Objective: To test the hypotheses that (1) there is no difference in mandibular asymmetry between
the crossbite and normal side in a unilateral crossbite group (UCG) and between the right and left
sides in a bilateral crossbite group (BCG) and a control group (CG); and (2) there is no significant
difference in mandibular asymmetry among crossbite groups and control group.
Materials and Methods: The cone-beam computed tomography scans of three groups were
studied: (1) 15 patients (6 male, 9 female; mean age: 13.51 6 2.03 years) with unilateral posterior
crossbite; (2) 15 patients (8 male, ...Daha fazlası
Objective: To evaluate the changes in cortical bone thickness, alveolar bone
height, and the incidence of dehiscence and fenestration in the surrounding
alveolar bone of posterior teeth after rapid maxillary expansion (RME) treatment
using cone-beam computed tomography (CBCT). Methods: The CBCT records of
20 subjects (9 boys, mean age: 13.97 ± 1.17 years; 11 girls, mean age: 13.53 ±
2.12 year) that underwent RME were selected from the archives. CBCT scans had
been taken before (T1) and after (T2) the RME. Moreover, 10 of the subjects had
6-month retention (T3) records. We used th ...Daha fazlası
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
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
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
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
