“…In agreement with this finding are the recent results of Van der Laan et al [1986] who demonstrated enhanced mineral loss underneath artificial fissures where probe damage was initiated. Another method for clinically assessing the mineral content of white spot areas may be the measure of electrical conductivity where the chances of explorer damage are eliminated [White et al, 1978].…”

Kinetic and Physical Aspects of Enamel Remineralization – A Constant Composition Study

1988

The constant composition crystallization technique has been used in conjunction with surface hardness and radiographic methods to investigate kinetic and physical aspects of remineralization of artificial carious lesions in bovine enamel in vitro. The kinetic data indicate that the remineralization of surface-softened enamel occurs more rapidly than that in subsurface demineralized white spots. The remineralization of all types of artificial lesions is associated with considerable surface rehardening. For shallow lesions, the relationship between surface hardening and remineralization is linear, however, this correlation breaks down in more advanced lesions. Importantly, the maximum rehardening of carious lesions appears to be related to their initial degree of acid demineralization.

“…The more demineralized the tissue, the lower the resistance becomes. Site-specific measurements have been evaluated in a number of in vitro studies [45][46][47][48] and in vivo studies. 49,50 Surface-specific electrical conductance measurements have been investigated under in vitro conditions, 51 which showed moderate sensitivity and specificity.…”

“…less complicated machine, was of Japanese origin and called the Caries Meter L (G-C International Corp. Re search Park, Leuven, Belgium). Both machines showed great potential for occlusal caries detection [White et al, 1978;Sawadaetal.. 1986]. Monitoring the progress or arrest of occlusal lesions was also shown to be possible using the Vanguard [White et al, 1981].…”

Histological Validation of Electrical Resistance Measurements in the Diagnosis of Occlusal Caries

et al. 1996

View full text Add to dashboard Cite

Diagnosis of occlusal caries is difficult from visual and radiographic examination. The use of electrical resistance measurement has been described previously and reported to be a potentially sensitive alternative technique. This is possibly due to the decreased resistance of carious pits and fissures. The aim of this study was to validate a prototype electrical caries monitor for the diagnosis of caries in pits and fissures in vitro using a microfocal radiographic technique. Thirty discrete sites were investigated in 10 extracted molar teeth. Electrical resistance measurements were recorded at each site and thick sections (approximately 0.65 mm) prepared for microfocal radiography. Microfocal radiography indicated that six sites were sound, 10 had enamel caries and 14 dentine caries. At a resistance value of 2.2 MΩ, below which a site was regarded as carious and above which it was regarded as sound, electrical resistance measurements proved sensitive (92%) and specific (100%). Quantification of mineral content indicated that mineral loss in enamel may influence resistance measurement more than lesion depth.

Early Detection of Occlusal Caries by Measuring the Electrical Resistance of the Tooth

Abstract: The tooth resistance measuring instrument was compared to the traditional method of the explorer examination for the detection of occlusal carious lesions. The findings of the instrument were more sensitive as compared to the traditional method when verified by a histological examination.
