Which type of resorption is most commonly associated with the replantation of teeth?

External resorption is the type of resorption most commonly associated with the replantation of teeth. This condition occurs when the outer surface of the tooth root begins to break down and is typically linked to factors such as trauma, inflammation, or the process of replanting a tooth after it has been avulsed. During replantation, various biological responses can lead to the activation of resorptive processes, where the body responds to the trauma in an attempt to repair or adapt to the presence of the tooth. This often results in the external surface of the root being affected first.

While internal resorption involves the breakdown of the tooth structure from within, it is not the prevalent type seen after replantation. Bone resorption pertains to the loss of bone mass and does not specifically refer to the tooth structure itself. Root resorption is a broader term that can encompass resorption occurring on either the internal or external aspects of the root, but in the context of replantation, it is the external aspect that is typically of greater significance. Thus, the correct answer highlights the importance of understanding the specific processes that occur following the replantation of a tooth.
