2) Cystic transformation occurs owing to inflammatory stimulation of the epithelial rests of Malassez in the periodontal ligament, secondary to a root canal infection, in which the bacteria and their products, that were previously confined to the dental pulp, go beyond the root canal system and reach the periapical tissues.
However, since the epithelial rests of Malassez are embedded in the periodontal ligament, consequently making it difficult to isolate and/or manipulate Malassez epithelium both in vitro and in vivo, no firm evidence has been obtained to support their functional role.
It is possible that cementum might also contain putative molecules that regulate the periodontal space width along with the epithelial rests of Malassez.
