Attitudes and beliefs of oral health professionals regarding their role in health promotion

Issues addressed: The study was designed to gain an understanding of health promotion from the perspective of oral health professionals employed in the public sector during a transition in the focus of services. Methods: A cross sectional survey of oral health professionals employed by Queensland Health was conducted between March and April 2001. Staff were randomly sampled from employment records. A proportionate random sample, stratified across professional groups and geographical zones, was selected. Results: While the majority of the health professionals surveyed perceived oral health promotion to be part of their role, they felt ill equipped to adopt it. Professional groups differed in their confidence and perception of how to promote health in their clinical setting, existing barriers they encountered and their participation in health promotion programs. Conclusions: Strategies to improve the adoption of the oral health promotion role within Queensland public oral health services include: regular in- service and education for all staff regarding health promotion issues; increased cohesion of the oral health team; intersectorial collaboration; supportive district management; and a refocus to primary health care and public health concepts

The experiences and perceptions of unit managers in facilitating oral health in adults with intellectual disability

This qualitative research investigated the experiences and perceptions of unit managers regarding their involvement with oral health management of adults with intellectual disability. Semi-structured individual interviews were conducted with eight participants working in four different area offices of a metropolitan disability service, whose experience as unit managers ranged from 1 to 17 years. Key themes identified in the interview data focused on unit managers' views of the oral health of this group, the support roles involved in the oral health of adults with intellectual disability, the priority of oral health, the experiences of the participants within the oral health system, and the strategies for supporting adults with intellectual disability in oral health management. Implications of the findings included the need to improve education for all persons involved in the oral health of adults with intellectual disability, to encourage a collaborative approach to oral health by workers within accommodation support services and the oral health system, and to enable adults with intellectual disability to maximally participate in their own oral health management.

Eating disorders and oral health: A review of the literature

This article is a review of the recent literature pertaining to the oral sequelae of eating disorders (EDs). Dentists are recognized as being some of the first health care professionals to whom a previously undiagnosed eating disorder patient (EDP) may present. However, despite the prevalence (up to 4 per cent) of such conditions in teenage girls and young adult females, there is relatively little published in the recent literature regarding the oral sequelae of EDs. This compares unfavourably with the attention given recently in the dental literature to conditions such as diabetes mellitus, which have a similar prevalence in the adult population. The incidence of EDs is increasing and it would be expected that dentists who treat patients in the affected age groups would encounter more individuals exhibiting EDs. Most of the reports in the literature concentrate on the obvious clinical features of dental destruction (perimolysis), parotid swelling and biochemical abnormalities particularly related to salivary and pancreatic amylase. However, there is no consistency in explanation of the oral phenomena and epiphenomena seen in EDs. Many EDPs are nutritionally challenged; there is a relative lack of information pertaining to non-dental, oral lesions associated with nutritional deficiencies.

Genetic and environmental influences on dentofacial structures and oral health: studies of Australian twins and their families

Our studies of the teeth and faces of Australian twins commenced at the School of Dentistry, The University of Adelaide in the early 1980s. There are now over 900 pairs of twins enrolled in our continuing investigations, together with 1200 relatives. There are 3 main cohorts of participants. The first cohort comprises around 300 pairs of teenage twins for whom various records have been collected, including dental casts, facial photographs, finger and palm prints and information on laterality, including handedness. The second cohort comprises around 300 pairs of twins who have been examined at 3 stages of dental development from approximately 4 years of age to about 14 years: at primary, mixed, and permanent dentition (excluding 3rd molars) stages. The most recent study of tooth emergence and oral health, for which we are currently recruiting twins, will provide a third cohort of around 500 twin pairs aged from around birth to 3 to 4 years of age. Our broad aim in these studies has been to improve our understanding of how genetic and environmental factors contribute to variation in dental and facial features, and to oral health. We have also used our data to investigate aspects of the determination of laterality, particularly the fascinating phenomenon of mirror imaging. We plan to maximize the use of the longitudinal data and DNA we have collected, and continue to collect, by performing genome-wide scans for putative genetic linkage peaks for a range of dental features, and then to test for association between a series of likely candidate genes and our phenotypes.

Oral disease in animals: The Australian perspective. Isolation and characterisation of black-pigmented bacteria from the oral cavity of marsupials

A wide range of animals suffer from periodontal disease. However, there is very little reported on disease and oral micro-biota of Australian animals. Therefore, the oral cavity of 90 marsupials was examined for oral health status. Plaque samples were collected from the subgingival margins using curettes; or swabs. Plaque samples were plated onto. non-selective trypticase soy agar plates, selective trypticase soy agar, non-selective and selective Wilkens Chalgrens, Agar. Plates were incubated in an anaerobic atmosphere and examined after 7-14 days for the presence of black-brown-pigmented colonies. A combination of morphological and biochemical tests were used (colonial morphology, pigmentation, aerobic growth, Gram reaction, fluorescence under long-wave UV light (360 nm), production of catalase, enzymatic activity with fluorogenic substrates and haemagglutination of sheep red cells) to identify these organisms. Black-pigmented bacteria were cultivated from the plaque of 32 animals including six eastern grey kangaroos, a musky rat kangaroo, a whiptail and a red-necked wallaby, 18 koalas, a bandicoot and five brushtail possums. No black-pigmented colonies were cultivated from squirrel or sugar gliders or quokkas or from marsupial mice. The majority of isolates were identified as Porphyromonas gingivalis-like species with the higher prevalence of isolation from the oral cavity of macropods (the kangaroos and wallabies). Oral diseases, such as gingivitis can be found in native Australian animals with older koalas having an increase in disease indicators and black-pigmented bacteria. Non-selective Wilkens Chalgren Agar was the medium of choice for the isolation of black-pigmented bacteria. (C) 2002 Elsevier Science Ltd. All rights reserved.
