Abstract: Disclosed are a system and a method for providing nutritional information based on image analysis using artificial intelligence. The system includes: at least one imaging device acquiring at least one image including at least one dish or at least one food contained in each dish; a service providing apparatus for detecting at least one food included in the at least one image when the at least one image is received, confirming the name of each detected food on the basis of a learning model, mapping food information included in pre-stored food information on the basis of the confirmed name, and generating nutritional information using the mapped food information; and a user terminal for visualizing and displaying the nutritional information when the nutritional information is received.

Abstract: Various implementations include a dental suction device configured to be disposed on a toothbrush having at least one bristle head. The dental suction device includes a main conduit, at least one pair of secondary conduits, and a shaft. The main conduit includes a first end and a second end spaced apart from the first end. Each of the secondary conduits includes a first end and a second end spaced apart from the first end. The first end of each of the secondary conduits is connected in fluid communication with the main conduit. The shaft is coupled to and disposed between the pair of secondary conduits. The shaft is shaped to receive and retain a portion of the toothbrush in between the pair of secondary conduits such that the pair of secondary conduits is configured to apply suction at least subjacent the bristle head.
