Comparison of the reproducibility of two cervical vertebrae maturation methods
Duque,Paulo Henrique da Rocha; Santiago,Rodrigo César; Santos,Rogério Lacerda dos; Faria,Fernanda Ramos de; Werneck,Carolina de SáAim Facial orthopaedic treatments based on the stimulation or restrictions of craniofacial bone growth are more effective when carried out during the pubertal growth spurt. The aim of this cross-sectional study was to evaluate the reproducibility of two cervical vertebrae methods (CVM) with manual tracing and direct visual inspection. Methods A sample of 60 lateral cephalometric radiographs (10 of each of the 6...
Evaluation of the prototype of a new bracket-positioning gauge
Mota Júnior,Sergio Luiz; Campos,Marcio José da Silva; Schmitberger,Carina Abrantes; Vitral,Juliana de Andrade; Fraga,Marcelo ReisABSTRACT Objective: The purposes of this study were to present a prototype of a bracket-positioning gauge, which makes vertical inclination of the instrument difficult, allowing a reduction of vertical bracket positioning error, and to test its accuracy in bracket positioning by groups of individuals with different clinical experience and in specific groups of teeth. Methods: For the testing of the prototype, f...
Plain access to justice and the orthodontist’s activity in Brazil: vulnerabilit...
Guedes,Cleverson Raymundo Sbarzi; Leite,Isabel Cristina Gonçalves; Campos,Marcio José da Silva; Mota Júnior,Sergio Luiz; Phiton,Matheus MeloABSTRACT Objective: the present study aimed at evaluating the risks and vulnerability of orthodontists to legal compensation actions and verifying the hypothesis of these health care professionals having little knowledge concerning their rights and obligations as service providers. Methods: Three groups were formed to participate in a semi-structured interview. The first group had thirteen law professionals, th...
Shear bond resistance and enamel surface comparison after the bonding and debon...
Rocha,José Maurício da; Gravina,Marco Abdo; Campos,Marcio José da Silva; Quintão,Cátia Cardoso Abdo; Elias,Carlos Nelson; Vitral,Robert Willer FarinazzoOBJECTIVE: To evaluate, in vitro, the shear bond strength presented by three brands of polycrystalline ceramic brackets and one brand of metallic bracket; verify the adhesive remnant index (ARI) after the tests, and analyze, through scanning electron microscopy (SEM) the enamel surface topography after debonding, detecting the release of mineral particles. METHODS: Sixty bovine lower incisors were used. Three c...
The influence of patient's motivation on reported pain during orthodontic treat...
Campos,Marcio José da Silva; Vitral,Robert Willer FarinazzoINTRODUCTION: Patients usually experience pain during orthodontic treatment. This fact can affect cooperation and the development of treatment. Reporting pain during treatment seems to be influenced by emotional aspects such as the patient's motivation. OBJECTIVE: To assess the relationship between patient's motivation and the intensity of reported pain during two stages of treatment. METHODS: Twenty males (11-...
Assessment of pain experience in adults and children after bracket bonding and ...
Campos,Marcio José da Silva; Fraga,Marcelo Reis; Raposo,Nádia Rezende Barbosa; Ferreira,Ana Paula; Vitral,Robert Willer FarinazzoINTRODUCTION: Ninety five percent of orthodontic patients routinely report pain, due to alterations in the periodontal ligament and surrounding soft tissues, with intensity and prevalence varying according to age. OBJECTIVE: This study aimed to assess toothache and buccal mucosal pain in adults and children during two initial phases of the orthodontic treatment. METHODS: The intensity of toothache and buccal mu...
Clinical evaluation of dental alignment and leveling with three different types...
Gravina,Marco Abdo; Brunharo,Ione Helena Vieira Portella; Fraga,Marcelo Reis; Artese,Flavia; Campos,Marcio José da Silva; Vitral,Robert Willer FarinazzoINTRODUCTION: A wide variety of orthodontic wires made of different alloys is available to be used in orthodontic practice and may produce different clinical responses during tooth movement. OBJECTIVE: This research evaluated the alignment and leveling of lower dental arches after the use of three types of orthodontic wires. METHODS: A sample of 36 patients was randomly divided into 3 groups: stainless steel, m...
Prototype of a new tip developed to be coupled to dental light-curing units for...
Mota Júnior,Sergio Luiz; Campos,Márcio José da Silva; Gravina,Marco Abdo; Fraga,Marcelo Reis; Vitral,Robert Willer FarinazzoOBJECTIVE: development of a new device to be coupled to light-curing units for bonding orthodontic brackets and accessories, and test its efficacy in an in vitro mechanical trial. The inner surface of the device is mirrored and is based on physical concepts of light refraction and reflection. The main advantage of such device is the reduced clinical time needed for bonding and the low possibility of contaminati...
Efeito da amarração em Ortodontia, com ligaduras elastoméricas e de aço inoxidá...
Rodrigues,Clotilde Freitas; Sales,Lígia de Araújo Ramos; Vitral,Robert Willer Farinazzo; Fraga,Marcelo Reis; Quintão,Cátia Cardoso AbdoOBJETIVO: o presente estudo avaliou clinicamente as condições periodontais de um grupo teste e um grupo controle utilizando-se os seguintes três sistemas de indexação periodontal: índice de biofilme, índice de sangramento e profundidade de sondagem. MÉTODOS: o grupo teste foi composto por 20 indivíduos com média etária de 13,5 anos, submetido ao tratamento ortodôntico fixo, que recebeu duas formas de ligaduras:...
Densidade mineral óssea de sítios específicos da maxila para a inserção de mini...
Santiago,Rodrigo César; Cerrone Júnior,Giovanni; Vitral,Robert Willer FarinazzoOBJETIVOS: avaliar a Densidade Mineral Óssea (DMO) de sítios específicos na maxila, por meio da Tomografia Computadorizada (TC) Multi-Slice. METODOLOGIA: foram realizadas 15 TC Multi-Slice da maxila para a avaliação da densidade mineral óssea de 30 regiões de interesse entre os segundos pré-molares e primeiros molares - 15 do lado direito e 15 do lado esquerdo - de 15 indivíduos (7 homens e 8 mulheres, com idad...
