Comparison of photothermal radiometry and modulated luminescence, intraoral radiography, and cone beam computed tomography for detection of natural caries under restorations
ConclusionPTR/LUM, which involves non-ionizing radiation, can serve as a sensitive adjunct in early caries detection and monitoring.
Objective: To compare the rate of malreduction after high fibular fractures associated with syndesmosis injury treated with open reduction and internal fixation, with either 2 screws or 1 knotless TightRope device. Design: Prospective randomized controlled multicenter trial. Setting: Eleven academic and community hospitals including Level 1 and Level 2 trauma centers across Canada. Patients/Participants: One hundred three patients with OTA/AO 44-C injuries with demonstrated radiographic syndesmosis diastasis or instability after malleolar bony fixation were followed for 12 months after treatment. Methods: Ope...
CONCLUSIONS: Impacted maxillary canines are usually diagnosed by using panoramic imaging or cone-beam computed tomography. Cone-beam computed tomography is the most accurate diagnostic method to identify the localisation of impacted maxillary canines. Palatal expansion can help to avoid the impaction of maxillary canines. Combined surgical and orthodontic treatment is used to treat impacted maxillary canines in permanent dentition.

We present images of 177Lu-DOTATATE scan and 68Ga-DOTATATE PET/CT scan conducted on a 65-year-old man with prostate cancer with neuroendocrine differentiation, whose disease progressed despite conventional treatment and 177Lu-PSMA radioligand therapy; however, an extraordinary radiographic tumor remission, biochemical response, and improvement of clinical symptoms were observed after the patient underwent 177Lu-DOTATATE peptide receptor radionuclide therapy.
The objective of this study was to compare the novel extraction-site development (XSD) technique with spontaneous healing. Advanced alveolar defects (extraction defect sounding, classes 3 and 4) at 33 single-rooted teeth were treated by XSD (test), and 21 extraction sites of single-rooted teeth were left for spontaneous healing (control). In pre- and postoperative cone beam computed tomography (CBCT) data sets, orovestibular and vertical socket dimensions were assessed, as were socket areas. XSD resulted in complication-free healing with significantly higher radiographic bone fill compared to spontaneous healing. Applicati...
ConclusionLWAT is a reliable procedure that provides sustained protection against patello-femoral dislocation and good functional scores when used to treat patello-femoral instability due to trochlear dysplasia. Our results do not support claims that LWAT may be associated with high rates of severe osteoarthritis even after more than 20 years.Level of evidenceIV, retrospective observational study with no control group.
This study was aimed to estimate the length of the MIC in the interforaminal safe zone, to analyse its course in relation to the lingual and the buccal cortical plates of the mandible using cone beam computed tomography (CBCT) scans and to relate the above findings to age, gender, dental status and Malaysian races.MethodsRetrospective analysis of 100 CBCT scans (n = 200) was performed on both sides of the mandible. Cross-sectional and panoramic images were reconstructed. The length of the MIC and the horizontal distances between the MIC and the buccal and the lingual cortical plates were measured at the three...
There is a wide variety of causes of diffuse lung disease in the intensive care unit patient, of which adult respiratory distress syndrome is the commonest clinical consideration. Plain radiography, computed tomography, and ultrasound can be used synergistically to evaluate patients with diffuse lung disease and respiratory impairment. Imaging is not limited to characterization of the cause of diffuse lung disease but also aids in monitoring its evolution and in ventilator setting management.
Conclusions: These findings demonstrated the efficacy of interbody closed-box spacers for PLIF without the need to fill the spacer with autologous bone. However, the risk of non-union should be considered in elderly patients, especially intra-operatively and during the early postoperative stage. PMID: 31608613 [PubMed - as supplied by publisher]
ConclusionsThe carotid bifurcation is in close proximity to various calcified anatomical structures. This should be taken into account when diagnosing CCPs in panoramic radiographs (PRs). In the coronal view, CCPs and the cervical spine are often superimposed; thus, coronal images are not recommended for confirmation of putative carotid calcifications diagnosed on PRs.
CONCLUSIONS: Distally placed volar locking plate fixation effectively treats intra-articular distal radius fractures with VLF fragments distal to the watershed line by stabilizing the fragments. However, small displaced VLF fragments may increase the risk of reduction loss in ulnar variance. PMID: 31611505 [PubMed - as supplied by publisher]
