A crossbite (CB) occurs in approximately 4–23 per cent of young children and may lead to mandibular facial asymmetry. Therefore, early intervention is often necessary create conditions for normal occlusal development. The aim this study was assess asymmetry palatal volume (pre- post-treatment) two groups children, one with a unilateral CB the other no (NCB). Thirty (13 males, 17 females, mean age 4.9 ± 0.98 years) 28 NCB (17 11 5.3 0.36 were included study. Those treated an intra-oral...

To use 3-dimensional (3D) facial averages to test the hypothesis that morphologies of 2 European white groups (Slovenia and Wales) have no differences.Fifty males 50 females from Wales 43 44 Slovenia were included in study. Subjects ranged 18 30 years age. Four subgroups formed: Slovenian (SM), (SF), Welsh (WM), (WF). 3D data acquired using a laser scanning system. An average face for each subgroup was obtained previously validated mathematical algorithm. Facial differences quantified after...

To evaluate palatal vault change in children and to assess the reliability of two parameters assessing growth modifications.A group 26 healthy white aged 5.3 ± 0.3 years (15 boys, 11 girls) were randomly selected. Impressions upper dental arches obtained at baseline 12, 18, 30 months follow-up. Three-dimensional digital images study casts using a laser scanning device. Palatal surface area volume measured on each time point. Effect size (ES) coefficients calculated for both as indices...

To assess the degree of facial asymmetry associated with subjects unilateral functional crossbite (CB) in primary, early/intermediate, and late mixed dentition phases comparison a group without CB.A 234 white subjects, 78 CB (42 girls 36 boys) 156 (73 83 boys), aged 3.9-11.9, grouped according to phase, were included. Three-dimensional laser scans subjects' faces used asymmetry. For each part face two-way multivariate analysis covariance was performed differences among an independent sample...

The aim of this study was to quantify the palatal change in three groups children: children with a unilateral posterior crossbite (TCB) who were treated, untreated (UCB), and without (NCB). Study casts 60 Caucasian primary dentition (20 TCB, 20 UCB, NCB), aged 5.4 ± 0.7 years, collected at baseline (T1) 1-year follow-up (T2). Both TCB UCB had midline deviation. group treated using cemented acrylic splint expander upper arch. scanned laser scanner surface area, volume, symmetry vault...

Occlusion is an important factor that affects chewing. Unilateral posterior crossbites (UPXBs) have been reported to be one of the most prevalent malocclusions in primary dentition and patients with UPXBs show abnormal condylar motion on crossbite side mediolateral direction during mastication. The aims this study were investigate characteristics common chewing cycles children UPXBs, when gum UPXB non-UPXB side, compare average pattern a group normal buccal relationship. Twenty (6 boys, mean...

Facial soft tissues changes during growth roughly tend to mimic the underlying hard tissues, but not completely. The aim of this mixed longitudinal study was assess facial among pre-pubertal and pubertal subjects without malocclusion using a non-invasive three-dimensional laser scanning system. Fifty-nine (30 females 29 males) aged at baseline 5.4–8.9 years with normal occlusion were clustered into younger, older pre-pubertal, groups according age absence/presence standing height spurt....

Orthodontic tooth movement (OTM) is a biological process that can influence the function of pulp, including its innervation. The excitability nerve fibres pulp may be altered by forces exerted on or reduced blood flow to pulp. aim this clinical study was evaluate sensitivity dental during levelling and phase space closure, assess role certain controlled risk factors.

During material treatment in dentistry particles of different size are released the air. To examine degree particle exposure, air scanning to dental employees was performed by Scanning Mobility Particle Sizer. The size, shape and chemical composition collected with a low-pressure impactor were determined electronic microscopy X-ray dispersive analysis. average concentrations nanoparticles during working periods clean laboratory (45,000-56,000 particles/cm3), an unclean (28,000-74,000 office...

Samples of Nitinol were oxidized using different procedures in order to improve their biocompatibility and prevent the release Ni. The evolution surface oxide films was monitored Auger electron spectroscopy (AES). only procedure that led formation nickel-free involved a pre-treatment with hydrogen plasma for 10 s followed by treatment composed 90% H2 10% O2.
