The anatomy of the hamular notch region
Authors: Barker B. C. W. 
Published: May 2009

AbstractIn dental prosthetic practice, a full maxillary denture base is extended over the tuberosity and rests on mucosa overlying the hamular notch, which is the area between hamulus and maxillary tuberosity. Little or no movement occurs in the mucosa here. A dissection of submucosal structures related to the notch revealed variations in arrangement and form which did not conform entirely with textbook descriptions.

Authors: Sutton A. J. , Spratley M. H. 
Published: May 2009

AbstractA simple, robust and relatively inexpensive mechanical digitizer is described which has applications for researchers involved in converting graphical data to digital form. The use of a programmable calculator to re‐orientate landmarks to a standardized baseline is also described.Double determination of a series of points showed the apparatus to have a high degree of precision and accuracy.
Dental practice in South Australia
Authors: Gerke D. C. , Smales R. J. 
Published: May 2009

AbstractThere have been many changes in the provision of dental care in South Australia since about 1970. A comprehensive questionnaire returned by 58 full time general practitioners working in 71 practices revealed that most of the dentists worked a relatively short week and working year. There was evidence of decreased workloads shown by relatively few treatment items being needed for patients, and treatments being completed within a short time.
Effects of prolonged administration of azathioprine on parotid glands of rats: An assessment by light microscopy
Authors: Keys D. W. , Adkins K. F. 
Published: May 2009

AbstractStructural changes induced in parotid glands of rats following prolonged daily administration of 2 mg/kg of azathioprine were studied by light microscopy. Several deleterious effects were consistently observed; these increased in severity as the period of drug administration continued but stopped short of complete destruction of acinar and ductal cells after 56 days. Longer periods of administration did not further increase the extent of cellular damage. Following cessation of drug administration cellular morphology and glandular architecture rapidly returned to normal.
The fluoride content of Melbourne's treated public water
Authors: de Freitas J. F. 
Published: May 2009

AbstractOne hundred and twenty‐one water samples from one hundred different city and suburban outlets in the Melbourne metropolitan area were analysed quantitatively for fluoride concentration. Excluding ten samples, corresponding to a period when the relevant fluoridation equipment was functioning only intermittently, 89 per cent were within the range 0.7 to 1.2 ppm fluoride specified by the Victorian Health Commission, three per cent were greater and eight per cent were below this range.
The personalities of dentists as a factor in the use of nitrous oxide relative analgesia
Authors: Gaffney T. J. , Foenander G. , Reade P. C. , Burrows G. D. 
Published: May 2009

AbstractThe question of whether the use by dentists of a sedation technique, nitrous oxide relative analgesia, is related to tendencies to psychological instability was tested. No correlation was found. The use of this technique was however related to age and number of years since graduation, being more commonly used by the younger and more recent graduates.
Measurement of dimensional stability of elastomeric impression materials by holographic interferometry
Authors: B.Sc.(Hons) W. Mincham. B.D.S.(Hons). , Thurgate S. M. , B.Sc A J. Lewis. 
Published: May 2009

AbstractA technique for measuring changes in the dimensions of elastomeric impression materials is described. The technique involves using holographic interferometry to determine the rate of dimensional change on setting of the materials. The total change in dimension is found by integration with time. The sensitivity of the technique allows accurate determination of these quantities. Holography involves no direct physical contact with the test sample and more than one sample can be tested at the same time under the same conditions.In a preliminary investigation, the technique was applied to several classes of commercially available impression materials. The results are compared with those obtained by other techniques.
Alloys for crown and bridgework
Authors: Brockhurst P. J. , Cannon R. W. S. 
Published: May 2009

Abstract— The requirements of alloys for metal‐ceramic crowns and bridgework are examined. The functional requirements and manipulative behaviour and cost of cheaper alternatives to high gold alloys are discussed.All types used high gold, reduced gold, silver palladium and base metal—appear to function satisfactorily in the mouth. Nickel and beryllium do not appear to be health hazards.Dental laboratory procedures and materials must be chosen to suit the type of alloy employed, although all alloy types appear suitable for crown and bridgework.The cost of alloy must be carefully examined in the context of total cost to the patient, and the use of alternatives to gold alloys in many cases may not warrant the required changes to laboratory procedures, but the saving is real, and can make permanent restorations available to a greater proportion of the community.
Busselton Dental Survey 1978
Authors: Medcalf G. W. 
Published: May 2009

Abstract— In Busselton, Western Australia, 89 per cent of the adult population received a dental examination in 1969. In 1978, 75 per cent of people under age 40 were examined.Comparison between the two survey groups shows increased retention of natural teeth and decrease in denture wearing. The most prevalent treatment need was for calculus removal and oral hygiene instruction.

Authors: Lester Keith S. 
Published: May 2009

Abstract— Westmead Centre is a large teaching hospital of 925 acute treatment beds planned to provide a comprehensive range of general and specialist referral services to the rapidly expanding population of the western suburbs of Sydney. The hospital was conceived in 1968 and opened for patient treatment in 1978.The Dental Clinical School is an integral part of Westmead Centre. The School was planned to provide diagnostic, treatment, recovery, and support facilities. When fully commissioned, it will offer 230 dental chairs, a fully equipped Operating Suite, and extensive laboratory, teaching and research areas. The School is meant to provide clinical undergraduate training for dental students of the University of Sydney and facilities for graduate, postgraduate, and continuing education. At the same time it is to fulfil a general and specialist service role in the Western Metropolitan Health Region.The Dental Clinical School opened for patient treatment in 1980 and accepted its first intake of final year students in 1981. It is anticipated that in 1982 the School will be fully commissioned and making a significant contribution to the dental education and care of the people of New South Wales.
Anterior subgingival fractures: a review of treatment alternatives
Authors: Heithersay G. S. , Moule A. J. 
Published: May 2009

Abstract— The treatment of teeth with subgingival fractures is complicated by the need to maintain a healthy periodontium. In treatment planning for these teeth, the position and the circumferential extent of the fracture are of considerable importance. However, the severity of fracture subgingivally is probably the most important variable influence on treatment planning.In this paper teeth with subgingival fractures are classified into four treatment categories according to the depth of fracture. Treatment alternatives are given for each category and emphasis is given to those procedures which best predispose to a favourable gingival relationship.
Developing a forensic dental code and programme
Authors: Pierce L. , Lindsay J. , Lautenschlager E. P. , Smith E. S. , Harcourt J. K. 
Published: May 2009

AbstractAn attempt was made to develop a computer‐assisted programme to aid in the positive identification of human remains. The first and second generations of a computer code and programme for entering ante‐mortem and post‐mortem records into a computer data bank are discussed. The initial code is presented along with the results following the computer evaluation of 50 record pairs. The self‐evaluating aspects of the programme are discussed and the proposed second generation code is presented. The programme exhibits some promising characteristics but further refinement based on increased data banks is needed.
The heat resistance of a ceramic identification device
Authors: Wilson D. F. , Kolbinson D. 
Published: May 2009

Abstract— Identification of human remains by the teeth is a widely accepted forensic procedure. At present the principle dental technique used for identification of the dead is the post‐mortem comparison method which involves a comparison of post‐mortem dental findings and any available ante‐mortem records.This study describes the results of an in vitro incineration investigation testing the heat resistance qualities of metallic intelligence data encoded on microchips comprising part of the Denlify system of identification. Detailed optical and scanning electron microscopic findings show that despite some alteration when exposed to high temperatures the metallic intelligence data itself remains clearly decipherable after exposure to a temperature of 1000 °C.
Salivary inflammatory exocrinopathy: diagnosis and treatment
Authors: Wiesenfeld David , Ferguson Martin M. 
Published: May 2009

Abstract— Inflammatory exocrinopathy is a disorder most commonly affecting middle‐aged women and is often associated with the presence of a connective tissue disease. The symptoms of salivary gland and lacrimal gland involvement are most prominent. Other terms applied to this disorder include Mikulicz, Gougerot's, Sjögren's, and Sicca syndromes.Reduced salivary function leads to many oral complications. The criteria for the diagnosis of salivary inflammatory exocrinopathy are considered and the oral management discussed.
Mercury vapour associated with amalgam capsule and waste storage
Authors: Burgess V. B. , Makinson O. F. 
Published: May 2009

Abstract— Mercury vapour levels were measured by probe within containers and in close proximity to containers of two types of disposable amalgam capsules, of collections of used capsules in unsealed cartons, and of containers used for storage of amalgam waste. Three types of storage media for amalgam waste were tested and residue from spent capsules weighed.Vapour levels were found to be below recommended safety limits but indicate that these capsule systems require attention as a potential mercury hygiene hazard.
A study of the state and depth of resin penetration into acid‐etched enamel*
Authors: Heng‐Chang Xu , Tong Wang , Humgying Wang 
Published: May 2009

Abstract— The length and cross sectional structure of resin tags formed in the etched enamel of freshly extracted permanent central incisors was studied by floating optical photomicrography and SEM serial photomicrography.Penetration of the etched enamel was enhanced by placing the tooth under vacuum. Floating photomicrography avoided damage to the very fragile resin tags.In general, the tags were 150–200 microns long and in some cases up to 300 microns. They were found to be hollow tubules and not solid rods. The resin tubules had a diameter of 6–7 microns and a wall thickness of 1–1.5 microns.
The use of chemical disinfectants in dental prosthetics
Authors: Kwok W. M. , Ralph W. J. 
Published: May 2009

Abstract— The risk of cross infection in prosthetic dental procedures is a very real one. Normal sterilization and disinfectant procedures, in particular dry and moist heat and some chemical methods, are inappropriate for many treatment procedures.Chemical disinfectants which are normally available in Australia are considered in relation to their compatibility or otherwise with dental prosthetic materials and recommendations for their use are proposed.
Acid‐etching of enamel cavity walls
Authors: Martin F. Elizabeth , Bryant Roland W. 
Published: May 2009

Abstract— The acid‐etched patterns produced on enamel cavity walls and the enamel tooth surface were investigated and the implications of these patterns on cavity preparation for composite resin restorations are discussed.The predominant pattern on enamel cavity walls is of obliquely and longitudinally sectioned prisms. Less commonly, cross‐sectioned prisms, prismless enamel and a rough, pitted appearance are observed. Excessive etching (for example, for four minutes) should be avoided.

Abstract— After the bushfires in Victoria on 16 February 1983, the remains of twenty‐two unidentified people were brought to the Melbourne Coroner's Court for identification.This paper presents the methods adopted by the dental team of the Disaster Victim Identification Task Force.The dental records provided evidence of identity of 14 victims and this highlights the value of dental records in the identification of victims in mass disasters.
Dentinogenesis imperfecta. A new perspective
Authors: Gage J. P. 
Published: May 2009

Abstract— ‐Recent knowledge of collagen biochemistry has increased dramatically with current concepts of its biosynthesis and structure, strengthening the belief that osteogenesis imperfecta and dentinogenesis imperfecta syndromes are basically molecular collagen defects of Type I collagen.The information presently available from studies on dentine collagen indicate a need for the reclassification of the genetic abnormality known as dentinogenesis imperfecta.
An assessment of radiographic methods for the investigation of temporomandibular joint morphology and pathology
Authors: Richards Lindsay C. , Gurner Ian A. 
Published: May 2009

Abstract— The reproducibility and reliability of selected radiographic techniques for the assessment of temporomandibular joint morphology and pathology were investigated in a sample of skulls demonstrating a range of normal and abnormal joint changes. Most methods provided acceptable information about pathological changes of the fossa and condyle.Joint morphology was more difficult to assess, however, with only some methods providing useful information for more than two‐thirds of subjects, emphasizing the need to interpret temporomandibular joint radiographs with great care.
A case: control study of oro‐facial clefts in Western Australia
Authors: Burman Neil T. C. 
Published: May 2009

Abstract— A case: control study was undertaken using all children with oro‐facial clefts born between 1 January 1982 and 14 April 1984 and conceived in Western Australia (WA) — a total of 90 cases and 180 matched controls. Information on all cases and controls was obtained from hospital records and a postal questionnaire. A 92 per cent response rate was obtained from the mothers of affected children.An excess of cleft lip with or without cleft palate (CL(P)) was confirmed for rural Western Australia and reasons for this finding proposed. Further information is presented on maternal age, parity, blood groups, paternal occupation, familial and syndromic clefts, maternal alcohol and cigarette consumption and history of previous miscarriages.
The effects of fractionated megavoltage X‐irradiation on the rat submandibular gland: an assessment by light microscopy and autoradiography
Authors: Savage N.W. , Adkins K. F. , Kruger B. J. 
Published: May 2009

Abstract— Twenty‐four rats were divided into groups that received cumulative dosages of 500, 750 and 1000 rads of fractionated megavoltage X‐irradiation. Animals sacrificed three days post‐irradiation showed marked acinar atrophy but no vascular or ductal changes and isolated areas exhibited more severe damage, predominately vacuolation, apoptosis and total cell destruction. The severity of the changes mirrored the total cumulative dosage. Animals sacrificed 14 days post‐irradiation showed a marked return to pre‐irradiation morphological status.Greater recovery was noted in the 1000 rads dose than in the lower dose groups. A marked increase in vascularity reflected the recovery process. Auto‐radiographic estimations using (3H) leucine supported the morphological changes only in the 1000 rad groups and these showed the least uptake at three days, but by 14 days exhibited the greatest increase—far above the level of control animals. Apoptosis apparently enables the tissues following repair of reversible damage to return to normal cellular activity.
Clinical evaluation of ScotchbondTM: one year results
Authors: Tyas M. J. , Burns G. A. , Byrne P. F. , Cunningham P. J. , Dobson B. C. , Widdop F. T. 
Published: May 2009

AbstractThree hundred and ten non‐undercut cervical abrasion lesions in 83 patients were restored with either the photocured resin based restorative material Silux (175 restorations), its chemically cured counterpart Silar (57 restorations), or glass ionomer (78 restorations). A proprietary dentine bonding agent (chemically cured Scotchbond) was used with Silux and Silar in accordance with the manufacturer's instructions, except that no enamel etching was carried out. Restorations were reviewed after six months and one year. At the one year examination, 25 per cent of Silux, 46 per cent of Silar and 2.5 per cent of the glass ionomer restorations had been lost. There was a progressive increase in marginal discoloration around the resin based restorations.

Authors: Stevens L. 
Published: May 2009

AbstractThe effect of the time between mixing and heating on the expansion of four phosphate bonded investments was investigated. Setting and thermal expansion of the same specimen was measured in a dilatometer. Unexpectedly large differences in setting expansion occurred between the investments. The combined setting and thermal expansion of one investment was affected by the time between mixing and heating.

Authors: Barakat Mohamed M. , Powers John M. 
Published: May 2009

AbstractAdhesive bond strengths of glass ionomer and polycarboxylate cements to human enamel and dentine were measured in vitro on untreated surfaces and on surfaces treated with cement liquid or polyacrylic acid, ferric oxalate, and ferric chloride. The bond strengths of two cements to enamel and dentine were increased by as much as 183 per cent by the use of surface treatments of polyacrylic acid and ferric oxalate.
Poly dental addiction
Authors: Goss Alastair N. 
Published: May 2009

AbstractPoly dental addiction is a psychiatric condition characterized by patients insistently and repeatedly undergoing dental treatment where no organic pathology can be demonstrated and treatment consistently fails to alleviate their symptoms. In this paper two such cases are presented. One patient had multiple extractions and numerous surgical explorations for facial pain and the other had more than thirty dentures constructed over a four‐year period for a burning mouth.
Anisotropic setting expansion of phosphate bonded investment
Authors: Junner R. E. , Stevens L. 
Published: May 2009

AbstractVertical and horizontal setting expansion was measured under different conditions of horizontal restrictive stress provided by a rigid ring with liners and a flexible ring of rubber dam material. Vertical expansion was significantly greater than horizontal expansion in the rigid ring and not significantly different in the flexible ring. The use of a flexible ring offering little or no restriction to horizontal expansion is recommended to reduce mould distortion.

Survey of dental school policies on the management of patients with hepatitis B or AIDS
Authors: Monsour P. A. , Kruger B. J. 
Published: May 2009

AbstractA survey was conducted of dental school Deans in 18 different countries to determine dental school policy on hepatitis B and AIDS. Almost one‐third of the dental schools do not have a policy recommending that clinical staff and students be immunized against hepatitis B. Some 18 dental schools had no procedure for screening patients for hepatitis B, and only 13 per cent of dental schools were actively screening patients in high risk groups for AIDS. The article provides details on the handling of patients who have or are suspected of having hepatitis B or AIDS.
Acquired immunodeficiency syndrome: a perspective*
Authors: Barrett A. P. , Cunningham A. L. 
Published: May 2009

AbstractInfection by the Human T‐Lymphotropic Virus Type III (HTLV‐III) may lead to the devastating and ultimately fatal disease, acquired immunodeficiency syndrome (AIDS). As the virus is transmitted in similar ways to the hepatitis B virus, concern has developed within the dental profession regarding the possibility of clinicians acquiring AIDS through treatment of infected patients. This paper aims to place the significance of HTLV‐III infection to dental practice in perspective.
