To investigate the effect of the accessory maxillary ostium (AMO) on the variations of adjacent structures of the maxillary sinus. The computed tomography (CT) images of 400 patients were retrospectively evaluated.

Therefore, a consensus on nocturnal CCD usage is lacking.
Purpose: The purpose of this clinical study was to assess the effects of nocturnal denture usage on cardiorespiratory stability by using pulse oximetry (PO).

The aim of this study was to evaluate the clivus morphology, including fossa navicularis magna (FNM), canalis basilaris medianus (CBM), and craniopharyngeal canal (CC), on computed tomography (CT) images. This is a retrospective study. Faculty of Dentistry, Department of Dentomaxillofacial Radiology.

Materials And Methods: This study was designed to evaluate the CBCT images of 1000 patients. The prevalences of the pneumatizations by age, sex, locularity, and laterality were determined.
Objective: CBCT applications have received widespread acceptance in dentistry. CBCT scans provide three-dimensional information on anatomic structures and characteristics of pathologies, rather than the two-dimensional information obtained with the conventional techniques. The purpose of this study was to evaluate incidental findings in out-of-interest areas on CBCT images and to reveal their frequency and characteristics.

Objective: This study assessed the use of different voxel resolutions in a cone beam computed tomography (CBCT) unit for the detection of artificially induced periodontal bone defects created using burr, burr and chemicals, and only chemicals.
Study Design: Seven dry skulls were used in this study. In total, 65 dehiscence defects, 43 fenestration defects, and 76 control sites with no periodontal defects were examined.
Objective: To report the number and frequency of incidental findings (IFs) detected during magnetic resonance (MR) imaging screening of the temporomandibular joint (TMJ) and to define related diseases.
Methods: Bilateral TMJ MR images in the sagittal and coronal sections, from 518 patients with TMJ symptoms were evaluated retrospectively. Patients who were diagnosed with IFs were sent for consultation and clarification of the findings.
Few studies have evaluated the interaction between conventional complete dentures (CCD) and the respiratory system and the authors are unaware of any that evaluated the interaction between implant-retained overdentures (IROs) and the respiratory system. This clinical report documented the effects of wearing an IRO on the cardiorespiratory stability of an edentulous patient with obstructive sleep apnea (OSA). A 64-year-old woman was referred to the department of otolaryngology because of daytime sleepiness and morning headaches.

Few examples of non-syndromal multiple supernumerary teeth have been reported. The aim of this multi-centre study was to investigate the prevalence of supernumerary premolar teeth in non-syndromic patients and to investigate the association between the presence of supernumerary premolar teeth and malocclusion type in a Turkish population.

In this study, it was aimed to research the effects of desferroxamine (DFO) application on bone and bone graft healing due to the effects of osteoblast and osteoclast regulation and stimulation of angiogenesis.
Methods: Rat zygomatic arch critical-size bone defect model (5 mm) was used as the experimental model.
Background: The teeth with undiagnosed vertical root fractures (VRFs) are likely to receive endodontic treatment or retreatment, leading to frustration and inappropriate endodontic therapies. Moreover, many cases of VRFs cannot be diagnosed definitively until the extraction of tooth.
Objectives: This study aimed to assess the use of different voxel resolutions of two different cone beam computerized tomography (CBCT) units in the detection VRFs in vitro.
Objectives: This study aimed to compare the diagnostic accuracy of two different cone-beam computed tomography (CBCT) units with several intraoral radiography techniques for detecting horizontal root fractures.
Methods: The study material comprised 82 extracted human maxillary incisors without root fractures that had not undergone any root canal treatment. Root fractures were created in the horizontal plane in 31 teeth by a mechanical force using a hammer with the tooth placed on a soft foundation as described in a previous study.

Vascular tumors are the most common benign tumors of the head and neck in infancy and childhood. Vascular anomalies of the head and neck were divided into 2 categories including hemangiomas and vascular malformations. Oral and maxillofacial hemangiomas and vascular malformations are congenital lesions with various clinical characteristics, manifestations, indications, and possibilities for treatment.

Materials And Methods: Eighteen edentulous jaws were randomly scanned by a CT (CT group) or a CBCT scanner (CBCT group) and radiographic gray density was measured from the planned implants. A total of 108 implants were placed, and primary stability parameters were measured by insertion torque value (ITV) and resonance frequency analysis (RFA).
Background: To determine the prevalence of periapical lesions in root canal-treated teeth in a rural, male adult, Turkish population and to investigate the influence of the quality of root canal fillings on prevalence of periapical lesions.
Methods: The sample for this cross-sectional study consisted of 552 adult male patients, 18-32 years of age, presenting consecutively as new patients seeking routine dental care at the Dental Sciences of Gulhane Military Medicine, Ankara. The radiographs of the 1014 root canal-treated teeth were evaluated.
Florid cemento-osseous dysplasia (FCOD) has been described as a condition that characteristically affects the jaws of middle-aged black women. It usually exhibits as multiple radiopaque cemetum-like masses distributed throughout the jaws. Radiographically, FCOD appears as dense, lobulated masses, often symmetrically located in various regions of the jaws.
