Influence of cone-beam computed tomography image artifacts on the determination of dental arch measurements.
Conclusion: CBCT provided the same accuracy as DPM in the measurement of the dental arches, and was negatively influenced by the presence of image artifacts. PMID: 23924404 [PubMed - as supplied by publisher]
Conclusions: The maximum length of the coracoid available for transfer in Malasian Malay patients was less than what has been recommended in the literature for the Latarjet procedure. The surface area that would be increased after a coracoid graft is placed on the glenoid would be 12.4±1.8 mm. Knowledge obtained from this study may help us further optimize osseous considerations for the Latarjet procedure in the Malaysian Malay population. Level of Evidence: Level III.
AbstractObjectivesTo test if the partially digital workflow by digitalisation of the impression reveals a comparable accuracy as the indirect digitalisation of the gypsum cast for 4-unit fixed dental prostheses (FDPs).Materials and methodsA titanium model with a tapered full veneer preparation of a molar and premolar was used as analysis model. To receive a virtual three-dimensional reference dataset (REF), it was digitised by industrial computed tomography. Three impression materials were used with individual impression trays (N = 36,n/material = 12): (1) PE (Impregum Penta), (2) PVS-I (Imprin...
ConclusionsAnterior osteotomy just to the midline of inferior border and horizontal osteotomy to the mandibular foramen are associated with split patterns that result in optimal rigid fixation and passive bony overlap for OSA patients undergoing MMA.Clinical relevanceOptimal surgical technique has the most significant influence in allowing rapid return to function after MMA in patients with OSA.
ConclusionsThis patient presented with amnesia which is a rare presentation of hypoparathyroidism.
ConclusionCT was a more effective diagnostic tool for the diagnosis of irreversible gastric necrosis following caustic ingestion than a strategy based on digestive endoscopy and the use of CBSC. CT could eventually replace gastrointestinal endoscopy in the emergency evaluation of gastroesophageal caustic burns.
ConclusionPneumorrachis is usually asymptomatic and is self-limiting. It is a radiological diagnosis and is not a clinical diagnosis. CT scan is considered the preferred diagnostic method for reliable and rapid detection of pneumorrachis. In case of coexistence, The physician should be alert to diagnose and treat the underlying cause for related injuries.In such cases, successful results can be obtained with hyper-oxy therapy (100% oxygen inhalation) and antibiotic prophylaxis without the need for surgical treatment.
ConclusionAlthough rare, osteoid osteoma may occur in the hallux. Even if the patient age, pain pattern, and radiographic findings do not exactly meet the classical definitions for osteoid osteoma, this tumor should always be included in the differential diagnosis list in patients presenting with foot pain.
The purpose of this study was to compare the ex vivo bovine liver ablation zone volume data provided by the manufacturer with measured ablation zone volumes on post procedure CT scans following hepatocellular carcinoma ablation with the Solero Microwave Tissue Ablation System (AngioDynamics).
To compare procedure duration and patient radiation dose in PET/CT and CT-guided liver tumor ablation procedures.
This study aimed to determine the effect of implementation of a low-dose computed tomography (CT)-guided thoracic biopsy protocol on (1) radiation doses associated with CT-guided thoracic biopsies and (2) complication rates when compared to standard thoracic biopsy protocol CT.
