REVIEW

Dentinal hypersensitivity: a review Tooth sensitivity is a very common clinical presentation which can cause considerable concern for patients. This review considers the aetiology, incidence and management of dentinal hypersensitivity.

ADRF RESEARCH REPORT

Prevalence and side preference for tooth grinding in twins Estimates of the prevalence of tooth grinding in children range considerably, reflecting different methods of recording. The main aims of this study were to determine the prevalence of tooth grinding in monozygotic (MZ) and dizygotic (DZ) twin pairs by assessing wear faceting on the primary canines, and to compare the faceting on the right and left to determine whether children have a side preference for grinding.

SCIENTIFIC ARTICLES

Maxillofacial trauma in major trauma patients Trauma has been identified as a major public health problem in Australia. Maxillofacial trauma constitutes a significant proportion of trauma, although epidemiological studies in Australia are few. The purpose of this study was to assess the prevalence and the epidemiological pattern of maxillofacial trauma occurring in major trauma patients.	FN Shahim P Cameron JJ McNeil
Hospitalization of Western Australian children for oral health related conditions: a 5–8 year follow-up This study investigated in-patient oral health care provision for children under 18 years of age in Western Australia.	E Kruger K Dyson M Tennant
Ion uptake into demineralized dentine from glass ionomer cement following pretreatment with silver fluoride and potassium iodide Diamine silver fluoride (Ag(NH3)2F), referred to as AgF, has been shown to provide a pronounced antimicrobial action against caries. The purpose of this study was to determine if a prior application of silver fluoride and potassium iodine to demineralized dentine affected the uptake of strontium and fluoride from a glass ionomer cement restoration.

Fluoride content of still bottled water in Australia Recently there has been a considerable increase in the consumption of bottled water in Australia. Overseas studies have found the fluoride levels in many bottled waters are well below levels considered optimal for preventing dental caries. This raises the concern that if bottled water is regularly consumed an effective means of preventing dental caries is unavailable. The aim of this study was to determine the fluoride concentration in 10 popular brands of still bottled water currently sold in Australia.	NJ Cochrane S Saranathan MV Morgan SG Dashper
Dissolution of porcine incisor pulps in sodium hypochlorite solutions of varying compositions and concentrations The solubility of dental pulp tissue in sodium hypochlorite has been extensively investigated but results have been inconsistent; due most likely to variations in experimental design, the volume and/or rate of replenishment of the solutions used and the nature of the tissues assessed. The purpose of this study was to perform new solubility assessments, comparing Milton with new TGA approved products, Hypochlor 1% and Hypochlor 4% forte, and with a domestic bleach containing surfactant (White King).

Comparison of microshear bond strengths of four self-etching bonding systems to enamel using two test methods Recent advances in enamel and dentine adhesive technology have resulted in the emergence of many new adhesive systems. Self-etching bonding systems do not require a separate etching step and the newest systems are the “all-in-one” systems which combine etching, priming and bonding into a single application. This study reports laboratory enamel microshear bond strengths of a self-etching priming and three all-in-one systems and also evaluates two different microshear bond test methods.

Ex vivo evaluation of the ability of four different electronic apex locators to determine the working length in teeth with various foramen diameters The aim of this ex vivo study was to evaluate the accuracy of four electronic apex locators (EALs) to determine the working length in teeth with various foramen diameters.

CASE REPORT

The use of a dental implant as an abutment in three unit implant-tooth supported fixed partial denture: a case report and 32 month follow-up The combined use of dental implants and teeth as abutments in fixed partial dentures may offer advantages to both patients and practitioners in certain clinical situations. An implant-tooth retained prosthesis may reduce surgical intervention and cost to the patient. It may also mean that anatomical restrictions to the provision of an implant-retained fixed prosthesis may be overcome. In this case report, the steps in provision of a three unit implant-to-tooth fixed partial denture are described and the treatment planning and prognosis of a restoration of this type are discussed.

DATA WATCH

Intra-oral distribution of caries in South Australian children The Child Dental Health Survey (CDHS), a national surveillance survey of child oral health, is one of the longest running national health data collections in Australia. Commencing in 1977 under the auspices of the then Commonwealth Department of Health, the annual survey has documented an appreciable improvement in Australian children’s caries experience.

Prevention and management of dental decay in the preschool child Scottish Intercollegiate Guideline Network. No. 83. Prevention and management of dental decay in the preschool child. Edinburgh: Scottish Intercollegiate Guideline Network (SIGN). ISBN 1 899893 44X 2005. The guideline addresses effective strategies for preventing and managing dental decay in the preschool child. The nature of dental decay, its diagnosis and its epidemiology are reviewed. Methods for prevention and management of the disease at an individual and population level are reviewed and identification of children at increased risk of developing dental disease is discussed.
