  • 1. Chapter 6 Information Technology in Dentistry
  • 2. Education
    • Online education for professionals
    • Computer-generated treatment plans for patients
    • Virtual reality simulations to help train dentists
  • 3. Administrative Applications
    • Electronic appointment book, accounting, and record keeping
    • Electronic dental charting
    • Electronic dental record
  • 4. Demographics and the transformation of Dentistry
    • Early 20 th century, poor care of teeth led to tooth loss by middle age
    • Late 20 th century fluoridated water and better care lead most people to keep their teeth
    • Epidemic of decay among poor children
    • Aging population leads to new specialties in dentistry
  • 5. Computerized Instruments in Dentistry
    • Fiber-optic camera
    • Electronic periodontal probe
    • CAD/CAM to create crowns
    • Digital X-ray
  • 6. Endodontics
    • Diagnoses and treats diseases of the pulp.
    • Use of fiber optics to take pictures of the root canal that dentist and patient can see.
    • Ultrasonic instruments help in root canal therapy.
  • 7. Periodontics
    • Diagnoses and treats diseases of the gums and other structures supporting the teeth.
    • Periodontal disease is more prevalent in older people.
    • Use of electronic probe and electronic charting.
  • 8. Cosmetic Dentistry
    • Attempts to create more attractive smile using
      • Whitening
      • Bonding
      • Dental implants
      • Digital cameras and graphics software to show before and after
  • 9. Diagnosis and Expert Systems
    • Collections of evidence-based articles
    • Databases of articles such as MEDLINE
    • Expert systems
      • EXPERTMD allows the creation of medical and dental expert systems
  • 10. Diagnostic Tools
    • Clinical examination
      • Dentist’s examination using a probe
  • 11. Diagnostic Tools
    • X-rays used for more than 100 years
    • More effective than clinical examination
    • May not detect cavities at an early stage
  • 12. Diagnostic Tools
    • Digital radiography
      • Take less time than traditional X-rays
      • Uses 90% less radiation
      • Image can be immediately seen and shared on a computer monitor
      • Can be scanned into a patient’s digital chart
  • 13. Diagnostic Tools
    • Electrical Conductance
      • Electrical current passed through the tooth and the resistance measured
      • Accurate in the diagnosis of large cavities, not early lesions
  • 14. Emerging Diagnostic Methods
    • Light Illumination
      • A bright light illuminates tooth; decay looks darker
    • Fiber-optic Transillumination
      • Finds early lesions in enamel
  • 15. Emerging Methods
    • DIFOTI®
      • Takes images of teeth illuminated by lasers. Shows direct correlation between loss of flourescence and cavities.
    • Intra-oral Fiber-optic Camera
      • gives dentist and patient a close up view of mouth.
  • 16. Lasers in Dentistry
    • Lasers deliver light energy.
    • Depending on the target, the light travels at different wavelengths.
    • Different lasers have different uses:
      • Drilling and filling cavities
      • Reshaping gums
      • Minimal use in root canal therapy
      • Whitening teeth in cosmetic dentistry
  • 17. Minimally Invasive Dentistry
    • Prevention
      • Antibacterial rinses
      • Fluoride
      • Sealants
      • Healthy diet
      • Sugarless gum
    • Minimal intervention
      • Air abrasion
      • Lasers
  • 18. Computers in Dental Surgery
    • Planning surgery using virtual reality simulations
    • Delivery of anesthesia
    • Creation and planning of dental implants
    • Monitoring of vital signs
  • 19. The Growth of Specialization
    • The percentage of dentists who are specialists is expected to rise from 10% to 30%.
    • The aging population may seek cosmetic dentistry.
    • The possibility of early diagnosis may result in dentists who specialize is diagnostics.
  • 20. Teledentistry
    • Link dentists with dental specialists via telecommunications lines.
    • Images and records can be e-mailed to the specialist giving patients access to expert advice.
