Studies concerning the prevalence of extractions prior to orthodontic treatment have been limited in scope. This quasi-experimental analysis from secondary data explores patient and provider variables as they relate to extractions prior to comprehensive orthodontic therapy in the mixed dentition. This national database contains 38,529 children who had at least one comprehensive orthodontic (mix...

The disturbances of orofacial functions lead to abnormal growth and development of the orofacial complex. The aim of the study was to determine the prevalence of incompetent lip seal and respiration disturbance, and to improve the understanding of correlation between incompetent lip seal and morphological malocclusions. In the sample of 84 children (45 girls and 39 boys, aged 8.96 +/- 0.66 year...

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 ...

BACKGROUND Oral health is an important component of general health and is associated with the development of a healthy personality. The malocclusion has been shown to affects oral health, leads to increased prevalence of dental caries and may result in temporo-mandibular joint disorders. Hence, the present study was conducted to evaluate the malocclusion in subjects reporting for orthodontic tr...

AIM The purpose of this case report is the concurrent evaluation of the masticatory pattern and the electromyographic activity, recorded during mastication, before and after therapy of deep bite malocclusion. CASE REPORT An 11-year-old boy, affected by deep bite (overbite = 5 mm) was treated by the use of a functional appliance (Function Generating Bite for Deep bite correction = FGB-D). Mand...

Introduction: The malocclusions are among the main buccal health problems all over the world, together with dental cavity and periodontal disease. Several indexes are being used for malocclusion registration. The present study verified the prevalence of this condition, using the Angle classification and the Dental Aesthetic Index (DAI), the severity and the necessity of orthodontic treatment re...

The treatment of class II malocclusion during adolescence is an important challenge for orthodontists, moreover, if there are other growth factors that hinder the reaching of a normal occlusion. Maxillary molar distalization is an orthodontic treatment method that has obtained an important diffusion since last years for correcting pure dental Class II malocclusion. In the past, several applianc...

INTRODUCTION In this study, we investigated tooth-wear patterns in adolescents with either normal occlusion or Class II Division 2 malocclusion. METHODS The sample consisted of dental casts from 165 subjects that were divided into 2 groups: 115 normal occlusion subjects (mean age, 14.3 years) and 50 complete Class II Division 2 subjects (mean age, 13.9 years). Dental wear was assessed by usin...

Background: Hypodontia is one of the frequently observed dental anomalies in which dentofacial esthetics, phonetics, mastication, self-esteem and quality life can be adversely affected. Awareness disproportionate tooth number important must considered by orthodontists while making treatment plans to achieve proper occlusion, overbite, overjet, order restrain oral health deterioration. The aim t...

The aim of this longitudinal study was to compare the prevalence of malocclusion at age three and seven years in a sample of children, exploring the hypothesis that prevalence of malocclusion is higher at 3 than at 7 years of age and may be influenced by sucking habits. The study sample comprised 386 children (199 girls and 187 boys), aged 3 years at study start, sourced from three Public Denta...
