Abstract

The DIAGNOdent^[○!R], a new device for diagnosing caries using a semiconductor laser, has been shown to have the ability to detect even small carious lesions in a non-destructive manner, and is therefore expected to be useful for the diagnosis of incipient caries or preclinical caries. A few reports have indeed been published on the usefulness of DIAGNOdent^[○!R] in the clinical diagnosis of caries. However, its usefulness for perceiving the presence or absence of a feeling of stickiness in pits and fissures has not been studied to date. Determination of the presence or absence of a feeling of stickiness in the teeth has been considered to be useful for determining whether or not aggressive preventive measures against caries, such as the use of sealants, are indicated. However, the use of a dental probe to assess such stickiness is associated with problems. Accordingly, we conducted a clinical epidemiological study of elementary school children to examine the usefulness of the DIAGNOdent^[○!R] for assessing the stickiness of teeth and establishing criteria for the diagnosis. The kappa value, which indicates the correspondence between the presence or absence of stickiness and the DIAGNOdent^[○!R] values, was the highest (0.49, indicative of a moderate correspondence ratio) when the DIAGNOdent^[○!R] value of 20 was used as the cutoff point. Using the same cutoff point, the sensitivity was 0.78, the specificity was 0.74, the predictive value for positive responses was 60% and the predictive value for negative responses was 87%. Thus, a relatively high efficacy of DIAGNOdent^[○!R] for detecting healthy teeth with no stickiness was demonstrated.
