Cross-Sectional Study on Self-Perception of Dento-Facial Asymmetry.

: Facial symmetry is a key component of facial beauty and attractiveness. However, perfect symmetry is rare, and slight asymmetries, also known as natural asymmetries, are common and contribute to the uniqueness of each face. The perception of facial asymmetry varies among individuals and can be influenced by several factors.

Patient's satisfaction level with community pharmacies services in Romania: a questionnaire-based study.

Introduction: The patient satisfaction questionnaires in literature are according to the community pharmacies services in the authors' countries and not all have psychometric reports to support the results. We designed a questionnaire specific to the services of community pharmacies in Romania to evaluate the level of patient satisfaction.

Methods: We carried out a cross-sectional study on voluntary patients.

Investigations on the Degradation Behavior of Processed FeMnSi-xCu Shape Memory Alloys.

A new functional Fe-30Mn-5Si-xCu (x = 1.5 and 2 wt%) biomaterial was obtained from the levitation induction melting process and evaluated as a biodegradable material. The degradation characteristics were assessed in vitro using immersion tests in simulated body fluid (SBF) at 37 ± 1 °C, evaluating mass loss, pH variation that occurred in the solution, open circuit potential (OCP), linear and cyclic potentiometry (LP and CP), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and nano-FTIR.

Development and Functionalization of a Novel Chitosan-Based Nanosystem for Enhanced Drug Delivery.

Nowadays, infection diseases are one of the most significant threats to humans all around the world. An encouraging strategy for solving this issue and fighting resistant microorganisms is to develop drug carriers for a prolonged release of the antibiotic to the target site. The purpose of this work was to obtain metronidazole-encapsulated chitosan nanoparticles using an ion gelation route and to evaluate their properties.

Influence of Dynamic Strain Sweep on the Degradation Behavior of FeMnSi-Ag Shape Memory Alloys.

Iron-based SMAs can be used in the medical field for both their shape memory effect (SME) and biodegradability after a specific period, solving complicated chirurgical problems that are partially now addressed with shape-memory polymers or biodegradable polymers. Iron-based materials with (28-32 wt %) Mn and (4-6 wt %) Si with the addition of 1 and 2 wt % Ag were obtained using levitation induction melting equipment. Addition of silver to the FeMnSi alloy was proposed in order to enhance its antiseptic property.

Analysis of Degradation Products of Biodegradable ZnMgY Alloy.

Biodegradable metallic materials are increasingly gaining ground in medical applications. Zn-based alloys show a degradation rate between those recorded for Mg-based materials with the fastest degradation rate and Fe-based materials with the slowest degradation rate. From the perspective of medical complications, it is essential to understand the size and nature of the degradation products developed from biodegradable materials, as well as the stage at which these residues are eliminated from the body.

In-Vitro Analysis of FeMn-Si Smart Biodegradable Alloy.

Special materials are required in many applications to fulfill specific medical or industrial necessities. Biodegradable metallic materials present many attractive properties, especially mechanical ones correlated with good biocompatibility with vivant bodies. A biodegradable iron-based material was realized through electric arc-melting and induction furnace homogenization.

New Zn3Mg-xY Alloys: Characteristics, Microstructural Evolution and Corrosion Behavior.

Zinc biodegradable alloys attracted an increased interest in the last few years in the medical field among Mg and Fe-based materials. Knowing that the Mg element has a strengthening influence on Zn alloys, we analyze the effect of the third element, namely, Y with expected results in mechanical properties improvement. Ternary ZnMgY samples were obtained through induction melting in Argon atmosphere from high purity (Zn, Mg, and Y) materials and MgY (70/30 wt%) master alloys with different percentages of Y and keeping the same percentage of Mg (3 wt%).

The study of the Association of Decay Risk With Malocclusions in Mixed Dentition at Children From Northeast Romania. A Transversal Retrospective Study.

Aim: The purpose of this study was to investigate if high values of DMFT/dmft indices constitute risk factors for installation in various types of malocclusions in mixed dentition.

Material And Methods: The study consisted of 600 study-cast with mixed dentitions coming from the children in northeastern Romania. WHO (World Health Organization) dental caries criteria were applied to both groups.

CEPHALOMETRIC FEATURES OF CLASS III MALOCCLUSION.

Aim: The study aimed to identify quantitative and relational characteristics of bone, dental and soft tissue structures for Class III malocclusion, according to gender and age range.

Material And Methods: 60 conventional lateral cephalograms were divided into two groups according to ANB angle: the group of cases with skeletal Class III (n = 36) and a control group with skeletal Class I (n = 24). There were performed 53 digital cephalometric measurements according to Steiner, Tweed and Jarabak analyzes.

RISK FACTORS AND PREDICTORS OF CROSSBITE AT CHILDREN.

Aim: was to determine the etiological risk factors and predictors of crossbite' treatment at children.

Material And Methods: 270 cases with crossbites and 255 controls with other malocclusions were uniformly evaluated. The crossbites cases were divided in group I (anterior crossbite), group II (posterior crossbite) and group III (anterior and posterior crossbites) and were compared between them per Angle Class malocclusions, dysfunctional and dental causes, associations with other discrepancies, as well by need and types of treatment.

Craniofacial morphological changes of familial bilateral hypodontia of maxillary premolars.

The hypodontia of a permanent tooth from a dental group represents a normal evolution in human dentition morphology. Nevertheless, the hypodontia of two teeth within a dental group is a rare developmental anomaly when not associated to a systemic syndrome. The aim of this study was to report two rare cases of four maxillary premolars hypodontia, not including the third molar, of two white women from the same family.

Surgical-orthodontic treatment of malocclusions through Begg technique.

Aim: To assess the effectiveness and quality of surgical-orthodontic treatment outcomes through Begg technique in patients with malocclusions.

Material And Methods: Of a total of 117 patients referred to the Orthodontics Clinic lasi, 16 patients with malocclusions (7 boys and 9 girls) were selected according to certain criteria and received surgical and orthodontic treatment through Begg technique. The outcomes were assessed clinically and radiological.

Surface characteristics of retrieved coated and nickel-titanium orthodontic archwires.

Objective: The purpose of this study was to investigate the effects of oral fluids and archwire-bracket friction on the surface characteristics of NiTi alloy orthodontic archwires with/without aesthetic coating, in vivo for 2-3 months.
