Background:Patients who play musical instruments (especially wind and stringed instruments) and vocalists are prone to particular types of orofacial problems. Some problems are caused by playing and some are the result of dental treatment. This paper proposes to give an insight into these problems and practical guidance to general practice dentists. Method: Information in this paper is gathered from studies published in dental, music and occupational health journals, and from discussions with career musicians and music teachers. Results: Orthodontic problems, soft tissue trauma, focal dystonia, denture retention, herpes labialis, dry mouth and temporomandibular joint (TMJ) disorders were identified as orofacial problems of career musicians. Options available for prevention and palliative treatment as well as instrument selection are suggested to overcome these problems. Conclusions: Career musicians express reluctance to attend dentists who are not sensitive to their specific needs. General practitioner dentists who understand how the instruments impact on the orofacial structures and are aware of potential problems faced by musicians are able to offer preventive advice and supportive treatment to these patients, especially those in the early stages of their career.
Queensland had its advocates for artificial water fluoridation of communal supply as a means of caries prevention. Interest came from the dental, medical and engineering professions, and from the sugar industry. However, these efforts met with indifference based on confused extrapolation of the artesian experience (1945-1952) and hesitancy (1952-1954) due to contemporaneous concerns about human fluid homeostasis in Queensland's sub-tropical climate.
Inquiries into the diminishing supply of artesian water within the Queensland aspect of the Great Artesian Basin began in 1939. These investigations produced a Queensland phenomenon without Australian precedent in terms of rationale, geographical diversity, and commitment of resources. In some regions, exposure of herds to fluoride emerged as an urgent issue because fluoride was perceived as an invasive, invisible, and odourless 'contaminant' in artesian water. This paper discusses the scientific background to, and management of, concerns over the consumption by stock of artesian water with a high concentration of natural bioavailable fluoride. The Queensland Department of Agriculture and Stock managed the problem by scientific investigation, methodical field study, and the application of research findings to animal husbandry. The practical solutions arrived at involved rotation of stock on an age-related basis to and from certain bore supplies, fencing young sheep away from the artesian supply, fencing young sheep near the bore-head, and limiting the use of supplements.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
