The aim of this umbrella review was to collate and appraise the evidence base regarding modifiable risk factors for the prevention of oral diseases to inform the update of the Oral Health Messages for Australia. Eleven questions related to modifiable risk factors and dental disease were investigated. Electronic databases (Medline, Embase and PubMed) were searched from January 2010 to October 2022. Systematic reviews evaluating interventions/exposures in healthy subjects from high-income countries, where Westernized practices, oral health promotion and healthcare systems are similar to Australia, were included. Quality appraisal of included systematic reviews was guided by the AMSTAR tool. Of the 3637 articles identified, 29 articles met eligibility criteria. High-quality systematic reviews were identified for questions relating to diet, infant feeding, dental check-ups and oral hygiene. Free sugars consumption above 5% of energy intake, infrequent toothbrushing, smoking/vaping and alcohol intake were consistently associated with poorer oral health outcomes. Breastfeeding up to the age of 24 months was not associated with an increased risk of early childhood caries. The use of interdental cleaning devices and mouthguards during contact sports are likely to be effective in preventing dental disease.

There is ample published literature regarding the technical aspects of restoring root-filled teeth, but little concerning the biological impacts, consequences, and criteria for the selection of direct restorative materials following endodontic treatment. The provision of an effective coronal seal in addition to a sound root filling is known to be important in the prevention of root canal infection. This review seeks to explore the evidence concerning the selection of dental materials in the restoration of root-filled teeth, specifically with a close examination of the properties of commonly used materials as orifice barriers. © 2023 Australian Dental Association.

What is the rate of burnout amongst Australian dentists?

A treating medical practitioner would be automatically required to make a mandatory report for health impairment to the Dental Board of Australia or Ahpra if they diagnosed a dental practitioner with depression.

Risky or hazardous alcohol consumption was associated with dental practitioners who were:

Which of the following statements is TRUE regarding the rates of mental health illness in Australian dental practitioners, doctors and the general community?

Which of the following statements is NOT TRUE:

Tooth autotransplantation is the technique of transplanting embedded, impacted or erupted teeth from one site into another in the same individual. It is relatively common for the anterior segment of the mouth to be affected by traumatic tooth injuries, impacted and/or congenitally missing permanent teeth. Autotransplantation of teeth into the anterior dental arch can provide unrivalled biological solutions when such issues arise in this critical aesthetic zone, particularly for adolescent patients. The combination of meticulous pre-surgical assessment, synergistic interdisciplinary collaboration and carefully performed anterior tooth autotransplantation has been demonstrated to achieve impressive outcomes, with respect to both transplant survival and clinical success. © 2023 Australian Dental Association.
