In vitro Infection and of Dentinal Tubules
Journal of Dental Research, 1987An in vitro model for dentinal tubule infection of root canals was developed. Cylindrical dentin specimens, 4 mm high with a diameter of 6 mm and a canal 2.3 mm wide, were prepared from freshly extracted bovine incisors. The cementum was removed from all dentin blocks.

Impact of Dentinal Tubule Orientation on Dentin Bond Strength
Current Medical Science, 2018This study aimed to determine the impact of dentinal tubule orientation on dentin bond strength to provide a reference for clinical cavity preparation in resin-bonded restoration. Patients aged 13-16 years were selected, including 18 males and 21 females.

Closing of dentinal tubules by Gluma desensitizer
European Journal of Oral Sciences, 1997Gluma Dentin Bond is an adhesive system, where the primer contains 5% glutaraldehyde and 35% hydroxyethyl methacrylate. Practitioners have reported a strong desensitizing effect of the Gluma system on dentin. This study, thus, sought to evaluate the effect of this system on dentin using various microscopic techniques.

Occluding effect of dentifrices on dentinal tubules
Journal of Dentistry, 2003The 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, 1991Previous 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, 1980This 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.

Root canal dentinal tubule disinfection
Journal of Endodontics, 1990Dentinal 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, 2018The 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, 2011Dentine 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 ...
