We are aware that all information published byeach issue of this journal needs the squeeze and sweatof thousands of people. On one end of the rope, researchersand higher education institutions work hardto produce science to the highest degree of excellence.On the other end, reviewers silently filter manuscripts,thus improving the quality and accuracy of informationthat has been approved. Science is tough, as it testsand audits one’s dreams. But both ends of the rope facethe same direction.

It is not rare to hear new patients complaining about themanifestation of traumatic injuries right after having fixedorthodontic appliances installed. There are several strategiesused by orthodontists aiming to minimize these manifestations,such as installing the appliances in stages — thusallowing the patient to get used to them — as well as usingorthodontic wax in order to protect areas that may suffertrauma. However, what can be done when traumatic injuriesappear anyway? We often use...

The tridimensional network formed by osteocytes controls bone design by coordinating cell activity on trabecular andcortical bone surfaces, especially osteoblasts and clasts. Miniplates and mini-implants provide anchorage, allowing all otherorthodontic and orthopedic components, albeit afar, to deform and stimulate the network of osteocytes to command bonedesign remodeling upon “functional demand” established by force and its vectors. By means of transmission of forces,whether near or...

While I was a PhD reciprocal exchange student at University of California, Los Angeles (UCLA), in 2011, I had thepleasure to meet great names in international Orthodontics. I was introduced to Dr. Greg Huang, a brilliant professor andan extraordinary human being. In addition to having a brilliant clinical and academic career, Dr. Huang is also chair ofone of the most renowned Orthodontics programs worldwide: at the University of Washington. Undoubtedly, thanks toDr. Huang, Orthodontics has...

Objective: This article aimed to evaluate in vitro the efficiency of Pro Seal fluoride sealant application in the preventionof white spot lesions around orthodontic brackets.Material and Methods: Brackets were bonded to the buccal surface of bovine incisors, and five groups were formed(n = 15) according to the exposure of teeth to oral hygiene substances and the application of enamel sealant: G1 (control),only brushing was performed with 1.450 ppm fluoride; G2 (control) brushing associated...

Objective: To determine the cephalometric parameters and esthetic preferences of a pleasant face for the Japanese population.Methods: For the present study, the following databases were accessed: PubMed, Embase, Scopus and Web of Science.Initial inclusion criteria comprised studies written in English and quoting cephalometric norms and/or facial attractivenessin Japanese adults. No time period of publication was determined. The quality features evaluated were sample description,variables...

Introduction: Patients with dentofacial deformities may undergo orthodontic or orthodontic-surgical treatment.Both modalities can affect esthetics.Objective: This study aims to evaluate clinical and radiographic changes in exposure of maxillary central incisors occurringafter orthognathic surgery for maxillary advancement.Methods: A total of 17 patients who underwent orthognathic surgery for maxillary advancement between September,2010 and July, 2011 were selected. Exposure of maxillary...

Objective: This study aimed at assessing the relationship between facial morphological patterns (I, II, III, Long Faceand Short Face) as well as facial types (brachyfacial, mesofacial and dolichofacial) and obstructive sleep apnea (OSA) inpatients attending a center specialized in sleep disorders.Methods: Frontal, lateral and smile photographs of 252 patients (157 men and 95 women), randomly selected from apolysomnography clinic, with mean age of 40.62 years, were evaluated. In order to...

Objective: The aim of this study was to compare torque expression in active and passive self-ligating and conventionalbrackets.Methods: A total of 300 segments of stainless steel wire 0.019 x 0.025-in and six different brands of brackets (Damon3MX, Portia, In-Ovation R, Bioquick, Roth SLI and Roth Max) were used. Torque moments were measured at 12°, 24°,36° and 48°, using a wire torsion device associated with a universal testing machine. The data obtained were comparedby analysis of...

Objective: To determine the prevalence of malocclusion and orthodontic treatment need in a large sample of CentralAnatolian adolescents and compare them with European-other nations’ adolescents.Methods: The sample included 1125 boys and 1204 girls aged between 12 and 16 years with no previous orthodontictreatment history. Occlusal variables examined were molar relationship, overjet, overbite, crowding, midlinediastema, posterior crossbite, and scissors bite. The dental health (DHC) and...

Introduction: Narrow airway dimensions due to mandibular deficiency can predispose an individual to severe respiratorydistress. Hence, treatment with mandibular advancement devices at an early age might help improving the pharyngealpassage and reduce the risk of respiratory difficulties. Therefore, the aim of the current study was to evaluate themean changes in the pharyngeal dimensions of children with mandibular deficiency treated with Clark’s twin-blockappliance (CTB) followed by fixed...

Objective: Evaluation of the force system produced by four brands of β-Ti wires bent into an elaborate design.Methods: A total of 40 T-loop springs (TLS) hand-bent from 0.017 x 0.025-in β-Ti were randomly divided into fourgroups according to wire brand: TMATM (G1), BETA FLEXYTM (G2), BETA III WIRETM (G3) and BETA CNATM (G4).Forces and moments were recorded by a moment transducer, coupled to a digital extensometer indicator adapted to atesting machine, every 0.5 mm of deactivation from 5 mm...

Class III skeletal pattern is characterized by disharmony between maxillary and mandibular basal bones anteroposteriorly,and might or might not be associated with dental changes. In general, facial esthetics is hindered significantly, which mostof times is the reason why patients or patient’s guardians seek treatment. This case was presented to the Brazilian Boardof Orthodontics and Dentofacial Orthopedics (BBO) in partial fulfillment of the requirements for Diplomate recertificationand...

The term “asymmetry” is used to make reference to dissimilarity between homologous elements, altering the balancebetween structures. Facial asymmetry is common in the overall population and is often presented subclinically. Nevertheless,on occasion, significant facial asymmetry results not only in functional, but also esthetic issues. Under theseconditions, its etiology should be carefully investigated in order to achieve an adequate treatment plan. Facial asymmetryassessment comprises...
