Question

describe the process of periodontal regeneration, including the type and origin of cells involved in the regenerative process.

Answer 1

DU Healing by second intention - It occurs in Surgital wounds that left to heal without appooximating the edges. Healing by third intention - Healing by contraction Of wound edges and also the precence of foreign i particle ed infection suspected.
