Oral Health Research Connect - May 2026 Mancuso, Edoardo; Miletic, Vesna • Current trends in adhesive cementation: A research-based analysis of materials and clinical protocols- Dr Edoardo Mancuso The rapid evolution of restorative dentistry has introduced an extensive array of materials boasting superior mechanical and aesthetic properties. However, this progress necessitates a parallel advancement in adhesive systems and cementation protocols. With the market currently saturated by a plethora of luting options, clinicians frequently encounter challenges in selecting the most appropriate material for specific clinical scenarios. This presentation aims to provide a comprehensive, literature-based framework for the cementation of prosthodontic restorations, with a specific focus on substrate-driven selection. Recognizing that no universal "gold standard" protocol exists, as the properties of the abutment and the restorative material vary significantly, this session emphasizes the necessity of individualized clinical considerations for each case. Dr Edoardo Mancuso will analyze recent research and emerging materials, offering evidence-based guidelines to bridge the gap between laboratory data and chairside application. By synthesizing contemporary research with clinical technique, this session aims to guide clinicians in precise decision-making to enhance the predictability and success of adhesive restorations in routine practice. • Research priorities across academic career pathways in Sydney Dental School - Professor Vesna Miletic The OHRC invites Dr Vesna Miletic, recently re-appointed Director of Academic Career Development, for a discussion on how academics in Sydney Dental School can prioritise their research in the context of different academic careers (research, research-education, and education-focused) to meet and surpass expectations set by the University Academic Excellence Framework.

An In Vitro Investigation of Gas and Dye Leakage at the Implant–Abutment Junction Using Titanium and Cobalt Chrome-Based Abutments Bal, Amylia Kesha; Walton, Terry Richard; Kruse, Hedi Verena; Howes, Dale Geoffrey Abstract The lack of integrity at the implant–abutment junction (IAJ) contributes to problems such as micromovements and microbial colonisation. This study aimed to (1) design a protocol for assessing microleakage at the IAJ using chromophore analysis not previously reported for this specific application, (2) compare gas and dye leakage between titanium (Ti) and cobalt chrome (CoCr) abutments, and (3) assess the effect of gold (Au) gilding on sealing. Forty abutments were divided into five groups: milled Ti (MTi); cast CoCr (CCoCr); milled CoCr (MCoCr); cast CoCr with Au gilding (CCoCrG); and milled CoCr with Au gilding (MCoCrG). Samples were subjected to internal pressure within a gas and dye reservoir. Chromophore analysis via UV-Vis spectrometer was used to calculate crystal violet leakage concentrations. Scanning electron microscopy (SEM) revealed close adaptation in the MTi and MCoCr groups, contrasting with irregularities in the CCoCr groups. Correspondingly, gas leakage and dye leakage were most prevalent in the CCoCr group. Fisher exact test demonstrated a statistically significant difference (p = 0.026) between the MCoCr and CCoCr abutments. While CCoCr exhibited the highest failure rate (62.5%), Au gilding demonstrated a trend toward reduced leakage (25% failure rate), though this did not reach statistical significance (p = 0.315). This chromophore analysis represents a viable and objective assessment of IAJ integrity.

Noel Martin Visiting Chair Seminar-19 March Benzian, Habib Presentation Topic: Realigning Research with Population Impact: Global Strategies- Prof Habib Benzian This presentation will examine how academic institutions can respond to these global recommendations by aligning curricula, research strategy, and funding priorities with the broader NCD agenda. Oral health is not a peripheral specialty issue, but a test case for whether research ecosystems are prepared to translate knowledge into equitable population impact. These recommendations carry significant implications for dental and medical education and research. They challenge universities to rebalance portfolios toward population health, prevention, and system design; to strengthen interdisciplinary collaboration across dentistry, medicine, and public health; and to build capacity in implementation science and health policy analysis. They also raise questions about funding structures that continue to privilege biomedical discovery over delivery and system performance. Oral diseases are among the most prevalent noncommunicable diseases, yet oral health research remains fragmented and often disconnected from mainstream NCD agendas. The WHO Global Oral Health Action Plan sets out clear research and monitoring priorities, calling for stronger surveillance systems, implementation research, health systems evidence, and equity focused approaches that move beyond narrow clinical paradigms.

Dental practitioners are advised to provide evidence-based smoking cessation interventions to their patients, yet dental practitioners frequently fail to deliver brief smoking cessation advice. Objectives To test whether giving dental practitioners a clinical decisions support (CDS) system embedded in their electronic dental record would increase the rate at which patients who smoke 1) report receiving a brief intervention or referral to treatment during a recent dental visit, 2) taking action related to smoking cessation within 7 days of visit, and 3) stop smoking for one day or more or reduce the amount smoked by 50% within 6 months. Methods Two-group, parallel arm, cluster-randomized trial. From March through December 2019, 15 non-academic primary care dental clinics were randomized via covariate adaptive randomization to either a usual care arm or the CDS arm. Adult smokers completed an initial telephone survey within 7 days of their visit and another survey after 6 months. Results Forty-three patients from 5 CDS and 13 patients from 2 usual care clinics completed the 7-day survey. While the proportion of patients who reported receipt of a brief intervention or referral to treatment was significantly greater in the CDS arm than the usual care arm (84.3% versus 58.6%; p = 0.005), the differences in percentage of patients who took any action related to smoking cessation within 7 days (44.4% versus 22.3%; p= 0.077), or stopped smoking for one day or more and/or reduced amount smoked by 50% within 6 months (63.1% versus 46.2%; p = 0.405) were large but not statistically significant. Conclusions Despite interruption by Covid-19, these results demonstrate a promising approach to assist dental practitioners in providing their patients with smoking cessation screening, brief intervention and referral to treatment.

Dental student oral surgery training - Comparing the impact of COVID-19 and cohort sizes Thorpe, Andrew Raymond Darren Scott; Hsu, Joyce; Carter, Eric Francis; Ullah, Mafaz; Cox, Stephen Clive INTRODUCTION: The response to the COVID-19 pandemic potentially reduced the clinical experience and academic education of dental trainees through reduced supervised clinical sessions. Graduating dental students, future employers and regulators may be concerned over the level of clinical experience of graduates trained within the COVID-19 pandemic. The purpose of this study was to try and document the evidence for, and significance of, this impact. MATERIALS AND METHODS: From dental student data in the 2017, 2018, 2019 and 2020 cohorts attending the University of Sydney, Australia, the number of dental extractions and adjunct oral surgery procedures, as well as final end-of-year examination results, was recorded. Results were compared to determine whether differences in experience and final academic achievement existed between these cohorts. RESULTS: The smallest student cohort, 2017, demonstrated greater clinical experience than the 2018, 2019 and 2020 cohorts. The 2020 COVID-19-affected cohort demonstrated no statistically significant reduction in clinical experience in all measured clinical procedures when compared to the 2018 and 2019 cohorts. The decrease in city teaching hospital clinical experience was compensated by an increase in rural placements. The 2020 cohort achieved the lowest academic results, and this was statistically significant. CONCLUSION: The oral surgery clinical experience of the 2020 dental cohort at the University of Sydney was comparable to prior cohorts. Rural clinics were able to compensate for COVID-19 interruptions to clinical training. The number of students in a cohort, if all other variables remain constant, appeared to affect clinical exposure to a greater extent than COVID-19.

The effect of COVID-19 pandemic on final year dental students’ self-confidence level in performing clinical procedures Ilić, Jugoslav; Radović, Katarina; Savić-Stanković, Tatjana; Popovac, Aleksandra; Miletić, Vesna; Lemić, Aleksandra Milić "BACKGROUND: The outbreak of COVID-19 pandemic in 2020 has dramatically changed teaching approach in dental schools due to the switch to distance learning and the lack of practice training in direct contact with patients with possible impact on clinical skills of students. The aim of the study was to assess the level of the 2020 final year dental students' self-confidence in performing different dental procedures through specially designed questionnaire and compare it to self-confidence of the 2019 final year students. MATERIALS AND METHODS: An anonymous questionnaire consisting of 40 questions regarding self-confidence level in performing 40 different dental procedures and based on five points Likert-like scale was distributed during November 2020 to final year dental students whose studies were disrupted by the COVID-19 pandemic lockdown in one semester. The study group comprised their answers. The comparison was done with the control group that consisted of students' answers on the same questionnaire from previous 2019 year conducted as a part of regular internal educational evaluation. RESULTS: Response rate was 74.2% in study group and 89.3% in control group. Mean level of self-confidence reported by 115 students in study group was significantly lower than that reported by 100 students in control group (3.28±1.08 vs. 3.58±0.88, respectively) and the distribution of self-confidence scores were different in observed groups. Graduates from study group felt less confident than those from control in 8 clinical skills. CONCLUSION: Abrupt changes in teaching modalities caused by COVID-19 pandemic had significant impact on final year dental students' self-confidence indicating additional educational needs in postgraduate period."

Errors of interpretation of dental radiographs among dental professionals: A survey Shwethah, Hegde Radiographic interpretations constitute an essential component of information available to dentists when they are formulating a diagnosis. However, interpretation of images is a human endeavour and is subject to the limitations of our ability. Making a correct diagnosis relies on visual detection, pattern recognition, working memory functions and also cognitive reasoning to perceive the meaning of the interpretation. Mistakes may occur in both the visual perception and the cognitive interpretation of images, and this may have serious consequences for the patient. In medical radiology literature, this issue has been recognised for many years, and numerous publications have reported interpretive errors on chest radiographs and mammograms. The rate of interpretation error is in the range of 2-20% and varies depending on the type of radiological investigation. In dentistry, the rate of error of interpretation of dental radiographs is not as well documented. Clinical settings are often hectic with information ambiguous or incomplete, and the dentist is often under pressure to make diagnostic assessments quickly. As radiographic interpretation is reliant on visual perception, errors in interpretation can occur under such constrained conditions. The subjective nature of the interpretation also makes it difficult to establish what is an ‘error’ as opposed to an acceptable variation in opinion. This study explores the occurrence and causes of errors of interpretation of dental radiographs among dental practitioners using an online anonymised questionnaire. With this survey, we aim to evaluate the perceptions of errors, definitions of errors, their contributing factors and strategies to reduce errors. This research will create a benchmark on the incidence and prevalence of errors of interpretation in dentistry and the will be used to improve the diagnostic accuracy of machine learning algorithms.

Variation in Memory T Cells Following Periodontal Treatment Medara, Nidhi T cells are a major cell subset of the adaptive immune system that play a central role in periodontitis. One distinguishing feature of adaptive immunity is immunological memory. Memory refers to the ability of the immune system to respond more rapidly and efficiently to a specific pathogen that has been encountered previously. Memory T cells can be divided into four subsets based on surface expression of CD45RA and CCR7 expression where TN cells are CCR7+CD45RA+, effector memory T cells which re-express CD45RA (TEMRA) are CCR7-CD45RA+, central memory T cells (TCM) are CCR7+CD45RA-, effector memory T cells (TEM) are CCR7-CD45RA-. Periodontal parameters and peripheral blood mononuclear cells were collected from 54 periodontitis patients at baseline, 3-, 6- and 12-months post-therapy and 40 healthy controls. TN, TCM, TEM and TEMRA cells were identified using flow cytometry in CD4+, CD8+, CD4+CD8+ and CD4-CD8- T-cells At baseline, periodontitis subjects had significantly lower TN but higher CD4+ TCM, CD8+ TCM, CD4+CD8+ TEM, and CD4-CD8- TEM cell proportions compared to health. Periodontal therapy decreased TEM and CD4+ and CD8+ TCM cells, but increased TN and CD4+ and CD8+ TEMRA cells. Thus, periodontal management modifies peripheral memory T-cell profile in periodontitis.

Money Where Your Mouth Is: Dentistry and Commercialism Holden, Alexander In this presentation, the audience will be taken on a journey through my current research which explores the nature of the relationship between professional and commercial obligations in dentistry. Using qualitative methods, my work draws out the key themes that demonstrate how the commercial environment of dental practice impacts attitudes towards patients as well as perspectives relating to commercial behaviours such as advertising and competition.
