This study aims to critically review the literature in respect to craniofacial bone abnormalities and malocclusion in sickle cell anemia individuals. The Bireme and Pubmed electronic databases were searched using the following keywords: malocclusion, maxillofacial abnormalities, and Angle Class I, Class II and lass III malocclusions combined with sickle cell anemia. The search was limited to pu...

This study assessed the malocclusion types, very severe crowding and need for serial extraction among a random sample of 7-9-year-old children in Shiraz, Islamic Republic of Iran. Of the 3776 children 30.6% had normal occlusion, 47.4% class I malocclusion, 13.7% class II division 1 malocclusion (male/female ratio 3:2), 1.0% class II division 2 malocclusion (male/female ratio 3:1) and 2.1% class...

Introduction: This study aims at examining the difference of pharyngeal airways in patients with different occlusion postures, hoping to im‌prove diagnostic methods and provide a stable treatment plan for orthodontic patients. Materials and Methods: The data were ga-thered through CBCT radiographies of patients from a specialized center for radiology. In each occlusion group according to the p...

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...

OBJECTIVE Treating Class II subdivision malocclusion with asymmetry has been a challenge for orthodontists because of the complicated characteristics of asymmetry. This study aimed to explore the characteristics of dental and skeletal asymmetry in Class II subdivision malocclusion, and to assess the relationship between the condyle-glenoid fossa and first molar. METHODS Cone-beam computed tom...

OBJECTIVE The objective of this study was to investigate the differences in masticatory efficiency among patients with different Angle's classes of malocclusion and to assess the correlation between masticatory efficiency and the occlusal contact area. METHODS The mixing ability index (MAI) was calculated for measuring masticatory efficiency of 61 adult patients according to Angle's classific...

OBJECTIVE The aim of this study was to clarify the morphological differences in the mandibular arches of Turkish and North American white subjects. METHODS The sample included 132 Turkish (34 Class I, 58 Class II, and 40 Class III) and 160 North American (60 Class I, 50 Class II, and 50 Class III) subjects. The most facial portion of 13 proximal contact areas was digitized from photocopied im...

This study evaluated the relationship among malocclusion, number of occlusal pairs, masticatory performance, masticatory time and masticatory ability in completely dentate subjects. Eighty healthy subjects (mean age = 19.40 ± 4.14 years) were grouped according to malocclusion diagnosis (n = 16): Class I, Class Class II-2, Class III and Normocclusion (control). Number of occlusal pairs was deter...

OBJECTIVES The aim of this study was to evaluate the association between tooth agenesis and skeletal malocclusions in Brazilian non-syndromic orthodontic patients. MATERIAL AND METHODS Pretreatment orthodontic records of 348 patients of both genders and with various skeletal malocclusions were examined. Tooth agenesis was evaluated in panoramic radiographs. Angular measurements were taken fro...
