Propagation of Light through Human Dental Enamel and Dentine

Jaap Vaarkamp, J.J. ten Bosch, Emiel H. Verdonschot

Techniques based on transillumination of teeth with visible light will be a valuable aid in caries diagnosis, if a higher sensitivity than that of the present Foti method is achieved. Therefore, a better understanding of light propagation through teeth is required, and …

Factors Involved in Validity Measurements of Diagnostic Tests for Approximal Caries – A Meta-Analysis

H.M. van Rijkom, Emiel H. Verdonschot

In this study, a meta-analysis was performed on published validity parameters of visual inspection, radiographic examination and visual inspection upon fibreoptic transillumination (FOTI) in approximal caries diagnosis. It was the objective to investigate the influence of the diagnostic test, the study design …

Impact of the Validator and the Validation Method on the Outcome of Occlusal Caries Diagnosis

Ann Wenzel, Emiel H. Verdonschot, Gerrit Jan Truin, K.G. König

In studies evaluating the performance of caries-diagnostic methods, a validation of the true state of disease is needed. The aim of this study was to evaluate the impact of the validator and the validation system (stereomicroscopy or radiography of tooth sections) on …

Electrical Conductance of Fissure Enamel in Recently Erupted Molar Teeth as Related to Caries Status

Y.L. Ie, Emiel H. Verdonschot, M.J.M. Schaeken, M. A. vanʼt Hof

Pit-and-fissure caries lesions contribute greatly to the caries incidence in permanent molar teeth in children. To date, the diagnosis of occlusal caries is still performed mainly by visual inspection, periodically aided by bite-wing radiography. However, in detecting small occlusal carious lesions, these …

Wavelength-Dependent Fibre-Optic Transillumination of Small Approximal Caries Lesions: The Use of a Dye, and a Comparison to Bitewing Radiography

Jaap Vaarkamp, J.J. ten Bosch, Emiel H. Verdonschot, M.C.D.N.J.M. Huysmans

The mere detection of caries lesions is insufficient for optimal treatment decision-making. Hence, the aim of this study was to investigate whether quantitative information about approximal lesion depth can be obtained from a technique based on the wavelength dependency of light propagation …

Validity of Electrical Conductance Measurements in Evaluating the Marginal Integrity of Sealant Restorations

Emiel H. Verdonschot, P. Rondel, M.C.D.N.J.M. Huysmans

The use of sealants and sealant restorations has increased considerably over the past 10 years, and with it increased the problem of detecting secondary caries and marginal (micro)leakage. It was the purpose of this study to investigate the validity of electrical conductance …

Electrical Conductance and Electrode Area on Sound Smooth Enamel in Extracted Teeth

M.C.D.N.J.M. Huysmans, Emiel H. Verdonschot, P. Rondel

Electrical conductance measurements are being used experimentally to diagnose caries. Current equipment, e.g. the electronic caries monitor (ECM), uses a probe to scan occlusal fissures. For full-mouth examination this method is rather time-consuming. A method with which only one measurement is needed …
