3. air
4. biting*
Anatomy and Etiology
Enamel: •98% inorganic•parallel enamel rods of HA
•crystalline•brittle•not tough
•DEJ: interphase layer• 50:50 collagen/mineral (vol)• ~ 150 microns thick• binds brittle enamel w/ tough•dentin • shock absorber• allows for toughness• prevents crack propagation

SEM etched dentin
SEM DentinDentin:•50% mineral, 30% collagen
•25k/mm @ DEJ•48k/mm @ pulpchamer•2.8 micron diameter @ pulp
•0.8-1micron @ DEJ•peritubular dentin: more highly mineralized
•odontoblast in each tubule

Crack. JOE 1986.Fluid movement through tubulestimulates the odontoblastic processes triggering pain fibers.1. cold - outward
2. heat - compression3. air - stretch, pain ends w/desiccation.
1. identify the correct tooth2. 10-15 gamma3. high speed suction about 3/4 inch away from surface4. apply ozone for about 10 seconds and re-test.5. repeat ozone application until sensitivity gone.6. collect money
Ozone Treatment
Treatment1. turn off pain fibers with ozone2. stop fluid flow with bondable resinsand probably with ‘plugs’ due to remineralization.
Now you know more than most dentists.
Thanks!
