Knowledge of parents about bruxism in their children

Ebru DELİKAN

Objective: Bruxism is a jaw muscle activity disorder characterized by clenching or grinding of the teeth and can be seen in both children and adults. The purpose of this study is to evaluate the parental knowledge about bruxism in children. Methods: A cross-sectional study was conducted with 265 parents whose children were attended at University of Mersin pediatric dentistry and oral and maxillofacial surgery clinics. Children’s ages varied from 6 months to 16 years old. A 20-questioned questionnaire was used to collect the data. IBM SPSS Statistics 22 for statistical analysis (SPSS IBM, Turke ...Daha fazlası

Farklı Polisaj İşlemleri Uygulanan Geçici Restorasyon Materyallerinin Yüzey Pürüzlülüklerinin Karşılaştırılması

Hasan Murat Aydoğdu

Amaç: Bu çalışmanın amacı üç farklı yöntemle yüzey bitirme ve polisaj işlemi uygulanan geçici restorasyon materyallerinin yüzey pürüzlülüklerinin karşılaştırılmasıdır. Gereç ve Yöntem: Self-cure bis akrilik rezin (n=30), self-cure PMMA (n=30) ve prefabrike PMMA Cad/Cam bloğu (n=30) olmak üzere üç farklı sabit geçici restorasyon materyali kullanılarak, 15x18mm boyutlarında ve 2mm kalınlığında örnekler oluşturuldu. Örnekler polimerizasyonun tamamlanması amacıyla distile su içinde 24 saat bekletildikten sonra mavi kuşak hard frezle 60 saniye kaba tesviye; 180 ve 600 grid zımparalar ile 30’ar sani ...Daha fazlası

Evaluation of styloid chain calcification related to temporomandibular joint disc displacement: a retrospective cohort study

KIŞ HATİCE CANSU

Objectives: The present study aimed to evaluate any relationship between elongated styloid process (ESP) and temporomandibular joint disc displacement (TMJD). Study design: A retrospective cohort study. Setting: Dentomaxillofacial Radiology division of Erciyes University Dental Hospital. Participants: Ninety-four temporomandibular joints (TMJs) of 47 patients were allocated in this study. Intervention-disease: Two experienced dentomaxillofacial radiologists have interpreted all CBCT and MR images. Patients who referred with TMJ disorders were classified according to temporomandibular joint's d ...Daha fazlası

The effect of in-office bleaching applications on the color and translucency of composite resins

Özcan KARATAŞ

Aim: The study aimed to evaluate the relationship between the caries frequency, which was determined using different caries indexes Objective: The aim of this study was to investigate the effect of in-office bleaching agents on the color and translucency of different resin composites. Materials and Methods: Twenty-four disk-shaped specimens with 1 mm thickness and 8 mm diameter were fabricated from five different resin composites. The specimens were then divided into three subgroups, two office bleaching groups (40% Opalescence Boost, 38% Whitesmile Power Whitening) and one control group (n=8) ...Daha fazlası

Comparison of translucency and flexural strength of fiber-reinforced composite resin materials

Özcan KARATAŞ

Aim: The purpose of this study was to compare translucency values and flexural strength of composite resin materials reinforced with two different fibers.Materials and Methods: In this study, two direct composites (Clearfil Majesty Esthetic and Posterior) and an indirect composite (Tescera) used with a non-fiber control group and two fiber-reinforced (EverStick glass fiber and Ribbond polyethylene fiber) composite groups. Thirty specimens were obtained from the entire composites with dimensions of 25×2×2mm3. Translucency parameter values of the specimens were obtained using a spectrophotometer ...Daha fazlası

An evaluation of surface roughness after staining of different composite resins using atomic force microscopy and a profilometer

Özcan KARATAŞ

Aim: The aim of this study was to compare the surface roughness of different composite resins using atomic force microscope (AFM) and a profilometer after storage in different solutions. Materials and methods: Eight different composite resins were used in this study. Twenty specimens of each composite resin material were prepared using a 2-mm thick and 8-mm diameter stainless steel mold. After the composites had been placed in the mold, they were polymerized with a LED curing unit. The surfaces of all specimens were polished using aluminum oxide discs, and the specimens were then divided into ...Daha fazlası

Evaluation of the peri-implant bone trabecular microstructure changes in short implants with fractal analysis

Hatice Cansu KIŞ

Backgrounds: This study aimed to evaluate the microstructural changes in the peri-implant bone in patients with short implants in terms of implant survival status by using fractal analysis measurements. Results: Dental panoramic radiographs (DPRs) of 67 patients were examined and included in this study. Fractal analysis and measurement of the crown-implant ratio were performed with ImageJ. The fractal analysis measurement was performed on the DPRs obtained at preoperative (FD0) and in the follow-up periods (after 2 ± 2 weeks (FD1), 2 months ± 2 weeks (FD2), 6 months ± 2 weeks (FD3), and 12 mon ...Daha fazlası

Evaluation of the Willems and Cameriere’s dental age estimation methods in Turkish children–A modified version of Cameriere’s method

Hatice Cansu KIŞ

The purpose of this study was to compare the accuracy of dental age estimation results obtained using the Willems and Cameriere methods in a large Turkish sample. A further aim was to adapt Cameriere’s regression equation to the Turkish population and to produce an updated regression model appropriate for Turkish children. Finally, we compare the results of the Cameriere and Willems methods. The study group was obtained from two dental radiology department archives. The total sample consisted of 1878 Turkish children (972 boys, 906 girls) aged between five and 15 years. Willems and Cameriere’s ...Daha fazlası

Management of ameloblastoma with different imaging modalities

KIŞ HATİCE CANSU

Ameloblastoma is a benign epithelial odontogenic tumour. Its exact etiology is still unknown. It develops from the remnants of the dental lamina and dental epithelium. It is most frequently observed in the angulus-ramus region of the mandible. The prognosis of ameloblastoma depends on the age of the patient, size and expansion of the tumour, the location of the lesion and histological type. Current diagnostic investigations include clinical examination, histological evaluation and many imaging techniques from conventional x-ray radiographs to Positron Emission Tomography-Computed Tomography (P ...Daha fazlası
