Antibiotic resistance is a well-established global public health crisis, with the use and misuse of antibiotics being the principal cause of bacterial resistance. Studies in both Australia and overseas have demonstrated that the dental prescribing of antibiotics is increasing, and that dentists tend to prescribe antibiotics unnecessarily and for incorrect clinical indications. Dental practitioners in Australia also prefer to prescribe moderate to broad spectrum antibacterial agents and make some inappropriate antibiotic prescribing choices...

BACKGROUND: Dento-maxillofacial Radiology (DMFR) is comprised of the smallest cohort of specialists in Australia. A survey was undertaken to assess awareness of DMFR; radiology reporting and referring protocols; as well as dental practitioners' satisfaction with their radiology reporting arrangements. METHODS: An original online survey created using Checkbox†, was sent to dental practitioners. The survey was promoted on Australian-based dental Facebook forums and emailed to targeted members via Australian professional dental associations...

BACKGROUND: This study aimed to fabricate a denture base resin (DBR) containing phytoncide microcapsules (PTMCs) and determine the mechanical properties of the resin and antifungal activity. METHODS: Fifty-four heat cured rectangular DBR specimens (64 x 10 x 3.3 ± 0.2 mm) containing nine concentrations of PTMC between 0 - 5% (wt/wt) were fabricated and subjected to a three-point bending test. A phytoncide release bioassay was developed using DBR containing 0% and 2...

BACKGROUND: Oral and dental disease is a major cause of long-term morbidity following allogeneic blood and marrow transplantation (Allo-BMT). This study aimed to describe the extent and range of oral and dental complications in BMT recipients, and to identify gaps in service provision provided to this high-risk group. METHODS: Participants were Allo-BMT recipients, aged >18years, and received transplants between 2000-2012 in NSW. They completed seven surveys, the purpose-designed Sydney Post-BMT Study survey and six other validated instruments...

BACKGROUND: Developmental hypomineralized lesions of enamel (DHL) may represent a significant caries-risk factor. The aim of this study was to determine the association between carious lesion severity and DHL in 6- to 12-year-old schoolchildren from Melbourne, Australia. METHODS: The sample was derived from randomly selected schools in inner Melbourne. A full dental examination was performed at the school. Socio-demographic data, caries experience (DMFT/dmft/ICDAS II) and the consequences of untreated carious lesions (PUFA/pufa) were measured...

BACKGROUND: Previous research has found dental practitioners at elevated risk of complaint compared with other health professions. This study aimed to describe the frequency, nature, and risk factors for complaints involving dental practitioners. METHODS: We assembled a national dataset of complaints about registered health practitioners in Australia between January 2011 and December 2016. We classified complaints into 22 issues across three domains: health, performance, and conduct...

BACKGROUND: The aim of this study was to develop and evaluate a method for synthesizing a stable suspension of hydroxyapatite nanoparticles and to test its efficacy for remineralizing carious enamel lesions. METHODS: Hydroxyapatite (HA) particles were synthesized using wet-chemistry. Synthesized particles were introduced into a high-pressure homogenizer (5-10 homogenization passes at 15,000 psi) in the presence of different stabilizers. Size and distribution of the resultant particles were determined using dynamic-laser-scattering (DLS)...

The belief that a woman's dental health is likely to deteriorate through having children remains common and may originate from the old wives' tale "a tooth per child". As recently as 2005, about 1 in 5 US mothers believed this.1 Epidemiological studies have suggested an association between parity (the number of times a women has given birth) and tooth loss,2-5 and parity and periodontal attachment loss,6 but none has determined whether this association is causal. A number of studies have reported greater severity and extent of gingival inflammation during pregnancy...

BACKGROUND: Literature has shown dentists tend to overprescribe antibiotics and do not always prescribe in accordance with recommended guidelines. Unnecessary prescribing is one major factor that contributes to the development of antibiotic resistance. The aim of the present study was to assess the antibacterial prescribing patterns of dentists in Australia from 2013 to 2016. METHODS: Data on dental antibacterial prescriptions dispensed under the Pharmaceutical Benefits Scheme (PBS) from 2013 to 2016 was accessed and prescribing trends analysed...

This study aimed to gain insight into common practices of Australian prosthodontists when placing a post in an endodontically treated tooth (ETT). A 17-question open- and closed- format questionnaire was sent to registered Australian prosthodontists. The response rate was 55% (n=95). The majority of respondents indicated the purpose of a post was to retain a core (n=94, 99%). The decision to place a post is affected by the quantity of remaining tooth structure (n=91, 96%) and the definitive restoration (n=68, 72%)...

BACKGROUND: To evaluate the effect of distilled water, ethylenediaminetetraacetic acid (EDTA), phosphoric acid and maleic acid on Biodentine regarding surface topography, microhardness and push-out bond strength (POBS). METHODS: Fifty-two cylindrical shaped Biodentine specimens were divided into groups: control (distilled water); EDTA (17% EDTA); PA (37% phosphoric acid); and MA (7% maleic acid). Surfaces were evaluated by topographic analysis and Vickers microhardness test...

BACKGROUND: The aims of this study were to evaluate the microbiological trends in severe odontogenic infections requiring hospital admission in the South Australian Oral and Maxillofacial Surgery Unit. Rates of antibiotic resistance to empirical antibiotic regimens were determined to quantify the clinical implications of antibiotic-resistant odontogenic infections. METHODS: A retrospective case audit was performed on all odontogenic infections admitted to the Royal Adelaide Hospital over a 9-year period...

BACKGROUND: To evaluate changes in xerostomia status, salivary characteristics and gland volumes 2 years following radiotherapy in nasopharyngeal carcinoma patients. METHODS: Xerostomia scores, salivary flow rates, pH and buffering capacity were measured at pre-radiotherapy, mid-radiotherapy, 2 weeks, 3 months and 2 years post-radiotherapy. Salivary gland volumes and their correlation with radiation dose were also assessed. RESULTS: Mean radiation dose to oral cavity, parotid and submandibular glands (SMG) was 44...

BACKGROUND: The aim of this study was to investigate for the first time the histological response of human periodontium to mineral trioxide aggregate (MTA) and Biodentine. METHODS: Six patients scheduled for implant full-arch rehabilitation were randomly assigned to one of the two test groups: MTA or Biodentine treatment. For each patient, two teeth scheduled for strategic extraction were randomly assigned either to the test or to the control treatment. A lateral perforation was drilled on the root and either repaired with MTA/Biodentine or filled with gutta-percha(control)...

BACKGROUND: This study aimed to examine if specific micronutrients were associated with periodontal disease using data from the US National Health and Nutrition Examination Survey (NHANES) from 2011 to 2014. METHODS: Participants who were aged 30 years or more and received complete periodontal examinations were included. Regression analyses were performed to determine associations of variables of interest with periodontal disease. RESULTS: Data of 6415 NHANES participants were included in the analysis...

BACKGROUND: Tooth discolouration could occur due to bacterial contamination in traumatized teeth. Hydrogen peroxide is the commonly used bleaching agent. However, due to concerns over safety, alternative bleaching regimes such as sodium perborate (S) and thiourea-hydrogen peroxide (T) have been investigated. METHODS: Apices resected and pulp extirpated 99 premolars were divided into two groups. Group 1 and 2 was injected with blood and blood/bacteria, stored anaerobically for 35 days...
