This invention discloses a disinfection device and method for dental examination instruments, relating to the field of dental examination instrument disinfection technology. The device includes a cabinet with an ultrasonic disinfection tank on its inner side. One side of the inner wall of the ultrasonic disinfection tank has an inclined flushing pipe. A horizontal component is located on the inner side of the cabinet, and a vertical component is located on the outer side of the horizontal component. A disinfection basket is movably connected to the vertical component via a fixing component. An inclined perforated plate is fixedly installed on the inner side of the disinfection basket, and a placement rack is fixedly installed on the top of the inclined perforated plate. A limiting component is located on the top of the placement rack, and a rotating component is located on the inner side of the cabinet. By utilizing the limiting component, this invention allows for easy adjustment of one end of controlled instruments of different specifications to the same horizontal level, facilitating the flushing of the inner wall of the controlled instruments by the inclined flushing pipe on the ultrasonic disinfection tank. This process completes the entire disinfection and flushing of dental examination instruments without manual intervention, greatly facilitating operation and use by dental professionals.

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.

This invention provides an oral examination device for dentistry, belonging to the technical field of oral examination for dentistry. The device includes a base, a seat plate mounted on the top surface of the base, a reclining board mounted on one side of the top surface of the seat plate, and a mouthwash assembly mounted on the rear side of the top surface of the base. An L-shaped rod is fixedly connected to the mouthwash assembly, one end of the L-shaped rod is rotatably connected to a crossbar, and one end of the crossbar is hinged to a lighting lamp. This invention, by setting up the mounting plate and two arc-shaped support plates, can support the patient's upper and lower lips, thus facilitating better mouth opening for oral examination by medical staff. By adjusting the components, the distance between the two arc-shaped support plates can be adjusted to meet the needs of different patients, improving the applicability of the device. Through the cooperation of the flexible rod and the camera, the internal oral environment can be monitored in real time, allowing medical staff to better examine the oral cavity and improving the efficiency of oral examinations.
