What is the minimum opening required for pulp revascularization?

The minimum opening required for pulp revascularization is 1 mm. This size is critical as it allows sufficient access and facilitates the tissue regeneration process necessary for revascularization. The 1 mm opening is large enough to enable the adequate placement of regenerative materials and the delivery of vital nutrients and signaling molecules to the damaged pulpal tissue.

Additionally, a larger opening might lead to an increased risk of bacterial ingress, which can compromise the healing process, while a smaller opening may not provide enough space for effective treatment. Thus, the 1 mm threshold balances effective access for intervention while minimizing potential complications related to infection and ensuring that the biological processes of healing can occur efficiently.
