Influence of Dentinal Fluid and Stress on Marginal Adaptation of Resin Composites
Journal of Dental Research, 1993 The influence of dentinal fluid and of a number of stress procedures on the quality of the margins of class V restorations located in both enamel and dentin was quantitatively assessed in vitro with the aid of a scanning electron microscope. The materials tested were GLUMA 2000 experimental, Prisma Universal Bond 3, and Syntac, together with the fine ...

Archives of Oral Biology, 2007 To determine the relationship between pain intensity and the rate of fluid flow through dentine in human subjects.The experiments were carried out on 16 premolars in 13 human subjects (aged 15-25 years). Dentine was exposed at the tip of the buccal cusp, etched with acid and covered with saline.

Hydrodynamics of dental dentinal fluid
Stomatology, 2023Background. Dentinal fluid is very close in its physical and mechanical properties and composition to blood plasma, which makes it a potentially aggressive biological environment for modern adhesive systems. An in-depth study of the physiological processes of the functioning of tooth dentin remains relevant in order to solve problems associated with ...

Effect of Dentinal Fluid Composition on Dentin Demineralization in vitro
Journal of Dental Research, 2004Dentin demineralization is reduced by perfusion with water. We hypothesized that a simulated dentinal fluid (SDF) that contains albumin, in addition to electrolytes, would be more effective in reducing dentin demineralization than water alone, and this effect would increase with increasing flow rate of SDF. Perfusion rate in tooth segments that carried

Fluoride uptake in dentin with and without simulating dentinal fluid flow
Clinical Oral Investigations, 1997The aim of the present study was to compare fluoride uptake of dentin with and without simulating dentinal fluid flow. Eighty-five dentinal discs were prepared from retained human molars. Seventeen discs were used to assess baseline fluoride content (controls).

Fluid flow through human dentine
Archives of Oral Biology, 1967Abstract With freshly extracted sound teeth it has been shown that a saturated solution of CaCl2 at 37 °C causes fluid movement through dentine when applied to a small occlusal cavity. Measurement of the rate of flow was made photographically and the maximum value obtained in a group of eight teeth was 4.8 nl/sec.

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. Material and methods: A licensed version of the ANSYS / FLOTRAN computer program was used, which is a software tool for solving various problems of hydrodynamics, including ...

To compare the permeability of the occlusal and the cervical dentinal regions within the same tooth, which represent the bottom of Class I and V cavities, respectively, with two different compositions of perfusion fluid, in vitro.An occlusal and a buccal disc were cut from each extracted third molar at a level close to the pulp chamber.

Dentinal fluid dynamics in human teeth, in vivo
Journal of Endodontics, 1995Cavities were prepared in human premolars scheduled for extraction for orthodontic reasons. The smear layer was removed from the dentin surface by acid etching, and the cavity was sealed using a hollow chamber. The chamber was filled with sterile saline solution and connected via tubing to a hydraulic circuit featuring an adjustable pressure reservoir ...
