... microbial control and dentin conditioning would be responsible for the healing process in REPs, considering that a 5-log reduction in bacterial number (99.999%) is necessary for the root canal microenvironment to be conducive to pulp regeneration [ Figure 1]. [15] The results determined that 2/18 cases failed by the persistence of infection and the appearance of external inflammatory resorption [ Figure 2]. Therefore, if 89% of the cases had a periapical repair, it is suggested that NaOCl, EDTA, tri, or dual antibiotic paste, or Ca (OH) 2 , controlled the microbiological factor plausibly. ...
