Influence of casein phosphopeptide-amorphous calcium phosphate on the surface topography and composition of nickel-titanium archwires during orthodontic treatment with fixed appliances.

Purpose: To investigate the surface topography and nickel content of nickel-titanium (NiTi) archwires exposed to either routine oral hygiene or a prophylactic regimen with casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) during orthodontic treatment.

Methods: This in vivo study involved 40 orthodontic patients with fixed appliances, who were randomly assigned to either a routine oral hygiene group or a CPP-ACP supplementary regimen group. Twenty new NiTi archwires served as controls.

The Participation of Pediatric Dentists in Oral Health Promotion and Education in Serbia.

Objectives: To identify the involvement of Serbian paediatric dentists in oral health promotion and education, and to propose further actions for the improvement of these activities.

Methods: This is an analysis of data collected by a cross-sectional, questionnaire-based survey of 445 dentists involved in the provision of dental health services to children at the primary healthcare level. We explored dentists' involvement in oral health education and promotion and the cooperation with other health professionals at the healthcare centre and the community level as well as their attitudes towards the importance of some factors influencing their work.

Meta-Analysis of In-Vitro Bonding of Glass-Ionomer Restorative Materials to Primary Teeth.

Restoration of primary teeth is among the main clinical applications of glass-ionomer cements (GIC). The aim of the study was to review and summarize existing evidence of bond strength of glass-ionomer (GI) restoratives to enamel and dentin of primary teeth. A literature search was performed in PubMed/Medline, Scopus, Web of Science, Cochrane, and Google Scholar databases to identify studies published until April 2021.

Dental Age Estimation According to European Formula and Willems Method: Comparison Between Children With and Without Cleft Lip and Palate.

Objective: To assess dental age and deviations of dental from chronological age according to the Willems and Cameriere methods (European formula) in patients with cleft lip and/or cleft palate (CL/P) and compare it with control group.

Design: Retrospective cross-sectional study.

Setting: Clinic of Orthodontics.

Bone microRNA-21 as surgical stress parameter is associated with third molar postoperative discomfort.

Objective: To evaluate an association between bone levels of inflammation/oxidative stress mediators and postoperative discomfort after third molar conventional or piezosurgery.

Material And Methods: Twenty-six subjects with bilaterally impacted mandibular third molars, who underwent either piezo or conventional surgery, were included in a split-mouth design study. MicroRNA-21 (miR-21) expression, interleukin-1 beta (IL-1β), and vascular endothelial growth factor (VEGF) proteins, as well as superoxide dismutase (SOD) activity in alveolar bone, were evaluated.

Differences in cytocompatibility, dynamics of the oxide layers' formation, and nickel release between superelastic and thermo-activated nickel-titanium archwires.

Superelastic (SE) and thermo-activated (TA) nickel-titanium (NiTi) archwires are used in everyday orthodontic practice, based on their acceptable biocompatibility and well-defined shape memory properties. However, the differences in their surface microstructure and cytotoxicity have not been clearly defined, and the standard cytotoxicity tests are too robust to detect small differences in the cytotoxicity of these alloys, all of which can lead to unexpected adverse reactions in some patients. Therefore, we tested the hypothesis that the differences in manufacture and microstructure of commercially available SE and TA archwires may influence their biocompatibility.

The correlation between pain perception among patients with six different orthodontic archwires and the degree of dental crowding.

Introduction: Forces generated in orthodontic treatment with fixed appliances create tension and compression zones in the periodontal ligament resulting in a painful experience for patients. In the first phase of orthodontic treatment, when leveling of teeth is needed, nickel-titanium (NiTi) archwires can be completely engaged in brackets, even in the cases of extreme crowding, exerting small forces. There is a great individual variation in the pain perception related to the application of orthodontic forces.

[Dentaoalveolar changes in young adult patients with class II/1 malocclusion treated with the herbst appliance and an activator].

Background/aim: Functional appliances can be used effectively in the treatment of skeletal Class II/1 malocclusions. The best treatment results are obtained during active period of facial growth when skeletal, as well as dentoalveolar, changes occur. In comparison with removable functional appliances, such as activator, that are effective only during adolescent period of growth, the Herbst fixed appliance is also successful at the end of the growth period.

[Orthodontic treatment of nongrowing patient with Class II Division 2 malocclusion by Herbst appliance].

Background: Inheritance is most casual etiological factor of Class II division 2 malocclusion. This kind of malocclusion is very difficult for treatment specially in older patients.

Case Report: In the female patient, 20 years old, at the beginning of the treatment at the School of Dentistry in Belgrade, lateral cephalogram showed skeletal and dentoalveolar Class II division 2 malocclusion.

Craniofacial complex specificities in five men with sex reversal syndrome.

In order to clarify the role of sex chromosome constitution in craniofacial growth control, we compared craniofacial morphology of men with sex reversal syndrome (46, XX) with the morphology of normal men, Klinefelter's syndrome and normal women, using cephalometric measurements. Due to physical resemblance between men with 46, XX karyotype and men with 47, XXY karyotype, cephalometric analysis comprised parametres which had already been found to be specific for Klinefelter's syndrome, i.e.
