Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts

  1. 1. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts<br />By: Bruce D. Patterson, Ellis J. Nieburger, and Samuel M. Kasiki<br />Summarizes by: Goua Vang <br />
  2. 2. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts<br /> Study <br />Why?<br />
  3. 3. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts<br />Specific question?<br />Man-eater are frequently through to be old or infirm, apparently incapable of normal predatory behavior<br />Famous tiger hunter Jim Corbett repeatedly found that notorious man-eating tigers had broken teeth or claws, crippling arthritis, prior gunshot wounds <br />Is this true? <br />
  4. 4. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts<br />Specific approaches <br />Examined the holding of skulls of Lions with permanent dentitions in 3 international study collections <br />These represented free-living lions without recorded misdemeanors against human <br />
  5. 5. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts<br />Specific approaches <br />Compare free lions skulls with lions skulls in Tsavo East National Park, Kenya that were killed outside the park by rangers (control man-eater) <br />Distinguished teeth broken before and after death by assessing tooth wear<br />Age by tooth wear <br />Record tooth: fractures that became subsequently worn, breakage and wears on all 30 teeth <br />153 specimens <br />
  6. 6. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts<br />Results<br />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) <br />How much influence does it play in killing large prey?<br />
  7. 7. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts<br />Incisors and canines with pulp exposures<br />Broken incisors and right canine with pulp exposures<br />Broken incisor and canine with pulp exposure<br />Broken left 4 premolar with alveolar erosion<br />Broken left 2 premolar with alveolar erosion <br />Broken left 4 premolar with alveolar erosion <br />Right 4 premolar with pulp exposures from wear<br />Left 4 premolar with pulp exposures and alveolar erosion <br />
  8. 8. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts<br />
  9. 9. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts<br />
  10. 10. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts<br />Conclusion <br />40% of the lions examined had broken teeth <br />The problem lion sample TENP, Kenya should have the most<br />Any phenomenon as complex as man eater seldom has a single cause<br />
  11. 11. Tooth Breakage And Dental Disease As Causes Of Carnivore-Human Conflicts<br />Questions remained unanswered<br />Habitat <br />Low availability of natural preys <br />Population <br />
