The diagnosis of occlusal caries at non–cavitated sites remains problematic, especially since clinical visual detection has limited sensitivity. Electrical methods show considerable promise, but specificity is reduced. aims this in vitro study were: (1) to assess the validity a new laser fluorescence device – DIAGNOdent (and compare values with those fixed–frequency electrical device); (2) determine optimum cut–off points for different stages process, and (3) reproducibility device. For...
Children and adolescents must be examined often for occlusal caries. Diagnosis of fissure caries is difficult especially when the tooth surface appears seemingly intact. It has been shown that using traditional clinical methods, as little 20% teeth with under intact surfaces were correctly recognised such. Therefore, new methods increasing accuracy diagnosis have sought years. Recently, a device, based on fluorescence measurements, was introduced. The purpose this study to test device in...
In May 2012, cariologists, dentists, representatives of dental organizations, manufacturers, and third party payers from several countries, met in Philadelphia, Pennsylvania, to define a common mission; goals strategic approaches for caries management the 21th century. The workshop started with an address by Mr. Stanley Bergman, CEO Henry Schein Inc. which focused on imperative change academia, clinical practice, public health. For decades, new scientific evidence how it should be managed...
The International Caries Detection and Assessment System (ICDAS) offers clinical criteria codes, together with a framework to support enable personalized comprehensive caries management for improved long-term health outcome. Based on the ICDAS, this publication provides an up-to-date synthesis of fields detection, assessment, diagnos

Evidence for the effects of low birth weight, breastfeeding and maternal smoking on childhood caries is mainly cross-sectional. We examined association these 3 putative early life factors with increment over a 4-y period among young children. used data from longitudinal caries-risk assessment study carried out Scottish Early were measured when children aged 1 y (baseline). Caries was repeated annually ages to 4, number decayed, missing filled primary tooth surfaces (dmfs) as outcome measure....
Early exposure to sweet tastes predicts similar food preferences and eating behavior in later life is associated with childhood obesity. The aim of this study was explore the associations early (during first year life) subsequent intake sugar-sweetened beverages (SSBs) 4-y caries trajectories among Scottish young children. We used data from 1,111 children who were followed annually age 12 48 mo (4 sweeps total). SSB reported by parents every sweep. broken down into 2 components, initial...
The improvement in the detection of caries offers possibility for dramatic dental healthcare. Current rates suggest that there may be scope improvement. This paper describes a preliminary study to examine applications terahertz pulse imaging (TPI) detection. We present results early stage occlusal enamel layer range human tooth cross sections using TPI. Higher attenuation radiation was observed carious as compared with healthy enamel. Hypomineralised had different absorption spectra and...
Accurate and reliable assessment of caries activity is important for determining appropriate treatment needs. The aim this pilot study was to determine whether dentists could differentiate between the appearances (visual tactile) lesions inactivated by regular professional oral hygiene those control which were not cleaned (active). After a 3- 4-week period involving 10 children, with 4 similar carious each, it found that able reliably reproducibly subtle visual tactile differences active...
Terahertz pulsed imaging (TPI) is a relatively new, non-ionising and non-destructive technique for studying hard tissues which does not require tooth section preparation, unlike transmission microradiography (TMR). If TPI can measure the depths of caries/demineralisation lesions accurately same samples could be reused remeasured during in vitro situ studies on de- and/or remineralisation. The aim this study was to compare TMR measuring range artificially induced bovine enamel demineralised...

Caries diagnosis by the measurement of electrical resistance is hampered polarization effects when dc or single-low-frequency ac currents are used. Electrical impedance spectroscopy, measuring over a large range frequencies, will provide more detailed information about characteristics teeth. It was aim this study (a) to characterize complex behavior whole extracted teeth, measured at approximal surface, and (b) identify parameters teeth which would be useful in distinguishing between degrees...
The aim of this pilot study was to investigate the tooth-brushing behaviour parents and toddlers, by analysis sessions videotaped in families’ homes. Eighteen families (self-selected from an ongoing preventive-intervention study) all home involving their toddler (average age 2.5 years) over a 24-hour period. vast majority (89%) engaged at least two per day, usually supervised mothers. average length 142 s, although brush tended be child’s mouth for less than half that time. On average, only...

A survey types has demonstrated various contrast mechanisms that available in TPI, allowing be readily identified. This encourages pursuit further studies a variety
