When was juvenile periodontitis discovered and by whom?

1920s: Not definitive but the earliest reference i've found from googling is a german language publication, b. Gottlieb, “die diffuse atrophy DES alveolarknochens, ” zeitschrift fur stomatologie, vol. 21, p. 195, 1923.

Dentist: See a dentist .... Juvenile periodontal disease, gum disease, is the early onset of oral disease and can be a precursor to other disease. Children need to be protected against gum disease and the loss of teeth by beginning proper oral care as infants.

Name changes: Juvenile periodontitis which used to be called periodontosis and is now called aggressive periodontitis is a genetic disease. It is characterised by a cupping out of the bone around the first molars and incisors. Generally several members have the disease and often you seeing an entire group of siblings with this disease. With early diagnosis and proper treatment this disease can be treated.
