Comparing dentinal tubule penetration of conventional and 'HiFlow' bioceramic sealers with resin-based sealer: An in vitro study.

Australian Endodontic Journal, 2020
This study compared the depth and percentage of dentinal tubule penetration for single-cone (SC) and warm vertical (WV) obturation techniques with two different bioceramic sealers (BC Sealer [BCS], BC Sealer HiFlow [BCSHF]) and an epoxy resin-based ...

Occluding effect of dentifrices on dentinal tubules

Journal of Dentistry, 2003
The objective of this study was to evaluate the tubule occluding ability of three commercial available dentifrices (Sensodyne, Emoform and Sorriso) by Scanning Electron Microscopy.Fifty cervical areas from buccal and lingual surfaces of sound third human molars were used.

Dentinal Tubule Occlusion and Root Hypersensitivity

Journal of Periodontology, 1991
Previous studies have established that root sensitivity is due in part to open dentinal tubules at the root surface. The purpose of this study was to longitudinally evaluate the occlusion of dentinal tubules by various clinical procedures including scaling and root planing and the application of potassium Oxalate.

In vivo resin impregnation of dentinal tubules

The Journal of Prosthetic Dentistry, 1980
This study investigated the in vivo resin impregnation of dentinal tubules on exposed dentin surfaces with transversely cut tubules and examined the effect of different pretreatment on impregnation of the dentin. The results have lead to the following conclusions: 1.

[The results of computer simulation of the dentinal fluid hydrodynamics in the open crown dentinal tubule].

Stomatologiia, 2020
OBJECTIVE To study the hydrodynamics of the dentinal fluid along the dentinal tubule in the event of its opening as a result of mechanical and acid treatment of the dental crown dentin.

Root canal dentinal tubule disinfection

Journal of Endodontics, 1990
Dentinal tubules of the root canal walls of human teeth were infected in vitro with a known bacterial isolate. The roots were exposed to either calcium hydroxide or iodine potassium-iodide for various periods of time and the viability of microorganisms was determined by incubation of entire root samples in a culture medium.

An In Vivo Study of Dentin Sensitivity: The Relation of Dentin Sensitivity and the Patency of Dentin Tubules [PDF]

Journal of Periodontology, 1991
Dentin hypersensitivity can be a major problem for periodontal patients. The relationship between dentin hypersensitivity and the patency of dentin tubules in vivo has been established. Thirteen adult patients with teeth scheduled for extraction were selected and a stent fabricated to confirm location of the root surface being examined.

Effect of chitosan on sealer penetration into the dentinal tubules

Nigerian Journal of Clinical Practice, 2018
The objective of this study is to compare the effectiveness of final irrigation with chitosan, ethylenediaminetetraacetic acid (EDTA), and citric acid (CA) on a resin-based sealer (AH plus sealer [Dentsply DeTrey, Konstanz, Germany]) penetration into dentinal tubules using confocal laser scanning microscopy.Seventy recently extracted human mandibular ...

Efficacy of desensitizing dentifrices to occlude dentinal tubules

European Journal of Oral Sciences, 2011
Dentine hypersensitivity occurs when patent dentinal tubules are subjected to external stimuli, with pain being reduced by products that occlude tubules. This study compared the efficacy of a recently developed arginine-containing dentifrice, two established strontium-based products, and a fluoride control to occlude tubules when subjected to acid ...

A theoretical model of dentinogenesis: Dentin and dentinal tubule formation

Computer Methods and Programs in Biomedicine, 2013
Dentinogenesis, odontoblast dentin formation, includes dentinal growth, mineralization and dentinal tubule formation. Odontoblasts synthesize collagen resulting in collagen apposition contributing to dentinogenesis. Furthermore, within the tubule, they express non-collagenous proteins, such as dentin phosphoprotein (DPP), associated with hydroxyapatite
