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

Influence of Pre-Orthodontic Trainer treatment on the perioral and masticatory muscles in patients with Class II division 1 malocclusion

TANCAN UYSAL |

The aim of this follow-up study was to evaluate the effects of Pre-Orthodontic Trainer (POT) appliance on the anterior temporal, mental, orbicularis oris, and masseter muscles through electromyography (EMG) evaluations in subjects with Class II division 1 malocclusion and incompetent lips. Twenty patients (mean age: 9.8 ± 2.2 years) with a Class II division 1 malocclusion were treated with POT (Myofunctional Research Co., Queensland, Australia). A group of 15 subjects (mean age: 9.2 ± 0.9 years) with untreated Class II division 1 malocclusions was used as a control. EMG recordings of treatment ...Daha fazlası

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

An In Vitro Comparison of Different Diagnostic Methods in Detection of Residual Dentinal Caries

EBRU KÜÇÜKYILMAZ

The aim of this study was to investigate the efficiency of different diagnostic methods in detection of residual dentinal caries in excavated cavities. Fifty extracted molar with deep dentinal carious lesions were excavated using a slow-speed handpiece. All cavities were assessed by laser fluorescence(LF) device, electronic caries monitor(ECM), and caries detector dye(CDD) by three independent observers blindly. The measurements were repeated after two weeks. Specimens containing dentin slices 150 μm in thickness were prepared for histological analyses. The existence and absence of car ...Daha fazlası

Effect of resveratrol on bone formation in the expanded inter-premaxillary suture: early bone changes

TANCAN UYSAL

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

Comparison of craniofacial morphology, head posture and hyoid bone position with different breathing patterns

TANCAN UYSAL

Objectives: The aim of this study was to evaluate differences in craniofacial morphology, head posture and hyoid bone position between mouth breathing (MB) and nasal breathing (NB) patients. Methods: Mouth breathing patients comprised 34 skeletal Class I subjects with a mean age of 12.8 ± 1.5 years (range: 12.0–15.2 years). Thirty-two subjects with skeletal Class I relationship were included in the NB group (mean 13.5 ±1.3 years; range: 12.2–14.8 years). Twenty-seven measurements (15 angular and 12 linear) were used for the craniofacial analysis. Additionally, 12 measurements were evalu ...Daha fazlası

OPG and RANKL levels around miniscrew implants during orthodontic tooth movement

İLKNUR VELİ | ŞÜKRÜ ENHOŞ

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

Low-shrinking composites. Are they reliable for bonding orthodontic retainers?

TANCAN UYSAL

To evaluate the shear bond strength (SBS), fracture mode, wire pull out (WPO) resistance and microleakage between low-shrinking and conventional composites used as a lingual retainer adhesive. Methods: A total of 120 human mandibular incisor teeth, extracted for periodontal reasons, were collected. Sixty of them were separated into two groups. To determine the SBS, either Transbond-LR (3M-Unitek) or Silorane (3M-Espe) was applied to the lingual surface of the teeth by packing the material into standard cylindrical plastic matrices (Ultradent) to simulate the lingual retainer bonding area.

Ethnic differences in dentofacial relationships of Turkish and Saudi young adults with normal occlusions and well-balanced faces

TANCAN UYSAL

Objectives: The aims of the present study were (1) to determine ethnic differences in craniofacial dimensions between Turkish and Saudi populations and (2) to identify possible gender differences between males and females, based on a sample of untreated young adult subjects with normal occlusions and well-balanced faces. Methods: In total, 163 cephalometric radiographs were traced and evaluated to compare untreated adults of Turkish and Saudi ethnicity. The Turkish group comprised 86 subjects; 45 females and 41 males. The Saudi group comprised 77 subjects; 39 females and 38 males. For st ...Daha fazlası

Açık apeksli dişlerde MTA fillapex'in apikal sızıntıya etkisinin değerlendirilmesi

MERVE AKÇAY

Amaç: Nekrotik pulpalı immatür dişlerde kök ucunun açık olması, kök kanal sisteminin geniş ve kök ucuna doğru genişleyerek sonlanması nedeniyle bu dişlerde endodontik tedavi ile etkili bir apikal tıkama oluşturulması oldukça zordur. Bu yüzden bu dişlerin endodontik tedavilerinde kullanılacak kök kanal dolgu sisteminin apikal tıkama özelliği önem kazanmaktadır. Çalışmamızda hazırlanan simule immatür dişlerde yeni üretilmiş MTA Fillapex kanal dolgu patının Güta-perka ile birlikte kullanımı ve oluşturduğu apikal tıkamanın etkinliği Güta-perka/AH Plus kanal dolgu sistemi ile karşılaştırılarak in v ...Daha fazlası
