In this instrument:
                                  dental concussion means an injury of the tooth-supporting structures without increased mobility or displacement of the tooth but with pain on percussion.
                               dental pulp and periapical disease—see subsection 7(2).
                                  luxation means an injury of the tooth-supporting structures with increased mobility or displacement of the tooth.
                                  MRCA means the Military Rehabilitation and Compensation Act 2004.
                               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;
Note: Examples of a non-invasive dental or orthodontic procedure include:
           (i) acid etching;
           (ii) dehydration;
           (iii) in-office tooth bleaching;
           (iv) orthodontic treatment;
           (v) restorative procedures such as cavity preparation, crown preparation and curing of resins during provisional restorations; and
           (vi) vibration or mechanical irritation.
                               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.
         Note 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.
         Note 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.
                               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. It can be acute or chronic, and may be symptomatic or asymptomatic. Periapical abscess is also known as endodontic or dentoalveolar abscess.
                               periapical cyst means an epithelium-lined periodontal cyst involving the apex of a devitalised tooth. Periapical cyst is also known as radicular or odontogenic cyst.
                               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.
                                  pulpitis means acute or chronic, reversible or irreversible inflammation of the dental pulp.
                                  relevant service means:
         (a)          eligible war service (other than operational service) under the VEA;
         (b)          defence service (other than hazardous service and British nuclear test defence service) under the VEA; or
         (c)          peacetime service under the MRCA.
