1. Name This is the Statement of Principles concerning tooth decay (dental caries) (Balance of Probabilities) (No.75 of 2024). 1. Commencement This instrument commences on 19 November 2024. 1. Authority This instrument is made under subsection 196B(3) of the Veterans' Entitlements Act 1986. 1. Repeal The Statement of Principles concerning dental caries (Balance of Probabilities) (No. 123 of 2015) (Federal Register of Legislation No. F2015L01676) made under subsection 196B(3) of the VEA is repealed. 1. Application This instrument applies to a claim to which section 120B of the VEA or section 339 of the Military Rehabilitation and Compensation Act 2004 applies. 1. Definitions The terms defined in the Schedule 1 - Dictionary have the meaning given when used in this instrument. 1. Kind of injury, disease or death to which this Statement of Principles relates 1. This Statement of Principles is about tooth decay (dental caries) and death from tooth decay (dental caries). Meaning of tooth decay (dental caries) 1. For the purposes of this Statement of Principles, tooth decay (dental caries): 1. means the localised destruction of dental hard tissues (enamel, cementum or dentine) by dental plaque, leading to demineralisation or cavity formation; and 2. excludes: 1. dental pulp and periapical disease; 2. tooth loss; and 3. tooth wear. Note: Tooth decay (dental caries) can involve any part of the tooth, including the crown, neck or root. 1. While tooth decay (dental caries) attracts ICD‑10‑AM codes K02.0, K02.1, K02.2, K02.3, K02.5, K02.8 and K02.9, in applying this Statement of Principles the meaning of tooth decay (dental caries) is that given in subsection (2). 2. For subsection (3), a reference to an ICD-10-AM code is a reference to the code assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM), Tenth Edition, effective date of 1 July 2017, copyrighted by the Independent Hospital Pricing Authority, ISBN 978-1-76007-296-4. Death from tooth decay (dental caries) 1. For the purposes of this Statement of Principles, tooth decay (dental caries), in relation to a person, includes death from a terminal event or condition that was contributed to by the person's tooth decay (dental caries). Note: terminal event is defined in the Schedule 1 – Dictionary. 1. Basis for determining the factors On the sound medical‑scientific evidence available, the Repatriation Medical Authority is of the view that it is more probable than not that tooth decay (dental caries) and death from tooth decay (dental caries) can be related to relevant service rendered by veterans or members of the Forces under the VEA, or members under the MRCA. Note: MRCA, relevant service and VEA are defined in the Schedule 1 – Dictionary. 1. Factors that must exist At least one of the following factors must exist before it can be said that, on the balance of probabilities, tooth decay (dental caries) or death from tooth decay (dental caries) is connected with the circumstances of a person's relevant service: 1. having tooth wear involving the affected tooth for at least the 3 months before clinical onset; 2. having loss of gum tissue from the base of the affected tooth, with exposure of the root surface (gingival recession), for at least the 3 months before clinical onset of root surface caries; 3. having a course of therapeutic radiation to the head or neck, where the affected tooth was in the field of radiation, within the 2 years before clinical onset or clinical worsening; 4. having dry mouth resulting from severely reduced saliva flow (xerostomia) for a continuous period of at least 3 months, within the 2 years before clinical onset or clinical worsening; Note: Xerostomia can result from surgery, Sjögren syndrome, or a wide variety of drugs, including anticholinergics, tricyclic antidepressants and amphetamines. 1. inability to obtain therapeutic exposure to fluoride to the teeth in at least one of the following forms: 1. fluoridated drinking water with a fluoride concentration of at least 0.5 milligrams per litre; 2. fluoridated toothpaste with a fluoride concentration of at least 1,000 parts per million; 3. liquid, tablet or lozenge formulation; on more days than not for a continuous period of at least 1 year, within the 5 years before clinical onset or clinical worsening; 1. consuming foods, beverages or other products containing sugar or processed starch: 1. continuously over a period of at least 6 hours per day; or 2. on at least 10 separate occasions per day with more than 30 minutes between exposures; and for a continuous period of at least 3 months, within the 2 years before clinical onset or clinical worsening; 1. having smoked at least 6 pack-years before clinical onset or clinical worsening, and where smoking has ceased, clinical onset or clinical worsening occurred within 5 years of cessation; Note: one pack-year is defined in the Schedule 1 - Dictionary. 1. the use of chewing tobacco: 1. on more days than not; and 2. for at least 10 years before clinical onset or clinical worsening; and where the use of chewing tobacco has ceased, clinical onset or clinical worsening occurred within 5 years of cessation; 1. inability to perform effective personal cleaning of the affected tooth for a continuous period of at least 3 months, within the 2 years before clinical onset or clinical worsening; Note: Examples of circumstances where there can be an inability to perform effective personal cleaning of the affected tooth include active combat, the presence of a physical disability or a severe mental disability affecting self-care, and the presence of a fixed orthodontic appliance. 1. inability to access preventive professional dental care at least every 15 months, within the 5 years before clinical onset or clinical worsening; 2. inability to obtain appropriate clinical management for tooth decay (dental caries) before clinical worsening. 1. Relationship to service 1. The existence in a person of any factor referred to in section 9, must be related to the relevant service rendered by the person. 2. The clinical worsening aspects of factors in Section 9 apply only to material contribution to, or aggravation of, tooth decay (dental caries) where the person's tooth decay (dental caries) was suffered or contracted before or during (but did not arise out of) the person's relevant service. 2. Factors referring to an injury or disease covered by another Statement of Principles In this Statement of Principles: 1. if a factor referred to in section 9 applies in relation to a person; and 2. that factor refers to an injury or disease in respect of which a Statement of Principles has been determined under subsection 196B(3) of the VEA; then the factors in that Statement of Principles apply in accordance with the terms of that Statement of Principles as in force from time to time.
