Aplicação da análise de jarabak, no estudo da relação entre a altura total facial anterior e posterior, em pacientes portadores de má-oclusão de classe I e classe II divisão 1 de angle, por meio de radiografias cefalométricas

ln order to predict the facial growth using Jarahak's analysis, cephalometric radiographies of 120 subjects during the mixed dentition and between 6 and 10 years of age were studied. From the total, 60 subjects (30 males and 30 females) were classified as Angle's Class I and 60 subjects (30 males and 30 females) were classified as Angle's Class II, Division 1. AIl subjects did not receive any orthodontic treatment. The proportion between anterior and posterior facial heigth (SGo-NMe) was studied, which is determined by the formula PFH x 100/ AFH = %, neither being straight (> 62% < 65), clockwise ( > 58% < 62%) and anti-clockwise ( > 65% - 80%). Mean average, standard deviation and facial height proportion (SGo - NMe) were determined for males and females according to Angle's classification of malocc!usion. Sexual dimorphism was examined with regard to different types of Angle's malocclusion and the direction of the facial growth, and the correlation of four cephalometrics measurements were analvsed

Acessos cirúrgicos a articulação temporomandibular: revisão de literatura

The choice of surgical approach to diseases that affect the pre-auricular region has been subject of much discussion in the literature. Access pre-hearing, have been used with high compliance rate of success, and during the history of surgery, several modifications were made in this approach with the goal of reducing the irreversible consequences especially regarding common in condylar fractures as paralysis and facial scars. The views range from the indication of surgical treatment for all fractures, until the conviction that no fracture of the bone segment should be surgically treated. Therefore, this study is of relevance, since offers surgeons warn about the care on the anatomical structures involved in these surgical approaches and describe, seeking a comparison between them, the advantages of them by means of a literature review covering from the extensive bouts of Bellinger (1940) and Al-Kayat (1979) that provide a broad view of the surgical field to access modified and increasingly smaller as the endaural (2001) which not only allows a satisfactory field of aesthetics as maintenance the patient without any signs of scarring.

Trauma traqueal associado à fratura mandibular: relato de caso

Introduction: The mandibular injuries account for about 20% to 50% of cases of facial fractures. Some consider the jaw the second most commonly fractured bone of the skull, and is the only mobile bone of the facial framework, which results in decreased stability compared to the trauma. When one takes into account the degree of airway obstruction in patients with facial fractures, the problem becomes much more serious since it is one of the most troubling complications of trauma. Objective: the relevance of the topic is aimed to report a case of a patient victim of mandibular fracture associated with trauma to the trachea. Case report: Case report: Patient 24 years old patient with tracheal trauma concomitant mandibular fracture surgically treated in conjunction with the thoracic surgeon. After 5 months postoperatively, the patient is in good condition general, no complaints. Final comments: This form is observed that the key to proper treatment of tracheal trauma associated with facial fractures is the knowledge of the type of injury, and an accurate diagnosis multidisciplinary.

This sequence aims to instruct and warn those who work with dentures about the needs of using face bows for correct reproduction of the models positioning in the articulator

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.

Case report: Cornelia de Lange Syndrome (CDLS)

The Cornélia of Lange´s syndrome is a genetic anomaly, described and published by Cornelia Catharina of Lange in 1933, however, their aspects were described previously by Winfried Robert Clemens Brechmann in 1916, that’s why it is also known as Brachmann of Lange’s syndrome. The most frequent clinical characteristics include typical face dismorfia, variable degree of mental delay, anomalies of the hands and feet, multiple malformations, retardation of the pre and postnatal physical development and microcephaly variable intellectual compromising. Some facial characteristics are peculiar and they are mixed with the inherited lines of their own family, the united brows, the long lashes, the small nose, the round face, the fine lips and lightly inverted. As oral manifestations they present micrognathia, dental crowding, periodontal disease, delayed dental eruption, enamel hypoplasia, erosion of the enamel and dentine caused by stomach acids of the gastroesophageal reflux and atresia of the dental arches. The purpose of this paper is to present a clinical report of a boy bearer of this syndrome assisted at CAOE - FOA - UNESP, emphasizing the importance of multiprofessional team for the diagnosis and treatment of this syndrome.

Doença de Lyme na região de cabeça e pescoço: implicações para a odontologia

Lyme disease (LD) is a systemic inflammatory changes resulting from the direct action of the spirochete Borrelia burgdorferi on the host or indirect damage produced by immune response to this microorganism. This pathogen is transmitted by inoculation in the bloodstream by the tick genus Ixodes and is most commonly found in North America, Europe and Asia. In these regions, the dental community is aware about its commonest clinical symptoms, collaborating with the establishment of a diagnosis. However, in Brazil, the frequent facial or peripheral neurological manifestations, among them the Bell's palsy, ocular disorders, disorders in the temporomandibular joint, as well as paresthesia of upper and lower alveolar nerves are observed. In our country, the diagnosis of Lyme disease is primarily based on clinical symptomatology, but most of cases remain without diagnosis and treatment. Then, the detection of the early manifestations of Lyme disease by health professionals is essential for the proper antibiotic treatment, preventing the progression of the disease, and allowing the establishment of favorable prognostic.

Implicações clínicas da doença de Lyme em região facial: revisão da literatura

Lyme disease (LD) is a systemic infl ammatory changes resulting from direct action and the immune response to the spirochete Borrelia burgdoferi transmitted by inoculation of the fl ow of the genus Ixodes tick and is most commonly found in North America, Europe and Asia. This disease can lead to facial and peripheral neurological manifestations, such as Bell’s palsy, eye changes, disorders in the temporo-mandibular joint in addition to paresthesia of superior and inferior alveolar nerves. In Brazil, the diagnosis of LD is primarily based on clinical presentation, the erythema migrans skin, and epidemiological information of the patient. Recognition of the onset of the DL by health professionals is essential for the correct antibiotic treatment preventing the progression of the disease, and also relevant preventive guidelines for those living or working in endemic areas.

Reconhecimento de faces sob diferentes condições de iluminação utilizando PCA e a transformada census

Os seres humanos identificam naturalmente outros seres humanos utilizando suas características físicas, fisiológicas ou comportamentais. Dentre essas características, destacam-se os traços faciais. O avanço tecnológico na área de Biometria tem promovido o desenvolvimento de inúmeras técnicas para o reconhecimento automático de faces por meio de computadores, entretanto, existem ainda vários fatores que dificultam esta aplicação, como por exemplo, a variação das condições de iluminação. O objetivo deste artigo é analisar os efeitos da aplicação de um filtro de processamento de imagens, denominado Transformada Census, em uma base de dados com imagens da face em diferentes condições de iluminação. Assim, experimentos foram realizados utilizando a técnica PCA com imagens da base de dados AR antes e depois da aplicação da Transformada Census. Os resultados desses experimentos mostraram que a aplicação da Transformada Census melhorou o resultado do reconhecimento das faces, reduzindo a taxa de erro.
