Periodontitis
Meaning of periodontitis: For the purposes of this Statement of Principles, periodontitis: (a) means inflammation of the tissues that support the teeth, with periodontal pocketing and destruction of the periodontal ligament or alveolar bone, leading to progressive attachment loss and tooth loss at diseased sites; and (b) includes: (i) aggressive periodontitis; (ii) chronic periodontitis; (iii) necrotising ulcerative periodontitis; (iv) peri-implantitis; and (v) periodontitis as a manifestation of acquired systemic disease; and (c) excludes: (i) abscess of the periodontium; (ii) acute necrotising ulcerative gingivitis; (iii) chronic apical periodontitis; (iv) maxillary and mandibular osteonecrosis; (v) other combined periodontic-endodontic lesions; and (vi) pericoronitis. (3) While periodontitis attracts ICD-10-AM code K05.3, in applying this Statement of Principles the meaning of periodontitis is that given in subsection (2). (4) 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 Edi
Reasonable Hypothesis (RH) — Statement of Principles No. 27 of 2022
At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting periodontitis or death from periodontitis with the circumstances of a person's relevant service:
- (1)having gingivitis involving the affected region of the periodontium for a continuous period of at least the 6 months before the clinical onset of periodontitis;
- (2)having a foreign body in contact with the affected region of the periodontium, on more days than not for a continuous period of at least 6 months before the clinical onset of periodontitis, and where the foreign body has been removed before the clinical onset of periodontitis, then that onset occurred within 4 weeks of removal;
Note: Examples of a foreign body in contact with the periodontium include an osseointegrated implant or dental prosthesis, a removable dental prosthesis and an orthodontic appliance such as a separator or elastic band.
