-
Space is necessary for the proper alignment of the future permanent teeth.
-
It's easier to floss
-
The primary teeth are smaller

Mandibular canines
-
Maxillary centrals
-
Mandibular centrals
-
Mandibular laterals
Correct Answer
A. Mandibular centralsExplanation
The mandibular centrals are the first primary teeth to erupt. This means that they are the first set of front teeth to appear in the lower jaw of a child.Rate this question:

The primary dentition takes how long to be completed?
-
4 to 5 years
-
2 to 3 years
-
1 to 2 years
-
5 to 6 years
Correct Answer
A. 2 to 3 yearsExplanation
The primary dentition, also known as baby teeth, takes approximately 2 to 3 years to be completed. During this time, all 20 primary teeth erupt in the mouth. This process usually begins around 6 months of age and is typically completed by the age of 3. Once the primary dentition is complete, these baby teeth will eventually be replaced by permanent teeth as the child grows.Rate this question:

The enamel and dentin are relatively ___________ than the permanent teeth.
Correct Answer
thinnerExplanation
The enamel and dentin of the permanent teeth are thinner compared to the primary teeth.Rate this question:

Calcification of primary teeth begins in utero at...
-
20 to 25 weeks
-
10 to 15 weeks
-
13 to 16 weeks
-
5 to 7 weeks
Correct Answer
A. 13 to 16 weeksExplanation
Calcification of primary teeth refers to the process of tooth development where the hard tissue of the tooth, known as dentin, begins to form. This process starts in utero, during pregnancy. The correct answer, 13 to 16 weeks, indicates that calcification of primary teeth begins around the 13th to 16th week of pregnancy. At this stage, the tooth buds are forming and the initial stages of dentin formation are taking place. This is an important milestone in dental development as it sets the foundation for the future eruption of primary teeth.Rate this question:

- 7.
The primary tooth crowns are more_____________ at the CEJ, which makes them appear bulbous.
Correct Answer
narrowerExplanation
The primary tooth crowns are narrower at the CEJ, which means that they have a smaller width compared to the rest of the tooth. This narrower shape at the cervical enamel junction (CEJ) gives the appearance of a bulbous shape, as the crown appears wider and more rounded towards the top.Rate this question:
