Proximity of healthy posterior teeth to the maxillary sinus floor in relation to mucosal thickening: a CBCT study.

Objectives: To evaluate the relationship between proximity of the root apices of healthy maxillary posterior teeth to the maxillary sinus floor (MSF) and mucosal thickening (MT) of the MSF using cone beam computed tomography (CBCT).

Methods: Eighty-four CBCT images obtained from the patients, aged between 20 and 70 years with healthy and fully dentate maxillary posterior sextants, were included. The anatomical relationship between root apices of maxillary posterior teeth and MSF, was evaluated: (Type 1: no contact, Type 2: at least one root apex in contact, Type 3: at least one root apex protruding into MSF).

Perceived sources and levels of stress, general self-efficacy and coping strategies in clinical dental students.

The aims of this study were to identify sources of stress among clinical students and to evaluate the students' perceived levels of stress, general self-efficacy and effective coping strategies in a private dental school environment. The study group consisted of 130 undergraduate clinical dental students in a Turkish private dental school, during the academic year 2014-2015. The students were surveyed using modified version of the dental environment stress (DES) survey, the perceived stress scale, the general self-efficacy scale (G-SES) and the brief coping scale.

Evaluation of morphology of the nasopalatine canal using cone-beam computed tomography in a subgroup of Turkish adult population.

Purpose: The aim of the study was to evaluate the anatomy and morphology of the nasopalatine canal (NPC) using cone-beam computed tomography (CBCT) and to determine variations of the NPC in relation to age, gender, and status of edentulism of anterior maxilla.

Methods: Patients scheduled for CBCT imaging for further radiographic evaluation of the maxilla with various reasons were consecutively enrolled in this study. Reformatted sagittal and coronal slices were analyzed with regard to dimensions and anatomic characteristics of the NPC.

Ethical decision making in dental education: a preliminary study.

Background: In terms of ethical decision making, every clinical case, when seen as an ethical problem, may be analyzed by means of four topics: medical indications, patient preferences, quality of life, contextual features. The aim of this study was to compare the performance of 4th year dental students on Ethical Decision Making before and after a course on ethics.

Methods: Fourth year dental students (n = 37) from academic year 2013-2014 participated in the study.

Evaluation of pneumatization in the articular eminence and roof of the glenoid fossa with cone-beam computed tomography.

Background: Detection of air cavities, so called pneumatizations, nearby to the temporomandibular joint (TMJ) area is important, as they represent sites of minimal resistance and facilitate the spread of various pathologies into the joint as inflammation, tumor or fractures and serve as a possible complicating factor in TMJ surgery.

Aims: To determine the prevalence of pneumatization of the articular eminence (PAT) and roof of the glenoid fossa (PRGF) using cone-beam computed tomography (CBCT).

Study Design: Cross-sectional study.

Comparison of case-based and lecture-based learning in dental education using the SOLO taxonomy.

The aim of this study was to compare the impact of case-based learning (CBL) and lecture-based learning (LBL) on fourth-year dental students' clinical decision making by using the Structure of Observed Learning Outcome (SOLO) taxonomy. Participants in the study were fourth-year dental students (n=55) in academic year 2012-13 taught in a large-group LBL context and fourth-year dental students (n=54) in academic year 2013-14 taught with the CBL methodology; both took place in the oral diseases course at Yeditepe University Faculty of Dentistry, Istanbul, Turkey. All eligible students participated, for a 100 percent response rate.

Articular eminence inclination, height, and condyle morphology on cone beam computed tomography.

Aim: The aim of the present study was to examine the relationship between articular eminence inclination, height, and thickness of the roof of the glenoid fossa (RGF) according to age and gender and to assess condyle morphology including incidental findings of osseous characteristics associated with osteoarthritis (OA) of the temporomandibular joint (TMJ) using cone beam computed tomography (CBCT).

Materials And Methods: CBCT images of 105 patients were evaluated retrospectively. For articular eminence inclination and height, axial views on which the condylar processes were seen with their widest mediolateral extent being used as a reference view for secondary reconstruction.

Three cases of elongated mandibular coronoid process with different presentations.

Abnormal elongation of the mandibular coronoid process is rare and its etiology is not yet elucidated. The aim of this report is to demonstrate and discuss the relationship between elongated mandibular coronoid process and limitation of mouth opening with cone beam computed tomography. Although the clinical characteristic of elongation of the coronoid process is mandibular limitation, in this report, one case had problem with mouth opening.

In Vitro Detection of Dental Root Fractures with Cone Beam Computed Tomography (CBCT).

Background: Since the diagnosis of non-displaced longitudinal fractures present difficulties for the dentist, three-dimensional evaluation is necessary.

Objectives: The aim of this study is to demonstrate the accuracy of cone beam computed tomography (CBCT) in detecting dental root fractures in vitro.

Materials And Methods: An in vitro model consisting of 210 recently extracted human mandibular teeth was used.

Measurements of the foramen magnum and mandible in relation to sex using CBCT.

The purpose of this study was to evaluate pre-existing CBCT images of a large sample of adult females and males to provide data on foramen magnum and mandibular measures of sexual dimorphism for use as a reference sample in cases of establishing identity in unknown fragmentary skulls. The study group consisted of 161 adult patients. 3D images of the patients were assessed retrospectively.

Evaluation of the posterior superior alveolar artery and the maxillary sinus with CBCT.

Assessment of the maxillary sinus anatomy before sinus augmentation is important for avoiding surgical complications, because of the close anatomical relationship between the posterior maxillary teeth and the maxillary sinus. The posterior superior alveolar artery (PSAA) is the branch of the maxillary artery that supplies the lateral sinus wall and overlying membrane. We evaluated the location of the PSAA and its relationship to the alveolar ridge and maxillary sinus using cone beam computed tomography (CBCT).

Assessment of the stylohyoid complex with cone beam computed tomography.

Background: Orientation of the stylohyoid complex (SHC) may be important for evaluation of the patient with orofacial pain or dysphagia.

Objectives: Our purpose was to assess the length and angulations of SHC using cone beam computed tomography (CBCT).

Patients And Methods: In this study, 3D images provided by CBCT of 69 patients (36 females, 33 males, age range 15-77 years) were retrospectively evaluated.

Assessment of root canal treatment outcomes performed by Turkish dental students: results after two years.

The aim of this study was to evaluate radiographically the periapical status and technical standard of root canal therapies performed by a group of undergraduate dental students in Turkey two years following completion of the treatments. A random sample of 264 patients who received root canal treatment from undergraduate students at the Yeditepe University Faculty of Dentistry in 2009 were recalled after two years.

Detection of artificial occlusal caries in a phosphor imaging plate system with two types of LCD monitors versus three different films.

The aim of this study was to determine diagnostic performance of a storage phosphor plate system Digora Optime (Soredex, Helsinki, Finland) with two types of LCD monitor in the detection of artificial caries when compared to Ultraspeed (D), Ektaspeed Plus (E), and Insight (F) radiographic films. Seventy extracted human molars-with artificial caries-were radiographed under identical standardized conditions using (1) a storage phosphor plate system Digora (Soredex, Helsinki, Finland), (2) Insight, (3) Ektaspeed Plus, and (4) Ultraspeed (Carestream Health Inc, Rochester, NY). All digital images and radiographs were examined by three observers for the presence or absence of artificial caries using a five-point confidence scale.
