Self-contamination of deep dentin by dentin fluid.
American journal of dentistry, 2002To compare, with the use of a resin replica technique, surface features of deep, acid-conditioned dentin from vital human molars that were anesthetized with an anesthetic: Group 1: without a vasoconstrictor (Mepivacaine 3%), and Group 2: containing a vasoconstrictor (Lidocaine 2% with 1:80,000 epinephrine).10 Class I cavities with dentin caries were ...

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.

Dentine phosphoproteins in gingival crevicular fluid during root resorption
The European Journal of Orthodontics, 2004External apical root resorption is a common, yet unexplained, phenomenon associated with orthodontic treatment. Available methods of clinical evaluation are radiographic. Biochemical assays offer the advantage of being non-invasive, as well as being diagnostic and potentially prognostic.

Effect of Er,Cr:YSGG laser on human dentin fluid flow
Lasers in Medical Science, 2012The aim of the current investigation was to assess the rate and magnitude of dentin fluid flow of dentinal surfaces irradiated with Er,Cr:YSGG laser. Twenty extracted third molars were sectioned, mounted, and irradiated with Er,Cr:YSGG laser at 3.5 and 4.5 W power settings.

Relationship of Fluid Transport Through the Dentin to the Incidence of Dental Caries
Journal of Dental Research, 1971The rate of fluid movement in the teeth of 28-day-old rats is inversely related to the incidence of dental caries after 13 weeks of the same diets. The early hypomineralization found in the dentin at 28 days is a result of altered metabolism imposed by a reduced rate of fluid transport in the rats fed a cariogenic diet.

Interfacial characteristics of Biodentine and MTA with dentine in simulated body fluid
Journal of Dentistry, 2015Newer tricalcium silicate cements (TSC) may offer biocompatibility with improved working properties. This study aimed to evaluate: (1) the occurrence of mineral deposition at the interface between dentine and two TSC (ProRoot(®) MTA and Biodentine(®)) in simulated body fluid, and (2) to investigate the nature of interfacial layer.Six root dentine ...

A photochemical method for in vitro evaluation of fluid flow in human dentine
Archives of Oral Biology, 2015To evaluate the flow dynamics of dentine fluid using a chemiluminescence method in vitro.Horizontally sliced coronal dentine specimens with thicknesses of 1.4, 1.6, 1.8, and 2.0mm (n=10 each) were prepared from extracted human third molars. After cleaning with EDTA, a mounted specimen was clamped between 2 acrylic chambers attached to both the occlusal

Effect of Tissue Fluids on Hydrophobicity and Adherence of Enterococcus faecalis to Dentin
Journal of Endodontics, 2007This in vitro study was carried out to determine (1) the hydrophobicity of selected oral bacteria, (2) the influence of growth media (saliva and serum) and mode of growth (planktonic or biofilm) on the hydrophobicity of Enterococcus faecalis, and (3) the influence of growth media and conditioning fluids on the adherence of E. faecalis to dentin.

[Effect of phenolic resin fluid on the dentin resistance].
Zhonghua kou qiang yi xue za zhi = Zhonghua kouqiang yixue zazhi = Chinese journal of stomatology, 1991SEM observation was made in the experiment to analyze the ultrastructure of resinified dentin. Phenolic resin fluid permeates in to the dentinal-tubule and set in it. The permeability of this agent was also able to permeate into intercellular substance and changed the appearance of inter-weaved fibril to the condition of agent had set. According to the

Pharmacologic Control of Dentinal Fluid Movement and Dental Caries in Rats
Journal of Dental Research, 1968Parasympathetic stimulants were found to encourage the movement of fluid through the dentin from the pulp to the dentinoenamel junction. Regular treatment with a parasympathetic stimulant in rats that had all their major salivary glands removed significantly reduced the incidence of dental caries.
