Myth and evidence in palatal expansion
Untruths and distortion of scientific findings inhabit the medical and dental fields, not intentionally but often because of the lack of firm evidence. The aim in this paper is to visit a common orthodontic treatment modality, palatal expansion, and explore whether the accumulated biologic and mechanical findings are sufficient or misinterpreted for proper intervention. Specifically, questions are raised regarding the sutural response to maxillary widening in relation to the age-related changes in the morphology of the suture. (Source: Seminars in Orthodontics)

The role of orthodontics, orthognathic surgery and adjunct surgical procedures in the esthetic rehabilitation of the face and smile: potential and limitations.
For nearly a century, orthodontists have mainly focused on occlusion as the primary objective of orthodontic therapy. The introduction of the soft tissue paradigm has shifted treatment planning from hard tissue to soft tissue and reinforced the key role of facial esthetics in orthodontic diagnosis and treatment planning. Whereas occlusion is rooted in measurable definitions of Class I and other “keys to occlusion”, esthetics is more subjective, based not only on the orthodontist's assessment but also on personal and cultural preferences rather than rigid norms.

The surge of finite element analysis in the study of orthodontic mechanics: are the findings applicable in practice?
Finite element (FE) analysis has emerged as the primary tool to investigate complex problems that are difficult to test clinically on living tissues, yielding valuable but not necessarily applicable information on orthodontic treatment modalities. Many studies are being published but the findings are difficult to interpret, lack in relevance, or cannot be critically appraised. In this paper, the FE modeling design and impact on the quality and outcome of research are discussed, with focus on how to narrow the gap between theory and clinical application.

Treatment of Class II malocclusion in the growing patient: Early or late?
The aim of this paper is to evaluate several factors that can improve the efficacy of Class II treatment in the growing patient with mandibular skeletal retrusion. Previous research has shown that functional appliances are most effective in altering short-and long-term mandibular growth and mandibular sagittal position if active treatment includes the pubertal growth spurt. If functional jaw orthopedic treatment is initiated in the prepubertal growth period, the positive occlusal changes are primarily dentoalveolar in nature. (Source: Seminars in Orthodontics)

Enabling and restricting functions of the overjet in orthodontic treatment
The aim is to evaluate the functions of the overjet in mediating, aggravating, and enabling the expression of jaw growth in growing patients with Class II division 1 and Class III malocclusions. Beside malocclusion severity and treatment timing, treatment duration warrants special consideration, contrasting shorter-term (2-3 years) and longer-term (5-7 years) responders to treatment, both encompassing the contribution of the adolescent growth spurt. Analysis of the genetic and environmental components affecting the development of malocclusion and growth modification indicates that varying critical periods of growth among t...

The translation of research central tendencies in clinical practice: power and limitations of statisticsFTP
The clinician's ability to provide evidence-based orthodontics is directly related to their adeptness at dissecting published research, which in turn is heavily dependent on the proper understanding of the tenets of research design and biostatistics. Using relevant clinical examples, we discuss key principles affecting the translation of the results of single research studies into clinical practice, including effect modifiers and confounders, study design, central tendency and outliers. The application of the same scrutiny to higher level meta-epidemiological evidence is also illustrated in addition to a detailed discussio...

Cross-bite Correction in Mixed Dentition : Rationale and Clinical Recommendations
There is a wide consensus that anterior and posterior crossbite (AXB / PXB) should be corrected early and that the first stage of the mixed dentition may be the best time to correct not only the occlusion of permanent molars and/or incisors, but also the maxillary deficiency / narrow palate and the mandibular shift often associated to the A/PXB.Many methods have been proposed in the literature aimed to correct AXB and PXB. In this paper a new, or at least uncommon, method will be presented to correct AXB and/or PXB in the mixed dentition, paying special attention to many important and often not considered details concernin...

Growth: sometimes a friend, sometimes an enemy
Much has been presented on orthodontic treatment at the early age: however, little has been discussed about the amount and role of growth during the same age period. It is well known that important changes occur from birth to eight years of age followed by another important period from eight to twelve years of age. But how do boys differ from girls in Class II and Class III patients? What gains can be expected and when would early Class II treatment in girls and boys not be worthwhile? What gains can be expected and when would early Class III treatment in girls and boys not be worthwhile? This paper intends to help orthodo...

Pediatric Obstructive Sleep Apnea : Insights and Current Research
Obstructive sleep apnea (OSA) is a multifaceted sleep-disordered breathing with many associated symptoms and comorbidities. OSA is recognized as a universal health problem and imposes significant healthcare costs on societies in many countries. Medically, continuous positive airway pressure therapy is the golden standard of treatment, while dentally, oral appliances and maxillofacial surgery may also be used for treatment. As orthodontic treatment has become a means of medical care that affects not only the oral and maxillofacial regions but also quality of life, orthodontists are increasingly focusing their attention on O...
