A controlled study of the functional and morphological characteristics of malocclusion in prematurely born subjects with low birth weight.

Background/objectives: Prematurely born children show significant delay in many areas of physical development, including the orofacial structures. The aim of the present study was to evaluate the influence of premature birth on the prevalence of functional and morphological characteristics of malocclusion in the deciduous dentition phase, considering also confounding variables, such as type of feeding and oral habits.

Material/methods: Through questionnaires and clinical examinations of 80 prematurely born subjects (42 females, 38 males, aged 24.

Three-dimensional assessment of palatal change in a controlled study of unilateral posterior crossbite correction in the primary dentition.

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.

The association of tongue posture with the dentoalveolar maxillary and mandibular morphology in Class III malocclusion: a controlled study.

The aim of the present study was to evaluate the association of tongue posture with the dentoalveolar maxillary and mandibular morphology in a group of Class III subjects in comparison to a group of Class I subjects. Twenty Class III subjects (9 males, 11 females, 19.2 ± 4.

Places in the dental arch that show a greater variability in tooth number, shape and position--a prevalence study.

Objective: The aim of this study was to assess the frequency of variations in tooth number, shape and position in the dental arch to determine if there are parts of the dental arch that show a higher prevalence of tooth variability.

Design: 198 randomly selected Caucasian subjects (93 females, 105 males) aged between 10.0 and 24.

Overjet as a predictor of sagittal skeletal relationships.

Skeletal relationships in the sagittal plane do not always correspond with dental relationships. The aim of this study was to determine in which type of malocclusion the correlation between overjet and skeletal sagittal parameters assessed by lateral cephalogram analysis is the highest. The extent to which overjet can predict skeletal relationships in the sagittal plane was also assessed.

Follow-up study of functional and morphological malocclusion trait changes from 3 to 12 years of age.

The aim of this study was to evaluate morphological and functional malocclusion trait changes in 3- to 12-year-old children and to determine whether such functional traits at the 3, 4, and 5 years of age correlated with malocclusion severity score at 12 years of age. Two hundred and sixty-seven children (132 boys, 135 girls) were randomly selected for a follow-up study from a previous cohort of 560 subjects. Functional and morphological traits were clinically assessed.

Intra- and inter-examiner reliability of intraoral malocclusion assessment.

Malocclusion assessment methods are based on measurements of study casts, which requires that impressions be taken. In addition to being costly and time consuming, this process can be unpleasant for children. Therefore, the aim of this study was to evaluate intra- and inter-examiner reliability of intraoral score measurements to determine malocclusion severity in the permanent dentition.

The influence of incompetent lip seal on the growth and development of craniofacial complex.

Abnormal orofacial functions in the period of growth and development can cause morphological anomalies of the craniofacial complex. The aim of this study was to determine the correlation between open mouth posture and morphology of craniofacial complex. The shape, size and relationships of skeletal parts of craniofacial complex were determined by analysis of lateral cephalograms in the sample of 84 children--45 girls and 39 boys (aged 8.

Cephalometric standards for Slovenians in the mixed dentition period.

The aim of this study was to develop standard cephalometric values for Slovenians in the period of the mixed dentition. Eighty-eight children were included in the study (46 girls and 42 boys, mean age 9.31 +/- 1.

Comparison of intra-oral and study cast measurements in the assessment of malocclusion.

Malocclusion assessment methods are based on registrations and measurements made on study casts, which requires that impressions be taken. In addition to being costly and time-consuming, this process can be unpleasant for very young children. Therefore, the aim of this study was to evaluate the reliability of intra-oral measurements that compute a malocclusion index score to determine malocclusion severity in the mixed dentition.
