Fixed mandibular propulsion appliances are an alternative for the treatment of Class II malocclusion in individuals with mandibular deficiency. Since they are fixed appliances, said devices keep the mandible in an anterior-forced position during rest and during all mandibular functions. When a propulsive appliance is used, the lower jaw is displaced forward and downward. This movement leads to a new position of the condyle, which can, ultimately affect the normal functioning of the temporomandibular joint (TMJ). The aim of this paper was to review effects of fixed mandibular propulsive appliance on TMJ. Inclusion criteria considered studies on animals or humans using TMJ radiography, computed tomography, and magnetic resonance imaging. Studies confirm a favorable relation between condyle and glenoid fossa following treatment with fixed mandibular propulsion appliances.

Class II malocclusion features a high prevalence in Brazil, being considered as a routine in orthodontic clinics. A number of appliances are shown in the literature in order to correct Class II malocclusion with mandibular retrusion. Herbst´s fixed functional appliance, idealized by Emil Herbst (1905) and reintroduced, in the 1980´s, by Hans Pancherz is highlighted for maintaining the mandible continuously advanced, showing a shorter active treament time, an immediate esthetic impact on the facial profile, as well as requiring no patient´s commitment. Recent researches indicate the use of this appliance in individuals after pubertal growth surge. The aim of the present study is to show the orthodontics practitioner the option to use this appliance so as to treat Class II in individuals after the growth surge, obtaining satisfactory outcomes and further Class II correction.

Temporomandibular joint disorders causing limitation of mouth opening and pain may be related to the restriction of slipping or forward displacement of the mandibular condyle. Temporomandibluar arthrocentesis is the lavage of the joint and is regarded as a simple method that produces good results in patients with these symptoms. This article reports a case of disc displacement and closed lock in a patient who reported limited mouth opening and pain as the main symptoms. The treatment proposed was arthrocentesis and lavage, combining a corticosteroid with a sodium hyaluronate solution. It is concluded that arthrocentesis is a simple, efficient and barely invasive method for particular types of temporomandibular joint disorders and should be considered before opting for more invasive surgical procedures.

Respect for differences is one of the most important subjects in debate in the Brazilian and World society today. It’s consensus that diversity education is very important to make humanity fairer and more equal. In this context, it’s necessary to separate real pedagogic actions from political demagogy. So, our objective in this paper is to enrich this discussion with the results of our project “Perspectives of teachers about the inclusion of special students in Programa UNESP de Educação de Jovens e Adultos”. These results will demonstrate a good example of inclusive education and will prove the inadequacy of training in special education offered to Brazilian university students. In our opinion, it’s impossible to believe in diversity education without appropriate training in inclusive education because this work requires accommodation of social, political, physical, religious, cognitive and cultural differences and this demands a skilled professional in all teaching methods.
