1. Alterações cefalométricas produzidas pelos aparelhos Distal Jet e Pendulum no tratamento da má oclusão de Classe II / Cephalometric changes produced by the distal jet and pendulum appliances for the treatment of Class II malocclusion
A proposta deste estudo consistiu em comparar, por meio de telerradiografias em norma lateral, as alterações dentoesqueléticas e tegumentares promovidas pelos distalizadores intrabucais Distal Jet e Pendulum, seguidos do aparelho fixo corretivo, e compará-los a um grupo controle. O grupo 1 constituí-se de 20 pacientes, 15 do gênero feminino e 5 do masc

2. Evaluation of influence of DICOM and JPEG formats in the reproducibility of cephalometric landmarks in digital Frontal Teleradiographies / Avaliação da influência dos formatos DICOM e JPEG na reprodutibilidade de pontos cefalométricos em Telerradiografia digital em Norma Frontal
The digital image on DICOM format request a large store size capability, making difficult the transmission through internet, usually requesting the image compression via JPEG file format. The aim of this study was to evaluate the influence of DICOM and JPEG file formats on Quality Factors 100, 80 and 60, in the reproducibility intra and interexaminer at ceph

3. Cephalometric evaluation of the stability post rapid maxillary expansion surgically assisted / AVALIAÇÃO CEFALOMÉTRICA DA ESTABILIDADE PÓS-EXPANSÃO RÁPIDA DA MAXILA ASSISTIDA CIRURGICAMENTE
This study evaluated the stability of the dental and skeletal changes produced by Rapid Maxillary Expansion Surgically Assisted (RMESA), in transversal and vertical dimensions. The sample selected for this retrospective study comprised 60 posteroanterior cephalograms, of 15 patients, being 6 males and 9 females, with mean age of 23,3 years old. An Hyrax appl

4. Cephalometric study of skeletal, dental and soft tissue structures in white, black and afrocaucasian young Brazilian descents with normal occlusion / Estudo cefalométrico das estruturas esqueléticas, dentárias e tegumentares, em jovens brasileiros, leucodermas, feodermas e melanodermas, com "oclusão normal"
Actually, metropolitan areas have diverse populations, with a need to recognize that a standard of facial esthetics might not be appropriate when making orthodontics diagnostic and treatment plans for patients from various racial and ethnic backgrounds that migrated to distinct geographic bounds. With the purpose of using a specific cephalometric standard fo

5. Correlação entre os planos cefalométricos e a linha vertical verdadeira em telerradiografias de perfil obtidas na posição natural de cabeça em pacientes com padrão facial I, II e III / Correlation between cephalometric planes and true vertical line in lateral cephalograms obtained in natural head positioning in patients with facial pattern I, II and III
This study evaluated the relationship between cephalometric planes and the true vertical line on lateral cephalograms obtained in natural head positioning, from individuals with different facial patterns. The sample comprised 28 individuals (15 females and 13 males), aged 17 to 37 years, with complete dentition at least up to the first molars without previou

6. Electromyography activity of masseter and temporal muscles in individual with different vertical facial types / Atividade eletromiografica dos musculos masseter e temporal em individuos com diferentes tipos faciais verticais
The influence of masticatory muscles over the facial morphology is important to comprehend the normal growth and the manifest of morphological anomalies. The objective of this study was to evaluate the electromyographic activity of masseter and temporal muscles among individuals with different vertical facial types. The sample was composed by forty-four volu

7. ANÁLISE CEFALOMÉTRICA COMPARATIVA ENTRE CRIANÇAS RESPIRADORAS BUCAIS E NASAIS / Comparative cephalometric analysis between mouth breathing and nose breathing children
There are several controversies on the real interference from breathing on craniofacial growth. This study evaluated the possible relationship of the influence of breathing pattern with cephalometric variables: 1) sagittal skeletal variables: convexity of point A, facial depth, maxillary depth and mandibular body length; 2) vertical skeletal variables: lower

8. Cephalometric radiographic study of soft tissue profile changes in Class I patients after orthodontic treatment with first premolars extractions / "Estudo cefalométrico-radiográfico das mudanças no perfil tegumentar de pacientes com maloclusão de classe I tratados com extrações de primeiros premolares"
O objetivo desta pesquisa foi realizar um estudo cefalométrico radiográfico com o propósito de avaliar as mudanças no perfil tegumentar do terço inferior da face em casos com maloclusões de Classe I, biprotrusos, tratados ortodonticamente com extrações de quatro premolares, por meio da técnica do arco contínuo preconizada por Roth. A amostra consto

9. Alterações maxilares apos o uso do gancho "J" na distalização dos caninos
The present study had the objective to observe the changes of the maxilla during the Denture Preparation phase, the initial stage of the treatment according to the Edgewise Sequential Directional Force System introduced by MERRIFIELD in 1986. In this study a set of 30 cephalometrics radiographies were taken from Brazilian withe individuaIs, from age 12 to 16

10. Alterações cefalometricas em individuos dolicofaciais, com maloclusão de classe III, submetidos ao tratamento ortodontico-cirurgico
Among several malocclusion forms is the Class 111 malocclusion, which may be dental or skeletal. As decisive characteristic, the skeletal Class 111 malocclusion shows the bad relantionship between the osseous bases that may be the result of deficient evolution of the maxillary, excessive growth of the mandible, or even both. For these kinds of malocclusion,

11. O efeito sobre as medidas cefalometricas devido a alteração da posição natural da cabeça (PNC) em telerradiografias tomadas em norma lateral
Em 1884, craniologists adopted the Frankfurt horizontal plane, determined by the left Porion, right Porion and left Orbitale points, as being the reference that defines the head position while parallel to the soil. When of the appearance of the cephalometry, countless points, lines and reference planes were used in craniometry, among them the Frankfurt horiz

12. Estudo sobre a influencia do plano de orientação de Frankfurt alterado em +5o. e -5o. , nas mensurações verticais e angulares em telerradiografias postero-anteriores
The Frankfort horizontal plane is generally used as orientation plane, but the difficulty of obtaining correct parallelism in relation to horizontal, become difficult the reliability measures in studies craniofacial of postero anterior cephalometry. The sample consisted of 30 patiénts, each one was taken posteroanterior cephalometry in three positions: Fran
