“…In the 2013 report the rate in WA was higher than in any other state or territory in Australia. Our findings also indicate higher rates than those found in New Zealand (2.15 per 1000 population in 2005–2009) . Although there was an over‐representation in the proportion of Aboriginal people in our study (4.4% of all admissions), and an overall higher rate among Aboriginal people, there was not a significant difference in rates between Aboriginal (3.34 per 1000) and non‐Aboriginal people (3.26 per 1000).…”

“…Potentially avoidable hospitalizations related to oral health were defined as the following: principal diagnosis categories K02 Dental Caries; K03 Other diseases of hard tissues of teeth; K04 Diseases of the pulp and periapical tissues; K05 Gingivitis and periodontal diseases; K06 Other diseases of gingival and edentulous alveolar ridge; K08 Other disorders of teeth and supporting structures; K09.8 Other cysts of oral region, not elsewhere classified; K09.9 Cysts of oral region, unspecified; K12 Stomatitis and related lesions; and K13 Other diseases of lip and oral mucosa. These categories were selected to match those used by the Australian Institute of Health and Welfare (AIHW) in reports on oral health, and are identical to those used previously in other Australian and international studies …”

“…Avoidable hospitalization rates for dental care has also shown to be higher among rural dwellers and children younger than 9 years, but little association between socio‐economic deprivation and hospitalization rates was found in a study from Victoria, Australia . However, a recent analysis from New Zealand indicated higher rates of dental preventable hospitalizations among the most deprived …”

Background: The aims of this study were to assess the rates of hospitalizations for potentially preventable dental conditions over a 10-year period in Western Australia; to analyse trends over 10 years in rate changes of hopitalizations; and to analyse the mix of preventable dental conditions by age group and Aboriginal status. Methods: The principal diagnosis, as classified by the International Classification of Disease (ICD-10AM), was used to select hospitalization data for all patients who were discharged from hospital in Western Australia for the financial years 1999-2000 to 2008-2009, for a potentially preventable oral health condition. Results: Over a 10-year period more than 65 000 people were hospitalized. Population rates of hospitalization increased significantly over the period for both Aboriginal and non-Aboriginal population groups. Admission rates were higher for Aboriginal people. Children under 14 were more likely to be admitted; the most common condition that required hospitalization was dental caries, and the highest rates of hospitalization were for those from the most socio-economically disadvantaged areas. Conclusions: These hospitalizations remain a considerable and increasing financial burden on health budgets. An increase in efforts is necessary to curb escalating government health expenditure by reducing avoidable and preventable oral health related hospitalizations.Keywords: Australia, dental, hospitalizations, oral health, preventable.Abbreviations and acronyms: AIHW = Australian Institute of Health and Welfare; AR-DRG = Australian refined standard diagnostic related group; ARIA = Accessibility and Remoteness Index of Australia; HMDS = hospital morbidity data system; SEIFA = Socio-economic Index for Areas.

Background We examined the association between area-level deprivation and dental ambulatory sensitive hospitalizations (ASH) and considered the moderating effect of community water fluoridation (CWF). The hypothesis was that higher levels of deprivation are associated with higher dental ASH rates and that CWF will moderate this association such that children living in the most deprived areas have greater health gain from CWF. Methods Dental ASH conditions (dental caries and diseases of pulp/periapical tissues), age, gender and home address identifier (meshblock) were extracted from pooled cross-sectional data (Q3, 2011 to Q2, 2017) on children aged 0–4 and 5–12 years from the National Minimum Dataset, New Zealand (NZ) Ministry of Health. CWF was obtained for 2011 and 2016 from the NZ Institute of Environmental Science and Research. Dental ASH rates for children aged 0–4 and 5–12 years (/1000) were calculated for census area units (CAUs). Multilevel negative binomial models investigated associations between area-level deprivation, dental ASH rate and moderation by CWF status. Results Relative to CWF (2011 and 2016), no CWF (2011 and 2016) was associated with increased dental ASH rates in children aged 0–4 [incidence rate ratio (IRR) = 1.171 (95% confidence interval 1.064, 1.288)] and aged 5–12 years [IRR = 1.181 (1.084, 1.286)]. An interaction between area-level deprivation and CWF showed that the association between CWF and dental ASH rates was greatest within the most deprived quintile of children aged 0–4 years [IRR = 1.316 (1.052, 1.645)]. Conclusions CWF was associated with a reduced dental ASH rate for children aged 0–4 and 5–12 years. Children living in the most deprived areas showed the greatest effect of CWF on dental ASH rates, indicating that the greater health gain from CWF occurred for those with the highest socio-economic disadvantage. Variation in CWF contributes to structural inequities in oral-health outcomes for children.
