MICROANATOMY

Detailed explanation-1: -Each of the primary molars is replaced by permanent, premolar teeth. There are three permanent molars in each quadrant that are not succeeded by primary teeth and may be referred to as non-succedaneous teeth.

Detailed explanation-2: -Permanent maxillary and mandibular first molars are the first permanent teeth to erupt into the oral cavity along with the mandibular incisors. It serves as an excellent record of maternal and fetal health, reflecting the prenatal, perinatal, and postnatal health and diseases.

Detailed explanation-3: -These baby molars are eventually replaced by bicuspids or premolars. Unlike canines and incisors, premolars feature a flat biting surface and are responsible for chewing and grinding food. In most cases, the first premolars appear at age 10 while the second ones make their debut approximately a year later.

Detailed explanation-4: -The primary (deciduous or milk) dentition comprises four incisors, two canines, and four molars in each jaw (total of 20 teeth). The normal permanent (adult) dentition comprises four incisors, two canines, four premolars, and six molars in each jaw (32 teeth).
