Periodontal disease includes gingivitis and periodontitis “Gingivitis is generally regarded as a site‐specific inflammatory condition initiated by dental biofilm accumulation and characterized by gingival redness and oedema and the absence of periodontal attachment loss. Gingivitis is commonly painless, rarely leads to spontaneous bleeding, and is often characterized by subtle clinical changes, resulting in most patients being unaware of the disease or unable to recognize it.”
