Ringkasan :
It is not generally possible to assess diagnostic accuracy in dental surveys as no histological ‘gold standards’ are available, therefore examiner agreement tends to be used as a proxy for accuracy. The aim of this study was to investigate, using extracted teeth in arch models, the in vitro validity of a diagnostic system to assess caries at the D1 (enamel and dentine) and D3 (dentine) diagnostic thresholds, for epidemiological purposes. Method: Two groups of 10 dental examiners trained in the use of the Dundee Selectable Threshold Method for caries diagnosis (DSTM) each examined (on two occasions) 160 extracted permanent molar and premolar teeth set in arch models in phantom heads according to the codes and criteria of the DSTM. The teeth were subsequently radiographed and sectioned to provide validation of the diagnoses.
