Efficacy of different irrigation methods on dentinal tubule penetration of Chlorhexidine, QMix and Irritrol: A confocal laser scanning microscopy study.

Australian Endodontic Journal, 2018
The aim of this in vitro study was to compare the percentage of penetration of three final irrigant into the dentinal tubules after application of several irrigation techniques.

The relationship between dentin microhardness and tubule density

Dental Traumatology, 1985
Abstract The purpose of this study was to determine the possible correlation between dentin microhardness and dentin tubule density in normal human permanent teeth. A new technique was developed which permitted serial determinations of the micro‐hardness and tubule density of the same group of tubules, beginning near to the dentino‐enamel junction and ...

Dentin permeability, dentin sensitivity, and treatment through tubule occlusion

Journal of Endodontics, 1986
The hydrodynamic theory of dentin sensitivity states that movement of tubule contents or tubule fluid, in either direction, causes dentin sensitivity. A corollary of that theory is that anything that can decrease dentinal fluid movement or dentin permeability should decrease dentin sensitivity.

Tubule orientation and the fatigue strength of human dentin

Biomaterials, 2006
In this study the influence of tubule orientation on the strength of human dentin under static and cyclic loads was examined. Rectangular beams were sectioned from the coronal dentin of virgin extracted molars (N=83) and then loaded in quasi-static 4-point flexure or 4-point flexural fatigue to failure.

The density and branching of dentinal tubules in human teeth

Archives of Oral Biology, 1996
Detailed knowledge of dentine structure, and especially that of the dentinal tubules, is essential in order to understand dentine permeability and to interpret data from investigations on dentine adhesive materials. The aim here was to examine the density and branching of dentinal tubules in human teeth by light and scanning electron microscopy ...

Numerical density and distributional pattern of dentin tubules

Acta Odontologica Scandinavica, 1992
By a new method the numerical density and distributional pattern of transversely cut dentin tubules and the diameters of their peritubular dentin walls were measured in sections near the dentin-enamel junction (DEJ), midway to the pulp, and near the pulp wall in human premolars.

Dentin Hypersensitivity. Occlusion of Dentinal Tubules by Brushing With and Without an Abrasive Dentifrice

Journal of Periodontology, 1994
Daily toothbrushing with and without an abrasive dentifrice was performed on the ground surfaces of human cervical dentin attached to resin plates, which had been exposed to the oral cavities of 4 subjects for 8 weeks. Brushing with a dentifrice containing calcium hydrogen phosphate as an abrasive caused most of the dentinal tubules to open.

The fate and the role of bacteria left in root dentinal tubules

International Endodontic Journal, 1995
SummaryIn this article the question of the relevance and consequences of bacteria remaining in the tubules of root dentine after cleaning and shaping of the root canal space is addressed. A second aim is to discuss the necessity of clinical measures taken to eradicate those bacteria that are presumed to survive there.
