All factors govering dentine permeability EXCEPT_______________?
Correct answer: C. Fluid convection
- A. Smear layer
- B. Length of dentinal tubules
- C. Fluid convection
- D. Diffusion coefficient
Explanation
Smear layer, dentinal tubule length and the diffusion coefficient affect dentin permeability. Fluid convection describes a mode of fluid movement through dentin rather than a standard structural or diffusional factor governing its permeability.
