Light micrographs of human pulp capped with TDMH A After 2 weeks, scattered fragments of newly formed dentin seen along within the hydrogel, B After 8 weeks, hTDM completely incorporated in the newly formed dentin with numerous visible dentinal tubules. C After 12 weeks, hTDM resorbed during new dentin formation by giant cells with regular odontoblast layer. D After 16 weeks, thick continuous formed dentin completely spanning the distance between the two edges of the exposure site, with normal pulp morphology, × 100.
