and\n\n(b)          commencing at least 5 years before the clinical worsening of dental pulp and periapical disease; and\n\nif smoking has ceased before the clinical worsening of dental pulp and periapical disease, then that worsening occurred within 10 years of cessation;\n\nNote: one pack-year is defined in the Schedule 1 - Dictionary.\n\n(16)      having diabetes mellitus at the time of the clinical worsening of dental pulp and periapical disease;\n\n(17)      having scleroderma or Sjögren syndrome at the time of the clinical worsening of dental pulp and periapical disease;\n\n(18)      having osteonecrosis of the jaw involving the affected tooth at the time of the clinical worsening of dental pulp and periapical disease;\n\nNote: Examples of causes of osteonecrosis of the jaw include sickle-cell disorder and medication-related osteonecrosis.\n\n(19)      inability to obtain appropriate clinical management for dental pulp and periapical disease.\n\n10           Relationship to service\n\n(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.\n\n(2)          The factors set out in subsections 9(10) to 9(19) apply only to material contribution to, or aggravation of, dental pulp and periapical disease where the person's dental pulp and periapical disease was suffered or contracted before or during (but did not arise out of) the person's relevant service.\n\n11           Factors referring to an injury or disease covered by another Statement of Principles\n\nIn this Statement of Principles:\n\n(1)          if a factor referred to in section 9 applies in relation to a person; and\n\n(2)          that factor refers to an injury or disease in respect of which a Statement of Principles has been determined under subsection 196B(2) of the VEA;\n\nthen 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.\n\n \n\n \n\nSchedule 1 - Dictionary  \n\nNote:               See Section 6\n\n1               Definitions\n\nIn this instrument:\n\n                                dental concussion means an injury of the tooth-supporting structures without increased mobility or displacement of the tooth but with pain on percussion.\n\n                               dental pulp and periapical disease—see subsection 7(2).\n\n                               luxation means an injury of the tooth-supporting structures with increased mobility or displacement of the tooth.\n\n                               MRCA means the Military Rehabilitation and Compensation Act 2004.\n\n                               non-invasive dental or orthodontic procedure means the therapeutic application of a chemical substance, heat or cold, or a physical force to the surface of the teeth, during the course of dental or orthodontic treatment;\n\nNote: Examples of a non-invasive dental or orthodontic procedure include:\n\n(i) acid etching;\n\n(ii) dehydration;\n\n(iii) in-office tooth bleaching;\n\n(iv) orthodontic treatment;\n\n(v) restorative procedures such as cavity preparation, crown preparation and curing of resins during provisional restorations; and\n\n(vi) vibration or mechanical irritation.\n\n                               one pack-year means the amount of tobacco consumed in smoking 20 cigarettes per day for a period of 1 year, or an equivalent amount of tobacco products.\n\nNote 1: An equivalent amount of tobacco products is 7,300 grams of smoking tobacco by weight, either in cigarettes, pipe tobacco or cigars, or a combination of same. For pipe tobacco, cigars or combinations of multiple tobacco types, 1 gram of tobacco is considered to be equal to one cigarette.\n\nNote 2: Pack-years are calculated by dividing the number of cigarettes smoked per day by 20 and multiplying this number by the number of years the person has smoked. For example, smoking 10 cigarettes per day for 10 years is equal to 5 pack-years, and smoking 40 cigarettes per day for 10 years is equal to 20 pack-years.\n\n                               periapical abscess means a destructive process in the bony and ligamentous supporting tissues of the apices of the teeth resulting in a localised collection of pus.

Periapical cyst is also known as radicular or odontogenic cyst.\n\n                               periapical periodontitis means an acute or chronic destructive inflammatory disease of the bony and ligamentous supporting tissues of the apices of the teeth. The inflammation can be limited to the periodontal ligament, but can also involve the root cementum, dentin and alveolar bone. Periapical periodontitis is also known as apical periodontitis.\n\n                               pulpitis means acute or chronic, reversible or irreversible inflammation of the dental pulp.\n\n                               relevant service means:\n\n(a)          operational service under the VEA;\n\n(b)          peacekeeping service under the VEA;\n\n(c)          hazardous service under the VEA;\n\n(d)          British nuclear test defence service under the VEA;\n\n(e)          warlike service under the MRCA; or\n\n(f)           non-warlike service under the MRCA.\n\nNote: MRCA and VEA are also defined in the Schedule 1 - Dictionary.\n\n                               surgery means dental surgery, orthodontic surgery or maxillofacial surgery.\n\n                               terminal event means the proximate or ultimate cause of death and includes the following:\n\n(a)           pneumonia;\n\n(b)           respiratory failure;\n\n(c)           cardiac arrest;\n\n(d)           circulatory failure; or\n\n(e)           cessation of brain function.\n\n                               trauma involving the affected tooth means a blunt or penetrating injury resulting in:\n\n(a)          avulsion and subsequent replantation of the affected tooth;\n\n(b)          dental concussion;\n\n(c)          disruption or fracture of the periodontium in the region of the affected tooth;\n\n(d)          fracture or crack of the affected tooth; or\n\n(e)          luxation of the affected tooth.\n\nNote: dental concussion and luxation are also defined in the Schedule 1 - Dictionary.\n\n                               VEA means the Veterans' Entitlements Act 1986.\n\n \n\n \n","sortOrder":0}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
