OBJECTIVE The aim of this study was to assess the existence of 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 17 ...

OBJECTIVE To evaluate the personality and psychosocial status of adult malocclusion patients through the Eysenck Personality Questionnaire (EPQ) and the Symptom Checklist 90 (SCL-90). METHODS The EPQ and the SCL-90 were administered to 348 adult respondents with Angle's Class I, II, III malocclusion and normal occlusion.

OBJECTIVES The objective of this study was to describe the prevalence of malocclusion in a population of Central Anatolian adolescents in relation to gender. METHODS The sample comprised 2329 teenagers (1125 boys and 1204 girls), aged between 12 and 17 years (mean age: 14.6 yrs). Occlusal anteroposterior relationships were assessed using the Angle classification. Other variables examined were...

In Class II malocclusion, a variety of treatment modalities have been presented in the literature. The camouflage orthodontic is a treatment alternative, involving extraction of premolars. In the absence of an important mandibular crowding, the interdental relations can be obtained by numerical reduction in the upper arch, resulting in a Class II molar and a Class I canine relationship. It is i...

BACKGROUND AND AIM: Malocclusions are major traits whose prevalence should be noticed, by gender, among high school students to program oral health status in a society and clarify the needs and demands of this orthodontic field. METHODS: In a cross-sectional population-based study, using a stratified random cluster sampling design, a sample of 1338 students of Shiraz, aged 14-18 years from 15 h...

This paper describes the orthodontic treatment of two cases that were successfully entered for the 2009 MOrth Cases Prize. The first case describes the treatment of a class II division 1 malocclusion with increased vertical proportions that was treated with upper and lower self-ligating appliances and headgear for anchorage support. The second case describes the use of a Clark Twin-Block applia...
