Dentinal tubules driven wetting of dentin: Cassie-Baxter modelling
The European Physical Journal E, 2009We investigate the wetting properties of dentin surfaces submitted to a phosphoric acid etching followed by an air drying procedure, as in clinical situations of adhesive dentistry. The surface topography of the etched surfaces was characterized by AFM, and the wetting properties of water on these rough and heterogeneous surfaces were studied, by ...

Density of dentinal tubules affects the tensile strength of root dentin
Dental Materials, 2004The aim of this study is to count the dentinal tubules in the coronal and middle-apical third of root dentin of teeth extracted due to the progression of periodontal disease, and to compare the Ultimate Tensile Strength (UTS) of the same areas. The research hypothesis was that root dentin areas with different densities of dentinal tubules would also ...

A new method for quantitative analysis of dentinal tubules
Computers in Biology and Medicine, 2007Conventional methods to estimate the number of dentinal tubules cannot be considered reliable and repeatable, because results depends on the operator outlining of the tubules contours. In this study, we propose a totally automated computerized analysis technique to evaluate dentinal tubules and their surface area.

The Lamina Limitans of Human Dentinal Tubules
Journal of Dental Research, 1984Fractured coronal surfaces of both fixed and unfixed human teeth were examined by scanning electron microscopy following HCl demineralization and collagenase digestion. This treatment removed a considerable amount of matrix from the surface of dentin.

Dentine tubule disinfection by different irrigation protocols
Microscopy Research and Technique, 2019AbstractThe purpose of this study was to test the antimicrobial activity and the smear layer removal of different irrigation protocols—sodium hypochlorite (NaOCl), NaOCl followed by ethylenediaminetetraacetic acid (EDTA), and NaOCl combined with etidronic acid (HEBP)—against infected dentine tubules during root canal preparation.

Penetration ability of different irrigants into dentinal tubules
Journal of Endodontics, 1997Dentinal tubules of human root canal walls were infected with a known bacterial isolate. The teeth were divided into two groups and the root canals instrumentated. Different types of canal irrigant were used for each group. In group A, 5% NaOCl was followed by a 10% EDTA rinse and neutralized with a final physiological solution rinse.

One of the factors affecting the success of endodontic treatment is to fill the root canal system hermetically. The aim of this in vitro study was to evaluate the effect of nonthermal plasma (NP) on dentinal tubule penetration of root canal sealers using

Importance of tubule density to the fracture toughness of dentin
Archives of Oral Biology, 2016The fracture toughness of dentin is critical to the prevention of tooth fracture. Within the tooth crown, the mechanical properties of dentin are influenced by spatial variations in the density and diameter of the dentin tubules with distance from the pulp. There are also relevant changes to the microstructure of dentin with age.

Effect of ultrasonic activation on dentinal tubule penetration of calcium silicate‐based cements
Microscopy research and technique (Print), 2019This study investigated the dentinal tubule penetration of mineral trioxide aggregate (MTA), NeoMTA Plus and Biodentine placed by either manual condensation or ultrasonic activation in simulated open apex model.
