Resorbability of the roots of primary dentition is explained by: (A) Genetically determined, (B) Pressure applied by successors, (C) Both 1 and 2, (D) None
Answer is C. Resorbability of the roots depends on both the above factors.
If there is no successor of primary tooth then it function as a permanent tooth and its root does nor resorb which indicates that its dependency on pressure applied by successor. It also depends on the genetic factors.
