Sialolithiasis is one of the most frequent form of calcifications in the maxillofacial area. 0.45% of the population is affected by symptoms caused by salivary calculi, though the estimated frequency including asymptomatic form may exceed 1% in adult population. Radiographs presenting a large portion of the maxillofacial region (panoramic radiography, computed tomography) could detect salivary calculi with high accuracy. The size of the sialoliths is usually less than 10 mm in diameter. Salivary calculi larger than 15 mm (considering the largest diameter) are classified as giant sialoliths and most of them are located in the submandibular gland or in its duct...

BACKGROUND: A dentist always checks a patient by using panoramic radiography (PR) initially. The measurement of the minimal distance (MD) between the alveolar crest and the mandibular canal (MC) superior border is critically important before the dental implant surgery, extraction of 3rd molar teeth or any surgery in the posterior area of minimal distance (MD). However, the image of MC is not always clear to identify. OBJECTIVE: A software is needed for training dentists as well as a tool of demonstration to patients in clinics precisely and quickly...

Venous malformations are congenital, abnormally formed vessels, present at birth. They do not undergo regression with the growth of the patient. Due to the stagnation of blood flow in venous malformations, thrombosis and phlebolith formation may occur. Phleboliths are calcified thrombi which radiographically must be differentiated from calcified lymph nodes, sialoliths, foreign bodies, and other radiopacities. We report an extensive venous malformation in a 19-year-old woman with panoramic radiography demonstrating multiple phleboliths...

Exact localization of foreign body is important for planning the treatment required for its retrieval without much tissue damage. Plain film radiography is the initial screening modality used for the detection of suspected foreign body. However, about one-third of all the foreign bodies are missed in the initial radiographic examination. In case of a wooden foreign body, only 15% are well-visualized on plain radiographs and are, therefore, often missed or misdiagnosed. Hence, the different radiographic technique should be used to localize the object instead of relying on a single radiographic image...

Bisphosphonates have established their role as medical therapy for pediatric osteogenesis imperfecta (OI) patients. Since bisphosphonates have also been shown to delay tooth development in animal models, we aimed to assess whether the medication has a similar effect on children with OI. In this cross-sectional study, bisphosphonate-treated OI patients of whom dental panoramic tomograph was taken between 3 and 16years of age formed the study group. The patients, 22 in total, had been treated with pamidronate, zoledronic acid or risedronate for at least one year before the radiography...

A static, unilateral, and focal bone depression located lingually within the ascending ramus, identical to the Stafne's bone cavity of the angle of the mandible, is being reported. During development of the mandible, submandibular gland inclusion may lead to the formation of a lingual concavity, which could contain fatty tissue, blood vessels, or soft tissue. However, similar occurrences in the ascending ramus at the level of the parotid gland are extremely rare. Similar cases were previously reported in dry, excavated mandibles, and 3 cases were reported in living patients...
