Mechanism
Hydrodynamic theory —M.Brä nnströ m in 1967
The fluids within the tubule are disturbed either by temperature changes or physical osmotic changes. These fluid changes stimulate a baroreceptor which leads to neural discharge (depolarization).
Baroreceptor: a never receptor sensitive to pressure
Treatment
A challenge for both the patiห้องสมุดไป่ตู้nts and dentists.
It’s difficult measuring/comparing different patient’s pain. It’s difficult for patients to change the habits.
Reasons for Continued Dentinal Tubular Exposure
1. 2. 3. 4. 5. Poor plaque control, acidic bacterial byproducts Excess oral acids, sodas, fruit juice Cervical decay Toothbrush abrasion Tartar control toothpaste
1. 2. 3. 4. 5. 6. 7. 8. Inadequate attached gingiva Prominent roots Tooth brush abrasion Pocket reduction periodontal surgery Oral habits resulting in gingival laceration Excessive tooth cleaning Excessive flossing others
