Mcat podcasts

Hey everyone! Does anyone have any good suggestions for either podcasts or ebooks I could use to help study for the mcat while I commute to work? It takes me about 40 min so I think it could help be a good use of my time. I've seen reviews that ek osmosis is helpful for physics, Chem, and bio; but is there anything else out there?

ABSTRACT Dental arches areas with teeth presenting dentoalveolar ankylosis and replacement root resorption can be considered as presenting normal bone, in full physiological remodeling process; and osseointegrated implants can be successfully placed. Bone remodeling will promote osseointegration, regardless of presenting ankylosis and/or replacement root resorption. After 1 to 10 years, all dental tissues will have been replaced by bone. The site, angulation and ideal positioning in the space to place the implant should be dictated exclusively by the clinical convenience, associated with previous planning. One of the advan...

Conclusions: The present study shows the importance of a rigid design of the different components of HHEs, and also that HHEs would be s uitable for maxillary expansion in adolescents and young adults, since its mean expansion forces exceed 120N. Furthermore, early abutment detachment or smaller mini-implants diameter would only be appropriate for children.RESUMO Introdu ção: a força aplicada sobre os dentes por expansores ortopédicos fixos já foi estudada antes, mas não a força aplicada sobre os mini-implantes ortodônticos (MIOs) usados para expandir a maxila com expa...

Conclusions: Changes in the insertion angle is not a determinant factor in the positioning of miniscrews body in regions with larger interradicular space in posterior maxilla.RESUMO Objetivo: o presente estudo objetivou avaliar se altera ções no ângulo de inserção do miniparafuso são um fator decisivo para a adaptação do corpo do parafuso em áreas com espaço inter-radicular aumentado, na região posterior da maxila. Métodos: foram realizadas análises em 60 quadrantes maxilares posteriores, a partir de imagens obtidas p or tomografia co...

ABSTRACT Objective: To determine the relationship between symphysis dimensions and alveolar bone thickness (ABT) of the mandibular anterior teeth. Methods: Cone-beam computed tomography images of 51 patients were collected and measured. The buccal and lingual ABT of the mandibular anterior teeth was measured at 3 and 6 mm apical to the cemento-enamel junction (CEJ) and at the root apices. The symphysis height and width were measured. The symphysis ratio was the ratio of symphysis height to symphysis width. Kendall ’ s tau correlation coefficient was used to determine the relationships between the variables at a 0.05 ...

Conclusion: Unilateral forces promoted higher stress in root apex and higher dental tipping. The bilateral forces promoted better distribution without evidence of dental tipping. Bilateral intrusion technique suggested lower probability of root apex resorption.RESUMO Objetivos: o presente estudo teve como objetivo avaliar, por meio da An álise de Elementos Finitos, as tensões geradas por forças ortodônticas intrusivas em um molar superior e no osso alveolar circundante. Métodos: um segmento maxilar foi modelado no software SolidWorks 2010 (SolidWorks Corporation, Waltham, MA, EUA), contend...

Conclusions: The difference regarding the impact on quality of life between groups is not related to the protocol used.RESUMO Objetivo: avaliar o impacto de dois protocolos de tratamento precoce para a mordida cruzada anterior dent ária na qualidade de vida de crianças. Métodos: trinta crianças de 8 a 10 anos de idade com mordida cruzada anterior dentária participaram desse estudo. Os indivíduos foram divididos em dois grupos: Grupo 1 - 15 crianças em tratamento com aparelho removível superior com molas digitais; Grup o 2 - 15 crianças em tratamento com batente...

Conclusion: Results indicated that the surgically assisted rapid maxillary expansion might cause alterations in periodontal tissue.RESUMO Introdu ção: a expansão rápida da maxila assistida cirurgicamente (ERMAC) é um procedimento que reduz a resistência das suturas, corrigindo a mordida cruzada posterior em adultos. Objetivo: o objetivo deste estudo foi avaliar o status periodontal de 17 adultos submetidos a esse procedimento. Méto dos: o nível clínico de inserção (NCI), a recessão gengival, gengiva inserida e sangramento foram avaliados nos...

Conclusion: Anterior aesthetic and functional rehabilitation using a multidisciplinary approach was essential to improve the patient ’ s facial aesthetics, to obtain great improvement in function and to achieve occlusal stability after 2 years of follow-up.RESUMO Introdu ção: o tratamento de danos bucomaxilofaciais é complexo e requer diagnóstico abrangente e preciso, além de um correto plano de tratamento. Objetivo: o objetivo deste relato de caso foi descrever o retratamento de uma paciente do sexo feminino, 27 anos de idade, envolvida em acidente automobil ístico grave, qu...

ABSTRACT Tooth transposition is one of the most difficult dental anomalies to treat in the dental clinic. Several factors must be taken into account with a view of making the best decision. The aim of this study was to discuss treatment modalities for tooth transposition, their advantages and disadvantages. Additionally, it aims at presenting a clinical case of transposition between canine and lateral incisor in the upper quadrant on the right side. The treatment of choice was extraction of one transposed tooth. A multidisciplinary approach involving Orthodontics, Cosmetic Dentistry, and Periodontology was necessary to all...
