This invention proposes a dynamic early warning method for childhood dental caries risk based on multimodal data fusion, relating to the field of image processing technology. The method includes the following steps: Step 1, acquiring oral examination images, saliva biochemical test indicators, and behavioral record data of the target child; Step 2, constructing a dual-branch Kolmogorov-Arnold network comprising tooth position branches, global branches, and a fusion layer. The tooth position branches receive tooth position-level topological feature vectors, the global branches receive child-level global feature vectors, and the fusion layer outputs a predicted dental caries risk value; Step 3, dividing the tooth position samples in the calibration subset into positive and negative calibration groups according to their actual labels, and determining the conformal prediction thresholds for positive and negative groups respectively. This invention achieves a complete closed loop from multimodal data acquisition to dynamic hierarchical early warning, providing reliable technical support for the early identification and precise intervention of childhood dental caries.
