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
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
Introduction: The aim of this study was to determine the peri-miniscrew implant crevicular fluid receptor
activator of nuclear factor-lB ligand (RANKL) and osteoprotegerin (OPG) levels around loaded and unloaded
miniscrew implants at different time intervals. Methods: Twenty loaded and 16 unloaded miniscrew implants
were included in this study. All miniscrew implants were placed bilaterally between the maxillary second premolars
and first molars as anchorage units for canine distalization. Peri-miniscrew implant crevicular fluid was taken
from the mesiobuccal aspects of the loaded and unl ...Daha fazlası
This in vitro study was to evaluate the erosive potential of four soft drinks at different times on bovine teeth by profilometry. Bovine incisors buccal side was sectioned with a diamond saw and a total of 100 enamel blocks were prepared (8 × 4 × 0.5 mm). Five specimens each were exposed to 60 ml of soft drinks (Sprite, Coca Cola, Cappy-orange and Ayran) for 15, 30, 60, 120 and 180 minutes in a continuously vibrating soft drinks bath in a beaker at room temperature. Surface loss of the specimens was determined with a profilometry. The data were analyzed by two-way analysis of variance and Tuke ...Daha fazlası
Ehlers Danlos Syndrome (EDS) is a connective tissue disease that has effect on the structure and function of collagen. Collagen is a fibrous protein that is one of the main building structures of connective tissues such as skin, tendon, bone and cartilage. Connective tissue requires all type of collagen to function correctly.
People with EDS may show symptoms such as skin hyperelasticity, joint hypermobility, increased tendency to bruise and abnormal scarring. Dental findings have been reported with some types of EDS. This case report describes the dental findings of a patient (10, c?) who ...Daha fazlası
Objective –The aim of this study was to evaluate the effects of local resveratrol
(RSVL) administration on bone formation in response to expansion of the interpremaxillary
suture, in rats.
Material and Methods – Twenty 50- to 60-day-old male Wistar rats were separated
into two equal groups. Both groups were subjected to expansion, and 30 cN of force
was applied to the maxillary incisors with helical-spring. Twenty-four hours after
appliance placement, single-dose 10 lmol ⁄ kg RSVL in the dimethylsulfoxide
(DMSO) was injected to the inter-premaxillary suture in the experimental group. In ...Daha fazlası
Objective: The purpose of this retrospective radiographic study was to determine the reliability and reproducibility of skeletal and
dental measurements of lateral cephalograms created from a computerised tomography (CT) scan compared with conventional
and digital lateral cephalograms.
Methods: CT and conventional lateral cephalograms of the same patients were obtained from university archives. The lateral
cephalometric radiographs of 30 patients were manually traced. The radiographs were subsequently scanned and traced using
Dolphin Imaging software version 11 (Dolphin Imaging, Chatswort ...Daha fazlası
