Empathetic, persistent and female: A snapshot of oral health therapy students in Australia and New Zealand.

INTRODUCTION: Dental therapists, hygienists and oral health therapists constitute up to a third of the dental workforce in Australia and New Zealand. Personality is often explored in health professions to provide insights into traits that are conducive to workforce retention and to assist in planning and training. This study aimed to investigate the current demographic and personality characteristics of oral health students in Australia and New Zealand. MATERIALS AND METHODS: Students in years one to three of all eight undergraduate Bachelor of Oral Health programs in Australia and New Zealand were invited to complete an online survey. The survey measured activities prior to entering into oral health, career intentions and included a personality questionnaire, the Temperament and Character Inventory (TCI). RESULTS: Three quarters of participants (n = 336; 30% response rate; females = 90%) were single, from an urban area and 20-29 years of age. Oral health students overall portrayed high trait levels of Persistence and Cooperativeness. Cluster analysis of TCI traits identified three groups. Groups of students with high Persistence and Cooperativeness tended to be older, were working in non-dental and dental careers prior to their degree and were interested in working in regional areas after graduation. CONCLUSIONS: Students with high levels of persistence and cooperativeness were interested in working in regional areas after graduation, highlighting the importance of industriousness and persistence in overcoming barriers to practicing in regional areas. Further research is warranted to investigate barriers and enablers in recruitment and retention of males in a primarily female dominated profession.

Effectiveness of air polishing as a method of oral prophylaxis in the orthodontic setting: a systematic review protocol.

OBJECTIVE: The objective of this review is to evaluate and synthesize the evidence for the effectiveness of air polishing as a method of oral prophylaxis in the orthodontic setting. INTRODUCTION: Orthodontic treatment to adjust tooth and jaw alignment typically involves wires and bands that trap plaque, thus increasing the risk of developing dental caries. Oral prophylaxis to maintain oral hygiene and prevent tooth and gum disease is typically done through conventional methods or air polishing. There have been no systematic reviews published that evaluate the effectiveness of these prophylactic techniques in this setting. This systematic review will focus on air polishing in the orthodontic setting only. INCLUSION CRITERIA: This review will consider studies with children and adult orthodontic patients undergoing oral prophylaxis as well as prophylaxis of orthodontic appliances. Studies to be included will investigate air polishing with powders compared to any other powder or method of oral prophylaxis. Air polishing versus no intervention will also be included. A range of clinical outcomes will be examined including treatment times and patient comfort as well as adverse effects on orthodontic appliances. METHODS: The JBI approach to critical appraisal, study selection, data extraction, and synthesis will be used. Databases to be searched will include PubMed, Embase, DOSS, and the Cochrane Central Register of Controlled Trials. Unpublished literature will be searched in ProQuest Dissertations and Theses, ClinicalTrials.gov, and Google Scholar. Only studies in English will be considered, with no publication date restriction. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42019143393.

Trajectory of performance: The role of selection criteria on student achievement in a Bachelor of Oral Health programme.

BACKGROUND: To determine whether discontinuing the Undergraduate Medicine and Health Sciences Admissions Test (UMAT) in 2011 for selection and changes to the South Australian Certificate of Education (SACE) requirements in 2012 when the new Australian Tertiary Admissions Rank (ATAR) was introduced impacted on students' accumulative level of achievement and performance in the Bachelor of Oral Health (BOH) programme. METHODS: Board of Examiner's course results for end of year performance were collected for BOH cohorts from 2006 to 2017 (n = 347). Overall performance and achievement level attained were calculated and formed the dependent variables, Performance and Achievement. Group-based trajectory modelling (GBTM) characterised trajectories of yearly academic achievement and the likelihood of each case belonging to the latent group classified as individual group membership. Chi-square (or Fischer's exact) tests were conducted on groups and selected independent variables, using SAS 9.4. RESULTS: A 2-group academic Performance trajectory was selected as Consistent (n = 290; 83.6%) and Inconsistent (n = 57; 16.4%), and Achievement level (credit number) trajectory as Low (n = 154; 44.4%) and High (n = 193; 55.6%). Statistically significant findings in relation to achievement level were found; female students, those who enrolled after UMAT was discontinued, students enrolled since SACE changes, and those who nominated BOH as their first career preference, were more likely to achieve higher grades than their counterparts. CONCLUSION: Discontinuing the UMAT for selection and SACE changes have shown no adverse changes in students' level of achievement in the BOH programme, although enrolling in a course not their first preference was shown to affect performance level.

Variations in Australian dental therapy practice by practitioner and workplace characteristics.

INTRODUCTION: Understanding dental therapy practice across clinical settings is useful for education and service planning. This study assessed if dental therapy service provision varied according to practitioner and workplace characteristics. METHODS: Members of professional associations representing dental therapists (DT) and oral health therapists (OHT) were posted a self-complete survey collecting practitioner and workplace characteristics, together with clinical activity on a self-selected typical day of practice. Differences in service provision according to characteristics were assessed by comparing mean services per patient visit. Negative binomial regression models estimated adjusted ratios (R) of mean services per patient. RESULTS: The response rate was 60.6%. Of practitioners registered as an OHT or a DT, 80.0% (n = 500) were employed in general clinical practice. Nearly one-third of OHT and nearly two-thirds of DT worked in public sector dental services. Patterns of service provision varied significantly according to practice sector and other characteristics. After adjusting for characteristics, relative to private sector, public sector practitioners had higher provision rates of fissure sealants (R = 3.79, 95% confidence interval [95% CI]: 2.84-5.06), restorations (R = 3.78, 95% CI: 2.94-4.86) and deciduous tooth extractions (R = 3.58, 95% CI: 2.60-4.93) per patient visit, and lower provision rates of oral health instruction (R = 0.86, 95% CI: 0.76-0.98), fluoride applications (R = 0.43, 95% CI: 0.33-0.56), scale and cleans (R = 0.39, 95% CI: 0.34-0.45) and periodontal services (R = 0.20, 95% CI: 0.14-0.28) per patient visit. CONCLUSION: Differences in service provision according to sector indicate that OHT and DT adapt to differing patient groups and models of care. Variations may also indicate that barriers to utilising the full scope of practice exist in some settings.

Predicting high achievers in the University of Adelaide, Australia, Bachelor of Oral Health program, 2002-09.

The Bachelor of Oral Health (B.O.H.) commenced at the University of Adelaide in 2002. The degree was formed by combining the Diploma in Dental Therapy and the Diploma and Advanced Diploma in Dental Hygiene. This preliminary study measured the predictive value of the selection criteria against students' academic performance at the end of each enrollment year of the B.O.H. program. Predictive indicators were prior academic achievement (i.e., tertiary entrance ranking [TER], university grade point average, or Special Tertiary Admissions Test scores) and the admission cognitive test score (i.e., Undergraduate Medical Admissions Test [UMAT] and Oral Assessment [OA] ranking). Predictive indicators were compared with the students' level of academic achievement across the three-year program. The aim of this study was to determine if prior academic achievement, cognitive test scores, and oral assessment predicted high level of academic achievement for B.O.H. students. The TER was found to be a strong predictor for academic performance after controlling for age, gender, type of applicant, and student preference in the first year along with older students (>25 years) and a higher UMAT score. Raising the TER cut-off for entry to the program should be considered, along with less emphasis on the OA and UMAT, because such a change would have little impact on achievement and would increase the pool of applicants.

Low-lying isomers and finite temperature behavior of (H2O)6 -.

(H2O)(6) (-) appears as a "magic" number water cluster in (H2O)(n) (-) mass spectra. The structure of the (H2O)(6) (-) isomer dominating the experimental population has been established only recently [N. I. Hammer et al., J. Phys. Chem. A 109, 7896 (2005)], and the most noteworthy characteristic of this isomer is the localization of the excess electron in the vicinity of a double-acceptor monomer. In the present work, we use a quantum Drude model to characterize the low-energy isomers and the finite temperature properties of (H2O)(6) (-). Comparison with ab initio calculations shows that the use of a water model employing distributed polarizabilities and distributed repulsive sites is necessary to correctly reproduce the energy ordering of the low-lying isomers. Both the simulations and the ab initio calculations predict that there are several isomers of (H2O)(6) (-) significantly lower in energy than the experimentally observed species, suggesting that the experimental distribution is far from equilibrium.

Determinants of surgical site infection after breast biopsy.

BACKGROUND: Surgical site infections (SSI) following clean and clean-contaminated ambulatory surgery at Bon Secours Cottage Health Services are monitored utilizing a postdischarge surveillance form in addition to traditional surveillance. From January 2000 to December 2002, the clean procedure SSI rate was 0.73% (31/4266) versus 1.58% (15/950) for breast biopsy, P = .04. A case-control study was performed to identify risk factors for infection. METHODS: A case patient was identified as any patient having an ambulatory breast biopsy from January 2000 to December 2002 with SSI identified by the Centers for Disease Control and Prevention (CDC) definition of nosocomial infection. For each case patient, 3 randomly selected control patients were matched by date and procedure. RESULTS: Factors significantly associated with the development of SSI were duration of surgery (case mean, 71.7 minutes vs control mean, 34.7 minutes, P < .01) and presence of surgical drains (26.7% of cases vs 6.7% of controls, P = .04). Factors determined not to be associated with SSI were obesity (P = .88) and preoperative needle localization (P = .88). CONCLUSIONS: We conclude that there is a significant difference between the breast biopsy infection rate and the clean procedure infection rate in ambulatory surgery. Duration of surgery and presence of surgical drains were associated with increased infection rate.
