Surgical-orthodontic tractio for impacted maxillary canines: a critical review and suggested protocol

Maxillary canine impaction is a common occurrence, especially in the palate, despite sufficient space in the arch for tooth alignment. A proper approach requires knowledge of different specialties of dentistry, such as orthodontics, surgery, radiology, and periodontology, which are generally not centered on a single professional. The causes for canine impaction may be either generalized or localized, and the diagnosis should be made through specific clinical and radiographic examination. The prognosis of surgical-orthodontic treatment depends on the position of the canine in relation to the neighboring teeth and height of the alveolar process, in addition to careful surgical technique, considering that there are risks involved, such as ankylosis, loss of tooth vitality, root resorption of the involved tooth and adjacent teeth, and damage to supporting tissues. Given the important role played by impacted maxillary canines, their traction is the treatment of choice in orthodontically treated patients. The present study reviews the literature on important factors to be considered when approaching impacted canines, such as therapeutic possibilities, their advantages and disadvantages.

Princípios de redução das fraturas panfaciais: revisão de literatura

Are called panfacial fractures when the upper, middle and lower facial thirds present fractures concurrently. In clinical practice, came to imply the involvement of two facial thirds. Panfacial fractures are usually accompanied by other systemic lesions that impair the patient's life and therefore require primary treatment. Almost invariably are associated with damage to soft tissues and severe losses of bone structures which may lead to severe facial deformations and malocclusions. The panfacial fractures treatment is complex because often there isn’t a stable bone structure to guide the reduction of various fractures. Several orders of treatment have been proposed, but they are variations of the two classical approaches "bottom to top and inside-out" and "top to bottom and out-inside". The aim of this paper is to discuss the principles of management and panfacial fractures treatment, emphasizing the sequence of fracture reduction and highlighting its indications, advantages and disadvantages, through literature review and reports of surgical clinic cases. We conclude that the exact sequence of fracture reduction is not as important as developing a treatment plan that allows accurate positioning of the fractured segments.

Detecção de microrganismos de infecções bucais: perspectivas e cuidados a serem seguidos

The diagnosis of head and neck infections constitutes relevant step in their treatment. However, in spite of the fact that most of diseases in head and neck region are infectious in nature, several reasons collaborated for dentists do not ask laboratory tests in order to help clinical diagnosis. By mean of this review literature, based on research articles about the newest and most reliable methods of diagnosis for clinical laboratories, the authors discuss the advantages and disadvantages of each selected method and the relevant aspects in transportation of the specimens to the laboratory. Saliva, biofilm, pus, and blood are the most frequent specimens for microbial diagnosis, being that the most used methods are culture and those based on detection of deoxyribonucleic acid by polymerase chain reaction method. Whereas, the culture depends on cellular viability, and has reduced sensitivity, as well as needs favorable conditions in the sample collection and transportation, PCR shows high sensitivity and specificity, but it does not allow the determination of antibiogram, what reduces its usefulness. In addition, few laboratories possess conditions to perform cultivation of obligate anaerobes or have experience in the molecular detection of these microorganisms.

Condutas terapêuticas para caninos inclusos

Normally, the last teeth to erupt are the ones which remain impacted or semi-impacted, and that is the case of the canines. This study aimed to report a few options of treatment, aiming at esthetic and functional maintenance of the affected area before a impacted canine, discussing its indications, contraindications, advantages and disadvantages. This study also aims to emphasize the accessibility the patient would have in case his/her option were one of the approached ways of treatment. In order to identify the studies included or analyzed in this review, a detailed search strategy was performed for the database used: Pubmed, Bireme, Scielo, Cochrane, and Dentistry Oral Science up to 2011. We used non-erupted teeth, canine, and therapeutics as descriptors. The criteria of inclusion were clinical and review articles that approached the theme. Through this review, it was found that the surgeon dentist’s lack of technical and scientific knowledge and the financial impossibility of most population are some hindrances for the establishment of the right planning for the impacted canine.

Osteoporose: considerações sobre terapêuticas atuais e metabolismo ósseo

O processo de remodelação óssea é regulado por fatores sistêmicos e locais. Estrógeno é o hormônio mais importante na manutenção do turnover ósseo normal, cuja deficiência leva a alterações na remodelação óssea com reabsorção excedendo a formação, como observado em mulheres pós-menopausadas. O tratamento da osteoporose está relacionado com a descoberta de fármacos alternativo à terapia hormonal estrogênica compensando as desvantagens dessa terapêutica. O Raloxifeno (RLX) mimetiza os efeitos benéficos do estrógeno sem estimular tecidos como mama e endométrio. O Fluoreto de sódio (NaF) apresenta-se como agente eficaz no combate às fraturas, conseqüentes da osteoporose.

Inovações tecnológicas e contexto escolar: reflexões necessárias

In modern society technologies have played an important space exerting influences in different spheres. Today's young people are born immersed in the digital and virtual reality, which has changed the ways of learning, as well as to relate to the world. All this context has intensified the debate on the potential of ICT in education and training means. In this study, we sought to investigate the teachers' vision of ICT in the school environment, how they are being incorporated into the school and the limits and possibilities of the use of ICT in the learning process. Questionnaires were administered to 150 teachers who teach in high school in the state network of São Paulo teaching, but specifically in Piracicaba. Continuing, semi-structured interviews with a group of 8 directors were carried out so that there was a deepening on the issues raised by teachers in the questionnaire. The research brought to light important issues for discussion and referral measures striving to support public policies of integration of ICT in schools. Teachers spoke about the advantages and disadvantages of their use and the process of integration. It was observed that, despite efforts to implementation, there are still problems with infrastructure of schools, teacher training and working conditions
