(2) all premolors
(3) first two molors
(4) all premolor and molor​

Answer 1

The Deciduous dentition of a seven-year-old girl child lacks all molars. (option 1)

• The basic dental formula of a baby is 2102/2102.
• Where the first four numbers indicate half of the upper mandible, and the second four numbers indicate half of the lower jaw.
• The series fllows as: Incisors, canine, molar and premolar.
• Thus molars are absent in a child of seven years.
• The deciduous dentition represents the dentition of a child. As those teeth fall during a certain age and new teeth erupt.
• Thus for this question, option 1 is much more appropriate.

Answer 2

Answer:

All premolars are absent in deciduous dentition.

Explanation:

• One of the strongest organs in the human body is the tooth. It mostly consists of minerals and proteins (collagen) (calcium). In addition to aiding in digestion, teeth are crucial for communication.
• 32 teeth, including the wisdom teeth, make up an adult's mouth. The majority of adults will have their entire set of permanent teeth in place by the time they turn 21. Molars are the first permanent teeth to erupt.
• Babies are born without teeth since their main source of nutrition is breast milk. Milk teeth progressively begin to erupt as the infants begin to wean. By the time a person reaches the age of six, their milk teeth have been replaced by their permanent teeth.
