Microphotographs of a longitudinal H&E-stained section through central incisor after one week of ESRRM putty treatment. (a–c) The ESRRM putty (blue left-right arrow) surrounded by and incorporating mineralized deposition pulpal tissue contained a few long dilated and congested blood vessels, and an irregular deposition of reparative dentine (quad arrow) was seen adjacent to multilayers of short odontoblasts ((a) 40X; (b-c) 100X). d: The periodontal ligament had dense fiber bundles running parallel to the root surface and inserted in the newly formed bone with minimum congested capillaries with no inflammatory cells infiltration (100X). The gap in the alveolar bone was filled with irregular and small bone trabeculae (black curved-up arrow).
