Background: Osteoporosis is a systemic skeletal disease characterized by low bone mineral density (BMD) and micro-architectural deterioration of bone tissue, leading to bone fragility and increased fracture risk. Since Panoramic image is a feasible and relatively routine imaging technique in dentistry; it could provide an opportunistic chance for screening osteoporosis. In this regard, numerous...

conclusions there was no statistically significant difference in the parotid absorbed dose between spiral tomography and a panoramic radiograph (p value = 0.18). the overall results of this study were similar to other studies. results for the tube side parotid, the average absorbed doses in spiral tomography of the anterior and posterior parts of the maxilla and mandible, with the 2 mm slice th...

conclusions the relationship between cac found on dental panoramic radiographs and two cva risk factors--hypertension and mi-- was significant. therefore, it seems that detection of cac on panoramic images of dental patients must be considered by dentists. results among 200 studied samples, 22 of the patients (11%) had carotid artery calcification on the dental panoramic radiograph. in total, 5...

Cone-beam computed tomography (CBCT) has become popular, and its many inherent advantages are indisputable. Nevertheless, CBCT is prescribed cautiously because the radiation dosage is higher than that of conventional radiography. When and to what extent should CBCT be prescribed for orthodontic patients? The purpose of this article is to present 4 curious cases in which a considerable discrepan...

Developmental anomalies in tooth structure can involve dental enamel, dentin, pulp, cementum, or a combination of these tissues. While relatively precise typing of some of these anomalies is now possible using techniques in molecular biology, radiography remains important in the assessment of phenotypic manifestations and is often essential in treatment-planning for esthetics and function of de...

The objective of this case report is to help clinicians identify bifid mandibular canals on panoramic radiographs and subsequently use the information in the modification of dental treatment planning. A 45-year old man was referred to the service of Oral Diagnosis and Radiology. Routine panoramic radiography, suggested the presence of bilateral bifid mandibular canals (BMC). Mandibular computed...

One of the most common positioning errors in panoramic radiography is the palatoglossal air space above the apices of the root of maxillary teeth. It causes a radiolucency obscuring the apices of maxillary teeth. In the case of this positioning error, the imaging should be repeated. This causes the patient to be exposed to radiation again. To avoid the repetition of exposing harmful X-rays to t...
