Factors Associated with Edentulism among Adult Users of Public Oral Health Services in Victoria, Australia

Abstract

This study examined edentulism (total absence of natural dentition) trends among adults' users of public oral health care in Victoria, Australia and factors associated with these trends. The sample comprised 13,578 dental clients of public oral health care services, collected between July 2008 and June 2009, from which data were complete. The group of edentulous clients represented 6.8% of all clients. Older participants were more likely to be edentulous (OR = 3.95; 95% CI 3.53-4.43). By language spoken at home, those who spoke English were more likely to be edentulous than those who spoke other languages (OR = 1.29; 95% CI 1.02-1.63). Aboriginal clients were more likely to be edentulous than non-Aboriginal clients (OR = 2.21; 95% CI 1.15-4.27). By region of residence, clients living in rural locations were more likely to be edentulous than those living in urban regions (OR = 1.53; 95% CI 1.32-1.78). The full model explained 16.8% of the variance in being edentulous. Findings in edentulism were lower than what was reported by the National Survey of Adult Oral Health. However, despite this trend, significant variations existed across urban and rural locations. Innovative public health programs and services are essential to prevent inequalities in oral health diseases and conditions for rural populations. OPEN ACCESS Dent. J. 2014, 2 99

Effectiveness of health promotion programs in improving oral health of older people in residential aged care facilities: Protocol for a Systematic Review

“…35 It has also been demonstrated from previous studies that access to dental care is poorer in regional and rural areas which results in inequities in oral health outcomes between older people living in urban and rural areas. 36,37 This disadvantage in accessing quality dental care is further exacerbated for older people living in RACF's resulting in a marked decline in oral health after enrolment in RACF's. 11,12 Therefore, an intervention that can address the oral health needs of older people in RACF's in rural areas in a sustainable manner is needed.…”

Evaluation of the Empower model of care for partial denture clients in a public oral health care setting

“…Geographical, as well as socio-economic inequalities in oral health remain as a major public health issue. 32 The approach was successful within a public oral health care service setting. As such it represents an extremely beneficial approach for the implementation of oral health interventions in public health care services.…”

“…However, this does not imply that all refugees or members within an ethnic group are at low risk to oral diseases and conditions. Geographical, as well as socio‐economic inequalities in oral health remain as a major public health issue 32 …”
