Soft tissue calcification on a panoramic

BACKGROUND: The human tissues continuously undergo modification as deposition of calcium (CA) salts either in an organized or disorganized pattern. The latter pattern usually occurs in the soft tissues such as in arteries, brain, kidneys, lungs, and dental pulp. The purpose of this study is to evaluate the presence of pulp calcification and carotid artery calcification (CDC) as a marker for renal calcification and altered serum biomarkers such as serum CA, phosphorus (P), and alkaline phosphatase (ALP)...

OBJECTIVES: The aim of the present study was to evaluate the osseous changes of the jaws of patients with chronic renal failure (CRF) by CBCT. METHODS: On CBCT scans obtained from 15 patients with CRF and 15 control patients (7 males and 8 females), the mean was calculated for the antegonial index (AI), mental index (MI), panoramic mandibular index (PMI) and mandibular cortical index (MCI). The MI, AI and PMI, pulp chamber size, number of teeth with pulp calcification and lamina dura loss were compared using the paired t-test, and the MCI values were analysed using the χ(2) test...

Soft-tissue calcification is always pathological. Metastatic calcification is calcification of soft tissues owing to hyperphosphataemia with or without hypercalcaemia. Metastatic calcification of oral cavity is extremely rare. A case report of metastatic calcification of the floor of the mouth with atypical radiologic and clinical picture is presented here along with a review of earlier reports. A chance finding of the granular oral mucosa on palpation led to a radiographic examination revealing granular calcifications of the floor of the mouth...

The aim of this research is to determine the prevalence of soft tissue calcifications detectable on panoramic radiographs, in the mandibular angle area. 3,028 digital panoramic radiographs taken between June 2009 and June 2011 were evaluated. Soft tissue calcifications found in the mandibular angle area were recorded according to gender, age and bilaterality. Data were analyzed with the Chi squared test and Fisher's exact test, with α< 0.05 being considered statistically significant. The panoramic radiographs analyzed revealed a total of 79 calcifications (2...

Changes related to chronological age are seen in both hard and soft tissue. A number of methods for age estimation have been proposed which can be classified in four categories, namely, clinical, radiological, histological and chemical analysis. In forensic odontology, age estimation based on tooth development is universally accepted method. The panoramic radiographs of 500 healthy Goan, Indian children (250 boys and 250 girls) aged between 4 and 22.1 years were selected. Modified Demirjian's method (1973/2004), Acharya AB formula (2011), Dr Ajit D...

PURPOSE: Tonsilloliths are calcifications found in the crypts of the palatal tonsils and can be detected on routine panoramic examinations. This study was performed to highlight the benefits of cone-beam computed tomography (CBCT) in the diagnosis of tonsilloliths appearing bilaterally on panoramic radiographs. MATERIALS AND METHODS: The sample group consisted of 7 patients who had bilateral radiopaque lesions at the area of the ascending ramus on panoramic radiographs...

OBJECTIVE: The aim of this study was to establish an anatomical guideline in cone beam computed tomography (CBCT) images to discriminate soft-tissue calcifications, specifically, tonsilloliths, and styloid chain ossification (SCO) in the multiplanar reconstruction screen of the i-CAT Vision. MATERIALS AND METHODS: We analyzed 100 pairs of CBCT images and panoramic digital radiographies regarding the presence or absence of tonsilloliths and SCO. The intraobserver agreement varied from excellent to good...

AIM: The aim of this report is to present a case of multiple calcified tuberculous lymph nodes found in a panoramic radiograph including a discussion of the differential diagnosis of this lesion from other soft tissue calcifications. BACKGROUND: Concomitant massive submandibular and cervical tuberculosis lymph node calcifications are relatively uncommon lesions and may be encountered on routine panoramic radiographs. REPORT: This report describes the case of an asymptomatic 35-year-old patient whose dental radiographs showed findings which led to bilaterally, irregularly shaped, multiple calcified lymph nodes especially in the left submandibular and cervical area...

OBJECTIVE: The purpose of this study was to evaluate the frequency of positive radiographic findings in panoramic radiographs of edentulous arches. METHOD: A sample of 327 panoramic radiographs was selected from the patient pool at the University of Oklahoma College of Dentistry. Radiographs were evaluated for presence of retained root tips, impacted teeth, radiolucent and radiopaque areas, soft tissue calcifications, and foreign bodies. RESULTS: Approximately 57...

Tonsillolith is a rare dystrophic calcification as a result of chronic inflammation of the tonsils. Three asymptomatic cases of tonsillolith are reported, incidentally discovered through panoramic radiographs, which showed different sizes of radiopaque images, varying from 2 to 5 mm; cases I and III images did not overlap the mandible ramus, which led to a probable diagnosis of soft tissue calcification. Case II had radiopaque unilateral images, with osseous tissue density, overlapping the mandibular ramus, leading to a benign intra-osseous lesion, which was considered as differential diagnosis...

Benign odontogenic tumors are characterized by imaging findings of expansile growth and well-defined margins with smooth borders, and their appearance is very similar to that of odontogenic and nonodontogenic cysts. From the viewpoint of diagnostic imaging of odontogenic tumors, teeth are designed differently according to their origin from the apex or crown. Therefore, for differential diagnosis, it is necessary to select diagnostic methods that make it possible to evaluate these findings in detail. Intraoral and panoramic radiography are highly effective in examining the relationship between teeth and lesions, especially the vertical relationship...

A case of a large tonsillolith of the left palatine is presented. The lesion was detected incidentally during radiographic examination of a patient presenting with right mandibular pericoronitis. The patient had no symptoms referable to the left tonsillar region. Superimposition of the tonsillolith on the left mandibular ramus on panoramic radiographic examination created the false impression of an intraosseous radiopaque lesion. Many radiopaque structures and lesions occur in the soft tissues close to the jaws and are often observed on panoramic radiographs produced by imaging units with broad focal troughs...

The differential diagnosis of calcified atherosclerotic plaque in the extracranial carotid vasculature includes a number of anatomic and pathologic radiopacities. Most of these are readily distinguishable on the basis of location and morphologic features. The calcified triticeous cartilage, however, can be a confounding alternative that is frequently misdiagnosed as a calcified atheroma. This paper describes the radiographic differences between these 2 entities, enabling clinicians to improve their diagnostic acumen when evaluating cervical soft tissue calcifications...

PURPOSE: Therapeutic irradiation of the neck is a common component of treatment for those with carcinoma of the oral cavity, pharynx, and larynx. Such irradiation, however, has been implicated as the cause of accelerated atherosclerosis of the cervical carotid artery and subsequent stroke. Panoramic radiography, previously shown to be capable of identifying carotid artery atherosclerosis in non-irradiated individuals, was used to assess the carotid vasculature of patients who had been treated for cancer with therapeutic irradiation...

Although stroke may be preventable, a major challenge is to find effective methods of detection of stroke-prone patients. Most noncardiogenic strokes occur as a result of atherosclerosis involving the proximal internal carotid artery, calcifications of which can be detected on dental panoramic radiography. This report describes the case of an asymptomatic patient whose dental radiographic findings led to carotid endarterectomy. Calcifications were viewed bilaterally in the soft tissues of the neck in the area of the carotid bifurcation on a screening panoramic radiograph of an asymptomatic 75-year-old man...

Mapping of the ghost envelope for an Orth Oralix panoramic x-ray unit (Philips Medical Systems) was carried out with a lead sphere suspended at various locations around a dry mandible. The ghost envelope is a three-dimensional zone within which an object or anatomic structure must lie to produce a ghost image on panoramic radiographs. If the three-dimensional shape of the ghost envelope for a particular panoramic unit is known, information can be gained about the clinical location of objects appearing on radiographs produced with that machine...

Not all opacities observed on panoramic dental radiographs are associated with the jaws. Two thousand six hundred and twenty-eight panoramic radiographs obtained from a single dental health clinic were evaluated for the presence of opacities associated with the mandible. Opacities were observed in 4 per cent of cases. The radiographic features of these opacities are presented. The importance of including soft tissue calcifications which may be superimposed over the mandible on panoramic views in the differential diagnosis is discussed...
