Diagnosing ingested dental prostheses can be difficult and delays in treatment may result in serious complications. Patients often present with a vague history and very few reliable clinical signs. In addition, the fact that dental plates are often radiolucent may lead to the diagnosis being overlooked with disastrous consequences. A case of successful diagnosis and treatment is presented, and ...

introduction calcifying odontogenic cyst (coc) is a unique and uncommon odontogenic cyst classified into four groups of cystic, odontoma producing, ameloblastomatous proliferating and neoplastic ones. case presentation a 34-year-old iranian man complaining of a painless facial and palatal swelling of the left side of the maxilla persisted for approximately three years was referred to the depart...

BACKGROUND The radiographic criteria for identification of loose cementless acetabular components have not been well established. The purpose of this study was to compare the radiographic appearance of a hemispheric porous-coated cementless cup fixed with screws with the intraoperative findings with regard to the fixation status. METHODS The quality of the cup fixation was evaluated at fifty-...

We examined the radiographs from a prospective clinical study of fixation by pedicle screws and those from an experimental study in a sheep model. In the clinical study, instruments were removed from 21 patients after implantation for 11 to 16 months and the extraction torques of the screws were recorded. A structured protocol was used for the radiological examinations. In the experimental stud...

The radiographic and histological features of radiolucent areas at the cement-bone interface were correlated in 15 specimens retrieved at post-mortem from patients who had undergone cemented total hip arthroplasty, two weeks to 15 years prior to death. All but one of the components were securely fixed, as demonstrated by direct measurements of micromotion. Extensive radiolucencies were present ...

Radiolucent lines at the bone-cement interface beneath the tibial components were assessed in 91 consecutive Oxford meniscal knee replacements in 78 patients. Of 80 knees in which radio-opaque cement was used, a radiolucent line was observed in 77, with a radiodense line in the bone immediately adjoining. Radiolucent lines developed in the majority of patients within one year after operation. I...

In this study, we formulate a new proposal that complements previous classifications in order to assist dental practitioners in performing a differential diagnosis based on patients' radiographs. We used general search engines and specialized databases such as Google Scholar, PubMed, PubMed Central, MedLine Plus, Science Direct, Scopus, and well-recognized textbooks to find relevant studies by ...

A 23-year-old female patient presented with diffuse swelling causing intermittent pain involving the left side of face that had been present for over 10 years. Extra-oral examination revealed expansile lesions in maxilla and mandible, appeared mixed radiolucent-radiopaque on panoramic radiography. The maxillary lesion resulted opacification sinus. mandible trabecular bony changes larger radiolu...
