: Areca caused no significant effect on the morphology of the gingival epithelium
, no disorganization of prickle cell layer (Fig.
The gingival epithelium
as well as connective tissue have a very high turnover rate and new cells are constantly produced to replace cells, which are lost through cell death or migration.
Damaged gingival epithelium
(GE) was assessed by light microscopy and quantified by a histological score (values 1-4).
In GTR procedure use of barriers exclude gingival epithelium
and connective tissue from the root surface, which hinders regeneration, stabilize blood clot, maintain space where regenerative tissues may form and allow time for new connective tissue attachment to become established on root surface.
In regard to the highly specified cell-to-cell junctions and high renewal capabilities, gingival epithelium
is considered a strong but passive barrier against the bacterial challenge that is constantly present in the oral cavity.
Smoking influences on the thickness of marginal gingival epithelium
9) The depigmentation procedure involves scalpel and blade surgical technique to remove or peel off the gingival epithelium
layer and new epithelium layer is allowed to form by secondary healing which was devoid of pigmentation (10) Scalpel deepithelization is simple and inexpensive and does not require any sophisticated armamenerium and is easy to perform.
