PATHOLOGY

Detailed explanation-1: -Surface epithelialization is complete by 5-14 days. In 3-4 weeks: Complete epithelial repair takes place.

Detailed explanation-2: -1) After scaling and root planing, there is reestablishment of the junctional epithelium to the tooth surface in 1 to 2 weeks; reevaluation before 2 weeks is too early. 2) After scaling and root planing, the repair of connective tissue continues for 4 to 8 weeks.

Detailed explanation-3: -On the other hand, keratinocytes migrate and proliferate at the edge of the wound to extend the newly formed epithelial carpet made of several layers of cells in the epidermis. This process is called re-epithelialization and it lasts for two to three weeks.

Detailed explanation-4: -The first phase: 4-16 weeks, whereas remodeling process-4 to 12 months or longer in humans. Thus, complete healing probably takes longer than 3 to six months. [21] The epithelial and connective tissue healing following electrosurgical incisions in human gingiva found that: At 3rd day: Epithelial closure is complete.

Detailed explanation-5: -hemostasis and coagulation, 2. inflammation, 3. cell proliferation, and 4. wound remodeling and maturation.
