Conclusions: Within the limitations of this in vitro study, it was concluded that the bond strength of lingual brackets with metal pads was higher than that of brackets with composite resin pads, due to the metal part being a single unit and welded. The failure location in the region between the bracket and the resin pad affected a higher percentage of the resin pads than the metal pads.RESUMO Objetivo: avaliar a resist ência de união ao cisalhamento de braquetes ortodônticos linguais com pads em resina e metálicos, assim como os locais de ocorrência das falhas, além do Índice de Adesivo Remanescente (ARI). Méto...

An interview with Kee-Joon Lee
ABSTRACT Root resorptions caused by orthodontic movement are not supported by consistent scientific evidence that correlate them with heredity, individual predisposition and genetic or familial susceptibility. Current studies are undermined by methodological and interpretative errors, especially regarding the diagnosis and measurements of root resorption from orthopantomographs and cephalograms. Samples are heterogeneous insofar as they comprise different clinical operators, varied types of planning, and in insufficient number, in view of the prevalence of tooth resorptions in the population. Nearly all biological events a...

Epithelial rests of Malassez: from latent cells to active participation in orthodontic movement
Conclusion: ERM cells have a functional activity in modulation of orthodontic movement, trough their potential for differentiation, maintenance functions and the capacity of repairing periodontium.RESUMO Introdu ção: os remanescentes epiteliais de Malassez (REM) se configuram como um grupo de células epiteliais presentes no ligamento periodontal, classicamente consideradas estruturas latentes ou quiescentes, associadas a processos patológicos. Entretanto, ao longo dos anos, esse paradigma vem sendo rom pido e hoje não mais são consideradas apenas como restos celulares, mas sim uma importante estrutura tecidual, co...

Angle Class III malocclusion with anteroposterior and vertical discrepancy in the final stage of growth
ABSTRACT Angle Class III malocclusion is characterized by an anteroposterior dental discrepancy with or without anteroposterior and vertical skeletal changes. Patients usually seek orthodontic treatment because facial appearance is compromised in most cases. The present study describes the clinical case of a 12-year and 6-month-old girl in her final stage of pubertal growth presenting Class III malocclusion with anteroposterior and vertical discrepancies. Initial treatment consisted of maxillary expansion using a Hass expander followed by the use of a Petit facemask for a minimum of 16 hours a day. During corrective treatm...

Is the main goal of mastication achieved after orthodontic treatment? A prospective longitudinal study
Conclusions: The present results showed that the correction of malocclusions with fixed appliances can objectively provide positive effects in both mastication and deglutition processes, reinforcing that besides aesthetic reaso ns, there are also functional indications for orthodontic treatment.RESUMO Objetivo: investigar as performances mastigat ória e de deglutição em pacientes com má oclusão, antes e após o tratamento ortodôntico, comparando-os com um grupo controle com oclusão normal, equiparado por idade e sexo. Métodos: vinte e três pacientes com má oclusão requerendo tratamento ortodôntico foram incl...

Mandibular dental arch short and long-term spontaneous dentoalveolar changes after slow or rapid maxillary expansion: a systematic review
Conclusions: There is enough evidence to conclude that negligible short and long-term spontaneous dentoalveolar changes tend to occur in the mandibular dental arch after SME or RME in the mixed and early permanent dentitions. More randomized studies with appropriate control group are required to better evaluate this issue.RESUMO Objetivo: o objetivo da presente revis ão sistemática foi analisar as alterações dentoalveolares espontâneas, em curto e longo prazos, após a expansão lenta (ELM) ou rápida (ERM) da maxila, durante a dentição mista e permanente jovem.

An interview with Steven J. Lindauer
There are so many compliments to Dr. Steven Lindauer that is hard for one to figure where to start from … Well, travelling backwards in time, all the way to the year 2000, I went to Virginia to study English at Virginia Commonwealth University (VCU), in Richmond, Virginia, USA. During my daily walks to the English school, I used to pass by the School of Dentistry, where the Department of Orthodontics was. That was the place where my very first “ contact ” with the VCU happened. In 2015, 15 years later, I had the pleasure to go back to the VCU and spend two days with Dr. Steven Lindauer. I have to confess that I was...
