This is an update on the present integrated knowledge regarding dentine permeability that assumed a role in dentine sensitivity and contribute clinically to the effective bonding properties of restorative dental materials. This paper will attempt to refer to in vivo and in vitro studies of dentine permeability and the various interrelated factors governing it.

Due to gingival recession both enamel and root dentine are at risk of developing caries. Both tissues are exposed to a similar environment, however there is not a validated model to evaluate the effect of fluoride on these dental substrates simultaneously. Hence, this study aimed to validate a caries model to evaluate the effect of fluoride to prevent demineralization on enamel and root-dentine...

OBJECTIVES There is currently no standardised technique to measure the amount of coronal dentine remaining in a root-treated tooth after crown preparation. The aim of this study was to develop a method of measuring remaining coronal dentine in root-treated teeth and to propose an index for grading tooth restorability. METHODS The study recruited 20 patients who had completed molar endodontic ...

This study was performed to develop alternating dentine adhesion models that could help in the evaluation of a self-bonding dental composite. For this purpose dentine from human and ivory was characterized chemically and microscopically before and after acid etching using Raman and SEM. Mechanical properties of dentine were determined using 3 point bend test. Composite bonding to dentine, with ...

The author examined the ultrastructure and acid phosphatase activity of odontoclasts in physiological root resorption of human deciduous teeth. Extracted teeth undergoing resorption were fixed with a mixture of formaldehyde and glutaraldehyde and processed for scanning (SEM)-and analytical transmission-electron microscopy (STEM). In SEM observation of resorbing dentine surfaces treated with NaO...

In this era of minimal intervention dentistry, the changing concept of cavity preparation and the introduction of reliable adhesive materials have lead to the development of alternative methods of caries removal. Chemo mechanical caries removal (CMCR) involves the chemical softening of the carious dentine, followed by its removal with gentle excavation. This process removes only the infected ti...

During eating, the teeth usually endure the sharply temperature changes because of different foods. It is of importance to investigate the heat transfer and heat dissipation behavior of the dentino-enamel junction (DEJ) of human tooth since dentine and enamel have different thermophysical properties. The spatial and temporal temperature distributions on the enamel, dentine, and pulpal chamber o...

BACKGROUND Diamine silver fluoride (Ag(NH3)2F), referred to as AgF, has been used to reduce the incidence of caries in primary dentitions but has been limited by the associated staining of both teeth and restorative materials. The application of potassium iodide (KI), following AgF prevents staining but its effects on the ability of AgF to reduce caries are not known. The aim of this study was ...

REASONS FOR PERFORMING STUDY There is limited knowledge on the thickness of subocclusal secondary dentine in equine cheek teeth (CT). HYPOTHESES Subocclusal secondary dentine is of consistent thickness above different pulp horns in individual horses and its thickness increases with age. METHODS 408 permanent CT were extracted post mortem from 17 horses aged 4-30 years, with no history of de...

OBJECTIVES The shear bond strength of three glass ionomer cements (GIC) to enamel and dentine was evaluated. STUDY DESIGN Sound permanent human molars (n=12) were grinded perpendicular to their axial axes, exposing smooth, flat enamel and dentine surfaces. The teeth were embedded in resin and conditioned with polyacrylic acid (25%; 10s). Twenty four specimens of each GIC: Fuji IX (FJ-GC), Ket...
