March 2006 - Volume 51 Number 1REVIEWCryotherapy for treatment of oral lesions
Cryotherapy is the deliberate destruction of tissue by application of extreme cold. It is well received by patients due to a relative lack of discomfort, the absence of bleeding and minimal to no scarring after healing. It has many applications in oral medicine and clinical oral pathology, and is extremely useful in patients for whom surgery is contra-indicated due to either age or medical history. In this paper we outline the principles, mechanisms of action, and current applications of cryotherapy in the treatment of oral lesions, and present some clinical cases.

ADRF RESEARCH REPORTSDental therapy in Western Australia: profile and perceptions of the workforce
In 2002, the Centre for Rural and Remote Oral Health (CRROH) completed a rural oral health workforce survey which indicated that a high number of therapists, although registered, were not working as therapists. The aim of the present study was to develop a profile of the dental therapy workforce and analyse the perceptions of therapists.

| Guided self diagnosis: an innovative approach to triage for emergency dental care
The basic model of triage, developed more than 200 years ago by the French, is based on categorization of patient needs and thus the urgency and time required for care. This model in various forms is used in most hospitals throughout the world.

M Tennant | Epidemiological analysis of tongue cancer in South Australia for the 24-year period, 1977–2001
Tongue cancer (141 ICD-9) is the most common intra-oral malignancy in Western countries. In recent decades, reported tongue cancer incidence and mortality rates have increased both in Europe and in the United States, whilst survival has not improved. This study aimed to determine the epidemiology and survival trends of tongue cancer in South Australia over the 24-year period from 1977 to 2001.

SCIENTIFIC ARTICLES The comprehensive evaluation of temporomandibular disorders seen in rheumatoid arthritis
We studied clinical signs and symptoms of temporomandibular disorders and radiological changes in the temporomandibular joint from patients with rheumatoid arthritis (RA) compared to patients with myofascial pain dysfunction of the temporomandibular system and control patients to evaluate clinical and radiological relationships.

| Accessing government subsidized specialist orthodontic services in Western Australia
In Australia there is growing demand for dental services. This leads to more pressure on the oral health service providers, and in particular government subsidized dental care. Against this backdrop it is important that government dental services (rationed to health care cardholders) are provided equitably on a basis of need, not access. The primary hypothesis investigated in this study was that there would be an even distribution of patients referred for government subsidized orthodontic care across Western Australia when regionally adjusted for socio-economic status.

M Tennant | The influence of the leaf gauge and anterior jig on jaw muscle electromyography and condylar head displacement: a pilot study
A leaf gauge and an anterior jig may be used to assist the recording of a reproducible jaw position for restorative and prosthodontic treatment. This study investigated possible condylar displacement using an opto-electronic jaw-tracking device and a leaf gauge or anterior jig. The effect of a leaf gauge and anterior jig on jaw muscle electromyography was also examined.

IJ Klineberg | The effect of silver fluoride and potassium iodide on the bond strength of auto cure glass ionomer cement to dentine
Diamine silver fluoride (Ag(NH3)2F), referred to as AgF, has been shown to reduce the incidence of caries in primary dentitions. The clinical application of this material has been limited by staining associated with both teeth and restorative materials. The application of potassium iodide (KI) after AgF eliminates stain formation. There is a lack of information as to how the addition of AgF followed by KI may affect the bond strength to dentine. The purpose of this study was to compare the bond strengths of auto cure glass ionomer cement to dentine surfaces that had been treated with AgF and KI and without treatment.

Mulyani | Factors influencing recent dental graduates’ location and sector of employment in Victoria
Recruitment and retention of dentists in the public sector and rural areas in Victoria has become increasingly difficult in recent years. There are little available data on the factors that influence the sector and location of practice of new dental graduates. The objective of this study was to investigate the factors considered by new graduates in determining the location and sector of employment after graduation, and influencing any early changes in career path.

In recent years, glass fibres have been used to strengthen denture base resins. A major difficulty in using reinforcing fibres with multiphase acrylic resins, such as powder liquid resins, is inadequate impregnation of the fibres with the resin.

KHR Ott | Methods of determining the relationship of the mandibular canal and third molars: a survey of Australian oral and maxillofacial surgeons
Surgical extraction of third molars is one of the most common oral and maxillofacial surgical procedures performed and may have a number of associated complications. One of these complications is inferior alveolar nerve (IAN) dysaesthesia or impairment of sensory perception (including paraesthesia and/or anaesthesia). Previous studies assume that most clinicians use various combinations of nine radiologic criteria on anoramic radiographs as indicators of the relationship and, therefore, predictors of the risk of postoperative dysaesthesia. Our study assessed both the current radiologic modalities and assessment criteria used by Australian oral and maxillofacial surgeons when determining the proximity of mandibular canal to third molars.

M Tennant | Analysis of the acute postoperative pain experience following oral surgery: identification of ‘unaffected’, ‘disabled’ and ‘depressed, anxious and disabled’ patient clusters
Pain is defined as both a sensory and an emotional experience. Acute postoperative tooth extraction pain is assessed and treated as a physiological (sensory) pain while chronic pain is a biopsychosocial problem. The purpose of this study was to assess whether psychological and social changes occur in the acute pain state.

CASE REPORTFailure to obtain adequate anaesthesia associated with a bifid mandibular canal: a case report
The inferior alveolar nerve (IAN) block is the most common method for obtaining mandibular anaesthesia in dental practice but it is estimated to have a success rate of only 80 to 85 per cent. Causes of failure include problems with operator technique and anatomical variation between individuals. This case report involves a patient who received IAN blocks on two separate occasions that resulted in only partial anaesthesia of the ipsilateral side of the mandible.

DATA WATCHPractice profiles of Australian private general dental practitioners
In Australia, the vast majority of dental practitioners are in the private sector (83 per cent). The provision of oral health services is dominated by general practitioners (85 per cent), with a small percentage of practitioners in specialist and restricted practice (12 per cent), and the remainder in areas such as administration, teaching and research. This paper describes the profile of patients and their presenting conditions among private general dental practitioners in 2003–2004.
