which of the following is a biochemical mediator that causes extensive collagen destruction of the periodontal tissues? group of answer choices a) cytokines b) recombinant monokines c) prostaglandins of the e series (pge) d) matrix metalloproteinases (mmps)



Answer :

The biochemical mediator that causes extensive collagen destruction of the periodontal tissues is known as Matrix metalloproteinases (MMPs), which means option D is correct.

Collagen is the most abundant connective tissue present in human body which is an essential part of bones, tissues, muscles, cartilage etc. Periodontal tissues are the tissues found between cementum and alveolar bone of the tooth which helps it to bind the tooth firmly.

Matric Metalloproteinases are the essential enzymes whose main functions are normal tissue remodeling, quick wound healing, and angiogenesis (production of new blood vessels). They are produced by many kind of cells but are activated mainly by macrophages. They cause damage to the periodontal tissues by damaging the collagen.
