Treatment of dentine hypersensitivity using desensitising toothpastes
… ofoptions for treating the common phenomenon of dentine hypersensitivity (DH) which results from exposed dentine. The first line oftreatment is normally to use a desensitising toothpaste which is a quick, easy and widely available form oftreatment reducing the pain that results from this …

Ionic exchanges between glass ionomers and demineralised dentine
… The infected layer or fully demineralised dentine is removed by dental hand instruments only and glass-ionomer cement is placed to restore the lesion leaving the affected layer or partly demineralised dentine underneath. There are many anecdotal and some published reports of the ability of …

Identification of esters in carious dentine Staining and chemo-mechanical excavation
… products. However, the discoloration of carious dentine is an imprecise indicator of whether or not the dentine is caries free. Other processes might act in concert with the Maillard reactions. This thesis describes how special functional groups formed in the carious process can be used in …

Optical characterisation of the interaction between calcium-silicate based dental restorative materials and dentine
… silicate based dental restorative material (BiodentineTM) with human dentine in comparison with glass ionomer cement, and to investigate its capability to induce dentine remineralisation. Different optical, microscopic, and fluorescent labelling techniques have been applied; such as tandem …

An in vitro study on the effect of organic derived nano hydroxyapatite on dentine permeability
Dentine sensitivity, hinders oral hygiene practices and limits consumption of specific foods and drinks. Studies have shown that, the severity of dentine sensitivity is related to the permeability of dentine tubules such that the more permeable the tubule is the higher the degree of sensitivity. …

Microscopic Sampling of Dentine and Bone Collagen: Development of Sampling Methods for Carbon and Nitrogen Isotope Analysis
Sampling methods for dentine and bone collagen have been evolving for several decades. Incremental dentine collagen sampling and bone collagen sampling have been limited by the available technology throughout that time. As the technology for isotope ratio mass spectrometry analysis improves, the …

The Degradation of Resin Materials Bonded to Dentine in the Root Canal by the Activation of Matrix Metalloproteinases
… in the last two decades, leakage in the resin-dentine interface is still a major limitation of resin based dental restorative materials. Dentine matrix metalloproteinases have been associated with this leakage through their involvement in the proteolytic degradation of the resin-dentine hybrid …

In-vitro assessment of modified resin adhesive-tooth interfaces
… and G-Bond “GB” (GC, UK) and bonded to sound dentine. The inhibitory effect of the modified adhesive on recombinant MMPs and on sound dentine MMPs was assessed using FRET-based measurement of MMP activity and substrate zymography, respectively. Micro-tensile bond strength and …

Hybridisation of dental hard tissues with modified adhesive systems: therapeutic impact of bioactive silicate compounds on bonding to dentine
… technology as well as adhesion testing, about dentine hybridisation and about the drawbacks of contemporary bonding systems. Several studies revealed excellent immediate and short-term bonding effectiveness of etch-and-rinse adhesives, yet substantial reductions in resin- dentine bond strength …

Seen but not heard: Reconstructing the early life history of the Industrial child through carbon and nitrogen stable isotope analysis of dentine collagen
… the child in industrial London using incremental dentine analysis of both adults (survivors) and children (non-survivors) within a single 19th century London burial population to investigate the effects which changing social and economic conditions during Industrialisation had on their diet, …

Tooth wear in Irish teenagers: a laboratory and epidemiological study
… At 16-years-old the prevalence of toothwear with dentine visible was 44%. No difference in salivary flow rates existed. In unstimulated saliva a higher mean, protein carbonyl (p<0.0001) and total calcium concentration (p<0.002) existed for the group with moderate toothwear. In stimulated saliva …

Untersuchung der bakteriziden Wirkung von Nd:YAG-Laserstrahlung am Leitkeim Enterococcus faecalis in bovinem Dentin bei Pulsdauern von 15 und 25 ms : eine In-vitro-Studie
… A total of ninety 500 and 1000 µm thick dentine slices were prepared from bovine incisors. These were inoculated with 1 µl of Enterococcus faecalis suspension of defined concentration on one side in an area with a diameter of 3 mm. After the samples had dried, their uncontaminated side …

The prevalence of caries and tooth wear in cleft children aged between 6 months and 6 years in the West of Scotland.
… When looking specifically at wear extending into dentine, both the 1.5 – 2.49 and 3.5 – 4.49 age groups had significantly more wear when compared to the national data (p ≤ 0.05). Conclusions: By the age of 4.5 years, cleft children in the West of Scotland have significantly more caries than their …
