In vivo validation of Diagnodent and Vista proof devices vs ICDAS clinical criteria on incipient carious lesions in adults

AIM

This study aimed to validate the in vivo performance of Diagnodent and Vista proof devices with ICDAS clinical criteria on incipient carious lesions in adults.

METHODS

A total of 44 adult patients with 230 incipient occlusal caries took part in the present study. These patients were assessed for caries with ICDAS clinical criteria, and then they were examined with Diagnodent pen™ (DP) and Vista proof™ (VP) fluorescence devices. Sensitivity, specificity accuracy, and ICC agreement between devices with ICDAS criteria, which served as a gold standard, were evaluated.

RESULTS

Regarding the caries diagnostic devices, sensitivity and specificity found 0,61 and 0,51 for DP, and 0,64 and 0,54 for VP, respectively. The different detection methods showed no differences in diagnostic capacity (Az values) each other, and ICC values with ICDAS criteria were calculated low.

CONCLUSIONS

DP and VP do not contribute to incipient occlusal carious lesions' better detective ability compared with visual ICDAS clinical criteria. The DP and VP devices presented no differences in diagnostic ability and measured lesion depth concerning the visual examination.

Clinical Evaluation of Two Different Prevention Programs in Adults Depending on Their Caries Risk Profile: One-year Results

The aim of this study was to investigate the management of incipient caries lesions in adults with two preventive protocols. A total of 44 adult patients with high, moderate and low caries risk with 516 incipient caries took part in the study. These patients were assessed for caries with International Caries Detection and Assessment System (ICDAS) criteria and were then divided into three groups depending on their caries risk profile: a high-risk group (group A), a moderate-risk group (group B), and a low-risk group (group C). Participants in each group were further divided randomly into two subgroups. In subgroups A1, B1, and C1, an intensive preventive protocol was applied, while in subgroups A2, B2, and C2, the protocol consisted only of instructions in oral hygiene. The invasive-intensive protocol included the topical application of fluoride, brushing with 5000-ppm fluoride toothpaste, use of amorphous calcium phosphate-casein phosphopeptide, applications of sealants for occlusal lesions (ICDAS code 2), and minimal resin restorations for occlusal lesions (ICDAS code 3). There was no statistically significant difference in the number of lesions (baseline and after one year) in the high-risk and moderate-risk groups that received the intensive protocol (groups A1 and B1), while the control groups were statistically significant different (groups A2 and B2). In the low-risk group, there was no statistically significant difference in the number of lesions (groups C1 and C2). The two different preventive protocols in the high- and moderate-risk groups presented differences in effectiveness, while in the low-risk group, no significant difference was demonstrated.
