9.00am The History & Development of the World Federation of Laser Dentistry
Professor Loh Hong Sai, The Chair - World Federation of Laser Dentistry, Asian Pacific Division
This organisation was inaugurated in 1988 (Tokyo, Japan) as the International Society for Laser Dentistry (ISLD). Its objective is to promote international applications and research. Presently, its individual membership comes from more than 55 countries, and has many large national laser organisations in support of its activities. It holds a congress once every 2 years, and the 5 Divisions across the continents would host their regional programs in the year between each congress. Laser certification courses are conducted, together with a MSc program in lasers conducted a group of european member countries.
9.15am Basic Concepts of Lasers in Dentistry Associate Professor Lee Collins
Lasers are a relatively new tool in dentistry. They have the ability to be used to great effect, but also to cause unintended harm to the patient. A good understanding of how the laser functions and how laser radiation interacts with the target tissue is crucial to safe and effective laser use. The talk will cover how the laser functions, its modes of operation, basic tissue interaction mechanisms (thermal and non-thermal), and the biological effects created.
9.45am Update on Laser Safety in Dentistry Associate Professor Lee Collins
As well as providing effective treatment, lasers can also present a hazard – especially optical – to both the staff and the patient as a result of the same interactions used for treatment. However, the level of hazard depends on a number of factors. This talk will cover laser hazards, laser classification, eye protection, other hazards such as plume, and the requirements of the relevant Australian/new Zealand laser safety standards.
Morning Tea
10.30am Laser Tissue Interactions –
Hitting the Target
Professor Laurence Walsh
This lecture summarizes the interactions which occur between the most common laser wavelengths and specific target and tissue components, with a view to optimizing the desirable interactions and reducing bystander effects.
The lecture includes the concepts of coupling energy and of absorption curve shifting, and how these effects can improve absorption.
11.00am Laser operative Parameters – Why More is Less Professor Laurence Walsh
This lecture examines the concepts of ablation thresholds and how the parameters of the laser influence the speed and type of ablation effect achieved, including the collateral heating of the target. This issue is fundamental to gaining the most clinically effective ablation of hard and soft tissues.
Mention will also be made of the differences between panel settings and actual laser emissions from handpieces and fibers.
