The aim of this study was to quantify the palatal change in three groups of children: children with a unilateral posterior crossbite (TCB) who were treated, children with untreated unilateral posterior crossbite (UCB), and children without a crossbite (NCB). Study casts of 60 Caucasian children in the primary dentition (20 TCB, 20 UCB, and 20 NCB), aged 5.4 ± 0.7 years, were collected at baseli...

This study sets out to examine the prevalence of malocclusion and habits in a group of children with cerebral palsy and to compare it with a control group of healthy children. The presence of an anterior open bite was statistically significantly higher in the cerebral palsied group. The presence of aposterior crossbite was not significantly different between the examined groups, as was the case...

AIM Aim of the present study was to evaluate existing correlations between oral breathing and dental malocclusions. METHODS The study was conducted on a paediatric group of 71 oral breathers selected at the Allergology and Paediatric Immunology Department of Umberto I General Hospital, University of Rome "La Sapienza" (Italy). The children were selected based on inclusion/exclusion criteria. ...

The objective of this study was to evaluate the impact of malocclusion on the quality of life (QOL) of adolescents in Brazil. We carried out a cross-sectional study in a sample population of 1015 schoolchildren aged 12 to 15 years from São Luís, Maranhão, Brazil. The explanatory variable was malocclusion, evaluated on the basis of the normative need or the adolescent's self-perceived need for d...

Anterior crossbite is one of the most common forms of malocclusion in sagittal relationship of maxilla and mandible. If not corrected at the earliest, it will cause restriction of normal growth and development of both the jaws. The incidence of anterior crossbite is 4 to 5% in primary dentition. Self-correction may occur at the transient dentition or permanent dentition stage, but treating it s...

The aim of this study was to assess the orthodontic treatment effects on unilateral posterior crossbite in the primary and early mixed dentition by systematically reviewing the literature. A literature search was performed by applying the Medline database (Entrez PubMed) and covering the period from January 1966 to October 2002. The inclusion criteria were primary and early mixed dentition with...

AIM The purpose of this study was to evaluate the effectiveness of Haas RPE anchored on deciduous teeth in the early mixed dentition, for inducing the spontaneous correction of permanent incisor's crossbite, without compliance, without post bite-plane and no involvement of the permanent teeth. MATERIALS AND METHODS The sample group comprised 50 consecutive patients (mean age 8y 5m, SD 2y 1m),...

INTRODUCTION Incorrect tongue posture on the mouth floor is considered an important factor in the etiology of unilateral posterior crossbite. The aim of this study was to objectively assess tongue posture in children with unilateral posterior crossbite and those with normal deciduous dentition by using 3-dimensional (3D) ultrasonography. METHODS First, referential 3D ultrasound images for dif...

OBJECTIVE The aim of this retrospective study was to compare the longitudinal stability of two types of posterior crossbite correction: rapid maxillary expansion (RME) and slow maxillary expansion (SME). METHODS Study casts of 90 adolescent patients were assessed for interdental width changes at three different periods: pretreatment (T1), post-treatment (T2) and at least, five years post-rete...

The aim of this case report was to present the treatment of a 14-year-old patient with anterior crossbite with idiopathic root resorption. A 14-year-old female patient referred to our clinic because of the presence of crossbite on the maxillary central incisor. The smile esthetics were compromised because of the crossbite of the maxillary right central incisor. Intraorally, the patient had an A...
