Diagnosis and emergency care of dental trauma
Main Scientific Program
Thursday 2nd May
8:05 AM - 9:00 AM

For most dental injuries the time from the injury to treatment can differentiate between saving a tooth or losing it to complications.  
Therefore it is paramount for all dentists to have some understating on diagnosis and emergency treatment of the most common dental injuries. The first part of the lecture will give an overview of diagnostic procedures necessary in case of oral and dental trauma, including radiographic, facio-skeletal and oral evaluations. The second part will focus on most common treatment modalities for fractured crowns and roots, luxation and avulsion, with emphasis on the best initial or emergency response. 

Learning Outcomes:

  • To educate the clinician necessary diagnostic protocol after most common dental injuries
  • To educate the clinician about urgency of treatment for most common dental injuries
  • To educate the clinician about most common treatment options for dental injuries

Late Complications and Edodontic Considerations after Dental Trauma
Main Scientific Program
Friday 3rd May
11:20 AM - 12:05 PM

Almost all dental luxation injuries and every avulsion will cause damages to the periodontal ligament, to which the inevitable sequel is varying degree of root resorption.  Recently new treatment approaches have been suggested in the attempt to reduce or even prevent some root resorption types.  In this lecture will give an overview of most common root resorption types and some detailed discussion will be given on which types of root resorptions is possible to prevent and/or treat.  This discussion will include evaluation of risk/benefit of using calcium hydroxide in modern trauma dentistry.

Learning Outcomes:

  • To educate the clinician about different types of root resorptions.
  • To educate the clinician about treatment options for most common types of root resorptions.
  • To educate the clinician about latest thoughts about calcium hydroxide use in dental trauma.

Alveolar preservation in children after severe dental trauma
Main Scientific Program
Friday 3rd May
4:00 PM - 4:45 PM

The most challenging sequel to dental trauma is loss of a permanent anterior tooth in a growing child. Fortunately, it is possible in some of those cases to close the gap by orthodontically.  However, in number of patients this is not possible and then it becomes a priority to preserve the alveolar bone until the child is fully-grown and implant can be placed.  This is because if the root is extracted in a young child there is a high risk of arrested vertical growth of the alveolus, making an implant placement at later time difficult.  Recently it has been suggested that in some cases it is better to leave the root in place rather than extract it to preserve the bone and thereby preventing those complications. 

Learning Outcomes:

  • To educate the clinician about complications associated with premature loss of tooth in a growing child.
  • To educate the clinician about possible treatment options teeth with guarded prognosis.
  • To educate the clinician about outcome assessments of decoration and/or root submersion

Is it really toothache? Odontogenic vs Non-Odontogenic pain
Main Scientific Program
Saturday 4th May
2:35 PM - 3:20 PM

A correct endodontic diagnosis is fundamental prior to any endodontic therapy. Over the years our understanding on benefits and shortcomings of the traditional “vitality” tensing methods has greatly improved. However when a patent presents to the dental clinic with chief complaint of facial pain that is not associated with a specific tooth our many traditional test will often fail us. This lecture will focus on facial pain that mimics toothache such that the patient beliefs the pain is coming from a tooth but actually it is caused by non-odontogenic diseases. The lecture will systemically review, with the aid of actual clinical cases, most common diseases that can cause this confusion and differential diagnostic techniques will be discussed for each.

Learning Outcomes:

  • To present an overview of most common sources of acute oral facial pain.
  • To present diagnostic approached and techniques in endodontics.
  • To present most common reasons for acute facial pain that can mimic pain of dental origin.
