“…The performance was similar to that found in a recently published in vitro study in deciduous teeth [Attril and Ashley, 2001] as well as in in vitro and in vivo studies in permanent teeth [Lussi et al, 1999[Lussi et al, , 2001Shi et al, 2000]. Permanent and deciduous teeth have different macro-and micromorphological characteristics [Skalerič et al, 1982;Shellis, 1984;Wilson and Beynon, 1989]. These differences could also affect their physical properties and hence the performance of the laser system, e.g.…”

The aim of this study was to compare, in vitro, the performance of different conventional diagnostic techniques with the laser-based device, DIAGNOdent, for diagnosis of occlusal caries in deciduous teeth. 95 deciduous teeth with macroscopically intact occlusal surfaces were selected. All teeth were assessed by the following techniques: visual inspection (VI), visual inspection with magnification (VIM), visual inspection combined with light pressure probing (VIP), bitewing radiography (BW) and the DIAGNOdent (DD). Caries extension was assessed by histology. DIAGNOdent showed, in comparison with the conventional clinical methods, a significantly improved ability (p < 0.05) to detect dentinal lesions (D₃ or D₄) in deciduous teeth and an overall performance similar to that obtained in previous studies on permanent teeth. There was no statistically significant difference between VIM and DD in detecting caries confined to enamel (D₂). DD performed better at D₂ level than the other methods. The intraexaminer kappa scores for DIAGNOdent were 0.76–0.86 (D₂) and 0.77–0.85 (D₃), respectively. It was concluded that DIAGNOdent could be used as an additional tool in the detection of occlusal caries in deciduous teeth and its good reproducibility should enable the laser device to monitor the caries process over time.

“…In comparison with permanent enamel, primary enamel is less mineralized and more porous. Consequently, the diffusion coefficient seems to be greater in primary than in permanent enamel 27,28 . Moreover, a lower mineralized and thinner surface layer was observed in proximal enamel lesions in primary molars compared with permanent ones 25 …”

“…Consequently, the diffusion coefficient seems to be greater in primary than in permanent enamel. 27,28 Moreover, a lower mineralized and thinner surface layer was observed in proximal enamel lesions in primary molars compared with permanent ones. 25 Despite of the better penetration of primary compared with permanent caries lesions after 1-min application and the relatively high percentage penetration found, one should be cautious to recommend this application time for clinical infiltration in young children.…”

“…As a consequence, their crowns appear whiter in color. The ordering of the crystallites is probably poorer in milk teeth than in permanent ones (Skaleric et al, 1982). Primary and mature enamels are similar in terms of amino acid composition, except the latter contains more glycine (Wright et al, 1997).…”

“…Furthermore, as has been widely illustrated in the previous chapters, many carbonate-derived signals look "similar", but may, in fact, have significantly different properties. Skaleric et al (1982) observed that signals of enamel plates from deciduous teeth exhibited a weaker EPR signal anisotropy than signals of plates from permanent teeth. They concluded that the degree of microcrystal arrangement in deciduous teeth is lower.…”

When tooth enamel is exposed to ionizing radiation, radicals are formed that can be detected using Electron Paramagnetic Resonance (EPR) techniques. EPR dosimetry using tooth enamel is based on the (presumed) correlation between the intensity or amplitude of some of the radiation-induced signals with the dose absorbed in the enamel. In the present paper a critical review is given of this widely applied dosimetric method.The first part of the paper is quite fundamental and deals with the main properties of tooth enamel and several of its model systems (e.g., synthetic apatites). Considerable attention is also devoted to the numerous radiation-induced and native EPR signals, and the radicals responsible for them. The relevant EPR detection, identification and spectrum analysing methods are reviewed from a general point of view. Finally, the need for solid state modelling and the linearity of the dose response are investigated.The second part is devoted to the practical implementation of EPR dosimetry using enamel. It concerns the preparation of samples, specific irradiation problems, spectrum acquisition and it is described how the dosimetric signal intensity and dose can be retrieved from the EPR spectra. Special attention is paid to the energy dependence of the EPR response and to sources of uncertainties. Results of and problems encountered in international intercomparisons and epidemiological studies are also dealt with.In the final chapter the future of EPR dosimetry with tooth enamel is analysed.
