ii To my supportive parents, Scott and Julie iii ACKNOWLEDGMENTS I would like to thank Dr. Lina Moreno for all of her dedication and guidance with this research study. This project would not have been possible without her and the rest of my thesis committee, Drs. for giving me the opportunity to further my education and pursue a career in orthodontics. Finally, I would like to thank my wonderfu...

AIM The aim of this study was to assess the dynamic activity of the mandible by means of a computerised kinesiograph in Class II patients treated with orthodontic therapy and to compare the results of this group with those of a sample of untreated Class II patients. METHODS Twenty young adolescents who had undergone orthodontic treatment for correction of Class II malocclusion and twenty age ...

This case report highlights the treatment of a skeletal Class II malocclusion with pseudoanodontia that indicated clinical but not radiographic absence of teeth. A 21-year-old female patient presented with a skeletal Class II malocclusion with an orthognathic maxilla and a retrognathic mandible, with Angle’s Class I malocclusion with rotated maxillary and mandibular anteriors with fourteen impa...

BACKGROUND AND AIMS Malocclusion with its great hazardous effects seems to have become more prevalent in recent decades; therefore, the present study was carried out to assess the prevalence of different malocclusions among 13-15 year-old adolescents in Tabriz. MATERIALS AND METHODS The subjects in the present study consisted of 398 adolescents aged 13-15, who were randomly selected from 5 di...

AIM The purpose of this study was to investigate the prevalence of hyperopia and strabismus among a paediatric population with malocclusions. MATERIALS AND METHODS From a total of 322 consecutive patients observed at the department of Orthodontics and Gnathology, Dental Clinic, University of L'Aquila, 176 were selected for the study according to the exclusion criteria. Pretreatment diagnos...

It is not fully understood whether masticatory performance is compromised in individuals with the more common forms of malocclusion (i.e. Class I and Class II). The aim of this prospective investigation was to establish the relationships between masticatory performance, malocclusion (type and severity), age, body size and gender, in children and adolescents. A total of 335 individuals were exam...

OBJECTIVE The aim of this study was to assess the presence of oral myofunctional alterations before and after first premolar extraction in Class II/1 malocclusion patients that could endanger the long-term dental arch stability. MATERIAL AND METHODS The study was performed by means of morphological, functional and electromyographic analyses in 17 Class II/1 malocclusion patients (group T) and...

Objective: To verify the presence and degree of asymmetry of dental arches in Brazilian individuals with natural normal occlusion and Class II, Divisions 1 and 2 malocclusions. Methods: The study evaluated the symmetry of the maxillary and mandibular dental arches of 180 pairs of dental casts, divided into: Group I = 60 pairs of natural normal occlusion individuals; Group II = 60 pairs of Class...

INTRODUCTION α-Actinins are myofibril anchor proteins that influence the contractile properties of skeletal muscles. ACTN2 is expressed in slow type I and fast type II fibers, whereas ACTN3 is expressed only in fast fibers. ACTN3 homozygosity for the 577X stop codon (ie, changing 577RR to 577XX, the R577X polymorphism) results in the absence of α-actinin-3 in about 18% of Europeans, diminishes ...
