The purpose of this study was to compare the short- and long-term changes in condylar position related glenoid fossa, skeletal occlusal stability after orthognathic surgery. All patients were assessed by cone-beam computed tomography images for rotational anteroposterior pre-surgery, post-surgery post-retention period. positions evaluated on three planes: axial, coronal sagittal. In measurements, there no significant difference between group group. After sagittal split ramus osteotomy...
To evaluate the alveolar bone loss around lower incisors incurred during surgical orthodontic treatment in individuals with mandibular prognathism.The samples consisted of 25 patients (13 men, 12 women; mean ages: 26.3 ± 2.7 years) treated jaw surgery and treatment. Lateral frontal cephalograms cone-beam computed tomography (CBCT) images were obtained before (T0) after presurgical (T1) debonding (T2). After measurement variables, repeated-measures analysis variance Bonferroni's multiple...
Orthodontic treatment involving the bonding of fixed appliances to tooth surfaces can cause white spot lesions (WSLs). WSLs increase likelihood cavity formation and hence require preservation prosthetic restoration. Therefore, prevention is greater importance than treatment. Application fluoride or use fluoride-containing mouthwash prevent WSLs, but this requires patient cooperation additional time cost. Bioactive glass containing 2.5% was synthesized mixed with orthodontic adhesive...
ABSTRACT Objective: To evaluate the effect of postoperative condylar axis changes on mandibular remodeling by comparing head in three-dimensional (3D) surface reconstructions before and after surgery skeletal Class III deformities (one-jaw [mandibular setback] or two-jaw surgery), also to determine relationship between inward rotation orthognathic surgery. Materials Methods: A retrospective analysis was conducted 30 patients with who had received Group 1 underwent one-jaw (10 men, five...
Three-dimensional evaluation of midfacial asymmetry in patients with nonsyndromic unilateral cleft lip and palate by cone-beam computed tomography Objective: To compare three-dimensionally the hard-and soft-tissue asymmetries between affected unaffected sides determine relationship hard tissue overlying soft complete (UCLP) conebeam (CBCT) analysis.Methods: The maxillofacial regions 26 adults (18 men, 8 women) UCLP were scanned CBCT reconstructed three-dimensional dental imaging.The...
To evaluate condylar head remodeling after mandibular set-back sagittal split ramus osteotomy (SSRO) with rigid fixation in skeletal class III deformities. The correlation between and axis changes was determined using cone-beam computed tomography (CBCT) superimposition.The CBCT data of 22 subjects (9 men 13 women) who had undergone SSRO were analyzed. Changes the measurements distribution signs evaluated by showed inward rotation axial angle; reduced heights on coronal planes; resorptive...
Dentin hypersensitivity (DH) is one of the most common clinical conditions usually associated with exposed dentinal surfaces. In this study, we identified effectiveness poly(amidoamine) (PAMAM) dendrimer-coated mesoporous bioactive glass nanoparticles (MBN) (PAMAM@MBN) on DH treatment, examining ion-releasing effect, dentin remineralization, and occluding effect tubules. We synthesized MBN PAMAM@MBN. After soaking each sample in simulated body fluid (SBF), observed effects remineralization...
The present study tested the shear bond strength (SBS) of orthodontic brackets bonded to teeth using flowable resins. A total 105 human were divided into seven groups. in each group tooth substrates a Transbond XT adhesive and six other different resins, respectively. Each resin was light-cured quartz-tungsten-halogen (QTH) light for 40 seconds. debonded mode universal testing machine. Tetric Flow Grandio showed slightly greater SBS values (13.0±1.8 12.2±1.2 MPa, respectively) than (12.1±1.2...
Human immunodeficiency virus type 1 (HIV-1) integrase is an essential enzyme in the life cycle of virus. It responsible for catalyzing insertion viral genome into host cell chromosome. This attractive target design a HIV antiviral drug, because has no human counterpart. In order to know interaction mode HIV- with its inhibitor, we investigated effect baicalein, on conformation HIV-1 catalytic domain [IN-(50-212/F185K)] using fluorescence and circular dichroism (CD) spectroscopy. We found...
Gaegurin 5 is a 24-residue, membrane-active antimicrobial peptide isolated from the skin of an Asian frog, Rana rugosa. We recently reported activities two novel undecapeptides derived inactive N-terminal fragment (residues 1-11) gaegurin (Won, et al. J. Biol. Chem. 2004, 279, 14784-14791). In present work, anticancer undecapeptide analogues were additionally identified. The relationships between their structural properties and biological assessed by characterizing fundamental determinant...
Comparison of masticatory efficiency according to Angle's classification malocclusionObjective: The objective this study was investigate the differences in among patients with different classes malocclusion and assess correlation between occlusal contact area.Methods: mixing ability index (MAI) calculated for measuring 61 adult classifications malocclusion.The included 25, 15, 21 Class I, II, III malocclusions, respectively.Silicone interocclusal recording material used measure area.Results:...
All orthodontic appliances are potentially cariogenic. The plaque around the appliance can make demineralization on tooth surface causing white spot lesion (WSL). most effective method to prevent WSL is Fluoride and gargling, but this requires patient cooperation, which consumes additional treatment time cost. As suggested in study, biomaterials like bioactive glass fluorinated graphite (FGt) having antibacterial anti-demineralization ability easy use clinic. To clinically bonding resins...

Materials Methods standard composite constructed from different females' intraoral extraoral photographs. Vertical were modified digitally 1‐mm increments, 5 mm upper lip...
In this study, we aimed to examine the relationship between chin deviation and positional morphological features of mandible determine factors that contributed in individuals with a unilateral cleft lip palate (UCLP).Cone-beam computed tomography (CBCT) images 28 adults UCLP were analyzed study. Segmented three-dimensional temporomandibular fossa reconstructed, angular, linear, volumetric parameters measured.For all individuals, was found deviate side by 1.59 mm. Moreover, among these only 7...
The purpose of this study was to investigate the isolation and characterization multipotent human periodontal ligament (PDL) stem cells assess their ability differentiate into bone, cartilage, adipose tissue.PDL were isolated from 7 extracted premolar teeth. Human PDL expanded in culture, stained using anti-CD29, -CD34, -CD44, -STRO-1 antibodies, sorted by fluorescent activated cell sorting (FACS). Gingival fibroblasts (GFs) served as a positive control. GFs cultured standard conditions...
