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 …

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 …

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 …

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 …

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, …

An isotopic and historical study of diet and migration during the great Irish Potato famine (1845-1852). High-resolution carbon and nitrogen isotope profiling of teeth to investigate migration and short-term dietary change at the Union workhouse, Kilkenny and Lukin street, London.
… bone collagen ¿13C above -17¿, and incremental dentine collagen demonstrating temporal changes in ¿13C consistent with dietary change from C3 to C4 plants. Bone collagen values for two Lukin Street individuals were consistent with high marine protein consumption. Techniques developed in this …

Fracture resistance of calcium hydroxide-treated teeth filled with water- and PBS-mixed MTA
… in the mechanical properties of radicular dentine after 5 weeks exposure (Yassen & Platt 2013). MTA may increase the resistance to vertical root fracture of endodntically treated teeth treated in one-visit (EL-Ma'aita et al. 2014).<b><br/></b><b><br/></b><b>Aim</b>: To test, in vitro, the …

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 …

Peptide hydrogels as novel scaffolds for dental pulp cell culture
… and/or growth factors for regeneration of the dentine-pulp complex. <br/><br/>In this project, the viability of DPCs was determined in vitro with inhouse synthesised ultrashort peptide hydrogels (NapFFKK-OH and NapFFK’K’-OH) as well as commercially available Biogelx hydrogels containing …

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 …

Healing Processes of Periapical Endodontic Leasions after Retrograde Filling // Оздравителни процеси на периапикални възпалителни изменения от ендодонтски произход след ретроградно запълване
… The apical resection ends with an exposed apical dentine surface which is why it is sometimes necessary to perform a retrograde cavity for a retrograde filling. Surgical endodontic therapy is the treatment of choice when teeth have responded poorly, when inadequate instrumentation is met and teeth …

Development of methodologies for the assessment of oral prostheses.
… The material used as a substitute for dentine was beechwood which has mechanical and granular properties similar to dentine. The mode of fatigue loading has been combined direct shear, torsion and bending. Finite clement techniques have been deployed and used qualitatively to gain an …

Molecular characterisation of odontoblast during primary, secondary and tertiary dentinogenesis. Caractérisation moléculaire de l’odontoblaste au cours des dentinogénèses primaire, secondaire et tertiaire.
… common regulatory processes may exist between dentine and bone. The p38 gene was shown to be highly expressed in odontoblasts during active primary dentinogenesis, but was drastically down-regulated as cells become quiescent in secondary dentinogenesis. Based on the hypothesis that parallels …
