Periodontics is the dental specialty focusing exclusively in the inflammatory disease that destroys the gums and other supporting structures around the teeth. A periodontist is a dentist who specializes in the prevention, diagnosis, and treatment of periodontal, or disease, and in the placement of dental implants.

Gingivitis is a common and mild form of gum disease (periodontal disease) that causes irritation, redness and swelling (inflammation) of your gingiva, the part of your gum around the base of your teeth. It’s important to take gingivitis seriously and treat it promptly.

Gingiva prepares and protects itself from various pathogens, through the fine tuning of homeostasis. If this balance is lost, the acti- vity of gingival tissue becomes abnormal, and this change is perceived as periodontal disease.
Gingival crevicular fluid (GCF) is an inflammatory exudate derived from the periodontal tissues. It is composed of serum and locally generated materials such as tissue breakdown products, inflammatory mediators, and antibodies directed against dental plaque bacteria.
