Dr Vianna is a Senior Clinical Lecturer/Honorary Consultant in Endodontology and joined Cardiff Dental School in March 2016. She graduated from the Dental School of Ribeirão Preto, University of São Paulo (USP), Brazil in 1993. After attending a 2 year FT residency course, she became a specialist in Endodontology at the University of São Paulo in 1996. Subsequently, she worked as an Endodontist in the Army General Hospital of Sao Paulo, and as a general dentist in the Dental Public Health Service. During this period, she became a specialist in Public Health in 1998. After this, she embarked on academic development and attended a Full-time MSc course in Clinical Dentistry (Endodontics) at the Piracicaba Dental School, University of Campinas, Brazil, gaining her degree in 2002. She followed this with study and research for a PhD degree in the same subject and university. She developed part of her PhD research in Germany (University Hospital RWTH - Aachen) in the field of Molecular biology in the Oral Microbiology and Immunology Department. In 2006, she gained her degree and an honors prize from the Minister of Education of Brazil (CAPES) for one of the best PhD thesis in the field of Dentistry. She worked as an Assistant Professor at the Piracicaba Dental School, where she also participated as docent in the post-graduate programmes of the Clinical Dentistry (MSc, PhD, and continuing education courses) and, since 2008 as Programme Coordinator for the MSc and MClinDent programmes in Endodontology at the UCL- Eastman Dental Institute from 2008 to 2016. She was Deputy Director of Education for the Eastman Dental Institute from 2013 to 2015.
She teaches and supervises at PhD, MSc and BDS levels. She teaches extensively on the MClinDent in Endodontology course for which she is module lead for multiple modules. She is heavily involved in all aspects of teaching on theses Masters level courses including course design, planning and delivery of didactic lectures, small group tutorials, clinical case discussions, clinical laboratory demonstrations and supervision, seminars and group discussions. As well as the lecture and clinical based teaching she has considerable microbiology experience which has allowed her to supervise various microbiology based research projects for students undertaking different levels degree including PhD, MSc, MClinDent, and undergraduate.
Her teaching portfolio also includes didactic and clinical and laboratorial teaching for undergraduates and postgraduate levels; research supervision of Masters and PhD projects in clinical translational research of oral microbiology.
Dr Vianna research experience and interest lies with the infected root canal environment, periodontium and oral microbiology. The research topics include testing endodontic materials, endodontic irrigating solutions and techniques using a variety of experimental cultured based approaches. Multidisciplinary collaborations are always welcomed, for example Dr Vianna has developed with Biomaterials and Tissue Engineering tests to evaluate the antimicrobial potential of new materials for dentine and bone repair and regeneration. One of the major areas of her research activities is based on molecular biology to answer microbiological questions such as the composition of the microbiome within endodontic infections and she was the first person to demonstrate that members of the Archaea kingdom of life could be repeatedly found in root canals with endodontic infections (Vianna et al 2006) which has formed the basis of a completely new area of clinical investigation in oral biology. Her most recent research activities involves to investigate the microbiology of endodontic infections in order to develop translational evidence based knowledge to the endodontic clinic with the ultimate aim of improvement in clinical outcomes following treatment. These include in-depth studies to determine the entire microbiome associated with endodontic disease using a next generation sequencing approach and an analysis of levels of antimicrobial resistance within members of this bacterial community.
Her research activities have been extensively publicised in conferences and dental schools meetings (>80 poster and oral presentations) and she has >30 publications in peer-reviewed journals. With an H-index of 19 (Scopus).
