to analyze current literature up to January 2013 to provide evidence regarding the effects of functional appliances (removable FA and fixed FA). A literature survey of articles was initiated with meta-analysis using the random effect model (REM) along with heterogenesis and sensitivity analyses. (Source: Seminars in Orthodontics)

Class II malocclusion and sleep-disordered breathing
Sleep-disordered breathing (SDB) is gradually being recognized today as having significant health implications for individuals who are suffering from this condition and especially those who remain undiagnosed and may not be receiving the necessary treatment. Today, more attention is being directed to identifying potential risk factors that contribute to individuals developing this condition. Moreover, it has been established that certain craniofacial morphological characteristics have been associated with SDB. (Source: Seminars in Orthodontics)

Cephalometric and Dental Analysis of Class II, Division 2 Reveals Various Sub-types of the Malocclusion and the Primacy of Dentoalveolar Components
Class II, Division 2 malocclusion defies the original definition by Angle, both as phenotype and in etiology. Many subtypes have been described, including “Class I, Division 2", mostly on the basis of occlusion and cephalometric measurements. In this paper, we explore a stratification of 4 cephalometric patterns of Class II, Division 2, based on the inclination of maxillary incisors and vertical divergence. While strong genetic components have been recognized, the influence of environmental factors is emphasized through a hypothesis to be tested. (Source: Seminars in Orthodontics)

Component Analysis of Class II, Division 1 Discloses Limitations for Transfer to Class I Phenotype
Any malocclusion, most particularly Class II, must be diagnosed and treated on the basis of its many components, and not simplified to one or only several spatial relationships. Research points out the inability of common approaches of treatment to transform a Class II, Division 1 phenotype to a facial pattern with normal skeletal relationships that would be expected with a Class I phenotype. These observations underscore the structural differences between the various classes of malocclusion in addition to the definition of treatment outcome as the cumulative effect of small to moderate changes in the various skeletal and ...

Let’s pretend
Judged at least by the rubrics under which they are listed, there are many ways of treating a Class II malocclusion—dental “camouflage,” “growth modification,” maxillary orthopedics, and so forth. Each method commonly is assumed to achieve a unique, superior, most appropriate type of correction. It will be the purpose of this minority opinion to argue that all treatments ultimately traverse the same path, utilize the same mechanism, and to a first approximation, achieve the same result. The choice of methods, therefore, is a practice management decision. (Source: Seminars in Orthodontics)

Chlorhexidine gel and less difficult surgeries might reduce post‐operative pain, controlling for dry socket, infection and analgesic consumption: a split‐mouth controlled randomised clinical trial
Summary Reports on post‐surgical pain are a few, controversial and flawed (by statistics and analgesic consumption). Besides, it is not known if chlorhexidine can reduce post‐extraction pain adjusting for its effect on prevention of infection and dry socket (DS). We assessed these. A total of 90 impacted mandibular third molars of 45 patients were extracted. Intra‐alveolar 0·2% chlorhexidine gel was applied in a split‐mouth randomised design to one‐half of the sockets. None of the included patients took antibiotics or analgesics afterwards. In the first and third post‐operative days, DS formation and pain leve...

Natural History of Periodontitis
Abstract Prospective studies have been conducted around the world to investigate the natural progression of periodontitis. Eight populations, with at least five years of observation, have been investigated in Norway, Sri Lanka, China, Indonesia, Australia, Germany, New Zealand, and Brazil. The findings from each population were based on the assessments of clinical periodontal parameters, microbiological samplings, socioeconomic status, tobacco use, and daily oral hygiene. Periodontitis was not commonly seen in the younger cohorts. With increasing age, however, the prevalence and severity of periodontitis rose sign...

Soft tissue airway dimensions and craniocervical posture in subjects with different growth patterns.
Conclusions: Smaller nasopharyngeal and oropharyngeal airways were seen in connection with a large craniocervical and a large mandibular inclination. We therefore suggest that the vertical skeletal pattern may be one of the factors that contribute to nasopharyngeal and oropharyngeal obstruction.

Mechanical weakening of devitalized teeth: three dimensional Finite Element Analysis and prediction of tooth fracture
ConclusionThe combined Finite Element Method and the Maximum Principal Stress analysis gave insight into the fracture mechanisms of teeth with two‐surface composite restorations followed by root canal preparation. Removal of tooth tissue, despite its subsequent restoration with dental materials, weakened the tooth by changing the stress intensity and distribution through tooth structures. Access cavity preparation had the greatest influence on tooth strength while canal enlargement did not contribute to this process substantially.This article is protected by copyright.
