  • 1. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts
    By: Bruce D. Patterson, Ellis J. Nieburger, and Samuel M. Kasiki
    Summarizes by: Goua Vang
  • 2. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts
    Study
    Why?
  • 3. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts
    Specific question?
    Man-eater are frequently through to be old or infirm, apparently incapable of normal predatory behavior
    Famous tiger hunter Jim Corbett repeatedly found that notorious man-eating tigers had broken teeth or claws, crippling arthritis, prior gunshot wounds
    Is this true?
  • 4. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts
    Specific approaches
    Examined the holding of skulls of Lions with permanent dentitions in 3 international study collections
    These represented free-living lions without recorded misdemeanors against human
  • 5. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts
    Specific approaches
    Compare free lions skulls with lions skulls in Tsavo East National Park, Kenya that were killed outside the park by rangers (control man-eater)
    Distinguished teeth broken before and after death by assessing tooth wear
    Age by tooth wear
    Record tooth: fractures that became subsequently worn, breakage and wears on all 30 teeth
    153 specimens
  • 6. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts
    Results
    63 of 153 lions had damaged dentitions (form of worn and broken teeth which exposes the pulp cavity of the tooth to infection and decay)
    How much influence does it play in killing large prey?
  • 7. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts
    Incisors and canines with pulp exposures
    Broken incisors and right canine with pulp exposures
    Broken incisor and canine with pulp exposure
    Broken left 4 premolar with alveolar erosion
    Broken left 2 premolar with alveolar erosion
    Broken left 4 premolar with alveolar erosion
    Right 4 premolar with pulp exposures from wear
    Left 4 premolar with pulp exposures and alveolar erosion

  • 10. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts
    Conclusion
    40% of the lions examined had broken teeth
    The problem lion sample TENP, Kenya should have the most
    Any phenomenon as complex as man eater seldom has a single cause
  • 11. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts
    Questions remained unanswered
    Habitat
    Low availability of natural preys
    Population
