We present the case of a 32-year-old male patient complaining of recurrent mandibular pain for 3.5 years. Panoramic radiography indicated increased cortical density of the mandibular lower border. Scintigraphy and single-photon emission computed tomography revealed metabolic hyperactivity in that region without pathologic lymph nodes. A bone biopsy specimen of the mandibular lower border did not have inflammation or cytologic atypia. Endocrinologic investigation confirmed secondary hyperparathyroidism as a result of hypovitaminosis D...

Aim: The aim of the present study is to clarify the possible application of orthopantomogram (OPG) for evaluating craniofacial specifications such as angular and linear measurements of the mandible by comparing with lateral cephalogram. Materials and Methods: OPG and lateral cephalogram were taken from 100 patients of age group 16-35 years from Chettinad Dental College and Research Institute. Linear measurements (body length and ramus height) and angular measurement (gonial angle) were assessed both in lateral cephalogram and OPG...

PURPOSE: This study aimed to investigate the prevalence of juxta-apical radiolucency (JAR), assessing its association with third molar status and describing its radiologic features through panoramic radiography. MATERIALS AND METHODS: We evaluated 1,050 radiographs (1,830 third molars) for the presence of JAR. The JAR and control groups were classified according to the third molar's angulation, impaction, and root development. The presence of radiographic signs of proximity between the mandibular canal and third molar and the imaging features of JAR also were recorded...

OBJECTIVE: The aim of this case-control study was to investigate whether patients with a first myocardial infarction (MI) had a higher prevalence of calcified carotid artery atheromas (CCAAs) on panoramic radiographs (PRs) than age-, gender-, and residential area-matched controls without MI. STUDY DESIGN: Six hundred ninety-six cases with a first MI and 696 controls were included in this substudy of the Swedish multicentre PAROKRANK study. All participants underwent panoramic radiography, and the PRs were evaluated for CCAAs...

To compare alveolar ridge splitting (ARS) and autogenous onlay bone grafting (AOBG) in atrophic jaw bones.  Methods: Forty patients were included in this retrospective, parallel-group study conducted at the Istanbul Medipol University School of Dentistry, Istanbul, Turkey, between 2012-2015. The initial bone thickness was measured by cone beam computed tomography (CBCT). Patients were allocated into ARS (n=17) and AOGB (n=23) groups on the basis of ridge thickness and shape. Follow-up CBCT measurements to assess horizontal bone were repeated 4 to 6 months post augmentation...

In this review, we aimed to depict the clinical, radiological, and genetic features of cleidocranial dysplasia (CCD) and to suggest management guidelines, based on our experience of 8 cases, with an emphasis given to dental complications.The most common craniofacial features of CCD that stand out are a patency of the anterior fontanelle, an inverted pear-shaped calvaria, a hypertelorism, a general midface retrusion, and a mandible prognathism, associated with an excessive mobility of the shoulders, a short stature, and teeth abnormalities such as supernumerary teeth and failure of eruption, in particular...

OBJECTIVE: The objective of the study was to compare estimates of pediatric cumulative exposure and lifetime attributable risk (LAR) of radiation-induced cancer from dental radiology between cleft palate (CP) subjects and age- and gender-matched controls (non-CP), with and without orthodontic treatment. MATERIALS AND METHODS: The radiation exposure frequency of CP subjects and non-CP controls with and without orthodontic treatment was compared for two-dimensional radiography (intra-oral, panoramic and cephalometric radiography), computed tomography (CT), and cone-beam CT (CBCT) using cumulative radiation dose as an estimate...

OBJECTIVES: To assess the validity of digital panoramic radiographs as an effective means of diagnosis for atherosclerosis and as a potential aid in the early detection of the disease. STUDY DESIGN: We reviewed 2014 digital panoramic radiographs taken throughout 2012 and 2013 to identify the presence of calcified atherosclerotic plaques of both female and male patients all aged over 18 years. In addition the medical records of these patients were reviewed in order to establish if there were any predisposing risk factors for atherosclerosis...

BACKGROUND: Root resorptions are assessed and diagnosed using different radiographical techniques. A comparison of the ability to assess resorptions on two-dimensional (2D) and three-dimensional (3D) radiographs is, hitherto, lacking. The aims of this study were to evaluate the accuracy of 2D (periapical radiographs, PA and panoramic radiograph, PAN) and 3D (cone beam computed tomography, CBCT) radiographic techniques in measuring slanted root resorptions compared to the true resorptions, a histological gold standard, in addition to a comparison of all the radiographic techniques to each other...

Presenting patients with the opportunity to restore their smiles using dental implants, which is a reliable and widely accepted technique, is highly recommended. Therefore, a correct clinical judgment and a, consequently, dental implant treatment planning is a central component of a good practice of implant dentistry. Moreover, to the oral clinician be able to make better decisions and reach a more accurate clinical judgment, it is necessary continuing professional development being, this development, an essential professional activity for dentists that intend planning implant treatments...

Objectives: The present evaluate the feasibility of Computed tomography (Dentascan), in assessment of the implant site in posterior maxilla & mandible. Material and Methods: data of total 11 patients with 20 implant sites were involved in the present study. Out of the 20 implant sites selected 10 were in posterior maxilla and 10 in posterior mandible. All the patients were routinely examined by panoramic radiography and CT. All images obtained i.e., conventional panoramic radiograph, and film based Dentascan MPR- CT images were evaluated for the detectability of mandibular canal at the mental foramen, 1 cm, 2 cm, and 3 cm posterior to mental foramen...

Maxillary cysts, including the cysts lined by respiratory epithelium, can present a diagnostic challenge. We report an unusual case of a maxillary cyst on an endodontically treated tooth #16, in which the cavity was totally lined by a respiratory epithelium. The patient, a 35-year-old male, presented with a generalized chronic periodontitis and complained of a pain in the tooth #16 region. A periodontal pocket extending to the root apices with pus coming out from the gingival was found. A combined endodontic periodontal was observed on a panoramic radiography...

Chest wall ultrasound has been awarded little interest in the literature, with chest wall anatomy described only in limited extent. The objective of this study has been to discuss the methodology of chest wall ultrasound and the sonographic anatomy of the region to facilitate professional evaluation of this complex structure. The primarily used transducer is a 7-12 MHz linear one. A 3-5 MHz convex (curvilinear) transducer may also be helpful, especially in obese and very muscular patients. Doppler and panoramic imaging options are essential...
