Gingival overgrowth is one of the side-
effects seen as a result of the regular administration of the
calcium channel blocker anti-hypertensive drug Nifedipine.
Fibronectin (FN), is an adhesive high molecular weight extra
cellular matrix glycoprotein which plays an important role in
influencing cell growth, adhesion, migration as well as

fibroblast attachment and proliferation, and participates in
the regulation of tissue fibrosis. Erbium: YAG laser was
approved in 1997 by the U.S. Food and Drug Administration

have been published to demonstrate its efficacy for bone

having an antiseptic effect on both soft and hard periodontal
tissues. Conventional scaling in combination with Erbium:
