Dental erosion: In vitro model of wine assessor's erosion
The document attached has been archived with permission from the Australian Dental Association. An external link to the publisher’s copy is included.Background: Wine makers and assessors frequently experience severe dental erosion. The objectives of this study were to develop an in vitro model of dental erosion caused by frequent wine contact with teeth, and to use this model to assess the effectiveness of a variety of methods which might protect against this form of erosion. Methods: An initial pilot study found that riesling style wine was more erosive than champagne style, and both more than claret. Wine tasting was simulated by subjecting exposed windows of enamel and root surfaces on 50 intact, extracted human teeth to 1400 one minute exposures to white wine (pH 3.2). A variety of dental materials were applied to the exposed windows on groups of teeth prior to erosive challenge, to assess their protective ability. Results: Protective resin coatings and fluoride varnishes protected both enamel and roots against wine induced erosion. A high degree of protection was provided by APF gel, with less by NaF gel. Conclusions: It was concluded that dentists may be able to help minimise erosion resulting from frequent wine-tasting in their patients by the clinical application of one or a combination of these agents at times prior to prolonged assessment periods.Tong Bee Mok, J McIntyre and D Hun
Computer program documentation for the pasture/range condition assessment processor
The processor which drives for the RANGE software allows the user to analyze LANDSAT data containing pasture and rangeland. Analysis includes mapping, generating statistics, calculating vegetative indexes, and plotting vegetative indexes. Routines for using the processor are given. A flow diagram is included
Visible and near infrared spectroscopy of Hayabusa re-entry using semi-autonomous tracking
A ground-based tracking camera and co-aligned slit-less spectrograph were used to measure the spectral signature of visible radiation emitted from the Hayabusa capsule as it entered into the Earth's atmosphere in June 2010. Good quality spectra were obtained that showed the presence of radiation from the heat shield of the vehicle and the shock-heated air in front of the vehicle. An analysis of the black body nature of the radiation concluded that the peak average temperature of the surface was about (3100±100) K
Management of patients with non-syndromic clefts of the lip and/or palate Part 2:from primary surgery to alveolar bone grafting
Part 1 of this series of articles addressed the care of the child with a cleft of the lip and/or palate from antenatal diagnosis until primary surgery. The second part of this article discusses their care from primary surgery until alveolar bone grafting. Clinical Relevance: Dentists should be aware of the different types of cleft lip and/or palate that occur and the role of the dentist in the overall management of patients who have clefts. </jats:p
Management of patients with non-syndromic clefts of the lip and/or palate Part 3:from age 10 to adulthood
Management of patients with non-syndromic clefts of the lip and/or palate Part 1:from antenatal diagnosis to primary surgery
Patients with clefts of the lip and/or palate require input from a diverse group of medical, surgical, dental and parasurgical specialties working as part of a multidisciplinary team in the UK. Co-ordinated care ensures that the patient receives optimal treatment whilst minimizing the burden of care for the NHS and family. The primary care dentist has an important role in the overall management of patients with clefts. Because the dentist-patient/parent relationship is of a long-term nature, the primary care dentist can also provide useful support and advice for families as they progress through the care pathway. This three-part article will illustrate the integration of dentistry with the other aspects of care. Clinical Relevance: Dentists should be aware of the different types of cleft lip and/or palate that occur and the role of the dentist in the overall management of patients who have clefts. </jats:p
