The purpose of this study was to evaluate the ability of three current desensitizing agents Pro-Argin (Colgate Sensitive Pro-relief), NaF with tricalcium phosphate (Clinpro), Nanohydroxyapatite (Aclaim), on dentinal tubule
occlusion using Scanning Electron Microscope.
Nevertheless, sometimes a correctly performed endodontic treatment can fail due to apical radicular dentinal tubule
microorganism invasion capable of adhering and surviving in the root canal by biofilm formation [1,3,6-8].
The evaluations of dentin roughness and depth, diameter, and amount of dentinal tubule
orifice were carried out using AFM (Nanosurf Easy Scan 2, SPM Electronics, Liestal, Switzerland) in contact mode with a silicon nitride (SiN) scanning rate of 49.5 [micro]m/s.
Thus, Kinney et al reported a maximum modulus of elasticity value of 28.3 Gpa, obtained by simulating an isotropic model on dry dentin, by measuring in a direction perpendicular to the dentinal tubule
, while in wet dentin they reported a value of 24.4 Gpa.

Composite adhesive bonding, including self-etch adhesives, relies on the penetration of the primer/adhesive monomers between the exposed collagen fibers and the mechanical interlocking of collagen and polymerized adhesive (39, 40), while the sealers rely on close contact with the dentin surface and dentinal tubule

Owing to their broad antibacterial spectrum and biocompatibility, blank CS-NPs were applied to the treatment of dentinal tubule
infection [7, 8].
(10,38) The smear layer plugs the dentinal tubule
orifices with debris that consists of dentinal shavings, tissue debris, odontoblastic processes, and microbial elements.
penetration of root canal sealers after root canal dressing with calcium hydroxide.
Some methodologies allow direct contact of the irrigant with the microorganism (as in the agar diffusion test) while others, such as in our study, may not necessarily allow a direct contact of the irrigant with the microorganism entombed inside the dentinal tubule
