| Dr Rob Hirsch | Azithromycin in periodontal therapy: more than an antibiotic | |
 |
Azithromycin is a macrolide antibiotic related to erythromycin, but with a significantly enhanced spectrum of activities and low incidence of side effects. Although only available in Australia since 2004, azithromycin has been used in the treatment of a wide variety of infections in the USA and Europe since about 1991. Later in the 1990’s, it became apparent that azithromycin also has immune-modulating properties which have been applied in the management of cystic fibrosis and asthma. The activity of azithromycin against periodontopathogens; its anti-inflammatory properties and potential capability of changing macrophage phenotype give it biologic plausibility as a unique host-modulator in the management of inflammatory periodontal diseases. Through a series of case reports of patients treated over the last 2 years with azithromycin (as the only treatment or as an adjunct to closed subgingival debridement), this presentation highlights the anti-inflammatory, healing and bone regenerative potential of azithromycin in advanced periodontitis. In addition, cases of the efficacy of azithromycin in treating drug-induced gingival overgrowth will be presented. This property of azithromycin has been studied outside of the periodontal literature from 1995-2007 but it is perplexing that it has not translated to periodontal theory or practice. A protocol for the use of azithromycin in periodontal therapy based on clinical experiences over the last 2 years will be presented. This presentation is intended to initiate discussion amongst ANZAP members about the role of azithromycin in periodontal therapy. Biography: Dr Robert Hirsch BDS, MDS, PhD Graduated MDS (Perio) from the University of Adelaide in 1976. After completing a PhD in 1983, he has been involved in the organisation and delivery of the undergraduate and graduate periodontal teaching programs at the School of Dentistry, University of Adelaide. He also maintains a specialist practice limited to periodontics. |

| Dr Neil MacGregor | The genetics of alcohol related mouth cancers: Possible susceptibility issues with alcohol containing mouth rinses | |
 |
A review of the evidence associating the usage of mouthwashes with oropharyngeal/esopharygeal neoplasm (OEN) will be presented. There is significant evidence for the cumulative effects of smoking and alcohol use upon OEN development. Whilst low levels of alcohol intake appear to be protective of development of OEN in Caucasians, the cumulative effects of smoking and alcohol (from multiple sources, including mouthwashes) are associated with increased risk of OEN. The relationships between smoking, alcohol metabolising enzymes, Alcohol and Aldehyde Dehydrogenase will be discussed. Low alcohol mouthwashes in Caucasian subjects who do not drink or smoke may be protective of OEN but the usage of these alcohol containing mouthwashes may be detrimental in up to 35% of East Asian subjects.

| Dr John Goodman | After forty years in perio is there anything left worth saying? | |
 |
Our profession (specialty) is predominantly a procedural one. A strong case can be made that many of us are attracted to dentistry (Periodontics) because we have a personal bias in this direction – the procedural one. Conversely, in our practises and training programmes, consultative skills tend to be undeveloped and atrophied. This is in spite of the knowledge that patients often take our technical skills for granted and judge us more on our consultative skills.
An attempt is made to address this problem. Don’t forget teeth (gums) have people! Biography: Dr John Goodman BDS, MDSc John Goodman graduated from Sydney University and was employed in private practice in the UK and Sydney from 1952 to 1958, then became a principle in private practice in Sydney for eight years. After graduating MDSc, at Sydney University in 1969, he was a principle in a private specialist periodontal practice in Sydney, until 2009 when he retired. He has served as president NSW branch Australian Society of Periodontology; president of ANZAP; and senior visiting dental officer Periodontal Department of Westmead Hospital. He is currently a supervisor in graduate training at United Dental Hospital Sydney. |

| Associate Professor Dr Axel Spahr | Periodonal regeneration: current concepts - future prospects |
|
 |
Considerable advances have been made in recent years in regenerating lost tooth supporting tissues due to the development of new methods and materials for periodontal regeneration. Therapy of marginal periodontitis is aimed at complete regeneration of lost periodontal tissues (restitutio ad integrum) rather than merely preventing further attachment loss. So far, attempts of periodontal regeneration have been made by using various non-resorbable and resorbable membranes according to the principles of guided tissue regeneration (GTR) as well as different types of bone grafts or bone substitutes. However, all these strategies are based on a more or less mechanistic philosophy. In 1995, the introduction of a rather different and innovative approach took place, when European authorities and the FDA approved an enamel matrix protein preparation (Emdogain) as biological based device for periodontal regeneration. Other attempts to regenerate the periodontal tissues have been made using different growth factors. The objective of this presentation is to outline and evaluate past and current concepts of periodontal regeneration and to describe possible developments in the future. Biography: A/Prof. Axel Spahr Dr. med. dent. habil. Axel Spahr is Head of Periodontics at the Sydeny Dental Hospital and Clinical Associate Professor at the University of Sydney. He is the former Head of Periodontics at the University of Ulm in Germany and has worked at various international universities and research facilities. He has a further training in microbiology and molecular biology and extensive experience in basic science research, animal research and clinical research. A/Prof. Spahr’s research interest includes periodontal regeneration, enamel matrix proteins (Emdogain), bone regeneration, periodontitis and systemic diseases as well as antimicrobial therapy. He has lead large externally funded research projects and is collaborating with leading international research groups and companies in the field of periodontology, implantology and bone regeneration. He is author of numerous publications in international peer-reviewed dental and medical journals and has presented his work on professional conferences worldwide. |

| Dr Warwick Duncan | Mucocutaneous disorders affecting the gingiva. How should the periodontist manage these? | |
 |
Mucocutaneous disorders are conditions with an autoimmune component that may present as erythematous, erosive, vesiculobullous or desquamative lesions of the gingiva. These patients are frequently referred to the periodontist for treatment of the primary condition, or for management of secondary periodontal disease resulting from the patient's inability to perform adequate oral hygiene, or for surgical management of recession. Current thinking in the diagnosis and management of these patients will be reviewed. Biography: Warwick J Duncan ED, BDS MDS PhD FRACDSPerio Warwick Duncan is a senior lecturer in Periodontology and Associate Dean at the Otago University Dental School, where he coordinates the Doctorate in Clinical Dentistry in Periodontology. He graduated from Otago University BDS with credit (1985), MDS in Periodontology with Distinction (1992) and PhD in Implantology (2006) and completed the Fellowship in the Royal Australasian College of Dental Surgeons (Periodontics) in 2001. He has also been awarded the Efficiency Decoration (ED) for 30 years reserve military service. He has been active in dental implant research in humans and animal models for 17 years, and is also involved in studies investigating the genetic basis for periodontal diseases and their relationship to other non-dental conditions. Current research collaborations include Zurich University, Switzerland (implants, bone replacement grafting and stem cells), Chonbuk University, Korea (oxidised implants), Southern Implants, South Africa (titanium and ceramic implants) and Neoss Australia (modified implant surfaces). He is also supervising implant research projects by three DClinDent students and five PhD students. |

| Dr Patrick Tseng | Implant design and tissue stability | |
 |
In the last few years, a number of new implant design features have emerged. Apart from promoting bioactive surfaces or surfaces modified with nano-technology, all major implants companies now market implants with macro- design features which appear very different from the traditional Branemark external hex implant. Features such as platform shifting, internal connection, micro-threads, textured surface replacing the smooth collar, laser etching have all been reported to minimise bone loss around implants, and therefore promoting tissue stability in the long term. The rationale and evidence for such macro-design features in the literature will be reviewed. A case report series on an implant system with some of these features used in a private practice will be presented, and the validity of such claims will be discussed.

| Dr Greg Peake | Sinus floor augmentation using a transcrestal approach: where do I draw the line? | |
 |
The posterior maxilla has traditionally been a challenging area for dental implant placement. Bone volume and bone quality had impacted negatively on implant success rates. The use of a transcrestal approach to sinus floor augmentation has been widely used and reports indicate a high degree of predictability, when this technique is performed. This presentation will attempt to establish the limitations and pitfalls of this procedure. |
|
| Dr Louise Brown | Bishopsphonate-induced ONJ and implants: a real or imagined problem? | |
 |
The emeregence of osteonecrosis of the jaw (ONJ) as a complication of the use of bisphosphonate medications attracted its fair share of mainstream media coverage. As well, the medical and dental professions have endeavoured to warn the profession about the needs to exercise extreme caution for this group of patients. As dental implant treatment is often an elective treatment, rather than a necessary treatment, there is confusion over whether implant treatment is contra-indicated in patients taking bisphosphonates. This presentation will examine the effects of the media in the dispersion of knowledge and the accuracy of such reports, and how this may affect the basis on which a patient makes decisions. It will also examine the guidelines available to guide us, as clinicians, in directing decisions about treatment planning for this group of patients. Biography: Dr Louise Brown BDSc, MDSc, MPH, PhD, MRACDS (Perio) Dr Brown is a specialist periodontist, working full time in her private periodontal practice in Kew. She completed her undergraduate dental and postgraduate periodontal education at Melbourne University. She was awarded a PhD from the University of Adelaide and also spent two years at the University of North Carolina, working in the field of periodontal epidemiology and completing a further degree. Dr Brown has been awarded numerous Fellowships and research grants, leading to publications in international refereed journals. She is actively involved in the periodontal profession, currently serving as Vice-President of ANZAP. |

| Dr Michael Danesh-Meyer | Ridge preservation post-extraction: often recommended but seldom practised | |
 |
This presentation will examine the clinical indications for site preservation; review the current evidence on the use of socket augmentation prior to implant placement. Clinical techniques and materials for managing both hard and soft tissues will be discussed. Biography: Dr Michael Danesh-Meyer BDS MDS (Periodontist) Dr Danesh-Meyer gained his BDS and MDS (with Distinction) from University of Otago. He subsequently taught at the University and was in full-time private practice limited to dental implants and periodontics in New Zealand prior to his academic appointment in the USA. From 1998-2000 he was Clinical Assistant Professor in Periodontology and Associate Scientist in the Laboratory for Applied Periodontal and Craniofacial Regeneration at Temple University, School of Dentistry in Philadelphia. He has been involved in preclinical and clinical research involving GTR/GBR & dental implants since 1991, has authored numerous articles and lectures both nationally and internationally on topics related to tissue regeneration and dental implant therapy. While in the USA he was involved in research using recombinant bone morphogenic proteins (rhBMP-2) for periodontal and alveolar regeneration. Dr Danesh-Meyer retuned to New Zealand in 2000 and established the Institute of Dental Implants & Periodontics and the Auckland Clinical Training Centre in Newmarket, Auckland.

| Dr David Grossberg | Adjacent implants in the anterior maxilla: is papilla preservation really possible? | |
 |
Despite our advances in most aspects of dental implants, the maintenance and reconstruction of the inter implant papilla remains a difficult task. Several procedures and have been described and changes in implant technology have attempted to resolve this problem. This interesting topic will be discussed with relevance to the patients we treat on a regular basis. Biography: Dr David Grossberg Dr Grossberg is Specialist Periodontist in Sydney. He obtained his post graduate training in Periodontics at the University of Pennsylvania and is a Diplomat of the American Board of Periodontology. He is a Specialist Clinical Associate in Periodontics at the University of Sydney, Fellow of the International College of Dentists and Past President of the Australian and New Zealand Academy of Periodontists.
