Effects of the degree of tubule occlusion on the permeability of human dentine in vitro
Archives of Oral Biology, 1978Abstract The effects of changes in the nature of dentine surfaces on the permeability coefficients of 3H2O and 131I-albumin were determined in vitro. From these data, diffusional surface areas were calculated. The dentine surface was altered from a highly-polished surface to a bur-roughened surface, to an acid-etched surface and to an oxalate-treated

Occlusion of dentinal tubules under superficial attrited dentine.
Swedish dental journal, 1981A scanning electron microscope (S.E.M.) was used to examine dentinal tubules transversely fractured approximately 1.5 mms below a superficial dentinal attritional surface. The material not only included vital teeth but also young, intact premolars implanted into removable dentures.

Occlusion of dentin tubules by desensitizing agents.
American journal of dentistry, 2005To evaluate the occluding effect of five desensitizing agents on human dentin tubules.30 buccal and lingual surfaces were prepared from 15 extracted intact third molars. Each surface was polished with aluminum oxide abrasive papers to remove enamel and to expose the underlying dentin in cervical area.

Effects of Dentifrices on Subsurface Dentin Tubule Occlusion: An In Situ Study
International Journal of Prosthodontics, 2015To evaluate, in situ, the penetration of deposits formed within the subsurface of dentin samples treated with desensitizing dentifrices designed to occlude dentin tubules compared to two controls.Twenty-eight healthy participants wore left and right intraoral appliances, each retaining four human dentin samples, for two periods of 4 days.

Clinical Oral Investigations, 2019
To investigate the effect of toothpastes on dentine surface loss and tubule occlusion, and the association of toothpaste-related factors to each of the outcomes.One hundred and sixty human dentine specimens were randomly distributed into 10 groups, according to different toothpastes.

Laser-assisted cerium oxide mineralization for dentinal tubule occlusion
Dental MaterialsThis study aimed to develop a synergistic strategy integrating in-situ deposition of cerium hydroxide with laser irradiation to achieve efficient and acid-resistant occlusion of dentinal tubules (DTs) for dentin hypersensitivity (DH) management, while conferring antibacterial activity to the dentin surface.An "alternate soaking" approach, involving ...

To evaluate the occluding ability of ammonium hexafluorosilicate (SiF).Dentin disks prepared from human extracted teeth were grouped as follows to prepare different situations of dentin hypersensitivity: (1) those sonicated for 20 minutes; (2) those treated with 0.5 mol/L EDTA for 2 minutes; (3) those treated with 6% citric acid for 2 minutes; (4 ...

The effect of desensitizing dentifrices on dentin wear and tubule occlusion.
American journal of dentistry, 2016To evaluate the effect of desensitizing dentifrices on dentin erosive wear, using a 5-day erosion-abrasion-remineralization cycling model. The effect of the dentifrices on dentin's tubule occlusion was also investigated.30 samples of root dentin were randomly divided into three groups (n = 10): (1) Colgate Total 12 Clean Mint (control, 1,450 ppm F); (2)

Protection, remineralisation and tubule occlusion of dentine by desensitising toothpastes [PDF]
, 2020 Enamel is one of the strongest and highly mineralised tissues in the human body and it protects the underlying dentine. The high mineral content of the enamel makes it susceptible to erosive wear via dissolution of the ions in low pH. Loss of the minerals also softens the enamel, making it vulnerable to further damage by mechanical and chemical ...
