Context: Temporary anchorage devices (TADs) have been introduced to orthodontic treatment for enhancing anchorage control. It is claimed that they are not disposable and can be used several times after sterilization process. However, the question is whether this repeated sterilization has any effect on the properties of these devices. This study was done to review the available articles that had addressed various aspects of this issue.Evidence Acquisition: The authors searched several electronic data bases including PubMed, Google Scholar, Scopus and Embase with several key words related to orthodontic temporary anchorage devices and sterilization. The relevant articles were reviewed and categorized in the following subjects: mechanical properties, primary stability and clinical success, and histologic and microscopic characteristics. Results: Sterilizing the temporary anchorage devices seems not to affect the mechanical properties of these devices.
Conclusions: In terms of primary stability, and clinical success, very few studies are available. Histologic and microscopic evaluations showed some alteration in the surface characteristics of TADs including some mineral precipitation.

Background: Facial trauma is a common sport-related injury and risk of this injury in contact sports is greater than non-contact sports. Facial trauma has been suggested as a possible etiologic factor of temporomandibular disorder (TMD).
Objectives: The purpose of this study was to investigate the frequency of TMD and its clinical manifestation in boxers of Islamic Republic of Iran national team. Materials and Methods: In this study, thirty-two male players with average age of 23.75 ± 2.21 who were playing boxing more than 6 years were evaluated regarding TMD. After taking the history, a clinical examination was performed for each athlete. The presence of at least a sign or symptom was considered as TMD diagnosis. Data were collected and presented as descriptive findings. Results: Of 32 boxers, 28.1% (9 cases) had TMD and 71.9% (23 cases) were healthy. The most common symptom was ante-auricular pain (25%) followed by neck pain (21.87%) right ante-auricular tenderness (9.37%) muscle tenderness (9.37%), neck tenderness (9.37%) and headache (3.12%). The uppermost sign was right joint click (25%) followed by left joint click (12.5%) and jaw deviation during mouth opening (12.5%).average age of (25 ± 2 years) and boxing record (10.44 ± 2.29 years) of athletes with TMD were higher than average age of (23.26 ± 2.4 years) and boxing record (7.26 ± 1.76 years) of athletes without TMD.
Conclusions: This study showed that the prevalence of various sign and symptoms of TMD is relatively high in boxers which could result from boxing-related facial trauma.

One of the most important characteristic of dentition is dental arch form. In orthodontic treatment, it is crucial to understand each individual dental arch for diagnosis and treatment planning and try to preserve it throughout the treatment to achieve a higher stability. Additionally, it is important to maintain a wellestablished coordination between maxillary and mandibular dental arch to have a perfect functional occlusion. In orthodontics up to now, different definitions have been proposed for human dental arch form and methods for coordinating dental arches. The aim of this study was to gather and compare these concepts. The available data were categorized and discussed in five different domains: Arch Form (history and recent concepts), Factors affecting dental arch form, Characterization of arch form, Coordination of upper and lower arches and arch wire selection and arch form.
