Why does calcium hydroxide causes internal resorption in primary teeth?

Calcium hydroxide (CaOH) is customarily used for permanent teeth but not for deciduous dentition because it is known to cause internal resorption in the latter. The loss of protective layer of predentin over mineralized dentin may also make the primary tooth more susceptible to resorption.
The two most important reasons for using CaH in endodontics are its antimicrobial effect and the potential to stimulate mineralized repair of pulp and periapical tissues. However, the usage of calcium hydroxide is not routinely recommended for primary dentition because its application frequently results in the development of chronic pulpal inflammation and internal root resorption.
When CaOH is placed in permanent teeth, it results in calcific (dentin) bridge formation, but in primary teeth it is likely to cause internal resorption. Though various theories have been proposed and suggested to elucidate this phenomenon, the exact mechanism continues to be obscure.
