An interview with David Normando
This study contributes to the understanding of the mechanisms associated with signs and symptoms of tooth eruption, by investigating the presence of mast cells in pericoronal tissues during the intraosseous (Group 1) and submucosal (Group 2) phases of eruption. We compared findings for these two groups with each other and with those for the oral mucosa (Group 3). In each group, 14 specimens were analyzed microscopically after hematoxylin and eosin staining and immunohistochemical analysis of c-Kit and tryptase expression. Results revealed that the number and density of mast cells is different in follicular tissues accordin...

ERRATUM: Effect of supplementary zinc on orthodontic tooth movement in a rat model
ABSTRACT A canted occlusal plane is the cause of unaesthetic smile, and also represents a challenge, due to the complex orthodontic procedures involved in its treatment. The skeletal anchorage allows successful treatment of this asymmetry in the majority of cases, with less dependency on the patient cooperation and reducing the necessity of orthognatic surgery. Given this condition, this article aims at discussing the main aspects related to the diagnosis of occlusal plane canting, treatment plan, and orthodontic mechanics using skeletal anchorage either by mini-implants or miniplates. In this context, five cases will be r...

Orthodontic traction of impacted canines: Concepts and clinical application
ABSTRACT Orthodontic traction of impacted canines stands as a major challenge for Orthodontics. It is a relatively frequent clinical complaint which management, more often than not, requires a multidisciplinary approach. Surgical exposure of the impacted canine, and the complex orthodontic mechanics applied to align the tooth back into the arch, may frequently lead to complications involving supporting tissues, not to mention the long treatment time and high costs imposed to patients. In face of that, it is worth highlighting the relevance of early diagnosis as to intervene efficiently and as soon as possible. This paper p...

Influence of heat treatment on the mechanical properties of CrNi stainless steel orthodontic wires
Conclusion: From the findings of this study, it can be conclude that the mechanical behavior of heat-treated stainless steel archwires is similar to that of archwires not subjected to heat treatment.RESUMO Introdu ção: o tratamento térmico de fios de aço inoxidável é um procedimento clÃnico rotineiro adotado por muitos cirurgiões-dentistas para aliviar o estresse causado após a confecção de dobras no fio. O presente estudo avaliou a influência do tratamento térmico em fios de aço inoxidável co m secção retangular de 0,016 ’ ’ x 0,022 ’ ’ . M étodos: para análise da estabilidade dimensional, f...

Do laypersons perceive aesthetic differences between coated and uncoated orthodontic archwires?
Conclusions: The results indicated that the aesthetic coated archwires represent an improvement in the visual aspect of ceramic brackets. The epoxy-coated metal wire was considered the most aesthetic option.RESUMO Introdu ção: rotineiramente na terapia ortodôntica fixa, utilizam-se braquetes estéticos combinados com fios metálicos, principalmente devido a algumas desvantagens no uso clÃnico dos fios estéticos. A percepção estética dos leigos nessa situação precisa ser explorada na literatura. Objetivo: o objetivo deste estudo transversal foi avaliar a percepção estética dos leigos em relação aos fios o...

Influence of maxillary canine torque variations on the perception of smile esthetics among orthodontists and laypersons
Conclusions: The present findings indicated that smiles with unilateral palatal (negative values) maxillary canine torque variations were more tolerated than smiles with buccal crown torque (positive values) variations.RESUMO Objetivo: o objetivo do presente estudo foi avaliar a percep ção estética do sorriso, por ortodontistas e leigos, em relação a variações unilaterais do torque do canino superior, em uma análise frontal do sorriso. Métodos: foram utilizadas fotografias de face total e de sorriso aproximado de dois indivÃduos (1 homem e 1 mulher). Ambos os sorrisos e xibiam dentição anterossuperior saudÃ...

Evaluation of conformity of preformed orthodontic archwires and dental arch form
Conclusion: No single commercially available archwires evaluated in the present study conformed to the arch dimensions of our subjects. Utilization of the currently available archwires may result in unwarranted modification of arch form, which may lead to unstable post-treatment teeth position.RESUMO Introdu ção: as alterações no formato da arcada dentária durante o tratamento são ditadas pelas dimensões do arco ortodôntico. Objetivo: o presente estudo teve como objetivos determinar a dimensão média das arcadas dentárias de pacientes paquistaneses e avaliar a conformidade entre diferentes a rcos ortodônticos...

Effect of different stripping techniques on pulpal temperature: in vitro study
Conclusion: Frictional heat produced with different stripping techniques results in increase in the pulpal temperature, therefore, caution is advised during this procedure. A coolant spray can limit the increase in temperature of the pulp.RESUMO Introdu ção: o desgaste proximal do esmalte é um procedimento clÃnico rotineiro utilizado na Ortodontia para se criar espaços ou equilibrar discrepâncias de tamanho dentário. Esse procedimento pode resultar em transferência de calor para a polpa, predispondo-a a mudanças histopatológicas e necros e do tecido pulpar. Objetivo: medir as mudanças de temperatura na câma...

Why canines induce resorption of neighboring roots? An imaging correlation
ABSTRACT Despite the explanations about the mechanisms and reasons why dental follicles of unerupted maxillary canines do not cause root resorption in neighboring teeth, questions remain about the time expected for this event and the lack of protocols for preventive clinical management, which may serve as insights for further studies. Here, these mechanisms are correlated with imaging findings of CT scans and 3D reconstructions of a typical clinical case.RESUMO Apesar das explica ções dos mecanismos e dos porquês os folÃculos pericoronários dos caninos superiores não irrompidos podem reabsorver as raÃzes dos dentes ...
