An afternoon of CPD for Recent Graduate Dentists

ADA NSW Centre for Professional Development are hosting an afternoon of CPD for ADA NSW Recent Graduate members featuring presentations by Dr Thai Yeng and Dr Alan Lee.

Case Based Reasoning in Endodontics
What is Case Based Reasoning? As the name implies; it is reasoning based on cases
Presented by Dr Thai Yeng

Case based reasoning (CBR) is the process of solving new problems based on the solutions of similar past problems. Dr Yeng will explain how he uses his experiences to understand and solve new endodontic problems.

Course Topics

 Dr Yeng will use selective cases to explain his reasons for treatment for the following situations:

  • When to choose a smaller or larger apical size preparation in managing teeth with periapical lesions.
  • When to plan for short or long term intra-canal medicament dressing in managing teeth with periapical lesions.
  •  When to consider a non-surgical or surgical retreatment approach for failed root canal treated cases when the patient does not wish to extract the tooth.

Learning Objectives

Case based reasoning (CBR) in endodontics

  • In solving a new endodontic problem, we rely on past episodes of cases encountered by the dentist 
  • We need to remember what endodontic plans succeed and what plans fail based on past patient experiences
  • We need to know how to modify past treatment regime to fit the current new endodontic problem. 
Every endodontic case can be managed using case based reasoning. From the time the dentist spend thinking about the new endodontic problem and start developing a solution strategy for their patient, most dentists will naturally think about other similar problems they have encountered in the past. During this mental review of previous endodontic experiences and associated solutions, the dentist is actually performing CBR. “Reminding” is the process by which case based reasoning takes place.

Successful Management in Ridge Augmentation on Extraction Sockets
How to successfully manage extraction sites for future replacement
Presented by Dr Alan Lee

When tooth/teeth are deemed hopeless and extraction is the final fateful outcome, the extracted socket is usually left to heal by itself. This results in significant resorption of the bundle bone, thus compromising the “foundation” for future implant, bridge and/or denture replacement.  It is thus crucial to plan ahead and prepare the site to prevent drastic loss of bone and further complicated surgeries.  The lecture will emphasize on current literature support and also focus on how to successfully manage the extracted site, ranging from the selection of materials to soft tissue management, based on the experience of the lecturer.

Course Topics
  • Literature review
  • Soft tissue management during ridge preservation procedure at the time of extraction.
  • Selection of materials to ensure long term success and stability of ridge augmentation.
At the end of this lecture, the audience will understand the importance of ridge preservation at the time of extraction.  The audience will also understand more of the type of materials available in the market and be able to select appropriately.  In addition, the audience will also learn about the management of the soft tissues especially in an aesthetically-demanding region.  Dr Lee will also share his experiences in the success and failures of such procedure. 

The bundle bone that remains behind after a tooth is extracted will in no doubt, be completely resorbed during the remodelling process.  The thin buccal plate is usually resorbed, resulting in significant horizontal loss of bone, compromising not only the esthetics, but also the foundation for future tooth replacement.  It is thus crucial that the practitioner informed the patient of the possible sequelae and conveys the message across to the patients.
