The 32 tooth model is a commonly used teaching tool in biology education, which accurately replicates the upper and lower teeth in the adult oral cavity, including different types of teeth such as incisors, canines, bicuspids, and molars, totaling 32 teeth. In biology teaching, this model allows students to intuitively observe and learn the shape, structure, and function of teeth, and understand the important role of teeth in chewing, pronunciation, and facial aesthetics. By splitting and combining models, students can also understand the internal structure of teeth, including enamel, dentin, pulp, etc. In addition, teachers can use this model to demonstrate correct brushing methods and oral hygiene knowledge, helping students realize the importance of protecting dental health.
