Cone-beam computed tomography assessment of mandibular asymmetry in unilateral cleft lip and palate patients

İLKNUR VELİ

Objective: To determine whether there is any difference between the cleft and non-cleft sides of the mandible in unilateral cleft lip and palate (UCLP) patients, or the right and left sides in control patients; and to determine if there is any difference between the mandibular asymmetry of UCLP patients and that of control patients. Methods: We examined cone-beam computed tomography (CBCT) scans of 15 patients with UCLP and 15 age- and gender-matched control patients. We evaluated 8 linear, 3 surface, and 3 volumetric measurements and compared the cleft/non-cleft sides of UCLP patients an ...Daha fazlası

Effects of demineralizaton-inhibition procedures on the bond strength of brackets bonded to demineralized enamel surface

TANCAN UYSAL

Objective: To study and compare the effects of different demineralizationinhibition methods on the shear bond strength (SBS) and fracture mode of an adhesive used to bond orthodontic brackets to demineralized enamel surfaces. Methods: Eighty freshly extracted, human maxillary premolars were divided into 4 equal groups and demineralized over the course of 21 days. Brackets were bonded to the demineralized enamel of teeth in Group 1. In Group 2, bonding was performed following resin infi ltration (ICON®, DMG, Hamburg, Germany). Before bonding, pre-treatment with acidulated phosphate fluor ...Daha fazlası

Dental and Alveolar Arch Widths in Normal Occlusion, Class II division 1 and Class II division 2

TANCAN UYSAL

The aim of this study was to compare the transverse dimensions of the dental arches and alveolar arches in the canine, premolar, and molar regions of Class II division 1 and Class II division 2 malocclusion groups with normal occlusion subjects. This study was performed using measurements on dental casts of 150 normal occlusion (mean age: 21.6 6 2.6 years), 106 Class II division 1 (mean age: 17.2 6 2.4 years), and 108 Class II division 2 (mean age: 18.5 6 2.9 years) malocclusion subjects. Independent-samples t-test was applied for comparisons of the groups. These findings indicate that t ...Daha fazlası

Ethnic differences in the soft tissue profiles of Turkish and European–American young adults with normal occlusions and well-balanced faces

ASLI BAYSAL | TANCAN UYSAL

The aim of this study was to evaluate soft tissue differences between Turkish and North American adults by comparing two sample populations with ideal occlusion and well-balanced faces. Lateral cephalometric radiographs of 117 Anatolian Turkish adults (65 female and 52 male, mean age: 23.9 ± 2.8 years) were compared with a sample of 116 adults of European–American ancestry (64 female and 52 male, mean age: 25.0 ± 6.8 years). The cephalometric analyses of Holdaway, Epker, and Legan and Burstone were performed using Dolphin Image Software 9.0. Thirty-two measurements (27 linear and 5 angular) we ...Daha fazlası

Relationship between odontogenic bacteremia and orthodontic stripping

TANCAN UYSAL

Introduction: The aim of this study was to evaluate the prevalence of bacteremia associated with an orthodontic stripping procedure. Methods: The study included 29 orthodontic patients (mean age, 18.2 6 3.4 years). We used a standardized stripping procedure: a perforated stripping disk with a contra-angle hand piece was used at a low speed (\15,000 rpm; 10 seconds) on the mandibular anterior teeth. Blood samples were collected by inserting a cannula into the left antecubital fossa. A baseline sample was taken before treatment, and a second sample was taken after the stripping procedure.

Dentoskeletal effects of Twin Block and Herbst appliances in patients with Class II division 1 mandibular retrognathy

ASLI BAYSAL

OBJECTIVE: The aim of this study is to evaluate dentoskeletal effects of Herbst and Twin Block (TB) appliance therapies in Skeletal Class II malocclusion. SUBJECTS AND METHODS: Herbst group consisted of 11 girls and 9 boys (mean age = 12.74±1.43 years), TB group comprised of 10 girls and 10 boys (mean age = 13.0±1.32 years), and control group included 9 girls and 11 boys (mean age = 12.17±1.47 years). Mean treatment/observation times were 15.81±5.96 months for Herbst, 16.20±7.54 months for TB, and 15.58±3.13 months for control group. Pre-treatment (T0) and post-treatment (T1) lateral cephal ...Daha fazlası

Dehiscence and fenestration in patients with different vertical growth patterns assessed with cone-beam computed tomography

İLKNUR VELİ | ŞÜKRÜ ENHOŞ

Objective: To test the null hypothesis that the presence of alveolar defects (dehiscence and fenestration) was not different among patients with different vertical growth patterns. Materials and Methods: A total of 1872 teeth in 26 hyper-divergent (mean age: 24.4 6 4.8 years), 27 hypo-divergent (mean age: 25.1 6 4.5 years), and 25 normo-divergent (mean age: 23.6 6 4.1 years) patients with no previous orthodontic treatment were evaluated using cone-beam computed tomography. Axial and cross-sectional views were evaluated with regard to whether dehiscence and/or fenestration on buccal and l ...Daha fazlası
