Purpose: The aims of our study were to determine the changes in the pharyngeal airway after treating patients with Class III malocclusion who received double jaw surgery, to determine the hard tissue and soft tissue parameters and the hyoid bone and tongue positions after surgery, to determine the changes to compare the pretreatment and post-treatment measurements of the patients in the double jaw group with the measurements of the control group patients, and to evaluate postoperative patient satisfaction.
Materials And Methods: The study included thirty-two Class III adult patients that received double jaw surgery and twenty-five Class I patients. Cephalometric records were taken before treatment (T1) and after treatment (T2).
Purpose: The purpose of this study was to compare the accuracy of the planimetric methods on volume estimations by using cone beam computed tomography (CBCT).
Materials And Methods: Thirty-one prepared intraosseous bone defects from thirteen bovine femur condyles were scanned with CBCT. The defect volumes were estimated by point counting (PC), manual segmentation (MS) and semiautomatic segmentation (SAS) methods at 0.
Objectives: Temporomandibular osteoarthritis causes pain and loss of function. In advanced cases, it may also result in destruction of joint cartilage surfaces and bone structure.
Methods: This study was performed to examine the potential changes in the condylar trabecular bone structure in patients with temporomandibular osteoarthritis.
Purpose: The present study examined the formation and density of new bone after sinus membrane elevation, with and without bone grafting, and evaluated the bone formation at the apices of the implants with these 2 different maxillary sinus floor elevation techniques.
Materials And Methods: In a prospective randomized controlled study design, patients requiring reconstruction of their atrophic maxilla were included and divided randomly into grafted and nongrafted groups. Implants were inserted in each group by way of sinus membrane elevation.
Purpose: The aim of this study was to evaluate the radiopacity of eight contemporary luting cements using direct digital radiography.
Materials And Methods: Ten specimens, (5 mm diameter, 1 mm high) were prepared for each material tested (RelyX ARC, RelyX U100, RelyX Unicem, Nexus 2, Nexus 3, Metacem, Breeze, Adhesor zinc phosphate). The specimens were stored in a moist chamber at 37°C until completely set, then radiographed using a Kodak digital sensor and an aluminum step wedge with variable thicknesses (1 to 13 mm in 1-mm increments) used for reference.

Objective: To evaluate the applicability of Demirjian and Nolla methods for northeastern Turkish population.
Material And Method: A retrospective study was performed on panoramic radiographs of 673 subjects aged 5-15.9 years.
The purpose of this study was to investigate the possible effects of section thickness on volume estimations obtained by cone beam computed tomography. Intraosseal cavities representing bone defects on vestibular sides of the two dry sheep mandibles were scanned by a cone beam computed tomography system. Consecutive sections at 0.

Materials And Methods: This study consisted of conventional FRs and CBCT-constructed FRs obtained from 30 young adult patients. Twenty-three landmarks were identified on both types of cephalometric radiographs.
Objective: The aim was to determine the accuracy of volumetric analysis of the mandibular condyle using cone-beam computed tomography (CBCT).
Materials And Methods: Five dry mandibles containing 9 condyles were used. CBCT scans of the mandibles and an impression of each condylar area were taken.
Functional impairment of DNA damage response pathways leads to increased genomic instability. Here we describe the centrosomal protein CEP152 as a new regulator of genomic integrity and cellular response to DNA damage. Using homozygosity mapping and exome sequencing, we identified CEP152 mutations in Seckel syndrome and showed that impaired CEP152 function leads to accumulation of genomic defects resulting from replicative stress through enhanced activation of ATM signaling and increased H2AX phosphorylation.

Methods: A total of 72 extracted human premolar and molar teeth were selected. Teeth were radiographed with conventional intraoral radiography, a storage phosphor plate system, and cone beam computed tomography and evaluated by two observers.
Inflammatory fibrous hyperplasia (epulis fissuratum) (IFH) and inflammatory papillary hyperplasia (IPH) are oral mucosal diseases caused by ill-fitting denture wearing. A study was carried out on a group of Turkish people consisted of 131 female and 39 male complete denture wearers (n= 170) distributed in two age groups (30-60 and 60-80 years old). The analysis of data collected from patients showed that while the incidence of IFH was higher in women than in men, the incidence of IPH was similar.

It is an important dental anomaly due to the possible pulpal involvement. DI can be detected clinically in a tooth presenting unusual crown morphology or having deep foramen coaceum.

This case report describes the presence of a foreign body (surgical needle) in the tonsillar area. The needle was overlooked during surgery. Following the surgery, the patient had no pain or other complaints related to the surgical site.
View Article and Find Full Text PDFOssifying fibroma is a benign fibro-osseous lesion of the jaw containing varying amounts of calcified deposits such as bone, cementum or both. This type of lesion is referred to as dysplastic or neoplastic in nature. In 2000, a 52-year-old male patient was referred to our clinic complaining of a giant swelling in the mandibular premolar-molar region.
