Dental radiographic changes in individuals with COVID-19: a controlled retrospective study.

Objective: The aim of this study is to compare the pre-COVID-19 and post-COVID-19 dental radiological findings of individuals with positive rRT-PCR test results and with healthy controls using the apical periodontitis grade scale (APGS), radiographic-based periodontal bone loss (R-PBL), and radiographic DMFT indices, and to investigate the relatively long-term dental effects of COVID-19.

Methods: This study included people who had two panoramic radiographs taken between 2018 and 2022. There are 52 patients with positive rRT-PCR tests in the study group.

Evaluation of ultrasonography as a diagnostic tool in the management of periapical cysts and granulomas: A clinical study.

Purpose: The aim of this study was, firstly, to determine the concordance of ultrasonographic and histopathological diagnoses in patients in whom apical resection was already indicated. Secondly, this study aimed to determine whether lesions were periapical granulomas or cysts, and to compare them after root canal treatment using ultrasonography and periapical radiographs.

Materials And Methods: In the first stage of the study, ultrasonographic and histopathologic diagnoses of 10 lesions were compared.

Fractal properties and radiomorphometric indices of the trabecular structure of the mandible in patients using systemic glucocorticoids.

Objectives: The aim of this study is to evaluate the mandibular trabecular and cortical bone structure of patients using systemic glucocorticoid (GC) and compare to control group with the fractal analysis (FA) and radiomorphometric indices.

Methods: Two researchers retrospectively investigated 192 dental panoramic radiographs to compare individuals using systemic GCs to healthy controls. FA was performed in 4 different regions; geometrical center of the mandibular ramus (ROI1), cancellous bone on supracortical mandibular angle area inferior to the mandibular canal (ROI2), cancellous bone on mesial to the mental foramen (ROI3), basal cortical bone extending mental foramen to the first molars' distal root in the mandibular corpus (ROI4).

The evaluation of agreement between high-frequency ultrasonography and research diagnostic criteria for the diagnosis of temporomandibular joint internal derangements.

Aim: The aim of this study is to compare the diagnosis of patients with temporomandibular joint (TMJ) internal derangements which had been diagnosed using Research Diagnostic Criteria/Temporomandibular Disorders (RDC/TMD) with the dynamic high resolution sonography findings.

Settings And Design: Axis I section of RDC/TMD form had been applied to participants. Participants were divided into three groups as healthy TMJ, disc displacement with reduction, and disc displacement without reduction.

Investigation of the effectiveness of CBCT and gray scale values in the differential diagnosis of apical cysts and granulomas.

Purpose: The aim of this study was to investigate the effectiveness of cone-beam CT (CBCT) findings and gray scale values (GSV) in the differential diagnosis of apical cysts and granulomas.

Methods: Two independent researchers retrospectively analyzed the CBCT images of 21 teeth and histopathologically diagnosed them as having radicular cysts or apical granulomas. In the CBCT images, apical lesions were evaluated and categorized according to 7 criteria.

The evaluation of lateral pterygoid signal intensity changes related to temporomandibular joint anterior disc displacement.

Objectives: The aim of this study was to evaluate lateral pterygoid muscle (LPM) signal intensity changes related to different degrees of disc status groups using magnetic resonance imaging (MRI).

Methods: Four groups were established according to disc displacement of examined temporomandibular joint (TMJ) and opposing TMJ. MRI scans were obtained with a 1.

Masseter muscle thickness and elasticity in periodontitis.

This study aimed to compare the thickness and elasticity of the masseter muscle between patients with gingivitis and patients with periodontitis. A total of 124 patients (63 gingivitis, 61 chronic periodontitis) were recruited at the start of the study, but only 84 patients were declared as final participants. Patients were divided into two groups: (1) patients suffering from gingivitis and (2) those with generalized chronic periodontitis.

Central giant cell granulomas of the jaws: retrospective radiographic analysis of 13 patients.

Objective: This study was performed to retrospectively analyse the imaging features of 13 patients with central giant cell granulomas (CGCGs) examined at a single institution.

Methods: The orthopantomography and cone beam computed tomography images of 13 patients histopathologically diagnosed with CGCGs were retrospectively analysed. Patients aged > 30 years underwent measurement of their calcium and parathyroid hormone levels.

Odontogenic tumors: a collaborative study of 218 cases diagnosed over 12 years and comprehensive review of the literature.

Objectives: The objective of this study was to analyze the frequency and distribution of odontogenic tumors (OTs) in the Cappadocia region of Turkey, and to compare the findings with those reported in the literature.

Study Design: The records of the Oral and Maxillofacial Surgery and Pathology Departments at Erciyes University, with histologic diagnosis of odontogenic tumors (based on the World Health Organization classification, 2005), over a 12-year period, were analyzed. The relative frequency of different types of tumors was also analyzed and compared with the literature.

Evaluation of the nasopalatine canal and variations with cone-beam computed tomography.

Purpose: Although nasopalatine canal (NPC) is one of the most important anatomical structures in premaxillary region, few documents are available with regard to anatomic variations, size, and morphology of NPC in the literature. In recent years, the need for radiological identification of anatomical structures has grown with increased dental implant applications in anterior maxillary region with higher esthetic expectations. This study aimed at investigating the NPC's shape and anatomical variations by cone-beam computed tomography (CBCT) in the Turkish society, in a particular region.

Aberrant Anatomical Variation of Maxillary Sinus Mimicking Periapical Cyst: A Report of Two Cases and Role of CBCT in Diagnosis.

Most periapical lesions are associated with microorganisms from infected root canal systems. Maxillary sinus can pose a diagnostic dilemma radiographically because of its anatomical variation which can mimic a periapical pathosis. The aim of this study was to describe two cases of aberrant anatomical variation of the maxillary sinus that presented radiographic similarities to a periapical cyst in order to call the attention of clinicians to the fact that several different diseases are able to mimic endodontic periapical lesions.

Prevalence of bifid mandibular condyle in a Turkish population.

The aim of this study was to determine the frequency of bifid mandibular condyle (BMC) using panoramic radiographs supported by different radiographic techniques. A retrospective study was carried out by evaluating panoramic radiographs of 18,798 patients referred to the Department of Dentomaxillofacial Radiology. T-tests were used to compare the frequency of BMC between left and right sides and between female and male patients.
