Abstract: An imaging support device that supports imaging of teeth inside an oral cavity is provided. The imaging support device includes an input unit, an identification unit, a specification unit, and an output unit. The input unit receives a tooth image obtained by imaging the teeth inside the oral cavity. The identification unit identifies a type of a tooth based on the tooth image received by the input unit. Based on the type of the tooth identified by the identification unit, the specification unit specifies a type of a tooth as a target for imaging support. The output unit outputs information about the type of the tooth specified by the specification unit to an outside at a prescribed timing.

Abstract: An identification device that identifies a type of a tooth includes: an input unit that receives three-dimensional data including three-dimensional position information at each of a plurality of points forming the tooth; an identification unit that identifies a type of the tooth based on the three-dimensional data received by the input unit and an estimation model including a neural network; and an output unit that outputs an identification result obtained by the identification unit. The identification unit directly inputs the three-dimensional position information included in the three-dimensional data received by the input unit to the neural network included in the estimation model.

Abstract: A handheld dental instrument includes a casing provided with a holding portion to be held by a user, a reception unit provided on the casing to receive an operation from the user, and a control unit that controls a control target to perform a predetermined action in response to the operation received by the reception unit. The control unit performs a first control when the operation received by the reception unit from the user is a first operation, and performs a second control different from the first control when the operation received by the reception unit from the user is a second operation different from the first operation.

Abstract: A magnifying glass captures an image of a tooth by a plurality of cameras for observation. The plurality of cameras includes a narrow range camera capturing a narrow range image of the tooth and a wide range camera capturing a wide range image of the tooth. The magnifying glass includes a three-dimensional position calculator detecting a three-dimensional position of at least the tooth based on the wide range image; a blur correction processor correcting a blur of the narrow range image, based on a change in a three-dimensional positional relationship between the tooth, the three-dimensional position of which has been detected by the three-dimensional position detector, and the narrow range camera; and an image display portion displaying at least the narrow range image having the blur corrected.

Abstract: The present disclosure relates to an image capturing device configured to capture an image of a target. The image capturing device includes a probe and a housing. The probe includes an optical component and is configured to receive light from the target. The housing includes electronic components each configured to process the light received from the probe. Moreover, the housing includes an air sending unit, and a controller configured to control driving of the air sending unit. The air sending unit is provided at a position above the electronic components in the housing when a user holds the housing during utilization of the image capturing device, and is configured to supply air to the optical component provided in the probe.
