  1. Gingivectomy is __________, and provides ___________.
    • excision of the gingiva and the supporting tissue
    • visibility and accessibility to the tooth and / or root surfaces
    • Mostly done in ortho patients.
  2. Gingivectomy - Indication:
    • Elimination of suprabony pockets
    • Elimination of gingival enlargements
  3. Gingivectomy - Contraindications:
    • The need for osseous surgery.
    • Pocket base is apical to the MGJ.
    • NOT for gaining access to the bone.
  4. Modified Widman Flap
    • purpose is to provide access to root surface for debridement
    • Doesn't go beyond MGJ
  5. Gingivectomy - Technique
    • Mark external “pocket markers”
    • Incisions with a Kirkland knife, apical to the marking points
    • move coronally to a point between the base of the pocket & the crest of bone.
    • Remove the excised pocket wall and examine the root surface.
    • Remove any granulation tissue.
    • Suture & / or cover with a periodontal pack.
  6. Gingivoplasty
    • Similar to a gingivectomy, BUT only reshaping the gingiva to create a physiologic gingival contour.
    • This is done in the absence of a pocket.
    • No supporting tissue is removed.
  7. Gingivoplasty - Technique
    • Periodontal knife
    • Scapel
    • Diamond burs
    • To taper or contour the gingival margins
  8. Red complex
    • • T forsynthia - gram negative rods
    • • T denticola - spirochetes
    • P. gingivalis
  9. Periodontal treatment options
    • 1. Surgical intervention - removal of the offending tissue, repair of a defect
    • 2. Chemotherapeutics/immunologic intervention - medically inducing the body to eliminate the diseased cells/genetically altering the host-response to an insult
    • 3. Laser therapy – utilizing specific laser wavelengths for appropriate tissue wound healing modulation. LANAP (laser-assisted new attachment procedure)
    • 4. Scaling and root planing - long junctional epithelium repair. 2 & 3 only work as adjunct of 4.
    • RATE LIMITING STEP - calculus removal / SRP
  10. 4 biggies on the market
    • diode
    • Nd:YAG - for perio
    • erbium
    • CO2
  11. Laser interaction with ANY living tissue is primarily determined by the:
    • Specific Wavelength
    • Tissue Composition
    • Water Content
    • Pigmentation or lack thereof
  12. Common use laser absorption targets..
    • CW Carbon Dioxide (Far-infrared): Water, Collagen, Hydroxyapatite
    • CW Diodes (Near infrared): Hemoglobin & soft tissue melting via heat conduction.
    • ERYAG: Water and Hydroxyapatite
    • CW: Continuous Wave
    • Nd:YAG in pulses: Transparent to water and cell walls (i.e. Endothelial cells, macrophages); Highly absorbed in dark pigment (i.e. black pigmented gram negative anaerobes); Well absorbed in Hemoglobin -> hemostasis; Not well absorbed in CT.
  13. Total
    Triclosan and fluoride toothpaste
  14. Listerine
    Essential oils - menthol, eucalyptol, thymol
  15. Prohealth mouthrinse
    Cetylpyridinium chloride (CPC), quaternary ammonium compound
  16. Prohealth toothpaste
    stannous fluoride (causes staining) + anti-­stain agent
  17. Peridex/Perioguard mouthrinse
    Chlorhexidine mouth rinse
  18. PerioChip
    Chlorhexidine chip
  19. Arestin microspheres
    • Tiny round particles with minocycline
    • Atridox - doxycycline gel, replaced by arestin
    • Actisite - fiber w/ tetracycline
  20. Periostat
    Low dose doxycycline tablets
  21. If there is crestal Lamina Dura present,
    NO active disease.
  22. In the absence/diffuse of the crestal Lamina Dura,
    there could be either Active or no Active disease.
