how do dental formula of humans help us?
Answers
Answer:
A dental formula is a system for summarizing the number of each type of tooth (incisor, canine, premolar, molar) in each quadrant of the mouth. Dental formulae vary between species and may be different for the maxillary and mandibular dentition. For example, the dental formula for a dog is 3142/3143 (upper/lower dentition), indicating that there is an additional molar in the mandible compared to the maxilla. In humans, the deciduous dentition consists of 20 total teeth, with the dental formula 2102/2102, indicating two incisors, one canine, zero premolars, and two molars in each quadrant. The permanent dentition consists of 32 teeth in total, with the dental formula 2123/2123, indicating two incisors, one canine, two premolars, and three molars in each quadrant.
