Diastema treatment splits opinions amongst equine practitioners with some advocating flushing & packing of the interdental space and periodontal pockets and others in favour of diastema widening to prevent food from getting trapped. Then, there is of course the view that tooth extraction should be used in certain cases... The distinguished panel of international equine dentistry specialists will debate available treatment options and share their views, opinions and tips & tricks that they found helpful.


  • What is the ‘gold standard’ in working up horses with diastemata?  What diagnostic limitations need to be considered?
  • What depths of periodontal pockets associated with diastemata make burring or widening a futile endeavor? What parameters should be considered here?
  • Should we packing diastemata when we can’t be sure that they are clean?


  • Does burr positioning at a right angle to the teeth during burring, as shown in some papers, increase the risk of pulp exposure?
  • How essential is water cooling when burring diastemata? If one doesn’t have water cooling whilst burring, at what time intervals should one stop and flush to cool the teeth.
  • Is partial diastema widening (occlusal relief cutting) an under-utilized treatment for diastemata?
  • Is tooth extraction an underused method of diastema treatment?


  • What medium-to-long-term bone regeneration/remodeling capacity can one expect in young horses with periodontitis?
  • How do the different therapeutic techniques compare in respect to functionality, long-term resolution and recurrence?

"I find the panel discussions very helpful...areas of consensus and dissention are illuminated and the conversations make it more understandable as applied to individual cases or situations".
