The primary teeth begin to erupt at 6 months of age. The permanent dentition is composed of 32 teeth with 16 in each arch. There are eight teeth in each quadrant, composed of two incisors (central and lateral), a canine, two premolars, and three molars.
There are five teeth in each quadrant, composed of two incisors (central and lateral), a canine, and two molars. These teeth are referred to as letters A, B, C, D and E. The primary teeth begin to erupt at 6 months of age. The permanent dentition is composed of 32 teeth with 16 in each arch.
GENERAL DIFFERENCES No. of teeth present:- primary-20 permanent – 28-32 Teeth formula:- ICPM/ICPM primary- 2102/2102 permanent- 2123/2123 Bicuspids and third molars are absent in the primary set of tooth. Primary teeth are smaller in size when compare to permanent teeth. 1st tooth to erupt into the oral cavity is mandibular incisor whereas in permanent teeth it is the mandibular first molar. Primate space is absent...
Usually, there are
20 primary ("baby") teeth and 32 permanent teeth, the last four being third molars or "wisdom teeth", each of which may or may not grow in. Among primary teeth, 10 usually are found in the maxilla (upper jaw) and the other 10 in the mandible (lower jaw).The permanent dentition is comprised of
32 teeth. There are 16 teeth in the maxilla and 16 in the mandible. In each arch there are two central incisors, two lateral incisors, two canines, four premolars, and six molars. The permanent central incisors, lateral incisors, canines, and first and second premolars replace the primary dentition.
The human dentition is composed of two sets of teeth – primary and permanent. Teeth are organised into two opposing arches – maxillary (upper) and mandibular (lower). These can be divided down the midline (mid-sagittal plane) into left and right halves.
