  • + Notes

    Only NSW residents are included. Rehabilitation episodes are excluded, unless otherwise stated. Figures are based on where a person resides, rather than where they are treated. Hospital separations were classified using ICD-10-AM. Rates were age-adjusted using the Australian population as at 30 June 2001.

    Patients treated solely within the emergency department are excluded from this indicator report due to a policy change (PD2017_015). Please note that a minority of patients being managed in short stay areas of emergency departments are still included. Further information is found in a paper in the HealthStatsPLUS Methods tab on this website.

    Numbers for recent years include an estimate of the small number of hospitalisations of NSW residents in interstate public hospitals, data for which were unavailable at the time of production. Further details can be found in the Methods tab in the following HealthStats NSW indicator:

    LL/UL 95%CI = lower and upper limits of the 95% confidence interval for the point estimate.

  • + Commentary

    Major contributing factors to dental caries in children are poor dietary and oral hygiene practices. Young children may be more likely to be admitted to hospital because dental procedures may be difficult to perform in outpatient settings at this age. Dental caries continue to be a reason for treatment in hospital under general anaesthetic. Dental procedures included are removal and/or restoration of teeth.

    • Key points: Oral health

      Overall, oral health in NSW is good by world standards. However, oral health varies with age and among population subgroups.

      Oral health is worse in areas with no access to a fluoridated community water supply.

      Oral Health 2020: A Strategic Framework for Dental Health in NSW contains a summary of key indicators of oral health for children, adults and disadvantaged groups.

    • Introduction: Oral health


      Oral health is an integral component of lifelong health and is much more than the absence of oral disease. Oral health can affect a person's comfort in eating and social interactions, their self-esteem and satisfaction with their appearance.

      A key indicator of the oral health status of a population is the measure of dental caries. In the primary dentition, this is recorded as the number of primary teeth that are decayed (d), missing (m) due to dental caries, or filled (f) because of dental caries. Permanent caries experience (DMFT) is recorded as the number of permanent teeth that are either decayed (D), missing (M) because of dental caries, or filled (F) because of dental caries

      Burden of disease

      In recent years, dental caries was the most prevalent health problem, and periodontal diseases were the fifth most prevalent health problem in Australia. About 90% of all tooth loss can be attributed to these two health problems and, because they are preventable and treatable, most tooth loss is avoidable. In recent decades, factors such as changes in diet, reduced sugar consumption, exposure to fluoride, and changes in disease management have contributed to significant improvements in oral health. Australians in all states and territories enjoy a relatively high standard of oral health. However, this high standard is not equally distributed among different age and social groups.

      Oral health is affected by a complex interplay of social, environmental, and economic factors that extend beyond risk behaviour. Specific population groups, such as refugees and prison inmates, continue to experience extensive oral disease.

      Oral Health 2020: A Strategic Framework for Dental Health in NSW

      The Strategic Framework Oral Health 2020 sets the platform for oral health action in NSW into the next decade. It provides an overview of the oral health status of the population, outlines the goals for oral health services, describes target groups that require focused efforts, and outlines the high level actions that will be pursued to improve the oral health of the population. The Strategic Framework will support the NSW Ministry of Health and Local Health Districts to plan and deliver priority programs tailored to the health needs of the populations at both a state and local level.

      The goals of Oral Health 2020: A Strategic Framework for Dental Health in NSW are to:

      1. Improve access to oral health services in NSW.

      2. Reduce disparities in the oral health status of people in NSW.

      3. Improve the oral health of the NSW population through primary prevention.
