Fluid flow, in or out of the dentinal tubules is proportional to the tuble diameter by______________?
Correct answer: D. Fourth power of the diameter
- A. Third power of the diameter
- B. Sixth power of the diameter
- C. Square of the diameter
- D. Fourth power of the diameter
Explanation
According to the hydrodynamic principle and Poiseuille's law, fluid flow varies with the fourth power of the tubule radius, and therefore also with the fourth power of its diameter. Even a small increase in tubule diameter greatly increases fluid movement.
