Eight-hundred-and-twenty-two British orthodontists were sent questionnaires regarding their use of ceramic brackets. Five-hundred-and-forty-six (66 per cent) responded, and from these, 512 (62 per cent) were analysed. Approximately half of these operators had experience with ceramic brackets, but only 32 operators had treated more than 30 patients.(More)
Since the discovery of low-dimensional carbon allotropes, there is increasing interest in using carbon nanomaterials for biomedical applications. Carbon nanomaterials have been utilized in the biomedical field for bioimaging, chemical sensing, targeting, delivery, therapeutics, catalysis, and energy harvesting. Each application requires tailored surface(More)
A retrospective study was undertaken using treated functional appliance cases. The groups involved 27 Andresen, 19 Bionator, and 23 Fränkel cases. The reflex metrograph was used to measure arch width from study models at the start of treatment, end of treatment including retention, and at least 1 year post-treatment. The effects of each appliance on arch(More)
Orthodontists are often concerned about the prognosis of root-filled teeth, particularly when extractions are required for orthodontic treatment. This review provides guidance on assessing the quality of root fillings, as well as the factors which affect the prognosis of root-filled teeth. The implications of previous traumatic injuries and the likelihood(More)
Although our investigations reveal a number of significant astronomical events coinciding with many of the measured alignments presented in Table 1, not every alignment appears to have an astronomical match which we can recognize. It may be that only some of the sighting possibilities we have discussed were actually functional. Moreover, our search of(More)
Laparoscopic cholecystectomy has led to an increase in preoperative endoscopic retrograde cholangiopancreatography (ERCP) for the investigation of bile duct stones. ERCP and intravenous infusion cholangiography (IIC) were compared in 111 consecutive patients without jaundice considered to be at high risk for bile duct stones. Both investigations were(More)
