The purpose of this study was to determine predoctoral dental student evaluation of the American Academy of Pediatric Dentistry's Caries-Risk Assessment Tool (CAT) for children. Dental students were introduced to the CAT instrument as part of their didactic pediatric dentistry curriculum. These students were later encouraged to use the CAT instrument for determining caries risk in their pediatric patients. Following a two-year exposure to the CAT instrument, dental students completed an anonymous seven-item evaluation of the instrument at the end of their primary clinical experience in pediatric dentistry. The students were asked to score each item on a five-point scale ranging from strongly agree (#5) to neutral (#3) to strongly disagree (#1). Ninety-seven percent of eligible students completed the CAT evaluation questionnaire. Most students agreed that the CAT instrument was easy to understand (86 percent), simple to apply (76 percent), useful for prescribing radiographs (76 percent), and useful for determining preventive procedures (84 percent). Eighty percent of them indicated that they were likely to use the CAT instrument in their clinical practice. In conclusion, student acceptance of the CAT instrument indicates that it may educate predoctoral dental students regarding caries risk assessment in children.
