2017 Classification
As defined by the 2017 World Workshop, periodontal health, gingival diseases/ conditions have been categorised into the following:
Periodontal health and gingival health
Clinical gingival health on an intact periodontium
Clinical gingival health on a reduced periodontium
Stable periodontitis patient
Non-periodontitis patient
Gingivitis – dental biofilm-induced
Associated with dental biofilm alone
Mediated by systemic or local risk factors
Drug-influenced gingival enlargement
Gingival diseases – non-dental biofilm induced
Genetic/ developmental disorders
Specific infections
Inflammatory and immune conditions
Reactive processes
Neoplasms
Endocrine, nutritional & metabolic diseases
Traumatic lesions
Gingival pigmentation

Prevention
Gingivitis can be prevented through regular oral hygiene that includes daily brushing and flossing. Hydrogen peroxide, saline, alcohol or chlorhexidine mouth washes may also be employed. In a 2004 clinical study, the beneficial effect of hydrogen peroxide on gingivitis has been highlighted. The use of oscillation type brushes might reduce the risk of gingivitis compared to manual brushing.Rigorous plaque control programs along with periodontal scaling and curettage also have proved to be helpful, although according to the American Dental Association, periodontal scaling and root planing are considered as a treatment for periodontal disease, not as a preventive treatment for periodontal disease. In a 1997 review of effectiveness data, the U.S. Food and Drug Administration (FDA) found clear evidence showing that toothpaste containing triclosan was effective in preventing gingivitis.
Nipple discharge is fluid from the nipple, with or without squeezing the breast. The discharge can be milky, clear, green, purulent, bloody, or faintly yellow. The consistency can be thick, thin, sticky, or watery.Nipple discharge may be normal, such as milk in late pregnancy or after childbirth, and in newborns during the first weeks of life. It may also be normal following squeezing, in women during the reproductive years. It is likely abnormal if it occurs in men, contains blood, is from only one breast, or is associated with a breast lump, swelling, redness or overlying skin changes. Reasons for abnormal discharge include an intraductal papilloma, duct ectasia, blocked milk duct, infected breast (mastitis or breast abscess), breast cancer, certain medications, and conditions that raise prolactin.Milky discharge in a non-pregnant, non-breast feeding women is evaluated differently to other abnormal nipple discharge. Often, the cause can be determined based on symptoms and examination. Blood tests may be done to rule out low thyroid or high prolactin. Other tests may include mammography, breast ultrasound, breast biopsy, or skin biopsy.Treatment depends on the underlying cause. Duct ectasia may be treated with surgical removal of the ducts involved. Infectious causes may require antibiotics or incision and drainage. Nipple discharge is the third most common breast complaint by women, after breast pain and a breast lump. About 3% of breast cancer cases are associated with discharge. Signs and symptoms
Nipple discharge is fluid from the nipple, with or without squeezing the breast.
