1. Evaluation of flexural strength and antibacterial effect of orthodontic acrylic resins containing Galla chinensis extract
RESUMO Objetivo: Avaliar se diferentes concentrações de extrato de Galla chinensis (EGC) adicionado ao polimetilmetacrilato (PMMA), que é amplamente utilizado para a fabricação de aparelhos ortodônticos removíveis, interferem no efeito antimicrobiano desse extrato e na resistência à flexão do PMMA. Métodos: Foram preparadas amostras de resina a

2. Influence of mouthwashes on the physical properties of orthodontic acrylic resin
AIM: The aim of this study was to evaluate the influence of acrylic resin immersion in different mouthwashes on hardness, roughness and color. METHODS: Specimens of an orthodontic self-cured acrylic resin (Orto Clas(r)) were produced and immersed in five mouthwashes: Plax(r) Classic (Colgate(r)); Plax(r) alcohol-free (Colgate(r)); Listerine(r) (Johnson

3. Quantitative analysis of S. mutans and S. sobrinus cultivated independently and adhered to polished orthodontic composite resins
In Orthodontics, fixed appliances placed in the oral cavity are colonized by microorganisms. OBJECTIVE: The purpose of this study was to quantitatively determine the independent bacterial colonization of S. mutans and S. sobrinus in orthodontic composite resins. MATERIAL AND METHODS: Seven orthodontic composite adhesives for bonding brackets were selected an

4. Comparative in vitro study of the shear bond strength of brackets bonded with restorative and orthodontic resins
The aim of this study was to evaluate the shear bond strength of brackets bonded with different restorative systems and compare it with that afforded by an established orthodontic bonding system. Seventy human bicuspids were used, divided into five different groups with 14 teeth each. Whereas a specific orthodontic bonding resin (TransbondTM XT) was used in

5. Avaliação in vitro da dureza, da resistência adesiva e do índice de adesivo remanescentes em três resinas ortodônticas / In vitro evaluation of anical properties of three orthodontic resins
Este estudo in vitro foi conduzido para avaliar a Dureza Vickers (HV), a Resistência Adesiva (RA) e o Índice de Adesivo Remanescente de Resinas Ortodônticas. As resinas utilizadas foram divididas em 3 grupos: Concise Ortodôntico (CO), Transbond XT (TB) e Aqualite (AQ). Para a análise da Dureza Vickers (HV) foram confeccionados 30 corpos de prova em matr

6. Mechanical properties of one and two-step fluoridated orthodontic resins submitted to different pH cycling regimes
The aim of this study is to assess the in vitro shear bond strength and adhesive remnant index (ARI) of one and two-step fluoridated orthodontic resins under conditions that simulate high cariogenic challenge. Edgewise brackets for maxillary central incisors were randomly bonded to 80 bovine incisors, using either TransbondTM Plus Color Change orthodontic re

7. Preventive effect of fluoridated orthodontic resins subjected to high cariogenic challenges
O objetivo do presente estudo foi avaliar in vitro o efeito preventivo a cárie de resinas ortodônticas fluoretadas submetidas à ciclagem de pH utilizando dois tipos de saliva desmineralizadora. Bráquetes de incisivos centrais foram colados em 60 incisivos bovinos, utilizando a resina ortodôntica Transbond Plus Color Change (n=30) ou Fill Magic (n=30). C

8. Clinical and laboratory evaluation of metallic brackets bonded with orthodontic composites / Avaliação clinica e laboratorial da colagem de braquetes metalicos com compositos ortodonticos
The aim of this study was to assess clinically and laboratory the bracket failure rate and shear bond strength of metallic brackets bonded with orthodontic composites. The in vivo study consisted of 20 patients aged between 10.5 to 15.1 years old who had sought corrective orthodontic treatment. Brackets were bonded of the second premolar - second premolar to

9. Efeitos do laser de CO2 na desmineralização do esmalte ao redor de braquetes ortodonticos / Effect of CO2 laser in the enamel demineralization around orthodontic brackets
A aplicação do laser de dióxido de carbono (CO2) à estrutura do esmalte modifica a composição química e/ou morfológica dessa superfície e inibe o desenvolvimento e a progressão de lesões cariosas. Porém, não foram realizadas pesquisas que tenham verificado se a irradiação do esmalte dental ao redor de braquetes ortodônticos com esse laser é

10. Avaliação da resistência ao Cisalhamento de braquetes novos recolocados com diferentes resinas ortodônticas / Evaluation of shear bond strength of new metallic brackets rebounded with different orthodontic resins
The present study evaluated in vitro the shear bond strength of new bonded and rebounded metallic brackets with three orthodontic composites. Ninety extracted first superior premolars were randomly divided in three groups, according to the different tested composite. All bonding procedures followed the manufacturers specifications with a 300g standard pressu

11. Avaliação "in vitro" da resistência adesiva ao cisalhamento na colagem de braquetes usando dois tipos de resina
This research aims to evaluate the shear bond strenght of two resins for direct orthodontic bonding to human teeth: Concise (3M) and Ortho One (Bisco). The sample consisted in 60 caries-free premolars, which were randomly divided in two groups: group A (30 premolars with brackets bonded with Concise) and group B (30 premolars with brackets bonded with Ortho

12. Estudo comparativo da resistência adesiva da interface resina/bráquete, sob esforços de cisalhamento, empregando três resinas compostas e três tipos de tratamentos na base do bráquete / Comparative study of the shear bond strenght of the resin/bracket interface, using three different resin composites and three different treatments in the bracket-base
Analyzing the fact that, todays, the bracket/resin union is mecanic and chemically gotten, we decided to evaluate: 1) shear bond strenght of the resin/bracket interface using three commercial marks of resin composites: Concise Orthodontic (chemical-cured), Transbond XT (light-cured) and Filtek TM Z-250 (light-cured); 2) the effect, in this bond strenght, of
