How many teeth are in deciduous dentition?

Explanation

Answer: B - There are 20 teeth in deciduous dentition. These teeth are similar to adult teeth, except that they are smaller. The molars are wider than the premolars that replace them, but are smaller than permanent molars. Primary teeth are also whiter, the crowns are shorter, and the roots are slender and longer than in permanent teeth.
